FAQ:

Q: Which protein powders are best?

A: Whey protein. Choose this if: You simply want the best powder to increase your protein intake or are looking to build or maintain muscle. Whey, derived from cow’s milk, leads the herd as the best type of protein powder.

Q: What is the best low cholesterol protein?

A: Chia Seeds. They’re also a good source of dietary protein for such a small serving. In terms of lowering cholesterol, chia seeds contain large amounts of soluble fiber, which is the best kind of fiber for lowering cholesterol.

Q: What is the best protein powder?

A: Derived from cow ’s milk, whey leads the herd as the best type of protein powder. It’s called a “complete” protein, meaning it contains all nine essential amino acids—the ones your body can’t make on its own.

Q: What are the health risks of protein powder?

A: Experts say too much protein can lead to dehydration and digestive problems, increase your risk for osteoporosis, and for some people, cause kidney problems. And now, an investigation appearing in the July issue of Consumer Reports finds that some protein drinks could be toxic, if you take too much.
