The Institute of Medicine recommends that people get an average of 130 grams of carbohydrates each day. The amount is different based on an individual's weight, gender, physical activity and caloric requirement. Carbohydrate intake should vary between 45 and 65 percent of the daily caloric intake.
Carbohydrates are an essential part of a healthy diet. Too little carbohydrate intake can result in several negative consequences including dizziness, fatigue, nausea and headache. Nutrition experts make the distinction between good and bad carbs. Good carbs are those sourced from whole grain foods, while bad carbs are found in refined foods that contain high amounts of sugar. Refined carbs should be limited.
