A Swedish study published in July of 2013 in the American Journal of Clinical Nutrition on 71,000 people aged 45-83 followed for 13 years showed that people who eat no fruit of vegetables die about 3 years sooner. People eating even one serving fruits and veggies lived 19 months longer.
People eating less fruit and veggies were more likely to smoke and consumed more red meat, high-fat dairy, sweets, and snacks.
