No, but you can't completely exclude the manipulative effects of communal eating habits. You can't exclude the multi-billion dollar tactics to promote, associate, tempt, entice and feed children, adults and families with fast food.
Nor can you exclude the actual food, including portion size, sugar content, and cost/value from having a "transmission" effect of hooking vulnerable people on convenient, cheap, endlessly available junk food. All repeatedly validated via communal eating habits, symbols, signs and billboard displayed everywhere. Imprints of these messages become part of your brain's neural network over years.
