Proteins for runners

[ravs2k6]

As you exercise and eat right, you'll feel your body getting stronger. Why? Because of the protein you eat. Protein builds strength in your muscles and tendons, and helps them stay healthy. It also provides energy-4 calories per gram. Meats, eggs, beans and nuts are common examples of foods that contain significant amounts of protein. Experts agree that runners need 10 to 20% of their daily calories from protein. However, most people eat two to three times their protein requirement each day! So many burgers, so little time!

Now what is better Whey or Soy protein?

[ravs2k6]

From my experience, whey protein is easier to digest and promotes energy before and/or after my daily workouts.
Whey protein constitutes about 20 percent of total milk protein (the rest being casein) and is separated out from casein and increasingly isolated to make the various whey protein products now on the market (everything from powders to various drinks and protein bars). If you're lactose intolerant – that is, if you develop digestive symptoms after eating dairy products - you may or may not have problems with whey protein products depending on the amount of lactose they contain. And if you're allergic to milk protein, it is important to know whether the troublemaker is casein or whey before using whey protein products.
