The chart below follows the previous post encouraging folks to eat more deeply-colored vegetables and fruits for health.
It summarizes the main classes of plant pigments (light-harvesting molecules that plants manufacture), the roles they play in plant health, the foods rich in each pigment class, and its potential value to human health.
Bon appetit!

Roles in plants |
Foods rich in these pigments |
Potential value to humans
|
| Chlorophyll (fat-soluble) | green | harvest light; initiate photosynthesis | green vegetables | help deactivate carcinogens |
| Carotenoids (fat-soluble: eat with a little fat) | red-orange-yellow | attract pollinators and seed dispersers
accessory photosynthetic pigment in periods of low light, absorbs excess light energy, antioxidant roles, substrate for hormones |
carrot, sweet potato, winter squash, pumpkin, green leafy vegetables, cantaloupe, apricot | protect immune system, skin and epithelial cells, prevent heart disease, cancer, macular degeneration |
| Anthocyanins (water-soluble: don’t throw out cooking water) | blue-purple-burgundy- | attract pollinators and seed dispersers
repel predators, protect cells from damage by excess light, improve plant tolerance to stress such as drought, UV-B, and heavy metals, resist disease, scavenge free radicals. |
purple vegetables (onions, cabbage, potatoes), red, blue & purple berries, black beans | prevent, forestall, possibly even reverse age-related cognitive declines and neuro-degenerative diseases; improve night vision and other vision disorders, protect against heart disease, insulin resistance, cancer; promote wound healing |
| Betalains (water-soluble, never co-occur with anthocyanins) | red, yellow | powerful antioxidant | beets (red and yellow), chard, spinach, fruit of prickly-pear cactus | antioxidant, may protect against heart disease, various cancers, ulcers, liver damage |
