It turns out birds aren't bird brains when it comes to what they eat. A number of species of birds have been shown to choose foods that contain higher levels of healthy things like protein and antioxidants and lower levels of not-so-healthy things like heavy metals and pesticides. Since they're such finicky eaters, scientists figured to let them choose between conventionally and organically grown food, and see which they deemed better for them. The vote was unanimous: birds prefer non-organic.

New research out of the Oregon Health and Science University may explain the discrepancy between the theory and reality of dieting. They found that, at least in some of our closest relatives, cutting calories isn't enough to lose weight because the body compensates for the reduced intake by lowering activity levels.

It would be great if we could just stop eating meat all together. But there's one problem - we need complete dietary protein, and about 60 grams a day of it. This is what I call the Protein Problem: the problem is that we need a lot of protein, nutritionally speaking, but producing it is an ecological nightmare. If you've read my post about why protein is so nutritionally important, you know that meat is simply the best source of complete dietary protein. But is becoming vegetarian and eating tofu the solution to our protein problem? Unfortunately, it's not that simple.

The public's biggest concern when it comes to GMOs is their safety. There are a lot of misconceptions about genetic engineering. When pressed on science of GMOs, I have often heard people fear that the genetically modified material in the foods they are eating will somehow mutate their DNA too. While logically it sounds like that makes a bit of sense, scientifically its nonsense. So how do we test for and ensure that GMOs are safe? Allow me to introduce you to the complex world of genetic technology regulation. Image credit: kevin dolley on flickr.

Why have the world's children ballooned over the past hundred years? (photo by photomequickbooth from flickr).
