Soy is certainly polarising. As a dietitian, I have heard it all before - Soy "increases risk of certain cancers in women", "makes men grow man-boobs", and one client even remarked that it will cause any future offspring to be born with two heads.
So who is right? Let's settle this age-old debate once and for all.
Firstly, it's a nutritional powerhouse! It's also a wonderful option for those who avoid dairy and for vegetarians and vegans alike. Those who eat soy-based foods have a lower incidence of chronic disease. Further, there is no strong evidence that it can increase a woman's risk of breast or ovarian cancer, and it certainly won't lead to the development of man-boobs. In fact, it appears to be protective of men's hearts.
Soy foods are a good source of iron, protein and calcium (when fortified), plus a host of other key nutrients. Soy milk also makes a delicious alternative to cow's milk in coffee. Just make sure it's fortified with calcium – your skeleton will thank you for it!
