Explanation
In France, eating with the left hand is not inherently rude, as both hands are typically used at the table (fork in left, knife in right). However, using the left hand alone to bring food to your mouth may be seen as awkward or less refined in formal dining settings, where the fork is traditionally held in the left hand and the knife in the right.
Local Tip
Keep your fork in your left hand and knife in your right when cutting food, and avoid switching hands to eat with your left hand alone.
How it compares elsewhere
The left hand is considered unclean and used for hygiene; always eat with the right hand.
Eating with the left hand is taboo, especially when sharing communal dishes.
Both hands are acceptable, but chopsticks are the norm; left-hand use is not stigmatized.
