Boy or Girl? Telomeres have been likened to the plastic tips of a shoelace. When they get damaged, the shoelaces our chromosomes become frayed and can no longer do their job well.
Telomeres are shortened every time our cells replicate and naturally shorten as we age. They can also be shortened by an unhealthy lifestyle : poor diet, lack of exercise and sleep, smoking, obesity and stress. Longer telomeres have been associated with longer lives. The September issue of The Lancet featured one of the first studies to determine the effects of lifestyle on telomere length.
Researchers Dean Ornish, MD, Elizabeth Blackburn, PhD, and colleagues reported that a comprehensive lifestyle shift resulted in elongated telomeres in men with low-risk prostate cancer. The lifestyle changes included a low-fat, plant-based diet, moderate daily exercise, stress management and social support. This intervention group increased telomere length by 10 percent while those in the control group had a 3 percent reduction in telomere length after five years.
Nutrition can have a significant impact on the length of telomeres. In The Telomere Effect by Elissa Epel and Elizabeth Blackburn, the researchers recommend a plant-based approach that includes fresh vegetables, fruit, whole grains, nuts and legumes.
Other nutrient-rich foods that are high in antioxidants such as seaweed and green tea have also been linked with longer telomeres and increased lifespan.
An easy addition to any salad or smoothie, flax is a great source of omega-3s, which are important for both preventing inflammation and building cell membranes throughout the body. Research shows that omega-3s can prevent telomeres from shortening too quickly.

Join the Fight. One day it may be possible to target muscle stem cells in a patient with Duchenne muscular dystrophy, for example, to extend their telomeres. There are also implications for treating conditions of aging, such as diabetes and heart disease. This has really opened the doors to consider all types of potential uses of this therapy. In June last year, Medical News Today reported on a study led by the University of California-San Francisco, in which researchers claim — contrary to other studies — longer telomeres are associated with an increased risk of brain cancer.
Achondroplasia is a rare genetic disorder that causes short stature and bowed legs as a result of a genetic mutation. Learn more. In a new study, researchers found that people with a particular variant of a gene that produces oxytocin tended to follow more people on Instagram. The mutation can lead to many health conditions. Niemann-Pick disease is a rare genetic disorder that renders the body incapable of metabolizing cholesterol and other lipids inside cells.
