Researchers at the Harvard T.H. Chan School of Public Health have shown that adopting a wide range of healthy eating habits is associated with a lower mortality risk.
People who scored higher on at least one of four healthy eating patterns were shown to have a decreased risk of dying during the research period from any cause, as well as a lower risk of dying from cardiovascular disease, cancer, or respiratory illness.
These results are in keeping with the most recent version of the Dietary Guidelines for Americans, which promotes a wide variety of healthy eating styles.
This research was released online by JAMA Internal Medicine on January 9, 2023.
Whether or whether higher adherence to the DGAs-recommended dietary patterns is connected with long-term risk of total and cause-specific death has been the subject of few research. Study participants included 75,230 women from the Nurses’ Health Study and 44,085 men from the Health Professionals Follow-up Study, and data was gathered over a span of 36 years.
When the research began, no one in the group had ever been diagnosed with cardiovascular disease or cancer, and they filled out food-recording questionnaires every four years. Each of the four dietary pattern indices was used to provide a score to their responses .
The probability of dying too soon due to any reason, as well as due to cardiovascular disease, cancer, or respiratory illness, was lower among those with higher scores on at least one of the indices. The chance of dying from neurodegenerative illness was shown to be reduced in those who scored higher on the AMED and the AHEI. The findings held true across three racial groups: whites, blacks, and hispanics.
Current DGAs (2015-2020) provide a variety of healthy eating habits that may be modified to suit one’s cultural background and personal preferences. The Health and Human Services (HHS) and Agriculture (USDA) in the United States issue a new edition of the Guidelines every five years (USDA).
