New study reinstates the health benefits whole grains have with new proof of their powerful influence in our system. By replacing refined grains with this healthier choice people will experience a calorie loss. This is possible due to the fact that calories are retained for a shorter period of time during digestion. Moreover, this whole food can help our body reach a more accelerated metabolism.
The American Journal of Clinical Nutrition published two studies that confirm the healthy benefits of whole grains. Until now, there were several complex epidemiology studies that showed that whole grains are related to a quality dietary fiber intake. This improves insulin sensitivity and confers better control over glycemic load. On the other hand, this type of foods has been subject to controversy as there weren’t any conclusive controlled metabolic studies yet.
As of recently, a new study dispels any doubt against the benefits of whole grains. Scientists conducted a comprehensive study that put participants under strict diet for an entire period of eight weeks. By studying these data, scientists are now able to explain how the consumption of these grains leads to weight management.
Phil J. Karl, the lead author of the study and also an alumnus of the Friedman School of Nutrition Science and Policy at Tuffs, explains why this study is different. This is the first time a scientific research is ample enough to shed light on how whole grains can result in improved health.
During the study, participants were encouraged to eat a whole grain diet that respected the recommended dietary allowance for fiber. As a result, all of them managed to get rid of 100 extra daily calories with ease. The results are similar to the ones registered by people who consume refined grains yet with low fiber intake. The effects on the metabolism influenced a greater resting metabolic rate together with increased fecal losses.
The study lasted for eight weeks during which 81 participants were given the same nutritious instructions. The only difference was the grain source alone. By the end of the study, the group that consumed whole grains lost the same number of calories as though they took a 30-minute walk. Thus, the whole food diet was more beneficial for the health of participants than the other types of nutritious habits. This is why it is important to consume whole grains regularly. Women are encouraged to eat at least three ounces of whole grains while men can eat four ounces on a daily basis.
