The consequences of not eating a balanced diet may be much graver than we thought.

A major study published in the Lancet this month suggests it contributes to one in five deaths worldwide. That’s about 11 million deaths every year that may be prevented by eating fewer red and processed meats, sugary drinks and trans fats — and more whole grains, nuts and fruit.

The seven-year Global Burden of Disease Study looked at dietary factors from 1990 to 2017 in 195 countries and found people were eating too many of the wrong types of food, and too little of the food their bodies needed. And that may be a key factor in a range of chronic diseases.

"This study affirms what many have thought for several years — that poor diet is responsible for more deaths than any other risk factor in the world," study author Christopher Murray of the University of Washington noted in a release.

"While sodium, sugar, and fat have been the focus of policy debates over the past two decades, our assessment suggests the leading dietary risk factors are high intake of sodium, or low intake of healthy foods, such as whole grains, fruit, nuts and seeds, and vegetables.”

The study tallied 10 million deaths linked to cardiovascular disease, with cancer, at 913,000, coming in a distant second. Type 2 diabetes accounted for 339,000 deaths.
