“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.
