Foods to Avoid in Your Baby’s First Year

Foods to avoid in your baby’s first year: what parents need to know

The first year of life is a time of rapid growth and many changes. Feeding slowly moves from breast milk or formula to include new foods. It is an important stage for building healthy habits, but also for being careful about certain foods that are not suitable for babies under 12 months.

Avoiding some foods at this stage is not “overreacting” or following a trend. It is about safety, digestion, allergy prevention, and reducing the risk of infections and choking. In this article, we explain simply what should stay off your baby’s plate in the first year and how to make safer choices.

Why shouldn’t some foods be given before the first year?

Your baby’s digestive, immune, and kidney systems are still developing. Also, the way they eat at this stage is very different from an adult’s. A food that seems harmless can cause problems such as:

• choking
• allergies or adverse reactions
• too much salt, sugar, or protein
• a higher risk of foodborne infection
• digestive discomfort

So, more than simply “giving baby food,” the goal is to offer foods that are age-appropriate, safe in texture, and suitable for your baby’s stage of development.

1. Honey before 12 months

Honey is one of the foods that should be avoided in the first year of life. It may contain spores of Clostridium botulinum, which can cause infant botulism. Although rare, it is a serious condition.

Even small amounts of honey in tea, bread, yogurt, or recipes should not be offered before your baby turns 1.

2. Cow’s milk as the main drink

Before 12 months, cow’s milk should not replace breast milk or infant formula as the main drink. Babies need milk that is adapted to their nutritional needs.

In some cooking recipes, small amounts of cow’s milk may be used later on, but if you are unsure, follow your pediatrician’s advice. The key point is not to give cow’s milk as a drink before the first year.

3. Too much salt and very salty foods

Your baby’s kidneys are still immature, so extra salt is not recommended. Avoid:

• soups or purées with added salt
• processed sausages and cured meats
• ham
• very salty cheese
• packaged snacks
• heavily seasoned adult food

The ideal is to cook baby’s food without salt and, if needed, set aside a portion of the family meal before seasoning the rest.

4. Sugar, sweets, and sugary drinks

In the first year, there is no benefit in giving your baby sugar. Cakes, biscuits, sweet desserts, soft drinks, industrial fruit juice drinks, and other sugary products increase the risk of:

• a preference for very sweet tastes
• tooth decay
• extra calories with little nutritional value
• difficulty accepting natural foods

It is also important to avoid sweetened teas, sugar water, and other sugary drinks. Your baby needs to learn the natural taste of food.

5. Honey, syrups, and sweeteners in general

Besides honey, there is no reason to use sweeteners, syrups, or similar products in a baby’s diet. Some are not recommended for young children, while others encourage a habit of artificial sweet tastes too early.

The best choice remains water, breast milk, or formula, depending on your baby’s age and the guidance of a health professional.

6. Whole nuts, popcorn, and foods that can cause choking

Some foods are dangerous not because of their nutritional content, but because of how they are eaten. In the first year, the risk of choking is real. Avoid hard, small, round foods such as:

• whole nuts
• whole grapes
• whole cherry tomatoes
• popcorn
• hard pieces of raw apple
• raw carrot rounds
• large pieces of sausage

If foods with this kind of risk are offered, they should be prepared carefully: cut into small pieces, cooked, or mashed, depending on your baby’s age and eating ability.

7. Fish and seafood high in mercury

Some large fish accumulate more mercury, which is not ideal for small babies. In Portugal, it is usually recommended to limit or avoid fish with higher mercury levels, such as large tuna, swordfish, and shark.

Fish is still an important food in children’s diets, but it should be chosen carefully. If in doubt, follow your pediatrician’s advice or the guidance of the Portuguese Directorate-General of Health (Direção-Geral da Saúde).

8. Raw eggs, raw meat, and raw fish

Raw or undercooked foods can contain harmful bacteria or parasites. In the first year, you should not offer:

• raw or undercooked eggs
• homemade mayonnaise made with raw egg
• undercooked meat
• raw fish
• preparations made with questionable raw ingredients

Foods should be thoroughly cooked and prepared under good hygiene conditions.

9. Raw milk and unpasteurized dairy products

Raw milk and unpasteurized products can transmit infections. For babies, this is an avoidable risk. The best option is always pasteurized products that are suitable for the child’s age.

10. Tea, coffee, and soft drinks

Drinks such as tea, coffee, energy drinks, and soft drinks are not appropriate for babies. They may contain caffeine, sugar, or other compounds that are unnecessary and potentially harmful at this stage.

Your baby does not need these drinks. Hydration comes from breast milk, formula, and, when advised, small amounts of water after complementary feeding begins.

11. Ultra-processed foods

Filled biscuits, snacks, very sugary breakfast cereals, ready meals, and products with long ingredient lists are not a good choice in the first year.

They are often high in salt, sugar, less healthy fats, and additives. They can also make it harder for babies to accept natural and varied flavours.

12. Hidden sugar in baby products

Many parents assume that certain “baby” products are automatically healthy. But some yogurts, baby porridges, and baby biscuits can contain a lot of sugar. Reading labels helps you understand what you are really offering.

Look for simple versions with few ingredients, no added sugar, and prioritise fresh foods and homemade meals whenever possible.

How to introduce foods safely in the first year

Avoiding certain foods does not mean your baby has to eat a very limited diet. On the contrary, this stage is an opportunity to introduce a variety of flavours and textures safely.

Some good practices:

• introduce one new food at a time when possible
• offer foods that are well cooked and appropriate for your baby’s texture level
• do not add salt or sugar
• always supervise mealtimes
• adapt the size and shape of foods to reduce choking risk
• stay calm if your baby refuses a food the first time

It is normal for a baby to need several tries before accepting certain foods. The important thing is to keep offering them calmly and without pressure.

What if there are allergies in the family?

If there is a family history of food allergies, eczema, or previous reactions, it is important to speak to your pediatrician before introducing some foods. In many cases, introduction should not be delayed without guidance, but it may need closer monitoring.

We now know that unnecessarily delaying certain foods is not, by itself, a safe way to prevent allergies. Each situation should be assessed individually.

What if your baby has already eaten something unsuitable?

If your baby has eaten a small amount of a food that should be avoided, the first step is to observe them. Nothing serious does not always happen. However, seek help if there are signs such as:

• difficulty breathing
• repeated vomiting
• unusual sleepiness
• swelling of the face or lips
• hives
• persistent coughing after eating
• choking or suspected inhalation of food

If your baby is choking or having trouble breathing, this is a medical emergency.

Key takeaways

During the first year, there are foods that should be avoided for your baby’s safety and health. The main ones include honey, cow’s milk as the main drink, too much salt and sugar, choking hazards, fish high in mercury, raw or undercooked foods, and unsuitable drinks.

The most important thing is to keep meals simple, varied, and safe, while respecting your baby’s pace. If you have doubts, your pediatrician or child health nurse can help you adapt choices to your child’s age and development.

Caring about food at this stage is also a way of caring for the future: habits, health, and your baby’s relationship with food.

Frequently asked questions

Can I give my baby water before 6 months?
In general, before 6 months, breast milk or formula provides everything needed. Introducing water should follow a health professional’s advice, especially once complementary feeding starts.

Can I give yogurt to my baby before 1 year?
Advice may vary depending on the situation and the type of yogurt, but the ideal is to choose unsweetened options and ask your pediatrician if you are unsure. Cow’s milk as the main drink is still not recommended before 12 months.

Can my baby eat family foods?
Yes, as long as they are adapted: no excess salt, no sugar, well cooked, and with a texture that is safe for their age.

Do all allergens need to be avoided in the first year?
Not necessarily. In many cases, major allergens are introduced gradually and safely, with proper guidance. If there is a higher risk, speak to your pediatrician.
