Can baby food be microwaved? Mommy Asks — Little Melly, Organic Baby Food

Okay. Simple question, complex answer.

However, we’re going to do our best to offer our motherly advice to you.

Numerous research studies and experiments have been made to decipher whether microwaves are safe for heating food or not. At times, the verdict was that it isn’t safe, and at other times, the verdict was that it’s totally safe. This has caused great confusion among consumers. Researchers have also tried to examine whether microwaved food has a direct link to certain cancers. We wish we could give a simple yes or no, but there’s more to it.

How do microwaves work?

Microwaves can be compared to the sun; they work in a similar way: using radiation (Woodford, 2019). Similar to the way the sun’s radiation hits our face, microwave radiation hits the food. It’s important to note that the radiation itself is not harmful and does not remain on the food. However, microwaves are able to heat the food so quickly because the heat energy hits straight into the molecules of the food (Woodford, 2019).

That, dear parents, is why we personally don’t favor the use of microwaves.

What does a microwave’s heat energy do to food?

When heat energy is directed straight into the molecules of food, the composition of the food is changed. We don’t see it or feel it, but the food is no longer in the same make-up as it was when we first cooked it. In simple terms, when we eat microwaved food, our body identifies it as something foreign because it does not recognize this new composition, meaning our body signals itself to reject what just entered into the body. Do we feel this rejection? Nope. At least not in the present moment.

As our body continually consumes microwaved food, our antibodies are continuously activated in order to reject the “foreign” substances. This means our body is always in attack mode. With time, this deteriorates the health of our cells and greatly affects our long-term health.

We will not go into the side-effects of microwaves, as it is outside the scope of this blog post and a debate among researchers. For now, our responsibility is to safeguard our parents regarding the best method of heating food, for themselves and for baby.

What is the best method to heat baby food?

As per food safety guidelines, reheating cooked food should be done only once and when reheating, the temperature of the food should reach 75 degrees Celsius. This guideline is set for your safety: so that any bad bacteria can be reduced to an acceptable level before consuming.

Bad bacteria is killed at high temperatures. When we cook our baby food at the Little Melly kitchen, we ensure that the contents reach a temperature of at least 75 degrees for around 5 minutes. This is a critical point in our process to ensure food safety. When packaging and storing food, whether at our premises or in your home, there is a chance for cross-contamination and multiplication, thereby increasing bad bacteria within the food once again. To combat that, we reheat at a high temperature before eating to kill anything that has grown.

How should you heat?

  1. On a stove pan with low flame for a few minutes. A trick we like to use is to add some drinking water to the mix in order to facilitate the heating process and give the mixture a nice consistency to it. This is especially helpful when the meal was prepared a day in advance and stored in the fridge.

  2. Using the bain-marie method, by placing hot water in a heat-resistant bowl and then placing the baby food jar in the bowl until the food has become hot. There are some cautions to watch out for when using this method, however. Firstly, placing a glass jar in hot water may cause the jar to crack (especially if the jar is coming straight out of the fridge). The drastic variation in temperature causes this. Second, the bain-marie technique often needs to be repeated at least twice for the food to become consistently hot.

*Caution: No matter the method you choose, make sure to slightly cool your baby’s food before serving it to them. Hot food can damage your baby’s tongue, gums, and mouth.

Does this mean I should throw out my microwave?

No. I would be lying if I said I didn’t ever microwave my own food. For little Melanie, I try to never ever use the microwave, but I can’t deny that I use it for my own food occasionally. It’s a practical and efficient way to heat food, and using it every now and then will not do harm to your body. Our motherly advice says: use a stove to heat food whenever possible.

Microwave baby food: can or can't be reheated

Microwave baby food is easy to reheat - 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?

Useful or harmful

Microwave ovens have settled in almost every kitchen, save time for their owners, facilitate 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. nine0003

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 there is no 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 wonder 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. nine0003

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. nine0003

What pediatricians and gastroenterologists say

Children's doctors advise parents not 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 best

Mothers pour their baby formula 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 abandon plastic containers. nine0003

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.

Is it possible to heat baby food in the microwave: expert's answer

Absolutely all loving mothers worry about the health of their babies and place special emphasis on the quality of their nutrition. The question of whether it is possible to heat baby food in the microwave is more than relevant. On the one hand, you do not need to spend a lot of time and effort on this, on the other hand, the electromagnetic radiation of the device raises doubts.

Now almost every home has a microwave oven, because it greatly facilitates the kitchen life and helps in cooking, allows you to heat up food as quickly as possible. nine0003

Research shows that microwaved food retains its vitamins. Food does not lose its beneficial properties. Electromagnetic radiation does not affect the quality of products.

However, all this applies to standard food. When it comes to milk or other infant formula, things are different. Experts do not recommend frequently heating food in the microwave. According to gastroenterologists, breast milk in this case will begin to lose its beneficial properties. nine0073 Due to the action of microwaves, L-proline amino acids, which are the basis of both natural nutrition and artificial mixtures, are destroyed. Among other things, under the influence of microwave waves, they turn into d-isomers, which are far from the best effect on the kidneys and nervous system.

Don't panic though, there is an easy way to warm baby food. To do this, you only need a container of warm water. It, in turn, can be heated in the microwave. The bottle should be placed in a container and wait until the mixture reaches the required temperature. The same can be done in a cafe or restaurant. It is only necessary to ask the waiter to bring a cup of hot water, in which it will not be difficult to warm the food. nine0003

If you cannot do without a microwave oven, you should choose only the lowest settings with the lowest temperature, and also use glass bottles, not plastic ones.
