I haven't dived into plant-based milks and health risks/benefits too much. What I can tell you is that Animal based Milk in general is not healthy, they are high in saturated fats, have a too high calcium and estrogen concentrations and increase the risk to prostate cancer[1], ovarian cancer [2], uteri cancer [2] and other health risks.
Do note that a lot of pro-milk studies are industry backed. The new Canadian food guide has discarded all industry backed studies and based on science created a new food guide [3]. This food guide removed the "recommended" glass of milk based on these studies with water.
