Carbohydrates in a Serving of Brown Rice
A single Serving Of Brown Rice delivers over 45g of complex carbohydrates and 3.5g of fiber, with negligible amounts of sugar. Complex carbohydrates are nutritionally superior to simple carbs due to their fiber and nutrient content.
The high fiber content in a serving of brown rice promotes slower digestion, leading to sustained energy release. Brown rice also registers as medium on the glycemic index (GI), ranging from 64 to 72, according to the American Diabetes Association (ADA). Even with a moderate GI, the ADA still recommends brown rice as a beneficial whole grain choice.
The Glycemic Index measures how quickly carbohydrate-rich foods elevate blood glucose levels. Choosing foods with low to medium GI ratings, like a serving of brown rice, can help maintain stable blood sugar levels. Food combinations can also influence the overall GI impact of a meal.
Fat Content in Brown Rice Serving
A serving of brown rice contains minimal fat, with only 1.2g, primarily composed of mono and polyunsaturated fats. Unsaturated fats are recognized as healthy fats, largely derived from plant sources and fatty fish.
The American Heart Association (AHA) advises that 25%–35% of daily caloric intake should come from unsaturated fats. Preparing a serving of brown rice without added oils or butter results in a virtually fat-free dish.
Protein in a Serving of Brown Rice
Each 1-cup cooked serving of brown rice offers more than 4g of plant-based protein. Proteins are classified as complete or incomplete. Brown rice, similar to most grains, provides incomplete protein, meaning it lacks some essential amino acids needed to form a complete protein. Therefore, brown rice protein is often combined with other plant proteins, such as pea protein, in products like organic protein powder to create a complete protein source. Dietary guidelines from the USDA suggest that 10%–35% of daily calories for adults should come from protein.
Vitamins and Minerals in Brown Rice Serving
Unlike white rice, brown rice retains its nutrient-rich bran layer, which is abundant in essential vitamins, minerals, and phytochemicals. These include B vitamins, fiber, essential amino acids, flavonoids, minerals, and antioxidant compounds. A serving of brown rice is also a source of phytic acid, an anti-nutrient that research indicates has antioxidant properties and potential medicinal benefits.

Calories in Cooked Brown Rice Serving
A 1-cup (195g) serving of cooked brown rice contains approximately 218 calories. The caloric distribution is roughly 86% from carbohydrates, 8% from protein, and 6% from fat.
Health Benefits of Including a Serving of Brown Rice in Your Diet
Brown rice is a naturally gluten-free, whole grain option suitable for individuals with celiac disease, wheat sensitivity, or non-celiac gluten sensitivity. Its rich phytochemical content is also recognized for its role in disease prevention.
The health advantages of brown rice are largely attributed to the antioxidants, fiber, and beneficial chemical compounds found in its bran layer. Studies have linked brown rice consumption to a wide range of health-promoting properties.
Nutritious Energy Source from a Serving of Brown Rice
Brown rice is packed with essential nutrients, notably surpassing white rice in nutritional value. These nutrients include protein, lipids, and various minerals and vitamins. As a cereal grain, rice is a primary source of dietary carbohydrates, and a significant portion of daily energy in many diets comes from carbohydrates.
The starch content of a serving of brown rice makes it an effective energy source. It’s also richer in dietary fiber than white rice because its outer bran layer is intact. Including whole grains like brown rice in your diet can help lower the risk of developing certain chronic illnesses.
Healthy Fiber Provided by Brown Rice
Dietary fiber is crucial for digestive health, blood sugar regulation, weight management, and heart health, among other benefits. Brown rice is an excellent source of dietary fiber. A single serving of cooked brown rice meets about 13% of the daily recommended fiber intake.
Reduced Risk of Chronic Diseases with Brown Rice Consumption
Incorporating whole grains like brown rice into your diet is associated with a decreased risk of chronic diseases. Brown rice exhibits anti-diabetic, anti-cholesterol, cardioprotective, and antioxidant properties. It aids in post-meal blood sugar control due to its lower glycemic index compared to white rice (55 vs. 64).
Health-Boosting Phytochemicals in Brown Rice
Brown rice is abundant in health-enhancing phytochemicals, including dietary fiber, functional lipids, essential amino acids, phytosterols, phenolic acids, flavonoids, anthocyanins, proanthocyanins, tocopherols, tocotrienols, minerals, gamma-aminobutyric acid (GABA), and γ-oryzanol.
Phenolic compounds in brown rice offer numerous health benefits, including anti-inflammatory, hypoglycemic, anticarcinogenic, antiallergenic, and antiatherosclerotic effects. These include phenolic acids, flavonoids, tannins, coumarins, and stilbenes.
Prevention of Anemia with Brown Rice
Brown rice is a source of iron, phosphorus, magnesium, potassium, zinc, and copper. Consuming white rice, which is low in trace minerals, is considered a contributing factor to anemia and zinc deficiency disorders, particularly in developing countries. The WHO estimates that over 30% of the global population suffers from anemia, predominantly due to iron deficiency. Brown rice contains a higher iron content than other processed rice types.
The iron and mineral content in brown rice are significant for health and anemia prevention, especially given the high global consumption of rice.
Allergies to Brown Rice
While rice allergy is not common, it can occur, especially in Asian countries where rice is a dietary staple. Individuals sensitive to corn, soy, and barley may also exhibit sensitivity to rice.
Potential Adverse Effects: Arsenic in Brown Rice
Arsenic, a naturally occurring environmental toxin, is found in trace amounts in most foods and drinks, including brown rice.
Arsenic exists in two forms: organic and inorganic, with inorganic arsenic being more toxic. Brown rice tends to have higher levels of inorganic arsenic due to contaminated irrigation water that can leach into the soil where rice crops are grown. Cooking water can also contribute to inorganic arsenic levels in brown rice.
However, this does not necessitate eliminating brown rice from your diet.
According to a report from the Food and Drug Administration (FDA), the estimated inorganic arsenic concentration in brown rice is 154 parts per billion (ppb), compared to 92 ppb in white rice. The FDA suggests that these levels do not pose an immediate health risk but could present a risk with long-term exposure.
Therefore, individuals who consume significant amounts of brown rice daily may benefit from moderating their intake. The FDA recommends a balanced diet to mitigate potential adverse effects from overconsumption of any single food. The FDA has also established limits for inorganic arsenic in infant rice cereal.
How to Reduce Arsenic Levels in Brown Rice
- Rinse brown rice with filtered water low in arsenic before cooking.
- Cook brown rice in ample filtered water low in arsenic, using a 6-to-1 water-to-rice ratio.
- If rice is a dietary staple, consider alternating with white rice.
- Vary the types of grains consumed throughout the week.
- Consume brown rice in moderation as part of a diverse diet.

Varieties of Brown Rice
Brown rice comes in several varieties, including short-grain, medium-grain, and long-grain. Each type has a nutty flavor, but grain size affects the cooked texture. Brown rice also requires a longer cooking time than refined white rice.
Short-grain brown rice is short, plump, and nearly round. It becomes soft, tender, and sticky when cooked.
Medium-grain brown rice is plumper and larger than short-grain but smaller than long-grain. It cooks up moist and tender with less stickiness than short-grain.
Long-grain brown rice is slender and long, more so than medium- and short-grain varieties. It cooks into light, fluffy, separate grains and is commonly used in dishes like rice pilaf.
Storage and Food Safety for Brown Rice
Brown rice is suitable for long-term storage if kept in an airtight container away from extreme temperatures and direct sunlight. Store it in pest-resistant containers and periodically check stored brown rice for any signs of insects.
How to Prepare Brown Rice
Brown rice is versatile and can be prepared in numerous ways. It can be cooked in water, broth, milk, tomato sauce, or other seasoned liquids. It can also be added directly to liquid-rich dishes like soups, stews, or one-pot meals.
Cooking methods include using a rice cooker, stovetop, microwave, or pressure cooker. Brown rice can be seasoned to taste, either sweet or savory, and enjoyed hot or cold, as a base for curries and stir-fries, or as a side dish.
