There may be some misunderstanding about blood sugar: “Eating any food that contains carbohydrates and sugars will cause blood sugar to rise”, and tomatoes are naturally no exception to this concept: the glycemic index (GI). When you look at a food and think about whether a diabetic can eat it, you have to take a step back and think about the question: How much of a blood sugar reaction will it cause when you eat it? The amount of this glycemic response is the glycemic index, and we distinguish foods with values based on the standard of how much sugar is raised by different foods, less than 55 is low GI food, between 55 and 70 is medium GI food, more than 70 is high GI food, and tomatoes do not belong to high GI food, in the category of edible. Tomatoes are both a vegetable and a fruit and can be consumed by diabetics even if their blood sugar is not well controlled. But we must emphasize some other possibilities, please pay attention! 1, first of all, the amount of consumption, tomatoes can indeed be eaten, but not eat more. 2, tomatoes with the daily processing, pay attention to the ingredients, for example, sugar mixed tomatoes, please be careful. Tomatoes can be eaten, but you eat its nutrition? Suggestions: black tomatoes > small tomatoes > larger tomatoes > larger tomatoes > smaller tomatoes The nutrition of tomatoes is known for being rich in vitamin C and lycopene, the red or yellow color of tomatoes is mainly produced by lycopene, different varieties of tomatoes have different contents of these two ingredients. Small tomatoes contain more vitamin C and lycopene than large tomatoes, and not only that, small tomatoes contain more minerals such as potassium, calcium, and selenium than large tomatoes. Therefore, compared to large and small tomatoes, small tomatoes have higher nutritional value. However, for diabetics, the sugar content of small tomatoes is higher than that of large tomatoes, but compared to other fruits, the sugar content of small tomatoes is also acceptable. Therefore, diabetics can also use small tomatoes with confidence, as long as they do not eat too much. Also for large tomatoes, the darker the color, the higher the nutritional value. Small tomatoes sold in the market are also available in dark red and light red, the darker the color, the higher the nutritional value. There is also a rare black tomato, which is rich in anthocyanins, a strong antioxidant, and relatively high in vitamin C and lycopene, making black tomatoes more nutritious. How to get the most out of tomatoes Raw tomatoes can retain the maximum amount of vitamin C, dietary fiber, and lycopene cannot be absorbed well. Cooked tomatoes, in which lycopene can be well utilized by the body, but the amount of vitamin C and dietary fiber will be reduced.
