What is the decimal and fractional notation for percent based on a 2,000 calorie per day diet?
To determine the percents, they first determine how much of each listed item should be contained in a 2000-calorie diet. Then, they find what percent of that amount is contained in a serving of the food product being analysed. The recommended daily allowances are as follows (quoted from Wiki): “Food labeling reference tables Total Fat 65 g Saturated fatty acids 20 g Cholesterol 300 mg Sodium 2400 mg Potassium 2000 mg Total carbohydrate 300 g Fiber 25 g Protein 50 g (Based on a 2000 Calorie Intake; for Adults and Children 4 or More Years of Age)” If the Tostitos contain 9% of the daily allowance of fat, they must contain about 65*0.09 = 6 g of fat.
