Going vegan could help cut your food costs by almost 20%
Randomised controlled trial: Subjects are randomly assigned to a test group, which receives the treatment, or a control group, which commonly receives a placebo. In 'blind' trials, participants do not know which group they are in; in ‘double blind’ trials, the experimenters do not know either. Blinding trials helps removes bias.
People: This is a study based on research using people.
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.
