Yam is not a carbohydrate, but the main nutrients in yams are carbohydrates. Carbohydrates are generally referred to as carbohydrates. Carbohydrates are a pure substance, but yams are a food, a mixture that contains numerous nutrients. One of the main nutrients in yam is carbohydrates. Each 100 grams of yam contains 57 calories, including 12.4 grams of carbohydrates, 1.9 grams of protein, 0.2 grams of fat, 5 milligrams of vitamin C, and 16 milligrams of calcium. Also, yams contain other minerals and vitamins such as sodium, iron and magnesium. As you can see, yams also get their calories from carbohydrates. Moderate consumption of yams can provide the body with calories and nutrients, but if excessive intake, it will lead to excessive carbohydrate intake, which can lead to obesity and other health problems. Therefore, it is recommended to consume yam in moderation. Diabetic patients who consume yam should reduce the intake of other staple foods accordingly, so as not to affect blood sugar. Yam is recommended to be consumed together with other protein-rich foods, such as beef and eggs, to achieve a balanced nutrition.
