Lifestyle and environmental factors have an influence on nutritional status. In order to enhance uptake and utilisation of both macro and micronutrients, it is important to have a balanced diet in line with the Balance of Good Health guidelines which focus on eating foods in variable amounts from each food group (see Know How guide, Part 6). The British Dietetic Association (1999) argues that a balanced diet will meet the needs of most people, but advises that those who wish to take a vitamin and/or mineral supplement should choose one that is in line with the UK Dietary Reference Values, so as to avoid the risk of overdosing. Other activities that will contribute to a healthy lifestyle are: Regular physical activity, preferably one which is enjoyed A limited amount of stress Drinking only moderate quantities of alcohol.
