We implemented a market basket survey of F&V from December 2018 to February 2019 in middle-income neighborhoods of the following cities: Visakhapatnam, India; Kathmandu, Nepal; Addis Ababa, Ethiopia; Dar es Salaam, Tanzania; Mexico City; Bangkok, Thailand; and Brookline, USA. The total variety of fruits ranged from 4.1 in Visakhapatnam to 17.3 in Brookline, and vegetables from 6.1 in Dar es Salaam to 20.3 in Brookline. Of the three fruits for which price data were collected, apples tended to be the most expensive, and bananas the least expensive. For vegetables, capsicum tended to be the most expensive and eggplants the least expensive. Tablet-based market basket surveys are a useful tool for evaluating food environments. These pilot data provide further evidence of the homogenization of global diets.

A cartoon schematic of the steam annealing apparatus, consisting of a tube furnace equipped with a water vaporizer (connected by Al tubing heated at ~70 °C) and a removable sample heating stage. The tube furnace was kept at 125 °C, while the sample stage was ramped up to the desired annealing temperature (rate = 25 °C min-1). The water vapor content was kept constant with a flow rate of ~5.3 mL min-1 .
