We learn in school that the first step of digestion is in our mouth. When the tongue feels stimulated by the taste of food, it sends a signal to the brain to secrete the right digestive juices and enzymes. This process is essential for assimilation of nutrients and elimination of waste. So you ‘by hearted’ this in school but it didn’t quite touch your heart? Here’s an example.Your grandmom told you that betel leaf is a great source of iron and you scoffed and figured that she comes up with ‘excuses’ to validate her paan addiction. Your child informs you that he will eat spinach today because Popeye says it’s a rich source of iron. You weep and drown in tears of joy. You tweet that kids today are so smart, and so well-informed because of all the ‘exposure’ they receive, blah, blah.
