Whey Protein Facts – Learn More About Whey!

Whey proteinToday it’s time to learn a bit more about whey protein! Whey protein is the most popular supplement used amongst athletes, and some would argue the most important. Let’s have a look at some of the facts about whey protein:

Whey Protein Facts:

  1. Whey protein has a complete amino acid profile. This means it has the optimum amounts of all aminos needed for muscle repair. For this reason, whey protein is the preferred type of protein to be taken post workout.
  2. Whey has the highest biological value (BV) of all protein sources. Biological value is a measure of how fast the body can use a protein source. Eggs are 100, whey protein isolate can be up to 180.
  3. You can increase the update of whey protein (and other supplements like creatine, glutamine etc) by adding high GI (glycemic index) carbohydrates to your post workout shake. The high GH carbohydrates induce an insulin spike. Insulin delivers nutrients to muscles incredibly fast. The best for of high GI carbohydrates to add to your shakes is dextrose.
  4. Whey protein helps athletes maintain a healthy immune system by increasing the levels of glutathione in the body. Glutathione is an anti-oxidant required for a healthy immune system and exercise and resistance training may reduce glutathione levels. Whey protein helps keep athletes healthy and strong to perform their best.
  5. Whey protein is also great for weight loss. It’s very low in calories and helps promote a fast metabolism. Protein takes a lot more energy to digest that carbohydrates or fat.
  6. All whey protein powders contain the powerful amino acid glutamine. Glutamine aid in muscle repair (helps to build muscle) and is the immune system’s main source of fuel. Different products have different amounts of whey, it’s something to look out for when purchasing a product.
  7. Whey protein has been used in connection with a variety of conditions including cancer, stress and HIV infection.
  8. Whey protein is an excellent source of the essential amino acid, leucine. Leucine is important for athletes as it plays a key role in promoting muscle protein synthesis and muscle growth. Research has shown that individuals who exercise benefit from diets high in leucine and have more lean muscle tissue and less body fat compared to individuals whose diet contains lower levels of leucine. Whey protein isolate has approximately 50% more leucine than soy protein isolate.
  9. Whey protein isolate is pure protein with little to no fat or carbohydrates. It is a perfect complement to any low carbohydrate or low glycemic index diet plan.
  10. For people with type 2 diabetes, adding whey to high-carbohydrate meals stimulates insulin release and reduces spikes in blood glucose levels after meals.
  11. Whey protein is a rich source of branched chain amino acids (BCAAs), containing the highest known levels of any natural food source. BCAAs are important for people wishing to build up muscle, since unlike the other essential amino acids, they are metabolized directly into muscle tissue and are the first ones used during periods of exercise and resistance training. Whey protein provides the body with BCAAs to replenish depleted levels and start repairing and rebuilding lean muscle tissue.
