Wholefoods are foods that are unprocessed and unrefined, or processed and refined as little as possible, before being consumed. Whole foods typically do not contain added ingredients, such as salt, carbohydrates, or fat. Examples of whole foods include grains, beans, fruits, vegetables and non-homogenized dairy products.Although, originally all human food was whole food, one of the earliest uses of the term post-industrial age was in 1960 when the leading organic food organization the SoilAssociation opened a shop in the name selling organic and whole grain products in London.

The term is often confused with organic food but whole foods are not necessarily organic, nor are organic foods necessarily whole. The United States Food and Drug Administration defines whole grains as cereal grains containing the bran, endosperm and germ of the original grain. Federal Dietary Guidelines issued by the Centre for Nutrition Policy and Promotion in 2005 recommended the consumption of at least three servings of whole grains each day, as there is evidence that they help cut risk of cancer and heart disease.

"Diets rich in whole and unrefined foods, like whole grains, dark green and yellow/orange-fleshed vegetables and fruits, legumes, nuts and seeds, contain high concentrations of antioxidant phenolics, fibers and numerous other phytochemicals that may be protective against chronic diseases."

The modern wholefoods consumer is often a person wishing to take advantage of the health benefits of good food nutrition with an eye to the evironment and reducing their personal footprint in the world; often achieved by combining healthy eating with an ECO ethos ranging from using toiletries containing as few chemicals as possible to buying recylcled consumables such as toilet tissue, to sourcing green energy for the home and the doing without plastic packaging in all its forms.

Wholefoods therefore can be an entire lifestyle choice.
