This is one of the controversial questions that has turned the health market upside down. Over the past decade, food scientists and experts have recently been pointing to soy as a possible superfood over the past few years.
Soy products, while in their organic state such as soybeans, do have some beneficial aspects to them. However, the mainstream media has failed to mention that the other forms of soy have drastic dangers to us such as infertility in women, low sperm count in men, certain causes of cancer, intestinal problems such as nausea or diarrhea and are even known to increase learning dangers in children such as attention deficit, dyslexia, and growth problems.
How have these factual side effects slipped through the cracks?
Mostly because soy milk is not 100% organic because it contains added calcium and vitamins. This is the problem with anything that has been tampered, pasteurized, or processed - You are adding non-natural nutrient ratios and in turn creating an imbalance.
So how does Whey Protein add up in the battle of soy protein vs. whey protein?
The fact of the matter is that the "soy superfood" has been dethroned by something far superior as the latest research has proved: Raw Organic Grass Fed Whey Protein.
So what exactly is Whey Protein?
Whey is a protein that comes from milk. There are 2 main proteins in milk: casein and whey proteins. Whey is acquired during the milking process when milk is turned into cheese - this is where whey liquid is separated from the casein. Ok enough of the molecular science, what does that mean?
Put it this way, this natural way of aging milk, created the number one highest quality source of protein in the world!
Whey scored a 1.14 on the "Protein Digestibility Corrected Amino Acid Score" but up until then the highest USDA score was only 1.0. Whey also scored higher than anyone thought possible! It's really that superior. But that's not all. Not only did whey protein score drastically higher than soy in Amino Acid abundancy, which are the essential building blocks of life, but it scored higher in biological value, net protein, protein efficiency, digestibility and countless others.
So is soy bad? Not necessarily. But most people over consume and take soy in different forms rather than its healthier original state. However, when it comes to soy protein vs. whey protein it is still really not a very close fight.
Simply put, raw grass fed whey is the number 1 superfood on the market these days and the highest rated protein out there. So if you can get everything you need from soy plus much more from whey then why even bother with soy?
It's a simple form of logic at this point: Put down the soy and pick up some whey.
