How Much Protein in Prawns

Prawns are one of the UK’s favourite seafood choices, appreciated for their delicate flavour, versatility, and impressive nutritional value. They feature in everything from classic prawn cocktails and stir-fries to curries and pasta dishes. While many people know that prawns are low in fat and calories, fewer realise how rich they are in protein. Understanding how much protein is in prawns and how they contribute to health can help you make more informed and balanced meal choices.

The Protein Content in Prawns

Prawns are exceptionally high in protein relative to their calorie content. On average, 100 grams of cooked prawns provide around 24 grams of protein, while raw prawns contain roughly 20 grams per 100 grams. This means a standard serving of prawns, around 75 grams, delivers about 18 grams of protein. Because they are so protein-dense yet low in fat, prawns are one of the leanest animal protein sources available.

Their high protein content makes them ideal for supporting muscle repair, energy, and satiety without adding unnecessary calories. Prawns are also quick to cook and easy to digest, making them a convenient and efficient way to meet your daily protein needs.

Comparing Prawns to Other Protein Sources

When compared to other common protein sources, prawns perform exceptionally well. Chicken breast provides around 30 grams of protein per 100 grams, while salmon offers about 25 grams. Prawns, at 24 grams, are very similar to these high-quality proteins but with significantly less fat and fewer calories.

For example, 100 grams of cooked prawns provide only about 100 calories and less than 1 gram of fat, compared to roughly 165 calories and 3.5 grams of fat in the same amount of chicken breast. This makes prawns an excellent option for those looking to increase protein intake while managing calorie consumption.

Prawns also provide a complete protein source, containing all nine essential amino acids in ideal proportions for supporting muscle growth, tissue repair, and overall body maintenance.

The Role of Protein in Prawns

Protein is the primary nutrient in prawns, making up around 80 percent of their dry weight. This protein supports muscle growth, repair, and enzyme production, while also playing an important role in maintaining healthy hair, skin, and nails. The amino acid profile of prawns is comparable to that of other lean meats, meaning they are a high-quality source of easily absorbed protein.

Because prawns are low in fat and carbohydrates, they are particularly beneficial for those on calorie-controlled or high-protein diets. Including them in meals can help increase total protein intake without significantly affecting overall calorie balance.

The Nutritional Value of Prawns

Beyond protein, prawns are rich in essential nutrients that support overall health. A 100-gram portion of cooked prawns provides roughly 100 calories, 24 grams of protein, less than 1 gram of fat, and virtually no carbohydrates. They are an excellent source of vitamins and minerals such as vitamin B12, iodine, selenium, and zinc, all of which play vital roles in energy production, metabolism, and immune function.

Prawns also contain omega-3 fatty acids, which contribute to heart and brain health. Although the levels are lower than those found in oily fish such as salmon or mackerel, prawns still provide a useful boost of these beneficial fats.

Prawns and Muscle Health

The high protein content of prawns makes them an excellent food for maintaining and building muscle. Protein supports the repair of muscle fibres following exercise, helping to rebuild tissue and improve strength. For athletes or individuals engaging in regular physical activity, prawns provide a lean and efficient source of protein that aids recovery without adding excess calories or fat.

Including prawns in meals following workouts helps supply the body with the amino acids necessary for repair and growth. Combined with a source of carbohydrates, such as rice or pasta, they can help replenish energy stores and optimise recovery.

Prawns and Heart Health

Prawns are often praised for their heart-friendly nutritional profile. Despite their cholesterol content, research shows that eating prawns does not significantly raise blood cholesterol in most people. This is because they are low in saturated fat and contain heart-healthy omega-3 fatty acids, which help reduce inflammation and support normal heart rhythm.

The potassium, magnesium, and selenium in prawns also contribute to cardiovascular health by supporting healthy blood pressure and protecting against oxidative stress. When prepared healthily, such as grilled, steamed, or lightly sautéed, prawns can form part of a balanced diet that supports heart wellbeing.

Prawns and Energy

Although prawns are low in carbohydrates, their protein content makes them a strong source of sustained energy. Protein takes longer to digest than carbohydrates, helping to keep you fuller for longer and maintain stable blood sugar levels. This slow, steady energy release makes prawns ideal for inclusion in balanced meals that support concentration, stamina, and productivity throughout the day.

Pairing prawns with complex carbohydrates such as wholegrain rice, quinoa, or pasta provides a well-rounded meal that fuels both immediate energy and long-term recovery.

Prawns and Weight Management

Prawns can support healthy weight management due to their high protein and low-calorie content. Protein promotes satiety, helping you feel full after eating and reducing the temptation to snack between meals. Because prawns provide a substantial amount of protein with very little fat, they are an excellent choice for those seeking to manage body weight while maintaining muscle mass.

Replacing higher-calorie meats with prawns in recipes such as stir-fries, curries, or salads can significantly reduce calorie intake without sacrificing flavour or satisfaction. Their mild taste makes them adaptable to a wide variety of cuisines, making it easy to enjoy them regularly as part of a balanced meal plan.

Prawns and Brain Health

Prawns contain nutrients that support brain function and cognitive performance. Vitamin B12 is essential for nerve function and helps produce red blood cells, while iodine supports healthy thyroid activity, which influences metabolism and brain development. The small but beneficial amount of omega-3 fatty acids in prawns further supports brain health and may help maintain focus and memory.

Including prawns in the diet regularly can therefore contribute to both short-term alertness and long-term cognitive health.

Prawns and Immune Function

The zinc, selenium, and vitamin B12 in prawns help support the immune system and protect cells from oxidative damage. Selenium, in particular, acts as an antioxidant that helps neutralise free radicals and reduce inflammation. This supports the body’s ability to fight infection and recover from illness more efficiently.

Because prawns are rich in protein, they also help maintain healthy tissues and produce enzymes that play a role in immune defence.

Prawns and Skin Health

Prawns can contribute to healthy skin thanks to their nutrient profile. The protein they contain provides the amino acids needed for collagen production, which helps maintain skin elasticity and strength. The antioxidants selenium and zinc protect skin cells from oxidative stress, while vitamin B12 supports cell renewal.

Regularly including prawns in a balanced diet can therefore help maintain a glowing, youthful complexion and support the skin’s natural repair processes.

How Much Protein Do You Need Each Day?

According to UK dietary guidelines, adults should aim for about 0.75 grams of protein per kilogram of body weight each day. For someone weighing 70 kilograms, that equates to roughly 52 grams of protein daily. A 100-gram serving of prawns provides almost half that amount, making them one of the most protein-efficient foods available.

Including prawns in a few meals per week can make it easier to meet daily protein requirements while enjoying a delicious and nutritious source of lean protein.

How to Include Prawns in a Balanced Diet

Prawns can be prepared in many different ways and easily incorporated into a balanced UK diet. They can be grilled, boiled, steamed, or stir-fried and pair beautifully with vegetables, grains, or pasta. For a high-protein meal, try adding prawns to salads, wraps, or stir-fries with brown rice or quinoa.

When cooking prawns, it is best to avoid heavy sauces or frying, as these can add unnecessary fat and calories. Instead, opt for fresh herbs, garlic, lemon, or olive oil for natural flavour and health benefits.

Conclusion

Prawns contain around 24 grams of protein per 100 grams cooked, making them one of the leanest and most efficient sources of high-quality protein available. They are rich in essential nutrients such as vitamin B12, selenium, iodine, and zinc, all of which support heart health, immunity, and energy metabolism.

Their versatility, quick cooking time, and light taste make prawns an easy way to enjoy a nutritious meal that supports muscle growth and overall wellbeing. Whether added to salads, curries, or pasta dishes, they are a satisfying and healthy addition to any diet.
