Healthy eating

It is Healthy Eating Week in the UK! And, okay, we’ve all heard the advice before: eat five portions of fruit and vegetables a day, drink six to eight glasses of water, consume less sugar. But why is healthy eating so important?

A balanced diet plays an essential role in maintaining overall good health. Overeating can lead to conditions like type 2 diabetes and heart disease, while obesity has been linked to a higher risk of cancer.

Undereating or cutting out major food groups can also seriously affect your health. The human body needs protein, carbohydrates, fat, vitamins and minerals to function properly — so, whether you are vegan, gluten-free or lactose intolerant, it is still important to make sure you are getting enough of each of of these nutrients.

But healthy eating is not just about the physical benefits. Despite myths about “comfort food” and the urge to fill up on sugar, scientists have found that eating well actually makes us happier. A balanced diet and regular exercise are two of the best ways to improve our mental health.

This week, why not set yourself a healthy lifestyle challenge and see whether it helps to improve your mood?
