Animal fat/milk with the hormones of a different mammal seem to be causing a lot of problems. Planetary and health related.

And the low fat milk in the carton is pretty far from natural, where oat milk in example seems to be pretty simple process based on quick googling:

Of course any industry can make anything ultra processed, like oat milk, but the generalization was wee bit hefty here.

With dairy, is especially important to go for the organic options. In generally (excluding parts of Asia), humans have been cultivating livestock and consuming dairy for tens of thousands of years. Our bodies are evolved for it, but not the ultra processed goop and all the added sugar everywhere. If you want to avoid animal products, it’s probably best to just drink water than these engineered “milks”.

According to Wikipedia, organic food does not offer any advantage over ordinary food.
