Scientific diet is the basis of diabetes treatment, but for many diabetics, eating sweets is not a “no-go” area. The so-called “sweets” are foods that contain a lot of sucrose and glucose, such as glucose water, brown sugar water, cane sugar, ice cream, chocolate, mooncakes and various sugary drinks. After eating these foods, sugar will be quickly absorbed by the body, blood sugar rises steeply and will last for a while. The food we usually eat, such as rice, noodles and steamed buns, are starchy foods and belong to polysaccharide, which are gradually digested and absorbed in the gastrointestinal tract, causing a much lower rise in blood sugar than eating the same amount of sweet food. In the case of stable blood sugar, it is possible to eat some sweets in moderation. This requires attention to firstly, what to eat, secondly, how much to eat and thirdly, when to eat. Different sweets contain different amounts of sugar, which requires calculating the calories contained, taking care to subtract them from the main food. For example, one apple produces about the same amount of calories as one tael of rice. Therefore, the amount eaten at one time should not be much, such as only 1-2 slices of watermelon or half an apple at a time. As for the time to eat, it is recommended to eat between two meals, such as 10:00 am and 3-4:00 pm. Eat a little less main food and a little sweet food with meals, so that the blood sugar after meals is not too high, but also not to have hypoglycemia before meals. For people who monitor their blood sugar significantly higher after eating sweets, it means that it is not suitable to eat this kind of food, or the amount is too much. For diabetics who want to eat dessert there is another way, which is to use sweeteners instead of sugar. There are two types of sweeteners in common use: one is artificial sweeteners containing only a trace of heat or no heat, including saccharin, aspartame, meringue, stevioside; the other is artificial sweeteners containing a certain amount of heat, including xylitol, sorbitol, maltitol, fructose, lactose and so on. Because their metabolic process is different from sucrose, so diabetics can also eat in moderation. It should be noted that foods with added sweeteners are not really the same as “sugar-free” and should not be eaten in excess. For example, “sugar-free moon cake”, although it does not contain sucrose, but its main components are starch and lipids, which can produce high calories, after eating will significantly increase blood sugar, do not let go of consumption.
