It can be found in many foods, including soybeans and egg yolks. Lecithin is taken as a medicine and is also used in the manufacturing of medicines. Lecithin is used for treating memory disorders such as dementia and Alzheimer's disease. Lecithin works as an emulsifier, meaning it suspends fats and oils and keeps them from mixing with other substances. Lecithin supplements can be purchased to help treat high cholesterol, as a breastfeeding aid, and to treat ulcerative colitis, among other things. -lecithin -dispersed -soy Your response is correct! Function of Fats How does the body utilize fats? Select all that apply. For temperature regulation Protein sparing effect Glucose regulation To protect organs Hormone synthesis The body uses fat (triglycerides) to protect organs, for temperature regulation, and hormone synthesis. The protein sparing effect is when carbohydrates prevent the body from breaking down proteins to use as an energy source. Fats do not play a role in glucose regulation. Your response is correct!Total calories from fat should compose 30% or less of all calories consumed each day. Your total fat calories should be no more than 30% of all the calories you eat each day. If you have heart disease or a high level of LDL ("bad") cholesterol, you may need to restrict your saturated fat to 5% to 6%, the AHA says. Limiting fat shouldn't be the sole focus of a healthy diet, however. Total calories are also important. To not gain weight, you must balance the number of calories you consume with the number of calories you expend in exercise and other daily activity. Your response is correct! Types of Fats The main difference between lipids and fats is that lipids are a broad group of biomolecules whereas fats are a type of lipid. Fat is stored in the adipose tissue and under the skin of animals. It is mainly used as an energy-storage moleculein the body. Most steroids in the body serve as hormones. It is interesting to note that one pound of adipose tissue yields about 3500 calories. In addition, fat provides 9 K-calories of energy per gram.

Select all that apply. Sterols are not an essential nutrient since the liver can produce the cholesterol it needs to maintain good health. Sterols are used by the body for vitamin D synthesis and bile production. The body uses phospholipids for cell membrane structure. The human body cannot synthesize vitamin C. Liver function and gallbladder health are not dependent on the presence of sterols in the diet. -bile production -vitamin D synthesis Your response is correct! Calories From Fat With 9 calories per gram, fat is the most calorie dense source of energy in the diet when compared to the 4 calories per gram in proteins and carbohydrates. To calculate the number of calories from fat in a food, multiply the grams of fat in the food by 9 calories. For example, a one-half cup serving of vanilla ice-cream has 7.3 grams of fat. Multiply 7.3 by 9 to determine that 65.9 calories are from fat, which is almost half of the total calories! Not a very low-fat snack. [Show More]
