What do different colors of fruits and vegetables mean?

Blue/Purple– This color is due to the fruit’s or vegetable’s anthocyanin content. Anthocyanins are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In alkaline conditions, it appears in blue/purple or black color. The darker the blue color, the higher the concentration of phytochemicals in it.

Anthocyanins are antioxidants that provide numerous health benefits. They also protect against UV skin damage by inactivating highly reactive molecules such as free radicals and reactive oxygen species (ROS) formed during sun exposure that start a chain reaction producing significant cell and tissue damage. Recent research also suggests that anthocyanins may help fend off major health problems, including heart disease and cancer.

Blueberries are especially known for their very high antioxidant levels. Other fruits and vegetables containing Anthocyanins include pomegranates, blackberries, plums, prunes, red cabbage, etc. Apart from that Beetroot’s deep purple color comes from plant chemicals called betanins. Like anthocyanins, betanins have antioxidant and anti-inflammatory properties.

Green– Green leafy vegetables are rich in chlorophyll as well as isothiocyanates. Chlorophyll can be found in each and every green plant part. Isothiocyanate is the chemical group –N=C=S, formed by substituting the oxygen in the isocyanate group with sulfur.

The potential benefits of chlorophyll include improving health, boosting energy, and fighting illnesses. When considered isothiocyanate, it neutralizes toxins especially in the liver, and can potentially contribute to the prevention of cancer. Apart from these antioxidants, the green cruciferous vegetables are rich in Vitamin K, folic acid, potassium, etc. which help to keep the body functions well.

It is especially necessary for elderly people to prevent age-related macular degeneration. Broccoli, spinach, kale, corn, orange pepper, kiwi fruit, grapes, oranges, zucchini, and squash are some fruits and vegetables rich in lutein.

Some of these green-yellow fruits and vegetables are also rich in vitamin C also known as ascorbic acid which is necessary for the growth, development, and repair of all body tissues.

Red– The main pigment that gives the red color to fruits and vegetables is Lycopene. Lycopene is a powerful antioxidant with many health benefits, including sun protection, improved heart health, and a lower risk of certain types of cancer. Though it can be found as a supplement, it may be most effective when consumed from lycopene-rich foods like tomatoes and other red or pink fruits. Grapes, cranberries, tomatoes, watermelons, guava, pink grapefruit can be taken as examples. Red fruits and vegetables are also rich in flavonoids, resveratrol, and vitamin C as well as folates specially beetroots.

Orange– Carotenoids or beta carotene is responsible for imparting the yellow-orange-red pigment color to certain fruits and vegetables.
