Choosing the right milk for children with g6pd deficiency

Milk is an essential part of a young child’s daily diet. It contains vital nutrients which help with their healthy growth and development. However, if your child has G6PD deficiency, choosing a suitable milk product can be challenging. Children with G6PD deficiency must avoid products containing Soy, but this ingredient often appears in various forms in many milk supplements and drinks. This article provides important information to help you identify if your child's milk product contains Soy ingredients.

What is Soy?

Soy or soybean is a type of legume widely used as a functional ingredient in many food products. Isolated protein from soybeans is a common food ingredient used in many milk formulas and supplements because it is high in protein and easily digestible. Oil byproduct of soybeans is also widely used as a source of linoleic acid. Some byproducts of Soy are also used as emulsifiers in powdered milk drinks. Despite its good nutritional and functional qualities, milk products containing Soy ingredients are unsuitable for children with G6PD deficiency.

Why is Soy harmful for children with G6PD deficiency?

According to the G6PD Deficiency Association, food items containing Soy and other legumes (e.g, Fava or broad beans) may cause damage to the red blood cells of children with G6PD deficiency.  In addition, The National Institutes of Health-Philippines strongly recommends avoiding food and drinks with Soy.
