Personally I don't give a poo. But I do avoid marge, only use cold pressed olive oil, have given up high dose vitamin suppliments, and nolonger live in the city.
As someone gave tribute:
I would also like to mention Adelle Davis the highly-respected american nutritionist who, despite forbidding roasting frying & grilling (because of carcinogens) and recommending that all food should be boiled in her book Let's Cook It Right, still died of cancer.
I also fondly remember another american with the answer to everything, Jim Fix the jogging guru, who forecast that (by jogging) he would live to to the age of 140. Unfortunately he dropped dead at the age of 50 from a heart attack while out running.
