Nutrition at Colgan Practice


A good diet is important for our health and can help us feel our best – but what is a good diet? Apart from breastmilk as a food for babies, no single food contains all the essential nutrients the body needs to stay healthy and work properly. For this reason, our diets should contain a variety of different foods, to help us get a wide range of nutrients that our bodies need. This is illustrated by the UK’s healthy eating model – the Eatwell Guide.

A good diet is important for good health. Eating a variety of foods can improve general wellbeing, reduce the risk of conditions including heart disease, stroke, some cancers, diabetes and osteoporosis (thin bones) and help you manage your weight. You need to eat sensibly, choosing a varied diet from a range of foods, not smoking and keeping active are all great ways to boost your health. Different types of food.
