Infant formulas made with soya are exclusively made with this plant. To avoid any confusion, it is forbidden to call them "soy milks". These products also have nothing to do with adult soy beverages. Preparations can be recommended in case of digestive problems of baby.

Indications for soy preparations

Soybeans, traditionally grown in the Far East, have recently appeared in the western diet. Its nutritional characteristics, in particular its richness in protein and fat, and its low cost have made it adopted in many countries. Soy preparations differ from traditional milks since they are exclusively of vegetable origin. They contain neither proteins nor lipids of animal origin and none contain lactose. Transgenic soya is not used. Soy allergies are possible and there is a frequent cross-allergy between PLP allergy and soy protein allergy.

Soy beverage

The caloric intake is identical to that of mother milk around 700 Kcal / l.

The distribution of proteins, lipids and carbohydrates in the total energy intake differs according to the products compared to the mother's milk.

Soy preparations contain 20 to 25 g / l of isolated soy protein. This high content is explained by the fact that the biological value of soy protein is of lower quality, the increase in the intake allows better absorption.

The lipid content varies from 28 g / l to 36 g / l depending on the brand. It is therefore lower than that of mother milk (40 g / l). The supply of essential fatty acids is nevertheless guaranteed. Because of the low carnitine soy compared to mother milk and the major role of this amino acid in the oxidation of long-chain polyunsaturated fatty acids (PUFA), soybean preparations must be fortified with L-carnitine according to European Directives. The lipids are exclusively oils of vegetable origin.

The carbohydrate content varies from 66 g / l to 87 g / l (mother milk = 70 g / l). Carbohydrates are starches and polymers of glucose: there is therefore neither lactose nor sucrose. The levels of minerals and trace elements (calcium, phosphorus, iron, zinc, etc.) are higher than those of mother milk, but their bioavailability is of lower quality. The presence of phytate in soy proteins acts as chelating agents and reduces intestinal absorption. The vitamin D enrichment complies with the legislation.

The indications for soya preparations are discussed.

In case of primary or secondary intolerance to lactose, soy milks are usable as well as in galactosemias and intolerances to sucrose. It is usual to try them in the case of bloating, regurgitation, appetite disorders, common acute diarrhea in infants over 3 months, idiopathic colic and eczema. In case of intolerance to proteins in cow's milk, they are recommended in case of suspicion of allergy to cow's milk proteins (APLV) in its enteropathic form (chronic diarrhea) but contraindicated in the mediated IgE form Anaphylactic shock, urticaria, asthma, diarrhea Immediate vomiting, Quincke edema) due to the risk of "crossed" allergy with POPs (approximately 5% of children without factor). >
They are also used in vegetarian or vegan diets, which are totally unsuited to infant physiology.

Soya preparations proposed for infant feeding should not be confused with "soy beverages", which are increasingly appearing in dietary stores and supermarkets. These drinks are far too high in protein, low in fat, low in cholesterol, low in carbohydrates, iron, calcium and calories. Some of these drinks are flavored (fruit, chocolate, coffee ...) to mask their bitter taste and are then too sweet (120 g / l of carbohydrates). These products are not suitable for young children.
