4 myths debunked

I was reading in my consumer health text book today and found this nugget of information. I feel like a lot of people fall prey to some common health myths that I'd like to clear up right now.

1. Most people who take vitamin supplements don't need them.
2. Vitamins do not make people more energetic, more muscular, or less stressed.
3. "Organically grown" foods are neither safer nor more nutritious than conventionally produced foods
4. No prescription pill can produce rapid or permanent weight loss.

This information is meant for normal healthy individuals. There are some cases where individuals do need vitamin supplements because of vitamin deficiencies. Your doctor will test for those if you are feeling fatigued or sick and in those cases they may help those individuals feel more energetic. From reading this textbook and my prior classes I've come to the conclusion that vitamins are simply a waste of your money unless a doctor tells you to take them.
