The fatty acids are arranged opposite from each other so that the triglyceride looks vaguely like a tuning fork. The fatty acids may be any combination of saturated or unsaturated. Regardless of the type of fatty acids, all triglycerides contribute 9 Calories for every gram consumed. Often, cholesterol is mistakenly thought to be a part of dietary fat. However, dietary cholesterol comes from animal foods only, whereas triglycerides come from both animal and plant foods.
Cholesterol also looks very different than triglyceride.
Unlike triglycerides, cholesterol does not contain fatty acids. In the body, cholesterol is not used for energy, so it does not provide any calories when eaten in the diet. Intake of dietary fat should not exceed 30 percent of the calories we consume in one day. All you have to do now is use the Nutrition Facts information on package labels to find out how many total grams of fat are in all of your food. Substitute softer, more liquid fats for part of the solid or saturated fat you were eating.
