i have an autoimmune skin disease called seborrheic dermatitis and in order to heal it i have to eat super-healthy (i am a whole food-plant based eater) and i must look at every ingredient in packaged foods,detergents,toothpastes,soaps etc.my progress towards healing dermatitis has stopped & has gotten a little worse and i believe one of the reasons could be some of the ingredients in the mastic gum that i chew so i've stopped chewing it.my question is if i stop chewing gum how many hard foods per day should i eat in order to build good muscle tone?i currently eat fibrous foods like 1-2 oranges,1 green apple,1-2 hard vegetables and a handful of pumpkin seeds every day.is it enough?
