Why You Should Choose Whey Protein Over Soy Protein

The use of protein supplements is becoming popular among both athletes and non-athletes alike.

Supplements help us get in enough protein daily to help rebuild cells and tissues, protect enzyme function, keep fluids balanced, also contribute to skin, hair, and nail growth.

The use of whey protein has been declared as a great source for increased muscle strength according to an article in the British Journal of Nutrition.

whey protein vs soy protein

Between the two most popular protein supplements, soy and whey,  let me go over the one with the most benefits and which one should you avoid.

Whey Protein

Whey protein, derived from cow milk, is divided into three types.

Concentrate contains less fat and cholesterol and is the least processed type of protein.

Isolates, although contain no fat, often contain denatured proteins.

The last type, hydro-isolates are the most processed and priciest, but less allergic for those who may be lactose intolerant.

Whey protein is quickly absorbed by the body and put to use.

Essentially, it contributes to suppressing the appetite, reducing the risk of cancer, diabetes, heart disease, and providing antioxidants.

It is found in yogurt, milk, cheese, and whey supplements.

Whey provides quick energy making it a suitable pre and post-workout protein.

Soy Protein

Soy protein is derived from soybeans that are defatted and dehulled, and is processed in three forms namely soy flour, soy concentrates, and isolates.

Soy protein can be found in many foods such as bread, breakfast cereal, soup, salad dressing, infant formula, and pet food.

However, the use of soy protein raises some health concerns because of phytoestrogens found in it.

The inclusion of estrogen in our diet can be hazardous to our health because high levels of estrogen are found to be linked with cancer.

Other concerns are that soy is most often genetically modified and sprayed with chemicals and pesticides heavily.


What Protein I Decided To Use

Considering what I found out about soy, I decided to stay clear of it.

It’s just not worth the health risks.

If you decide to try whey protein be sure to always check the ingredients.

Many popular brands include artificial flavors and sweeteners so be sure to check the label and stay away from Splenda (surculose).

My Favorite Brand of Whey

I’ve been drinking whey protein shakes for years.

It wasn’t until about 5 years ago that I started paying attention to the quality.

I just didn’t know any better.

After a lot of research and experimenting, I discovered IsaPro by Isagenix.

It’s perfect for mixing into a beverage or any recipe that calls for whey protein.

It’s GMO-free, made with the milk from grass-fed cows in New Zealand, free of contaminants, and contains no artificial sweeteners.
