Eggs are not high in calories, containing about 138 calories per 100 grams. A typical egg of about 60 grams yields about 80 calories. The basic nutrition of eggs contains mainly protein, followed by fat and a little carbohydrate. Every 100 grams of eggs contains about 12 grams of protein, 9 grams of fat, and 1.5 grams of carbohydrates. Eggs are a better food choice because on the one hand they are not high in calories and on the other hand they are more nutritious. It is worth mentioning that the number of calories produced by eggs is also affected by the way they are cooked. Boiled eggs, egg custard or egg flowers produce relatively few calories. But fried eggs, scrambled eggs will produce high calories, mainly because the cooking oil will also produce part of the heat, which will lead to an increase in food calories, so the control of calories must pay attention to the cooking method.
