How Long Do You Want To Live?

Many of us are fascinated by stories of unusual longevity.  It seems every television network has some variation of a segment celebrating birthdays at or around 100 years old.  Perhaps it is because those over the century mark are one of the fastest growing segments of the United States population.  So often, getting to triple digits, living longer, and being the oldest kid on the block seems to be our obsession.  We like thinking about how long we want to live, rather than how well we want to live.  Is there a way to do both – live well, and live long?

Can Dairy Fat Reduce Your Risk of Diabetes?

We are all aware of the current obesity trend in this country and across the globe.  Avoiding fat in our diet has been the conventional mantra now for the last 4 or 5 decades.  But what has this low-fat obsession gotten us?  Well, Americans are now fatter than ever.  Paralleling that trend has been a dramatic rise in diabetes cases and, cardiovascular disease remains the number one killer of Americans.  New research has focused on a trans fat component found mainly in dairy fat that may ward off type 2 diabetes and protect cardiovascular health. While more research is needed, it suggests fats may play a more complex role in human health than previously acknowledged. Read the rest of this entry »

Sweet Dreams

It may seem obvious that sleep is beneficial. Even without fully grasping what sleep does for us, we know that going without sleep for too long makes us feel terrible, and that getting a good night’s sleep can make us feel ready to take on the world.  When we awaken from a restful sleep, we feel more alert, more energetic, happier, and better able to function. However, the fact that sleep makes us feel better and that going without sleep makes us feel worse only begins to explain why sleep might be necessary. Numerous studies have linked poor sleep with an increased risk of cardiovascular disease, a weakened immune system, cancers, high blood pressure, obesity and Type 2 diabetes.

47,000 Deaths and Counting

It is inconceivable that a product could remain on the market after it has been directly linked to tens of thousands of deaths.  But this is exactly the case we have with two popular diabetes drugs, Avandia and Actos.

Avandia was introduced in 1999 and a study performed by its maker, SmithKline Beechem (later acquired by Glaxo) found that it posed a significantly increased risk of cardiovascular events and bone fractures.  What did they do?  They suppressed the data for the next 11 years!  Read the rest of this entry »

Are You Losing Muscle Mass?

“Normal” aging is typically accompanied by easier weight gain and, along with declining hormones and decreased physical activity can reduce muscle mass, lead to frailty and a higher prevalence of metabolic disorders.  This insidious, age-related loss of muscle mass is called sarcopenia.

In many respects, sarcopenia is to muscle what osteoporosis is to bone.  The typical American gains one pound of fat and loses a half pound of muscle yearly between age 30 and 60.  Deterioration of muscle and loss of muscular strength is a major reason elderly lose mobility and cannot remain living independently.   Read the rest of this entry »

Statins and Cholesterol: Hope or Hype?

Cholesterol had become the indisputable villain for heart disease over the last several decades.  After all, it seemed intuitive that cholesterol was the cause of heart disease, since cholesterol made up a large portion of the vascular plaque that characterized atherosclerotic heart disease.  But as the understanding of cholesterol metabolism has become better delineated, the connection between cholesterol and the cause of heart disease has become considerably more tenuous, and the role of statin drugs questionable.

Are You Playing With A Loaded Gun?

One of the most shocking surprises to emerge from the Human Genome Project in 2003 is the discovery that we are the proud owners of a paltry 30,000 genes — barely twice the number of a fruit fly.

After a decade of hype surrounding the project that gave us the full sequence of our human genome, and the regular discovery of genes for killer diseases and complex traits, this unexpected result led many scientists to a stunning conclusion. The seesaw struggle between our genes (nature) and the environment (nurture) had swung sharply in favor of nurture. “We simply do not have enough genes for this idea of biological determinism to be right,” asserted Craig Venter, president of Celera Genomics, one of the two teams that cracked the human genome.
