    Unhealthy diets are responsible for preventable deaths globally per year, more even than smoking tobacco, according to a major study.

“But the biggest problem is not the junk we eat but the nutritious food we don’t eat,” say researchers, calling for a global shift in policy to promote vegetables, fruit, nuts and beans. While sugar and trans-fats are harmful, more deaths are caused by the absence of healthy foods in our diet. Heart attacks are the main diet-related causes of death, followed by cancers and diabetes (糖尿病).

The study found that eating and drinking better could prevent one in five deaths around the world. “Rather than trying to persuade people to cut down on sugar, salt and fat, which has been the main focus of diet policy debate in the past two decades, it would be better to promote healthy options. Adoption of diets emphasizing beans and other healthy plant sources of protein, for instance, will have important benefits for human health,” note the researchers.

The study is the most comprehensive analysis on the health effects of diet ever conducted. It looked at 15 different nutrients, giving detailed knowledge of the analysis and summary of the risk factors of them.

Tom Sanders, a professor of nutrition and dietetics (饮食学), said the analysis put too much emphasis on individual components rather than the overall diet. “Overweight is a major driver for risk of diabetes as well as cancer and the health evidence for this relationship is strong. Overweight is caused by eating more food energy than required rather than specific dietary components such as sugar. The trend for populations to sit too much is a major reason why there is an imbalance between energy intake and consumption but Increased availability of foods with high calories makes it too easy to overeat.”
