A feeling of heaviness or bloating after a meal maybe an indication that you are intolerant or even allergic to certain grains i.e. mostly wheat but even rice. Introduction of genetically modified strains in the market maybe the primary cause of wheat intolerance and allergies in the Indian populace. Fortunately some excellent alternatives are available like Bajra or Jowar or Ragi or Sattu. Health is a factor of what you eat so make your choices carefully.
