Switching to a vegan diet could lower food costs by 19%, while switching to a Mediterranean diet is unlikely to have an impact on the cost of groceries, according to a US study. The study compared 30 people who started a vegan diet and 30 people who started a Mediterranean diet and estimated their food costs based on several three-day records of what they ate during the study. The researchers say the lower costs of the vegan diet were mainly associated with savings on meat and added fats, and these savings outweighed the increased spending on vegetables, grains and meat alternatives.
