10+ worst foods for your cholesterol, according to experts

Coconut oil sat on the “superfood” shelf for over a decade. Nutritionists endorsed it, wellness influencers drizzled it over everything, and health food stores moved it by the case. Meanwhile, cardiologists were pointing at something else entirely: the foods people eat regularly, day after day, have a far more measurable impact on cholesterol than any single trendy swap.

The reason coconut oil makes a useful starting point is what’s actually in it. Limiting the amount of cholesterol you eat isn’t the best way to lower harmful cholesterol in your blood. What heart doctors now say does more is limiting saturated fat, and coconut oil is a concentrated source of exactly that. The broader question of which foods are genuinely driving the worst cholesterol outcomes is one most people haven’t fully answered for themselves, even if they think they have.

The distinction between “bad” saturated fats and “good” unsaturated fats is the crux of the issue: saturated fats raise LDL cholesterol, while unsaturated fats can help lower it. LDL, or low-density lipoprotein, is the form of cholesterol that builds up inside artery walls, increasing the risk of heart attack and stroke. The National Heart, Lung, and Blood Institute recommends that less than 7% of all daily calories come from saturated or trans fats. Most Americans are well above that. High cholesterol continues to be a significant health issue, with serious implications for cardiovascular health, and dietary adjustments are one of the most effective interventions available.

Here are 12 of the worst foods for cholesterol, based on current evidence.

1. Trans Fats: Partially Hydrogenated Oils and Stick Margarine

Trans fat sits at the very top of any list of cholesterol threats. According to the Mayo Clinic, “trans fat is the worst type of fat to eat” because it raises LDL (bad) cholesterol while simultaneously lowering HDL (good) cholesterol – a double hit that dramatically raises cardiovascular risk.

The FDA took action in 2015, determining that partially hydrogenated oils – the primary industrial source of trans fat – were no longer “Generally Recognized as Safe,” effectively banning them to prevent heart attacks. That doesn’t mean trans fats have disappeared entirely. A food label can show 0 grams of trans fat if a single serving contains less than 0.5 grams, and products manufactured before the ban may still be on shelves. The safest move is to check ingredient lists for the phrase “partially hydrogenated oil” – that’s the giveaway.

Some margarines still contain trans fats that raise LDL and lower HDL cholesterol. Stick margarines in particular tend to be higher in trans fats than soft tub versions. When choosing a spread, look for one made with liquid plant oils and zero grams of trans fats per serving, then confirm no partially hydrogenated oil appears anywhere in the ingredients list.

2. Processed Meats (Bacon, Sausage, Deli Meat, Hot Dogs)

Hot dogs, sausage, and bacon use the fattiest cuts of red meat, and therefore tend to be high in cholesterol and saturated fat. Saturated fat pushes LDL up, while excess sodium strains blood vessels and raises blood pressure – and processed meats deliver both in the same bite.

The cardiovascular case against processed meat is backed by large-scale data. Researchers at the University of Oxford found that a 50g daily increase in processed meat intake – roughly two strips of bacon – was associated with an 18% higher risk of coronary heart disease (a 2021 study, the most recent large-scale analysis on this specific intake threshold).

Most of the available cardiovascular data on this topic comes from observational studies, and consistently across that body of research, processed meats are associated with increased cardiovascular disease risk. Compared to unprocessed red meat, they carry additional risk from the additives, sodium, and preservation methods used. Swapping deli meat for canned fish, grilled chicken, or hummus a few days a week is one of the most direct upgrades available for a cholesterol-conscious diet.

3. Fatty Red Meat (Beef, Pork, and Lamb)

Red meat, like beef, pork, and lamb, as well as processed meats like sausage, are among the worst foods for high cholesterol given their high saturated fat content. The issue is most acute with specific cuts – ribeye, ribs, T-bone, and pork chops deliver far more saturated fat per serving than leaner options like sirloin or tenderloin.

The effect on LDL is cumulative, not just from single meals. Research also shows a benefit to changing protein sources: replacing red meat with plant protein sources has been associated with favorable changes in both total cholesterol and LDL cholesterol levels. That doesn’t mean eliminating red meat entirely. Leaner cuts eaten in moderation, alongside a diet built around vegetables, legumes, and fish, sit within a range most cardiologists consider manageable.

The American Heart Association recommends limiting saturated fats to less than 6% of total daily calories. A single serving of fatty beef can use up most or all of that allowance in one sitting. When red meat is on the menu, choosing leaner cuts and keeping portions to around three ounces – about the size of a deck of cards – is the practical target.

4. Fried Foods (Fried Chicken, French Fries, Donuts)

Foods that have taken a dip in the deep fryer – like chicken wings, mozzarella sticks, and onion rings – are among the worst foods for cholesterol. The mechanics are straightforward: frying forces food to absorb large amounts of cooking oil, dramatically increasing both its calorie count and its saturated and trans fat load.

Trans fats raise LDL and lower HDL simultaneously, and high LDL combined with low HDL causes cholesterol to build up in arteries. Deep-fried foods like fried chicken, mozzarella sticks, and donuts tend to be high in unhealthy fats to begin with, making them a double threat – and even eating fried fish has been linked to poor heart health in a 2024 review of research.

If you like the crunch of fried food, an air fryer with a small amount of olive oil gets you close to the texture with a fraction of the fat. Baking at a high temperature – around 425°F – also works well for potatoes, chicken, and vegetables.

5. Full-Fat Dairy (Butter, Cream, Whole-Milk Cheese)

Butter and cream are a different story from fermented full-fat dairy. Dietary saturated fatty acids found in milk, butter, and cheese increase LDL cholesterol by decreasing the liver’s ability to clear LDL from the blood and simultaneously increasing LDL production.

Butter and similar fats like lard and ghee are roughly 50% saturated fat, with one teaspoon containing around 5 grams. That’s a meaningful chunk of the daily 6% saturated fat ceiling the American Heart Association recommends. Cook regularly with butter and you can hit that ceiling before breakfast is over. The 2025 Dietary Guidelines Advisory Committee’s review found that replacing butter with plant-based oils and spreads high in unsaturated fatty acids decreases LDL levels.

In a January 2026 statement, the American Heart Association expressed concern about full-fat dairy, encouraging the consumption of low-fat and fat-free dairy products instead. The AHA’s concern centers on LDL cholesterol – the type most closely associated with arterial plaque buildup – because saturated fat raises LDL, and the evidence for that mechanism remains solid. Switching from butter to olive oil or a plant-based spread for everyday cooking is one of the simplest, evidence-backed reductions you can make.

6. Coconut Oil

Coconut oil is one of the hidden sources of saturated fat that most people never check for on ingredient labels. Its reputation as a plant-based oil has caused widespread confusion about its actual fat profile. According to the American Heart Association, coconut oil is 82% saturated fat – more than butter – and studies show it raises LDL cholesterol just as much as beef fat (a 2019 AHA advisory, still the most comprehensive institutional statement on this topic).

That saturated fat content means coconut oil does to your LDL what any saturated fat does: it reduces the liver’s capacity to clear LDL from the blood and increases LDL production at the same time. The fact that it comes from a plant doesn’t change the biochemistry. Cardiologists in 2026 have noted that animal fats that are solid at room temperature – like beef tallow – can raise LDL in ways that unsaturated fats do not, and the same logic applies directly to coconut oil.

For everyday cooking, olive oil, avocado oil, or sunflower oil are strongly preferred alternatives. Using coconut oil occasionally in cooking is unlikely to cause harm for most people, but treating it as a daily cooking fat equivalent to olive oil carries meaningful caveats.

7. Baked Goods and Pastries (Cookies, Croissants, Cakes)

Baked goods, like cupcakes, are among the worst foods for high cholesterol. They combine multiple cholesterol-raising ingredients in a single product: butter or shortening for saturated fat, refined white flour that spikes blood sugar, and added sugar that elevates triglycerides – a type of fat in the blood that compounds cardiovascular risk alongside high LDL.

Commercially produced baked goods are often loaded with hydrogenated oils and added sugars, which increase inflammation and heart disease risk. Store-bought pastries, croissants, and packaged muffins tend to be the highest-risk items because they’re made at scale with the cheapest available fats, which are frequently partially hydrogenated or palm oil-based. Both raise LDL.

Check the ingredient list before buying any packaged baked good. If “partially hydrogenated oil,” “palm oil,” or “shortening” appears near the top, that product is contributing meaningfully to your LDL burden. Home-baked versions made with olive oil and whole-grain flour are a workable substitute that eliminates most of the worst offenders.

8. Sugar-Sweetened Beverages (Soda, Sweetened Juice, Energy Drinks)

Sugary drinks connect to LDL and triglycerides through a direct biological pathway. They spike blood glucose levels, which leads to inflammation and insulin resistance. Unlike sugar eaten in solid food, liquid sugar arrives in the bloodstream almost immediately because there’s no fiber to slow absorption.

Research from Harvard Health links higher intakes of sugary drinks to increased unhealthy blood fats, including raised LDL cholesterol. The mechanism runs through the liver: excess sugar, particularly fructose, gets converted to fat in the liver, which then enters the bloodstream as triglycerides and compounds the LDL problem. Drinking more than one sugar-sweetened beverage per day is associated with lower HDL and higher triglyceride levels.

A large 2024 study published in Frontiers in Public Health, involving nearly 70,000 participants in Sweden, found that consuming sweet drinks was worse for cardiovascular health than any other form of sugar, with higher intake significantly increasing the risk of ischemic stroke, heart failure, and atrial fibrillation. Switching to water, sparkling water, or unsweetened tea is the most immediate dietary change most people can make to their cardiovascular risk profile.

9. Refined Carbohydrates (White Bread, White Rice, Packaged Cereals)

Research has found that diets high in refined grains like white bread are associated with a significantly higher risk of cardiovascular disease and stroke. The American Heart Association’s updated 2026 dietary guidance describes refined grain foods as delivering fast-absorbing carbohydrates with few nutrients or fiber – metabolically closer to pure sugar than most people realize.

The cholesterol impact works through triglycerides. Research published in the Journal of Clinical Medicine links sugar and dyslipidemia – abnormal levels of blood fats – in a pattern that includes both elevated triglycerides and depressed HDL. A 2010 Current Atherosclerosis Reports study on refined carbohydrate intake found that refined carbohydrates increase triglycerides and reduce HDL cholesterol, worsening the overall cholesterol profile even without a corresponding rise in saturated fat intake.

The 2025-2026 updated US dietary guidelines kicked refined grains off the healthy eating pyramid entirely, advising people to “significantly reduce” highly processed refined carbohydrates – including white bread, packaged breakfast foods, and similar products. Swapping white bread for a 100% whole-grain alternative and choosing steel-cut oats over boxed cereal are two replacements that improve both fiber intake and the triglyceride-HDL balance.

10. Fast Food

Fast food concentrates the worst offenders on this list into a single meal: refined carbs in the bun, trans fats from frying, processed meat in the patty, and full-fat dairy in the cheese and sauce. Diet plays a critical role in heart health, and certain foods can negatively impact the cardiovascular system, contributing to high blood pressure, elevated cholesterol, and increased risk of heart disease.

United Digestive’s 2025 analysis notes that fast food high in unhealthy fats can lead to high cholesterol and poor heart health. The issue isn’t one burger – it’s frequency. Eating fast food several times a week means the combined effect of trans fats, saturated fats, refined carbs, and sodium accumulates across hundreds of meals per year. As Dr. Romit Bhattacharya, associate director of the Cardiac Lifestyle Program at Massachusetts General Hospital, puts it: “If you’re doing 80% of the right things 80% of the time, that’s a great start.”

When fast food is unavoidable, grilled over fried, skipping the bun, choosing water or unsweetened tea instead of soda, and skipping the cheese and sauce removes several of the most damaging ingredients in a single order.

11. Whole-Milk Coffee Drinks and Non-Dairy Creamers

This one catches people off guard. A single large flavored latte made with whole milk and flavored syrup can contain 10 or more grams of saturated fat before you’ve eaten anything. Non-dairy creamers are popular additions to coffee but often contain hydrogenated oils, artificial sweeteners, and emulsifiers. These ingredients can raise cholesterol levels and contribute to inflammation.

French press and Turkish coffee also present a less obvious cholesterol risk: these brewing methods let through cafestol, a compound that raises LDL cholesterol. Espresso contains cafestol too, but serving sizes are small enough that the effect is minimal. Drip coffee filters trap cafestol, making filtered coffee the default recommendation for anyone monitoring their LDL.

For creamers, switching to unsweetened oat milk or a small pour of low-fat milk eliminates both the hydrogenated oil risk and the flavored syrup sugar load.

12. Alcohol (Heavy or Regular Intake)

The cholesterol picture with alcohol is more complicated than with any other item on this list, and the nuance matters. While light to moderate drinking may increase HDL cholesterol, heavy alcohol use is associated with elevated levels of LDL cholesterol, total cholesterol, and triglycerides, as well as a greater risk of heart disease and death.

Some research suggests that low alcohol intake may help increase HDL cholesterol. The evidence also clearly shows that heavier alcohol intake increases triglycerides – and possibly LDL cholesterol. To lower the risk of heart disease, current guidance recommends no more than two drinks a day for men and one drink per day for women.

For anyone already dealing with high LDL or elevated triglycerides, keeping alcohol in the “occasional” category rather than the “daily” category is the practical takeaway. The cholesterol benefit of light drinking is modest, and the risks associated with heavier intake are not. Anyone on a statin or other cholesterol-lowering medication should also check with their doctor, since alcohol can interact with some of these drugs.

What to Do Now

The foods on this list share a common thread: they either raise LDL directly through saturated or trans fat, or they raise triglycerides and lower HDL through excess sugar and refined carbs. Often, both mechanisms run at once. Diet is one of the most powerful tools for changing your cholesterol picture, which means knowing what to reduce actually moves the needle on your next blood panel.

You don’t need to eliminate every item here. Prioritize the ones you eat most frequently. If bacon, butter, and sugary drinks appear in your daily routine, those are the three places where consistent reduction will show up most clearly in lab results. Swap partially hydrogenated oils for olive oil, move toward whole grains, and replace sugary drinks with water. Cardiologists in 2026 note that unsaturated fats from plant oils do not raise LDL the way saturated fats do – making the switch from coconut oil or butter to olive oil one of the most evidence-backed single changes in nutrition right now. For a cholesterol-raising diet, the pattern matters more than any single meal. Getting the frequency right on the highest-impact items is where the work is.
