A plant-based diet is a dietary approach that emphasises foods derived from plants, such as fruits, vegetables, whole grains, legumes, nuts, and seeds, while minimising or excluding animal products. This dietary pattern prioritises foods that are rich in nutrients, fiber, and antioxidants, while typically avoiding or limiting the consumption of meat, dairy, eggs, and other animal-derived products.

There can be variations within a plant-based diet. Some individuals may choose to completely eliminate animal products, following a vegan diet, while others may include small amounts of animal products occasionally, following a vegetarian or flexitarian diet. Regardless of the specific approach, the focus remains on plant-derived foods as the foundation of meals and snacks.

Plant-based diets are associated with various health benefits, including reduced risk of chronic diseases such as heart disease, diabetes, and certain cancers. They are also environmentally sustainable, as they tend to have a lower carbon footprint compared to diets high in animal products. Overall, a plant-based diet can contribute to improved health outcomes and environmental sustainability.
