Oat Milk: Nutrition, Pros & Cons
Oat milk is a popular plant-based dairy alternative made from liquefied oats. It is naturally lactose-free and offers a creamy texture, making it highly versatile for beverages and cooking. While it contains heart-healthy beta-glucans, commercial varieties often contain added sugars, oils, and stabilizers, and have a higher carbohydrate content and glycemic index than other plant-based milks.
