“This study re-affirms previous work indicating a healthy diet includes limiting overly processed and refined foods,” Scott Lear, Pfizer/Heart & Stroke Foundation chair in cardiovascular rrevention research and health sciences professor said in a statement.
Harvard T.H. Chan School of Public Health says that whole grains are a better option than refined grains. The former provides full nutritional value while refined grains are emptied of their health benefits during their processing.
Reccomendations outlined in the 2020-2025 Dietary Guidelines for Americans state that on a 2,000 calorie diet, people should aim to consume 3 or more ounces of whole grains a day and less than 3 ounces of refined grains daily.
Examples of unprocessed whole grains include brown rice, wild rice, oats, corn and quinoa.
