The debate about soy has been continuing since several decades. While some people are in favor of soy as they feel they are good for health, there are others who are completely against its consumption. Both its supporters and adversaries have quite strong opinions.

Soybean is a complete and rich source of plant protein. It means that soybeans constitute of all the necessary amino acids that cannot be made naturally by human bodies.  Soy is also known to be a great source of soluble fiber and the good news is that it is low in GI and fat both.

To begin with, soy is one of the most well-researched food items on the earth so several of the myths associated with it are not necessarily true. Here are some of the common myths that are associated with Soy and an explanation of how valid these myths are.

Myth #1: Soy can lead to spreading of breast cancer

Studies have shown that regular consumption of soy foods can actually protect women against breast cancer. In fact, women who include soy food products in their regular diet have less likelihood of developing the frightening breast cancer as opposed to all those women who do not intake soy products in their daily diet. It was in the year 2008 when some researchers of the University of Southern Carolina came out with an observation that those women, who consume a half cup of tofu regularly or a complete cup of soy milk daily, are approximately 30 percent safer in terms of the perils of acquiring breast cancer. This is in comparison to all those ladies who either consume no soy products or have very little of it in their regular diets have about 30 percent less risk of developing breast cancer, compared with women who have little or no soy products in their diets. However, to be effective, the soy consumption may have to occur early in life, as breast tissue form during adolescence.

Myth #2: Soy can affect a person’s fertility

Soy Myths Busted This is absolutely false according to a report released by the Department of Health’s committee in 2003 on toxicity. The report observed that there was hardly any proof that all those Japanese and Chinese people who consume soy in high quantities regularly have exhibited changes as far as their sexual development or their fertility have got impaired. After all, one should remember that it is China that is the most populated nation in the world having a population of more than 1.3 billion people. Soy products are being consumed by the Chinese people for more than three thousand years.

As far as the female population is concerned, the Boston Fertility Center did a large-scale research that came out with a finding that when female consume soy regularly, the birth rates, for those couple, who may be going through some sort of fertility treatment, improve.

Even for men, there was no adverse impact due to the intake of soy on their fertility. Harvard University has conducted a study that observed that any type of soy intake by men was not related to the clinical results on their fertility. The study also claimed that testosterone in men is unaffected after intake of soy food items.


Myth #3: Soy constitutes of estrogen

That is not true at all as Soy does not contain estrogen. In fact, cow’s milk contains a high amount of estrogen. Soy constitutes of plant hormones that are biologically referred to as phytoestrogens but no human hormones. In human bodies, phytoestrogens are quite weak. However, they can bring several benefits like reducing the risk of cancer. It is done by obstructing the actual estrogen.

One thing is certain. Till date, there has been no concrete proof that intake of soy can disrupt sexual developments in human beings.

Soya beans are rich sources of plant proteins but it should be noted that phytoestrogens are not only present in soy products. They are also present in coffee beans and some other beans.

Phytoestrogens are also available in several other food items such as pomegranates, beer, ginseng, mint, oats and apples along with mint, carrots, rice, lentils, and flaxseed. So, that means even if you are not consuming soy, you may still intake phytoestrogens from any one of the above-mentioned food sources and it is not an issue.
