We have heard for years that eating a well-balanced diet will have positive health benefits. Now, three decades of data demonstrate that healthy eating patterns reduce heart disease (JAMA Internal Medicine, online June 15, 2020).

Following Healthy Eating Patterns:

The investigators drew their data from three different cohorts. They are the Nurses’ Health Study, Nurses’ Health Study II, and Health Professionals Follow-up Study (165 794 women and 43 339 men). Every few years, the volunteers filled out extensive dietary questionnaires and responded to surveys about their health status.

To analyze this treasure trove of information, the researchers used several previously validated ways of scoring healthy eating patterns. These included the Healthy Eating Index-2015, the Adapted Mediterranean Diet score, the Healthy Plant-Based Diet Index or the Alternative Healthy Eating Index.

People who scored higher on any of these scales were almost 20 percent less likely to suffer a heart attack or a stroke. The investigators note that these different dietary indexes were not perfectly correlated with each other. Presumably, they measure slightly different aspects of a good diet. Nonetheless, the general direction was consistent. Clearly, people eating better diets are less likely to suffer cardiovascular problems.

The scientists conclude

“Our findings provide support for the recommendations of the current Dietary Guidelines for Americans that it is not necessary to conform to a single dietary plan to achieve healthy eating.”

People can adapt these plans to suit their personal preferences and food traditions. Choosing less processed food and more whole grains and vegetables is a common thread.
