Many nutrients in vegetables are important for your brain and nervous system to function well.
Some of the most significant ones include B-group vitamins (biotin, folate, niacin, pantothenic acid, riboflavin and vitamin B6), vitamin C, and minerals such as calcium, iron and potassium.
These vitamins and minerals are involved in the synthesis of neurotransmitters (signalling molecules) and maintenance of cognitive function. They also help you to stay alert by reducing tiredness and fatigue.
Throw your veg in the pan soon after chopping them up to avoid losing all the good stuff in them. Vegetables can lose nutrients once exposed to light and air.
