A healthy diet is not too hard to comprehend: a little organic meat, with plenty of anti-oxidant rich organic vegetables, all cheaper than buying junk food, and the medical bills that comes from the ill health of a poor diet:

“A lot of people believe that having a healthy organic diet helps lower the risk of certain diseases. A recent study helped prove that claim, establishing that a healthy diet can lower the risk of cancer by as much as 65 percent. For lead author Dr. Ashish Deshmukh of the University of Florida, the findings of the study reveal it is important that a person’s total diet remain balanced, rather than focus on specific nutritional components. This means that a person’s diet should contain different nutrients derived from various sources, such as vegetables, fruits, and dairy. Aside from this, the food consumed should also be organic and should contain clean proteins, unprocessed carbohydrates, and non-toxic fats. The researchers arrived at this conclusion by assessing information from the Third National Health and Nutrition Examination Survey (NHNES III), which gathered data from almost 34,000 people from 1988 to 1994.

From the data pool, 1,200 participants were diagnosed with cancer at the time of the study. Those who participated in the survey kept a food diary where they tracked what they ate during the day. These documented diets were then ranked based on nutritional quality, following the dietary guidelines of the U.S. Department of Agriculture (USDA). The participants were then tracked for 17 years – during that time half of the initial respondents have already died. However, those who were able to maintain a balanced and nutritious diet had lowered their risk of dying early due to cancer and other causes by 65 percent, compared to those whose diets were considered to be of low nutritional quality.”

    This further confirms an already substantial body of knowledge that links a primarily vegetable diet (not necessarily vegetarian, but substantially vegetable based), with good health. With moderate exercise, sleep and reduced stress, you may even live as long as George Soros, if you want to.
