My approach, driven by scientific research in macro-biology, is to consume as much food as i can, of as many different types as i can.
My digestive system is trained to filter out the good stuff and sends it round my body, to my organs, bones and skin, whilst simultaneously sending the bad stuff + the waste to my A***Hole.
It a mightily impressive system that i have been using for as long back as i can remember. I get a reminder signal in my stomach when more food needs to be ingested into my eco-processing unit.
