Ever wonder what causes gluten sensitivity or celiac disease? Zonulin is the protein that causes the 'gates' or openings between the cells making up the lining of the small intestine to open and close. These openings are called tight junctions and when zonulin gets excessive, a leaky gut ensues. Leaky gut is a problem that must be handled with gluten intolerance. The leaky gut perpetuates gluten's negative impact on other parts of the body. It can also initiate autoimmune disease. For people with celiac disease and gluten sensitivity staying clear of zonulin is vital to your health. That’s why RAW Nature’s Fuel bar are Gluten Free. Fuel the body…Calm the Crave!
