This is the "five-second rule": if you are quick to raise the fallen food, we can assume that it does not fall. It turned out that all of this - another myth.

8. Sugar makes kids hyperactive

In American movies are often shown as the caring mother try not to give their children sweets with sugar and do not feed the sweet, because the children are insane. In fact, numerous studies have tried to find a link between hyperactivity and the use of sugar, but have not been able to do so.

Probably this myth originated in 1974, when Dr. William Crook (William Crook) wrote a letter to the American Academy of Pediatrics (American Academy of Pediatrics), which then published it. "I began to realize that sugar is the main cause of hyperactivity Over the last three years", - stated in the letter.

Consequently, the muscles will come less blood, the risk of seizures will increase significantly.

But at the moment there are no evidenceBased on scientific research to support this theory. And there are no sources have documented that people drowned from seizures related to swimming on a full stomach.

Cramps - frequent enough phenomenon in sailing time, and they have nothing to do with that, you do it on an empty or full stomach.
