Diabetics adopting a correct diet during the sugar control process is not only conducive to controlling postprandial blood sugar levels, but also stabilizing blood sugar fluctuations throughout the day. It can not only avoid the rapid rise of blood sugar concentration half an hour to one hour after a meal, resulting in an excessively high postprandial peak value, but also reduce the postprandial hypoglycemic insulin demand, thereby reducing the burden of islet secretion and release, without affecting the blood sugar 2 hours after a meal Up to standard.
< span> The blood sugar level 2 hours after the meal should be controlled within the standard range, but it is also necessary to pay attention to the fluctuation range of the blood sugar concentration from before the meal to after the meal. For example, the blood sugar level on an empty stomach or before a meal is 4.8, but the peak value appears as high as 11 half an hour to one hour after the meal. Even if the blood sugar is reduced to below 8 through exercise and other measures 2 hours after the meal, this level of blood sugar control is also There is a problem, because the maximum fluctuation of blood sugar before and after meals has exceeded 6 points, such a large fluctuation of blood sugar will cause a great burden on the islets, which is not only not conducive to the stable control of blood sugar in the future, but also easily leads to cardiovascular and neurological damage. damage and disease occur.
There are also sugar friends with fasting or pre-meal blood sugar Not high, the peak value is not high half an hour to one hour after a meal, the blood sugar level is not high 2 hours after a meal, and the blood sugar fluctuation within 2 hours after a meal is not large. However, during the random monitoring of blood sugar, it was found that the blood sugar level did not continue to drop 3 hours to 4 hours after the meal, but continued to maintain a high level, even higher than the first or second meal. (Some sugar lovers may be curious about blood sugar levels at other times, or have some bad performance caused by high blood sugar, so they will test random blood sugar 3~4 hours after meals)
If there is such a delay in post-meal blood sugar peak or post-meal blood sugar can not fall normally, such as meal two is higher than meal one, meal one and meal two Normal, three meals and four meals do not drop but rise, etc. In terms of diet, the following aspects should be considered:
1. The protein intake in the diet is too high, such as eating too much meat, soy products, etc. Even if you don’t eat much staple food, the blood sugar level will not be high within 1 hour after the meal, but it may cause the peak to appear 2 hours after the meal or be delayed to a longer time, and the peak will not appear until 3 to 4 hours after the meal .
This is because the gluconeogenesis of protein is converted into glucose, and the effect of raising blood sugar reaches its peak 2 hours after a meal, and the time of effect is affected by raising blood sugar before and after a meal Up to 4~5 hours.
Sugar lovers should know that although high-protein meat foods The content is extremely low (negligible to zero), but protein will also be converted into glucose through gluconeogenesis to raise blood sugar.
2. The fat intake in the diet is too high, For example, the amount of cooking oil is large, and the fat content of the ingredients is relatively high High, especially when eating fried and fried foods, oily nut foods, biscuits and crisp bread, etc., as well as eating too much meat, not only the protein is easy to be excessive, but also the fat is easy to be excessive. Pure lean meat The fat content is not low, let alone fat.
The effect of fat on blood sugar is similar to that of protein mentioned above, but the peak and duration of the effect on blood sugar are different. The effect of fat on blood sugar The effect lasts longer.
3. Promote meat when eating Vegetarian mix, a reasonable combination of carbohydrates, protein, fat intake ratio, the right amount of fat and protein can not onlyIt makes food more flavorful and nutritious, and can also delay the decomposition and absorption of carbohydrates. It can not only avoid high blood sugar peaks after meals, but also stabilize subsequent blood sugar levels through slow and continuous gluconeogenesis.
However, in the case of excessive intake of protein and fatty foods, it will have a counterproductive effect, especially affecting the Blood sugar, even if the blood sugar value is not high in the first 2 hours after a meal, the blood sugar will rise abnormally later.
