Babies cannot only eat breast milk all the time. When they are 4-6 months old, they need to gradually start adding complementary foods. However, it should be noted that complementary foods cannot be added indiscriminately. Many foods cannot be eaten until the baby reaches a certain age. Here are some common foods. Let’s take a look at how old your baby should be before you start eating them. 1. Table salt Strictly speaking, table salt is not an ingredient, but because it is the most commonly used seasoning, I will mention it first. Both adults and children should control their salt intake. This is because excessive sodium intake will not only lead to a heavier taste, but also increase the burden on the heart and kidneys, affecting physical health. Generally speaking, babies less than half a year old do not need any salt in their diet, including so-called children\’s soy sauce; babies under one year old can eat some salty food, but there is no need to add additional salt. The salt in the food itself is enough ; Babies aged 1-3 years old should add as little salt as possible, no more than 2g per day. 2. Eggs Eggs are rich in nutrients and relatively easy to digest, so they are the first choice of complementary foods for many mothers. However, I would like to remind you that you should also pay attention to the age of your baby when eating eggs. I recommend not eating egg yolks if you are under 6 months old, and not eating egg whites if you are under 1 year old. This is because egg whites can easily cause allergies in babies. Note that when you give your baby egg yolks for the first time, you only need to feed 1/4 of them, and you can observe the baby\’s condition afterwards. If there are no problems, you can gradually increase the amount of egg yolks consumed; if there are any allergies, it is recommended to wait until 7 months or even 1 year old before giving your baby egg yolks. 3. Honey Honey contains simple sugars, vitamins, proteins, enzymes and other nutrients, and may even relieve constipation, but it is not suitable for babies. At present, most nutrition experts recommend that babies under 1 year old cannot eat honey. After 1 year old, they can eat it appropriately according to the situation. This is because honey may be contaminated by botulinum during the production and transportation process, and babies under 1 year old have poor resistance and are prone to botulinum food poisoning. In addition, honey contains estrogen, and long-term consumption can cause the baby to develop prematurely, so even if it is over one year old, it should not be consumed for a long time. 4. Fish Fish is a good thing and helps a lot in the growth of babies, but it also has age limits. The British Food Standards Agency currently recommends that in order to avoid allergies, it is recommended that babies start eating fish and shellfish after they are 6 months old. In addition, it is not recommended to eat shark, swordfish, and marlin because these fish may contain large amounts of of mercury will affect the baby\’s neurological development. It is recommended that your baby eat fish twice a week. The preferred fish is salmon. This fish has tender meat without small bones and is rich in nutrients. It is very suitable for babies. You can then continue to add other fish, such as salmon, trout, cod, etc. 5. Nuts Nuts are delicious and nutritious, but they also present a choking hazard, so mothers are reminded that unless their baby is over five years old, they cannot eat whole nuts. Of course, if your baby is over six months old and has no family history of allergies, you can eat some crushed nuts or nut butter, such aspeanut butter. If the baby or parents have pollen allergies, asthma, eczema, etc., then the baby may also be allergic to nuts. This kind of baby should stay away from all kinds of nuts whether during pregnancy, lactation, or supplementary feeding period. Only after he is 3 years old can he gradually start to try them. 6. Beef Beef not only contains a large amount of protein and amino acids, but is also rich in various minerals, such as calcium, iron, selenium, etc. Among them, iron is not only rich in content, but also animal hemoglobin iron that is easily absorbed by babies. It is very suitable for 0.5- For 2-year-old babies who are prone to physiological anemia, it is recommended to eat 2-3 times a week. However, the meat of beef is denser and the muscle fibers are thicker, and babies’ teeth are not fully developed, so they will refuse to eat it. Therefore, it is recommended that 10-month-old babies eat dumplings filled with beef. After 1 year old, they can be exposed to poorer beef, and at 2 years old, they can eat some beef meatballs. 7. Yogurt Although yogurt can help digestion, its nutritional value is not as high as formula milk powder, so it must not be used to replace traditional formula milk powder. Note that the enzyme system that metabolizes lactic acid in your baby is still developing, so drinking too much yogurt may cause diarrhea, vomiting and other problems. In addition, yogurt is too sweet, which can easily lead to a partial eclipse in your baby. It is recommended to wait until the baby reaches 1 year old before being exposed to yogurt. When buying yogurt, mothers must pay attention to the selection, because the yogurt drinks and lactobacillus drinks in supermarkets are not yogurt, and their nutritional value is far inferior to yogurt. 8. Whole grains Whole grains are rich in fiber, which can promote gastrointestinal function and help digestion. It can also prevent various problems such as obesity, diabetes, and osteoporosis in children. Because chewing is required when eating whole grains, which not only exercises the baby\’s chewing function, but also reduces food residue residue and prevents dental caries. Although babies can start to be exposed to complementary foods at 4-6 months, they cannot eat whole grains at this time because they are not yet able to digest high-fiber foods. It is recommended that the baby be exposed to whole grains after he is 1 year old; in addition, if the baby has a bad gastrointestinal condition and often has diarrhea, he should not eat whole grains for the time being. 9. Fresh milk Fresh milk is not prepared like formula milk, so it is generally not allowed to start drinking until the baby is 1 year old. This is because milk contains a large amount of protein and minerals, but lacks complex unsaturated fatty acids and trace elements, making it difficult for babies to digest and absorb. In addition, milk contains insufficient iron and may cause allergies. After the baby is 1 year old, he can start to have contact with fresh milk. Be sure to choose whole milk. This is because fat contains vitamins A and D. If the fat in milk is removed, the vitamins will be lacking. Therefore, babies must drink whole milk before the age of 2. 10. Pineapple is a very famous tropical fruit, rich in fructose, glucose, vitamins, minerals, and very delicious. However, please note that pineapple contains three substances that can easily cause allergies in babies, so it is recommended that you wait until your baby is 2 years old before trying pineapples and other allergy-prone fruits. If your baby is prone to allergies, you should be particularly careful when eating pineapple for the first and second time. It is recommended to eat a small piece first and observe it for 2 hours. If the rash does not appear waitIf you have allergy symptoms, you can eat it with confidence. In addition, for pineapple, a fruit that can easily cause allergies, mothers can cook it before giving it to their babies, which can significantly reduce the chance of allergies.
