The Core Nutrient Facts: Protein in Raw Tilapia
For a standard 100g serving, raw tilapia provides approximately 20-23 grams of protein. This makes it a significant source of this essential macronutrient. As a lean fish, it is also low in fat and calories, offering a calorie-efficient way to boost protein intake without adding excessive saturated fats. Nutritional databases commonly report figures within this range, such as 20.08g or 20.43g of protein per 100g.
Why the Variation in Reported Protein Levels?
Slight differences in reported protein content can occur due to several factors. These include the fish's diet and whether it is farmed or wild-caught, as different environments and feeds can influence nutritional composition. The season and the fish's maturity can also play a role, as these affect fat and moisture content, which in turn can impact protein concentration. Additionally, variations can arise from the specific laboratory testing methods and the nutritional databases used for reporting.
Raw vs. Cooked: How Protein Content Changes
The protein content differs between raw and cooked tilapia. Cooking causes moisture loss, which concentrates the remaining nutrients. Consequently, a 100g serving of cooked tilapia will have a higher protein density than the same weight of raw fish. While 100g of raw tilapia contains about 20-23g of protein, a 100g portion of dry-heat cooked tilapia can contain approximately 26g of protein. This increase in protein per gram is due to the reduction in water, not the creation of new protein.
A Quick Comparison Table: Raw vs. Cooked Tilapia (per 100g)

The Broader Nutritional Picture of Tilapia
Beyond its high protein, tilapia offers other nutritional benefits. It is a source of several essential vitamins and minerals. These include Vitamin B12, important for the nervous system and red blood cells, and Selenium, an antioxidant supporting thyroid function. It also provides Phosphorus for bones and energy metabolism, Potassium for fluid balance, and Vitamin D for calcium absorption and immune health.
Health Benefits of Incorporating Tilapia into Your Diet
Adding tilapia to your diet can provide several health advantages. As a complete protein, it supports muscle repair and growth, beneficial for active individuals. Its high protein content contributes to satiety, aiding in weight management. While lower in omega-3s than fatty fish, tilapia still offers some benefits for brain and heart health.
Factors for Consideration When Purchasing Tilapia
When buying tilapia, consider its source. Some farming practices have raised concerns regarding environmental impact and antibiotic use. To make a healthy and responsible choice, look for tilapia from regions with strict regulations or choose wild-caught options. Resources like the Monterey Bay Aquarium's Seafood Watch program (www.seafoodwatch.org) can provide guidance on sustainable seafood.
Conclusion
In conclusion, 100g of raw tilapia fish is a lean source of high-quality protein, offering approximately 20-23 grams. This fish is low in calories and fat and provides essential vitamins and minerals supporting muscle health, weight management, and overall well-being. Remember that cooking concentrates nutrients, increasing protein per gram in cooked tilapia compared to raw. Choosing responsibly sourced tilapia ensures you benefit from this nutritious and versatile ingredient in a balanced diet.
