Milk is an essential food source for us but it was not until 2001 when the Food and Agriculture Organisation of the UN came up with a day dedicate to this nutrient rich liquid. June 1 is celebrated each year as World Milk Day in order to recognise the importance of milk and its various by-products. The day is marked to recognize the power of milk as a global food which plays an important part in our diets as well as a source of income for millions around the world. Several countries across continents hold events discussing the importance of milk. Farmers, politicians, nutritionists, academics raise glass of milk in show of solidarity.
