Is soy a safe alternative? And what exactly are all of those soy alternatives in the Supermarket? Find out here
Should you stock up on soy? Well, a study recently presented at the American Association for Cancer Research demonstrated that soy food intake among breast cancer survivors is safe and may even reduce the risk of recurrence. The study’s authors stress that the study reviewed soy foods, not supplements. Many cancer survivors have feared eating soy foods, worried that soy would increase their risk of a cancer recurrence, but new research suggests that those worries appear unfounded. The studies authors comment that soy contributes to an overall healthy diet pattern, and healthy diet patterns are linked with lower recurrence and general wellbeing.
So how much soy is considered protective? Just a cup of soy milk or just two ounces (or half a serving) of tofu per day. And what are some of the different types of soy foods in the store?
Soy milk: soybeans, soaked, ground fine and strained, produce a fluid which can be substituted for cow’s milk. Plain, unfortified soymilk is an excellent source of high quality protein, and B-vitamins.
Soy yogurt is made from soymilk. It has a creamy texture similar to dairy yogurt, sour cream or even cream cheese. It can be found in variety of flavors in the refrigerated section of your grocery store.
Tofu: is also known as soybean curd, is a soft cheese-like food made by curdling fresh hot soymilk with a coagulant. Tofu is relatively tasteless and easily absorbs the flavors of other ingredients with which it is cooked. It is rich in high-quality protein, B-vitamins and low in sodium. Firm tofu is dense and can be cubed and served in soups, stir fried, or grilled; it’s higher in protein, fat and calcium than other forms of tofu. Soft tofu is good for recipes that call for blended tofu. Silken tofu is a creamy product and can be used as a replacement for sour cream, ricotta cheese (etc) in dip recipes.
Tempeh: is a combination of whole soybeans, sometimes mixed with another grain such as rice or millet. It is then fermented into a rich cake of soybeans with a smoky or nutty flavor. Tempeh is commonly marinated and grilled and added to soups, casseroles, or chili.
Soy Cheese: Made from soybeans therefore a veggie cheese. Its consistency and texture is lighter and some brands are difficult to use in dishes that require melting. Soy cheese makes a great addition to sandwiches or salads. Soy cheese is available in many varieties similar to dairy cheeses.
Soy flour is made from roasted soybeans ground into a fine powder.
