Explanation / Answer
1. Why are essential amino acids listed on the label for this formula?
Essential amino acids are ingested from food and usually not produced naturally by the body and include, leucine, lysine, methionine, arginine, tryptophan and others.
2. a. Do soy isolates provide all of the essential amino acids?
Unlike other plant or vegetable proteins, soy protein contains all of the essential amino acids necessary for good health. That makes soy protein a complete protein, similar to the protein found in animal foods.
b. What is this type of protein called that is found in soy isolates?
At least 60–70% of the total proteins are present in soybean.
It can contain metabolic or biologically active proteins, such as enzymes, hemagglutinins, trypsin inhibitors, and cysteine proteases. The soy cotyledon storage proteins is important for human nutrition,
3. What are the major sources of energy in this formula? Are they the same as those in breast milk?
Soy-based infant formulas were developed for infants who cannot tolerate infant formula made from cow’s milk. These infant formulas contain soy protein isolate made from soybean solids as the protein source, vegetable oils as the fat source, added carbohydrate (usually sucrose and/ or corn syrup solids), and vitamins and minerals. Soy-based infant formulas are fortified with the essential amino acid methionine, which is found in very low quantities in soybeans.
4. Why are the nutrients listed in 3 different ways:
Determining the energy content of foods depends on the components of food that provide energy and the quantity of each individual component must be converted to food energy using a generally accepted factor that expresses the amount of available energy per unit of weight.
