Sustainability is a complex topic in which the food production system and our eating habits play critical roles. Achieving a healthy and sustainable food future is a pressing issue that will require worldwide cooperation. A sustainable diet is one that is generally healthy while also having a low environmental and food-supply effect. Adopting a sustainable diet can help people retain their health while also ensuring the planet's resources are available to feed future generations of humanity. This is a complicated concept, but in its most basic form, a sustainable diet appears to benefit both the individual and the ecosystem, both now and in the future. Diets with low environmental impacts that contribute to food and nutrition security as well as a healthy life for current and future generations are known as sustainable diets. Sustainable diets are biodiversity and ecosystem-friendly, culturally acceptable, accessible, economically equitable, and inexpensive, nutritionally adequate, safe, and healthful, and they maximise natural and human resources.
