Longevity
A 2015 analysis found that people who eat more whole grains tend to live significantly longer lives independents of other measured dietary and lifestyle factors - Harvard University's preeminent twin nutrition studies the Nurses' Health Study and the Health Professionals Follow-Up Study.
Prevent Chronic Diseases
Eating whole grains appears to reduce the risk of heart disease, type 2 diabetes, obesity,and stroke.
Out of Harvard: ""White rice, Brown rice, and risk of type 2 diabetes." Eating white rice was associated with a 17% greater rise of diabetes; replace it with other whole grains, such as barley and oats, the diabetes risk dropped by 36%.
Alzheimer's Disease
The consumption of animal-based products has been associated with the rise in Alzheimer's Disease or Dementia. On the other hand, diet rich in whole grain and other whole food has been linked to improve brain cognitively.
Arteries
Researchers at Wake Forest University followed 1,000 people for 5 years, and measured the amount of plaque in their carotid arteries. People who ate the most whole grains had significantly slower narrowing of two of the most important arteries that feed the heart and the carotid arteries that feed our brains.
Weight-Loss
Observational studies strongly suggest that those who consume three serving of whole grains a day tend to have a lower body mass index, less belly fat, less tendency to gain weight.
