Personally....I smell a rat. We all know that a healthy diet is important but they cannot even agree on what a "healthy diet" is. Layer that with how our food is grown and processed, it's not what our grandparent ate. Genetically modified, corn/grain fed cattle and poultry, antibiotics, growth hormones, etc. Our environment has been so compromised and we are exposed to more toxins than ever before.

Only thing this study took into account was the age and weight of the person. We all know there are so many other factors involved.
