How do walnut kernels help lower cholesterol levels?
Summary: Walnut kernels help lower cholesterol levels due to their high content of omega-3 fatty acids, antioxidants, and fibre. They reduce LDL (bad) cholesterol and increase HDL (good) cholesterol.
Detailed Answer:
- Omega-3 Fatty Acids: Walnuts are rich in alpha-linolenic acid (ALA), a type of omega-3 fatty acid that helps reduce LDL cholesterol levels and improve heart health.
- Antioxidants: Walnuts contain antioxidants like polyphenols that prevent oxidation of LDL cholesterol, reducing the risk of plaque formation in arteries.
- Fibre: The fibre content in walnuts helps in binding cholesterol in the digestive system, preventing its absorption into the bloodstream.
- Phytosterols: Walnuts contain phytosterols, plant compounds that interfere with cholesterol absorption, leading to lower LDL cholesterol levels.
-
Healthy Fats: The monounsaturated and polyunsaturated fats in walnuts contribute to overall cholesterol balance by increasing HDL (good) cholesterol.
