Here are some current mainstream media misconceptions regarding health and nutrition. Admittedly, most of these are already acknowledged as wrong in the same way that "all saturated fat is bad for you" is wrong, with the exception of #2:

1. Lots of cardiovascular exercise (eg running) is good for you.

2. Anabolic steroids are extremely risky and will likely kill you dead.

3. You need to eat throughout the day.

4. Whole eggs are bad for you because of the cholesterol.

5. Salt is bad for you even if you don't have high blood pressure.

6. Lots of protein is bad for your kidneys.

7. Unfermented soy is good for you.
