Fruits and vegetables are two ingredients for a great diet. That's a no brainer. But if you eat more, as researchers from Imperial College London found, your chances of living longer increase drastically. Researchers estimated that 7.8 million premature global deaths could be avoided yearly Per the researchers, 10 portions is 800 grams of fruits and vegetables a day. If people ate up to 10 portions a day, there would be a 24 percent lower risk of heart disease, 33 percent lower risk of stroke, 28 percent lower risk of cardiovascular disease, 13 percent lower risk of cancer, and a 31 percent lower risk of dying early when compared to not eating any fruit or vegetables.
