In India, where I am from, most of the people sit on the floor to eat their food. It is widely believed that sitting on the floor and eating is more beneficial than sitting in a chair or on a sofa. However there is an exception for light meals and having tea or coffee, most people prefer sitting either on a bed or sofa here also for that.
So, is sitting on the floor a healthier way for people to eat?
The article 10 Reasons Why The Indian Way Of Sitting On The Floor And Eating Is Good For Health lists some of the benefits. I would like to know only about two claims. First the claim on health benefits mentioned in the article, especially "Sitting on the floor helps in digesting food":
When you sit on the floor and bend forward to eat and go back to your natural position. This back and forth movement helps muscles in the abdomen to secrete digestive juices, and helps in digesting the food properly and quickly.
And second the claim about "Humans are not designed to sit in chair" i.e. improving posture:
When we sit on the floor our body posture is automatically corrected with our back straight, expanding our spine and pushing our shoulders back, beating all the frequent pain and aches that are caused due to bad posture.
