Healthy Nutrition Pyramid- Watching your Plate?
A food pyramid or diet pyramid is a pyramid-shaped diagram representing the optimal number of servings to be eaten each day from the basic food. Food pyramid published by the WHO and FAO The World Health Organization, in conjunction with the Food and Agriculture Organization, published guidelines that can effectively be represented in a food pyramid relating to objectives to prevent obesity, chronic diseases and dental caries based on meta-analysis though they represent it as a table rather than a "pyramid".
The structure is similar in some respects to the USDA food pyramid, but there are clear distinctions between types of fats and a more dramatic distinction where carbohydrates are split on the basis of free sugars versus sugars in their natural form. Some food substances are singled out due to the impact on the target issues the "pyramid" is meant to address, while in a later revision, some recommendations are omitted since they follow automatically from other recommendations while other sub-categories are added. The reports quoted here explain that where there is no stated lower limit in the table below, there is no requirement for that nutrient in the diet.

To understand why to consider the determination of an amount of "10% free sugar" to include in a day's worth of calories. For the same amount of calories, free sugars take up less volume and weight, being refined and extracted from the competing carbohydrates in their natural form. In a similar manner, all the items are in competition for various categories of calories.
