Role of Nutrition in Diseasse

Diseases have changed now they are no more just infection but became deficiency diseases indicating need of new treatment i.e. therapeutic nutrition. Hippocrates rightly said let food be thy medicine and medicine be thy food.

The human diet was primarily composed of vegetables but as human evolved from gatherer to social life food preferences started to change gradually and processed food took place of raw food. The more processed food less nutritious it became, but more or less active Lifestyle halted development of metabolic disorder. Nowadays food we eat is finally processed and we lead sedentary life,both these facts alone are responsible for 99.9% of our diseases. Food is not only processed but is genetically modified hybrid and full of hazardous chemicals like ethane oxytocin etc.. which pose a very serious threat to human existence.

In this scenario going back to connect nutrition and active living is very helpful in correction of pathology is and in many cases cure of pathology. Some good examples are treatment of scurvy by Vitamin C anemia by Iron supplementation vitamin B deficiency by Vitamin B supplementation

But proposing a cure for all diseases by diet alone is oversimplification and at times harmful because diseases basically need medicine. Till now role of diet and nutrition was considered preventive rather therapeutic since deficiency is common due to poverty, issue of deficiency can be safely addressed with concept of RDA but advances in food technology hybrid crops and use of pesticides prompted evolution of RDA into ODA that is optimum daily allowance.

Optimum Nutrition is that field where simple nutrients turned into potent antioxidants, antibiotics, antidepressants and much more. This is a new field where pharmaceutical companies are ready to invest because the therapeutic activity of these nutrients does not have harmful effects of traditional drugs. The changing trend has favored growth of many concept and ideas like specific diet to cure cancer, detoxification, Juice Therapy, Phytonutrient's therapy and question the authenticity of many well established ideas and concepts.

  10. Boron– ODA is2 mg andis essential for healthy bone and brain function and alertness

  11. Silicon – ODA is 2.4 mg and is needed in formation of collagen and connective tissues
