Some people can’t do dairy. Some people just can’t do whey protein. That’s why we’re big fans of PureFit and their soy protein source. Why do they use soy? We spoke with Rob Dorf from PureFit about it. Here’s what he had to say: I actually get this question a lot.  It’s actually one of my favorite questions, and it also can be one of the most difficult decisions to defend.  First and foremost, soy is one of the most useable protein sources in the body.  It is a complete protein. Additionally, it is estimated that 30-50 million Americans have some digestive adversity to dairy.  That is a staggering number and roughly equates “up to 15% of all Americans.”  Guess what? I am also lactose intolerant.  Sure, I can take a Lactaid and avoid some of the gas and bloating, but in general, dairy cause “gastrointestinal discomfort.” When I started PureFit in 2001, there was only one obvious choice to help PureFit reach the 18 grams, or 30%, protein, we wanted each bar to pack.  That choice was Non-GMO soy protein isolate from right here in the United States. [product_grid id="139850"] There are other reasons too: Soy is generally considered the next best useable protein in the body, and if I had to guess, it is the #1 source of protein for vegans.  Whey is a bi-product of cheese, which of course, is made with dairy from cows.  Vegans have long been big supporters and believers in soy. Soy protein, in our opinion, tastes better.  Whey can often have a chalky aftertaste. Soy is considered, very healthy, despite what you may have heard or read.  Without sounding too defensive, soy is still an unbelievably healthy ingredient and has been linked, in multiple studies, to lowering cholesterol levels. I compete in all types of endurance races from running, cycling, mountain biking, and I even was a chase vehicle in the Baja 1000.  When you eat clean food, with the right type of protein for your body, and in the right amount (30%) you are going to perform better.  I don’t care if you’re an “on the go soccer mom, or a CEO training for your next Ironman,” PureFit’s choice to use non-dairy protein in our original line of bars was the safe and smart decision.  Try one, I think you’ll feel that PureFit bars will fuel you to the finish line and not the bathroom.
