Your food is not as much harmful as your thoughts.
Your thoughts only keep you in stage of happiness/sorrow pleasure/stressed jealous/content angry/joyous.
One negative/adverse thought can damage your entire metabolism; whatever nutritious food you consume at that state of mind is all waste. So by doing the things which are helpful to make you master of your senses we can attain a good health ,Do Meditation ,Yog,Swadhyay etc.
All these kriyas develop the intellect of choosing the right things .
