Which foods are perfect? Hint: Eat your broccoli
Here's a little tidbit I learned while perusing the September 2008 issue of National Geographic -- an article titled Shopping By The Numbers talks about a a food rating system called the Overall Nutritional Quality Index. Developed by researchers at Yale University and coming soon to a grocery store near you, the qualification system will rate foods on a scale of one to 100 -- one being the least nutritious and 100 being the most nutritious. In NG's list of common foods, only four items scored 100 -- blueberries, oranges, green beans and broccoli. Here are some other ratings:
- Banana - 91
- Non-fat milk - 91
- Oatmeal - 88
- Raw almonds - 82
- Pasta - 50
- Vanilla yogurt - 43
- Skinless chicken breasts - 39
- Bagel - 23
- Hot Dog - 5
- Soda - 1
Are you killing coral reefs with your sunblock?
Sustainable Community, Celebs & Entertainment, Reviews & Products, Alternative & Green Health
The Environmental Health Perspectives journal recently published a paper claiming that certain ingredients in sunscreen are killing coral reefs. National Geographic, among others, picked up on it, and now beach-goers the world over are worried that the sunscreen they use to protect their skin is damaging coral reefs.
The Beauty Brains were asked about this last week, and they broke the issue down into an easy-to-understand format, explaining exactly what the concern was (certain chemicals found in sunscreen can cause bleaching in the reefs). The fact is that, yes, there are chemicals found in sunscreens that are detrimental to the environment, but the quantities listed in the paper failed to take a number of factors into account, such as those same chemicals being present in pollution as well as in sunscreen.
Their final opinion was that sunscreen use is not likely as big a culprit in the death of coral reefs as the paper indicates. However, if you're concerned because you swim near reefs (or just because you don't want to use sunscreen that could be damaging to the environment), you can look for natural sunscreens, or look out for the ingredients The Beauty Brains list as problematic.
