You’re steering clear of dairy, soy and nuts, so rice milk looks like the safe, wholesome pick. It’s made from a grain, after all, and a cup of cooked long grain brown rice carries 3.2 grams of fiber, according to USDA.
The carton tells a different story. USDA’s unsweetened rice milk lists about 0.7 grams of fiber per cup, and every Rice Dream label we checked lists 0 grams, including the one made with brown rice.
Rice milk fiber, label by label
These figures come from USDA FoodData Central reference records and Rice Dream labels. A cup of cooked long grain brown rice shows what the whole grain brings.
| Drink or food | Serving | Fiber | Calories | Protein | Sugar |
|---|---|---|---|---|---|
| USDA rice milk, unsweetened | 1 cup (240 g) | 0.7 g | 113 | 0.7 g | 12.7 g |
| Dream Original Calcium + Vitamin D | 240 g | 0 g | 120 | 0 g | 11 g |
| Rice Dream Organic Original Unsweetened | 240 g | 0 g | 60 | 0 g | 1 g |
| Dream Blends Rice and Quinoa Original | 1 cup | 0 g | 90 | 1 g | 7 g |
| Long grain brown rice, cooked | 1 cup (202 g) | 3.2 g | 248 | 5.5 g | not compared |
The rice and quinoa blend sounds like a whole grain upgrade, yet it lists 0 grams of fiber too. Adding a second grain to the base doesn’t bring the fiber along with it.
The newest unsweetened Rice Dream stands out for a different reason. At 60 calories and 1 gram of sugar, it’s far lighter than the classic carton, though its fiber line is still empty.
Why rice milk keeps so little of the grain
Mayo Clinic notes that refined grains lose their outer bran layer, which holds much of the fiber. Rice milk goes a step further, since the grain is blended with water and then processed into a smooth drink.
Rice Dream’s unsweetened carton lists “organic rice milk (water and organic hydrolyzed rice)” as its base. Hydrolyzed means the rice starch has been broken down into smaller pieces, which helps create a sweet, drinkable liquid.
Dream Original uses “organic brown rice (partially milled),” meaning some of the bran has been removed before it reaches the carton. Either way, the label shows 0 grams of fiber.
Where all that sugar comes from
USDA’s rice milk record is labeled unsweetened, yet it lists 12.7 grams of sugar per cup. Dream Original lists 11 grams, and its ingredient list has no added sweetener at all.
The sugar comes from the rice itself as its starch is broken down. That puts plain rice milk close to a cup of 2% dairy milk, which has about 12 grams of sugar, none of it added.
Rice Dream’s newer unsweetened carton is the exception, at 1 gram of sugar per serving. If sugar is on your radar, that one gap between cartons matters more than anything else on the label.
Rice beverage nutrition beyond fiber and sugar
Fortification carries most of rice milk’s nutrition. USDA’s unsweetened rice milk lists 283 milligrams of calcium per cup, about 22% of the Daily Value, plus 2.4 micrograms of vitamin D and 1.5 micrograms of vitamin B12.
That B12 amount is about 63% of the 2.4 microgram Daily Value. USDA also lists 0.68 milligrams of manganese per cup, about 30% of the Daily Value, which comes from the rice.
Protein is close to zero, at 0.7 grams per cup in USDA’s record and 0 to 1 gram on the Dream labels. Fat is low at about 2.3 to 3 grams, with no saturated fat in the USDA record.
Sodium ranges from about 80 to 140 milligrams per cup across the records here, roughly 3 to 6% of the Daily Value. Potassium is low, at about 65 milligrams per cup in USDA’s record, far below the 390 milligrams in a cup of unsweetened soy milk.
Magnesium lands at about 26 milligrams per cup, around 6% of the Daily Value. That’s a modest amount, and like the manganese, it comes from the rice rather than from fortification.
Weighing rice milk against oat, soy, pea or almond? Our comparison charts set fiber, protein and calcium side by side for the popular options.
How much rice milk would match a bowl of rice?
Put the numbers side by side and the gap is hard to miss. To get the 3.2 grams of fiber in one cup of cooked brown rice, you’d need roughly four and a half cups of USDA’s rice milk.
That much rice milk adds up to about 500 calories and well over 50 grams of sugar. The bowl of brown rice brings the same fiber for about 248 calories, along with 5.5 grams of protein.
Brown rice is also a standout for manganese, at about 2 milligrams per cup, or 86% of the Daily Value. Rice milk keeps some of that, but only around a third as much.
Vanilla, chocolate and horchata rice drinks
Rice Dream also sells vanilla, chocolate and horchata style drinks. Their USDA listings run from about 54 to 67 calories per 100 grams, higher than the plain unsweetened carton at 25.
Flavored versions are built for taste rather than nutrition, so read their sugar and fiber lines before making one a daily habit. Even the plain cartons we checked list 0 grams of fiber, so there’s no fiber gain to expect from flavoring.
Rice milk for people avoiding dairy, soy and nuts
If you avoid several common allergens at once, rice milk may fit. The Rice Dream ingredient lists we checked contain water, rice, plant oils, minerals, vitamins, salt and, in some cases, vanilla or xanthan gum, with no dairy, soy or nuts.
That makes it a useful option for some households, but it’s not a protein replacement. If rice milk is your main milk, plan other protein sources through the day, since a cup supplies almost none.
Formulas also change, so check each carton’s allergen statement rather than relying on the brand name alone.
Rice milk among the plant drinks
On fiber, rice milk sits with almond, cashew and coconut near the bottom. The oat milks we checked list 1 to 2 grams per cup, and Silk’s soy milk labels list up to 2 grams.
On protein, rice milk trails nearly everything. Soy milk lists 7 to 9 grams per cup and pea milk lists 8, compared with under 1 gram in rice milk.
Calories vary more than you’d expect. USDA’s rice milk has 113 calories per cup, close to oat milk at about 110, while Rice Dream’s newer unsweetened carton has just 60.
A quick checklist for buying rice milk
- Sugar: compare total sugar, since plain cartons range from 1 to about 13 grams per cup.
- Calcium: look for at least 20% of the Daily Value, as some records don’t declare calcium at all.
- Vitamin D and B12: check that both appear in the ingredients or on the label.
- Protein: expect 0 to 1 gram, and plan to get protein elsewhere.
- Fiber: expect 0 to under 1 gram, whether the rice is white or brown.
- Allergens: read the allergen statement on each carton, even within one brand.
Building fiber around rice milk
Rice milk’s mild sweetness pairs well with fruit and whole grains that bring the fiber it lacks. These combinations use Dietary Guidelines fiber values.
- Bran cereal bowl: three quarters of a cup of bran flakes (5.5 g) with rice milk and half a cup of blackberries (3.8 g) brings about 9 grams.
- Rice pudding, upgraded: make it with brown rice (3.2 g per cup) and rice milk, then top with a quarter cup of chopped dates (3.0 g).
- Pumpkin spice smoothie: half a cup of canned pumpkin (7.1 g) blended with rice milk and cinnamon makes a sweet drink with real fiber.
- Chia overnight pudding: two tablespoons of chia seeds (8.2 g) set in rice milk gives you a pudding with more than eleven times the fiber of the milk alone.

Rice milk and your fiber day
Mayo Clinic suggests about 25 grams of fiber a day for women and 38 grams for men up to age 50. A cup of rice milk covers about 3% of the lower target at best.
Mayo Clinic also recommends adding fiber gradually and drinking plenty of fluids, since too much too fast can cause gas, bloating and cramping. Rice milk can play the fluid role while your meals take care of the fiber.

The caveat hiding in the word unsweetened
On rice milk, “unsweetened” doesn’t guarantee low sugar. USDA’s unsweetened record still lists 12.7 grams per cup, because the sugar forms as the rice starch breaks down rather than being added.
If you’re watching sugar, read the total sugar line every time. The gap between about 13 grams and 1 gram per cup can sit between two cartons with nearly the same name.
Rice milk fiber: what people ask
Does rice milk have fiber?
Barely. USDA lists about 0.7 grams per cup for unsweetened rice milk, and Rice Dream labels list 0 grams.
Does brown rice milk have more fiber?
Not in the cartons we checked. Dream Original uses partially milled brown rice and still lists 0 grams of fiber per serving.
Why is rice milk so high in sugar?
The rice starch is broken down into sugars during processing. USDA’s unsweetened rice milk lists 12.7 grams of sugar per cup with no sweetener added.
Does rice milk have protein?
Almost none. USDA lists 0.7 grams per cup, compared with 7 to 9 grams in soy milk and 8 grams in pea milk.
Is rice milk good for people with allergies?
It can be. The Rice Dream ingredient lists we checked contain no dairy, soy or nuts, but check each carton’s allergen statement.
Is rice milk a good source of calcium?
Fortified versions are. USDA’s rice milk lists 283 milligrams per cup, about 22% of the Daily Value.
How can I add fiber to rice milk?
Pair it with high fiber foods. Two tablespoons of chia seeds set in a cup of rice milk add about 8.2 grams.
