Avena is a plant that is commonly used to make oat-based drinks. It is known for its nutritional value and is often used as a healthy alternative to dairy. Avena-based drinks are typically made by soaking the oats in water and then blending them until they reach a smooth consistency. These drinks are low in fat and free of added sugar, making them a guilt-free indulgence. They are also versatile and can be used in cooking and baking. Avena-based drinks are a popular choice for breakfast or as a complement to tea or coffee.
