Could something as simple as adding more whole grains to your diet help support better heart health?
New research suggests it may.
A large systematic review and meta-analysis combining 87 clinical trials found that eating whole grains was associated with improvements in several important cardiovascular risk factors, including body weight, waist circumference, blood pressure, cholesterol, blood sugar and triglycerides.
How Much Could Make a Difference?
Researchers found that many of the benefits appeared around four to six servings of whole grains per day, although the optimal amount varied depending on the individual health measure being examined.
Whole-grain foods include options such as oatmeal, whole-grain bread, brown rice, barley and other grains that retain more of their natural structure than refined grains.
Why Whole Grains?
Unlike refined grains, whole grains retain the bran, germ and endosperm.
That means they generally provide more fiber and a broader range of nutrients. Researchers have long studied whether replacing refined carbohydrates with whole grains can contribute to better cardiovascular and metabolic health.
The new analysis strengthens that evidence by combining results from dozens of randomized clinical trials rather than relying on a single study.
It’s Not a Miracle Food
The findings don’t mean eating whole grains alone will prevent heart disease.
Overall diet, physical activity, smoking, genetics and other health factors can all influence cardiovascular risk. Individual dietary needs can also differ.
But the research suggests that choosing whole-grain foods more often could be one practical part of a heart-healthy eating pattern.
