My 14 yo son is an athlete. He was diagnosed 4 years ago with UC and has done well on SCD diet. He is a healthy weight but in terms of building lean muscle mass and bulking up a little, it is hard on SCD. He has a smoothie every morning with honey, avocado and fruit. On SCD, he can't do traditional protein shakes. Any advice would be appreciated. Daily, he eats cocoa butter cookies, honey bars, other cookies as well.
