Researchers created models to estimate the percentage of US cardiometabolic deaths (deaths from heart disease, stroke, or type 2 diabetes), that can be attributed to speciﬁc aspects of a poor diet. After analyzing decades of eating pattern data from large, nationally representative surveys (NHANES), the researchers estimated that nearly half of all cardiometabolic deaths can be attributed to poor diet. Speciﬁcally, they found that high sodium diets, low nut & seed intake, high intake of processed meats (like sausage or bacon), low seafood omega-3 fats, low vegetable intake, low fruit intake, high intake of sugar sweetened beverages (like soda), and low intake of whole grains contributed the most to cardiometabolic deaths, at about 5.9-9.5% each. The researchers note that the importance of eating more healthy foods (like whole grains or vegetables) is very important, in addition to decreasing less healthy foods (like soda or bacon).
