The primary source of cholesterol in the diet is animal products, including meat, dairy, and eggs. The body also produces cholesterol naturally, which is essential for synthesizing hormones, vitamin D, and bile acids for digestion. While dietary cholesterol has been linked to an increase in blood cholesterol levels, recent research suggests that the impact varies among individuals. Balancing cholesterol intake with a diet rich in fruits, vegetables, and whole grains can support cardiovascular health while managing cholesterol levels effectively.
