Is oat milk healthy?
In moderation. Oat milk sits in the middle of the scale — grade C on the open 2023 Nutri-Score algorithm: fine in a balanced diet, but not a “more is better” drink.
Against
- On the drinks scale anything with calories ranks below water: this has 47 kcal and 4 g of sugar per 100 ml, and little protein to offset it (0.8 g).
A typical serving (cup, 240 ml) has 113 kcal, 1.9 g protein, 3.6 g fat and 20 g carbs. Other amounts in the table.
How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on November 1, 2026. The short food description was written by our language model (AI) — how we check the text.

*Where the vitamin numbers come from
Vitamins and minerals come from the USDA FoodData Central record “Oat milk, unsweetened, plain, refrigerated” (FDC ID 2257046, SR Legacy; public domain), checked October 14, 2026; the record was matched to this food by calories, protein and fat. % DV is per serving, against the FDA Daily Values used on Nutrition Facts labels (2,000-calorie diet). The table lists nutrients that reach at least 2% DV per 100 ml; the rest are absent or trace. Varieties, seasons and brands differ, and cooking in water leaches some vitamin C and B vitamins.
