Cholesterol Risks Not Limited to Overweight Individuals, Genetic Factors Play Key Role
Cholesterol, a fatty substance produced by the liver, is essential for building cells and producing hormones. However, high levels of LDL (low-density lipoprotein) cholesterol, often referred to as 'bad' cholesterol, can increase the risk of heart attacks and strokes by accumulating on artery walls and restricting blood flow. Contrary to common belief, high LDL cholesterol is not solely a concern for overweight individuals. According to Naveed Sattar, a professor of cardiometabolic medicine at the University of Glasgow, genetics are the primary factor influencing LDL cholesterol levels, with diet playing a smaller role. Saturated fats, found in foods like cakes and biscuits, can raise LDL levels, meaning even lean individuals can have high cholesterol due to genetic predispositions or dietary habits. Obesity, while having minimal direct impact on LDL levels, is linked to higher triglycerides and remnant cholesterol, increasing cardiovascular disease risk.
