discriminating food?

Festivities are amidst in India these days with the festival of Navratri being celebrated for 9 consecutive days and ending with Dussehra being the grand finally on the 10th day. Though I do not live in India, I do see the energy, excitement, and colourfulness in photos posted on social media. People getting together to celebrate the themes of purity and power and offering each other prasad (religious food offering) in the form of blessing from God.

But one thing I fail to understand today is why is only prasad considered a blessing from God? Why do we give it more value than what we eat on a daily basis? Why do we treat it with more respect and cherish it to no end?

Is it because we are incapable of doing so everyday, 3 times a day?
