No matter what school of nutrition or medical philosophy you subscribe to, the scientific evidence is clear that nutrition and disease are inextricably linked. Even the early Greeks concluded that body organs and tissues continually wear out and most be replaced. So what is this relationship all about?
In its simplistic form, the nutrient blocks of the body consists of protein and amino acids; carbohydrates; sugars; salts; vitamins; fiber; lipids; cholesterol; and minerals. Diseases and syndromes result when there is an inappropriate intake and imbalance of these essential nutrients and sources of energy that fuel our body tissues and cells. What is the common source of them all? That’s right, FOOD!
Many people interpret the “experts’ ” advice as words of counsel written in stone. Are nutritional guidelines written in stone? Not according to the Food and Nutrition Board of the National Academy of Sciences. The needs for energy and essential nutrients vary with age, sex, physiological state, heredity and physical activity. The nutritional needs of the young growing infant are distinctively different from those of the inactive octogenarian; those of the various active young persons differ from those of the sedentary, obese person of middle age. Variation in needs due to age and sex are taken into account in the formulation of Recommended Dietary Allowance.
Nutritional guidelines are exactly that. As long as we stay within the recommended parameters and don’t stray too far away and stay off-course too long, we will tend to eat proper and well-balanced meals. The key is to know what are individual parameters are based on our own health status, preferences for types of foods and healthy food choice alternatives. The information in this guide is not meant to replace the advice of a medical professional. If you have any questions or concerns, you should talk to a doctor, nurse, or dietitian about your specific nutritional needs.
