Sustainable practices for healthy meal preparation include using locally sourced ingredients, minimizing food waste, and choosing plant-based options. Incorporating seasonal produce not only supports local economies but also ensures freshness and nutritional value. Batch-cooking can reduce time spent in the kitchen while decreasing food waste by making use of leftovers. By planning meals ahead and opting for less packaging, individuals can further promote an environmentally friendly approach to eating, fostering sustainable food practices that benefit personal health and the planet.
