WELL-BALANCED diets

Over 2,000 years ago, Hippocrates observed that “each one of the substances of a man’s diet acts upon his body and changes it in some way, and upon these changes his whole life depends, whether he be in health, sickness, or convalescence.” Modern nutrition science continues to support this principle: in simple terms, we really are what we eat. The food we consume provides the raw materials used to build, repair, and maintain our bodies, while also supplying the energy required for everyday living—moving, thinking, exercising, and even keeping warm (no small task in the UK). Because the body is in a constant state of turnover, even in adulthood, an ongoing supply of nutrients is essential for long-term health and performance.

If we value our health, we must aim for a diet that is both adequate and well balanced—easier said than done. Many people associate the word diet with restriction, deprivation, or the joyless removal of biscuits, yet its true meaning is simply the habitual food and drink of a person. There is no inherent requirement for extremes or exclusion. Unfortunately, conflicting messages from social media, advertising, and popular culture have made it increasingly difficult to separate evidence-based guidance from nutritional fiction, turning food into a source of stress rather than enjoyment. Current nutritional consensus supports flexible, sustainable eating patterns that prioritise nutrient density, balance, and consistency over rigid rules—principles reflected in public health models such as the UK Eatwell Guide (https://www.nhs.uk/live-well/eat-well/food-guidelines-and-food-labels/the-eatwell-guide/).
