DHA, a type of omega-3 found abundantly in crab, is crucial for brain development in infants and maintenance of cognitive function throughout life (Hei, 2023).

3. Bone Strength Improvement

Crabs are an excellent source of phosphorus and calcium, two minerals essential for bone health. A 100-gram serving of crab meat provides about 60% of the daily recommended intake of phosphorus (Nutrition Data, 2024). A long-term study involving 5,000 participants found that those with higher seafood intake, including crab, had a 22% lower risk of osteoporosis (Zalloua et al., 2007).

4. Immune System Boost

The high zinc content in crab meat plays a crucial role in immune function. Zinc is involved in the development and function of immune cells, and a deficiency can lead to a weakened immune response (Shankar & Prasad, 1998). A study in the Journal of Nutrition found that individuals with adequate zinc intake from sources like crab had 30% fewer respiratory infections compared to those with low zinc intake (Roohani et al., 2013).

5. Anemia Prevention

Crab meat is rich in iron, a mineral essential for preventing anemia. A 3-ounce serving of crab provides about 15% of the daily recommended intake of iron (USDA, 2019). Research has shown that incorporating iron-rich seafood like crab into the diet can increase hemoglobin levels by up to 0.5 g/dL in anemic individuals within three months (Callister et al., 2020).

6. Weight Management Support

Despite being low in calories, crab meat is high in protein, making it an excellent food for weight management. A 100-gram serving of crab meat contains only about 100 calories but provides 20 grams of protein (Nutrition Data, 2024). A study in the International Journal of Obesity found that participants following a high-protein diet including seafood like crab lost 25% more weight over 12 weeks compared to those on a standard protein diet (Moon & Koh, 2020).

7. Thyroid Function Regulation

Crabs are a good source of selenium, a mineral crucial for thyroid function. One serving of crab can provide up to 60% of the daily recommended intake of selenium (USDA, 2019). Research has shown that adequate selenium intake is associated with a 50% reduced risk of thyroid dysfunction (Wang et al., 2023).

8. Skin Health Promotion

The omega-3 fatty acids and zinc found in crabs contribute to skin health. These nutrients help maintain skin elasticity and protect against UV damage (Michalak et al., 2021). A study in the Journal of Dermatology found that individuals with higher seafood intake had 25% fewer signs of skin aging compared to those with low seafood consumption (Cao et al., 2020).

9. Mood Regulation

The high levels of vitamin B12 and omega-3s in crab may play a role in mood regulation. Deficiencies in these nutrients have been linked to an increased risk of depression (Grosso et al., 2014). A large-scale study involving 10,000 participants found that those consuming seafood like crab regularly had a 20% lower risk of developing depression over a 5-year period (Sanchez-Villegas et al., 2018).

10. Cancer Risk Reduction

Some compounds found in crab, such as selenium and omega-3 fatty acids, have shown potential in reducing cancer risk. A meta-analysis of 20 studies found that higher seafood intake was associated with a 15% lower risk of colorectal cancer (Caini et al., 2022). The antioxidant properties of these nutrients may help protect cells from damage that can lead to cancer (Didier et al., 2023).

11. Diabetes Management

The protein and omega-3 fatty acids in crab can be beneficial for diabetes management. These nutrients help stabilize blood sugar levels and improve insulin sensitivity (Sinha et al., 2023). A study in the Journal of Diabetes Care found that individuals who included seafood like crab in their diet three times a week had a 22% lower risk of developing type 2 diabetes compared to those who rarely ate seafood (Patel et al., 2009).

Crab Nutrition Facts

Crabs offer numerous health benefits, which can be better understood by examining their impressive nutritional profile. Let’s dive into the details:

Crab nutrition table

Before we break down each nutrient, here’s a comprehensive overview of crab nutrition:

How many calories are in crabs?

Crabs are a low-calorie seafood option. A 100-gram serving of crab meat contains just 87 calories, which is about 4% of the daily recommended intake (DRI) for a 2,000-calorie diet. A typical serving size of 3 ounces (85 grams) provides approximately 97 calories or 5% of the DRI.

To burn off these calories, you’d need about 10 minutes of vigorous swimming or 15 minutes of jogging. This makes crab an excellent choice for those managing their weight or looking for a protein-rich, low-calorie food option.

How much protein is in crabs?

Crabs are an excellent source of high-quality protein. A 100-gram serving of crab meat packs an impressive 18.5 grams of protein, meeting 37% of the DRI. A typical 3-ounce serving provides about 20.6 grams of protein, which is 41% of the DRI.

This high protein content makes crab an ideal food for muscle building, repair, and maintenance. It’s particularly beneficial for athletes, older adults, and those recovering from injuries.

How many carbs are in crabs?

Crabs are virtually carb-free, containing 0 grams of carbohydrates per 100 grams or per serving. This makes them an excellent choice for low-carb and ketogenic diets. The absence of carbs also means that crab meat doesn’t cause blood sugar spikes, making it suitable for people with diabetes or those managing their blood glucose levels.

How much fat is in crabs?

Crabs are very low in fat. A 100-gram serving contains only 1.2 grams of total fat, which is 2% of the DRI. A typical 3-ounce serving has 1.3 grams of fat, also 2% of the DRI. Here’s a breakdown of the fat content:

The majority of fats in crab are healthy unsaturated fats, including omega-3 fatty acids, which are beneficial for heart and brain health.

Are crabs high in cholesterol?

While crabs do contain cholesterol, the amount is moderate. A 100-gram serving of crab meat contains 48 mg of cholesterol, which is 16% of the DRI. A typical 3-ounce serving has 53 mg, or 18% of the DRI.

It’s worth noting that dietary cholesterol doesn’t significantly impact blood cholesterol levels for most people. The American Heart Association suggests that the overall dietary pattern is more important than specific cholesterol intake from individual foods.

Minerals in crabs

Crabs are rich in several essential minerals:

Selenium in crabs supports thyroid function and acts as a powerful antioxidant. Zinc is crucial for immune function and wound healing. Copper aids in iron absorption and the formation of red blood cells. Phosphorus is essential for bone health and energy production.

Vitamins in crabs

Crabs are also a good source of various vitamins:

The standout nutrient is vitamin B12, with a single serving providing over 400% of the DRI. This vitamin is crucial for nerve function and the formation of red blood cells. The other vitamins contribute to various bodily functions, including immune support and antioxidant protection.

Crabs Risks and Side Effects

While crabs offer numerous health benefits, they can pose risks for certain individuals. Shellfish allergies, including crab allergies, are one of the most common food allergies, affecting about 2% of adults. Symptoms can range from mild (hives, itching) to severe (anaphylaxis). If you suspect a crab allergy, it’s crucial to consult an allergist for proper diagnosis and management.

Crabs can also be a source of foodborne illness if not properly handled or cooked. Vibrio bacteria, naturally present in coastal waters, can contaminate crabs and cause illness if consumed raw or undercooked. To mitigate this risk, always cook crabs thoroughly and practice good food safety habits.

Some crabs may contain environmental contaminants like mercury or polychlorinated biphenyls (PCBs). While levels are generally low, pregnant women and young children should limit their intake of certain crab species. The FDA provides guidelines on safe seafood consumption for these groups.

Debunking myths about crabs

Myth: Crabs are high in fat and should be avoided in weight loss diets.
Fact: Crabs are very low in fat, with only 1.2 grams per 100-gram serving. They’re an excellent lean protein source, making them suitable for weight management diets.

Myth: The cholesterol in crabs will raise your blood cholesterol levels.
Fact: While crabs do contain cholesterol, dietary cholesterol has minimal impact on blood cholesterol for most people. The overall diet quality is more important than individual high-cholesterol foods.

Myth: All crabs are high in sodium and bad for heart health.
Fact: Fresh crab meat is naturally low in sodium. High sodium content is usually due to added salt in processing or cooking. When prepared without added salt, crabs can be part of a heart-healthy diet.

Crabs Substitutes

Here’s a comparison of crab substitutes based on key nutrients:

Surimi, often used in imitation crab, is made from processed fish. It’s lower in protein than real crab but still provides omega-3s and some B12. Surimi is more affordable and widely available. However, it often contains additives and may be higher in sodium.

Tofu is a plant-based option that’s high in protein and low in fat. It’s versatile and can mimic crab texture when prepared correctly. Tofu is rich in isoflavones, which may have health benefits. However, it lacks the omega-3s and B12 found in crabs.

Jackfruit has a flaky texture that can resemble crab meat when seasoned. It’s low in calories and high in fiber. Jackfruit is great for vegan diets but is much lower in protein compared to crab. It doesn’t provide the same nutritional profile, especially in terms of protein and minerals.

Mushrooms, particularly oyster or king oyster mushrooms, can mimic the texture of crab meat. They’re low in calories and provide unique compounds like beta-glucans. Mushrooms offer some B vitamins and selenium but are much lower in protein than crab. They’re a good option for adding umami flavor to dishes.

Popular Crab Diets

How to add crabs safely into your diet? Choosing the right diet is important to ensure that you are meeting your nutritional needs while also enjoying the foods you eat. Here are a few of the available crabs-friendly diet options:

1. Mediterranean Diet
2. Pescatarian Diet
3. Low-Carb Diet
4. Paleo Diet
5. Keto Diet
6. Seafood-Focused Diet

The Mediterranean Diet incorporates crab as part of its diverse seafood options. This diet emphasizes plant-based foods, healthy fats, and moderate seafood consumption. It’s known for its heart health benefits and potential to increase longevity. However, some may find it challenging to adapt to if they’re used to a Western diet.

In a Pescatarian Diet, crab plays a significant role alongside other seafood. This diet excludes land animals but includes fish, shellfish, and plant-based foods. It offers flexibility and is rich in omega-3 fatty acids. The main drawback is the need to monitor mercury intake from certain seafood sources.

Low-Carb Diets often feature crab as a protein-rich, zero-carb food option. These diets focus on reducing carbohydrate intake while increasing protein and fat consumption. They can be effective for weight loss and blood sugar control but may lack certain nutrients if not well-planned.

The Paleo Diet includes crab as part of its emphasis on foods available to our prehistoric ancestors. It focuses on whole foods, including lean meats, fish, fruits, and vegetables. While it can be anti-inflammatory, it restricts grains and legumes, which some nutritionists consider beneficial.

In a Keto Diet, crab is valued for its high protein and low carb content. This diet aims to induce ketosis through very low carb intake and high fat consumption. It can lead to rapid weight loss and improved mental clarity for some, but it’s often difficult to sustain long-term.

A Seafood-Focused Diet, while not a formal diet plan, centers around high consumption of various seafood, including crab. This approach ensures a high intake of omega-3 fatty acids and diverse nutrients. However, it can be expensive and may lack variety for some people.

How to Cook Crabs?

Boiled crabs are a classic preparation method. To boil crabs, bring a large pot of salted water to a boil, add the crabs, and cook for about 15 minutes until they turn bright red. This method is simple and helps retain the crab’s natural flavors. Boiling preserves most of the crab’s nutrients, making it one of the healthiest cooking methods.

For a healthier alternative to deep-frying, try air fryer crabs. Brush the crab with a little oil and air fry at 375°F (190°C) for about 8-10 minutes. This method results in a crispy exterior while keeping the meat tender. Air frying requires minimal added fat, making it a lower-calorie option. However, it may not be suitable for whole crabs due to size limitations.

Grilled crabs offer a smoky flavor that many enjoy. Brush the crab with oil and grill over medium-high heat for 4-5 minutes per side. Grilling can help reduce the fat content as some of it drips away during cooking. This method retains most nutrients and adds a unique flavor profile.

For a hands-off approach, try baked crabs. Preheat your oven to 375°F (190°C), place the crab in a baking dish with a bit of water or broth, and bake for about 25 minutes. Baking is a gentle cooking method that helps retain moisture and nutrients. It’s particularly good for crab dishes with stuffing or toppings.

Steamed crabs are another healthy option. Place a steamer basket in a large pot with a few inches of boiling water, add the crabs, and steam for about 10-12 minutes. Steaming helps preserve the crab’s natural flavors and nutrients better than boiling, as the crab doesn’t come into direct contact with the water.

While raw crab is consumed in some cuisines, it’s generally not recommended due to the risk of foodborne illness. Always ensure crab is thoroughly cooked to an internal temperature of 145°F (63°C) to eliminate harmful bacteria.

Always follow proper storage guidelines to ensure the safety and quality of your crab.

How to keep crabs fresh?

To keep crabs fresh, proper storage is key. For live crabs, store them in an open container lined with damp newspaper or seaweed in the refrigerator at 40°F (4°C) or below. Cover the container with a damp cloth and ensure the crabs can breathe; never store live crabs in water or airtight containers. For cooked crab meat, store it in airtight containers or wrap tightly in plastic wrap or aluminum foil before refrigerating. Studies show that reducing oxygen exposure can extend seafood shelf life by up to 50%. If you’re not planning to consume the crab within a few days, freezing is the best option for long-term storage. Always handle crabs with clean hands and utensils to prevent bacterial contamination.
