What is Your Biological Age?
Do you watch the Biggest Loser? If so, you have seen each contestant visit a doctor at the start of the season and many times they’ll learn their actual ‘biological’ age. This usually ends up being a shocker, such as a 28 year-old whose physical condition is that of a 55 year-old or something drastic like that. Telomeres are a tool that can be used to fairly accurately identify your biological age.
I recently participated in a webinar hosted by Spectra Cell Laboratories and lead by Dr. Mark Houston discussing telomeres.
What is a telomere?
Telomeres are a DNA sequence that appears at the end of each chromosome. Chromosomes comprised of DNA are in each cell of our body. Our DNA is protected at each end by telomeres. Dr. Houston describes a telomere as a safety cap or ball cap on the end of each chromosome. They protect the chromosome and DNA from things like oxidative stress. As the telomere becomes damaged the chromosome and cell function ineffectively the cell begins to die.
Telomere Shortening
As a normal part of aging, telomeres become shorter. Once a telomere becomes shortened there is no way to lengthen the telomere.
There are many factors that influence how quickly telomeres shorten. Here are some of the factors that impact telomere length:
Dr. Houston Answers Your Top Heart Health Questions – Part 4
All right, this is the final series of questions and answers from my interview with Dr. Mark Houston in February 2010.
Lisa Nelson RD: Does grape seed really help lower blood pressure?
Dr. Houston: Yes, systolic blood pressure is reduced about 8 mm Hg and diastolic blood pressure 5 mm Hg. It is in the formulas mentioned above.
Lisa Nelson RD: What causes of an enlarged heart and are there ways to reverse an enlarged heart?
Dr. Houston Answers Your Top Heart Health Questions – Part 3
Here’s another four questions with answers from my interview with Dr. Mark Houston in February 2010.
Lisa Nelson RD: If someone has been on blood pressure medication for many years and they take steps to lose weight and improve their diet is it likely they’ll be able to discontinue their medication or will they be on medications for life?
Dr. Houston: About a 60% of patients that follow the guidelines in the book that I wrote on What Your Doctor May Not Tell You About Hypertension can stop meds over 6-12 months if they do everything correct as outlined.
Lisa Nelson RD: If someone is newly diagnosed with high blood pressure, how much time should be allowed if the individual prefers to make diet and lifestyle changes to lower the blood pressure before turning to medication?
Dr. Houston: I recommend getting the blood pressure down soon with both meds and lifestyle changes to protect the arteries and reduce cardiovascular disease based on some recent studies. Later on, if blood pressure is controlled then you can taper the medications.
Lisa Nelson RD: Do any of the over-the-counter meds for high blood pressure and high cholesterol work – or are they just snake oil ads?
Dr. Houston: There are some good supplements that work for blood pressure and cholesterol, but most over the counter are not good. The best source is BIOTICS RESEARCH at 1-800-231-5777. For blood pressure use VASCULOSIRT. Also for blood pressure is CARDIOSIRT BP (this one will be out in the spring). These will reduce blood pressure well along with the lifestyle changes recommended in the book above. The best for cholesterols is LIPIDSIRT. It can be used with the new niacin and red yeast rice from BIOTICS if needed. This may decrease cholesterol with the combination by 40-50%.
Lisa Nelson RD: How effective do you feel the supplements l-arginine, coQ10, and omega 3 are at preventing cardiac problems?
Dr. Houston: I would use omega 3 fatty acids in almost everyone to reduce heart attack, stroke, blood pressure, improve triglycerides and improve memory. The best omega 3 fatty acid on the market is EFA-SIRT SUPREME from BIOTICS research at 1800-231-5777. The CoQ10 is excellent as well. Doses of about 100 to 200 mg of a good quality CoQ10 will lower systolic blood pressure about 15 mm Hg and diastolic blood pressure about 10 mm Hg in 50% of patients. The CoQ10 is in both the VASCULOSIRT AND THE CARDIOSIRT BP from BIOTICS at 1-800-231-5777.

Dr. Houston Answers Your Top Heart Health Questions – Part 2
Here are more of the questions and answers from my interview with Dr. Mark Houston in February 2010.
Lisa Nelson RD: Is there a connection between blood pressure and heart rate?
Dr. Houston: If blood pressure increases, normally the heart rate should decrease. However, in some patient with dysregulation of the autonomic nervous system the heart rate may increase with the blood pressure.
Lisa Nelson RD: Blood pressure fluctuation – What causes blood pressure to fluctuate drastically throughout the day? Is it something to worry about?
Dr. Houston: Most people have fluctuations during the day due to the normal circadian rhythm (high in AM and low in PM). Stress, anger, eating, exercise, rest, meditation, coffee are some of the things that will alter blood pressure. About 60 % of patients that drink coffee have increase blood pressure for several hours after consumption.
Lisa Nelson RD: What is the risk of not treating high blood pressure? For example, someone has a blood pressure of 160/100, but they feel perfectly fine. Why should they be concerned and seek treatment?
Dr. Houston: Heart attack, stroke, heart failure, kidney failure, loss of vision, aortic rupture, valve dysfunction, atherosclerosis. Hypertension is the silent killer. At this level the arteries will be damaged over time and all of these complications will occur. At that high level of blood pressure one will decrease life expectancy by about 15 years or more.
Lisa Nelson RD: Do blood pressure recommendations change with age?
Dr. Houston: A normal blood pressure is 120/80 regardless of age. If it goes up with age it means the arteries are not healthy, but very stiff.
Lisa Nelson RD: What is a normal blood pressure response post exercise? How quickly should heart rate return to normal post exercise?
Dr. Houston: Blood pressure will fall for several hours after exercise depending on hydration status and severity and length of exercise. Usually systolic (top number) blood pressure falls about 10-15 mm Hg and diastolic (bottom number) 5-10 mm Hg. Heart rate should return to normal within 2 minutes post exercise.

He speaks nationally and internationally on hypertension and has written three best-selling books – The Handbook of Antihypertensive Therapy, Vascular Biology for the Clinician, and What Your Doctor Does Not Tell You About Hypertension: The Revolutionary Nutrition and Lifestyle Program to Help Fight High Blood Pressure.
The list of Dr. Houston’s accomplishments goes on and on. I’ve covered just some of the highlights of his career above. With all of his research commitments, speaking engagements, etcetera; he still works with patients one-on-one in Nashville, Tennessee, and teaches Vanderbilt medical students, interns, and residents.
This is a great opportunity for you to get your questions answered.
