Not food culture but if possible, change thought culture. Long back, I was listening to a Swamiji. From that long preaching among others, this sentence stays. He said-Whatever we eat sweet or saltish food during the day, the next morning when it comes out the smell is almost the same. Jesus Christ said: “That which goeth in defileth not a man, but that which cometh out- Covetousness(greed), wickedness, deceit, lasciviousness(lust), pride" Whatever may be the position in the religious or social pyramid, it is important that not only in our words, thoughts, and body language but in our actions also there is no room for greed, wickedness, deceit, lust, and pride. We can not change others but we sure can change ourselves.
