Understanding cellular aging
We all want to look and feel great for as long as possible. But if you have ever been to a school reunion, you might have noticed something interesting: Some of your classmates look older than others. Why is there such a difference in the rate at which people age? Scientists have discovered that it all starts inside our cells.
For most of us, aging means loss of muscle strength, bone density, lung capacity, and memory, and our risk for conditions such as diabetes, cardiovascular disease, dementia, and cancer all increase. When you graph the incidence of disease versus age, you notice something rather striking: Many chronic disease conditions are rare when we are young, but their incidence begins to increase around age 50. To scientists who study aging, this upsurge around age 50 suggests that there might be a common reason underlying the onset of some of the age-related diseases, and that may be cellular aging.
When we are born, we start out with a large population of healthy cells; then, ultraviolet radiation, environmental toxins, stress, and poor diet do damage to our cells. The more our cells are exposed, the more damage accumulates. It is this accumulated damage that eventually crosses a threshold that may lead to recognizable disease.
Nutrition for your cells
What you really want to do is help your cells protect and repair themselves throughout life to help delay the onset of disease and better control the risks. One key to understanding cellular defense is knowing that cells require certain nutrients in the right amounts to be able to function normally to protect and repair themselves. Read more…
