Common Foods and Drinks to Avoid with Crabs
While a delectable treat, crab meat is best enjoyed with careful consideration of what accompanies it. Incompatible food and drink can lead to digestive upset or, in rare cases, more serious health issues. Understanding the chemistry behind these reactions is key to a safe dining experience.
Dairy Products
One of the most frequently cited food pairings to avoid is dairy. The high protein content in both fish and dairy can strain the digestive system when consumed together. This can result in bloating, gas, and stomach cramps. For individuals with lactose intolerance, these effects are even more pronounced. This incompatibility is why classic seafood boils rarely include milk or cheese and why rich, creamy bisques are made with stock instead of milk when served alongside crab.
High-Tannin Beverages (Tea and Certain Wines)
Tannic acid, found in tea and certain red wines, can interact with the high calcium and protein content in crab meat. This reaction can form compounds that are difficult for the body to digest, leading to irritation of the digestive tract. For this reason, it is often recommended to wait at least two hours after a seafood meal before drinking tea.
Fruits High in Vitamin C and Citric Acid
This is a food combination that, while often a source of flavor, should be approached with caution in large quantities. While a squeeze of lemon on crab is common, some traditional theories suggest that consuming high doses of vitamin C (e.g., from oranges, kiwi, or lemons) with seafood could pose a risk due to the presence of pentavalent arsenic. The theory posits that the vitamin C could convert this naturally occurring compound into a more toxic form. Although modern food safety standards have made this a less prevalent concern, moderation is still wise to avoid any potential for gastrointestinal discomfort caused by high acidity.
Excessive Alcohol
Consuming alcohol, especially beer, with a large amount of crab can be problematic for individuals prone to gout. Crab is a high-purine food, and alcohol intake can promote the conversion of purines into uric acid. An excessive accumulation of uric acid can lead to painful gout attacks in susceptible individuals. Moderation is key to prevent triggering a flare-up.
Certain "Cold-Natured" Foods (According to Traditional Medicine)
Based on traditional dietary beliefs in some cultures, seafood is considered a "cold-natured" food. Pairing it with other foods considered to have high "cold properties," such as watermelon, cucumber, or pears, is thought to cause digestive discomfort, bloating, and indigestion. While lacking a basis in modern science, this cultural wisdom serves as a good reminder to eat a balanced meal and not overindulge in heavy or watery foods at the same time.
Heavy Starches and Legumes
Consuming crabs with heavy, starchy foods like potatoes or pasta can overload the digestive system. Both crabs and legumes are rich in protein, and a combination can lead to gas and bloating. Eating a balanced meal with a lighter carb or vegetable side is often preferable for better digestion.
Important Safety Considerations Beyond Food Pairings
Beyond simple food incompatibilities, there are critical safety measures to take when preparing and eating crabs.
Discard the Viscera (Internal Organs)
The viscera, also known as the tomalley or "green gland," is the soft, greenish material found in the body cavity of crabs. It is crucial to discard this part as it can accumulate marine toxins, such as domoic acid. High levels of domoic acid can cause paralytic shellfish poisoning, with symptoms ranging from dizziness and headaches to severe neurological problems in extreme cases. The cooking process does not eliminate this toxin, so proper cleaning is essential. The best practice is to always remove the viscera before cooking and rinse the body cavity.
Ensure Proper Cooking
Raw or undercooked crab is a major risk factor for foodborne illnesses. Crabs can harbor pathogens like Vibrio parahaemolyticus and parasites such as lung fluke. The only way to eliminate these microorganisms is by thoroughly cooking the crab at a high temperature. Marinating raw crab does not kill these organisms. Cooking recommendations usually include boiling for 10-15 minutes or steaming for 15-20 minutes, depending on the crab's size, to ensure it reaches a safe internal temperature.
Comparison Table: Best vs. Worst Crab Pairings
| Food Type | Best Pairings (Safe and Delicious) | Worst Pairings (Potentially Problematic) |
|---|---|---|
| Beverages | Water, white wine, lager, ginger ale | High-tannin red wine, tea, alcohol in excess |
| Sauces/Flavors | Melted butter, garlic butter, fresh herbs, Old Bay spice | Creamy dairy-based sauces, heavy sauces |
| Sides | Lightly steamed or grilled vegetables, corn on the cob, coleslaw | Dairy products (milk, cheese, curd), heavy legumes (beans, lentils) |
| Fruits | Not typically paired, but can be consumed separately | Excessive citrus fruits, watermelon, other watery fruits |
| Heavy Foods | No heavy pairings recommended; keep it light | High-starch foods (heavy pasta, potatoes), legumes |
| Other Seafood | Other shellfish, white fish | None, but watch for high-purine effects with excessive intake |
Conclusion: Savor Your Crab Meal Safely
While crab is a delicious and nutritious delicacy, enjoying it safely requires being mindful of what you pair with it. Avoiding common culprits like heavy dairy, high-tannin beverages, and excessive alcohol can help prevent digestive discomfort. Most importantly, prioritizing food safety by always cooking crab thoroughly and discarding the internal viscera is essential to protect against harmful toxins and pathogens. By being aware of these simple guidelines, you can ensure your next crab feast is both delicious and safe.

Frequently Asked Questions
Can you drink milk with crab?
It is generally not recommended to drink milk with or after eating crab, as the combination of high protein can cause digestive issues like bloating and indigestion. For some, it can also lead to skin irritations or allergic reactions.
Why can't you eat tea with crabs?
Tea contains tannic acid, which can react with the calcium in crab meat to form indigestible compounds. This can irritate the digestive system and cause discomfort.
Is it bad to eat crab with citrus fruits like lemon?
While a small amount of citrus like lemon on crab is common, consuming large quantities of high-acid fruits or drinks can cause bloating, indigestion, and discomfort due to the acidity interfering with protein digestion.
What are the dangers of eating raw crab?
Raw crab can contain harmful bacteria and parasites, such as Vibrio parahaemolyticus and lung flukes. Consuming them can lead to severe food poisoning or parasitic infections. Thorough cooking is the only way to eliminate these risks.
Why should you not eat the crab's internal organs (tomalley)?
The viscera, or tomalley, can accumulate harmful marine toxins, such as domoic acid. This toxin is not destroyed by cooking and can cause paralytic shellfish poisoning, leading to neurological symptoms or, in severe cases, death.
Can you drink alcohol with crabs?
Moderate consumption of alcohol, especially light beer or white wine, is typically fine. However, excessive alcohol can promote the conversion of purines in crab into uric acid, potentially triggering gout attacks in susceptible individuals.
