A 100-gram serving of cooked brown rice typically provides about 2.6–3 grams of protein, plus fiber and slow-digesting carbs.
Brown rice turns up on many plates as a steady, comforting side, yet most people never look closely at how much protein they actually get from a 100 gram spoonful. When you track macros for muscle gain, steady energy, or blood sugar control, knowing the exact brown rice protein per 100 grams helps you build plates that match your goals instead of guessing.
This guide covers cooked and dry brown rice protein per 100 grams, how it compares with other staples, and straightforward ways to turn that mild grain into a more balanced, protein aware meal.
Brown Rice Protein Per 100G In Cooked Portions
The figure most people care about is protein in cooked brown rice, because that is what actually lands in the bowl. Data drawn from an USDA-based nutrient table for cooked long grain brown rice shows that 100 grams of cooked long grain brown rice holds roughly 2.6–2.8 grams of protein and about 120 calories.
Medium grain cooked brown rice sits in almost the same range, with around 2.3–2.7 grams of protein per 100 grams depending on the variety and moisture level. That means the protein density of cooked brown rice is modest: most of the weight comes from water and starch, with just a small slice from protein.
Home cooks often serve more than the reference portion without noticing. A single extra scoop of rice can double the grams of cooked brown rice on the plate, which also doubles the small protein contribution and pushes total calories higher.
Dry Brown Rice Protein Per 100G
When you look at the dry grain in a jar or bag, the picture shifts. In its uncooked form, brown rice is much more concentrated because there is no cooking water yet. An analysis of uncooked long grain brown rice lists around 7.5–8 grams of protein per 100 grams of dry rice, based on a USDA-linked profile for raw long grain brown rice.
Once that dry 100 gram portion absorbs water in the pot or rice cooker, the weight nearly triples. The total protein stays the same, but it spreads out over more cooked grams. That change is why labels on dry rice often show higher protein per 100 grams than the values you see for cooked rice in tracking apps.
When you batch cook brown rice for the week, that dry weight trick gives a shortcut. Weigh the uncooked rice once, write down the total protein for the pot, and then divide it across the number of meals you plan to eat.
Brown Rice Protein Compared With Calories And Carbs
Brown rice is still a grain first and a protein source second. In that same 100 gram cooked portion you pick up around 22–25 grams of carbohydrate along with a small amount of fat and about 1.5–2 grams of fiber. The protein contributes only a small slice of the calories, which matches the picture nutrition researchers describe when they talk about brown rice as a whole grain carbohydrate base rather than a main protein anchor.
Whole grain guidance from university public health teams notes that brown rice helps heart health, better cholesterol patterns, and improved blood sugar response across many studies, largely thanks to its bran layer, fiber, and phytochemicals rather than very high protein content. The whole grains summary from Harvard T.H. Chan School of Public Health states that swapping refined grains for whole grains such as brown rice links with lower risk of cardiovascular disease and type 2 diabetes.
| Food (Per 100G) | Protein (G) | Calories (Kcal) |
|---|---|---|
| Brown Rice, Long Grain, Cooked | 2.6–2.8 | 120 |
| Brown Rice, Medium Grain, Cooked | 2.3–2.7 | 112 |
| Brown Rice, Long Grain, Dry | 7.5–8.0 | 360 |
| White Rice, Long Grain, Cooked | 2.0–2.4 | 130 |
| Quinoa, Cooked | 4.0–4.5 | 120 |
| Lentils, Boiled | 8.5–9.0 | 115 |
| Firm Tofu | 14–15 | 140 |
How Brown Rice Protein Per 100G Fits Daily Targets
Most adults land somewhere between 1.2 and 2.0 grams of protein per kilogram of body weight per day when they follow strength training plans or try to keep muscle while leaning out. That range turns into 70–120 grams or more across the day for many active people, so a single 100 gram serving of cooked brown rice covers only a small portion of that target.
A more realistic everyday portion of brown rice, such as 150–200 grams cooked, can deliver about 4–6 grams of protein. If you eat brown rice twice in the same day, perhaps at lunch and dinner, that might bring 8–10 grams of protein from rice alone. The rest still needs to come from higher protein foods such as poultry, fish, eggs, dairy, soy, or legumes.
Someone on a higher protein intake might treat brown rice as a background contributor, while someone closer to the lower end of the range can still let these few grams per serving help close the gap after protein rich foods have already been added.
Brown Rice Protein In Real 100 Gram Serving Sizes
Labels and charts talk about protein per 100 grams, yet very few people weigh out exactly that amount for every meal. To make those numbers easier to apply, it helps to map them to familiar kitchen portions such as cups and spoonfuls.
A level cup of cooked brown rice weighs close to 185–200 grams for most long grain varieties. Using the same density figures, that single cup can contain around 5–6 grams of protein. A small half cup serving closer to 90–100 grams cooked gives around 2.5–3 grams of protein, which matches the original 100 gram reference quite closely.
| Serving | Approximate Weight (G) | Protein (G) |
|---|---|---|
| Half Cup Cooked Brown Rice | 95–105 | 2.5–3.0 |
| One Cup Cooked Brown Rice | 185–200 | 5.0–6.0 |
| Small Side Serving At A Restaurant | 120–150 | 3.0–4.0 |
| Large Bowl Serving At Home | 200–250 | 6.0–7.5 |
| Dry Brown Rice Before Cooking | 50 | 3.7–4.0 |
| Dry Brown Rice For Two Cooked Portions | 100 | 7.5–8.0 |
| Ready Pouch Single Serving Brown Rice | 120–125 | 3.0–3.5 |
Turning Brown Rice Into A Higher Protein Meal
Since brown rice on its own does not carry much protein per 100 grams, the real power sits in what you plate around it. Pairing brown rice with beans or lentils quickly lifts the total protein and improves the amino acid profile at the same time. A bowl with 100 grams of cooked brown rice and 100 grams of cooked lentils can reach 11–12 grams of protein while still feeling light and easy to digest.
Combining brown rice with tofu, tempeh, eggs, or grilled chicken takes the total even higher. A stir fry built from 150 grams of cooked brown rice plus 120 grams of diced firm tofu can push past 20 grams of protein with a pleasant mix of textures. The rice brings chew and fiber, while the tofu or chicken brings dense protein that boosts satiety.
Seasoning choices matter too. Sauces built from nut butter, yogurt, tahini, or soy sauce with minced tofu can boost both flavor and protein, while toppings such as chopped nuts or seeds add a subtle extra lift without changing the texture of the rice itself.
Health Benefits That Sit Beside Brown Rice Protein
Protein per 100 grams is only one slice of the picture. Brown rice keeps its bran and germ, which means it carries more fiber, magnesium, and other minerals than white rice. Reviews of whole grain research show that higher whole grain intake links with lower risk of heart disease, stroke, and type 2 diabetes over time, and brown rice appears in many of those studies as one of the staple grains people eat regularly.
An umbrella review of whole grain studies reported that habits built around whole grains such as brown rice, oats, and whole wheat help lower total cholesterol levels and healthier body weight patterns over the years. These findings match guidance from large health organizations that encourage people to shift a portion of their daily grain intake toward brown rice and other intact grains.
General nutrition resources for consumers also describe brown rice as a helpful base for balanced meals. The brown rice nutrition summary from Verywell Fit notes that a cup of cooked brown rice delivers several grams of protein, a meaningful amount of fiber, and a range of B vitamins that help normal energy metabolism.
Who Gets The Most Value From Brown Rice Protein Data
Knowing the exact brown rice protein per 100 grams helps anyone who relies on rice as a daily staple. People who follow plant forward diets and eat brown rice several times a day can use these numbers to check whether their total protein intake still lands in a healthy range, especially if they are also training with weights or running long distances.
A clear picture of brown rice protein per 100 grams removes guesswork from one of the most common carbohydrate foods on the table. With that data in hand, you can keep brown rice in your routine while steering your macros where you want them to go.
