hello,
from a scientific point of view, it is true that sharing food with others or between families encourages us to consume more and eat healthily.
Because we remember the meal when we talk and share a good time. therefore, for the same meal, just having other people at your table could help increase your hunger.
The fact of exchanging words around a food would make it possible to create social or family ties and to exercise your brainpower and above all it would make it possible to feel less alone.
And therefore less inclined to have lower morale.
