4. Bananas

Bananas are an excellent source of B vitamins, needed to increase energy production and to dampen your stress levels. Bananas also contain tryptophan, an amino acid needed for serotonin production, our ‘feel good’ hormones. Bananas are also packed with potassium, used to produce sex hormones, and improve heart health and sex drive. Bananas also contain an enzyme called bromelain, which helps improve blood flow and increase libido.
