As I’ve gotten older, my tolerance for milk has lessened. I do love ice cream and I wont give that up, but I have found that there are many alternatives to dairy. I started using almond milk in my cereal and really enjoy it. Then I see oat milk starting to come to light in the past year or so.

What’s it’s all about?

Oat milk is made from oats, that’s it. The texture is close to dairy milk with a lovely, nutty flavor.

Oat milk is not a new fad, it actually has been lurking for a while but is just being noticed now as so many people have come to realize their food issues.

If you have a nut allergy, can’t tolerate dairy, on a keto or low carb diet, vegetarian/vegan or just want a milk other than almond or soy milk, Homemade Oat Milk is a delicious, plant-based alternative.

Why do I need to make my own when I can buy it?

First and foremost, you control the ingredients. Store bought, from what I see add so many unpronounceable ingredients. Also, not all store-bought oat milk are  gluten-free if you use gluten-free oats you can guarantee the outcome.

Oat milk is high in protein, great for use as a coffee creamer (just add vanilla, honey or sugar), made into lattes, cappuccinos, and froths up really well.

Phytic acid and raw oats

Phytic acid is all raw oats and can hinder the absorption of some nutrients. If you are concerned about this, you can rinse the oats after soaking and discard the soaking liquid and replace with fresh water.
