Replacing red meat with chickpeas & lentils good for the wallet, climate, and health
Systematic review: This type of study is a structured approach to reviewing all the evidence to answer a specific question. It can include a meta-analysis which is a statistical method of combining the data from multiple studies to get an overall result.
Simulation/modelling: This type of study uses a computer simulation or mathematical model to predict an outcome. The original values put into the model may have come from real-world measurements (eg: past spread of a disease used to model its future spread).
People: This is a study based on research using people.
New Zealand researchers investigated five diets which replace some or all red meat, finding they all could provide the recommended amount of nutrition, save the health system thousands of dollars per person, and cut diet-related greenhouse gas emissions by as much as 35%. The greatest benefits for all of the above were seen for a diet which replaces all meat with minimally-processed plant-based alternatives such as legumes - which also had a 7% lower average grocery cost.
