7 Health Benefits and 6 Risks of Eating Bananas
Risk 2: Drowsiness
Bananas contain tryptophan, an essential amino acid that is known for its ability to promote sleep. Because the carbohydrates in bananas also prevent the influx of amino acids into the brain, this function stimulates the production of serotonin in the brain, which also leads to drowsiness.
Magnesium also has the effect of relaxing muscles, so eating too many bananas can lead to drowsiness.
