Definition of health food

The term "health food" emerged in the late 19th century, coinciding with growing interest in natural living and preventative medicine. It was popularized in the early 20th century, fueled by the rise of the "health food" movement, which emphasized whole, unprocessed foods and avoiding artificial ingredients. This movement was influenced by various factors, including the rise of vegetarianism, concerns about food adulteration, and the popularity of alternative medicine practices like naturopathy. "Health food" initially referred to specific food groups like grains, fruits, and vegetables, later broadening to encompass a wider range of products marketed for their health benefits.
