Can Seafood Cause High Cholesterol?

Upon examining the scientific studies, it turns out that seafood does not cause bad cholesterol. The cholesterol present in shrimp does not exert a direct effect on the cholesterol levels in the blood.

We know that shellfish, including shrimp and squid, naturally contain more cholesterol compared to other food items, yet does this imply that it elevates an individual’s cholesterol levels? 

Let’s explain why.

Is seafood bad for high cholesterol?

No! Seafood, particularly fish, is generally suitable for individuals managing high cholesterol levels. Fish is low in saturated fat, which is beneficial for heart health, and health professionals advocate its consumption. 

Oily fish, due to their omega 3 fatty acids, can help prevent heart disease. Shrimp, although low in fat, is indeed rich in cholesterol. However, the majority of studies indicate that the health benefits of consuming shrimp surpass the potential downsides. 

When considering the cholesterol content in seafood, it’s important to note that all fish have some cholesterol, but this shouldn’t be a cause for concern. Different types of seafood contain varying levels of cholesterol.

For example, fish like tuna and salmon are not only lower in cholesterol but are also abundant in Omega 3 fatty acids, which aid in lowering cholesterol levels. 

Also, shellfish such as clams, crab, and shrimp are good sources of protein, B vitamins, iron, and selenium. The American Heart Association suggests opting for fatty fish like salmon, anchovies, herring, and others, given their health benefits. 

Hence, while shrimp and other seafood do contain cholesterol, they also offer essential nutrients that can support heart and cardiovascular health, making them a valuable part of the diet.

Which seafood has the highest cholesterol?

Among different types of seafood, squid has the most cholesterol per serving. In a 3.5-ounce (99 grams) portion of raw squid, you’ll find approximately 231 mg of cholesterol. 

This amount may surpass the recommended daily cholesterol intake, especially if you’re following a doctor-prescribed diet limiting cholesterol to under 200 mg per day. 

Remember, how the seafood is cooked—whether it’s fried, sautéed, or grilled—can also affect the final cholesterol content.

Here’s a breakdown of the cholesterol and total fat content in some common seafood choices (per 3.5 oz of raw seafood):

  • Squid: It’s the cholesterol king of the sea at 231 mg. But on the flip side, it’s pretty lean with just 1 gram of fat.
  • Shrimp: Close contender with 194 mg of cholesterol. Also, it is lean, mean, and just 1 gram of fat.
  • Lobster: A fancier choice with less cholesterol at 71 mg, and keeps it light with 1 gram of fat.
  • Salmon: The popular one is not just tasty but also has a decent cholesterol level at 63 mg and brings more fat to the party, 12 grams, but it’s the good kind that your body gives a thumbs up to.
  • Oysters: These little guys pack 55 mg of cholesterol and just 2 grams of fat. Plus, they’re zinc superstars.
  • Crab: They’re walking the seabed with 52 mg of cholesterol and 1 gram of fat. Crab cakes, anyone?
  • Halibut: The lean, mean white fish has 41 mg of cholesterol and a bit more fat at 3 grams.
  • Tuna: The lunchtime favorite, lowest in cholesterol at 30 mg and keeps it tight with 1 gram of fat

What are the worst foods for high cholesterol?

If you’re looking to manage high cholesterol, it’s advisable to cut down on foods rich in saturated fats, aiming for these to constitute less than 10% of your daily caloric intake. 

Let’s get straight about the foods that might be messing with your cholesterol.

  1. Red meats & processed meats – Like grabbing a burger or a slice of pepperoni pizza? These are the taste temptations you might want to rethink. They’re filled with the kind of fats that make your cholesterol unhappy.
  2. Full-fat dairy products – We’re looking at you, creamy ice cream and cheesy pizza. Delicious, yes, but sneaky sources of those saturated fats we’re trying to avoid.
  3. Baked items & sugary treats – Cookies, cakes, pastries; they’re not just sugar bombs. They’re often loaded with saturated fats, too. Enjoy them, but remember they’re treats, not staples.
  4. Deep-fried foods – Those crispy fries and golden chicken wings are hard to resist. But they’re dunked in oil that’s heavy on the bad fats.
  5. Tropical oils (palm & coconut oil) – They may sound exotic and healthy, but when it comes to cholesterol, they’re not doing you any favors.
  6. Butter – A little on toast might be fine, but butter is essentially concentrated saturated fat, so tread lightly.

What has more cholesterol eggs or shrimp?

Shrimp, compared to other protein sources like chicken, mutton, beef, pork, and eggs, has a relatively low concentration of saturated fatty acids, which are known to increase blood cholesterol levels.

Specifically, shrimp contains only 0.25 mg of saturated fatty acids per 100 g. When it comes to cholesterol content, shrimp has 173 mg per 100 g, which is significantly less than the 400 mg found in the same amount of eggs.

So, regarding the cholesterol content comparison between eggs and shrimp, an egg has a higher cholesterol level, with 372 mg per 100 grams, while shrimp contains 66% less, at 126 mg per 100 grams.

To put it into perspective, fifteen large shrimp provide roughly 175 mg of cholesterol, which is just shy of the amount found in one whole egg.

Shrimps have more cholesterol than an egg!

Shrimp, while recognized for their high cholesterol content at approximately 130 milligrams, maintain a low fat profile with just 2 grams per serving. These crustaceans are not only a robust source of B vitamins and protein but are also rich in selenium and zinc, essential nutrients for overall health.

It’s generally acceptable to indulge in shrimp once or twice a week, but it’s advisable to consult with a healthcare provider. Moreover, shrimp are abundant in unsaturated fatty acids, which are beneficial in elevating HDL, the “good” cholesterol levels.

Comparatively, other seafood, such as crab and octopus, fall into the same low-fat category but contain even less cholesterol than shrimp. The most favorable options in terms of cholesterol and fat content are clams, mussels, oysters, and scallops, which boast both low-cholesterol and low-fat benefits.

A hidden secret about cholesterol regulation

Seafood is your heart’s ally, not its enemy. Contrary to popular myth, dietary cholesterol from seafood, such as delicious shrimp, does not sabotage your plasma cholesterol levels.

In fact, the body is a cholesterol-regulating marvel, adept at adjusting its own production based on dietary intake. Seafood, with minimal saturated fats and abundant omega-3s, reigns supreme in heart health, actively lowering LDL cholesterol and triglycerides.

Fiber regulates cholesterol. Finding it tough to meet your fiber goals? A psyllium fiber supplement can plug the gap. The soluble fiber, found in eats like oats, barley, citrus fruits, and eggplant, is your heart’s ally, slashing bad cholesterol levels. To reap these benefits, aim for 21 to 38 grams of fiber daily.

Do seafood and fiber lower your cholesterol?

Yes, seafood and fiber can indeed help lower your cholesterol. The omega-3 fatty acids present in seafood such as salmon and tuna are known to lessen inflammation and lower the levels of triglycerides in the bloodstream. Such advantages aid in promoting better health for the heart.

Also, soluble fiber, which is available in foods like kidney beans, Brussels sprouts, apples, and pears, can help decrease cholesterol absorption into your bloodstream.

Consuming at least 5 to 10 grams of soluble fiber daily is associated with a reduction in LDL cholesterol, the type that’s often referred to as “bad” cholesterol.


To conclude, seafood is an excellent dietary choice for those managing high cholesterol. Rich in omega-3 fatty acids and low in saturated fat, fish such as salmon and tuna promote heart health by reducing inflammation and triglycerides. While shrimp is higher in cholesterol, its overall health benefits outweigh concerns. Embrace the heart-healthy benefits of seafood and incorporate it into your cholesterol-conscious diet with confidence.
