Many of the dietary rules we traditionally follow are arbitrary, and do not have much relation to what we really should be doing. There is no exercise that can keep one's skin and body youthful, although a fit person undeniably looks much better, is healthier, and is likely to live longer. Remaining youthful looking fundamentally stems from one's genetic inheritance.
The science behind this essential 'dumb luck' depends on the life span of individual cells inside the human body. Each cell contains 46 chromosomes, which are derived from 23 mother and 23 father chromosomes. Each individual chromosome has a telomere at either end. The telomere, which is itself a DNA sequence, gives stability to the end of the chromosome, and prevents abnormal recombinations of the chromosomes. An enzyme, telomerase, replenishes the telomere across cell divisions. Telomerase is necessary for the maintenance and repair of the telomere, which extends the life of the cell. Telomerase does this by helping transfer genetic code information between nucleic acids. If telomerase is activated, the cell may become immortal. This however comes with a caveat, as cell immortality can be a hallmark of cancer.
The unbelievable implications in the possible control of the aging process of cells, which make up every organ in our body, illustrates why more simplistic efforts to control the 'uncontrollable' normally fail. The Fountain of Youth remains a mystery to all but authors of fictional novels, but is becoming tantalizingly closer to reality. Diet and exercise programs normally advertised on television and in magazines often demonstrate fads that make their proponents rich, and you lighter in the wallet. Until one of the aforementioned body metamorphosis programs promises to change one's genetic make-up, it will never achieve the results it promises.
Some of this is not ground breaking news; chromosomes have always operated in this way. For instance, if parents are long-lived, and other members of the family tend to be long-lived, there is a good chance for a person of that family to be long-lived. Your chromosomes have always predetermined your body's physiology, it's up to you to maximize it! Cutting edge techniques in Genetic Diagnosis, and Gene Therapy, may become available to help you live longer and better.
The purpose of this article is not to discourage people from eating more healthily, far from it. Rather, this article's intention is to provide a caveat for any miracle diets that promise the body of a supermodel for a person who is not genetically able to obtain this figure. As the saying goes, "beauty is only skin deep," so act accordingly! Healthy eating and exercise will help to maintain health and well being internally, but it is far fetched to believe that these acts can completely transform one's physical image.
