'Healthy' Foods That Might Actually Worsen Your Cholesterol

31. Cod Liver Oil: A Healthy Fat with a Catch

Cod liver oil is a traditional health tonic, valued for its high content of omega-3s and vitamins A and D. However, it's a very specific type of fat that can impact cholesterol. While the omega-3s are beneficial, cod liver oil is also high in dietary cholesterol. While dietary cholesterol has less impact on blood cholesterol for most people than saturated fat, for individuals who are genetically predisposed to high cholesterol, this can be a concern. Additionally, the high vitamin A content can be toxic in large doses. Always consult a doctor before supplementing, especially for those with existing health conditions.

32. Frozen Diet Meals: The Convenient Meal with Hidden Traps

Frozen diet meals promise a quick, portion-controlled solution for weight loss and "healthy" eating, but they can be a major cholesterol risk. To make them shelf-stable and palatable, manufacturers often load them with processed vegetable oils (which can become inflammatory when heated at high temperatures), excessive sodium, and hidden sugars. This trifecta can lead to high blood pressure, inflammation, and elevated LDL cholesterol. Plus, they’re often low in fiber and antioxidants, which are essential for heart health. Instead of relying on a box, batch-cook your own heart-healthy meals using lean protein, whole grains, and plenty of vegetables to ensure you're in control of every ingredient.
