Avoid All Sources of Soybean Protein Avoiding products made with soybeans is difficult. Soybeans have become a major part of processed food products in our country. Soybeans and soybean products are found in baked goods, canned tuna, cereals, crackers, infant formulas, sauces, and soups.
Soybean oil is considered to be safe.
In the processing of most soybean oils, the protein portion is removed. A child with an allergy to soybeans can still have soybean oil and soy lecithin. Provide Missing Nutrients Soybeans alone aren't a major food in the diet, but because they are in so many products, eliminating all those foods can result in a vitamin deficiency. As a precaution, give your child a daily vitamin pill. Work with a dietitian to be sure your child's nutritional needs are met.
