Busting the Cholesterol Myths

Monday, April 6th, 2009

The Cholesterol MythsAlthough there are many different forms of heart disease, atherosclerosis is the one that typically inspires most concern. It’s characterized by hardened arteries that restrict the flow of blood to the heart and is caused by the scar tissue created through the repair of cellular damage within the arterial lining. The scar tissue associated with atherosclerosis is susceptible to rupturing and can cause a blood clot that may further restrict, or even completely block, the flow of blood to the heart.

The materials that accumulate in the artery wall in response to cell damage are collectively referred to as plaque. As one of these materials, cholesterol earned it’s bad reputation simply by being at the scene of the crime.

The Truth About Scientific Research

Saturday, January 3rd, 2009

A claim that’s supported by scientific research has a certain seriousness to it that makes it feel verified and trustworthy. But is it?

The Pursuit of Truth

Many of the scientific discoveries and inventions that have occurred up until now are absolutely amazing. Using our advanced knowledge to uncover unknown truths is a marvelous thing. Finding truth is the core of what research is and is what drives scientists to dedicate themselves to it. But that doesn’t mean every piece of published research is worthy of this distinction.

To avoid having any influence on the results of a research study, researchers must have a strictly unbiased outlook on the results. Although this can be hard to accomplish, bias can inadvertently lead to changes in the design and protocol of a study that ultimately alter it’s outcome. A biased study leads to a biased truth which isn’t really the truth at all.

A Conflict of Interest

In today’s fiercely competitive marketplace, corporations are looking for any advantage they can get to sell their products. For a company selling a product in the health and fitness field, one of the most valuable advantages they can get is to back their product’s claim with scientific research. But keep in mind that a scientific study can be very expensive and cost millions of dollars. Unfortunately, this all leads to a situation where potential for profit drives the need for research rather than the need for honest answers.

Is Science Smarter Than Nature?

Tuesday, December 30th, 2008

The complexity and balance of nature is simply amazing and we may only be scratching the surface toward understanding how it all works. Even the complexity of a single cell is quite amazing, so it can be overwhelming when you consider that we each have trillions of them.

Many of these cells are specialized and grouped together to form glands, organs, systems, muscles, and bones that are perfectly integrated with each other and provide the incredible result we know as life. This is all the natural result of evolution. Ironically, it’s the intelligence we also gained through evolution that gives us the ability to manipulate, for better or worse, this delicate balance that nature has so cleverly created.

Are We Victims of Our Own Intelligence?

As humans, we have the consciousness to philosophize about life and reflect on emotion. As a result, we all want to live long and happy lives. While science has enabled us to manipulate the odds in our favor in some respects, it’s reduced our odds in others. After all, science is invention and discovery that results from human intelligence, and human intelligence is not immune to mistakes, greed, or corruption.
