Which protein powders to avoid?

People should not consume certain types of protein powders. These include:

1) Soy Protein Isolate

Soy protein isolate is made from soybeans. This type of protein powder is prevalent among bodybuilders and athletes. However, this type of protein powder does not contain any essential amino acids. It also contains anti-nutrients such as phytates and goitrogens.

2) Hydrolyzed Vegetable Proteins

4) Artificial Sweeteners

Artificial sweeteners are usually found in protein powders. They do not provide any nutritional value, and they cause weight gain.

However, some people who tolerate dairy products well still find they react negatively to the best casein protein powder.
