Nondairy milk may have begun as a lactose-free alternative for vegans or nondairy eaters, but the rise in popularity can be attributed to much more than being a must-have swap. The options are endless: almond milk, soy milk, hemp milk, rice milk, and more. But there’s a new kid on the block that’s getting a lot of attention from nutritionists and foodies alike: oat milk.

Oat milk consists of steel-cut oats or whole groats that are soaked in water, blended, and then strained with a cheesecloth or a special nut milk bag. Oat milk is a good choice for anyone who is allergic or intolerant to dairy and/or nuts, as well as those looking to limit saturated fat in their diets.

Oat milk is the clear winner when it comes to fiber. “Cow’s milk has 0g fiber, almond and soy have 1 gram of fiber per serving—so oat milk with 2 grams of fiber is the highest. Oat milk does tend to be higher in carbohydrates.
