The food nutrition is a very important thing for the people. Nutrition, nourishment, or aliment, is the supply of materials - food - required by organisms and cells to stay alive. In science and human medicine, nutrition is the science or practice of consuming and utilizing foods.Nutritional science studies how the body breaks food down (catabolism) and repairs and creates cells and tissue (anabolism) - catabolism and anabolism = metabolism. Nutritional science also examines how the body responds to food.As molecular biology, biochemistry and genetics advance, nutrition has become more focused on the steps of biochemical sequences through which substances inside us and other living organisms are transformed from one form to another - metabolism and metabolic pathways.
Nutrition also focuses on how diseases, conditions and problems can be prevented or lessened with a healthy diet.
In addition, nutrition involves identifying how certain diseases, conditions or problems may be caused by dietary factors, such as poor diet (malnutrition), food allergies, metabolic diseases, etc.
researchers from the Karolinska Institute, Sweden found that people who ate their "five-a-day" portions of fruit-and-veggies tended to live longer than those who did not. Their findings were published in the American Journal of Clinical Nutrition (July 2013 issue).
Nutritional balance is essential to maintain health and
central to preventing major diseases, importantly type 2
diabetes1,2, coronary heart disease, stroke and cancer.
Obesity, a disease that has had an international
classification of disease code since 1948, has a complex
aetiology, being influenced by genetic, metabolic and
environmental factors. Both overweight and obesity affect
health and favour the development of secondary
. The prevalence of obesity in the UK has
doubled over the last 10 years and is recognised as
reaching epidemic status by the World Health Organization4
. In the UK half of women and two-thirds of men are
overweight or obese, with 20% of all adults being obese5,6.
The estimated cost of obesity to health services is 4–7% of
the total healthcare budget5
Multidisciplinary primary healthcare teams face a range
of nutritional issues on which they are required to provide
. They are considered a trusted source of nutritional
advice, and primary care is the suggested appropriate
setting for effective weight management8
. Patients view
general practitioners (GPs) as the main source of
information about nutrition9
. They are accessible to 98%
of the population, who each consults around five times
annually10. Practice nurses (PNs) have an important role in
providing nutritional advice11. Dietitians provide a training
resource for other professionals and regard themselves as
potential leaders in the weight management field12.
National clinical guidelines, available to all health
professionals, provide resources for the nutritional
management of patients in routine practice and appropriate
approaches for prevention8

in the principles of nutrition would ensure clarity when

healthy eating, national dietary targets13 and weight
The present study aimed to document the knowledge,
attitudes, beliefs and eating habits of primary care health
professionals with respect to obesity, nutrition and weight
management.likely to agree with the statement (P , 0.01). Those GPs
who had read the SIGN clinical guideline on obesity8 were
more likely to recognise the value of physical activity in
preventing weight gain (P , 0.01). And We know, the food that we eat is digested and absorbed it is utilized by the body. Food helps us in staying healthy. What do we mean by the term ‘Health’? How do we know if a person is healthy? What is meant by the term ‘Nutrition’? Our diet should be such that it meets our nutritional requirements and thus helps us in our health. Although food occupies the first position in the hierarchy of our needs, ignorance of many basic facts relating to food and nutrition is still widespread. All of us eat food every day – but have we ever paused to consider if our diet is balanced? In fact, do we even know what kinds and amounts of foods would make our diet balanced and lead us toward good health? Buying and cooking foodstuffs is a common experience for all of us. However, when purchasing, do we really know hoe to select the food items? Do we know the household ways of finding out whether the food item is adulterated? If the diet is not balanced the result would be malnutrition and nutritional deficiency diseases. So, we find out the type of diet that should be eaten by a person who is suffering from a disease – from fever, diarrhoea, diabetes or hypertension.These three factors work together and support each other to build or deteriorate the good health that is desired by all of us.A number of studies have explored the phenomenon
