When it comes to lean, high-quality protein, grouper is a top contender in the seafood world. The exact protein content in 4 oz of grouper depends on whether it is raw or cooked. A 4-ounce (114 gram) serving of raw grouper contains roughly 23 grams of protein. However, cooking the fish—for example, with dry heat—causes it to lose moisture, concentrating the protein and other nutrients into a smaller overall weight. This means a 4-ounce serving of cooked grouper can pack an even higher protein punch, reaching around 28.1 grams. This distinction is important for those meticulously tracking their macronutrient intake.
The Nutritional Profile of a 4 oz Grouper Serving
Beyond its impressive protein content, a standard 4 oz serving of grouper offers a wealth of other health benefits. It is notably low in calories and fat, containing approximately 110 calories and just 2 grams of total fat in its raw state. The fat it does contain is primarily unsaturated and beneficial to health. Grouper is also a source of important vitamins and minerals essential for bodily functions.
Here’s a breakdown of the nutritional highlights in a 4 oz serving:
- Low in Fat: A lean protein source with minimal fat, a great choice for weight management.
- Rich in Selenium: An important mineral for antioxidant defense, protecting cells from damage.
- Packed with B Vitamins: A good source of B6 and B12, crucial for metabolism and nerve function.

Grouper Protein vs. Other Popular Fish
To appreciate grouper's nutritional value, it's helpful to compare it to other commonly consumed fish. While many types of fish are excellent sources of protein, their fat and calorie profiles can differ significantly. This makes grouper a standout choice for those prioritizing lean protein with fewer calories.
