Green beans are totally underrated. They’re not just some random side dish; these little green legends are nutrient-packed superstars. Plus, they make any plate look 10 times more Insta-worthy with their vibrant colour and fresh vibes.
In a Health For Mzansi article, Hamond Motsi, an agronomist and PhD student at Stellenbosch University, highlights the value of green beans’ antioxidant content, including flavonols, quercetin, and kaempferol.
“These antioxidants act as protective agents against harmful free radicals and reactive oxygen species – factors that contribute to ageing and various health issues,” Motsi explains.
Beyond their antioxidant properties, green beans are high in fibre and contain no cholesterol, making them an excellent choice for anyone on a weight-loss journey. Their natural sugars and protein content also make them suitable for people living with diabetes. But to unlock these benefits, the growing conditions play a critical role.
“Adverse conditions such as water scarcity, temperature extremes, and soil nutrient deficiencies can result in lower concentrations of vital vitamins and minerals in the harvested beans,” says Motsi.

Preparing the ideal soil for green beans
Creating the perfect environment for green beans starts with well-drained, fertile soil. Lulutho Gangathele, a farmer and agronomist from the Eastern Cape, advises using sandy loam soil enriched with compost or fertiliser and maintaining a pH of 6.0 to 6.5.
“Avoid planting in soils with large clods, as this can negatively impact seed emergence,” Gangathele warns.
Temperature is equally crucial. Green beans thrive in temperatures between 16°C and 24°C and are highly sensitive to frost and extreme heat. To ensure a healthy harvest, Gangathele recommends careful pest and disease management, including crop rotation and using natural remedies like soapy water mixtures for aphid control.
When harvested young and tender, green beans deliver maximum nutritional value. “Allowing green beans to become overly mature results in a tough texture and unpleasant taste, potentially leading to a decrease in nutrients and reduced health advantages,” Motsi says.
Whether you’re growing them in your backyard or on a commercial scale, green beans are a worthy addition to any farm or kitchen, bringing both flavour and wellness to the table.
