Gout is a type of arthritis that occurs when too much uric acid is in the blood. Uric acid is a waste product produced when the body breaks down a molecule called purine. Purines are nitrogen-containing organic building blocks found in the cells of all living things. Too much uric acid in the blood can form tiny, sharp crystals in the joints. These crystals can cause redness, inflammation and intense pain, which are symptoms of gout.
A gout attack can be very painful. Most commonly, gout affects the big toe joint. However, it can also affect a person’s ankles, knees or wrists. Walking can be challenging if gout happens in the toe, ankle or knee.
Shrimp is one of those foods that seems to spark debate among those with gout. Some claim it’s a food to avoid due to its high purine content, while others say it’s fine to eat in moderation. So what’s the real deal – is shrimp high in uric acid?
As someone who has suffered from gout attacks for years I’ve done extensive research on diet and gout. I’ve experienced firsthand the agonizing pain of gout flares and have learned to carefully follow a low-purine diet to prevent recurrences. However, as much as I love shellfish, I’ve had to mostly avoid shrimp due to concerns over its purine content.
In this article, I’ll share what I’ve learned from both personal experience and trusted sources on whether shrimp truly is high in uric acid. I’ll also provide some tips on how those with gout can still enjoy shrimp occasionally without triggering painful flares.
A Quick Gout Refresher
Before diving into shrimp specifically, let’s do a quick recap on gout and diet. Gout is a form of inflammatory arthritis caused by a buildup of uric acid crystals in the joints. This leads to redness, swelling, heat, and excruciating pain in joints, often the big toe.
Uric acid comes from the breakdown of purines. Purines are natural substances found in many foods, with higher amounts in certain meats, seafood, and alcohol.
For those prone to gout, consuming high-purine foods can raise uric acid levels. This causes crystals to form and deposit in joints, resulting in a gout attack. Avoiding purine-rich foods and managing uric acid levels through medication can prevent recurrent gout flares.
Now that we’ve reviewed the role of purines and uric acid in gout, let’s see how shrimp fits into the picture.
Evaluating the Purine Content of Shrimp
When it comes to gout-safe eating, purine content is the main factor to evaluate in foods. Below 100 mg per 100g is considered low-purine, 100-200 mg per 100g moderate, and over 200 mg per 100g high. Foods under 100 mg are generally safe, while high-purine foods above 200 mg should be avoided.
Let’s look at the purine levels in shrimp, according to reputable sources:
-
Healthline: 146 mg in 147g (100g)
-
Canadian Science Publishing: 142 mg in 100g
-
Arthritis Foundation: 142 mg in 100g
Based on these figures from trusted health sites and studies, shrimp contains about 140-150 mg of purines per 100g. This places it in the moderate purine range.
So while not extremely high in purines, shrimp cannot be considered low-purine either. This means that those prone to gout flares may need to eat shrimp in moderation or avoid it altogether during acute attacks.
Additional Factors that Influence Uric Acid Levels
While the purine content of shrimp lands it in the moderate range, there are some other factors that can influence uric acid levels as well:
1. Cooking method: Boiling shrimp instead of frying reduces the purine content slightly. Frying locks in more purines, while boiling releases some purines into the cooking liquid.
2. Serving size: Obviously eating a serving of 16 jumbo shrimp has higher purines than 4 small shrimp. Pay attention to serving sizes.
3. Individual factors: Each gout sufferer has their own threshold for triggers. Some do fine with moderate purine foods while others have to stick to low-purine fare only. Know your body.
4. Alcohol: Consuming alcohol, especially beer, raises uric acid. Avoid drinking alcohol around the time you eat shrimp.
5. Medications: If you are on uric-acid lowering medications, you may tolerate moderate purine foods better than someone who isn’t. Discuss diet with your doctor.
So essentially, the impact shrimp has on your uric acid levels depends on a combination of its purine content, how it’s prepared, how much you eat, and your individual gout profile. Let’s look at what this means for your diet.
How to Include Shrimp in a Gout-Friendly Diet
Now that we’ve determined shrimp sits in the moderate purine range, where does it leave those with gout who want to enjoy this tasty seafood? Here are some tips on eating shrimp with gout:
-
If shrimp is a known trigger for you, avoid it during acute attacks and periods of high disease activity. Focus on low-purine foods under 100 mg instead.
-
If you tolerate moderate purine foods well, enjoy shrimp in moderation by limiting portion sizes. Stick to 2-3 ounces a few times per month.
-
Choose boiled shrimp over fried, and avoid pairing it with alcohol.
-
Balance intake of higher purine shrimp with lower purine foods like plants, dairy, eggs, and purine-free fish.
-
Take any prescribed uric-acid lowering medications consistently to improve your tolerance. Discuss any diet changes with your doctor.
-
Pay attention to your body’s signals. If shrimp consumption correlates with attacks, avoid it. But if it doesn’t trigger flares, you may be able to enjoy it more liberally.
The Verdict on Shrimp and Gout
So, after analyzing the evidence, research and expert advice on shrimp’s purine content, what’s the final verdict?
Shrimp cannot be considered a low-purine gout food, with around 140-150 mg purines per 100g portion. However, it falls in the moderate vs. high range, so some shrimp can be part of a gout diet if intake is managed.
The impact shrimp has on uric acid will depend on the individual. Gout sufferers should start conservatively with very limited shrimp intake, and see if it correlates with attacks. For those who aren’t bothered by moderate purine shrimp, enjoying a few ounces here and there along with a predominately plant-based, low-fat, low-sugar diet is reasonable.
However, those with frequent gout attacks or who find shrimp is a reliable trigger should avoid it altogether and focus on safer seafood choices, like certain fish and mollusks lower in purines. Using cooking methods like boiling and limiting portions can also reduce purine intake from shrimp for those who wish to eat it occasionally.
While shrimp contains nutrients like protein, calcium, iron, and minerals, it simply isn’t worth enduring the excruciating pain and disability of a gout flare. By managing gout through a combination of medications, healthy eating, and avoiding your unique food triggers, you can reduce attacks and still enjoy a varied, balanced diet with the occasional indulgence.
My hope is that this analysis provides some clarity on the confusing debate about whether shrimp is high in uric acid. While not extremely purine-rich, shrimp intake requires some caution and moderation for those prone to gout attacks. Pay attention to your own body’s signals, consult your doctor, and enjoy the many low and moderate purine food options available to craft a gout-friendly eating plan with the occasional shrimp dish if tolerated. With a carefully managed diet, you can keep gout symptoms under control and enjoy life to the fullest.
7 Foods That Trigger Gout
A buildup of uric acid in the blood causes gout. Uric acid is the waste product the body creates when it breaks down a substance called purines. Many foods contain purines, including meats, seafood and foods containing high fructose corn syrup and alcohol. Additionally, when the body processes sugar or fructose, they release purines and cause uric acid levels to rise.
If you have gout, staying away from foods that are high in purines will help lower your uric acid levels and lower your risk of having an attack.
- Red meats: Beef, pork, lamb, bacon, veal, and deer are all red meats that are high in purines. A person with gout should limit eating red meat.
- Organ meats: Heart, kidney, liver, and other organ meats are very high in purines. If you have gout, you should limit or stay away from these foods.
- Foods that come from shells: lobster, crab, shrimp, scallops, mussels, and more are high in purines. Seafood, like sardines, anchovies, codfish, herring, haddock, and trout, is also high in purines. People with gout need to trim down on shellfish and some seafood to avoid flare-ups.
- Drinks that are high in sugar: Soda and fruit juices, as well as other drinks with natural or added sugar, can make gout attacks more likely.
- HFCS: Sweets like candy, pastries, and other sweets have a lot of purines. People with gout should limit the foods they eat that have high fructose corn syrup.
- Fruits: Some fruits are bad for gout. Apples, oranges, and dates are all fruits that naturally have a lot of fructose. Avoid high fructose-containing foods.
- Alcohol: Beer and other alcoholic drinks can make gout attacks more likely. The level of uric acid in the body goes up when it breaks down alcohol. Beer is high in purines. A person with gout needs to limit alcohol consumption.
How Is Gout Diagnosed?
Medical providers diagnose gout based on symptoms, medical history, physical exam, imaging and lab tests. A specialty doctor called a rheumatologist can treat gout.
A rheumatologist will help lower uric acid levels with medications if indicated. People who have gout can help stop future attacks and make flare-ups less painful by changing their diet and staying away from foods that are high in purines.
People who suffer from gout experience symptoms similar to arthritis, paired with systemic or whole-body symptoms.
- Sudden, severe pain in a joint
- Inflammation, redness and warmth in the affected joint
- Tenderness: the joint is tender to the touch
- Fever: a temperature greater than 100.4 F
Gout treatment typically involves taking medication to lower uric acid levels in the blood and reduce joint inflammation. Dietary changes are a big part of the treatment plan. Diet changes can help to prevent further gout attacks. Maintaining a healthy weight and limiting alcohol can also help prevent gout flare-ups.
