Bananas contain the amino acid tryptophan as well as vitamins A, B6 and C, fibre, potassium, phosphorous, iron and carbohydrate. Mood-boosting carbohydrates aid in the absorption of tryptophan in the brain, while vitamin B6 helps convert the tryptophan into the mood-lifting hormone serotonin.
This helps to boost your mood and also helps you sleep. Because of its ability to raise serotonin levels, tryptophan has been used in the treatment of a variety of conditions, such as anxiety, depression and insomnia.
Eat a banana as a mid-morning snack each day or slice it into porridge in the morning.
