Rajma, Idli among Top 25 global dishes causing most damage to biodiversity: Study

Rajma and Idli are responsible for causing biodiversity damage. Here's all that you need to know.

Our favourite food items are causing damage to biodiversity – says a study that was conducted to assess the biodiversity footprints of 151 popular dishes all across the world. The food item with highest damage to biodiversity is lechazo, a roast lamb recipe from Spain. It is closely followed by four beef and meat preparations consumed in Brazil. Idli is ranked sixth in the list, and rajma (kidney beans curry) comes at a close seventh. Dishes containing meat have more biodiversity footprint than vegetarian and vegan dishes, as was expected. However, it was surprising to find Idli – made with rice batter – and rajma – a vegetarian dish – on the list.

Luis Roman Carrasco, Associate Professor of Biological Sciences at the National University of Singapore led the study and said, " The large impacts of legumes and rice in India was a surprise, but when you think about it, it makes sense. In our analysis, the biodiversity footprint represents the number of species that have been at least partially impacted to produce that dish. The biodiversity footprint gives us an idea of how many species we’re pushing closer to extinction by eating that dish."

The study assessed each of the 151 dishes and how the ingredients of the dishes impacted the species richness and range of wild mammals, birds and amphibians in the cropland. Choice of food is influenced by taste, price and health, and the study aims to help people become environmentally conscious by tailoring their food habits.
