Whole foods

Whole foods 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 sugar, salt, vitamins, or fat.
Examples of whole foods include unpolished grains, beans, fruits, vegetables and non-homogenized diary 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 called the Soil Association open a shop in the name selling organic and whole grain products in London, UK.
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 Center 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."
