SOYBEANS AND SOY-PROTIEN

Soy-protein is a protein derived from soybeans a crop grown in many regions of the world. Soy protein is isolated from soybean which has been dehulled and defatted to form soy flour, concentrates and isolates. It is one of the plant sources to have a complete amino-acid profile. Well, other plant protein sourced are also great at building muscle and sustaining a healthy life.

Soy flour consist of 50% protein

Digestibility of some soy foods:-

  • Steamed soybeans-65.3%
  • Tofu:- 92.7%
  • Soy milk- 92.6%
  • Soy protein isolate- 96%

We will focus on some of the myths in the food and health industry regarding soy

“Soy has estrogens” “gynecomastia”- this is a false claim as soy doesn’t contain estrogens (cow’s milk contains plenty of mammalian estrogens which affect human body). Soy contain phytoestrogen which is a plant hormone which are relatively weak and can actually bring benefits such as lower risk of cancer.

There has been no evidence of soy disrupting sexual development in humans

If you are worried about phytoestrogen, it should be noted than phytoestrogen are not only found in soy but in other plant foods like coffee bean, apples, oats, sesame, flax seed, lentils, rice, carrots, mint, ginseng, beer and pomegranates.

Gynecomastia and soy has been related on just one single case study(scientifically weak) which reported a 60 year old man developing breast as well as sexual dysfunction after claiming he has consumed 3 litres of soy milk daily for 6 months. We don’t know the underlying medal history of the man and no proper documentation is found.

(isoflavons and phytoestrogen are powerful anti-oxidants and have positive effect on our body)

“soy affects fertility”- no evidence has been found against such a claim. Japanese and Chinese who have altered sexual development and impaired fertility consume high quantities of soy. China with a population of 1.3 billion citizens have consumed soy for over 3000 years.

It is shown in a large scale study at Boston fertility centre that soy improved birth-rates for couple undergoing fertility treatment

And also for men had no negative impact on fertility. Harvard study shows men’s soy intake has no effect on the outcome on fertility

Met analysis showed that soy intake had no effect on the sperm concentration, count of mobility and no observable changes in testicular or ejaculated volume.

When we compare soy milk to cow’s milk, cow’s milk has 80% of you dietary intake of estrogens because cow’s milk is taken while the cow is pregnant and nursing, their estrogens levels are pretty high and dairy livestock are also given hormones to increase growth and milk production

Soy milk has much less saturated fat (60% less than cow’s milk(1% fat))

Soy milk has a little less calcium than cow’s milk but 3 times the amount of magnesium which is a vital mineral for bone health.

Many people have lactose intolerance, and far less people have issues digesting soy and soy products.

Soy milk is much better than cow’s milk for bone health based on recent research

Osteoporosis is much more in countries with high cow’s milk intake and lowest in countries with high soy intake.

Most of these soy myths are coming from a single group called Weston A Price Foundation(WAPF) which is a multimillion dollar operation that lobbies for raw milk and grass fed beef and soy is a competitor for them, they have been accused of distributing falsified information regarding soy for their personal gains.

Soy industry has increased from $500 million to $5.2 billion dollar . soy industry is increasing and WAPF is trying to peddle.

So it is recommended not to fall prey to these wrong campaigns and act as per scientific knowledge.
