The American Academy of Pediatrics AAP, and the World Health Organization WHO all recommend that milk can be used instead of formula after the baby is 1 year old.

Parents are not obliged to provide the main source of nutrition for their babies through formula milk. Because after the baby is 1 year old, there should be a gradual transition from milk to meals, and eventually three meals a day is the main source of nutrition for the baby.

In the past, milk powder was drunk by small children, but now gradually emerged adult milk powder, mainly to supplement the body's nutrition, so what is the difference between infant milk powder and adult milk powder? Can they be exchanged and drunk?

The difference between infant formula and adult formula is definitely not as simple as infant formula is more nutritious, the nutrition required by infants and adults, as well as the gastrointestinal digestive function is different, just infant formula is divided into 1 paragraph (0-6 months of age), 2 paragraphs (6-12 months of age), 3 paragraphs (more than 1-year-old) and other such segments, small month-old babies can not drink high sections of infant formula, not to mention with adult formula than.

In other words, infants can never drink adult formula, and adults are not recommended to drink infant formula. First of all, it is generally difficult for adults to accept the taste of infant formula, which is very fishy and even difficult to swallow.

Secondly, adults who drink infant formula are prone to gastrointestinal discomfort. This is a digestive disorder caused by the proportion of milk powder ingredients and the adult's unequal nutritional needs.

The protein content of infant formula is about 1/3 of that of fresh milk, while the lactose content is very high. The main source of energy for infants is lactose, and the digestion of lactose by the intestines is very strong, while the digestion of protein is weak.

Adults, on the contrary, are far less able to digest lactose than infants and need to be supplemented mainly with protein and vitamins, so adults who drink infant formula with high lactose content not only do not absorb the nutrients in place but also cause "indigestion" of lactose, manifesting as bloating, diarrhea and other symptoms.

So what is the general nutrition of infant formula? As we all know, the 7 basic nutrients required by the normal human body include protein, fat, carbohydrates, vitamins, minerals, water, and dietary fiber.

Among them, protein, fat, and carbohydrates are caloric nutrients that provide the body with a source of energy; while vitamins, minerals, water, and dietary fiber do not provide the body with energy, but have an indispensable and important role in maintaining the health of the body.

The infant formula must contain the following five major nutrients, protein, fat, carbohydrates, minerals, and vitamins.
