Green is the new orange: Why carrot leaves shouldn’t be thrown away

The call to reduce food waste has grown louder in the time of climate change. One of the obvious yet overlooked examples of wasted food potential is the carrot (Daucus carota).

When we think about carrots, we only remember the colourful roots of its various varieties. The red ones are grated and cooked in milk to prepare a halwa or gajrela, while purple carrots are used to make a tangy fermented drink called kanji in Uttar Pradesh.

But roots do not capture the full magic of the carrot. The lacy green leaves make up nearly half of the weight of the vegetable but rarely reach the markets or our plates.

They are often discarded after harvest to improve the shelf life of the roots, and merely used as animal and poultry feed. But they have potential to increase food diversity for human beings, not to mention their huge nutritional value.

Carrot leaves, just like the roots, are rich in vitamin A. Carbohydrates and protein account for 60 per cent and 20 per cent respectively of the leaves’ dry weight, as per a study published in the Journal of Food and Dairy Sciences in April 2011. The leaves have potassium that lowers blood pressure, supports metabolism and prevents osteoporosis.

They also contain calcium, phosphorus, iron and zinc. Given that they are rich in natural antioxidants, carrot-green extracts are often added to commercial food products. No wonder health food enthusiasts and foragers use them in herbal teas, soups and salads.

Carrot seeds too have medicinal value: they contain estrogen and were used in some cultures as an effective method of contraception. Lebanese folklore mentions the use of carrot seed oil from wild plants in cancer treatment — modern research proves this. The oil also has anti-ageing properties and features in skin-care products. 

Familiar flavour 

Scientists believe carrots were domesticated 1,000 years ago. Russian botanist Nikolai Vavilov, who traced carrots’ origin to be near Afghanistan in Central Asia, postulated sometime in the 1920s that the domesticated variety of the vegetable can be divided into Eastern and Western groups (depending on the side of Afghanistan they grew).

The Eastern group has anthocyanin-pigmented roots which are purple, pink or orangish-yellow. Carrots in the Western group have carotenoid-pigmented roots that are yellow, orange or red — and occasionally white. The two groups also differ in taste; the Western group is sweeter. But their leaves taste the same — an earthy flavour reminiscent of the root with a spicy aftertaste, à la mustard leaves.

Perhaps this familiarity of taste is why, despite not being commonly sold in markets, the leaves are used as a common green in several cuisines. In Japan, for instance, the leaves are stir-fried with soya sauce. In several European countries, they are part of salads and soups.
