Shrimp Is High In Cholesterol
Shrimp often gets a bad rap for its high cholesterol content.
A 3-ounce serving contains 166 mg of cholesterol. Thats almost 85% more than the amount of cholesterol in other types of seafood, such as tuna .
Many people fear foods that are high in cholesterol due to the belief that they increase the cholesterol in your blood, and thus promote heart disease.
However, research shows this may not be the case for most people, as only a quarter of the population is sensitive to dietary cholesterol. For the rest, dietary cholesterol may only have a small impact on blood cholesterol levels (
One study found that adults who ate 300 grams of shrimp daily increased their good HDL cholesterol levels by 12% and decreased their triglycerides by 13%. Both of these are important factors in reducing the risk of heart disease .
Another study found that 356 women who consumed shellfish, including shrimp, on a regular basis had significantly lower triglycerides and blood pressure levels compared to those who did not include shellfish in their diets .
Research has also shown that people who consume shrimp regularly do not have a higher risk of heart disease compared to those who do not eat it .
Although more research is needed to explore shrimps role in heart health, it has a variety of beneficial properties that may outweigh its cholesterol content.
Effect Of Eating Shrimps On The Cholesterol Level
As per a survey conducted, those who ate shrimps for around three weeks reported having a rise in their LDL cholesterol by about 7% compared to a low cholesterol diet.;
Simultaneously, it also increased the good cholesterol or HDL cholesterol by 12%, lowering the triglycerides by 13%. Thus, eating shrimp did not harm heart health, and in fact, it was helpful by raising the HDL cholesterol levels and contributing to a healthy heart.
The American Health Association has also claimed that shrimps contain Omega 3 fatty acids up to some extent. Omega 3 fatty acids are a type of healthful fat and benefit the cardiovascular system and other bodily functions.

What The Research Says
Since my patients often ask me about shrimp and cholesterol, I decided to review the medical literature and discovered a fascinating study from Rockefeller University. In 1996, Dr. Elizabeth De Oliveira e Silva and colleagues put a shrimp-based diet to the test. Eighteen men and women were fed about 10 ounces of shrimp supplying nearly 600 mg of cholesterol every day for three weeks. On a rotating schedule, the subjects were also fed a two-eggs-per-day diet, furnishing about the same amount of cholesterol, for three weeks. They were fed a baseline low-cholesterol diet for another three weeks.
After the three weeks were up, the shrimp diet did in fact raise LDL cholesterol by about 7 percent compared to the low-cholesterol diet. However, it also increased HDL, or good cholesterol, by 12 percent and lowered triglycerides by 13 percent. This reveals that shrimp had a total positive effect on cholesterol because it improved both HDL and triglycerides a total of 25 percent with a net improvement of 18 percent.
A 2015 study suggests that low HDL levels are associated with total inflammation in relation to heart disease. Therefore, a higher HDL is desirable.
The egg diet came out looking a worse, bumping up LDL by 10 percent while raising HDL only about 8 percent.
A Study On Shrimp Showed Surprising Results
One study showed that there is no reason to avoid this seafood. The researchers asked 18 men and women to eat large portions of steamed shrimp each day. To be precise, robust participants ate more than 275 grams, or 30 to 40 shrimp, which was enough to give them nearly 600 milligrams of dietary cholesterol. This is twice the daily limit recommended by the American Heart Association .
This may surprise you. Three weeks later, the researchers took blood samples from the volunteers and found that their levels of low-density lipoprotein or LDL or bad cholesterol had increased by 7.1% on average. While this may not seem like good news, shrimps have an important advantage; high-density lipoprotein levels or HDL, good cholesterol for arteries, increased by 12.1%. In other words, eating shrimp has improved the good cholesterol/bad cholesterol ratio. Many cardiologists believe that this ratio is a better indicator of cardiovascular health than total cholesterol levels.

Dietary Cholesterol And Heart Disease
Dietary cholesterol is only found in animal-based products. This includes meat and seafood, egg yolks and dairy products, including milk. It was once believed that eating foods high in cholesterol would raise the cholesterol levels in your body an increase your risk of cardiovascular disease. However, studies have not shown any link between dietary cholesterol and cardiovascular disease, notes Dr. Ghada Soliman in her review published in the June 2018 edition of Nutrients.
The 2010 Dietary Guidelines recommended limiting cholesterol to 300 milligrams per day. However, due to the lack of evidence that dietary cholesterol has negative health effects, this recommendation has been removed from the USDA’s current 2015 edition of the Dietary Guidelines for Americans.
There is a correlation between saturated fats and cardiovascular disease and saturated fats have been shown to increase your LDL cholesterol levels, advises Colorado State University Extension. Since many foods that are high in saturated fats are also high in cholesterol, it is a good idea to limit your intake of these foods. The 2015 Dietary Guidelines for Americans recommends getting less than 10 percent of your calories from saturated fats.

The Bottom Line On Shrimp And Cholesterol
If youve learned two things from this article on shrimp cholesterol levels it should be this:
1) There is no longer a daily dietary cholesterol limit because the government has finally realized that dietary cholesterol has minimal effect on your total cholesterol levels.
2) Shrimp may have a higher concentration of cholesterol than some other foods, but again, eating foods with high cholesterol does not translate to higher total cholesterol in your body. Thats a myth.
Shrimp are low in saturated fat, high in protein and packed with important vitamins and minerals. Unless you are allergic or have been advised to avoid them due to a medical condition, by all means indulge yourself. And the next time you see someone avoiding shrimp, or eggs, or meat because they are high in cholesterol, you can snicker knowing that they are depriving themselves unnecessarily.

Does Shrimp Have A Lot Of Cholesterol?
While its true that shrimp is a relatively high cholesterol food, thats not necessarily a bad thing. People with high cholesterol are advised to limit their intake of dietary cholesterol to 200 milligrams per day, and a serving of four large shrimp has 42.5 milligrams of cholesterol or 21% of the recommended cholesterol per day. So, if youre eating shrimp, you want to watch the other high-cholesterol foods youre eating that day.

Do I Need To Cut Down On Dietary Cholesterol
Most people dont need to cut down on the cholesterol thats found in foods- so you can still enjoy eggs and shellfish.
Its much more important to cut down on foods which contain saturated fats. Thats because saturated fats affect how the liver handles cholesterol. So, eating saturated fats can raise your blood cholesterol. Try to replace saturated fats with unsaturated fats which are better for your heart.
For some people; those with familial hypercholesterolaemia , those who have high cholesterol, and those who are at high risk of or have cardiovascular disease; the recommendation is to limit cholesterol in food to no more than 300mg a day. In the case of FH,;ideally less than 200 mg a day.
Even though dietary cholesterol only has a small effect on blood cholesterol, people with high cholesterol and FH already have high levels of blood cholesterol, so it seems sensible not to eat too much cholesterol in food.
Antibiotic Use In Farm
Due to the high demand for shrimp in the US, it is often imported from other countries.
More than 80% of the shrimp consumed in the US comes from abroad, from countries such as Thailand, India and Indonesia .
Although this helps increase access to shrimp, most imported shrimp is farm-raised, which means it is grown in industrial tanks that are submerged in bodies of water .
Farm-raised seafood from other countries is frequently treated with antibiotics due to its high susceptibility to disease. However, the US does not permit the use of antibiotics in shrimp and other shellfish .
For this reason, it is illegal to import shrimp that contains antibiotics. The US Food and Drug Administration is responsible for inspecting imported shrimp to ensure it doesnt contain antibiotics .
However, due to the high volume of shrimp imports, the FDA is unable to regulate all of them. Because of this, farm-raised shrimp contaminated with antibiotics has the potential to enter the US food supply .
One study that investigated the antibiotic content of US-purchased seafood found that a sample of farm-raised shrimp contained a detectable amount of sulfadimethoxine, an antibiotic not permitted for use in shrimp in the US .
Using antibiotics in shrimp has not been confirmed to have any major adverse health effects. However, it may lead to antibiotic resistance, which can cause outbreaks of disease that do not respond to antibiotic treatment .

Benefits Of Eating Shrimps For High Cholesterol
As mentioned above, shrimp is low in fats although the high cholesterol amount it contains.
What is more, shrimp are rich in unsaturated fatty acids, which are very beneficial to increase your HDL cholesterol levels. As you may see, if you eat shrimp, at the same time you may lower your blood cholesterol levels, and increase HDL levels too.
The ways you cook shrimp is important too. According to one study carried out from researches in Rockefeller University , although steamed shrimp increased blood cholesterol levels comparing to a low cholesterol diet; however shrimps increased the HDL cholesterol levels more than increasing LDL levels.
What is more, the HDL to LDL ratio was resulted favorable. Meanwhile, triglyceride levels were lower compared to the egg-based diet, which has the same content of cholesterol.
In addition, if you do follow any healthy diet, you can prepare dishes with shrimp cooked as broiled or boiled. At the same time, avoid or limit deep frying cooking method, reduce the amount of tartar sauce, butter, mayonnaise, and oil when cooking.
This is the best way to keep healthy and safe from any high cholesterol problems according to Thai Frozen Foods Association.
Which Foods Are High In Cholesterol

Full fat dairy foods such as milk, cheese, yogurt and cream.
Animal fats, such as butter, ghee, margarines and spreads made from animal fats, lard, suet and dripping.

Foods that contain cholesterol but are low in saturated fat.
Lean meat, especially offal, such as liver, kidney, sweetbreads, heart and tripe ;
Prawns, crab, lobster, squid, octopus and cuttlefish.
Eggs . ;
For people with FH, or who have high cholesterol, or are at high risk of or have cardiovascular disease, you can still eat some of these foods, but you need to be more careful about how often you eat them to ensure youre keeping within the guidelines. For example, you could eat three or four eggs a week, and shellfish such as prawns up to once or twice a week.
You should avoid liver and offal altogether because they are very rich sources of cholesterol.

How To Deal With Increased Cholesterol Levels
If you are dealing with highly increased cholesterol levels then you can undertake some medications as prescribed by the doctor and can make some lifestyle changes if you wish to bring it to normal levels.
- Statins are helpful in lowering your LDL levels and therefore preventing the clogging of arteries. It acts by slowing down the production of cholesterol by the liver.
- Apart from statins, you can also make use of cholesterol absorption inhibitors. These are responsible for blocking or inhibiting the absorption of cholesterol from the meals that you consume and are given sometimes in conjunction with the statins.
The use of bempedoic acid is also helpful in reducing your cholesterol levels. This acid prevents the formation of an enzyme called ATP citrate lyase in the liver and prevents the formation of cholesterol in the body. If you also exhibit a case of familial hypercholesterolemia then it can also be combined with statins to witness a better effect. This is a
- hereditary condition where the body is at risk of developing heart diseases.
- Bile acid sequestrants are also responsible for lowering blood cholesterol levels. These are used in digestion and they bind with bile acids to remove them. As this happens, the body begins to break down the LDL cholesterol to create bile acids.
- PCSK9 inhibitors are injected drugs that aid the liver to absorb LDL and remove excess of it from the blood. These are, however, most frequently used with familial hypercholesterolemia.
Risks And Benefits Of Seafood
Adding seafood to your diet may actually help improve your blood cholesterol levels. A study published in the November 2017 edition of Atherosclerosis found that consuming oily fish increased the “good”HDL cholesterol levels in the blood.
Seafood is a good protein source full of nutrients. It is especially known for having high omega-3 fatty acid content including both EPA and DHA, which decreases the risk of heart disease. The USDA recommends that adults eat eight ounces of seafood each week. Seafood may contain the heavy metal mercury, however, the health benefits of fish outweigh the risks of mercury consumption, advises the USDA.
Some low-mercury seafood options include:
Atlantic mackerel and Pacific mackerel
