Milk is simply not human food and is harmful to our biochemistry. The milk of almonds (and other nuts) is a great alternative to regular milk, particularly in cookery. However, soy milk must be avoided. Fruit juices, even when freshly made, are glycemic— for this reason, they get the "Amber" classification. It is much better to eat the fruit itself.

Sugar-sweetened carbonated drinks and colas are high-glycemic and disrupt bone building. ~Paleo in a Nutshell p.81
