Plant-based diets involve consuming primarily or exclusively foods that come from plants, such as fruits, vegetables, grains, nuts, seeds, and legumes. These diets typically exclude or minimize the consumption of animal products, including meat, dairy, and eggs. Plant-based diets have been associated with numerous health benefits, including reduced risk of chronic diseases like heart disease, diabetes, and certain types of cancer. Additionally, plant-based diets are often more sustainable and environmentally friendly than diets high in animal products. There are various types of plant-based diets, including vegetarian, vegan, and flexitarian, each with different levels of restriction in terms of animal product consumption. Research in this area focuses on the health effects, environmental impact, and sustainability of plant-based diets, as well as strategies for promoting and adopting plant-based eating patterns.
