Rice Milk
Rice milk is a plant-based beverage made from milled rice and water, commonly used as a dairy alternative. It is naturally low in protein and high in carbohydrates, and is typically fortified with calcium and vitamins to improve nutritional comparability to cow's milk.
Also known as: rice beverage, rice drink, rice-based milk alternative

Rice milk is produced by grinding rice (usually white or brown rice) with water, then straining the mixture to create a smooth liquid. The beverage has gained widespread availability in Western markets as a dairy substitute and appears in coffee, cereals, smoothies, and cooking applications where a neutral-flavored liquid is needed. Commercial rice milk products are almost always fortified with calcium, vitamin D, and vitamin B12 to address nutritional gaps inherent in the base ingredient.
Nutritionally, unsweetened rice milk contains approximately 1 gram of protein per cup and around 113–120 calories, with minimal fat (roughly 2–2.5 g). Unlike dairy milk, it provides no naturally occurring calcium—fortification is the sole source in most products. Rice milk is gluten-free and does not contain lactose, making it tolerable for people with lactose intolerance or celiac disease. The carbohydrate content is substantial at approximately 22–25 grams per cup in unsweetened varieties, which is considerably higher than most other plant-based milks. Because rice undergoes processing to create the milk, fiber is largely absent unless specifically added back. The beverage has a high glycemic index due to its carbohydrate composition and limited fiber, which means it raises blood glucose more rapidly than whole grains.
Blood Sugar Response
Rice milk has a high glycemic index (approximately 86) and a correspondingly high glycemic load, making it a rapid source of carbohydrate absorption. This characteristic is relevant for people managing blood sugar or type 2 diabetes, who may experience faster postprandial glucose elevation compared to lower-glycemic alternatives like unsweetened almond or soy milk. Pairing rice milk with protein or fat-containing foods slows absorption and moderates the glycemic response.
Allergens and Sensitivities
Rice milk is naturally free of the major allergens (dairy, soy, tree nuts, peanuts, and gluten), making it suitable for individuals with many common food allergies. However, some commercial products may be processed in facilities that handle allergens. Rice products in general can contain trace levels of inorganic arsenic; for adults consuming rice milk occasionally as part of a varied diet the exposure is considered low, but rice milk should not be a primary milk source for infants under 12 months due to insufficient nutritional density. For toddlers aged 1–5, UK and US health authorities advise that rice drinks are not ideal owing to potential arsenic exposure, and fortified oat or soy milk are generally preferred for that age group.
Frequently Asked Questions
Is rice milk a good substitute for dairy milk?
Rice milk can replace dairy milk in beverages and cooking, but it is significantly lower in protein (roughly 1 g vs. 8 g per cup) and contains no naturally occurring calcium or vitamin D. Fortified varieties bridge the micronutrient gap, but protein content remains low. It is best viewed as a beverage alternative rather than a nutritional equivalent to cow's milk.
Does rice milk spike blood sugar?
Yes. Rice milk has a high glycemic index (around 86) and raises blood glucose rapidly due to its high carbohydrate content (approximately 22–25 g per cup) and lack of fiber. People managing diabetes or prediabetes should consume it in moderation or pair it with protein and fat to moderate the glycemic response.
Is rice milk safe for infants and young children?
Rice milk is not appropriate for infants under 12 months, who require breast milk or iron-fortified infant formula. For children aged 1–5, health authorities in the UK and US advise against rice milk as a main drink due to potential inorganic arsenic content and lower nutritional density; fortified soy or oat milk are generally preferred alternatives for toddlers.
Does rice milk contain arsenic?
Rice products, including rice milk, may contain trace amounts of inorganic arsenic. For adults consuming rice milk occasionally as part of a varied diet, exposure is considered low risk. Infants and young children are more vulnerable, which is why dietary variety and the use of lower-arsenic plant milks are recommended for young children by the FDA and NHS.
