Serum triglycerides are one type of fat present in blood (other type is cholesterol). Its normal range is less than 200 mg% and if it is more than 500mg% it require treatment with drugs. Between 200-500 mg%, restriction of all types of fatty and oily foods is required. Along with physical exercise... brisk walking at least 45 min a day is considered to be the best to reduce blood lipids (both cholesterol and triglycerides).
