As nourishment researchers, we are often asked to advise colleagues as very well as users of the general public on diet regime and workout to promote superior health. But do we constantly practise what we preach? We each facial area issues to eating healthily.

We’re each based mostly in francophone nations around the world, and are all way too familiar with the shifting Mediterranean diet regime.

The strongest drive, in our practical experience, is the reminder that eating a wholesome and well balanced diet plan can assist system and thoughts to function optimally, top to greater research.
Where ever attainable, we need to select foodstuff that assists to strengthen focus, memory, mastering capabilities3 and even the immune procedure4. For instance, consuming oily fish these types of as clean tuna or mackerel often has been connected to improved cognitive factors5, probably owing to the presence of a big array of essential vitamins and minerals, such as vitamin D and crucial fatty acids. With each other, we wrote our possess evidence-centered dietary ‘commandments’ to support us get via our day-to-day duties and hold our physique and spirit likely — no matter if in the laboratory or in entrance of our computer system screens — and to help us come to feel additional energetic and inspired at function.
