A common misconception regarding high-cholesterol foods is that consuming them directly raises blood cholesterol levels. Foods like eggs and shrimp are often labeled bad for heart health, but research shows their impact is minimal for most people. The body's cholesterol production is largely regulated by genetics and overall fat intake rather than solely from dietary cholesterol. Instead, saturated and trans fats in the diet hold more influence on blood cholesterol levels, emphasizing the importance of a balanced diet.
