Study Notes
Body Fat and Fat Storage
- Most body fat is stored in the form of triglycerides.
- Triglycerides are esters composed of glycerol and three fatty acids.
Phospholipids
- Lecithin is classified as a phospholipid, a key component of cell membranes.
- Phospholipids play a vital role in cellular structure and function.
Cholesterol Transport
- Low-Density Lipoprotein (LDL) is responsible for transporting cholesterol from the liver to tissues in the body.
- Elevated LDL levels are associated with increased risk of heart disease.
Fat Intake Recommendations
- Total fat intake should not exceed 20% of total daily calories.
- Saturated fat intake should be limited to 5% of total daily calories.
Dietary Fats Post-Meal
- After a meal, newly digested fats appear in the form of chylomicrons, which transport dietary lipids through lymphatic and blood circulation.
Solid Fats
- Liquid fats at room temperature can be made more solid through hydrogenation, a chemical process that adds hydrogen atoms to unsaturated fatty acids.
Daily Fat Consumption
- For a daily intake of 2000 calories, to meet the recommended fat intake of less than 30%, Mike should consume approximately 67 grams of fat.
Saturated Fatty Acids Effects
- Excessive consumption of saturated fatty acids tends to increase cholesterol deposits in arteries, potentially leading to cardiovascular disease.
Trans Fatty Acids
- Trans fatty acids have harmful effects on health by raising LDL cholesterol levels and lowering High-Density Lipoprotein (HDL) cholesterol levels.
Heart-Healthy Foods
- Nuts are considered heart-healthy as they are rich in monounsaturated fatty acids, which can help reduce bad cholesterol levels and promote heart health.
