According to the research, the latter contains more dietary fiber, vitamins, minerals, and fatty acids than refined grains.
For 9.4 years, scientists have observed 137,130 people aged 35 to 70 years. The results showed that those who ate 359 or more grams of refined grains per day had a 27 percent higher risk of death and a 33 percent higher risk of heart disease.
