Oat (avena) benefits

Oats are a superfood packed with fiber, vitamins, and minerals besides being naturally gluten-free, so perfect for people with specific dietary needs.

Fiber has been proved to be good against type 2 diabetes, cardiovascular disease, and some types of cancer; besides being very important for a well-functioning digestive system.

But something important to note is that you should always choose the type of oats to consume. For the most health benefits, you can opt for old-fashioned, rolled, or steel-cut oats instead of quick oats because the last is lower in fiber than the others.

Notes

  • Use room temperature water so the sugar would be easier to dissolve.
  • Adjust sweet to your taste by adding more or even less that the recipe suggest.
  • Do not add ice to the pitcher unless you intend to serve all the drink at once, otherwise it will dilute and become flavorless.
  • Use other types of sweeteners if you want to. Such as monk fruit, stevia, regular white sugar, or even honey.
  • Replace 2 cups of water with 2 cups of your favorite plant-based milk to make a creamy version. I recommend almond or coconut milk.

Storage Suggestions

This oat horchata keeps nicely in the fridge for up to 3 days, just make sure to store it in a large container with a tight lid to prevent it from absorbing other smells.

You can also store the oat’s concentrate first. Blend soaked oats with cinnamon and a bit of water as indicated in the recipe. Place the mixture in a container and freeze for up to 3 months. When needed, thaw it and use it to make your agua de avena.

  1. The sugar pictured here isn’t traditional brown sugar (like you use in cookies). Is this cane sugar pictured? What type of “brown sugar” do you actually use?
