2000 Calories Diet and Recommended Daily Dose

The 2000 calories diet is a reference for daily caloric intake on average. But how do you calculate the daily calorie requirement? Diet 2000 calories . The number of calories we need daily varies, of course, by gender, age, height, body type, environment, lifestyle, and general health. Therefore, not all of us need the same number of calories. The problem occurs when the calorie value of foods, and especially% RDD, that is, the percentage provided by the * Recommended Daily Dose, is passed on the labels.

On some labels we also find the formula% DRV * Daily Reference Value or, most often,% DRQ or DEQ * Daily Estimated Quantity.

This 2,000-calories standard comes from the U.S. Food and Drug Administration (FDA) to include nutrition labeling on packaged foods. Introduced in 1990, the Nutrition and Labeling Act was designed to standardize food labeling that was under the freedom of action of manufacturers and each American state. The demands of federal labeling of food consist in the fact that producers must specify a list of information such as ingredients, calories and portion size. [source: FDA].

These labels also allowed consumers to compare the amounts of saturated fat and sodium, in addition to vitamins and minerals, with “daily values”, which is the maximum amount recommended per day. Before establishing the FDA labels, there was no standard caloric intake that would remain the same for each consumer, making the recommended daily amount difficult to establish.

FDA was aware that the caloric requirements vary according to gender, age, and physical activity level, but it was also known that it would take up a lot of space on the label to specify all the daily values ​​needed for each different category of consumers. So the FDA turned to the USDA surveys on food consumption, which reported caloric intake for men, women and children.

According to research, men consume between 2,000 and 3,000 calories per day, women between 1,600 and 2,200, and children consume between 1,800 and 2,500 calories daily. To simplify labels on food, the FDA has proposed using a single value on all labels: 2,350 calories per day.

Although more studies have shown that most men and women need more than 2,350 calories each day, establishing this value as a standard has been met with criticism by those who thought it would result in overeating or ignoring the standards. Thus, the formula has been simplified by including daily values ​​as percentages based on a diet of 2,000 calories.

FDA came to the conclusion that this optimal and rounded number was more effective in educating the population. In addition, it reflects the caloric requirements for postmenopausal women, viewed as a predisposed fattening population.

To assess the calorie requirement, the FDA knew that the calorie value of 2,000 should be adjusted to age, gender and physical activity level. It is still debatable whether this responsibility lies with the general population. Thus, although a diet of 2,000 calories may be ideal for some of us, it clearly does not work just as well for everyone.

A kilocalorie is the amount of energy required to raise the temperature of a quantity of water. Kilojoules are the energy the food gives, 1kcal equivalent to 4.184 kj. In normal speech, we express ourselves in calories, and when reading on labels the number of kcalors we can equate to calories. Is the same thing.
