What is a ‘plant-based’ diet?


‘‘A plant-based diet, generally, focuses on the primary consumption of foods derived from plants (fruits, vegetables, nuts, seeds, legumes and whole grains). But it can also include small amounts of foods of animal origin – dairy, eggs, meat and fish. Therefore, the term “plant-based diet” is quite broad in its connotation.’’


‘‘Plant-based diets constitute a diverse range of dietary patterns that emphasize foods derived from plant sources coupled with lower consumption or exclusion of animal products. Vegetarian diets form a subset of plant-based diets, which may exclude the consumption of some or all forms of animal foods’’.

  • Plant-based diets are gaining popularity due to a variety of reasons e.g., health, environmental concerns, animal welfare issues and religious beliefs. 
  • The global retail sales for plant-based foods (primarily those of plant-based meat and dairy alternatives) are expected to reach USD 162 billion by 2030, up from USD 29.4 billion in 2020.
