Tofu: Tofu or soy bean curd is another excellent high-protein meal base and source of healthy fats and nutrients. Because it absorbs flavors so well and can be cut into cubes, strips, or chunks, it can be prepared in a variety of ways. Plus, some research has shown that soy consumption can reduce risk of breast or prostate cancer, thanks to its high levels of phytoestrogens, though that link is still being studied.
