How nutrition and exercise effects the aging process
You are what you eat, the saying goes. This piece of wisdom underscores the body’s process of extracting nutrients from food; we get what we put in our bodies, whether it’s good or bad.
Some foods may actually combat the aging process because of the nutrients they contain. Under the free radical theory of aging, our bodies wear down as the result of cellular destruction by free radicals. These are molecules or atoms with an unattached electron, produced by normal body processes where oxygen is used, which seek to attach itself to another atom. These radicals can attach to a number of different molecules and atoms; if they attach to a cell’s mitochondrial DNA (mtDNA), damage can occur and the cell may eventually die.
Here’s where food comes in. Foods containing antioxidants have been shown to neutralize free radicals by stabilizing them. The theory goes that the more antioxidants (like vitamins C and E and beta carotene) are consumed through food, the less chance free radicals have to damage cellular structures, including skin cells.
Studies of the effectiveness of adding antioxidants to stabilize free radicals have come to different conclusions; definitively speaking, the jury’s still out. Still, physicians recommend eating a diet rich in antioxidants, such as colorful vegetables and cold-water fish like trout and salmon.
Perhaps one of the most obvious signs of aging is the stooped posture and trembling limbs of the elderly. These signs of aging can often be categorized as senile sarcopenia. It’s the result of a loss of muscle mass, which results from the death of motor neurons that control muscle fibers. When a mass of muscle fibers lose the neuron that controls them, they are left inactive, wither and die. In some cases, other neurons will bind themselves to abandoned muscle fibers. The result is an overloaded neuron that controls muscles with lessened precision. Sarcopenia accounts for sagging skin and wrinkles; as we lose muscle fibers beneath our facial skin, the tissue droops.
Luckily, studies have shown that sarcopenia can not only be decreased, its effects can even be reversed through resistance weight training. A 2004 Rutgers University study found that 45 minutes of resistance training three times a week for 12 weeks increased muscle fiber by an average of 32 percent and strength by an average of 30 percent.
