Drinking milk oatmeal every morning for a month, I believe the most obvious difference is that you can poop healthily every day, thanks to the role of oatmeal. Oats, as a kind of grain, are rich in dietary fiber, especially a bowl of milk oats every morning, which can promote gastrointestinal peristalsis and have a good regulatory effect on the stomach. At the same time, the inhibitory ability of oat is close to that of arbutin, a whitening agent commonly used in cosmetics at present, which shows that the whitening effect of oat extract is equivalent to that of arbutin, but the cost of oat extract is much lower than that of arbutin. In addition, oats contain a lot of antioxidant components, which can effectively inhibit the redox reaction in the process of melanin formation and reduce the formation of melanin. Oats and milk are both good calcium supplements, and the sleep quality will be improved when calcium is sufficient. To sum up, all the effects will develop in a healthy direction.
