The foods that raise “bad” (LDL) cholesterol the most are those high in saturated fat, trans fat, and added sugars. Red meat, full-fat dairy, fried foods, commercially baked goods, and certain cooking oils are the biggest drivers. What matters most isn’t the cholesterol already in a food, but how that food changes the way your liver handles cholesterol once you eat it.
How Food Raises LDL Cholesterol
Your liver is responsible for pulling LDL cholesterol out of your bloodstream using specialized receptors on its surface. When you eat foods high in saturated fat, those fats suppress the activity of these receptors, so less LDL gets cleared and more stays circulating in your blood. Research in the Journal of Lipid Research confirmed this works in reverse too: when people reduced their saturated fat intake, the number of LDL receptors on their cells increased, helping their bodies remove LDL more efficiently.
This is why the American Heart Association recommends keeping saturated fat below 6% of your total daily calories. On a 2,000-calorie diet, that’s about 13 grams of saturated fat per day, which is easier to exceed than most people realize.
Red Meat and Full-Fat Dairy
These are the most common sources of saturated fat in Western diets. A 3-ounce serving of roasted beef rib (a modest portion, smaller than most restaurant steaks) contains about 10 grams of saturated fat, nearly your entire daily budget in one sitting. A single cup of whole milk has roughly 5.5 grams. Even a small pat of butter adds about 2.5 grams.
Cheese, cream, and ice cream follow the same pattern. The saturated fat in these foods doesn’t just nudge LDL upward slightly. Over time, consistent intake well above that 6% threshold keeps your liver’s LDL receptors suppressed, allowing cholesterol to accumulate in your arteries.
Trans Fats: The Worst Offenders
Trans fats are uniquely harmful because they hit cholesterol from both directions: they raise LDL and lower HDL (“good”) cholesterol at the same time. While the FDA has largely banned partially hydrogenated oils in the U.S., small amounts can still appear in older product formulations and imported foods. Common sources include commercially baked cakes, cookies, and pies, frozen pizza, microwave popcorn, refrigerated dough products like biscuits and rolls, fried foods (french fries, doughnuts, fried chicken), nondairy coffee creamers, and stick margarine.
Check ingredient lists for “partially hydrogenated oil.” A product can legally list 0 grams of trans fat on the nutrition label if it contains less than 0.5 grams per serving, so the ingredient list is the more reliable indicator.
Coconut Oil and Tropical Oils
Coconut oil has been marketed as a health food, but a meta-analysis published in Circulation found that coconut oil raised LDL cholesterol by about 10.5 mg/dL compared to nontropical vegetable oils like olive, canola, or soybean oil. That translates to roughly an 8.6% increase in LDL. Palm oil and palm kernel oil have a similar saturated fat profile. If you’re cooking with coconut oil regularly and your LDL is elevated, switching to olive oil or avocado oil is one of the simpler changes you can make.
Refined Carbs and Added Sugars
Fat isn’t the only macronutrient that affects cholesterol. Diets high in refined carbohydrates and added sugar trigger your liver to produce more VLDL particles, which are precursors to LDL. Research published in The Journal of Clinical Investigation showed that high-carbohydrate diets led to overproduction of these particles, which then circulate longer in the bloodstream and get remodeled into smaller, denser LDL, a particularly harmful subtype that penetrates artery walls more easily.
Sugary drinks, white bread, pastries, candy, and breakfast cereals with added sugar all contribute to this process. The problem compounds when these foods replace healthier options like whole grains, fruits, and vegetables that contain fiber, which actively helps lower LDL.
Ultra-Processed Foods
Many of the foods already mentioned fall under the umbrella of ultra-processed foods, but the category is worth calling out separately. A study published in JACC: Advances, drawing on data from the Multi-Ethnic Study of Atherosclerosis, found that each additional daily serving of ultra-processed food was associated with a 5.1% increased risk of cardiovascular events. People in the highest consumption group had a 66.8% higher cardiovascular risk compared to those who ate the least.
Ultra-processed foods tend to combine multiple cholesterol-raising ingredients at once: saturated fat, refined flour, added sugar, and sometimes residual trans fats. Think frozen meals, packaged snacks, fast food, and processed meats like hot dogs and sausages. The combination makes their collective impact on blood lipids worse than any single ingredient alone.
What About Cholesterol in Food?
Eggs, shrimp, and organ meats are high in dietary cholesterol, but the relationship between the cholesterol you eat and the cholesterol in your blood is less direct than once thought. Foods high in dietary cholesterol often also contain significant saturated fat, and the saturated fat is the bigger problem. The CDC notes that because high-cholesterol foods frequently come packaged with saturated fat (think eggs fried in butter, or shrimp in a cream sauce), it’s best to focus on reducing saturated fat overall rather than obsessing over dietary cholesterol numbers alone.
That said, dietary cholesterol isn’t completely neutral. If your LDL is already high, eating large amounts of cholesterol-rich foods on top of a diet high in saturated fat will make the problem worse. The practical move is to pay attention to how cholesterol-rich foods are prepared and what they’re served with.
Practical Swaps That Lower LDL
- Cooking oils: Replace coconut oil, palm oil, and butter with olive oil or canola oil.
- Protein: Swap fatty cuts of beef and processed meats for chicken breast, fish, beans, or lentils.
- Dairy: Choose low-fat or fat-free versions of milk, yogurt, and cheese.
- Snacks: Trade packaged baked goods for nuts (almonds and walnuts are especially beneficial), fresh fruit, or whole-grain options.
- Carbs: Replace white bread, sugary cereals, and pastries with oats, brown rice, and other whole grains that contain soluble fiber.
These changes work because they directly address the mechanism: less saturated fat means more active LDL receptors on your liver cells, which means more LDL pulled out of your bloodstream. Soluble fiber from oats, beans, and fruits binds to cholesterol in the digestive tract and carries it out before it can be absorbed, providing an additional benefit on top of simply cutting the bad stuff.
