BKs say that they eat SATVIK FOOD.
Satvik food means fresh, obtained or cooked without any violence or harm to another, and easily digested.
Fried and Spicy food or hot spices like red pepper, ginger, garlic, etc are considered as hot in nature as they increase blood flow and cause digestion problems like hyper-acidity thus termed as Tamsik. Also fermented foods like Dhokla, Bread, Cakes etc. are considered as Tamsik because it is considered as rotten by bacteria or yeast.
Even tea or coffee are also said to be tamsik as it is not a fresh product and have sedative effect due to caffeine.
But now a days a great REFORM is visible in BK HQ. BKs are shifting from Satvik to Tamsik. People visiting there are served caffeine products like tea and coffee. They serve spicy pickles.
Fried Puris and baked breads have been served from a long time ago, Baba forgot to tell them that these are also tamsik ...
Dadis and Didis are fed up now with Rukha-Sukha Bhojan so they cannot control their tastes buds.
I hope we will soon see BKs serving Burgers and Noodles in their HQ ...!!!!
