The Truth About Genetics, Diet, and Habits That Are TOP for Your Health
When we talk about cholesterol, we usually divide it into "bad" (LDL) and "good" (HDL). However, what many don't know is how it is created in our body. Our body (primarily the liver) produces about 80 percent of the total cholesterol needed for normal cell function, while the remaining 20 percent is ingested through food. These facts raise a key question: how much do the genes we inherited from our parents influence, and how much does our lifestyle?
TL;DR
- The body, primarily the liver, produces about 80% of its cholesterol, while 20% comes from food.
- Genetics plays a significant role in fat metabolism, with conditions like familial hypercholesterolemia causing extremely high cholesterol levels from a young age.
- Lifestyle factors such as fast food, processed meats, full-fat dairy, margarine, pastries, sedentary behavior, abdominal fat, and smoking negatively impact cholesterol levels.
- A Mediterranean diet rich in fiber, replacing unhealthy fats with olive oil, consuming fatty fish, and engaging in at least 30 minutes of brisk walking daily can improve cholesterol.
- Regular physical activity like swimming, cycling, or jogging five days a week can boost HDL cholesterol.
- Healthy habits can significantly alter cholesterol levels and protect heart health, even with a genetic predisposition.
