I advocate a whole food plant based (WFPB) diet.  

Ultimately how  we  eat  comes  down  to  our  own  habits,  knowledge,  personal  preferences,  values  and  priorities.   From  a  health  point  of  view,  the volume of research that suggests that our diet should predominantly be made up of whole foods and plants is overwhelming and unequivocal.  As stated in this report from the World Health Organisation:

          "Studies of food and health relationships have consistently highlighted associations    between low intakes of plant-based foods as well as high intakes of animal products and ultra-processed foods, and poor health outcomes"

Whether you want to include some fish, meat, dairy or eggs is up to you.    My  own  feeling  is  that  if  definitions  are  going  to  restrict  or  impede  you   from  making  better  choices  it  is  far  better  to  avoid  them.    So  ultimately  it  is  better  to  include  more  plants  in  your  diet  and  not  worry  about  becoming  whole  food  plant  based  than  to  throw  the  baby out  with  the  bathwater  and  not  even  attempt  dietary  improvements.    As  with  every  bit  of  advice  on  this  site  the  governing  principal  is  “ Do  not  let  the  perfect  be  the  enemy  of  the  good”. 

Many  people  chose  to  be  vegan  due  to  animal  welfare  and  environmental  reasons  and  if  this  is  the  case  it  is  useful  to  know  the  enormous added  health  benefits  and  occasional  caveats  to  be  aware  of.  

We believe eating should be a joy.  It should not be about guilt or calorie counting or merely a functional process.  By following certain evidence based principles you can improve your wellbeing, keep a healthy weight and optimise your healthspan.
