i know what you mean about the old looking health nuts, because that is one thing that discouraged my mom's friend from eating healthy, she saw what it did to her relatives, they got illnesses and died young. i believe that health nits often do not really know what is healthy sometimes. for instance, health nuts who eat lots of grains think they are eating right and most grains (not rice) are bad for you. dr mercola even wrote the book, the no grain diet. i don't agree with everything in it because it was based on the glycemic index and not the glycemic load (he gets very restrictive on fruits and vegetables), but still it has a good message. and many health nuts are vegetarians and mercola and some others say that will make you ill. so, i think you have to really look at the individual and what they are eating and using to see if they are in fact doing things truly healthy.
