398. WHEY IS WAY BETTER
There are three primary types of protein supplements, soy, milk and egg, and whey. Soy is derived from plant sources and is an incomplete protein. This means it doens't contain the full compliment of amino acids. Milk and egg protein is complete but you'll need a blender to miss it. Whey is derived from milk and is the purist form of protein. You can mix it with a spoon and it doen't cause the digestive problems that often accompany milk and egg proteins. Besides being the best source of protein for building muscle, whey protein helps boost the immunity system.
399. BEWARE OF SOY PROTEIN
Soy protein has made a comeback in recent years because of some studies that suggest it can lower the rish if certain cancers. Unfortunately soy can also elevate estrogen levels. This is not a problem for females, but for a hard-training male bodybuilder, elevated levels of a female hormone is not a desirable quality. Given that soy protein mixes poorly and has been known to cause gas, we suggest you avoid soy protein.
400. USE AMIND ACID SUPPLEMENTS WITH CAUTION
As refinement techniques improved, it wasn't long before the individual amino asicds that make up protein became available. Such amino acids as arginine, lysine, glutamine, and histidine are touted to do everything from increasing growth hormone levels to speeding up protein synthesis. A few words of caution are needed. First, scientists don't know the full effects of taking high concentrations of one or more amino acids. Second, no one knows in what proportions amino acids should be consumed. Finally, amino acid supplements are much more expensive than protein supplements.
401. FRUIT FLAVOR
Despite the advances in supplement production, many people still find them rather bland in taste. One way to flavor things up is to add fruit. Place your powder and mixing mediium (milk, juice, yogurt or water) in a blender and then throw in a banana or handful of strawberries. A few seconds later you have a great-tasting protein drink fortified with extra vitamins and minerals.
