Which Milk Is Lowest in Sugar?

Aug 31, 2026

Unsweetened almond milk is the clear winner for lowest sugar—typically 0–1 g per cup (240 ml). Unsweetened soy, coconut, and cashew milks are also very low (about 1–3 g), while regular cow’s milk has around 12 g of natural lactose per cup.

Key point: Always check the label for “unsweetened” and total sugar—many flavored or “original” plant milks have added sugar.
