Diet and Nutrition: Metabolic Diseases

“You Are What You Eat; how to win and keep health with diet”, was the title of a book, that nutritionist Victor Lindlahr wrote in 1920s. Since then, several nutritionists have written extensively on this topic. Over the years, scientists, clinicians, policy makers, and professional societies, have offered contradictory advice of what to eat or what not to eat, and when to eat. In view of the fact, that my interests are focused on metabolic diseases, I will start this essay with some introduction to metabolism, as it modulates the activities at molecular, cellular, organ, and total body level. In brief, metabolism is the chemical process your body uses, to transform the food you eat into the fuel, that keeps you alive and well. Diet and nutrition by and large, consists of proteins, carbohydrates, fats and a variety of micronutrients.
