Food as medicine?

Whether we like it or not but way back in Confucius time he already advocated to eat locally and seasonally cos that is the best for our body and health for optimal absorption of nutrients for your body.Sadly, in today's context, the fast paced society has made us forget our fundamentals and roots such that we have fast food that ain't that healthy anymore. Which is why it is even more important than ever to eat healthier to live longer and happier?
