The exact amount of protein in 100 grams of cooked black rice is a topic with slight variations depending on the source. Official nutritional databases and expert analyses place the value around 2.7 to 2.9 grams per 100g serving. This may seem modest when compared to uncooked values, which can be significantly higher, but it represents a solid contribution to a plant-based diet. It is important to distinguish between uncooked and cooked nutritional information, as cooking involves water absorption that adds weight and dilutes nutrient concentration. For instance, while 100 grams of uncooked black rice may contain around 9 grams of protein, that same rice, once cooked, expands to a larger volume and weight, meaning the protein per 100-gram measure is lower.
Nutritional Profile of Cooked Black Rice
Beyond its notable protein content, black rice is a superfood packed with essential vitamins and minerals. The deep black-purple color is attributed to a high concentration of anthocyanins, powerful antioxidants also found in blueberries. Its bran and germ remain intact, which is why it offers more fiber and nutrients than refined white rice. A typical 100-gram serving of cooked black rice also provides:
- Carbohydrates: Approximately 28-38 grams, depending on the source.
- Fiber: Around 1-3 grams, promoting digestive health.
- Iron: A good source of this mineral essential for oxygen transport in the blood.
- Antioxidants: High levels of anthocyanins, lutein, and zeaxanthin, which support cellular health and vision.
Black Rice Protein: What to Know
For those on a plant-based diet, the quality of protein is just as important as the quantity. Black rice is often considered a source of complete protein because it contains all nine essential amino acids. While the amino acid ratios may not be as optimal as animal sources, combining it with other plant foods, such as beans or lentils, easily rounds out the profile. The protein in black rice is also highly digestible, allowing the body to absorb and utilize its nutrients efficiently.
Comparison of Rice Varieties
To put black rice's protein content into context, it is helpful to compare it with other common rice varieties. This table shows the approximate nutritional values per 100 grams of cooked rice, highlighting the differences in protein, fiber, and antioxidant properties.
| Feature | Cooked Black Rice | Cooked Brown Rice | Cooked White Rice | 
|---|---|---|---|
| Protein (per 100g) | ~2.9 g | ~2.6 g | ~2.7 g | 
| Fiber (per 100g) | ~1-3 g | ~1.8 g | ~0.4 g | 
| Antioxidant Content | Very High (Anthocyanins) | Moderate | Low | 
| Whole Grain | Yes | Yes | No (Refined) | 
| Glycemic Index | Low | Low-Medium | High | 
Tips for Boosting Protein with Black Rice Meals
To maximize the protein benefits of black rice, consider these simple preparation methods:
- Pair with Legumes: Cook black rice with black beans, chickpeas, or lentils to create a more complete and substantial protein source. A classic black beans and rice dish is enhanced with the nutty flavor and texture of black rice.
- Add Nuts and Seeds: Top your black rice bowl or salad with toasted pecans, almonds, or hemp hearts. These additions increase the protein and healthy fat content.
- Mix in Vegetables: Stir-fry cooked black rice with high-protein vegetables like edamame and mushrooms.
- Use Protein-Rich Liquids: Instead of water, cook your rice in beef or vegetable bone broth to infuse it with additional protein and flavor.
- Create a Power Bowl: Combine black rice with eggs, tofu, or grilled chicken for a balanced and protein-heavy meal.
Conclusion
While the raw protein content might seem higher, a standard 100-gram serving of cooked black rice provides a respectable 2.7 to 2.9 grams of quality plant-based protein. Its value extends far beyond just protein, offering high levels of antioxidants, fiber, and essential minerals, making it a superior choice to white rice. By combining it with other protein sources like legumes, nuts, or seeds, you can easily create delicious and nutrient-packed meals. Black rice's nutty flavor and chewy texture also make it a versatile and healthy addition to a variety of dishes, from stir-fries to salads.

The protein content may be a small piece of the puzzle, but black rice's overall nutritional superiority and its ability to act as a complete protein with the right pairings make it a true asset to a healthy diet.
Frequently Asked Questions
Is the protein in black rice a complete protein?
Yes, black rice is considered a complete protein because it contains all nine essential amino acids, which are crucial for muscle synthesis and other bodily functions.
Does black rice have more protein than brown rice?
Per 100 grams, uncooked black rice has more protein than uncooked brown rice. However, cooked values are very similar, with some sources showing slightly more protein in cooked brown rice due to variations in cooking methods and water absorption.
How can I increase the protein in a black rice dish?
To increase the protein in a black rice dish, you can add legumes like black beans, lentils, or edamame. Toppings such as nuts, seeds (hemp, sesame), or tofu also effectively boost the protein content.
What is the best way to cook black rice to preserve its protein?
The protein in black rice is stable during cooking. To best preserve all nutrients, cook it with the recommended water ratio to avoid over-dilution. Soaking the rice beforehand can also help achieve a better texture.
Is black rice protein easily absorbed by the body?
Yes, black rice protein is easily digestible and absorbable. As a whole food source, it also contains fiber and other nutrients that support overall digestion and nutrient uptake.
Can black rice help with weight loss due to its protein content?
The protein and high fiber content in black rice can aid weight loss by promoting feelings of fullness and reducing appetite. Pairing it with a calorie-restricted diet may lead to more significant results.
Does soaking black rice affect its protein content?
No, soaking black rice primarily affects its texture and cooking time by softening the outer bran layer, but it does not significantly change the protein content or nutritional value.
Conclusion
While the exact amount of protein in 100 grams of cooked black rice hovers between 2.7 and 2.9 grams, it is a nutritionally superior grain packed with antioxidants, fiber, and a complete amino acid profile. By creatively combining it with other plant-based protein sources, you can easily turn a simple bowl of black rice into a powerful, satisfying, and healthy meal.
