What is food all about?
Will rules be of any help? Yes and No.
It has to deal with your taste rather than the rules you might have been cramming for long now. If tast does not lead you to healthy food, develop a taste. Taste health. It is not so difficult to find your 'tasty' food as you are now at a place that is so natural, full of greenery and clean air, to nourish you and your senses.
Rules may be broken by the drive of taste. This you have seen but desire for health brings you back to rules and then your taste pulls you away. So, invite taste. Love your taste. With it also cultivate your taste. Have a taste that will help you nourish your body, mind and soul.
