In daily diets, the color of vegetables often hides nutritional codes. The core nutritional differences between dark-colored and light-colored vegetables lie in their nutrient density and antioxidant content. Dark-colored vegetables generally refer to varieties with rich hues such as deep green, red-orange, and purple-black, such as spinach, broccoli, tomatoes, and red cabbage, whose nutrient density is far higher than that of light-colored vegetables. Rich in natural pigments like chlorophyll, beta-carotene, and anthocyanins, these vegetables serve as "concentrated sources" of antioxidants, effectively eliminating free radicals in the body and reducing the risk of chronic diseases.

In terms of nutrient content, dark-colored vegetables have obvious advantages in vitamins and minerals. The beta-carotene content in spinach is 24 times that of Chinese cabbage, and its vitamin K content is 20 times that of iceberg lettuce. The content of minerals such as calcium and iron is also 1 to 5 times higher than that of light-colored vegetables. Meanwhile, dark-colored vegetables have a high proportion of insoluble dietary fiber, which enhances satiety, promotes intestinal peristalsis, and regulates blood sugar and lipids. Light-colored vegetables like Chinese cabbage, winter melon, and lettuce, though abundant in water and refreshing in taste, have relatively low overall nutrient concentration except for some with characteristic components, making them more suitable as a basic match in the diet. Following dietary guidelines, dark-colored vegetables should account for more than half of daily vegetable intake to obtain nutrients more efficiently.
