I think this is the answer- They decrease blood cholesterol levels.
Explanation:
At least 10,000 different proteins make you what you are and keep you that way. ... naturally low in sodium, and contains just over 1 gram of saturated fat.
Studies have shown that whey protein given as a supplement lowers both LDL and total cholesterol as well as blood pressure.
It's actually it's high in saturated fats. As in red meats, etc. or perhaps bacon although it tastes delicious. As we know saturated fats are the unhealthy fats..... not to mention I got A 100% on my quiz. LOL
