I mean, seriously, it's not even a contest. I don't know what kind of sad soy milk availability you have, Sue, but most of the soy milks in my local Whole Foods (and ALL the soy milks in my local supermarket, ShopRite) are enriched with, at bare minimum, calcium, Vitamin D and Vitamin A, and they are basically along the lines of what I and EntropysDad have posted. The more sweetened soy milks are, the lower the protein as compared to sugar. However, the ones I posted (which are representative of the brands with the biggest shelf-space at every single store I've been to) are either equivalent to or superior to milk, nutritionally. The major issues are added sugars and lack of enrichment (even cows' milk is enriched, of course, so it is truly ridiculous to compare enriched cows' milk with non-enriched soy milk), which are easily eliminated with about two seconds of browsing.
Also, to rnrgirl, the soy milks and cows' milks at my local rinky-**** supermarket are the EXACT SAME PRICE for the same size containers. At the Whole Foods, the soy milk is generally CHEAPER than the regular milk. The only exceptions are the difficult to find brands or the ones that use all organic ingredients (such as EdenSoy). But again, think about the price of organic milk and they are comparable.
**Good reasons not to drink soy milk: you love cow milk, you don't like soy milk.**
Bad reasons to not drink soy milk as long as you have even a minimal selection: nutritional differences, price.
