WHAT EFFECT DO SHORTER TELOMERES HAVE ON HEALTH?
There are a number of studies that have linked chronic diseases such as cardiovascular disease to shorter telomeres. So it was no surprise when researchers determined that type-2 diabetes was also linked to shorter telomeres. However, the story of diabetes is not entirely clear, given that there are not enough studies at the moment to determine if type-1 diabetes may also be linked to shorter telomeres. Therefore, questions regarding diabetes and telomere length remain. In particular, can telomere length induce diabetes or is diabetes causing telomeres to shorten? This question is partially addressed by a group of researchers who wondered whether sugar-sweetened beverages in our diet could lead to the shortening of our telomeres (American Journal of Public Health, doi:10.2105/AJPH.2014.302151). 
A STUDY ON SODA VS. FRUIT JUICE FOR TELOMERE LENGTH
Specifically, a research collaboration between different laboratories from UC San Francisco, UC Berkeley, and Stanford University tested whether the telomere lengths of cells from our blood could be linked to the regular consumption of sweetened beverages. The researchers examined the regular consumption of sweetened beverages by healthy individuals with no history of diabetes or cardiovascular diseases. They compared the telomere length of cells taken from the blood of healthy individuals who consumed either sugar-sweetened soda, 100% fruit juice, or diet sodas regularly. Interestingly, the researchers observed an association between shorter telomeres with sugar-sweetened soda-drinking individuals, and longer telomeres were linked to 100% fruit juice-drinking individuals. Indicating that the type of sugar may play a role in the development of the disease. 
What about Diet Soda?
In addition, the researchers found no links to telomeres length and diet soda consumption. The authors concluded that regular sugar-sweetened soda consumption might influence the development of diseases (such as diabetes) through an accelerated aging mechanism.
