Water, Turkey and Brain Myths Challenged Again

The NY Times “Well” blog is taking on “Medical Myths Even Doctors Believe.” Among them, we find that you don’t need eight glasses of water per day (you get enough water through the foods you eat and drinks like coffee, orange juice), dim light doesn’t ruin your eyesight (it just makes eyes tired) and shaving doesn’t cause hair to grow back more vigorously (we’ve actually known that since studies on the subject in 1928).

So why do these myths persist? The Times doesn’t get into that, but I’d guess they nag on because they seem to make so much sense. And often times, there’s a kernel of truth in there that buoys the nonsense.

For example, the Times tackles the myth of turkey making you drowsy (
which we’ve discussed in this blog previously). Sure, you get tired after eating turkey. But think of the times you normally eat it. Holiday meals, right? It’s not the turkey it’s the tremendous amount of energy your body needs to focus on digestion that’s making you tired.

In the Times article, they explain there’s just as much tryptophan in turkey as beef or chicken. Also, there’s more of the amino acid in cheese and pork.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
