Despite being low in calories, shrimp contains many nutrients, including iodine and antioxidants, that may offer health benefits. But it is high in cholesterol.
Many nutrients are found in high amounts in this food, including iodine, which isn’t found in many other foods.
On the other hand, some people claim that shrimp is unhealthy due to its high cholesterol content.
Additionally, it’s commonly believed that farm-raised shrimp may have some negative health effects compared with wild-caught shrimp.
This article explores the evidence to determine if shrimp is a healthy food to include in your diet.
It’s quite low in calories, providing only 84 calories in a 3-ounce serving (1).
Additionally, the same serving size provides more than 9 different vitamins and minerals (1).
Here’s an overview of the nutrients in a 3-ounce (85-gram) serving of shrimp (1):
Also, shrimp is one of the best foods to get iodine, which is a mineral that many people don’t get enough of. Iodine is required for proper thyroid function and brain health (2).
Shrimp is also a good source of omega-3 fatty acids (3).
A lot of people are afraid of high-cholesterol foods because they think they raise the cholesterol level in your blood and make you more likely to get heart disease.
But studies show that this might not be true for most people, since only 25% of people are sensitive to dietary cholesterol. For the rest, dietary cholesterol may only have a small impact on blood cholesterol levels (4).
This is because your liver makes most of the cholesterol in your blood, and when you eat foods high in cholesterol, your liver makes less of it.
What’s more, shrimp contains several nutrients that may actually boost health, such as omega-3 fatty acids (3).
Studies show that shrimp is one of the few foods that is not high in both cholesterol and saturated fats.
Even though more research is needed to fully understand shrimp’s impact on heart health, it does have many health benefits that may outweigh the cholesterol it contains.
Astaxanthin is a component of algae, which is consumed by shrimp. For this reason, shrimp is a major source of astaxanthin. In fact, this antioxidant is responsible for the reddish color of shrimp cells (7).
When you consume astaxanthin, it may help protect against inflammation by preventing free radicals from damaging your cells. It’s been studied for its role in reducing the risk of several chronic diseases (7).
Shrimp is one of the most popular seafood options loved for its succulent and sweet flavor profile. This versatile shellfish can be prepared in endless ways, lending itself beautifully to cuisines across the globe. But when it comes to nutrients many people wonder – is shrimp high in potassium?
As a key mineral, potassium plays diverse roles in supporting our overall health and wellbeing Understanding shrimp’s potassium content can help determine if and how it fits into a well-balanced, nutrient-rich diet.
In this in-depth article, we’ll explore all aspects of shrimp’s potassium levels, how it compares to other foods, and what it means for your health. Let’s dive right in and uncover everything you need to know about potassium and shrimp.
An Overview of Potassium and Its Health Benefits
First, let’s start with a quick primer on why potassium matters in the first place.
Potassium is an essential mineral that serves many crucial functions in the body. It plays a key role in:
- Regulating fluid balance and hydration
- Supporting proper muscle and nerve function
- Maintaining normal blood pressure
- Preserving bone health
- Assisting metabolic processes
Research shows that meeting your recommended daily potassium intake is associated with reduced risk of heart disease, strokes, kidney stones and osteoporosis. Overall, adequate potassium levels are linked to better cardiovascular health and wellness.
The recommended daily intake for potassium is 4700 milligrams for adults. While deficiency is rare, many people fall short of optimal intake levels. Boosting your potassium consumption from natural food sources can provide a health boost.
Evaluating the Potassium Content in Shrimp
Now that we’ve covered why potassium matters, let’s evaluate how shrimp fits into the picture. Here’s a detailed breakdown of shrimp’s potassium profile:
- A 3 ounce serving of shrimp contains about 145 milligrams of potassium.
- Shrimp’s potassium content is considered relatively low compared to many other protein foods.
- Potassium levels can vary slightly depending on shrimp type and size. But differences are minimal.
- Shrimp provides a moderate potassium kick while remaining low in calories, fat and carbs.
- Pairing shrimp with potassium-rich sides can help meet daily needs.
In comparison to other high potassium foods, shrimp is not a significant source. For instance, 1 banana contains about 400mg potassium and 1 avocado has over 1000mg.
However, shrimp still offers a potassium boost and contributes to your overall daily intake. Coupled with its stellar nutrition profile, it makes a valuable diet addition.

Heart and brain health
Many studies have found astaxanthin may help strengthen arteries, which may reduce the risk of heart attacks. It may also help increase levels of high-density lipoprotein (HDL), or “good” cholesterol, an important factor in heart health (8).
In addition, astaxanthin may be beneficial for brain health. Its anti-inflammatory properties may prevent damage to your brain cells that often leads to memory loss and neurodegenerative diseases, such as Alzheimer’s (7).
Even with these results, more studies on humans are needed to find out what effect astaxanthin in shrimp may have on health in general.
Due to the high demand for shrimp in the United Sates, it’s often imported from other countries.
Between 75 and 80% of the seafood eaten in the United States is imported from other countries, like Thailand, China, Canada, Indonesia, and Vietnam (9).
Although this helps increase access to shrimp, most imported shrimp is farm-raised, which means it’s grown in industrial tanks that are submerged in bodies of water (10).
Farm-raised seafood from other countries is frequently treated with antibiotics due to its high susceptibility to disease. However, the United States does not permit the use of antibiotics in shrimp and other shellfish (10).
For this reason, it’s illegal to import shrimp that contains antibiotics. The Food and Drug Administration (FDA) is responsible for inspecting imported shrimp to ensure it doesn’t contain antibiotics (11).
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 U.S. food supply (12).
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 diseases that do not respond to antibiotic treatment (13).
If you are worried about antibiotics in shrimp, choose wild-caught shrimp instead. These shrimp are never given antibiotics. Additionally, you can be assured that shrimp caught and prepared in the United States does not contain antibiotics.
Shellfish, including shrimp, are classified as one of the top nine food allergies in the United States, along with fish, peanuts, tree nuts, wheat, milk, and soy (14).
The most common trigger of shrimp allergies is tropomyosin, a protein found in shellfish. Other proteins in shrimp that may trigger an allergic reaction include arginine kinase and hemocyanin (15).
Symptoms of shellfish allergy
Symptoms of shrimp allergies vary and may include (16):
- tingling in the throat
- digestive issues
- breathing difficulties
- skin reactions
Some people with shrimp allergies may have anaphylactic reactions, as well. This is a dangerous, sudden reaction that can lead to seizures, unconsciousness, and even death if it is not treated immediately (16).
If you’re allergic to shrimp, the only way to prevent allergic reaction is to completely avoid eating it.
In some instances, even the vapors from cooking shrimp can trigger a reaction. So, those with shrimp allergies must also avoid situations where they may be exposed to it indirectly (16).
It’s important to choose high quality, fresh shrimp that isn’t damaged, infected, or contaminated.
When purchasing raw shrimp, make sure they’re firm. The shells should be translucent and grayish-green, pinkish tan, or light pink in color. Blackened edges or black spots on the shells may indicate quality loss (17).
Additionally, raw and cooked shrimp should have a mild, “ocean-like” or salty smell. Shrimp with an overwhelming “fishy” or ammonia-like odor is likely spoiled and unsafe to consume.
You should only buy shrimp from a reputable and knowledgeable seller who can answer your questions about where the shrimp came from and how it was handled.
