Shrimp are a popular type of seafood that are enjoyed around the world. Shrimp consist of an edible meaty part as well as an outer shell and legs. A common question that arises when eating shrimp is whether the shell and legs are also edible or should be discarded.
Can You Eat Shrimp Shells?
The shrimp shell is made up of a thin outer layer called the exoskeleton. This shell is composed primarily of chitin, which is a fibrous substance that does not readily break down during digestion. Chitin is the same material that makes up the hard outer skeletons of insects and crustaceans.
While chitin is not toxic, the human digestive system cannot easily break it down. Eating moderate amounts of shrimp shells may be okay, but eating too much can cause digestive issues. The shell acts as a fibrous material that does not provide much nutritional value and can potentially cause constipation, diarrhea or an upset stomach if large quantities are consumed.
For this reason, it is generally recommended to remove the shell before eating shrimp. Peeling raw shrimp or buying peeled and deveined shrimp can help avoid any digestive discomfort from consuming the shell.
Pros of Eating Shrimp Shells
Although shrimp shells are indigestible, some people do choose to eat them anyways. Here are some of the pros associated with eating shrimp shells:
- Provides extra fiber – While our bodies cannot digest chitin, it does provide some extra fiber, which promotes digestive health.
- Contains calcium – Shrimp shells contain a decent amount of calcium, about 150-200 mg per 3 oz serving.
- Contains antioxidants – Astaxanthin, a beneficial antioxidant, gives shrimp shells their reddish color.
- Adds texture – The crunch from shells can provide an interesting textural contrast.
- Adds flavor – Some people enjoy the mild seafood flavor imparted by shrimp shells.
Cons of Eating Shrimp Shells
On the other hand, here are some of the downsides of consuming shrimp shells:
- Indigestible – Chitin cannot be broken down and absorbed by the body.
- GI distress – Too much shell can cause constipation, diarrhea, bloating, gas and cramps.
- Difficult to chew – Shells require more chewing and can be awkward to eat.
- Easy to choke on – Shell pieces can potentially pose a choking risk for some.
- Unpleasant texture – Shells have a dry, papery crunch that some find unappealing.
Can You Eat Shrimp Legs?
Like the shell, shrimp legs are also made of chitin and are not easily digested. However, the legs do contain a bit more meat than the main shell. The meaty portion of the legs will provide some nutritional value, while the indigestible chitin portion will act as fiber.
Many people choose to eat the upper meatier portion of shrimp legs and discard the very bottom part where it is mostly shell/chitin. The legs can provide a nice crunch and seafood flavor, just be wary of eating too much of the shell portion.
Pros of Eating Shrimp Legs
- Contains meat – Upper legs have some edible meat similar to the shrimp body.
- Crunchy texture
- Added flavor
- Fiber from chitin
- Nutrients like protein, calcium, antioxidants
Cons of Eating Shrimp Legs
- Indigestible chitin
- GI issues if eating too much shell
- Annoying to pick out of teeth
- Choking hazard
Final Verdict: Okay in Moderation
Overall, eating moderate amounts of shrimp shells and legs should be safe for most people, as long as it is thoroughly chewed. While the chitin provides fiber and some nutrients, too much can lead to digestive upset. Here are some final guidelines for safely consuming shrimp shells and legs:
- Peel and devein shrimp to remove inedible parts if desired
- Chew the shells and legs thoroughly to prevent choking/GI issues
- Limit shells and legs to a few pieces per serving
- Avoid giving small children whole shrimp with shells and legs due to choking risk
- Remove legs from shrimp before giving to elderly people or those with dental issues
- Stop eating shells/legs if you experience any digestive discomfort
While not as ideal as the fleshy part of the shrimp, the shells and legs can be consumed safely as part of a normal shrimp eating experience. Just be cautious of overdoing it on the crunchy bits, and enjoy shrimp in moderation as part of a healthy, well-balanced diet.
Nutritional Profile of Shrimp Shells vs. Meat
Here is a comparison of the nutritional profiles of shrimp meat versus shrimp shells per 100g serving:
As shown, shrimp meat provides more protein and overall calories compared to the shell. The shell is higher in fiber, calcium and iron content.
Tips for Preparing and Cooking Shrimp
Here are some tips for getting the most out of your shrimp when cooking and eating:
- Buy peeled & deveined shrimp – This avoids having to deal with the shells and veins.
- Leave tails on – The tails contain meat and add visual appeal without posing a choking risk.
- Butterfly shrimp – Cutting along the back and flattening exposes more surface area for sauces and seasoning.
- Marinate before cooking – Letting shrimp soak up flavors before cooking infuses more taste.
- Don’t overcook – Shrimp gets tough and rubbery when cooked too long. Cook just until pink.
- Try grilling – Grilled shrimp infused with smoke flavor is delicious.
- Bake breaded shrimp – Coat with breadcrumbs and bake for a crispy crunch.
Properly preparing shrimp helps make them tender and infused with flavor. Experiment with different cooking methods and seasonings to enhance the shrimp eating experience.

Health Benefits of Shrimp
In addition to being delicious, shrimp offer many health benefits:
- High in protein – Great source of lean protein needed for muscle growth and function.
- Low fat – Compared to other high protein foods like red meat, shrimp are low in saturated fat.
- Good source of selenium – Selenium supports thyroid and immune system function.
- Contains antioxidants – Astaxanthin provides antioxidant and anti-inflammatory effects.
- Rich in vitamins/minerals – Packed with immune-boosting zinc, iodine, copper and B-vitamins.
- Heart healthy omega-3s – Omega-3 fatty acids reduce inflammation and lower heart disease risk.
Consuming shrimp offers nutrients that protect overall health, making them a great addition to a healthy diet. Just be mindful of preparation methods, like deep frying, that can add extra calories and fat.
Risks and Precautions with Eating Shrimp
While shrimp offer many benefits, there are also some precautions to keep in mind:
- Allergies – Some people are allergic to shellfish. Discontinue eating if any hypersensitivity reaction occurs.
- High cholesterol – Shrimp contains higher amounts of dietary cholesterol, so moderation is key.
- Foodborne illness – Consuming undercooked or contaminated shrimp can cause food poisoning. Cook thoroughly.
- Heavy metal exposure – Shrimp obtained from contaminated water may contain heavy metals. Buy from reputable source.
- Interaction with medications – Shrimp may interact with blood thinner medications. Consult physician.
Pregnant women, young children and those with underlying medical conditions should take extra care consuming shrimp. As with any food, proper handling and preparation helps reduce any risks.
Sustainability and Environmental Impacts of Shrimp Fishing
The growing demand for shrimp has raised some concerns when it comes to sustainability and environmental impacts:
- Some shrimp fishing methods disturb ocean ecosystems and seabeds. More sustainable trawling and farming practices are being developed.
- Mangrove forests are often cleared to create shrimp farms, harming natural coastal ecosystems.
- Chemicals and effluent from shrimp farms can pollute coastal waters if not properly regulated.
- Imported farmed shrimp may have higher carbon footprint versus local wild-caught shrimp.
When buying shrimp, it is best to look for sustainability certifications from organizations like the Marine Stewardship Council, Aquaculture Stewardship Council or Best Aquaculture Practices to ensure shrimp were raised responsibly.
Shrimp shells and legs are made of chitin, a fibrous substance that humans cannot digest. While not toxic, consuming large quantities of shells and legs can cause digestive issues. The shell provides some fiber and nutrients like calcium, but the shrimp meat offers more protein and overall nutrition.
Eating moderate amounts of shells and legs along with the shrimp meat should be safe for most people. Just be sure to chew thoroughly and limit intake if you experience any GI discomfort. When preparing shrimp, you can peel/devein to remove shells or leave shells on a few pieces for texture. Shrimp can be enjoyed in various cuisines and provide healthy protein, vitamins and omega-3s when consumed as part of a balanced diet.
