The part of the brain most heavily associated with mental health, memory, emotion and mood is called the hippocampus; the biological name for the seahorse. It is the unusual seahorse-like shape of the hippocampus that has led to its evocative name. Just as the seahorse charms the depths of oceans, our own hippocampus, when supported and nurtured, can help to enchant our own lives. Worryingly, there are an increasing number of scientific papers linking problems with the hippocampus to depression, in particular, the shrinking or failure to regrow this part of the brain after prolonged stress. Depression, anxiety and mood disorders are often seen as entirely psychological in cause. However, more and more research is highlighting that chronic health issues, poor diet and lifestyle choices can, and will, negatively impact our vulnerable hippocampus, and consequently, our mental health. Personalised nutritionist Ray Griffiths examines how we can modify our dietary and lifestyle choices to nourish our brain and hippocampus. These choices can help to cushion us from the harm we may encounter as we navigate the challenges of modern everyday life. This nourishment is absolutely vital, as every day our hippocampus can potentially regrow 700 brand new neurons, but it needs a huge amount of assistance to do so. Nourishment for the hippocampus can come from not just diet but also from balanced gut bacteria, social connection, exercise, an outdoors environment, music and dance. Learning how to support your brain health begins with what you eat.
