Soy(a), edamame, tofu, tempeh and seitan are all high-protein plant-based foods that can be a good source of nutrients for everyone. However, there are some key differences between these foods in terms of their taste, texture, nutritional content, and preparation methods.
Soya is a term that refers to the soybean plant and its products. Soybeans are a good source of protein, fibre, and vitamins B1, B2, and B3. Soy products, such as tofu, tempeh, and edamame, are also good sources of these nutrients which you’ll see listed below

It comes in a few textures also: mostly ‘firm’ which is from a curd of soy beans into a thick milk using water, nigari (sea veg which acts like a coagulant (binder) and then squeezed into solid block to drain liquid. It then absorbs flavour and works well with many cuisines.
