I wish my local grocery stores had a better selection. I use Silk Unflavored Almond Milk, but understand it has some preservatives that I'd rather not have. Since we don't have a whole foods (or competitor) within 100 miles, I'll have to make due.

most almond/hemp/soy/ etc have additives and one of the bad ones is carrageenan..it's an algae and there is a belief that anyone with digestive issues can further damage themselves.It's used a thickener.Most milks with have this and if they don't they are usually sweetened as the algae works to thicken then thin milks.
It's very easy to make your own if you have the time.

I use almond milk in my protein shakes (when I have them) and in my coffee everyday. But you're right, the Silk preservative kills me. I just checked out that homemade version and it looks great! only thing is that I would have to make it 2-3 times a week since it says it only keeps in the fridge for 3 days

Any other more paleo friendly, affordable, and stable options? ha, I think I am asking a lot here.

I drink flax milk in my protein shakes and use it to mix in with my chia cereal. I think its pretty tasty myself.

Drinking it just by itself can be kind of rough, but for use in other things, its pretty good.

I just posted a 'question' and maybe I just found a little insight here...I hv been making smoothies almost every morning and hv not lost much of anything, plus I hv been gassy I knew there was something in my smoothie. I changed from coconut milk to almond. I changed my pro pwdr to vegan pro powder/Vega Preformance. I even started to use fresh greens instead of chocolate amazing grass...just four days a go I stopped my wonderful smoothies and have a sm snack of let's say fruit &cheese, then a full breakfast after workout of eggs, greens and berries.

I thank you for this post topic and all the responses..it only goes to show me that even what we think is better still isn't the best..
