Quite honestly, this is the best milk replacement I think there is. It may not taste as good as milk by itself, but to me it makes shakes just as creamy and flavorable as regular milk. Heck, I actually like it straight up too.
The only kind I get is made by Blue Diamond Natural. It's important to get the UNSWEETENED vanilla or chocolate flavor. Here's a link to the stats:
For those who were too lazy to go there, I'll give you the gist (for the vanilla unsweetened flavor):
Cals (per 8oz): 40
Fat: 3 grams
Carbs: 2 grams
Fiber: 1 gram
Sugar: 0 grams
Protein: 1 gram
Ingredients: ...eh...I'm not typing them out. But the first two are purified water and almonds.
Most grocery stores carry this brand, HOWEVER it is rather hard to find the unsweetened variations. Your best bet is your local health food store.
This is a great option if you love rich, creamy shakes and want to stay clean. There's simply no better way to do it than this IMO. Also great for those who are lactose intolerant.
Let me know if you decide to give it a go and tell me what you think.
