soyfree

Soyfree is a dietary designation for diets or foods that avoid soybeans and products derived from soy. It is most often chosen by people with a soy allergy or soy intolerance, but some individuals restrict soy for personal health beliefs or as part of broader allergy- or elimination-based eating plans.

Common ingredients and foods to avoid include soybeans and edamame, tofu, tempeh, miso, natto, soy sauce, tamari, soy milk, and products containing soy protein isolates or concentrates. Soy lecithin is a frequent ingredient in processed foods and may appear in baked goods, chocolates, and candy. Other potentially problematic ingredients include hydrolyzed vegetable protein and textured vegetable protein. Some foods may be processed in facilities that also handle soy, creating cross-contamination risks. Labeling rules vary by country, but many jurisdictions require disclosure of soy when present, and products may indicate "contains soy" or "processed in a facility that also processes soy."

People following a soyfree diet must read ingredient lists carefully and be aware of hidden sources like flavored chips, soups, and restaurant sauces. Cooking from whole foods can simplify adherence.

Common alternatives include dairy or non-dairy milks (almond, oat, rice, coconut), meat substitutes based on ingredients other than soy (pea protein, wheat gluten, mushrooms), and naturally soy-free grains, fruits, vegetables, and legumes. When in doubt, consult a healthcare provider or registered dietitian, especially if a soy allergy carries the risk of anaphylaxis.
