Soy - Super Bean or Super Threat II

Another Perspective
So why aren't westerners pouring soy milk in their cornflakes and chowing down on soy burgers at the local fast food restaurant? Soy still suffers from a bit of an image problem in the west. A common complaint by first-time users is that it just tastes too "beany." Still, manufacturers believe a soy revolution is coming. Soy-based yogurt, pudding, and hot dogs may soon compete with soy burgers for space on grocery shelves.

But while food manufacturers want to turn us on to soy, others feel the pro-soy movement is ignoring a host of health problems. Allergies, for example. Soy is one of eight foods responsible for the majority of food allergies, and one of five foods most commonly associated with food allergies in children. People with a soy allergy can suffer everything from hives and diarrhea to breathing difficulties upon eating this food. Furthermore. just as some people have lactose intolerance, there are others who have soy intolerance. (While food allergies involve the immune system, food intolerance is caused by an enzyme deficiency).

In recent months, soy's detractors have made other claims that are both more serious and harder to prove. For example, there is increasing concern that eating large amounts of soy can affect thyroid function. Particularly worrisome is the presence of phytoestrogens in soy-based infant formulas (isoflavones are a category of phytoestrogen). Critics point out that the level of phytoestrogens in soy-based formula is over 20,000 times that found in breast milk. In a press release last June, the Canadian Health Coalition stated that consumption of soy formulas could lead to a host of health problems, including thyroid dysfunction. They called on federal Health Minister Allan Rock to impose restrictions on the use of soy-based infant formulas. (As of this date, the Minister has not taken any action). Meanwhile, a groundbreaking study by the Pacific Health Research Institute links high levels of tofu consumption with cognitive impairment and the development of Alzheimer's disease in later life.

Super bean or super threat?
Should you swear off tofu and throw out the soy sauce? No - for one thing, the amount of soy contained in soy sauce is comparatively low, since it consists mainly of water. More to the point, the real problem is not whether soy is inherently bad (after all, people have been consuming plants with hormones for centuries) but that no one is sure how much soy it is safe to consume. While Asians have been consuming soy for centuries, there have been conflicting claims about how much soy they consume. Nonetheless, if soy starts turning up in everything from cereal to ice cream, we may begin consuming far higher amounts than is normally found in the Asian diet, without any real idea of the consequences. It's something to think about.
