For some people, this is not necessarily a misconception, because they do eat mostly coarse grains. However, for some people, especially newly diagnosed diabetic patients, they do not love to eat coarse grains, but are afraid to eat fine grains, often told the doctor unusually nervous: “I have not eaten fine grains for three months, all corn flour, corn ballast, buckwheat noodles, oat noodles, eat my eyes are blurry”. These patients believe that as soon as they eat fine grains of high blood sugar, so they dare not eat. In fact, the thing to eat, blood glucose, that does not mean that you should not eat, but only that you have to eat and have to think of another way. Fine grains contain less fiber, digestion and absorption is faster, blood sugar is bound to rise faster. In fact, fast digestion and absorption also has benefits: old and weak, poor digestion, eat fine grains but beneficial to the body. For such people, eating coarse grains can not be absorbed, but also make the stomach uncomfortable, and may be due to indigestion, lack of energy and affect the state of health. Therefore, to consider the coarse and fine with, for example, a coarse food with two to three fine food, can be eaten in accordance with this ratio in a meal, but also three meals a coarse food a fine food alternately. Wearing clothes is about mixing and matching, so is eating. In addition, the combination of coarse and fine should also take into account the patient’s physique. For people with poor body condition and thin body shape, eat less coarse grains; while for obese and fit people, you can slightly increase the proportion of coarse grains. In addition, eating more vegetables is also a way to increase dietary fiber, not just eating coarse grains to increase fiber.
