this is a fun question and i'm glad you asked! first of all let me set your mind at ease on one point: soy milk does not contain estrogen. the benefits of soy in easing menopausal symptoms in women is still debated but that doesn't mean it contains estrogen. it doesn't. in asia soy is widely consumed by both sexes and i don't think asian men have worse man-boobs than other men. men and women both produce estrogen and testosterone. as men age they produce less testosterone which may allow estrogen to play a more dominant role which can lead to man-boobs. in women aging reduces estrogen production which may allow their natural testosterone to play a more dominant role and they may get mustaches. i ask you: which is less fair? but to your question: almond milk should not have any estrogenic effects so drink away! assuming you're not allergic to almonds at least. hope this helps!
i've heard soy milk contains estrogen and causes "man-boobs" if consumed by men. does almond milk have the same issue?
