Spinach
So much goodness is packed into this leafy green including tryptophan and folate. Serotonin is a neurotransmitter that floats around our brain and helps us feel happy. The tryptophan found in spinach helps increase our levels of serotonin, so we can turn that frown upside down. Spinach is also high in folate, another nutrient that helps increase levels of serotonin in the brain. Next week, we’ll be eating a TON of spinach in things like pesto, salads and smoothies!
