Did you know that the same compounds responsible for the color of your vegetables are also nutrients? This is why you will often hear me say that “eating the rainbow” is a very valid strategy to help achieve nutrient sufficiency!
For example, the vegetables richest in carotenoids (like α- and β-carotene) include anything red, orange, yellow, or dark green, which includes carrots, beets, squash, sweet potatoes, kale, spinach, collard greens, and broccoli.
Red vegetables, like tomatoes, radicchio and radishes, are also rich in lycopene and anthocyanins (or betalains, in the case of beets – fun fact, anthocyanins and betalains, both deep red pigmented phytonutrients, are never found in the same food!). Anthocyanins can also be found in vegetables with blue and purple colors, as can anthocyanidins, including purple varieties of cauliflower, kale, carrots and purple sweet potatoes.
Orange and yellow vegetables are also rich in β-cryptoxanthin. Yellow vegetables are additionally rich in xanthophylls. Green veggies provide chlorophyll, glucosinolates, lutein, and zeaxanthin.
And don’t think that white veggies, like mushrooms, turnips and white onions, are devoid of these beneficial phytonutrients; they are rich sources of anthoxanthins and organosulfur compounds.
These phytonutrients have antioxidant and anti-inflammatory properties, in addition to many of them also having anticancer, cardioprotective, hepatoprotective and neuroprotective properties! In fact, these amazing pigment phytonutrients are largely responsible for the health benefits of a diet abounding in veggies and fruits. In fact, for every serving of fresh, whole vegetables or fruit we eat daily, risk of all-cause mortality (a measurement of overall health and longevity) reduces by 5% to 8%.
