Although soy is one of the best kinds of natural protein sources available, there is insufficient evidence to determine whether soy or any of its products can lower the risk of breast cancer. Likewise, there is no evidence to suggest the contrary either. However, there is absolutely conclusive evidence linking soy consumption to all types of cancer. The secret, however, lies in quantity control. For the past several years, the western world has seen the propagation of soy as an invaluable new health food for those who prefer vegetarianism as a way of life. The precedent to this practice is widely touted as the far east, specifically, countries like Japan and China, which have been shown to include soy as a main ingredient in all meals.

Soy

There is no truth to these stories, as any native or study of native behavior patterns can reveal quite easily. While soy has definitely been around for centuries and has also been a part of the diet, this has been and still continues to be so only in small quantities. For instance, there is no evidence or precedent which shows that soy was always a large part of any main course, vegetarian or not. Added as a few cubes of tofu in soups, chewed upon as a nutty snack occasionally, or even included in meals as a flour would hardly constitute using soy widely and more specifically, as a primary source of protein.

Moreover, soy in its purest form would hardly bear any resemblance to such products easily available in the market as tofu and soy milk. These are highly chemically aided and produced products that may not really be able to substitute the humble soy bean at all.  Modern soy products, especially those like the burgers, frankies and all meat look-alikes or substitutes are found everywhere in supermarkets these days. These products could be harmful as they are mostly made of soy that has been modified considerably, and they also contain numerous additives.

The truth is that while it is healthy to consume soy, as well as all other beans and legumes as part of a healthy diet and as a good source of protein, it is hardly healthy to make these the primary meal of the hour. This will have adverse effects, as would any excessive consumption of any single nutrient or food. In order to guard against soy related health problems, it is wiser to do more research before embarking upon a soy based diet.
