All about fruitarianism with a long-term fruitarian, Lena

William T. Jarvis, former professor of public health, founder of the National Council against Health Fraud (www.ncahf.org):

“Enzymes are complex protein molecules produced by living organisms exclusively for their own use in promoting chemical reactions. Orally ingested enzymes are digested in the stomach and have no enzymatic activity in the eater.” 

Andrea Giancoli, R.D., a spokesperson for the American Dietetic Association:

Enzymes are proteins and proteins denature with heat, but those enzymes are denatured - and thus inactivated - when they reach our stomachs. Our stomach acids are designed to break down proteins very efficiently.”

Jeremy Bentham

The question is not, "Can they reason?" nor, "Can they talk?" but "Can they suffer?” 

Nutrient-Dense Food

Nutrient-dense foods are foods that have a lot of nutrients but relatively few calories.

Nutrient-dense foods and beverages contain: vitamins, minerals, dietary fiber, and other beneficial substances that may have positive health effects.

They are also naturally lean or low in saturated fat, and have little or no added saturated fat, sugars, refined starches, and sodium.

Examples of nutrient dense foods are: beans and peas, fresh fruit, unsalted nuts and seeds, vegetables, whole grains - most fruitarian foods are nutrient-dense.
