Thank you so much Khun SR. Feeling of happiness is one important dimension linked into our emotional brain where is working on an eating center. So, this good feeling will be sensed into the motor cortex in the brain which later functioned on our physical (sensori-motor skills) in relation with happiness such as physical exercise, cognitive exercise, and social participation. Also, I do agree with you regarding the micro- & macro environment related happiness from optimal nutirtions and cooking processes.
