Quick search says milk contains twice protein as oat milk, and moreover more complete one. However for protein intake I would recommend soy products that are super healthy, cheap and contains fibers. The only plant milk I drink is a dip in my morning beverage and for cooking cakes.
But if you’re protein intake comes substantially from milk, indeed you should consider that.
You already got the oat. Got a blender? Grind those little flakes with water and a spoon of your favorite oil. Et voilà !
Pro tips:
- filter for extra smoothness but no need if you intent to mix with whole oat flakes
- 1h in the fridge and mix again for double extra smoothness
- pinch of salt or cinnamon or cacao… yummi
- bored of oat? Check your supermarket shelf for other ideas. (Soy need to be cooked then blend then filter).
