The history of clinical nutrition ,or the study of the 
              relationship between health and how the body takes in and
              utilizes food substances,can be divided into four distinct 
line        eras:the first began in the nineteenth century and extended 
              into the early twentieth century when it was recognized for
              the first time that food contained constituents that were 
              essential for human function and that different foods 
              provided different amounts of these essential agents.Near 
              the end of this era,research studues demonstrated that rapid
(10)       weight loss was assosiated with nitrogen imbalance and 
              could only be rectified by providing adequate dietary 
              protein associated with certain foods.
                      The second era was initiated in the early decades of 
              the twentieth century and might be called”the vitamin 
 (15)      period”.Vitamin came to be recognized in foods,and
              deficiency syndromes were described.As vitamins become
              recognized as essential food constituents necessary for 
              health,it became tempting to suggest that every disease and
              condition for which there had been no previous effective
(20)       treatment might be responsive to vitamin therapy.At that 
              point in time,medical schools started to become more 
              interested in having their curricula integrate nutritional 
              concepts into the basic sciences.Much  of the focus of this
              education was on the recognition of vitamin deficiency 
(25)       symptoms.Herein lay the beginning of what ultimately 
             turned from ignorance to denial of the value of nutritional 
             therapies in medicine.Reckless claims were made for 
             effects of vitamins that went far beyond what could 
             actually be achieved from the use of them.
(30)               In the third era of nutritional history in the early 
             1950’s to mid-1960’s,vitamin therapy began to fall into
             disrepute.Concomitant with this,nutrition education in 
             medical schools also became less popular.It was just 
             decade before this that many drug companies had found
(35)      their vitamin sales skyrocketing and were quick to supply
             practicing physicians with generous samples of vitamins 
             and literature extolling the virtue of supplementation for a
             variety of health-related conditions.Expectations as to the
             success of vitamins in disease control were exaggerated.
(40)      As is known in retrospect,vitamin and mineral therapies 
             are much less effective when applied to health-crisis
             conditions than when applied to long-term problems of 
             under nutrition that lead to chronic health problems.
