Eating more plant foods may lower heart disease risk in young adults, older women

Eating more nutritious, plant-based foods is heart-healthy at any age, according to two research studies published in the Journal of the American Heart Association, an open-access journal of the American Heart Association.
In two separate studies analyzing different measures of healthy plant food consumption, researchers found that both young adults and postmenopausal women had fewer heart attacks and were less likely to develop the cardiovascular disease when they ate more healthy plant foods.
The American Heart Association Diet and Lifestyle Recommendations suggest an overall healthy dietary pattern that emphasizes a variety of fruits and vegetables, whole grains, low-fat dairy products, skinless poultry and fish, nuts and legumes and non-tropical vegetable oils. It also advises limited consumption of saturated fat, trans fat, sodium, red meat, sweets and sugary drinks.
One study, titled “A Plant-Centered Diet and Risk of Incident Cardiovascular Disease during Young to Middle Adulthood,” evaluated whether long-term consumption of a plant-centered diet and a shift toward a plant-centered diet starting in young adulthood are associated with a lower risk of cardiovascular disease in midlife.
“Earlier research was focused on single nutrients or single foods, yet there is little data about a plant-centered diet and the long-term risk of cardiovascular disease,” said Yuni Choi, Ph.D., lead author of the young adult study and a postdoctoral researcher in the division of epidemiology and community health at the University of Minnesota School of Public Health in Minneapolis.
“A nutritionally rich, plant-centered diet is beneficial for cardiovascular health. A plant-centered diet is not necessarily vegetarian,” Choi said. “People can choose among plant foods that are as close to natural as possible, not highly processed. We think that individuals can include animal products in moderation from time to time, such as non-fried poultry, non-fried fish, eggs and low-fat dairy.”
Because this study is observational, it cannot prove a cause-and-effect relationship between diet and heart disease.
The researchers believe the results highlight possible opportunities to lower heart disease by encouraging people to consume more foods in the Portfolio Diet.
“We also found a dose response in our study, meaning that you can start small, adding one component of the Portfolio Diet at a time, and gain more heart-health benefits as you add more components,” said Andrea J. Glenn, M.Sc., R.D., lead author of the study and a doctoral student at St. Michael’s Hospital in Toronto and in nutritional sciences at the University of Toronto.
Although the study was observational and cannot directly establish a cause-and-effect relationship between diet and cardiovascular events, researchers feel it provides a most reliable estimate for the diet-heart relation to-date due to its study design (included well-validated food frequency questionnaires administered at baseline and year three in a large population of highly dedicated participants). Nevertheless, the investigators report that these findings need to be further investigated in additional populations of men or younger women.
