Mumbai: In 2015, the term ‘planetary health’ was introduced to emphasise the critical role of natural systems in supporting human health and survival. The Planetary Health Diet (PHD) extends this concept by connecting dietary choices to long-term human health and the sustainability of the Earth. Its primary objective is to promote a sustainable food system that provides nutritious food for a growing global population.

The planetary diet serves as a worldwide standard for adults, visually depicted as half a plate of fruits and vegetables and the other half includes mainly whole grains, plant-based proteins like beans, lentils, and nuts, unsaturated plant oils, moderate amounts of meat and dairy, and some added sugars and starchy vegetables. This diet is adaptable to individual dietary requirements, preferences, and cultural practices. Choosing vegetarian or vegan variations within the planetary health diet is a matter of personal choice which are considered healthy options. Planetary diet benefits

The Planetary Health Diet (PHD) is characterised as a flexitarian eating pattern that emphasises a predominantly plant-based approach with the occasional inclusion of fish, meat, and dairy in modest quantities.

It promotes diversity in vegetable and fruit consumption by advocating for a variety of colours. The diet prioritises unsaturated fats over saturated fats and restricts the intake of refined grains, heavily processed foods, added sugars, and starchy vegetables (such as potatoes).

It aims to provide an appropriate caloric intake, typically around 2500 kcal per day for an average adult, adjusting according to individual factors like age, gender, and activity levels.

There is extensive evidence supporting the health advantages of incorporating more plant-based foods into your diet. The increased fibre content in plants promotes gut health and serves as a vital energy source for gut microbes. Furthermore, following the PHD’s recommendations of lower sugar and refined carbohydrate intake could potentially lower the risk of metabolic conditions like type 2 diabetes and heart disease.
