During soybean in many Parts of Asia long been traditional on the plate, it has become in Western countries mainly due to vegetarianism and veganism became popular as a subsistence product for protein intake.

at least since the Veggie wave of major retailers are also set to a larger soy range: sausages, patties, Minced beef, yogurt as well as milk and soy based are available in practically every supermarket. Restaurants and cafes are increasingly offering a range of vegan dairy Alternatives are soy based.

The popularity of soy is certainly not only due to the taste. The high Protein and nutrient content and the fact that the beans contain all the essential amino acids that play a Central role.

The consumption of Tofu, it also takes a lot of unsaturated fatty acids, and avoids a rise in the cholesterol levels. Particularly natural and not highly processed soy products such as Tofu or Tempeh (fermented soy beans) also have a low fat content.

Why is soy bad for you?

With the increasing demand, but were also critical voices, the soy due to its characteristics, is unhealthy, and its cultivation for environmentally unsound: often is read, for example, to that of the soy bean contained in the substance isoflavones of the thyroid gland causing damage and even thyroid cancer. While critics rely not rarely on a Japanese study from 1991, which had come to appropriate results.

In the study, 17 subjects consumed 30 grams of soybeans a day. In half of the Participating malaise were observed, constipation, and fatigue. The researchers interpreted the symptoms as signs of a slowdown in metabolism. The study’s authors came to the conclusion that excessive consumption of soy beans, especially in the elderly limit the thyroid function and goiter formation could cause.

Around one in 100 people is affected by an underactive thyroid (Hypothreose). Women can suffer from the disease. The symptoms can be very different and may require a long-term drug therapy.

Contrary lobbying

But also on the study, there was criticism, finally, you eat, in practice, not necessarily soy beans, but vielmer soy-based produced products, which have a significantly lower isoflavone content. Isoflane is a secondary plant substance that is similar to Estrogen in its structure to the human hormone. For this reason, he is said to have an influence on the human hormone balance. However, there is now enough evidence to suggest that the substance has no negative effects on the thyroid of a healthy person.

Other studies show that consumption of Tofu reduces the risk of thyroid cancer by 55 percent. The accusation that soy consumption increased the risk for breast and prostate cancer, say other studies, the low incidence of breast cancer in East and Southeast Asia, where a high level of consumption, is low.

As with many products, some of contrary lobbying power also in the case of soy, which is fueled by skeptics and representatives of the vegetarian and vegan societies and the facts more difficult.

Small as a walnut, shaped like a butterfly: The thyroid gland. The Organ in the front of the neck area is for the survival of important hormone production. Without it, the metabolism, the circulation and the growth is not running.

we Come to the ecological aspect of soy. Anyone who eats a lot of soy, what is a vegetarian or vegan diet is often the case, must justify, often, it means: “soy is just as ecologically unsound as meat.”

will Actually be cleared, for example, in Brazil a lot of rain forest for soy cultivation. In addition, the corresponding fields are huge monocultures that destroy biodiversity and soil leaching. But the fact is that a substantial part of the soy products (approximately 80 percent) in the meat production and the share for products, such as Tofu, is vanishingly small.

it is established that a moderate consumption for healthy people safe. Not as highly processed products such as Tofu or Tempeh can make a major contribution to a rich plant-based diet.

It is a lot of pent-up demand on the part of the research is certainly in order to improve the facts about soy consumption and its effects on the body. The advantage of soybeans compared to other meat substitute products such as, for example, Seitan is that it can also consume people with celiac disease. If you buy then soy-based products from sustainable cultivation, one has to fear nothing. (gup)
