Alternatives to dairy milk have been surging in popularity in the last few years, chief among them almond milk. Yet almond milk is practically devoid of nutrients.

By themselves, almonds are protein powerhouses. But a typical glass of almond milk, by volume, is just about 2% almonds and contains almost no protein. And all the vitamins inside are added. So if you're looking for a truly healthy alternative, opt for soy, skim, or low-fat milk.
