What is nutrition?

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 mainutrition,food allergies ,mettabolic diseases, etc.
As the developed world becomes increasingly diet conscious, you are bombarded with more and more information about why nutrition is important for your health, but is it really necessary? After all, eating is as much about pleasure as it is about fuelling our bodies and, as everybody knows, a little bit of what you fancy is good for you.

However, in our quest to eat the things we like, it is important not to lose sight of the simple fact that the calories we consume will have one of two effects on our bodies: they will either add to the nutrient store or they will sap nutrients from the body in an effort to metabolize them.

Obviously, if you are eating a lot of junk food, your body is not gaining any nutrients, but, more alarmingly, the nutrients in your body are being used to digest the junk that you have eaten. If this pattern persists, it does not take long for your body to become deficient in vital vitamins and minerals. Because unhealthy foods use up nutrient resources, it is possible to be overweight and suffer from malnutrition.
