The USDA's guidelines recommend that Americans consume less than 10 percent of their calories from saturated fats and replace the remaining fats with healthy monounsaturated and polyunsaturated fatty acids. This means that if you consume a 2,000-calorie diet, no more than 200 calories should come from saturated fats. Furthermore, there are 9 calories in every gram of fat, meaning intake should be limited to 22 grams.
