Some say money buys you happiness, others believe in the power of positive thinking.
Turns out, there could be a cheaper and easier way to put a smile on your face. According to a new study, the answer lies in eating yellow foods.
Research by The Happy Egg Company found consuming yellow food releases significant levels of happy hormones because we associate the colour with feeling joyful, Metro reports.
Psychologists suggest that our positive relationship with colour starts from a young age. Yellow is also said to stimulate the left or logic side of the brain, which encourages us to perceive it as a warm and fun in the spectrum of shades.
The study, which measured the response time of 1,000 people when answering questions about food colours and happiness, found that 70 percent of us link yellow foods with feeling cheerful.
61 percent of those asked said omelettes were the top 'happy' food, followed by the ultimate comfort food, macaroni cheese, with 55 percent of the vote. Bananas, pancakes and poached eggs were also ranked in the top five.
Neuropsychologist Dr David Lewis said he was surprised by the overwhelming response to the colour.
"There is lots of research to show how colour can affect our emotions, but we were surprised to discover that so many yellow food groups evoked such strong positive feelings as well as stimulating taste buds," he explained.
"The research revealed that 30 percent more people associate yellow with happiness than the other colours tested and 62 percent of us want to see more yellow in our fridge."
As for foods that supposedly make us feel blue, the clue is in the name. Stay clear of those pesky blueberries.
