I would prefer cow's milk. I like the taste better, and I think it's more nutritious. It's what I drank for most of my life.
But, I've now become mildly lactose intolerant. And my high cholesterol remains a concern. Lactose intolerance runs in my family. My Father had it, my second son had it at a very young age. Now I've finally developed it. Taking Lactaid pills and other fixes don't work very well for me.
So dairy milk is off the menu, and almond milk is the best option for me. It's got high calcium, which I need at my age. It also works for most of the things I used dairy milk for: breakfast cereal, tea & coffee, swallowing my pills, adding to some soups and other foods, and so forth.
I'm now happy with it, and the price is usually less than dairy milk. In fact, I try to buy it on specials, I practically steal it. And it seems to last a longer time in our refrigerator than dairy milk.
When we travel I also buy "Shelf Stable" containers of it (similar to the high temperature [HT] dairy milk I bought when I lived in Germany), that don't require refrigeration until opened, in case I can't find it easily at our destination. I just throw it in the car trunk, don't have to ice it or anything.
Here's the almond milk brand I like the best, but tastes are individual:http://almondbreeze.com
