Want to Live Longer?… Make Sure You Are Supplementing with Vitamin D!


A recent study published in the journal Diabetes Care, found that people who are diagnosed with “metabolic syndrome” (estimated to exist in 33% of Americans) maintaining optimal levels of Vitamin D reduces the risk of death due to cardiovascular disease by 66% and the risk of dying from all causes by 75%.

In addition, the study found that risk of sudden death decreased by 85% and the risk of dying from congestive heart failure by 76%.

Metabolic Syndrome (METs) is a condition defined by the presences of 3 or more of the following conditions:

  • central obesity: waist circumference ≥ 102 cm or 40 inches (male), ≥ 88 cm or 36 inches(female)
  • dyslipidemia: Triglycerides levels equal to or greater than  1.7 mmol/L (150 mg/dl)
  • dyslipidemia: HDL-C less than 40 mg/dL (male),  less than 50 mg/dL (female)
  • blood pressure equal to or greater than 130/85 mmHg
  • fasting plasma glucose equal to or greater than 6.1 mmol/L (110 mg/dl)

The presence of METs increases the risk of developing both type II diabetes and heart disease.

Your vitamin D levels can easily be checked by your physician. Optimum levels should be around 125 nmol/liter or 40-60 ng/ml.

I suggest taking at least 1000 IU of vitamin D-3 daily and checking your levels to make sure that this dose is getting you to the optimum levels described above.

There are several other significant health benefits that are being proposed for Vitamin D.  Not only does Vitamin D  reduce the risk of cardiovascular disease, it helps fight infections of all kinds including, colds and the flu.  Vitamin D helps your immune system attack and destroy bacteria and viruses and helps prevent autoimmune diseases.

30 minutes a day to exercise doesn’t sound so difficult until you try to do it and struggle finding the time.  Then the mindset is, well if I can’t do the 30 minutes, I may as well not do anything because it’s not going to help anyway.

The really good news is that researchers from Taiwan’s National Health Research Institute studied 416,000 participants over a 13 year period during which their health records and level of physical activity was monitored and recorded. Their findings were that only 15 minutes a day of moderate exercise, like brisk walking, was enough to increase life expectancy by 3 years compared to people who didn’t put in the 15 minutes a day.

It turns out the first 15 minutes yields tremendous benefits and in addition to increasing life expectancy by 3 years, the active group had a 10% reduction in cancer risk as well. This info should encourage everyone to get out there and reap the benefits of just putting in 15 minutes a day.

The results of a long-term study carried out in the Netherlands and published in the respected American Journal of Clinical Nutrition found that if we control 4 specific factors we can live 8.5 years for men and a whopping 15 years for women longer than people who don’t control these factors.



The 4 factors are:

  • ·        Not Smoking
  • ·        Nutritional Pattern:  Eating Mediterranean Diet Type Foods
  • ·        Physical Activity for at least 30 minutes a day
  • ·        Body Weight- keeping Body Mass Index (BMI) between 18 to 25.

The study started in 1986 and included over 120,000 men and women from ages 55-69.  It studied the risk of premature death in people who both controlled these 4 factors and those who didn’t.

Women who controlled these factors had the same risk of premature death as women who were 15 years younger but didn’t.  To put it another way, a 55 year old women who controlled these 4 factors had the same risk of premature death as a 40 year old woman, who didn’t.

A 65 year old man who controlled them had the same risk of premature death as a 56.5 year old man who didn’t.

The exciting implication of this research is that for those of you who really want to lose weight and want to do it properly, 3 of the 4 life extending factors will automatically be incorporated into your weight loss regimen: Exercise, nutritional pattern and reduction of BMI. (The 4th factor, smoking, though obviously recommended, is a separate personal decision).

To calculate your BMI divide your weight in pounds by your height in inches times itself and multiply that amount by 703.

For example, a woman who weighs 140 lbs and is 5’4” (64 inches) the calculation would be:

140 divided by 4096 (which is 64X64) = .03418 X 703 = 24 which is the BMI and in the acceptable range.

Just because the BMI is in the “healthy, acceptable” range, this doesn’t mean that a lower BMI wouldn’t be aesthetically more pleasing to some women.

If the woman in the above example experienced healthy weight loss and dropped to 120 lbs her BMI would be:

120 divided by 4096= .0293 X 703 = 20.6 the new BMI.

For those of you who don’t like doing math, the link below will automatically calculate your BMI for you.

In a subsequent article, that will be released within the next few days, some eating and exercise hints that make losing weight simpler and less of a challenge, will be discussed.

Calorie Restriction = Weight Loss & Longevity

Calories and Weight Loss -

A great deal of research regarding the life-extending benefits of “caloric restriction” is being published. To date, most of it, though promising, demonstrated benefits in non-human models.

Recently a particularly encouraging study on Labrador retriever dogs, indicated that cutting calories intake by 30% increased the life span of these dogs by 2 years. Given the average life span of this species, that was an increase of over 20%. Quite remarkable.

I would strongly suggest to those who have dogs (especially larger dogs 50+) to consider cutting back their pets caloric intake.

I did this with my 4 year old, black German shepherd and his weight went from 100 lbs to 86lbs and his energy levels increased significantly. Several people upon meeting him for the first time, thought he was a puppy, no more than 8-12 months old.German Shepard Calorie Restriction Longevity

Though proof of this concept for humans is not yet established, it is my bet that it will be. In some respects, digesting and metabolizing food puts demands on your body that can be considered contributors to aging.

The more one eats, the more free radicals they will generate, the more their bodies will have to detoxify and remove bi-products of digestion and metabolism both systemically and cellularly. The benefits of reducing calories goes beyond just the weight loss that occurs. Calorie restriction/reduction may be the best form of life insurance we can get, and it’s free.

Now a welcomed study from Tufts University has shown that caloric restriction in humans actually boosts our immune response. As humans age, their immune response tends to decline and become less efficient. Though animal studies have previously shown that caloric restriction improves immune function, this study is the first to show the same benefit in humans.

46 men and women who were overweight but not obese, were placed on calorie restricted diets reducing intake by either 10% or 30% for six months. At the end of that period test measuring DTH (Delayed Type Hypersensitivity, a test measuring whole body immune function) and T-cell function (white blood cells involved in immune response) improved significantly in both groups.

For those readers who would like to read the research, this study was funded by the Agricultural Research Service of the Department of Agriculture of the U.S. government. The lead researcher was Simin Nikbin Meydani and the article was published in 2009 in the Journal of Gerontology.
