They do not contain information essential for cell life, but they have a <strong>protective function<\/strong>. Made up of repeated DNA sequences, telomeres act as a sort of <em>cap<\/em> and help make the chromosome&#8217;s <strong>DNA<\/strong> <strong>more stable<\/strong> and <strong>prevent the accumulation of damage<\/strong> to it. Each time DNA replicates, in fact, the point of the helix to which the enzyme responsible for replication attaches cannot be copied and is lost, resulting in a slight <strong>shortening<\/strong> of the sequence. The regions to which the enzyme attaches are precisely the telomeres, which undergo progressive shortening <strong>with each cell cycle<\/strong>.    <\/p>\n<div class=\"container-product-box\"><div class=\"product-box\"> <div class=\"badge\">SOLONGEVITY SHOP<\/div>    <div class=\"product-image\">        <img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0765\/8015\/9763\/files\/1.jpg?v=1688391005\" alt=\"CellFasting.

At this point, the cell <strong>no longer divides<\/strong> and enters a phase of <strong>senescence<\/strong>, which may or may not result in <strong>cell death<\/strong> (apoptosis). This sort of programmed cell death is essential to avoid replication errors that could be harmful.  <\/p>\n<p>The length<strong> of telomeres<\/strong> is affected by numerous external factors, such as <strong>infections<\/strong> or <strong>air pollution<\/strong>. Some recent studies have in fact shown that the telomeres of people exposed to pollution undergo temporary shortening in correspondence with peaks of <strong>fine particulate matter<\/strong>. <\/p>\n<h3>What is the relationship between telomere length and aging?<\/h3>\n<p><strong>Telomere length<\/strong> is associated with the life cycle of the cell, which is why it is considered a valid <strong>indicator of cellular aging<\/strong>. However, generalizing this concept to the whole organism to calculate biological age (that is, the measure of the organism&#8217;s aging) could be inaccurate. Usually, in fact, the telomere lengths of the immune system cells present in the blood are measured, but these are involved in many processes, for example inflammation, which affect cell replication and therefore the estimate of cellular age. Telomere length, therefore, can give an indication of the<strong> general health<\/strong> of an organism at a given moment, but <strong>does not seem to be a reliable method for calculating biological age<\/strong>, as is commonly believed.   <\/p>\n<h3>The role of lifestyle<\/h3>\n<p>With a <strong>healthy lifestyle<\/strong>, telomere length in cells seems to improve, a confirmation (if any were needed) that both <strong>physical activity<\/strong> and <strong>diet<\/strong> play an important role in health. In particular, the <strong>Mediterranean diet<\/strong>, rich in plant-based foods \u2014 such as whole grains, vegetables, legumes, fruit, spices and olive oil \u2014 contains <strong>antioxidants<\/strong> that may have a protective effect against cell damage linked to inflammatory states and on telomeres. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Telomeres are the end parts of chromosomes and protect DNA.
