2 - Eating for Health and Wellbeing

Summary

Having a healthy diet is essential for physical health, brain health, cognition, and overall wellbeing regardless of age. A balanced diet, rich in fruits, vegetables, lean proteins, whole grains, and healthy fats, provides vital nutrients for optimal bodily functions and supports mental and emotional wellness. Obesity and Type 2 diabetes are prevalent, with obesity rates tripling since 1975 according to the World Health Organization (WHO). These conditions underscore the importance of healthy eating habits and maintaining an optimal body mass index (BMI). Understanding dietary components such as carbohydrates, proteins, and fats is crucial for making informed food choices. The Mediterranean and MIND diets exemplify healthy eating patterns linked to reduced disease risks and improved mental health. Moreover, dietary factors influence brain health and cognition through mechanisms like inflammation modulation and the gut–brain axis. Adopting and maintaining a healthy diet throughout life promotes longevity, energy, and overall fulfilment, making it a cornerstone of a vibrant lifestyle.
