Final answer:
The USDA recommends limiting fats and oils to 20-35 percent of daily calories, with saturated fats being less than 10 percent of daily calories to maintain a healthy diet.
Step-by-step explanation:
The USDA recommends limiting fats and oils to 20-35 percent of daily calories. However, it is important to understand the distinction between types of fats. Saturated fats should be limited to less than 10 percent of your daily calories, as per the nutritional guidelines, to maintain a healthy diet and reduce the risk of heart disease. Unsaturated fats, on the other hand, which are found in products like fish, nuts, and vegetable oils, can be consumed in higher percentages—making up to 10-25 percent of total daily calories.
For example, someone with a daily diet of 2000 Calories is recommended to have about 65 grams of fat. Considering that each gram of fat provides 9.1 Calories, the percentage of calories supplied by this amount of fat would be 65 g x 9.1 Calories/g, which equals to 591.5 Calories from fat, constituting approximately 30 percent of the total calorie intake.
