To reduce risk of colon cancer, head south

When you live in a sunny climate (like I do), your risk of colon cancer and other cancers drops. Scientists from Johns Hopkins University credit this phenomenon to possibility that greater serum levels of vitamin D is responsible. But don't start thinking of joining me in Arizona just yet. Skin cancer risk skyrockets here.

Ketosis, methylglyoxal, and accelerated aging: Fact or fiction?

Ketosis is a state typically associated with very low carbohydrate diets, such as the Atkins diet. In this state, the liver produces ketones based on fat (body fat or dietary fat). Unlike fats, ketones are water soluble and used by many tissues (including brain tissues) as a source of energy. Unlike glucose and lipoprotein-bound fats (in VLDL, for example), unused ketones cannot be converted back to substances that can be stored by the body. Thus excess ketones are eliminated in the urine; leading to their detection by various tests, e.g., Ketostix tests. This elimination of unused ketones in the urine is one of the reasons why very low carbohydrate diets are believed to lead to enhanced body fat loss. From an evolutionary perspective, one could argue that a ketosis state that involves the elimination of ketones in the urine is an inefficient and unnatural emergency mechanism. For our Paleolithic ancestors, dying of starvation was a much bigger problem than dying of obesity complicatio...

When I did the Jamie Eason 12-week trainer, one thing she recommended was drinking a protein shake within 30 minutes of working out to aid in muscle growth and recovery.  I do this pretty religiously, making my shake as soon as I get home or ordering one at the gym if I'm not coming straight home after my workout.  Protein is essential for muscle development and recovery, but you can get the adequate amount from whole foods, like meat, fish, beans, egg whites, nuts, and milk too. I'm usually a protein powder plus water and a few ice cubes kind of girl, but lately I've been trying more fresh fruit and veggie smoothies (with protein powder).  The other day, I added about 6 ounces of Odwalla Superfood drink to my protein powder and it tasted so good.  Although Odwalla is made with all natural ingredients, the calorie content and sugar is high, so I'd use it sparingly.  Mixed frozen bagged fruit is usually what I use. Since I don't like a huge shake (it feels so da...
