Few studies have been conducted to determine whether greater adherence to the DGA’s recommended dietary patterns is related to a lower risk of total and cause-specific death over time. The researchers analyzed health data from 75,230 women in the Nurses’ Health Study and 44,085 men in the Health Professional’s Follow-up Study obtained over 36 years. At the start of the trial, all patients were clear of cardiovascular disease or cancer, and they completed dietary questionnaires every four years.
Their data was graded using each of the four dietary pattern indices (Healthy Eating Index 2015, Alternate Mediterranean Diet, Healthful Plant-based Diet Index, and Alternate Healthy Eating Index). Key components shared by everyone include whole grains, fruits, vegetables, nuts, and legumes, however, other components vary across dietary patterns.

A higher score on at least one of the measures was linked to a lower chance of death from any cause, as well as from cardiovascular disease, cancer, and respiratory disease. Higher AMED and AHEI scores were related to a decreased probability of dying from a neurodegenerative illness. The findings were similar for non-Hispanic whites, non-Hispanic blacks, and Hispanics.
The current DGAs (2015-2020) advocate for a variety of healthy eating patterns that can be tailored to individual dietary traditions and tastes. The US Departments of Health and Human Services (HHS) and Agriculture (USDA) issue an updated version of the Guidelines every five years.
“It is important to evaluate adherence to DGAs-recommended eating patterns and health outcomes, including mortality, so that timely updates can be made,” said Hu. “Our findings will be valuable for the 2025-2030 Dietary Guidelines Advisory Committee, which is being formed to evaluate current evidence surrounding different eating patterns and health outcomes.”
