What is the protein content of 100 g of rohu fish?
The protein content in 100 g of rohu fish can vary slightly depending on whether it is raw or cooked. For a standard, cooked fillet, a 100-gram portion provides a substantial 17–20 grams of protein. For fresh, raw rohu, the protein amount is closer to 16 grams per 100g. The higher concentration of protein in cooked fish is due to the loss of water during the cooking process. As water evaporates, the remaining nutrients, including protein, become more concentrated by weight. This makes rohu a powerful source of lean, high-quality protein for individuals seeking to increase their intake without adding excessive fat.
Beyond protein: other key nutrients in rohu
While its protein content is a major highlight, rohu fish is also a nutritional powerhouse, rich in many other essential vitamins and minerals. Here is a look at what else you can find in a typical 100g serving:
- Omega-3 Fatty Acids: Rohu is a good source of omega-3s, specifically EPA and DHA, which are crucial for brain health and reducing inflammation.
- Vitamins: It is loaded with essential vitamins, including vitamin A for vision, vitamin D for bone health, and B-complex vitamins like B12 for nerve function and energy production.
- Minerals: The fish is a valuable source of minerals such as calcium and phosphorus for strong bones and teeth, potassium for blood pressure regulation, and selenium for immune defense.
The health benefits of rohu fish
Consuming rohu fish regularly can offer a wide range of health advantages, primarily driven by its rich protein and Omega-3 content.
- Cardiovascular Health: The Omega-3 fatty acids help lower triglycerides and improve blood flow, which in turn reduces the risk of heart disease, stroke, and myocardial infarction.
- Cognitive Function: Omega-3s are vital for brain development and function, supporting improved memory and regulating mood.
- Bone and Joint Health: High levels of protein, calcium, and phosphorus work together to support strong bones and teeth, making it an excellent dietary choice for all ages and helping to mitigate conditions like osteoporosis.
- Immune Support: Key nutrients like selenium, zinc, and Vitamin A help fortify the immune system, protecting the body against infections.
- Weight Management: As a high-protein, low-fat food, rohu promotes satiety and reduces hunger cravings, which can aid in weight loss or management when prepared healthily.
How rohu compares to other popular fish
| Fish (100g cooked) | Protein Content (g) | Omega-3s | Fat Content (g) | Key Advantage |
|---|---|---|---|---|
| Rohu | 17–20 | Good | 2–3 | Excellent lean protein source with good Omega-3s. |
| Salmon | 22–26 | Very High | 13–20 | Higher protein and much higher Omega-3s, but also higher in fat. |
| Mackerel | 19–21 | High | 10–15 | Higher Omega-3s and protein, but also more fat than rohu. |
| Catla | ~16 | Moderate | ~3 | Similar nutritional profile to rohu, also a lean protein source. |
Cooking methods and nutritional retention
How you prepare your rohu fish significantly impacts its nutritional profile and overall healthiness. To maximize the benefits, consider these methods:
- Grilling: Cooking rohu on a grill with minimal oil preserves its natural flavors and prevents the addition of extra fats, keeping it lean.
- Steaming: Steaming is one of the healthiest ways to cook fish, as it retains most of the vitamins and minerals while keeping the meat moist and tender.
- Baking: Baking with herbs and lemon juice is another excellent option for a low-fat, high-flavor meal. Avoid deep-frying, which adds excess calories and unhealthy fats.
How to incorporate rohu into your diet
Rohu fish is incredibly versatile and can be used in a variety of dishes. From a traditional Bengali fish curry (Rui Kalia) to a simple pan-seared fillet, there are numerous ways to enjoy it. When preparing, focus on fresh ingredients and healthy cooking techniques to get the most out of its nutritional benefits. A simple preparation with a squeeze of lime, some coriander, and mild spices is often all that's needed to create a delicious and healthy meal.
Conclusion
In conclusion, rohu fish provides a very respectable amount of protein, with a 100-gram serving offering 17 to 20 grams of high-quality protein when cooked.
