Telomeres: What Is It And Does It Influence Aging?

Besides looking at the mirror, another objective way of telling how fast a person is aging is through telomere testing. Before anything else, what are telomeres? Telomeres are sections of DNA at the end of each chromosome that serves as a cap to your genetic material. Every time a cell replicates, its telomere will become shorter. Shorter telomeres imply a shorter life span for the cell.

What effect does telomere length have on my health and wellness? Age adjusted telomere length is the best method to date to assess biological age using structural analysis of chromosomal change in the telomere. Serial evaluation of telomere length is an indicator of how rapidly one ages relative to a normal population. Therapies directed at slowing the loss of telomere length may slow aging and age-related diseases.

Does diet have any effect on telomere length and repair? An inflammatory diet, or one that increases oxidative stress will shorten telomeres faster. This would include refined carbohydrates, fast foods, processed foods, sodas, artificial sweeteners, trans fats and saturated fats. A diet with large amount and variety of antioxidants that improve oxidative defense and reduces oxidative stress will slow telomere shortening. Consumption of 10 servings of fresh and relatively uncooked fruits and vegetables , mixed fiber, monounsaturated fats, omega-3 fatty acids, cold water fish and high quality vegetable proteins can prevent premature shortening. In addition, caloric restriction is advised combined with an exercise program. Fasting for 12 hours each night at least 4 days per week may also be protective.

What lifestyle modifications are likely to be helpful? One should achieve ideal body weight and body composition with low body fat (less than 22% for women and less than 16% for men). Decreasing visceral fat is very important. Regular aerobic and resistance exercise for at least one hour per day, sleeping for at least 8 hours per night, stress reduction, discontinuation of all tobacco products and bioidentical hormone therapy may decrease the rate of telomere loss.

How do you measure telomere length? The Patient Telomere Score is calculated based on white blood cells (T-lymphocytes). This is the average compared to telomere length on lymphocytes from a sample of the American population in the same age range. The higher the telomere score, the “younger” the cells. A Telomere Score that is above the average line is desirable.

What can I do to reduce my rate of telomere loss? Shorter telomeres have been associated with metabolic abnormalities, obesity, and several degenerative diseases including cancer, dementia, and cardiovascular disease. In vitro studies have shown that telomeres are highly susceptible to oxidative stress, which will shorten telomere length and enhance cellular aging. Minimizing associated risk factors that are linked to shortened telomere activity is recommended and include:

Reduce oxidative stress

Correct micronutrient deficiencies, especially vitamin D

Change sedentary lifestyle, increase physical activity

Avoid weight gain or obesity

Correct insulin resistance

I want my coffee now!

Facts about coffee. It is a beverage prepared from the coffee seeds, otherwise known as “coffee beans”, of the coffee plant. It is grown primarily in agricultural communities in approximately 70 countries throughout the world. It was discovered in the Middle East where it’s cultivation spread throughout the Arab world. It is now consumed by more people all over the world. Just look at the popularity of Starbuck’s or Peet’s or Seattle’s Best Coffee in the US alone. Anyway, what are the benefits of drinking coffee? People who take it regularly do so because it perks them up or gives them energy (due to the caffeine content which has stimulating properties). One disturbing fact about coffee though is that it’s one of the most heavily pesticides crops in the world. So, if you’re going to have your coffee, choose sustainably-produced, organic coffee at least. Decaf coffee is another issue all by itself. During the decaffeination process, chemicals such as formaldehyde, are used which actually makes the coffee worse. So, for people who want their decaf coffee, find one that’s processed without toxic chemicals. And perhaps, have your adrenals checked out by a holistic practitioner if you’re totally addicted or dependent on coffee in general. One thing more, have you ever heard of the coffee fruit? It’s basically the whole fruit with the beans and the flesh all intact. The whole fruit has more beneficial nutrients than the coffee bean alone. It is rich in antioxidants called phenolic acids as well as beneficial polysaccharides. Antioxidants, as we all know, fight off free radicals while polysaccharides enhance cellular communication (which is beneficial for the immune system in particular). I’ll have my coffee fruit instead!

I Hate Radicals!

The lipid peroxidation mechanism shows a singl...

Free radicals, that is! Free radicals are highly unstable atoms or molecules that have unpaired electrons. In order to maintain stability, they steal electrons from other molecules such as our cells thereby causing cell damage. A good analogy would be a codependent/clingy person. He or she always has to be with someone to thrive or even survive. That ain’t fun! Anyhow, excessive free radical formation leads to premature aging and nobody wants that. To fight against free radicals, we need to take antioxidants. Antioxidants are molecules that basically donates electrons to free radicals which then neutralize them and prevent them from damaging other cells. Antioxidants come in the form of vitamins (Vitamins A, C and E), minerals (zinc, selenium), amino acids (glutathione), herbs (ginkgo), essential oils (clove essential oil) and other nutrients (resveratrol). Antioxidants typically turn into free radicals once they donate their electrons. That’s why it’s always a good idea to take a good mix of antioxidants rather than just taking an isolated one. Among the antioxidants by the way, glutathione is the only one that doesn’t turn into a free radical. Neat, huh?

Vitamin D

Okay, vitamin D has been so much in the news lately. And for good reason! However, we’re not just seeing a deficiency in vitamin D but also deficiencies in B vitamins as well, minerals (like magnesium and potassium), essential fatty acids and antioxidants like glutathione. What could be the reason behind these deficiencies? Besides our depleted soils, the refining of our food causes these problems. And then, there’s a small but significant fraction of the population who have malabsorption issues. As far as vitamin D is concerned, it’s our lack of exposure to the sun’s rays that’s causing this deficiency. We normally don’t see it in people living in the tropics but as the use of sun block (that are petroleum-based) gets marketed heavily (and people there use skin whitening agents!), we will see more deficiency states in those areas. Vitamin D, besides being good for your teeth and bones is an immune modulator. Research shows that is can actually protect against certain forms of cancer! To see if you have optimal levels, have your levels checked (OH-vitamin D) pronto!
