Context

Unhealthy and unsustainable diets are common worldwide. Health and sustainability need to be balanced because environmentally sustainable diets may lack macro- and/or micronutrients, resulting in nutrient deficiencies.

Objective

A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to analyze the environmental impact of current diets and alternative dietary scenarios worldwide based on food-group consumption.

Data sources

The Scopus, Web of Sciences, and PubMed literature databases were searched. Only studies quantifying the food composition of diets per food group and their environmental impact were eligible.

Data extraction

Data were extracted for food groups as averages, means, or me
