Are you worried about your soy intake?

Do you have such doubts? Perhaps you have a profound misunderstanding about soy.

Does soy cause allergies? Does soy intake cause male infertility? Does it contain thyroids that cause goiter? We often heard these types of questions.

In fact, there is a big misunderstanding about soy! Let the nutritionist explain and help you out!

Does Soy Cause Allergies?

Soy is an allergen, but it does not cause you to be allergic. Hence, if the child is not an allergic constitution, eating soy will not have any effect on him/her, soy does not cause allergies.

Does Soy Intake Cause Male Infertility?

A 2008 study published by Dr. Chavarro suggested that a high intake of soy foods and soy isoflavones was associated with reduced sperm count. The report raised fears among men that soy intake could lead to infertility.

In contrast, Dr. Tammay Hedlund of the Department of Pathology at the University of Colorado Medical Center responded to Dr. Chavarro’s study by saying that the study did not find a negative effect of soy on sperm motility or sperm quality. In addition, some studies have shown that soy has no negative effect on male hormones and has a protective effect on prostate cancer. Soy consumption does not pose a risk to male fertility, given that soy has been routinely consumed by generations of Asians without infertility problems. 

Does Soy Contain Thyroids that Cause Goiter?

According to the “Thyroid Disease” literature in 2006, soy intake is safe, except for thyroid problems and iodine deficiency. Thirteen of the 14 studies found that soy intake had no or only moderate effect on thyroid function.

Therefore, experts point out that soy itself is not a problem, but rather one caused by excessive consumption and the effects of genetic modification. Patients with goiter may consume moderate amounts of non-GM soy.

—– Nutritional Value of Soy —–

Of all the functional foods, soy is the one that gets the most attention. Soy is high in protein and contains all essential amino acids (the only plant source).

In addition, soy is rich in calcium, iron, zinc, phosphorus, magnesium, B vitamins, omega 3 fatty acids, and fiber. 

The gold standard for evaluating high-quality protein is the Protein Digestibility Calibration Amino Acid Score (PDCAAS). The PDCAAS of soy protein is 1.0, which can be completely digested, absorbed, and utilized by the human body. Its nutritional value is comparable to meat, eggs, and milk to meet the needs of human growth and health.

Soy is therefore the best source of protein for vegetarians.
