It is high in salt, sugar, and fat and relies heavily on animal products. This diet requires significant water and land resources to produce and leads to greenhouse gas emissions. It increases the risks of diseases like diabetes, heart disease, obesity, and hypertension. The document suggests promoting more sustainable food production and consumption, including lowering meat consumption, as a solution to reduce these environmental impacts and health risks.
