Eating More Whole Grains May Help Protect Your Heart

A comprehensive study published in the scientific journal European Heart Journal suggests that a small dietary change may lead to meaningful improvements in health. According to the findings, adding whole grains to the diet can provide significant protection for heart health and may help balance blood sugar and cholesterol levels.

A new analysis of dozens of studies conducted over recent decades examined how whole grain consumption affects the body at the molecular level, as well as the quantity needed in order to see a difference. The findings indicate that health benefits may begin with a daily intake of about 90 grams, or three servings. This is roughly equivalent to two slices of whole wheat bread and one bowl of oatmeal.

Researchers found that those who consumed three to six servings of whole grains per day showed improvements in a range of health measures, including blood pressure, body weight, waist circumference, and levels of LDL, often referred to as “bad” cholesterol.

Dagfinn Aune, a researcher in the Department of Epidemiology and Biostatistics at Imperial College London’s School of Public Health, explained the significance of the findings. He noted that there is a strong likelihood of a causal effect from whole grain consumption, which could contribute to a reduced risk of cardiovascular disease.

Whole grains such as oats, brown rice, whole wheat bread, and quinoa contain all parts of the grain kernel as they occur naturally. This is in contrast to refined grains, which undergo processing that removes important vitamins and dietary fiber.

Still, experts emphasize that whole grains are not a magic solution and changing just one component of one’s diet is generally not sufficient.

Alice Lichtenstein, a professor at Tufts University’s school of nutrition, explained in an interview with CNN that simply choosing a sweet pastry made with whole grains instead of a refined version may not provide a meaningful health benefit. She also warned that adding extra carbohydrates to the diet solely to reach a daily whole grain target could lead to weight gain.

Instead, experts recommend gradually replacing refined grain products with whole grain alternatives. When shopping, consumers are advised to turn the package over and check the ingredient list. The first ingredient should be a whole grain.

A gradual shift toward whole grain products, together with eating more fruits and vegetables and reducing the intake of sugar, salt, and saturated fat, is considered a safer and more effective approach to maintaining a healthy lifestyle and supporting heart health.
