Our body gets the energy for it to live and thrive from food and as every cell in our body, our brain and nerves are affected too. Our brain needs a set of nutrients regularly to function well since it is built up from oxygen, water, fatty acids and many other nutrients. It is impressing that a change in our diet can cause changes in mood, cognitive functioning, energy and even behaviour and has a potential to lessen mental health problems. Eating is a thing that we need to do daily anyway so why not to use it?
