Cooked brown rice gives you steady carbs, a little protein, light fat, and some fiber in a 100-gram serving.
Brown rice is easy to love and hard to measure. One scoop is fluffy. The next scoop is packed tight. A cup can mean different things in different kitchens.
That’s why “per 100 g” is so useful. It’s a clean baseline you can scale for any bowl, any meal, and any tracking app. Below, you’ll get the nutrition per 100 grams of cooked brown rice, plus the real-life details that keep the numbers honest.
What A 100-Gram Portion Means On Your Plate
One hundred grams is a weight, not a volume. With cooked rice, weight is the most reliable way to portion because cooking changes how much water the grain holds.
In many home kitchens, 100 g of cooked brown rice looks like a small bowlful or a loose, heaping half-cup. If your rice is drier and firmer, the same half-cup can weigh more. If it’s softer and wetter, it can weigh less.
If you can, use a scale. Put your bowl on the scale, tap tare, then add rice until you hit your target grams. It’s fast, repeatable, and it removes guesswork.
Cooked Brown Rice Nutrition Per 100G With Label-Style Macros
A common USDA FoodData Central entry for cooked long-grain brown rice lists a plain 100 g serving at 123 calories, with 25.6 g total carbs, 2.7 g protein, and 1.0 g total fat. Fiber comes in at 1.6 g. USDA FoodData Central nutrient profile for cooked long-grain brown rice is the reference used for the tables below.
What Those Macros Tell You
Carbs drive the meal. Brown rice is a starch food. Treat it as your carb base.
Protein is modest. Rice supports a meal, yet it won’t carry your protein target on its own.
Fat stays low. Most fat in a rice bowl comes from oils, sauces, nuts, seeds, or meat you add.
Fiber: Small Number, Real Impact
Fiber in cooked rice looks modest per 100 g. That’s normal. Cooked rice is heavy in water, so the fiber per gram is diluted. If you want a higher-fiber bowl, pair rice with beans, lentils, vegetables, chia, or ground flax.
A simple plate trick: keep rice at 100–150 g, add a palm-size protein, then pile on vegetables. The bowl feels bigger while the calorie swing stays controlled.
Minerals And Vitamins You Get From Brown Rice
Brown rice keeps the bran and germ, so it tends to carry more minerals than white rice that has been milled down to the starchy center. You’ll often see magnesium, manganese, phosphorus, and potassium show up as the standouts.
You won’t “feel” a mineral in one serving, yet the pattern matters across weeks of eating. Whole grains are one of the steady ways people build micronutrients into everyday meals.
Low Sodium Until You Season It
Plain cooked brown rice is naturally low in sodium. When rice tastes salty, it’s usually broth, bouillon, soy sauce, seasoning blends, or salted toppings. If you watch sodium, the quickest win is to season with herbs, citrus, vinegar, garlic, and spices, then salt with a measured pinch.
How To Use Percent Daily Value Without Getting Lost
Nutrition labels use % Daily Value (%DV) to show how much a nutrient in a serving contributes to a daily target. It’s a reference tool that helps you spot highs and lows fast. FDA guidance on reading the Nutrition Facts label explains how %DV works and how to use it for comparison shopping.
For rice, %DV is most helpful for fiber and sodium. Plain brown rice is low sodium. A salty sauce can change that in seconds. Fiber rises when you add legumes and vegetables.
What Changes Nutrition Per 100 g
Two bowls can weigh the same and still differ in calories and macros. A few factors drive that difference.
Water Content After Cooking
Cooked rice is a water sponge. More water in the finished rice means fewer calories per 100 g. Drier rice means more calories per 100 g. If you meal-prep rice, your “day one” rice can weigh differently from your “day three” rice after it dries a bit in the fridge.
Added Oil, Butter, And Sauces
Plain rice is simple. Cook it in oil, finish it with butter, or stir in a sweet sauce and the numbers jump. If you want flavor without a big calorie lift, use spices, acids, aromatics, and fresh herbs first. Add fat with intention when you want it.
Plain Cooked Brown Rice Per 100 g: Fast Reference Table
This table is built for quick planning. The amounts come from the USDA FoodData Central entry linked earlier. Use it as a baseline for plain cooked rice, then adjust for mix-ins.
| Nutrient | Amount Per 100 g | What It Means In Practice |
|---|---|---|
| Calories | 123 kcal | Moderate energy for a cooked grain |
| Total Carbohydrate | 25.6 g | Main fuel source in the bowl |
| Dietary Fiber | 1.6 g | Pair with legumes and vegetables for more |
| Protein | 2.7 g | Helpful, not a stand-alone protein |
| Total Fat | 1.0 g | Most fat comes from toppings and cooking fat |
| Sodium | 4 mg | Stays low unless broth or salty sauces enter |
| Potassium | 86 mg | Small contribution that adds up across the day |
| Iron | 0.56 mg | Minor source on its own |
| Calcium | 3 mg | Trace amount |
| Phosphorus | 103 mg | One of the higher minerals in rice |
Scaling The Numbers To Your Bowl
Once you trust the 100 g baseline, scaling is easy. Multiply by your cooked weight, then divide by 100.
- 150 g cooked rice: 1.5 × the 100 g numbers
- 200 g cooked rice: 2 × the 100 g numbers
- 75 g cooked rice: 0.75 × the 100 g numbers
This method is cleaner than chasing “cups” in a tracking app, and it works even when your rice is wetter or drier than usual.
Portion Comparisons For Typical Servings
When you need a kitchen shortcut, volume helps. Still, grams stay the anchor because volume shifts with packing, moisture, and cooling. Use the weights below as a practical range, then fine-tune with a scale when you can.
| Portion | Cooked Weight You’ll Often See | Scaled Calories (Plain) |
|---|---|---|
| 1/2 cup, loosely filled | 90–120 g | 111–148 kcal |
| 3/4 cup | 135–180 g | 166–221 kcal |
| 1 cup | 180–240 g | 221–295 kcal |
| 1 1/2 cups | 270–360 g | 332–443 kcal |
| 2 cups | 360–480 g | 443–590 kcal |
| Meal-prep bowl (rice + mix-ins) | Varies | Count rice by grams, then add extras |
| Restaurant scoop | Often 250–350 g | 308–431 kcal before sauces |
Brown Rice, Whole Grains, And Everyday Health
Brown rice is a whole grain, and whole grains are linked with better cardiometabolic markers when they replace refined grains. Harvard’s Nutrition Source summarizes evidence that swapping whole grains in place of refined grains is tied to healthier cholesterol, triglycerides, and insulin measures in many studies. Harvard Nutrition Source overview on whole grains is a solid starting point for the pattern and the limits of any single study.
On your plate, the “swap” idea is simple: if rice is your staple carb, choosing brown rice sometimes can lift fiber and minerals. You can also rotate in oats, barley, quinoa, bulgur, or corn as other whole-grain options.
Food Safety And Storage: Make Meal Prep Work
Cooked rice can be safe and convenient when you handle it well. Cool rice soon after cooking, store it in shallow containers, and refrigerate. Reheat it until it’s steaming hot.
If you batch-cook rice, portion it right away. Smaller portions cool faster. For freezer storage, spread rice in a thin layer or use flat bags so it freezes quickly and reheats evenly.
Arsenic In Rice: Practical Risk Reduction
Rice can contain inorganic arsenic from soil and water. Brown rice can carry more because arsenic concentrates in outer layers. You don’t need fear. You need habits that lower exposure while keeping meals realistic.
The FDA notes that cooking rice in excess water, then draining it, can reduce inorganic arsenic by 40–60% depending on rice type. The FDA also describes a “pasta method” ratio of 6–10 parts water to 1 part rice, followed by draining the extra water. FDA tips to limit arsenic exposure from food covers that approach.
Another simple move is grain rotation. If rice is daily for you, swap a few meals each week to other grains. Variety lowers exposure from any single source and keeps meals less repetitive.
Ways To Add Flavor Without Losing Control Of The Numbers
Rice doesn’t need butter to taste good. Start with bold flavor that adds little energy, then add fats only when you want them.
- Finish with lemon or lime juice, then add chopped herbs.
- Cook with garlic, ginger, bay leaf, or a cinnamon stick for aroma.
- Use toasted spices: cumin, coriander, turmeric, chili flakes, or smoked paprika.
- Fold in crunchy vegetables like cucumber, carrots, cabbage, or scallions.
If you want a richer bowl, add fat in a measured amount: a teaspoon of olive oil, a spoon of tahini, or a small handful of nuts. Count it, enjoy it, move on.
Common Tracking Mistakes And Fixes
Mistake: logging raw rice values for cooked rice. Fix: confirm your entry says cooked and your portion is cooked weight.
Mistake: relying on “1 cup” entries that don’t match your scoop. Fix: log by grams when you can, or use the ranges above and stick to one measuring habit.
Mistake: forgetting sauces and cooking fats. Fix: add oil, butter, and sauces as separate entries so your log matches your plate.
Using This Page In One Minute
Pick a rice portion in grams. Start at 100 g cooked if you want a solid baseline. Scale the numbers using the 100 g table. Build the rest of the meal with protein and vegetables. Keep salty sauces and added fats intentional. That’s it.
