* No one won an Oscar for "eating Gilbert Grape."
There was no category for eating in the Academy Awards!
Perhaps you're thinking of Leonardo DiCaprio, who was nominated for Best Supporting Actor for his role as Arnie Grape in the movie "What's Eating Gilbert Grape?" (not "eating Gilbert Grape").
He didn't win the Oscar that year, but it was his breakout role and a critical acclaim that helped launch his career.
Let me know if you have any other movie-related questions! 😊
