If you believe this study that I read about in dailymail.co.uk just drawing comfort food like pizza will cheer you up.
Researchers had college students draw several food items on an empty stomach then looked at their moods and hunger levels afterwards.
They found drawing pizzas improved their mood by 28%, while drawing cupcakes and strawberries raised their moods by 27% and 22%.
Drawing peppers was the only food that decreased their mood by 1%.
They also found that drawing different foods didn't have an impact on their hunger.
