Final answer:
The recommended daily intake of CHO grams is about 130 grams for individuals up to the age of 13, based on a 2,000 calorie diet. Carbohydrates should be supplemented with proteins, vitamins, and fats.
Step-by-step explanation:
The recommended daily intake of CHO grams varies depending on factors such as age, sex, activity level, and overall calorie needs. According to the information provided, up to the age of 13 years, it is recommended to consume about 130 grams of carbohydrates per day. Most of these carbohydrates should be complex, as they provide energy for a longer period of time and more steadily.
It is important to note that this recommendation is based on a 2,000 calorie diet, and individual needs may differ. The information provided does not give a specific value for CHO grams for individuals beyond the age of 13 or provide a breakdown based on sex, activity level, or other factors.
To ensure a well-balanced diet, it is also advised to supplement carbohydrates with proteins, vitamins, and fats. Carbohydrates provide 4.3 kcal/g, while fats provide 9 kcal/g.
