% Daily Value is how much 100 g contributes to the FDA Daily Values for adults and children 4 years and older, the figures on US nutrition labels; a dash means there is no Daily Value for that nutrient. "Not reported" means USDA has no measurement for this food, not that it contains none.

How Oat Milk fits common diet targets

Energy density

very low
  • Net carbs are total carbohydrate minus fiber: 5.4 g − 0.5 g = 4.9 g per 100 g. Low-carb plans usually count these.
  • Protein per 100 kcal compares how much protein each food gives for the same calories: Oat Milk gives 1.5 g.
  • Energy density is calories per gram. At 0.45 kcal/g, Oat Milk is very low on the CDC's scale (very low below 0.6, low to 1.5, medium to 4, high above 4); lower-density foods give a larger portion for the same calories.

Logging Oat Milk: what to know

Oat milk comes to 45 kcal per 100 g, carrying 5.4 g of carbohydrate and 2.3 g of fat. Almond milk shows 0.3 g of carbohydrate per 100 g, so the two cartons are not interchangeable in a log. Barista and sweetened versions vary, so check the label against this generic entry.
