The new research suggests eating three portions of Whole Grains a day could help reduce your waist size, blood pressure and blood sugar levels. The study of middle to older-aged adults found that eating foods such as whole-grain bread, rolled oats, cereal or brown rice may also protect against heart disease.
Researchers at Tufts University in Massachusetts looked at how eating whole and refined grains for 18 years impacted five risk factors of heart disease, Waist size, blood pressure, blood sugar, triglyceride, and HDL cholesterol.
According to the Dietary Guidelines for Americans 2020-2025, the recommended amount of Whole Grains is three or more servings daily. There are no official guidelines on whole grain food in the UK although experts say the public should aim for at least three portions a day.The results showed that for each four-year interval waist size increased by an average of over 1 inch in the low intake participants compared to 1/2 an inch in the high intake participants. Even after accounting for changes in waist size, average increases in blood sugar levels and blood pressure were greater in low intake participants compared to those eating more whole grain.
