'Healthy' Foods That Might Actually Worsen Your Cholesterol

29. Tuna (Canned): A Protein Staple, Not Always Heart-Smart

Canned tuna is a convenient protein staple, but it can quietly contribute to high cholesterol, especially if you're not choosing wisely. Tuna canned in oil (like soybean or vegetable oil) can add unwanted processed fats to your diet, which can promote inflammation and disrupt your cholesterol profile. The best option is to choose tuna canned in water, which is low in fat and a great source of lean protein and heart-healthy omega-3s. Be mindful of added ingredients and opt for the simplest choice to keep your meals clean and heart-friendly.

30. Canned Tomatoes: The Hidden Sugar to Balance Acidity

Canned tomatoes, tomato paste, and many store-bought pasta sauces are a staple in kitchens worldwide, but they can be a source of hidden sugars that raise cholesterol. To balance the natural acidity of the tomatoes and enhance flavor, manufacturers often add sugar, high-fructose corn syrup, or other sweeteners. These additives can spike blood sugar and promote triglyceride production, both of which are linked to elevated LDL cholesterol. Always read the ingredient list and nutrition label carefully, and choose brands with no added sugar. For a truly heart-healthy meal, make your own sauce from fresh tomatoes.
