In our fast-paced world, maintaining optimal brain health and a robust metabolism often takes a backseat to immediate concerns. Yet, a holistic approach integrating movement and nutrition can significantly enhance our cognitive function and metabolic efficiency. This post delves into how specific foods and activities influence these systems, the role of brain-derived neurotrophic factor (BDNF), the impact on mental health, and the interplay with our genetic makeup.
BDNF, or brain-derived neurotrophic factor, is a protein that plays a critical role in neuroplasticity — the brain’s ability to adapt by forming new neural connections. Higher levels of BDNF are associated with improved memory, learning, and overall cognitive function. Exercise, particularly aerobic activities like running, cycling, or swimming, has been shown to significantly increase BDNF levels. We can also achieve this at moderate or high intensity, meaning benefits can come without over exerting yourself or your adrenals & nervous system… aka, the sweet spot.
Regular physical activity is also a powerful tool in combating depression and anxiety. The increased production of BDNF during exercise helps to mitigate the effects of stress and promotes a sense of well-being. Moreover, exercise induces the release of endorphins, often referred to as “feel-good” hormones, which further enhance mood and reduce symptoms of depression.
Our genetic blueprint plays a role in determining how our bodies respond to physical activity. Certain genetic variations can affect BDNF levels and the overall response of the brain to exercise. While we can’t change our genes, understanding our genetic predispositions can help tailor an exercise regime that maximizes brain health benefits.
For example, being genetically predisposed to low levels of BDNF can set us up for higher rates of depression. And while many anti-depressants work on regulating levels of BDNF, like SSRIs, it’s not that simple. Depression is polygenic, meaning multiple genes contribute, not just one single gene.
Just as physical activity nurtures the brain and metabolism, so too does our diet. The foods we consume can either fuel or hinder our cognitive function and metabolic rate.
Brain-Boosting Foods
Metabolism-Enhancing Foods
As you can see, our genetics and what we eat can significantly influence our mental health. Diets high in processed foods and sugars are linked to an increased risk of depression and anxiety. Conversely, nutrient-dense diets that include fruits, vegetables, lean proteins, and healthy fats can support a balanced mood and mental clarity.
Genetics play a role in our metabolism and how we process different nutrients. For instance, some people may have a genetic predisposition that affects how they metabolize fats or carbohydrates.
You can start today by embracing small changes in your routine such as taking a brisk walk and adding more omega-3-rich foods to your diet. However, getting personalized nutrition and considering one’s genetic makeup, can optimize diet plans for better brain health and metabolic outcomes. And in my 3-month Align program, we do just that!
