What is Soy?

Soy is a plant-based protein derived from the soybean. It is widely used in various forms, including soy milk, tofu, and soy protein isolates, due to its high protein content and versatility.

Soy is used in a variety of products for its nutritional value, particularly as a protein source in vegetarian and vegan diets. The health evidence on soy is mixed: it has been associated with potential heart health benefits, but there are also discussions about its phytoestrogens and their effects on hormone levels.

When you see soy on a label, it could be included for its protein content, as an emulsifier, or as a flavor enhancer. People with soy allergies should avoid it.
