This trailblazing resource bridges the divides between nutrition, dietary patterns, hormones, and psychological wellbeing. It's interdisciplinary and integrated approach to human health provides a more holistic understanding on how to achieve systemic balance. The extent to which contemporary food environments impact metabolic, neurological and emotional processes is comprehensively explored, alongside the potential of functional medicine, nutritional science, and neurobiology to encourage better mental and physical health outcomes. Each chapter is clearly structured into three sections: the problem, the feeling of what happens, and the solution, providing an accessible and methodological framework. Based on extensive clinical research and experience, Dr Anu Arasu and her team cover critical concepts such as the gut-brain axis, mitochondrial function, and metabolic flexibility, allowing clinicians to develop a much more intricate approach to their client care.
