What is the difference between the difference protein powders out there? (e.g. whey, casein, vegetarian)
Answer: The key difference between whey and casein is that whey is absorbed in the digestive system quickly, whereas casein is absorbed slowly and steadily. Egg white protein was the most popular type of protein supplement for many years before milk proteins surpassed its popularity due to their better taste and lower cost. Soy and hemp are unique among vegetable protein sources in that they supply all 8 essential amino acids. Most vegetable proteins lack one or more. There also is pea protein and brown rice protein. These are for vegetarians and those who don’t do well with dairy products.
When should you use what kind?
Answer: I would use the whey upon waking and after training if you are unable to eat a solid meal. If you’re looking for a MRP [meal replacement powder] then I would use the casein as it digest slower than the whey and will stick with you longer, promoting satiety. The hemp protein would also be a consideration to be used as an MRP in a smoothie.
What kind of protein powders do you suggest and why?
Answer: I suggest whey, casein and hemp protein powders. Casein, is known for slow digestion, so it is very beneficial in shakes that are used as meal replacements or a bedtime shake. The whey is excellent before and after training as it is absorbed into the bloodstream, and utilized by the body the fastest. Hemp protein is not only is an excellent protein source but also supplies healthy fats and is high in fiber. Hemp protein also contains large amounts of zinc, iron, and magnesium and EFA (omega 3, 6, 9)
I prefer to use whey protein upon waking and after training because the body can digest and use it rapidly. I will at times you casein at night because it digests slower providing my muscles with a steady stream of amino acids.
What ingredients should people avoid?
Answer: The main thing to look for in a clean protein is lack of artificial sweeteners and information on the label stating that the protein is derived from cattle that has not been exposed to synthetic hormones, chemicals or medications. How much should a person take and how much is too much? (if exercise or meal replacement)
For people that are dairy sensitive or vegetarian what can they do?
Answer: You need at least 0.8 grams per pound and as much as 1.5 grams if you are engaging in intense exercise for more than 1 hour per day and 6-7 days per week. A 140lb woman could easily need 112 grams per day. For vegetarians Brown rice protein powder has many benefits for health and fitness. It provides a convenient source of protein for vegetarians and others who follow restricted diets. Pea protein is also something to consider if you’re a vegetarian or sensitive to dairy. Yellow peas supply an alternative but complete source of amino acids and high in iron.
The quality of proteins can be measured in two ways. The most common measure is the Biological Value (BV). The BV of certain proteins is calculated by measuring the percentage of protein consumed and absorbed versus how much of it is excreted as waste. This gives an indication of how much of the protein that is consumed actually remains within the body to promote protein synthesis Protein synthesis means how much protein the body will actually use.
I hope this clears up any misconceptions you might have had about using protein supplements, which ones, when, and how much!
