What is a defining characteristic of "whole foods"?

Whole foods are characterized primarily by being minimally processed and containing no artificial ingredients. This means that whole foods retain most of their natural nutrients and integrity, making them closer to their original state. When foods are minimally processed, they undergo little to no alteration from their natural form which enhances their nutritional value and health benefits. Whole foods include items like fruits, vegetables, whole grains, nuts, and seeds—these foods not only provide essential vitamins and minerals but also support overall well-being without the addition of preservatives, excessive sugars, or unhealthy fats.

The focus on whole foods is significant in nutrition because they can contribute to better health outcomes, weight management, and improved dietary patterns. This characteristic directly aligns with contemporary dietary guidelines that encourage the consumption of whole foods as part of a balanced diet. Thus, the principle of whole foods being free from artificial ingredients emphasizes their role in promoting natural nutrition and health.
