This article correlates to a previous blog mentioning the "energy value" of food (fruits) taken directly vs. processed vitamins and that the material component isn't the only determinant but the "energy component" as well.
Notable quotes from the article include:
“We are not sure why this is happening at the molecular level but evidence shows that people who take more dietary supplements than needed tend to have a higher risk of developing cancer,” explains Byers, associate director for cancer prevention and control at the CU Cancer Center.
Byers’ research started two decades ago when it was observed that those who ate more fruits and vegetables tended to have less cancer. Byers and other researchers began investigating whether or not taking extra vitamins and minerals would reduce cancer risk even further.
“We found that the supplements were actually not beneficial for their health. In fact, some people actually got more cancer while on the vitamins,” says Byers.
"there is no substitute for good, nutritional food."
Again, the indians and the chinese got their medicine right. Unprocessed and alive.
