What is oat milk?

Oat milk is a delicious cow milk alternative! It’s fresh, sweet and it has a more neutral taste than almond or soya milk. I love to add it to my cereals for breakfast!

Plant-based milk has become very popular these days and oat milk nutrition makes it an excellent choice. It’s a good source of vitamins, minerals, and fibers. Do you have allergies or intolerances? It’s naturally free of soy, nuts, lactose, and gluten if it’s labeled gluten-free oatmeal.

Want to reduce your CO2 emissions? The cereal “oat” is a nutrient-rich food that grows easily in our temperate regions. Which makes it one of the most eco-friendly milk of all plant-based milk.

In addition, the recipe is very easy to make at home. Oat flakes are available without packaging in any bulk store. Hence, its price is really lower than any other milk bought in a carton.

Is it a good cow milk’s substitute?
