What is serotonin?

Serotonin is a neurotransmitter which is widely associated with feelings of happiness and well-being, although it does have other wide-ranging biological functions. It’s a molecule produced in order to regulate communication among other neurons in our brains. 

To feel happy, our brains rely on a wide range of similar hormones, including serotonin. Other examples are endorphins, which are like a natural form of morphine, and oxytocin, which is the hormone linked to affection and security. The interesting thing about serotonin and other wellbeing hormones is that we are able to stimulate their production by controlling our lifestyle, hygiene and food consumption. 

Nutrition is one of the keys to achieving serotonin nirvana. Banana-based smoothies, for example, are rich in vitamin B, magnesium and tryptophan, while avocado based ones are rich in stress-reducing tyrosine.

You can also sprinkle pumpkin, chia and sesame seeds on your salad for a boost in zinc and Omega 3. So long live sardines, bluefin tuna and halibut, all rich in essential fatty acids, which the body isn’t able to produce on its own. These help raise serotonin and melatonin levels.

And don’t forget tryptophan, an amino acid which is a precursor to serotonin. It’s present in chicken, fish and legumes like split peas, lentils and dried beans.

Fermented ingredients also do wonders for our intestines, which are like a “second brain” lined with neurotransmitters, as outlined by Dr Michael Gershon in his book of the same name. We’re talking the likes of pickles, fermented cabbage and yoghurt, which can have a positive effect if eaten three times a week.
