Foods prohibited in the diet of babies under one year


Discover the foods prohibited in the diet of babies under one year.

Until the year the baby’s main food is milk and, from the age of six months, they are ready to start trying all kinds of foods.

It is time to start with complementary feeding, a challenge for the little ones, who have to get used to a whole new world of textures and flavors and, until recently, a real headache for parents due to the complicated and strict guidelines of the introduction of the foods that the pediatricians gave us.

Now things have changed and babies can eat almost anything from the time they are six months old. There are only a few foods that are prohibited before the first year.


Big fish

Due to its mercury content, in children under three years of age, it is necessary to avoid the consumption of swordfish or emperor fish, shark, pike, dogfish, blue shark, and tuna (in children between 3 and 12 years of age, limit it to 50 gr./week or 100 gr./2 weeks and not consume any more of the same category the same week).

In addition, because of the presence of cadmium, children under three years of age should avoid regular consumption of the heads of prawns, prawns, and Norway lobsters or the body of crab-like crustaceans.


It is not suitable for your kidneys in the process of maturing. Another compelling reason to avoid its consumption is that children do not need us to add additives to food to find it tasty since for them the taste of potatoes, carrots, or meat is completely new.

If what we want is for them to get used to identifying the different foods and knowing the flavor of each one, better than nothing interferes with that process.


If we give baby food jars, let’s make sure that they do not contain salt in their composition for children under one year of age, and if, from this age, we want to add a little to their meals (always in a small quantity and the later the better) that it be iodized.

Vegetables in vinegar and certain preserves, salted meats and sausages, cubes of broth, or powdered soups are not recommended either.

Be careful with the harmless foods that we give to babies, such as chicken or turkey cold cuts. They are not a recommended food for them, first because it is processed meat and second because they usually have a lot of salt.

In the case of processed foods, it is considered:


•High salt content: 1.25 gr. of salt or 0.5 gr. of sodium for every 100 gr. of product

•Low salt content: less than 0.25 grams. of salt or 0.1 of sodium for every 100 grs. of product


Spinach and chard as a single dish

The Spanish Food Safety Agency recommends, as a precaution, not to give spinach or chard to babies before the first year of life. for its nitrate content.

In the case of including these vegetables before the year, it is necessary to ensure that the content of spinach and/orchard is not greater than 20% of the total content of the food ration. Between 1 and 3 years it is recommended not to give more than one serving of these vegetables per day and avoid their consumption in children with gastrointestinal infections.



It is dangerous because it can cause botulism, a rare disease (in Spain there are 110 cases a year), but it can be very dangerous. In addition, it is recommended not to offer until at least 3 years of age because it is highly cariogenic.

Whole nuts

They are small, round, and do not melt in the mouth, which is why nuts are one of the foods most likely to cause choking. Experts recommend not giving them whole until 3-5 years old and always with caution.

Nuts can be taken from 6 months ground in different preparations. Also, be careful with round solid foods such as sausages or whole grapes (you have to cut them lengthwise) and other hard foods such as raw carrots or apples. Also, be careful with popcorn, the recommendations are the same as for dried fruit.

Whole milk and its derivatives

Because the excess protein and minerals, they contain can be harmful to a baby’s kidneys. Breast milk has about 1 gr. of protein per 100 ml. (formula something more), while cow’s milk has 3.3 gr. for every 100 ml.


Babies aren’t able to fully digest it because their kidneys aren’t able to filter out all the excess nutrients they’re getting. In addition, it can cause anemia because it decreases the absorption of iron.

Meat, fish, and rare egg

Never offer these foods raw or cooked at less than 70º, the temperature at which pathogenic microorganisms are destroyed. It is necessary to wait until 3-5 years, the same as for slightly mature cheeses made with raw milk since it is possible that the thermal or curing process of these foods has not eliminated the risk of the presence of pathogenic bacteria such as salmonella, campylobacter, listeria or Escherichia coli.

Remember that these recommendations also go for the fried egg, the soft-boiled egg, and the raw egg that we can find in preparations such as meringue or homemade mayonnaise. The French omelet or scrambled eggs can be taken as soon as the whole egg is introduced, always well curdled to avoid the risk of salmonellosis.


Children under 6 years of age should not consume meat from animals hunted with lead ammunition or its derivatives because it causes neuronal damage.


Sugar and superfluous foods

Sugar, under any of its names, is an unnecessary food, both in the diet of children and in that of adults. It is cariogenic, demineralizes, does not provide anything nutritionally, is addictive, and is also directly associated with childhood obesity.

So, the goal is to delay its introduction as long as possible and never before the first year (you can know the sweet flavors through the fruit). The same for superfluous sugary foods such as jams, cocoa, and chocolate, flans and dairy desserts, cookies, or pastries.

Taking into account this list of prohibited foods during the first year of life, our baby will be ready to start trying almost everything from six months.
