Our eating habits have a significant impact on personal health and global environmental concerns. About a third of human-caused greenhouse gas emissions come from food production, directly linking our diets to health problems such as obesity and heart disease. The Paris Agreement highlights the urgent need to change our eating habits. Adopting diets that emphasize fruits, vegetables, and legumes while limiting red and processed meats can minimize carbon emissions and promote better health. However, the abundance and complexity of available food choices makes changing habits challenging. Promoting simple dietary substitutions, such as choosing poultry over beef, may be a more feasible and effective solution than drastic changes like becoming vegetarian. Given the complexity of food choices and the challenges associated with changing dietary habits, further research is crucial to identify simple dietary alternatives that can benefit both the environment and human health in diverse populations.
