Well why do i eat salad? Why do i drink water? Why do i chew gum?...... Shouldnt i just stick to eating Mcdonalds 5 days a week, drinking soda and eating pasta, bread and potatoe topped with ketchup and cheese everyday and also muffins, crisps and chocolate.... Just to prove im healthy?
When you are recovered both physically and mentally you can make choices.... just like a normal person. You can choose to drink normal coke or diet coke, to drink water or a lemonade, buy sugar or stevia. The choice is there.... But healthy is also NOT being afraid of the other option.
Do you choose to eat whole grain pasta 6/7 times and white pasta now and again. Thats fine, that doesnt make you sick. Its a persons behaviour and thoughts.
