Brain derived neurotrophic factor (BDNF) is sadly not an Instagram favourite or a premier influencer on social media, which is regrettable, as it is one of the principal conductors of our higher centres stimulating the production of new brain cells and enhancing the connectivity between these cells, making it possible for us to learn anew and consolidating the memory of these novel principles. Emotional resilience, the ability to repair and regenerate damaged brain cells and neuroplasticity all depend on the function of this orchestrating protein. Conversely producing less BDNF as we age can lead to diminished memory and cognitive decline suggesting that doing all we can to preserve this precious resource might help to decelerate brain ageing.
There are a host of ways by which BDNF can be ignited. A high protein diet, intermittent fasting or eating less, all not easy to maintain especially as we get older, augment BDNF. Good old exercise, both resistance training and aerobic activity, together with yoga are BDNF promoters. Zinc deserves a special mention as it is the one nutrient shown in trials on humans to stimulate BDNF production.
