Consuming a variety of colors in fruits and vegetables is primarily beneficial because different colors often indicate the presence of different vitamins, minerals, and antioxidants. Each color represents specific phytonutrients that contribute to health in unique ways. For instance, orange and yellow fruits and vegetables are typically high in vitamin C and carotenoids, while green ones tend to be rich in vitamins A, C, and K, along with fiber and folate. Red fruits and vegetables often contain lycopene, which is associated with several health benefits, including reducing the risk of certain cancers. Therefore, a colorful diet ensures a more comprehensive intake of essential nutrients and protective compounds that can support immune function, reduce inflammation, and promote overall health.

While increasing fiber intake and macronutrient balance are valid considerations within a nutritious diet, the primary advantage of eating a wide array of colorful produce is the enhanced intake of vitamins and antioxidants that contribute to overall health and well-being. Maximizing caloric intake is typically not a goal when focusing on the nutritional benefits of fruits and vegetables; rather, the emphasis is on obtaining health-promoting compounds without excessive calories.
