For me, I guess there currently is no perfect vegan protein powder. Each has its pros and cons and is good in its own way. I think something that I forgot when I began this search was that protein powder is a supplement and not a whole food. I was trying to find a powder to count as a major source of my protein intake (apparently healthy adults optimally have around .8 g protein per kg of body weight per day*). However, I enjoy getting most of my nutrients through complete foods and not isolates, because a whole food is more than the sum of its parts.
After this search and after experiencing several slight headaches, slight dizziness, tiredness, some weight gain, and a strength training workout during which I simply could not lift the weight due mostly to (I believe) lack of enough protein, I think I will be straying further away from the vegan path. (I can only consume so many beans [fiber!] and soy in my diet!)
According to Nina Planck's Real Food, humans are "omnivores with bodies designed to eat plant and animal foods...[and] [t]here are no traditional vegan societies" (Planck, 21-22). Of course, everyone has their own opinion, and what works for one person may not work for another. While many people have successfully gone vegan, at the moment, a vegan diet is not for me. Remember, the right kind of diet is one that works for you, and there are many diets out there. However, I will try to keep animal products in my diet at a minimum for now. (Things can always change. And it's too bad I can't afford local meat from a farm like Stillman's more often!) In future posts, I hope to discuss veganism, vegetarianism, industrial meat, etc.!
And as a last note, all is not lost in my vegan protein powder world! I will probably continue to incorporate vegan protein powder in my diet, but just in small and unnoticeable amounts (baking?!). Most likely, I will continue with hemp protein; but whenever I'm feeling up to it, I have heard some good things about NutriBiotic's rice protein. Their plain rice protein only has one ingredient, too!: "enzymatically processed rice protein from whole grain brown rice."
