The diet is usually vegan, but the co-founder of natural hygiene in modern times, one Tilden, encouraged use of non-vegetarian foods. Following high percentage fruit diets is discouraged by most hygienists. However, some who consider themselves to be hygienists, do advocate high fruit diets. There is very wide variation in diet and health practices among hygienists; e.g. disagreements on the use of sprouts, seaweeds, dried fruit, etc. Some otherwise "orthodox" hygienists make occasional use of raw milk/cheese/eggs in their diet.
