Methods: A non-randomized intervention study was conducted on 70 adults aged 18-70 years responsible for home purchases. Two non-consecutive purchases of food were made in an online supermarket. For each purchase, an amount of money was allocated, the first of CH $ 87,220 (USD $ 134.2) and the second of CH $ 235,400 (USD $ 362.2). The participants were classified according to years of schooling. The purchased foods were transformed into consumption portions. Results: The mean age was 42.1 ± 13.5 years.
