How do dietary habits affect blood lipids? A scientific diet is key to managing blood lipids.
Developing healthy eating habits is essential: The effects of food composition on blood lipids are particularly significant. Extensive animal experiments have shown that feeding animals high-cholesterol and high-fat diets can induce elevated blood lipids in various animals (including monkeys, chickens, rabbits, rats, and mice), gradually leading to experimental atherosclerosis. Replacing the high-cholesterol and high-fat diet with regular feed causes a rapid decline in atherosclerotic symptoms.
Meanwhile, numerous epidemiological surveys in humans also show that habitually consuming animal fats (mainly saturated fatty acids) easily leads to elevated levels of cholesterol and low-density lipoprotein (LDL) in the blood. Elevated levels of these two substances accelerate atherosclerosis. Simultaneously, they lower high-density lipoprotein (HDL). HDL plays a vital role in protecting blood vessels and delaying atherosclerosis. Ingesting plant-based fats (mainly monounsaturated and polyunsaturated fatty acids), fiber, and plant proteins can lower blood lipids.
A clinical study involving 846 men as the experimental group involved consuming foods low in saturated fatty acids and cholesterol, while increasing the amount of plant-based fats in their diet. The results showed a decrease in plasma total cholesterol and triglyceride levels, but no decrease in high-density lipoprotein (HDL). After an 8-year follow-up, a significant decrease was observed in the total number of fatal atherosclerotic diseases (including sudden death from coronary heart disease and stroke), with a 31.4% reduction in mortality compared to the control group. The overall incidence of non-fatal and fatal atherosclerotic diseases also showed a significant decrease, with a 31.3% reduction compared to the control group.
This demonstrates that daily dietary habits directly affect blood lipid and lipoprotein levels and are closely related to the occurrence and development of atherosclerosis. Understanding this and consciously cultivating good dietary habits is crucial for preventing atherosclerosis.
