The link between diet and chronic disease has long been recognized, and as a result, nutrition education has become an integral part of personal development for building knowledge and skills to adopt and maintain healthy lifelong behaviors. The focus on adverse food reactions in the Western society is relatively non-existent and yet, the majority of us, if not all of us, have them.

What are telomeres?

A telomere is a cap on the end of a chromosome.  The discovery of telomeres was so important to science and medicine that the 2009 Nobel Prize was awarded to three scientists who made the initial discoveries in the field1.  To understand why telomeres are critical, it helps to have a little background in genetics.


What does a telomere test measure?

The telomere test is a blood test.  While most of your blood cells don’t contain DNA, your white blood cells, or leukocytes, do contain DNA.  These are the cells that are used to measure your telomere length1.  The measurement you receive is called your leukocyte telomere length, or LTL.  The LTL is an average of the length of the telomeres in the cells from your blood sample; it’s been shown in studies to be highly correlated with the length of telomeres measured in other tissues of the body2.


How can I protect my telomeres from shortening?

Having learned that the shortening of telomeres is thought to be a major contributor to aging, you’re likely to be wondering how you can keep your telomeres as long as possible.  And while there are some factors associated with telomere length that you can’t control, such as your gender1, how long your parents lived2, and how difficult your childhood was3, there are quite a few things you can do to help keep your telomeres long and healthy.


What factors affect telomere length?

It’s been said that telomere length “captures the interplay between genetics, life experiences, and psychosocial and behavioral factors”1.  In other words, your telomere length can be affected by nearly everything in your life.


How is Telomere length measured?

Measurement of telomere length is done on white blood cells, or leukocytes.  These cells are used because they’re the only blood cells that contain DNA.  Isolation of the DNA from these cells allows the measurement of leukocyte telomere length, or LTL.  Studies have shown that LTL is correlated with telomere length in other body tissues1, making the measurement of LTL a reliable method of determining overall average telomere length.


In order to measure LTL, the leukocytes are first collected, usually from the blood.  This may involve venipuncture (collection of blood from a vein through a needle) or a fingertip prick, from which blood is collected in a small tube or a blood spot collected on special paper2.  In some tests, a cheek swab is used3.


Food Intolerance & Disease

Submitted by ggs on Mon, 11/17/2014 - 11:41

Food intolerance induces inflammation and the excessive generation of toxic free radicals and immune chemical, increasing the occurrence of metabolic, chronic and degenerative diseases.

In contrast with “True” allergy, whereby a few molecules of peanut may, for example, induce anaphylaxis, the sheer magnitude of exposures to intoleragenic foods, despite its less dramatic flare (pun intended), causes greater morbidity and mortality.

Allergy vs. Intolerance

The etiology of true allergy became known in 1967. It was soon determined that allergens (allergy generators) were taken up by antigen presenting cells and presented to T lymphocytes in a similar fashion as peptide products of pathogenic microorganisms.
