Carbohydrate Calculator
This calculator can be used to estimate the carbohydrate you will need per day. Carbohydrates are not essential nutrients in humans. The body can obtain all its energy from protein and fats. However, the brain and neurons generally cannot burn fat and need glucose for energy. The Institute of Medicine recommends a minimum of 130 grams of carbohydrate per day, which is the average minimal usage of glucose by the brain.

By definition, carbohydrate or carb, is the organic compound consists only of hydrogen, oxygen, and carbon, with hydrogen and oxygen in the 2:1 ratio. Carbohydrate, protein, and fats are the most important nutrition for human being. One gram of carbohydrate contains around 3.75 Calories of energy (or 106 Calories per ounce). Carbohydrate can be classified into simple and complex. Foods high in simple carbohydrates include fruits, sugars, sweets and soft drinks. Foods made mainly from rice, wheat, corn, potatoes, and beans, such as breads, pastas, noodles, etc. are high in complex carbohydrates. Nutritionists generally recommend complex carbohydrates, and nutrient-rich simple carbohydrate food, such as fruit (glucose or fructose) and dairy products (lactose) for the bulk of carbohydrate consumption. Simple sugars such as candy and sugary drinks are generally not recommended.
Based on the effects on risk of heart disease and obesity, the Institute of Medicine recommends that American and Canadian adults get between 40-65% of dietary energy from carbohydrates. The Food and Agriculture Organization and World Health Organization jointly recommend that national dietary guidelines set a goal of 55-75% of total energy from carbohydrates, but only 10% directly from sugars (their term for simple carbohydrates).
