Organ meats, egg yolks, shellfish, and full-fat dairy are among the foods highest in cholesterol. A single chicken liver serving packs 631 mg, and one egg contains 212 mg. But the cholesterol in your food and the cholesterol in your blood are not the same thing, and understanding which foods actually raise your blood cholesterol levels matters more than memorizing a list of numbers.
Foods With the Most Cholesterol
Cholesterol is found only in animal products. Plant foods, including oils, beans, nuts, and tofu, contain zero. Here are the biggest sources, measured in milligrams per serving:
Organ meats top the list by a wide margin. Chicken liver contains 631 mg per 3.5-ounce serving, and beef liver has 389 mg. These are the most cholesterol-dense foods you can eat.
Shellfish and squid are surprisingly high. Squid delivers 231 mg per 3.5 ounces, and shrimp comes in at 194 mg. Crab (52 mg), oysters (55 mg), and lobster (71 mg) are more moderate.
Eggs are the most commonly eaten high-cholesterol food. One whole egg has 212 mg, nearly all of it in the yolk.
Red meat varies by cut. Beef short ribs have 94 mg per 3.5 ounces, sirloin has 89 mg, and lean ground beef has 78 mg. Lamb and veal are similar, with veal top round reaching 135 mg. Pork and chicken without skin hover around 79 to 85 mg.
Dairy adds up through portion size. Whole milk has 33 mg per cup, cheddar cheese has 30 mg per ounce (and most people eat more than an ounce at a time), and butter contributes 11 mg per teaspoon. Switching to nonfat milk drops you to just 4 mg per cup.
Dietary Cholesterol vs. Blood Cholesterol
Here’s the part most people get wrong: the cholesterol you eat is not the main driver of the cholesterol levels in your blood. A randomized crossover study found that blood levels of LDL (the “bad” cholesterol) were significantly related to how much saturated fat people ate, but not to how much dietary cholesterol they consumed. Saturated fat, not dietary cholesterol, is what elevates LDL.
That distinction matters practically. Shrimp is high in cholesterol (194 mg) but very low in saturated fat, so it has minimal effect on your blood cholesterol. A cheeseburger may have less cholesterol on paper, but the combination of saturated fat from the beef and cheese does more to push your LDL upward. This is why nutrition advice has shifted over the past decade. The federal dietary guidelines used to cap cholesterol at 300 mg per day but now simply recommend keeping it “as low as possible without compromising the nutritional adequacy of the diet.”
Your liver produces the majority of the cholesterol circulating in your blood. When you eat more cholesterol, your body typically compensates by producing less. That system works reasonably well in most people, which is why dietary cholesterol has a weaker effect on blood levels than saturated fat does.
The Egg Question
Eggs are the flashpoint of the dietary cholesterol debate because they’re high in cholesterol but also packed with protein, vitamins, and other nutrients. The American Heart Association’s current position is that healthy people can include up to one whole egg per day, and older adults with normal cholesterol levels can have up to two.
For most people, eating an egg a day does not appear to increase heart disease risk. A large meta-analysis published in The BMJ found no significant association between eating one egg daily and cardiovascular disease in people without diabetes. However, the picture looks different for people with type 2 diabetes: pooled data suggested that higher egg consumption could raise cardiovascular risk in that group by roughly 25 to 40 percent. The likely explanation is that insulin resistance disrupts the body’s ability to regulate cholesterol production and clearance, so extra dietary cholesterol has a bigger impact.
What Counts as High Blood Cholesterol
Since high cholesterol in your blood produces no symptoms at all, the only way to know your levels is through a blood test. Total cholesterol below 200 mg/dL is considered normal. Between 200 and 239 is borderline high, and 240 or above is high.
LDL cholesterol is the number most closely tied to heart disease risk. Below 100 mg/dL is optimal. Between 130 and 159 is borderline high, 160 to 189 is high, and anything at 190 or above is very high. HDL, the protective type of cholesterol, should ideally fall between 60 and 80 mg/dL. Below 40 in men or 50 in women is considered too low.
For children and teens (age 19 and under), the thresholds are lower. Total cholesterol should be under 170 mg/dL, and LDL should be under 110 mg/dL.
Why High Blood Cholesterol Is Dangerous
When LDL cholesterol stays elevated over time, fatty deposits called plaque build up inside your artery walls. This gradually narrows the arteries, reducing blood flow. If the arteries supplying your heart are affected, you may develop chest pain during exertion. If plaque ruptures, a blood clot can form at the site and block the artery entirely, causing a heart attack. The same process in arteries leading to the brain causes stroke.
The dangerous part is the timeline. Plaque accumulates silently over years or decades. There is no pain, no warning, and no way to feel it happening. Many people discover they have high cholesterol only after a cardiac event, which is why routine blood testing matters even when you feel perfectly fine.
Foods That Lower Blood Cholesterol
If your goal is to bring your numbers down, focusing on what you add to your diet is just as important as what you remove. Soluble fiber, found in oats, beans, lentils, and fruits like apples and citrus, binds to cholesterol in your gut and helps your body excrete it. Replacing saturated fats (butter, fatty cuts of meat, full-fat cheese) with unsaturated fats from olive oil, avocado, nuts, and fatty fish like salmon has a direct LDL-lowering effect.
Plant-based proteins are naturally cholesterol-free. A half-cup of pinto beans or tofu contains 0 mg of cholesterol and no saturated fat. You don’t need to eliminate animal products entirely, but shifting the balance toward more plant foods and fewer processed or fatty meats is one of the most effective dietary changes you can make. Margarine and vegetable oils also contain zero cholesterol, compared to 11 mg per teaspoon of butter, which adds up quickly when you cook with it daily.
