You become what you eat!
A very old saying, that we have listening now and then and keep on ignoring it, but it actually is a great wisdom which warns us that we should be cautious of what we eat because whatever we eat affects us on physical and spiritual levels both.
What do we eat regularly? Grains, pulses, dairy products, and vegetables and fruits. Let us talk about vegetable and fruits here!
We can not imagine our daily food without vegetables and fruits. Food is not just source of energy (as popularly believed now), but they are also essential for proper functioning of our senses and to carry out vital process of continuous renovation of our body. Many cells are built every minute, along with DNA. The building blocks are supplied by foods. Vegetables and fruits supply roughage, fiber, carbohydrate, proteins, various trace elements (zinc, potassium, iron, phosphorus etc.) along with various essential Vitamins.
History of thousands of years of human migration tells us that homo sapiens have always been in search of better locations for living their lives. Better in terms of food security, ecology, law and order etc. The process of migration which began 70,000 years ago, when homo sapiens moved out of Africa, continued for 40000 years. History notices it as first wave of migration.
History has observed several such waves of migration.
Urbanization can also be seen as one of the waves which began in England during Industrial Revolution of Britain and is still hitting the shores of various countries across the world.
