Nutrients that can provide calories in the diet are sugar (carbohydrate), fat, protein, alcohol, organic acids and so on. The calories they contain are: sugar (carbohydrate) 4 calories, fat 9 calories, protein 4 calories, alcohol 7 calories and organic acid 2.4 calories.
To calculate the calories contained in food or diet, we must first know the weight of calorie nutrients, and then use the following formula to calculate:
Calories (kilocalories) = grams of sugar ×4+ grams of protein ×4+ grams of fat ×9+ grams of alcohol × 7.
Humans have been studying and exploring for their own changes. Until the end of 19. Scientists all over the world have found that metabolic rate is directly proportional to the surface area of human body, and food has a special dynamic function, which proves that the law of conservation of energy is also applicable to human body, and has compiled a food calorific value table and energy conversion coefficient.
