Aging is an inevitable process in human and telomere (ie: specialized structures at the end of the chromosomes to protect the loss of human’s genetic data during cell division) plays important part in regulating ageing process. The length of telomere shortens with age and the progressive shortening of telomeres may affect the health and quality of life of an individual negatively with increased risks of disease development and poor survival rate [1].

Nonetheless, healthier dietary intake with high consumption of fruits and vegetables and balanced lifestyle can help to slow down the ageing process. In fact, dietary carotenoids have shown beneficial effects in relation to ageing associated adverse health effects as demonstrated in the studies below:

Study Significant Findings Reference
Increases Telomere Length
Association between leukocyte telomere length and serum carotenoid in US adults

Plasma blood level of alpha-carotene, beta-carotene and beta-cryptoxanthin were significantly associated with longer telomeres.

When comparing to the lowest carotenoid (alpha-carotene, beta-carotene and beta-cryptoxanthin) quartiles, the telomere length increased from 5-8% in the highest carotenoid quartiles cohort
