Is the fountain of youth right underneath your very nose?
Genes are like’ sub folders’, they are segments of DNA that are responsible for appearance, how your body works and almost everything related to life. Yet, alone, they are not the major player in how you age.
Only twenty to thirty percent of longevity relies on genetics. Interestingly researchers from the Spanish National Cancer Research Center and the Kuakinni Medical Center in Honolulu have identified two genes that seem to influence longevity. These genes are related to cholesterol (APO B: reduce the levels of LDL in the blood) and insulin (FOX03A: participates in insulin growth factor signaling). In the Lifespan Study (http://www.ncbi.nlm.nih.gov/pubmed/18765803), the FOX03A gene was associated with, “doubling or tripling the odds of living for at least 95-years” and found that the participants who lived had a lower waist-to-hip ratio, lower triglyceride levels, and lower glucose and insulin levels.”
This genetic component to the aging process therefore is tied to nutrition. What you eat has a major effect on cholesterol and insulin.
Living a low stress, healthy existence seems to be “the fountain of youth” we all would like to think there is a magic bullet. Standard of living, not pills or creams, is related to speeding or slowing down the aging process.
7 Anti-Aging Angels
- Smoking avoidance and cessation
- Limiting alcohol
- Reducing Stress
- Engaging in healthy relationships
- Exercising your mind
- Nutrition: carbohydrate and sugar negatively impacts cholesterol and insulin. Adequate hydration is one of the most important positive nutritional factors to avoid aging.
- Physical activity. Strength training has been extensively researched and has been found to reverse the aging process. “A 70-year-old active individual is probably younger from a biomarker standpoint – muscle strength, balance, body composition, blood pressure, cholesterol levels – than a 40-year-old inactive individual,’’ Miriam Nelson, a professor of nutrition at Tufts University, http://www.boston.com/lifestyle/health/articles/2012/03/05/stopping_age_related_muscle_loss/?page=2#sthash.uY0JTpEh.dpuf.
One main component of aging at the cellular level is oxidative stress (low anti-oxidant levels) and mitochondrial (considered the power houses of cells converts sugars to energy) dysfunction. Specifically resistance training increases antioxidants and improves mitochondrial function to reverse the aging process.
Melov and Tarnopolsky, from McMaster University Medical Center in Hamilton, Ontario, found that one hour of strength training twice a week for 6 and a half months resulted in anti-aging effects at the cellular level for a group of 70 year olds whose genetic profiles were similar to a group of 25-year-old volunteers. The resistance training was associated with 179 age-exercise related genes.
Exercise and strength training has also been shown to reduce stress, build self-esteem, increase metabolism, improve brain function, build muscle and bone along with so many other positive health benefits it is no surprise that there is a strong link to longevity.
Looking to stay young? The fountain of youth is within everyone’s grasp. Lifestyle is the secret. Strength training has been shown to have the most effect on turning back the “aging” clock. Eat right and make the 5 other “anti-aging angels” part of your life and stay in touch over the next hundred years!
