Once Baby Arrives - Food Safety for Moms to Be

Food Safety for Moms-To-Be Main Page

Send out those baby announcements - your bundle of joy has finally arrived! You've completed your first nine months of the journey. Now, here's how you, grandparents, and caregivers can help keep baby's food safe from here on...

En Español (Spanish)

Foodborne illness is a serious health issue, especially for your new baby and any other children in your home. Each year in the U.S., 800,000 illnesses affect children under the age of 10. Infants and young children are particularly vulnerable to foodborne illness because their immune systems are not developed enough to fight off foodborne bacterial infections. That's why extra care should be taken when handling and preparing their food.

Infants and young children are particularly vulnerable to foodborne illness because their immune systems are not developed enough to fight off foodborne bacterial infections. In fact, 800,000 illnesses affect children under the age of 10 in the U.S. each year.


Your First Step in Keeping Your Children Safe

Your hands can pick up bacteria and spread bacteria to your baby - for example, from:

  • Diapers containing feces and urine
  • Raw meat, poultry, seafood, and eggs
  • Pets, such as dogs, cats, turtles, snakes, birds, and lizards.
  • Soil

Washing your hands can remove harmful bacteria, so wash your hands often to help prevent foodborne illness. Also, teach your children how and when to wash their hands.

3 Critical Handwashing Steps

  1. Wet your hands thoroughly with warm water and add soap.
  2. Thoroughly scrub your hands, wrists, fingernails, and in between fingers - for at least 20 seconds.
  3. Rinse, then dry hands with a clean cloth towel or use a paper towel so the germs are thrown away.

"Washing hands is one of the most important actions parents can take to prevent foodborne illness in their children. " (FDA)

When to Wash

  • Before and after handling food.
  • After using the bathroom, changing diapers, or handling pets.

Who's Not Washing?

According to a Penn State University study on mothers with infants less than four months old:

41% didn't wash their hands after petting animals;

32% didn't wash their hands after changing the baby's diaper;

15% didn't wash their hands after using the bathroom;

10% didn't wash their hands after handling raw meat;

5% didn't wash their hands after gardening or working with soil.

Foodborne Illness: When to Call the Doctor

Prevention is key to keeping your baby safe from infections. However, food-handling mistakes can happen. If your baby experiences any of the following symptoms, he or she may have foodborne illness and may need to see a doctor:

  • Blood in diarrhea
  • Prolonged, high fever
  • Not taking fluids
  • Not able to keep anything down due to vomiting

In these cases, take your baby to a doctor or healthcare provider immediately. He or she can properly diagnose foodborne illness, have the specific bacteria identified if necessary, and prescribe the best treatment.

Handling Baby's Food Safely...

Protect your baby and young children by following these DOs and DON'Ts for preparing and handling their food safely.


  • Follow the manufacturer's recommendations for preparing bottles before filling them with formula or milk. Observe "use-by" dates on formula cans.
  • Check to see that the safety button on the lid of commercial baby-food jars is down. If the jar lid doesn't "pop" when opened, don't use the product. Discard any jars with chipped glass or rusty lids.
  • Use detergent and hot water to wash all blenders, food processors, and utensils (including the can opener) that come in contact with a baby's foods. Rinse well with hot water after washing.
  • Transport bottles and food in an insulated cooler when traveling with the baby. Perishable items (milk, formula, or food) left out of the refrigerator or without a cold source for more than two hours should not be used. Cold temperatures keep most harmful bacteria from multiplying.
  • Freeze homemade baby food by putting the mixture into an ice cube tray. Note: One cube equals one serving. Cover with heavy-duty plastic wrap and place the tray in the freezer. Once the food cubes are frozen, pop them into a freezer bag or airtight container and date it. Store for up to three months (discard unused food after three months). As an option, small jars can also be used for freezing. Leave about 1/2 inch of space at the top because food expands when frozen.


  • Don't make more formula than you will need. Formula can become contaminated during preparation. If a large quantity of formula is prepared and not properly refrigerated, bacteria can multiply to very large numbers. The more bacteria there are, the greater the chances for foodborne illness. Preparing formula in smaller quantities on an as-needed basis greatly reduces the possibility of contamination. If using powder, reconstitute immediately before feeding. If using liquid concentrates or ready-to-feed products, follow label instructions provided by the manufacturer.
  • Don't put a bottle back in the refrigerator if the baby doesn't finish it. Harmful bacteria from a baby's mouth can be introduced into the bottle during feeding; they can grow and multiply even after refrigeration (some bacteria can grow at refrigerator temperatures) and reheating. The temperature that's needed to kill harmful bacteria is extremely high for consumption by a baby. Also, it's not a good idea to repeatedly reheat formula because lots of nutrients can be lost.
  • Don't feed a baby from a jar of baby food and then put it in the refrigerator. Saliva on the spoon may contaminate the remaining food. Instead, put a serving size on a dish. Refrigerate the food remaining in the jar. Throw away the food in the serving dish that's not eaten.
  • Don't use honey as a sweetener to entice babies to drink water from a bottle. Honey isn't safe for children less than a year old. It can contain the Clostridium botulinum organism that could cause serious illness or death.
  • Don't give raw or unpasteurized milk or unpasteurized fruit or vegetable juice to infants or young children. Unpasteurized milk or juice may contain harmful bacteria. Unpasteurized juices are normally found in the refrigerated sections of grocery stores, health-food stores, cider mills, or farm markets. Such juices must have this warning on the label: WARNING: This product has not been pasteurized and therefore may contain harmful bacteria that can cause serious illness in children, older adults, and persons with weakened immune systems.
    NOTE: Juices that are fresh-squeezed and sold by the glass, such as at farmer's markets, at roadside stands, or in some juice bars, may not be pasteurized, or otherwise treated to ensure their safety. Warning labels are not required on these products. Young children should avoid these juices. If you can't tell if a juice has been processed to destroy harmful bacteria, either don't use the product or boil it to kill any harmful bacteria.
  • Don't leave formula out at room temperature for more than 2 hours. Harmful bacteria can grow rapidly in food at room temperature. Discard formula that's been left out for more than two hours.
  • Don't place dirty diapers in the same bag with bottles or food. Harmful bacteria from a dirty diaper can spread to baby's food.
  • Don't give infants "teas" brewed from star anise. Brewed "teas" containing star anise have been associated with illnesses affecting infants. The illnesses ranged from serious neurological effects, such as seizures, to vomiting, jitteriness, and rapid eye movement.

Two Ways to Heat Breast Milk or Formula

(for bottles with disposable inserts or hard plastic and glass bottles)

  1. In Hot Tap Water
    Place bottle under hot, running tap water until the desired temperature is reached. This should take one-to-two minutes.
  2. On the Stove
    Heat water in a pan. Remove the pan from the heat and set the bottle in it until it's warm.

Special Notes:

When heating baby's milk, always shake the liquid to even out the temperature and test on top of your hand - not the wrist (this is one of the areas least sensitive to heat) - before feeding. Milk that's "baby-ready" should feel lukewarm.

Heating breast milk or infant formula in the microwave is not recommended. Studies have shown that microwaves heat baby's milk and formula unevenly. This results in "hot spots" that can scald a baby's mouth and throat.

Safe Microwaving of Solid Foods

Studies show that the when baby food is microwaved in a jar, it's often heated unevenly. The hottest places are in the center of the foods. The coolest places are next to the glass sides, which could lead you to believe that the food is not too hot. Follow these precautions when microwaving baby's food.

  • Don't microwave baby foods in the jar. Instead, transfer the food to a dish before microwaving it. This way the food can be stirred and taste-tested for temperature.
  • Microwave 4 ounces of solid food in a dish for about 15 seconds on high power. Always stir, let stand 30 seconds, and taste-test before feeding.
  • Don't heat baby-food meats, meat sticks or eggs in the microwave. Use the stovetop instead. These foods have a high fat content, and since microwaves heat fats faster than other substances, these foods can cause splattering and overheating.

Special Note: When heating baby's food, always stir, let stand 30 seconds, and taste-test before feeding. Food that's "baby-ready" should taste or feel lukewarm.

How to Store Breast Milk

Careful home handling and storage of expressed breast milk is essential.  Here’s how to safely store breast milk:

Type of Breast Milk Countertop 77°F (25°C) or colder (room temperature) Refrigerator 40°F (4°C) Freezer 0°F (-18°C) or colder
Freshly expressed or pumped Up to 4 hours Up to 4 days with clean expression technique*

**Use within 6 months is best;
Up to 12 months is acceptable 

Thawed, previously frozen 1–2 hours

Up to 1 day 
(24 hours) 

Never refreeze breast milk after it has thawed
Leftover from a feeding(baby did not finish the bottle) Once it has been offered to the infant, use leftovers within 2 hours or discard leftovers Once it has been offered to the infant, use leftovers within 2 hours or discard leftovers Once it has been offered to the infant, use leftovers within 2 hours or discard leftovers

*Important: Before you express breast milk, wash your hands with soap and water. If soap and water are unavailable, use an alcohol-based hand sanitizer that contains at least 60% alcohol. Make sure the area where you are expressing and your pump parts and bottles are clean. Breasts and nipples do not need to be washed before pumping.

** Date your milk when you freeze it. Store breast milk in the back of the freezer, not in the freezer door. The door is the warmest spot in the freezer. This helps prevent unintentionally defrosting the milk, which can happen with frequent openings and closings of the door.

See CDC’s webpage on Proper Storage and Preparation of Breast Milk for additional information on storing, thawing, and feeding breast milk. 

Safe Storage of Baby Food

Liquids (other than breast milk) Refrigerator Freezer
Formula (stored in individual baby bottles) 2 days Not recommended
Whole milk 5 days 3 months
Reconstituted evaporated milk 3 to 5 days Not recommended

SOLIDS - opened or freshly made Refrigerator Freezer
Strained fruits and vegetables 2 to 3 days 6 to 8 months
Strained meats and eggs 1 day 1 to 2 months
Meat/vegetable combinations 1 to 2 days 1 to 2 months
Homemade baby foods 1 to 2 days 3 to 4 months

Important Tips to Remember for Baby.

  • Don't leave baby food solids or liquids out at room temperature for more than two hours.
  • Don't put a bottle or baby-food back in the refrigerator if the baby doesn't finish it.
  • To reduce the risks of choking, be watchful of babies and young children while they are eating, and teach children to chew their food well.
    (In addition, the American Academy of Pediatrics recommends that children younger than 4 years old not be fed any round, firm food unless it is cut into small pieces no larger than one-half inch.)

Risks of Cooking or Heating Baby Food in a Microwave

Following are the risks associated with cooking or heating baby food in a microwave.

  • Microwaves heat up the food unevenly. The temperature in some portion of the food may seem just right whereas some portions may be very hot forming “hot pockets” which can burn a baby’s mouth.
  • Use of cheap plastic while heating or cooking baby food in a microwave can prove harmful to a baby’s health.
  • It is believed that the radiation emitted during the cooking or heating process in a microwave can cause serious health problems.

Precautions while Using a Microwave to Cook Infant Food

Listed below are some precautions that parents need to take while using a microwave to cook food for a baby:

  • Use microwave-safe containers or heat-resistant glass containers to cook or heat baby food. Plastic containers are best avoided.
  • Cover the food with a glass plate or lid while cooking or heating the food. It will help in retaining the moisture in the food.
  • Make sure to cook or heat the food well. It will kill the bacteria, if any, and cause food poisoning to the infant.
  • Do not keep the food to cook or heat while you go about your chores in order to avoid burning the food.
  • After taking the food out, transfer it to another utensil. Then stir it well so that there are no air pockets left which may scald the baby’s mouth while eating.

Safety Tips for Reheating Baby Food in a Microwave

  • Reheating means to keep the food in the microwave until it is piping hot. This will help in destroying all the bacteria that may be there in the food.
  • Remember to check the temperature of the food before giving it to your baby so as not to scald your baby’s mouth.
  • Reheating should not be done more than once. The leftover should be thrown away even if you feel bad to waste it.

Tips to Thaw or Defrost Baby Food in a Microwave

After the first 6 months are over, babies start taking semi-solids. From heating milk in the microwave for babies, mommies start cooking food for their little ones. This is when tips to thaw or defrost baby food in a microwave come in handy. Listed below are few of them to help you sail through.

  • Always defrost or thaw baby food using a microwave-safe container, preferably a microwave-resistant glass container.
  • Do not use any plastic containers since they may give out harmful chemicals which may prove to be detrimental to the baby’s health.
  • Use a microwave that has defrost settings to thaw or defrost baby food.
  • Rotate the container manually from time to time if your microwave does not have a rotating table.
  • Stir it several times while thawing it to avoid any hot spots in the food.
  • In order to thaw the frozen food cubes, you need to put the microwave in the defrost mode for 30 – 40 seconds.
  • After the frozen food is defrosted or thawed, heat it immediately, or else bacteria may start thriving.
  • Heat the defrosted food thoroughly for 5 to 15 seconds so that it turns piping hot.
  • Keep the hot food aside till the food temperature is appropriate for the baby to eat.

Is it possible to heat up baby food in the microwave

Microwave is present in almost every family nowadays. It has gained such popularity due to the saving of time, which is always lacking for housewives, and especially for mothers with children. At the same time, disputes do not cease around the household appliance. Without an exact statement about harm to health or, conversely, benefit, young mothers are looking for an answer to the question: is it possible to heat baby food in a microwave?

Harm-benefit ratio

Indeed, researchers say that microwaved food does not lose its beneficial properties, and given the short cooking time, vitamins are better preserved. There are no residual effects in the form of radiation in the products. Another plus is that when cooking, you do not need to add fats to food, so it is more dietary. The cooking method is almost steam.

Baby food in a plastic bottle

Despite the many positive qualities, no one undertakes to guarantee the complete safety of food heated in a microwave oven. Answering the question - whether to heat baby food in the microwave for babies, experts warn: it is undesirable!

Lack of recommendations based on long-term studies. However, gastroenterologists say that breast milk heated in a microwave loses its beneficial properties. Microwaves destroy the amino acids L-proline, which are part of the natural diet and found in artificial milk mixtures. Moreover, microwave waves convert them into d-isomers. It is already known about their toxicity and negative effects on the body, in particular, the nervous system and kidneys suffer.

Tips and recipes

Microwaved baby food makes life easier for adults. But every mother will think about the health of her baby. Do not go to extremes.

Microwave water heater

Use your microwave wisely. Use the following warming recipe:

  • Since milk cannot be heated, warm it up in the old way - in a container of warm water. But the water is easily allowed to be heated in the oven.
  • If your baby is formula and you need to make formula, microwave water, not ready-made baby food. Having taken out warm water, you, as usual, can prepare healthy food.

Turn on the microwave

  • Sometimes when walking around the city or being in a cafe, restaurant, it becomes necessary to contact the staff with a request to warm up the bottle. The right decision. Just do not give the mixture to warm up, but ask for a cup of hot water. In it, calmly warm the baby's food.
  • If you still have to use a microwave oven for heating, keep in mind that you need to choose the most minimal mode with a low temperature. Try to use glass bottles instead of plastic ones.

Heating mixture in warm water

Researchers have found BPA found in plastic bottles and containers. When heated, phenol enters the food. Animal studies have caused health problems. Of course, they did not experiment on humans, but there is a high probability of a health risk. Therefore, polycarbonate bottles cannot be boiled, heated in a microwave, or washed in a dishwasher. Better yet, glassware.

Feeding a baby

Whether it is possible to heat baby food in a microwave oven, each mother decides based on her life situation. In any case, if there is no other way to heat the mixture at the moment, use the microwave with caution. Baby food in it is heated unevenly, therefore, there is a risk of burning the mouth. Trouble can be avoided by shaking the milk before eating.

Take care of your children and don't forget about your own comfort. After all, it is useful for every child to be with a cheerful, rested, loving mother. The exhausted and tired mom has the opposite effect!


Is it possible to heat the puree in the microwave. How to quickly heat up a bottle of formula in the microwave

Proper nutrition is an important factor for the normal and full development of babies. Modern technologies have made people's lives much easier, and a young mother no longer spends a lot of time heating food or defrosting food, as a microwave oven does this in minutes. At the same time, everything related to the health of the child worries her in the first place, therefore, many women during this period are worried about the question of whether it is possible to heat the mixture for feeding the baby in the microwave.

The answer to the question of whether it is possible to heat infant formula in the microwave is directly contained in the manufacturer's instructions that are attached to baby products. Both the bottle itself and the packaging of baby food contain a direct indication that the mixture in the bottle cannot be heated in the microwave.

Manufacturers of baby formula for babies in the recommendations for the preparation of infant formula say that it is not recommended to prepare a large amount of formula. If there is leftover food for babies, do not use it at the next feeding. In connection with this warning, it is necessary to prepare food in such an amount that is sufficient for a single feeding.

The main concerns regarding the harmfulness of heating food in the microwave are related to the fact that when heated, vitamins and nutrients are destroyed.

There are no definitive studies on the dangers of microwave ovens. The principle of operation of the furnace is based on the usual transfer of heat from the source to the products. In this regard, it is possible to heat water in the usual way with its help. To do this, follow the safety rules and use dishes that are suitable for heating in the microwave.

Microwave baby food

Children's food is often not reheated in the microwave, not only due to a direct ban on the manufacturer. In older children, with the introduction of complementary foods, the diet becomes more varied, and the menu contains cereals, fruit and vegetable purees. It is possible to heat up such products, but it is not recommended for a number of reasons.

The main ones are:

  • the microwave does not always heat the food evenly, which can result in damage to the dish;
  • Boiling state cannot be achieved with technology;
  • constantly checking how hot the food is;
  • bottle may explode;
  • food may burn the throat due to uneven heating.

Feeding a small child requires special control over the cooking technique, which involves boiling without salt, followed by bringing the product to the desired consistency.

The desired effect is often not achieved in a microwave oven. At the same time, with the correct implementation of the warm-up rules, it is possible to use the technique for warming up food, with the exception of infant formula or packages, the instructions for which directly state that the use of the technique is prohibited.

How to properly heat food

Use only special dishes for heating. Containers made of metal or with decorative shiny patterns are not used. It is not recommended to heat food in small glass jars, as the material heats up quickly and the food remains cold.

Microwave heating involves the use of medium modes and short process times. In most cases, the duration of the procedure does not exceed 10-15 seconds. After that, food is not immediately given to the child, it is carefully checked and, if necessary, mixed to obtain the same comfortable temperature.

What paediatricians and gastroenterologists say

Most experts will recommend using a conventional gas or electric stove to prepare baby food. You can use the microwave to heat food, except for infant formula.

The main misconceptions associated with household appliances stem from a lack of understanding of how they work.

The main ones are related to the following points:

  • microwave changes the molecular structure, and due to this, the product is heated - for this effect to occur, ionizing radiation must be present, which is not present in the oven;
  • technique destroys vitamins - the decrease in the usefulness of products occurs due to heating and does not depend on the method;
  • Carcinogens are released during the process - such elements appear only during frying, the effect of cooking in the oven is similar to a conventional double boiler.

In the microwave, food is heated by the action of waves to a depth of only 3 cm, a further effect is provided by heating from already heated layers. This feature explains why the middle of the liquid bottle often remains cold when milk is heated. To eliminate this problem, a longer warm-up at minimum power is recommended.

Which bottles are better

Only certain types of cookware are suitable for use in the microwave. Experts advise against heating in containers that contain bisphenol, since when heated, the substance is released into food and, if ingested, has a harmful effect. Such bottles and containers are marked with the code "7" or the symbol "PC". In case of doubts about the quality of dishes and the possibility of heating in the oven, it is better to use ordinary or glass dishes for these purposes.

Can baby food be cooked in the microwave? Do microwaved foods retain vitamins? How to warm up expressed milk for a baby? Is it possible to heat juices, mashed potatoes and cereals for a baby in the microwave? Such questions concern many young mothers who care about the health and well-being of their children.

Microwave and breast milk

The answer to the question about heating breast milk in a microwave oven is unambiguous. And that answer is "NO". Moreover, any manipulations using a microwave with expressed milk are strictly prohibited. Microwaves affect the living components of mother's milk, for example, immunoglobulins. As a result, they either die or their structure changes. Thus, warmed milk comes out of the oven, but no longer breast milk! And gradual heating in warm water does not cause such changes, as a result, the baby gets his favorite food unharmed. It is more correct to heat the mixture and milk in a water bath.

Good or bad?

Microwave oven heats food with electromagnetic energy. A lot of research has been done on the identification of harmful substances in dishes that are prepared with its help. Some of the scientists are sure that food from the microwave is no less healthy than when cooked and heated in the usual ways. And information about the remains of microwave radiation in food is pure myth. Since the processing time of products in the microwave is several times less, in contrast to traditional cooking methods, therefore, all useful substances are destroyed much less. Another undoubted advantage of microwave dishes is the absence of the need to add additional fats, which release carcinogens during heat treatment. The very same method of cooking is akin to steam. Be that as it may, no one is ready to talk about the benefits or harms of microwaves today.

Pediatricians do not recommend microwaving baby food in any way, simply because oven manufacturers do not indicate in the instructions how to use their products in this way. And the debate about the safety of microwaves has not yet subsided in scientific circles.

Gastroenterologists are definitely against heating breast milk in this way, since electromagnetic waves can change its structure (L-proline amino acids turn into nephro- and neurotoxic d-isomers, and they are poisonous for babies, interfere with kidney function, dangerous for the nervous system. Also, artificial mixtures should not be heated, since they have a structure similar to mother's milk, which is destroyed by electromagnetic radiation.Doctors recommend processing food intended for a child in the traditional way.In this case, a water bath is best.

Microwaves act on the water that is in the food, as a result, the water molecules begin to rotate at a tremendous speed. This is why food in the microwave cooks and heats up so quickly. However, this breaks down and changes the molecular structure of the food. Of course, each mother will have to decide for herself how to process food for her child, but the main thing is to correctly assess the benefits and risks.

It is convenient to heat baby food in the microwave - it saves a lot of time. Just a couple of minutes, and the job is done: milk, porridge or mashed potatoes are warm. But mothers are worried: does food become harmful if it is heated in a microwave oven? There are so many conflicting rumors about the influence of microwaves - what is true and what is fiction?

Microwave ovens have settled in almost every kitchen, saving time for their owners, facilitating kitchen chores. The operation of a microwave oven is based on the action of electromagnetic waves. Microwaves are harmful to humans, so there is debate about the usefulness of food prepared with their help. Many scientists claim that food from a microwave oven is completely safe, stories about the remnants of radiation in it are a myth. The power is too low to somehow affect the body.

Users ask if vitamins are preserved in the microwave. Yes, and there are more of them than in food prepared in the usual way. The reason is the short duration of the process. Dishes are prepared many times faster, less useful substances are destroyed. Another positive point is that you do not need to add oils and fats, so the food turns out to be dietary, almost like in a double boiler.

About breast milk

Breastfeeding mothers are wondering if breast milk can be heated in the microwave. Definitely - no! Expressed milk must not be heated with microwaves. They act on immunoglobulins and other living components, kill them or at least change their structure. You will get from the cell not priceless food, but a little useful liquid, comparable to cow's milk.

Heating of mother's milk in the microwave chamber is strictly prohibited - it is heated only in warm water, in a water bath.

Is it possible to heat artificial mixtures

If you need to heat artificial food, it is better to use the old proven method - hot water. But you can still take advantage of the microwave oven: heat water in it, in which you put milk or baby puree.

If you need to warm up a bottle of formula in a café, ask for a large cup of hot water. Put the bottle in it and heat the mixture.

What pediatricians and gastroenterologists say

Pediatricians do not advise parents to heat formula or heat milk in the microwave. In general, you should not cook food for kids in it - in any form, doctors insist. Disputes about the dangers of microwaves are ongoing, which means that it is not worth risking the health of a child. Manufacturers do not mention in the instructions for microwave ovens the possibility of using them for baby food.

Gastroenterologists are categorical in terms of breast milk: heating it with microwaves means radically changing the structure. Amino acids of L-proline are transformed into toxic d-isomers. These connections:

  • disrupt the functioning of the kidneys;
  • harm the nervous system.

Which bottles are better

Mom's formula is poured into bottles made of glass or plastic. It is recommended to use glass - they are safer. As it turned out, the plastic container contains bisphenol-A. When the plastic heats up, the phenol molecules are released and enter the contents. Animal studies have shown that after regularly eating food from heated plastic, health deteriorated. The impact on people has not been studied, but there is a risk - it is better to refuse plastic containers.

Polycarbonate dishes should not be boiled, microwaved or even washed in a dishwasher.

Take care of your baby, try to use the microwave oven only in extreme cases.

In today's society, every fourth family uses household appliances, because they help us save a lot of time. For example, a microwave oven is an indispensable tool for young mothers. After all, it is so convenient to heat baby puree, formula or breast milk in the microwave in just a few seconds and feed the baby.

But what happens to baby food when exposed to microwaves? How does microwave food affect a child's body? These and many other questions regarding the harm and benefits of a microwave oven are of concern to many mothers. Some argue that microwaves do no harm to food, others believe that they destroy vitamins and deprive food of useful properties.

We decided to write this article after we received a letter from our regular reader who writes...

“Hello, website editors! My name is Irina. Four months ago, I became a mother. I feed my baby with breast milk, but from 6 months, I plan to introduce complementary foods in the form of mashed potatoes into the child's diet. And I had a question: is it possible to heat baby puree in the microwave or, like our grandmothers, heat everything in a water bath? It is important for me to understand whether baby food loses its beneficial properties when heated in the microwave, and whether waves affect food in a negative way?”

So is it still possible to heat baby puree in the microwave? We offer together to understand this difficult issue and, perhaps, dispel some myths. In any case, you and only you, dear mothers, decide whether to listen to our recommendations or not.

Myth #1 Microwaves emit radioactive waves.

This is an erroneous statement. Because the waves belong to the group of non-ionizing, and there can be no radioactive impact. They in no way affect either food or the human body as a whole.

Myth #2 Exposure to microwaves changes the molecular structure of foods and they become carcinogenic.

Fortunately, this is not true either. To make a product carcinogenic is subject only to X-ray or ionizing waves. Carcinogenic substances are also released when foods are fried in hot oil. What doesn't happen when you reheat baby puree.

Myth #3 Magnetic radiation from microwaves

In fact, we are exposed to magnetic radiation every day: televisions, computers, mobile phones, radios, etc. Microwaves are no exception. Yes, its waves are more powerful, but, due to the "smart" device of the furnace and screened grids, the radiation remains inside.

Neither the walls of the cabinet, nor the doors, nor the food placed inside are capable of accumulating electromagnetic radiation of microwaves. And as soon as the oven stops working, the microwaves disappear. Waves can harm health only with a direct impact on some part of the body.

Scientists' opinions about the dangers and benefits of microwaves

For 25 years, scientists have been studying the effects of waves on the human body. As a result of experiments, it was proved that food cooked or heated in the microwave does not lose its beneficial properties at all. And in some cases, on the contrary, it is more useful and less high-calorie, since it does not require the addition of oil when cooking, unlike food cooked in a pan.

In addition, products retain 2-3 times more vitamins, as they are not subjected to prolonged heat treatment, and the cooking method is more like steam.

WHO has disproved the theory that microwaves are harmful to health. However, some baby food manufacturers advise against heating baby puree, formula, and milk in the microwave. Arguing that the microwave oven does not heat the food evenly. As a result, areas with high temperature are formed, which can burn the child. But you must admit that unevenly heated mashed potatoes can simply be mixed, and a child can get burned on food heated in any other way, if you do not pay enough attention to this. So this argument is probably weak.

Can breastmilk be heated in the microwave?

But breast milk is not so simple. Mother's milk has unique vitamins and microelements that cannot be replaced by even the best mixture. And young mothers should know that in areas with high temperatures, the destruction of useful components, such as immunoglobulins, occurs. What makes breast milk less healthy. Therefore, mother's milk, unlike baby puree, will be better heated in a water bath.

With incredible difficulty, I opened my eyes and tried to see what time it was, the luminous numbers on the electronic clock seemed blurry, and it took me time to focus my vision and see them - it's time to feed Artyomka. I slowly got up and went to the kitchen to heat up the infant formula. Then I remember everything, like in a fog, I took out the mixture, poured it into a baby bottle, added water and put it in the microwave, at that moment, without even thinking about whether it was possible to heat the baby formula in the microwave.

But I still had to look into this issue, a little later, when my mother scolded me for my indiscretion, firmly convinced that the use of a microwave oven to heat baby food is harmful and categorically unacceptable. So I wondered how it really is, is it possible to heat baby formula, breast milk, mashed potatoes and other baby food in the microwave?

Can breast milk be heated in the microwave?

It's time to admit to yourself that all the stories about the dangers of microwave ovens are a myth, and food heated in it does not harm our health. However, some products, for various reasons, are still not recommended for heating in the microwave.

One such product that is not recommended for microwave heating is breast milk.

The fact is that when heated in a microwave oven, part of the immunoglobulins and vitamins, the content of which is unmatched in breast milk, is destroyed. And from this, of course, mother's milk becomes less useful.

Can infant formula be heated in the microwave?

But in this question, you need to draw your attention to what exactly you want to do.

If you need to heat water in the microwave and dilute infant formula in it, then you can safely do it.

But it is not worth warming up the pre-prepared mixture.

And the point here is not at all in the microwave, it's just that almost all manufacturers of baby food on packages with the mixture write that you need to use it immediately after preparation. Manufacturers do not recommend leaving the milk mixture for later, even if in the refrigerator, and then reheating it.

Can baby puree be heated in the microwave?

All the myths that a microwave oven emits radioactive waves, changes the molecular structure of foods and makes them carcinogenic, are complete nonsense. There is not a single confirmation of these myths, and on the contrary, all the studies conducted over the past quarter century indicate the opposite.

Therefore, I would like to assure all mothers who are worried about the health of their children - you can heat baby puree in the microwave.

The only thing I would like to remind you is that before you start feeding the baby puree heated in the microwave, it must be mixed and tasted, as the product may heat up unevenly and the baby will burn.

Can milk be heated in the microwave?

You can heat cow's milk in the microwave.

If you decide to heat cow's milk in the microwave, you can be calm, it will not bring any harm to your health. But the benefits, most likely, too. And the point here is not at all in the microwave, but in the fact that before getting to the store counter, the milk is already processed and pasteurized in the factory. And of course, it is already difficult to talk about its naturalness and usefulness after that.

It's different when it comes to breast milk that you have expressed and now decide to warm it up. Of course, this is not worth doing. About why, we already wrote in this article, a little higher.

Is it possible to heat kefir in the microwave?

If we consider the question of whether it is possible to heat kefir in the microwave, from the point of view of preserving the benefits of the product, we are convinced that this is the most important aspect in preparing food for a child.

Then the answer will be negative, heating kefir in the microwave is undesirable.

Since most beneficial microorganisms, including lacto and bifidobacteria, die when heated. And even such a small temperature as 38-40 degrees becomes critical for their survival. But in a microwave oven, the product heats up unevenly, and in some places the temperature reaches much higher marks.

If the preservation of the beneficial properties of kefir is not in the first place for you, then you can heat it in the microwave. At the same time, of course, it will lose some of its useful microorganisms, but still it will not become completely useless. But remember that with rapid heating, kefir can curdle. Therefore, when heating kefir in a microwave oven, you should not do it longer than 10-15 seconds. If this is not enough, you can take it out of the microwave, mix it well and put it on for another 10-15 seconds.

Can cottage cheese be heated in the microwave?

Almost all fermented milk products contain beneficial bacteria - probiotics. It is they that increase the activity of immune cells, produce antibodies against pathogenic bacteria and inhibit the growth of harmful microbes, thereby creating a balance in the intestinal microflora.

Unfortunately, when heated, probiotics die, so it is undesirable for a child to heat cottage cheese in the microwave.

Heating cottage cheese in a microwave oven significantly reduces the beneficial properties of the product. In addition, this is not particularly necessary, because few children like cottage cheese in a warm form. It will be enough just to get the cottage cheese out of the refrigerator and let it stand for 30-40 minutes at room temperature.

Can yogurt be heated in the microwave?

However, like kefir, cottage cheese, and any other fermented milk products. We already wrote about this a little higher - it's all about beneficial bacteria that die when exposed to high temperatures.

If you do decide to use the microwave to warm up the yogurt, remember to remove the foil cap from the packaging.
