Scientists say that omega-3 fatty acids in fish oil can help people with heart disease live longer. But until now, no one knew why omega-3 oils are so beneficial. This is what coronary artery disease looks like. Plaque builds up inside the coronary arteries and blocks the flow of blood to the heart. Coronary artery disease is one of the leading causes of death worldwide. Numerous studies show that cold-water fish –salmon, tuna, and other oily fish — contain omega-3 fatty acids that can decrease the risk of this disease. But no one knew exactly why.

Dr. Ramin Farzaneh-Far at the University of California conducted a study to see if there might be a link between cellular aging and omega-3 acids. “The main result from our study is that patients with high levels of omega-3 fish oil in the blood appear to have a slowing of the biological aging process,” Dr. Farzaneh-Far said.

Protective caps on the ends of chromosomes called telomeres, shown here in red, contain genetic material. As they shorten, cells age. Dr. Farzaneh-Far and colleagues measured the length of telomeres in blood cells of 600 heart patients. They wanted to see if there was any association between the levels of omega-3 fatty acids and the change in telomere length over a period of time.

“Patients with the highest levels of omega-3 fish oils were found to display the slowest decrease in telomere length, whereas those with the lowest levels of omega-3 fish oils in the blood had the fastest rate of telomere shortening, suggesting that these patients were aging faster than those with the higher fish oil levels in their blood,” Dr. Farzaneh-Far explained. Dr. Farzaneh-Far says the results of his study support the American Heart Association’s recommendation that heart disease patients with coronary artery disease have at least one gram per day of omega-3 fish oil.

Researchers used to think that only regular exercise and managing stress could keep telomeres healthy. But either eating fatty fish or taking omega-3 supplements can also be effective. At the most, Dr. Michael Roizen of the Cleveland Clinic says it will not hurt. “It’s a risk-free way of potentially extending lifespan and reducing disability,” he said. And omega-3 acids are not just for heart disease patients. Omega-3’s have been associated with easing joint inflammation, slowing memory decline, and reducing macular degeneration, the most common cause of blindness in the elderly. (VOA/JC)

Eating fruits is one of the most satisfying ways to tackle sweet-tooth cravings while meeting your nutritional needs. Despite many studies and research on fruit consumption in diabetes, there are a lot of speculations on the right kind of fruit consumption and its relation to blood sugar levels.

Eating seasonal and locally available fruit has many health benefits ranging from reducing sugar and inflammation levels to fighting high blood pressure -- thanks to their abundant vitamins and mineral presence! They are a powerhouse of antioxidants like vitamins A, B, C, E, and minerals like iron, calcium, magnesium, and fiber.

The fruits listed below are not just diabetic-friendly but are loaded with fiber and water content which can slow down the sugar spikes and sugar absorption rate. Apples are not just nutritious and filling; According to a study, they are significantly associated with a lower risk of type 2 diabetes if consumed in moderation. Turns out there is a truth in the old saying, "An apple a day keeps the doctor away", after all!

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body and left her with "permanent stretch marks". For her role in the film, based on the life of late Tamil Nadu Chief Minister and former actress J. Jayalalithaa, Kangana had to gain 20kg and undergo major physical transformation several times.

She took to Instagram to share her experience, detailing that doing all that over the six months period left her with "permanent stretch marks". "Gaining 20 kgs in 6 months and loosing it all within 6 months that too in my thirties messed up many things in my bodya I also have permanent stretch marks as well but art comes to life with a price and more often than not price is the artist him/herself," she wrote.

"Thalaivii" showcases the varied aspects of Jayalalithaa's life, tracing her journey as an actress at a young age to becoming the face of Tamil cinema, as well as the rise of the revolutionary leader who changed the course of the state's politics. Talking about her upcoming works, Kangana currently has 'Dhaakad'.

She is also shooting for her next 'Tejas', where she plays a fighter pilot. The Indian Air Force was the first of the country's defence forces to induct women into combat roles in 2016. The film takes inspiration from the landmark event. 'Tejas' is directed by debutant Sarvesh Mewara. The film will be RSVP's second film which pays a tribute to the Indian military after the immensely successful film "Uri: The Surgical Strike" which was released in January 2019. (IANS/ MBI)
