Hi Joan,
These are the guidelines from the American Heart Association for cholesterol management.
Total dietary fat intake - 30% or less of total calories daily
Saturated fat intake - limited to less than 7% of your total daily calories
Trans fat intake - less than 1% of your total daily calorie intake
Cholesterol should be limited to less than 300 mg/day.
In order to calculate the fat grams, you need to know your average calorie intake each day (or what it should be to maintain a healthy weight). If you know that number, simply mutliply by the percent and divide by 9 to get your fat grams.
Example for 2000 calorie diet:
2000 calories x 30% total fat = 600 fat calories divided by 9 =
67 grams of fat/day (or less)
