Picture the fountain of youth made out of whole grains, fruits and vegetables. Study after study has shown that consuming these foods can lengthen your life-span. A recent JAMA Internal Medicine report found that each additional 28-gram serving of whole grains per day (go for nutrient-dense ancient grains like teff, amaranth, millet and sorghum) was associated with a 5% lower risk of dying from any cause. And in a study published in the American Journal of Epidemiology, European researchers have found that increasing your produce intake to more than 569 grams per day reduces your risk of mortality by 10%. Choose raw veggies whenever you can; in the same study, they were associated with a drop in mortality of 16%.
