Study Notes
Lipid Digestion and Absorption: Key Points
- Lipids like meat, chicken, pork, cheese, and others are broken down in the body through a complex process involving bile, pancreatic lipase, and enterocytes.
- Different fatty acids, classified by chain length, are involved in lipid digestion and absorption.
- Lipoproteins (LPs) transport water-insoluble lipids like triacylglycerol, cholesterol, and fat-soluble vitamins.
- Chylomicrons transport lipids from the small intestine into the bloodstream for delivery to peripheral tissues.
- The liver is a major lipid-producing organ, and excess protein, carbohydrates, or alcohol can be used to make triglycerides or cholesterol.
- Very-low-density lipoproteins (VLDL) transport lipids out of the liver, while low density lipoproteins (LDL) and high-density lipoproteins (HDL) are involved in reverse cholesterol transport.
- High-fat diets have been linked to a higher incidence of heart disease, but the relationship is complex and not always direct.
- Atherosclerosis, the hardening of arteries due to cholesterol buildup, is a major risk factor for cardiovascular disease.
- Risk factors for atherosclerosis include high blood pressure, family history, smoking, diabetes, obesity, and low HDL.
- New data suggests complexities in the role of LDL, HDL, and triglycerides in cardiovascular disease risk.
- Studies have not shown a clear benefit of increasing HDL cholesterol for cardiovascular disease, and the measurement of HDL cholesterol may not be a reliable marker for associated risk.
- Fasting triglyceride levels can predict cardiovascular disease risk, and polyunsaturated fatty acids have both pro and anti-inflammatory properties.
