The Value of Soya In Men’s Health

While there is much focus and well-substantiated research illustrating how soya plays a very important and essential role in women’s health, it must also be remembered that the scientific literature shows many benefits of the inclusion of SOY into MEN’S diets as well.

What is Soya?

Soy Beans are the most nutritious plant food available, consisting of:

  • All 3 of the macro-nutrients required for good nutrition:
    • COMPLETE protein, i.e. contain ALL the essential amino acids in the amounts needed for human health; in an amino acid profile close in quality to meat, milk and egg protein
    • Carbohydrate; and
    • Fat (soy oil is rich in essential fatty acids, phospholipids, natural sterols – all of

which have known important health benefits)

  • Vitamins (including folic acid)
  • Minerals (including calcium and iron)
  • Prebiotics (e.g. Raffinose and Stachyose, which “feed” the good colonic bacteria = probiotics, resulting in a stronger, healthier colon with enormous benefits to the immune system).
  • Fibre
  • Isoflavones (accounting for 75% of soy’s protective effects in the human body)


The definition of a complete protein:   A food that provides all essential amino acids and ensures adequate nitrogen retention and use in healthy adults.

The soy bean does contain ALL essential amino acids, thus making it a complete protein.

In addition, the  American Dietetic Association, in their Position Statement on Vegetarian Diets, indicate that based on the protein digestibility-corrected amino acid score, which is the standard method for determining protein quality, it has been found that isolated soy protein can meet protein needs as effectively as animal protein.


Scientific studies show that soya plays a role in the treatment and management of certain chronic diseases, including:

  • Hypertension
  • High Cholesterol levels
  • Obesity
  • Cardio-vascular disease
  • Diabetes


A meta-analysis done in 2012 showed that soy (isoflavones) had an effect of lowering blood pressure in people with hypertension (high blood pressure), but not in those with normal blood pressure


Soy foods may help to prevent heart disease by reducing total cholesterol, and specifically LDL-cholesterol levels, and possibly preventing plaque build-up in the arteries (atherosclerosis).


Soya products are low GI and as such assist in stabilizing blood glucose levels, thus preventing insulin resistance, metabolic syndrome and pre-diabetes.

  • The products are filling, and act as a natural appetite suppressant, preventing one from over-eating at meals.
  • Soya is low in the type of fats that cause visceral fat gain around the abdomen.
  • The Soya Life Meal Replacement drink offers a controlled calorie meal, and as such enables one to control overall daily calories better.


  • Soya fibre helps stabilize blood glucose levels
  • Soya products have a low Glycaemic Index, preventing blood glucose fluctuations
  • In addition, an important study conducted proved that a soy rich diet reduces the risk of complications in diabetes, specifically cardiovascular disease and renal disease


Protection against cancer:

Most epidemiological and clinical studies involving humans (NOT rodents / cultured cells) demonstrate a positively protective effect of soy.

Of relevance to men: particular benefits exist for protection against cancers of:

– prostate:

– stomach:   a 2013 study illustrated that frequent soybean intake was associated with lower risk of gastric cancer
