Food Calorie Table:

Food Calorie Table is a list of food calories drawn or listed according to the energy contained in a unit amount of food (e.g., 100 grams) for ease of reference in dietary care. Different foods produce different amounts of energy.

For people with chronic diseases such as obesity, diabetes, and hypertension, controlling the amount of energy consumed by the body each day is a way to reduce their own morbidity. Therefore, it is necessary to measure the energy content of each food for patients to calculate or organize the total **** energy content of the food they eat at each meal.

The number of calories a normal person needs each day is related to his weight. The relationship between hourly calorie intake and body weight is about 1 kcal/hour/kg or 4.186 kJ/hour/kg. So the normal average daily calorie requirement for an adult weighing 50 kilograms is as follows:

Average calorie requirement = 4.186 kilojoules * 24 hours * 50 kilograms = 5023.2 kilojoules

On average, for every kilogram of body weight gained, the calorie requirement of the body increases by 0.1 MJ. Generally speaking, an adult man requires about 9.25 to 10.09 million joules of calories per day; an adult man needs about 9.25 to 10.09 million joules per day. In general, an adult man needs about 9.25 to 10.09 MJ per day; an adult woman needs about 7.98 to 8.82 MJ per day.

The average elementary school student needs about the same amount of calories as an adult male, about 9.25 megajoules per day. Secondary school students are developing, so they need to consume more calories, with boys needing an average of 10.465 megajoules per day and girls needing 10.046 MJ.
