In not so ancient history people hired someone to be a sin eater with the belief that special food prepared for the purpose of having the “sin eater” consume it that the sins were consumed through the food and the deceased could ascend to heaven.
Today many believe food prepared by an angry person is unhealthy or toxic which may or may not be true although there is interesting research about the impact on something when negative energy bombards it. Dr Emoto of Japan has done extensive research with profound photographs of water influenced by specific words spoken into it. Words like hate and love significantly change the molecular structure as shown in his book and on his website. If so then it’s worth considering how what you consume may be influenced by specific energy.
The idea of saying a prayer, grace, before a meal can be worth consideration as this usually includes asking the food be blessed.
