Soy Protein
What is Soy Protein?
Soy protein is derived from soybeans and is a rich source of plant-based protein. It is made by grinding soybeans and separating the protein from the rest of the plant components, usually through a process involving defatting.
It is widely used in food and supplement products to increase protein content and is popular among those seeking non-animal protein sources. Health evidence around soy protein is mixed; while it is associated with benefits like lowering LDL cholesterol, some concerns persist about hormone interactions due to its isoflavone content.
When you see soy protein on a label, it's important to consider any personal allergies or dietary preferences, particularly regarding GMOs, as soy is often genetically modified.
Commonly found in: protein shakes, meat alternatives, baked goods, supplements, protein bars, processed foods
