Oat milk is a scam. Soy milk is the only milk alternative being and doing exactly what it says and it's ass in coffee. The rest are seriously problematic for a variety of reasons, the two big ones for me being oat milk which processes through the human body as pure sugar, and almond milk which isn't the miracle health product it's been sold as, as well as being extremely detrimental to our environment to grow for mass production. Probably the worst thing you can do with almonds to make things worse for the environment is turn them into liquid, cause as anyone who's ever made Juice knows: it takes more input material than you get out by a long shot. Now imagine juicing tiny little almonds. Anyway, you've all been warned!
