Cholesterol, often misunderstood, is a vital component of our cells. While the body produces it naturally, it’s also found in various foods. Understanding which foods are high in cholesterol and how they impact your health is essential for making informed dietary choices. Let’s explore some nutritious foods that contain significant levels of cholesterol.
1. Eggs: A Nutritional Powerhouse
Eggs are a highly nutritious food, offering a rich source of protein, vitamins, and minerals. Notably, they are also high in cholesterol. One large egg (50g) contains approximately 207mg of cholesterol.

Despite their cholesterol content, research suggests that eggs may not negatively impact cholesterol levels in the blood for most people. Some studies indicate that consuming whole eggs can even boost HDL (high-density lipoprotein) cholesterol, often referred to as “good” cholesterol. While some research suggests potential increases in LDL (low-density lipoprotein) cholesterol (“bad” cholesterol) with higher egg consumption, moderate intake, such as 1-2 eggs per day, is generally considered safe for healthy individuals.
2. Cheese: Calcium-Rich and Flavorful
Cheese is a beloved food enjoyed worldwide, providing calcium and other essential nutrients. A single slice (22g) of Swiss cheese contains about 20mg of cholesterol.

Interestingly, a 12-week study involving 139 participants revealed that consuming 3 ounces (80g) of full-fat cheese daily, considered a high intake, did not elevate LDL cholesterol compared to consuming the same amount of low-fat cheese or an equivalent caloric intake from bread and jam. This suggests that the impact of cheese on cholesterol may be more nuanced than previously thought.
3. Shellfish: A Seafood Delicacy
Shellfish, including clams, crab, and shrimp, are excellent sources of protein, B vitamins, iron, and selenium. A 3-oz (85-g) serving of canned shrimp contains 214 mg of cholesterol.

Despite their cholesterol content, research indicates that individuals who consume more seafood may experience improvements in cognitive, visual, and cardiovascular health. The beneficial omega-3 fatty acids and other nutrients in shellfish likely contribute to these positive health outcomes.
4. Pasture-Raised Steak: A Protein Powerhouse
Pasture-raised steak is a protein-rich food packed with essential vitamins and minerals. It’s also lower in cholesterol compared to feedlot beef and contains significantly more omega-3 fatty acids, which possess anti-inflammatory properties. A 4-oz (113-g) serving of pasture-raised steak provides approximately 62 mg of cholesterol.

Choosing pasture-raised steak over conventional beef can offer additional health benefits due to its superior nutrient profile.
5. Organ Meats: Nutrient-Dense Superfoods
Organ meats, such as heart, kidney, and liver, are incredibly nutritious and often overlooked. Chicken heart, for example, is an excellent source of CoQ10, a powerful antioxidant, as well as vitamin B12, iron, and zinc. A 1-cup (145-g) serving provides 351 mg of cholesterol.

A 2017 study involving over 9,000 Korean adults found that those with moderate intake of unprocessed meat, including organ meats, had a lower risk of heart disease compared to those with the lowest consumption. This suggests that incorporating organ meats into a balanced diet may offer protective cardiovascular benefits.
6. Sardines: Tiny Fish, Mighty Benefits
Sardines are nutrient-packed and a convenient source of protein. One 3.75-oz (92-g) serving contains 131 mg of cholesterol. They also provide 63% of the Daily Value (DV) for vitamin D, 137% of the DV for vitamin B12, and 35% of the DV for calcium.

The combination of cholesterol and essential nutrients in sardines makes them a valuable addition to a healthy diet.
7. Full-Fat Yogurt: A Probiotic Powerhouse
Full-fat yogurt is a cholesterol-rich food that provides essential nutrients. One cup (245 g) of full-fat yogurt contains 31.8 mg of cholesterol.

Research associates increased intake of full-fat fermented dairy products with reduced LDL cholesterol and blood pressure, along with a lower risk of stroke, heart disease, and diabetes. These benefits may be attributed to the probiotics and other beneficial compounds found in fermented dairy.
Conclusion
While these foods are high in cholesterol, they also offer a range of essential nutrients. Instead of avoiding them altogether, consider incorporating them into a balanced diet as part of a healthy lifestyle. The impact of dietary cholesterol on blood cholesterol levels is complex and varies among individuals. Consulting with a healthcare professional or registered dietitian can provide personalized guidance based on your specific health needs. Remember, a balanced approach to nutrition is key to overall well-being.
