Omega-3 fish oilis vey beneficial for heart patients. Diet rich in omega-3 fatty acids keeps the DNA of patients with coronary heart disease from unraveling. Regular intake of fish oil in form of diet supplement after stroke can reduce the risk of sequential heat stroke and death due to coronary heart disease. Scholars found the mechanism through which omega-3 fatty acid worked and provide benefits to the heart.
They took study by focusing on length of telomere which is the length of protective caps that are present on the ends of chromosomesthat carry DNA. When these protective caps get short it can cause premature aging and cancer also. Researchers measured the length of telomere in stroke patients to find any affiliation between omega-3 fatty acids level and change in length of telomere over time.
They found that increased amount of omega-3 fish oil in the blood can decrease the rate of biological aging process. Patients with high level of omega-3 fatty acids had longest telomeres while patients with low level of omega-3 fatty acids had shorter telomeres. Fish oil is primary source of omega-3 fatty acids. Omega-3 is also found in leafy green vegetables, walnuts and flax seed oils.
Omega-3 fish oil counter-checks oxidative stress which is caused due to cell damaging chemical reaction and it can make telomeres short. Fish oils can increase the production of telomeres that is an enzyme which gives length and repair the short telomeres.
