What is nutrition?
Shortcomings and men
In the last century, it has demonstrated the link between nutritional deficiencies and serious diseases. These various forms of malnutrition remain nowadays public health problems in developing countries, such as blindness due to vitamin A or cretinism caused by iodine deficiency. However, it is well after the disappearance of major nutritional deficiencies in Europe that the idea that any malnutrition certain diseases could be linked to nutritional factors, and since 60 years, research on the links between diet and health has made enormous progress.
A public health problem
It is now proven that the two biggest causes of death in France - cardiovascular disease and cancer - are linked to the way we eat. We also know that dietary factors are associated with the occurrence of many other widespread diseases such as diabetes, osteoporosis or obesity and a “good” nutrition is a key factor for a “good” health. For example atherosclerosis, a phenomenon hardening of the artery wall, sometimes starts early in life and can be halted or even reversed if we limit saturated fatty acids in food. Likewise we can be genetically predisposed to diabetes but never to be touched by the disease if it maintains an acceptable weight. Finally we know the importance of consuming dietary fibre to reduce the risk of colon cancer.
Food and performance
But beyond the protective role or conversely “at risk” of certain nutrients (vitamins blessed, cholesterol banned!), The notion of better nutrition guarantee better health in the broadest sense has gained ground. The role of food themselves and nutritional behaviour on the physical and intellectual performances, on resistance to infections or even in the fight against aging are commonly accepted. It is also clear that nutrition alone is not the only guarantee for better health or longer life, but it comes in addition to regular physical exercise, reducing consumption tobacco and alcohol, stress control, limiting the exposure to environmental risks and other factors improving the quality of life.
