American Diets Are a Little Better Now

Over the last decade and a half, American diets have improved, but the changes are modest. More of us should be eating whole grains and protein from plants.

Public health experts have long been concerned that common American diets are contributing to obesity and chronic diseases such as diabetes, heart disease and cancer. As a result, they do their best to offer guidelines on what diets to follow. How are we doing?

Are American Diets Improving?

Despite lots of information about how to eat healthfully, Americans are still getting too much of their energy from low-quality carbohydrates. Nutrition scientists drew this conclusion from analyzing Nutrition Health and Examination Survey (NHANES) data from 1999 to 2016 (JAMA, Sept. 24, 2019).

Although American diets got a little better over that time frame, the change was quite modest. On the positive side, people consumed fewer calories from added sugar and from fruit juice. Liquid calories raise blood sugar quickly, but people may still be hungry after drinking soda or juice. Since added sugar has been a weakness of American diets for some time, reducing it is good news.

Other news is not as good. For one thing, Americans are still getting about 14 percent of their calories from added sugars. For another, only 9 percent of calories in a typical American diet come from whole fruits and whole grains. About 42 percent comes from highly refined grains, added sugar and starchy vegetables such as potatoes.

The scientists note that people may be eating fewer refined carbohydrates in response to changes in dietary guidelines away from low-fat diets and towards healthy fats and plant sources of protein. Popular diet trends such as the Paleo, Atkins, vegan and vegetarian diets may also be shaping American diets now. However, by far the most widely consumed sources of protein are red meat and processed meat. Relatively few people rely on seafood or plant sources such as whole grains, nuts, and legumes for their protein. In addition, poorer people are not eating better than they have in the past. Sadly, low-quality carbohydrates are cheap calories.

How Is the Healthy Eating Index?

The estimated Healthy Eating Index went from 55.7 to 57.7. Although this change is statistically significant, it leaves plenty of room for improvement.
