Cholesterol is a fatty substance in our blood. While our bodies need some cholesterol to function correctly, too much of it can lead to health issues.

High cholesterol, especially LDL (“bad” cholesterol), increases the risk of heart disease and stroke. Diet plays a crucial role in managing cholesterol levels.

So, if you’re looking to keep your cholesterol in check, it’s essential to know which foods can raise it and which can help lower it.

Foods That Can Raise Cholesterol Levels

Certain foods are known to increase cholesterol levels, based on numerous scientific studies. Here’s a list of the main culprits:

Processed Meats: Sausages, bacon, and hot dogs might taste delicious, but they’re not the best for heart health.

A study in the Journal of the American Heart Association found that consuming processed meats can increase the risk of heart disease partly due to their cholesterol-raising effect.

Fried Foods: Fried foods, like french fries and fried chicken, are usually cooked in trans fats or partially hydrogenated oils. These fats can increase LDL cholesterol levels. According to the American Journal of Clinical Nutrition, trans fats are linked to a higher risk of heart disease.

Baked Goods: Pastries, cakes, and cookies often contain high amounts of saturated fats and trans fats. Both of these can raise cholesterol levels.

Research published in the British Medical Journal noted that reducing trans fats from diets led to significant drops in cholesterol and heart disease rates.

Whole-Fat Dairy Products: Full-fat cheese, milk, and butter have been associated with increasing cholesterol levels.

A review in the European Journal of Clinical Nutrition advised moderation in consuming these products, especially for those already with high cholesterol.

Organ Meats: Foods like liver, kidney, and other organ meats are naturally high in cholesterol. While they can be nutritious, they’re best consumed in moderation.

Foods That Can Help Lower Cholesterol Levels

It’s not all about avoiding certain foods; some foods can actively help lower cholesterol levels:

Oats and Whole Grains: These contain beta-glucans, a type of soluble fiber that can help lower cholesterol.

A study in the American Journal of Clinical Nutrition found that consuming oats regularly reduced LDL cholesterol without affecting the good HDL cholesterol.

Nuts: Walnuts, almonds, and other nuts can help reduce blood cholesterol. A meta-analysis in the Archives of Internal Medicine suggested that eating a daily serving of nuts led to a significant reduction in total cholesterol levels.

Fruits and Vegetables: Packed with essential nutrients and fibers, fruits and veggies can help lower cholesterol. Berries, apples, and citrus fruits are particularly effective, as reported in a review from the Nutrition Reviews journal.

Fatty Fish: Salmon, mackerel, and sardines are rich in omega-3 fatty acids, which can reduce cholesterol levels. The Journal of Nutrition suggests that consuming fatty fish twice a week can have significant heart health benefits.

Taking Control of Your Diet

Knowing which foods to avoid and which to include can make a significant difference in managing cholesterol levels:

Stay Informed: Read food labels when shopping. Look out for trans fats or saturated fats in the ingredients list.

Cook Smart: Opt for healthier cooking methods like baking, grilling, or steaming instead of frying.

Consult a Professional: If you’re unsure about what to eat, consult a nutritionist or dietitian. They can provide personalized advice based on your health needs.


While genetics and other factors can influence cholesterol levels, diet plays a central role. By making informed choices, we can actively manage our cholesterol and improve our overall heart health.

Remember, it’s not just about eliminating harmful foods, but also about including cholesterol-lowering ones in our meals.

If you care about heart health, please read studies that vitamin K helps cut heart disease risk by a third, and a year of exercise reversed worrisome heart failure.
