I believe everyone has a certain understanding of sweet potato and purple potato, and many people are very familiar with these two kinds of potatoes. In fact, purple potato is also a kind of sweet potato, but there are certain differences in color and taste between the two. Many people usually like to lose weight when it suits them, and there are many foods in our daily life that have the effect of losing weight. As long as we know more about this common sense and use these foods to lose weight, we can get nutritional intake.

1, sweet potato and purple potato are rich in starch, and the calories of these two foods are similar. For people who lose weight, they must control their calorie intake. If you have too many calories, it is likely to lead to obesity, so eat less starchy food.

2. Compared with sweet potato, the sugar containing starch is slightly weaker. For people who lose weight, if they eat purple potatoes and sweet potatoes for a long time, it is the government's, but it is relatively easy to lose weight directly, and sweet potatoes are rich in starch, which can be converted into glucose to provide energy for the human body, so it is better to stay away from sweet potatoes if you want to lose weight.

3. Purple sweet potato and sweet potato are rich in nutrition, and anthocyanins will still be found in the two foods. Anthocyanin is an antioxidant, which has a good effect on preventing many diseases and is helpful for treating cancer and cardiovascular diseases, so purple sweet potato has a stronger anti-cancer ability on sweet potato.

Purple sweet potato is rich in selenium and anthocyanin besides the nutrients of ordinary sweet potato. Anthocyanin can prevent and treat 100 diseases, and is known as the seventh essential nutrient after water, protein, fat, carbohydrates, vitamins and minerals.

Sweet potato/purple potato can replace staple food, but it can't be completely replaced, only partially replaced. Simply put, you can't just eat sweet potatoes/purple potatoes for a long time without eating rice noodles to lose weight. The best way to eat is to have half of the staple food and half of the coarse grains, which is what we often call "matching the thickness".
