Fish oil supplements improves muscle function in older women

November 17, 2016

London, Nov 17: Taking fish oil supplements could improve muscle function in older women and potentially increase their quality of life, according to a latest study.

fishoilIn the study led by the Universities of Glasgow and Aberdeen published today in The American Journal of Clinical Nutrition, scientists have found that supplementing the diet of older women with 3g of fish oil (omega-3) results in greater increase (when compared to a 3g of safflower oil placebo) in their muscle function when combined with resistance exercise training over 18 weeks.

Before and after the exercise training programme researchers measured muscle size, using MRI, and muscle function, using a testing dynamometer, and calculated muscle quality (force produced relative to muscle size).

As expected, the resistance exercise training increased muscle size, function and quality in all groups of participants. In men, who were taking the fish oil supplements there were no extra gains in muscle function or size observed over the 18-week intervention period.

However, in women, those taking fish oil their muscle function, but not size, increased to a greater extent compared to those in the placebo group.

In women in the placebo group, exercise training resulted in an average strength increase of 16 per cent, however, when the exercises were combined with an intake of fish oil that improvement increased to an average of 34 per cent.

Stuart Gray from the University of Glasgow's Institute of Cardiovascular and Medical Sciences (formerly of the University of Aberdeen, where much of the study was completed) said: "These findings provide important information for nutritional guidelines in older people where policy makers may want to consider

recommendations for fish oil supplements to be consumed by older women. Why men do not see the same benefit as women is important to understand and the underlying mechanisms need to be studied."

Researchers highlighted the fact that this greater increase in muscle function noted in women was independent of any changes in muscle size with fish oil, such that it was muscle quality rather than size was improved.

The primary function of skeletal muscle is to carry out daily tasks, such as rising from a chair or getting on a bus, tasks often referred to as functional abilities.

However, both size and function progressively decrease as a normal part of healthy ageing. This decrease in function can result in a reduction in quality of life, increased falls risk and loss of independence.

Gray added: "With the percentage of people aged over 65 predicted to rise from 17 per cent, of the total population in 2010, to 23 per cent in 2035, it is crucial to develop effective treatments for the age-related loss of muscle function.

"Findings of a benefit in women are particularly important as women tend to live around four years longer than men and cross the "disability threshold", where functional abilities are lost, 10 years earlier than men.

The study, 'Sex-differences in the effect of fish oil supplementation on the adaptive response to resistance exercise training in older people: a randomised control trial' is published in The American Journal of Clinical Nutrition.

Washington, Jul 9: Ayurvedic practitioners and researchers in India and the US are planning to initiate joint clinical trials for Ayurveda formulations against the novel coronavirus, the Indian envoy here has said.

In a virtual interaction with a group of eminent Indian-American scientists, academicians, and doctors on Wednesday, Indian Ambassador to the US Taranjit Singh Sandhu said the vast network of institutional engagements have brought scientific communities between the two countries together in the fight against Covid-19.

 “Our Institutions have also been collaborating to promote Ayurveda through joint research, teaching and training programs. Ayurvedic practitioners and researchers in both the countries are planning to initiate joint clinical trials of Ayurvedic formulations against Covid-19,” Sandhu said.

“Our scientists have been exchanging knowledge and research resources on this front,” he said.

The Indo-US Science Technology Forum (IUSSTF) has always been instrumental in promoting excellence in science, technology, and innovation through collaborative activities.

To address Covid-19-related challenges, the IUSSTF had given a call to support joint research and start-up engagements. A large number of proposals are being reviewed on fast track mode by the experts on both the sides, he said.

“Indian pharmaceutical companies are global leaders in producing affordable low-cost medicines and vaccines and will play an important role in the fight against this pandemic,” Sandhu said.

According to the ambassador, there are at least three ongoing collaborations between Indian vaccine companies with US-based institutions.

These collaborations would be beneficial not just to India and the US, but also for the billions who would need to be vaccinated against Covid-19 across the world, he noted.

Asserting that innovation will be the key driver in pandemic response and recovery, he said tech-companies and start-ups have already begun to take the lead in this direction.

"Telemedicine and telehealth will evolve as will other digital platforms across sectors," he said.

Noting that there has been a longstanding collaboration between India and the US in the health sector, he said scientists have been working together in several programs to understand important diseases at the basic and clinical level.

Many such programs have been focused on translational research to develop new therapeutics and diagnostics.

There are over 200 ongoing NIH funded projects in India involving 20 institutions from NIH network and several eminent institutions in India engaged in a wide spectrum of research areas to create health care solutions, the senior diplomat said.

The collaboration under Vaccine Action Program (VAP) resulted in the development of ROTAVAC vaccine against rotavirus which causes severe diarrhea in children.

The vaccine was developed by an Indian company (Bharat Biotech) at an affordable cost. It has been commercialised and introduced in the Expanded Program on Immunisation.

Development of many other vaccines such as TB, Influenza, Chikungunya are also in progress under the VAP, he said.

 “As I speak, the VAP meeting is in progress where experts from both countries are deeply engaged in technical discussions to expedite development of Covid-19 vaccine,” Sandhu said in his remarks.

During the interaction, the eminent experts appreciated India's handling of the Covid-19 pandemic and offered their valuable suggestions and best practices in this regard.

They shared their ideas on deepening the knowledge partnership between India and the US.

The experts who took part in the interaction, were drawn from wide-ranging fields including artificial intelligence, quantum information science, biomedical engineering, robotics, mechanical engineering, earth and ocean science, virology, physics, astrophysics, and health sciences.

Prominent among those who attended the virtual interaction were Subhash Kak Regents Professor at Oklahoma State University, Dr Vijay Kuchroo, Samuel L Wasserstrom Professor of Neurology at Harvard Medical School, Dr Ashish M Kamat, Professor of Urology at MD Anderson Cancer Center, Ashutosh Chilkoti, Alan L Kaganov Professor of Biomedical Engineering and Chair of the Department of Biomedical Engineering at Duke University; and Prof Manu Prakash, a professor in Department of Bioengineering at Sandford University, among others.

Washington D.C., Jan 5: After a woman filed a lawsuit against a diet soda company, the California court has declared that the beverage does not promise to help buyers in losing weight.

The woman had gulped down the drink for over a decade but did not lose inches as a result.

The three-judge panel declared during the hearing: "The prevalent understanding of the term in (the marketplace) is that the 'diet' version of a soft drink has fewer calories than its 'regular' counterpart."

However, the members of the US 9th circuit court have felt that the consumers tend to make out something of their own that is unreasonable and eventually hamper the reputation of brands through a deceptive allegation, reports Fox News.

The response was due to a misleading case filed against Diet Dr Pepper by Shana Becerra from Santa Rosa, California. Shana claimed that she has been addictively purchasing the low-calorie beverage for the past 13 years hoping for losing some fat but failed to lose even a single inch.

The woman also stated that the attractive and fit models misled her into believing that drink will help her in perfecting her body like them.

However, the court's decision was that advertisements are for representational purposes only. "Cannot be reasonably understood to convey any specific meaning at all," as written by Judge Jay Bybee.

Shana had last week made such allegation against Diet coke as well where the court came to a similar verdict. She claimed that she had found various studies where it is evident that the artificial sweetener aspartame used in diet beverages actually boosts weight gain.

But the artificial sweetener is approved in by the concerned administrative department and thus is used in most American drinks.

Washington D.C., Jan 3: A new study has found out that diet significantly affects the mental health and well being of an individual.

The study was published in the journal European Neuropsychopharmacology.

"We have found that there is increasing evidence of a link between a poor diet and the worsening of mood disorders, including anxiety and depression. However, many common beliefs about the health effects of certain foods are not supported by solid evidence," said the lead researcher, Professor Suzanne Dickson.

According to the researchers, the link between diet and mental health can be firmly established in certain cases like that of the ability of a ketogenic diet being helpful for children with epilepsy and the impact of vitamin B12 deficiency on poor memory, depression and fatigue.

"With individual conditions, we often found very mixed evidence. With ADHD for example, we can see an increase in the quantity of refined sugar in the diet seems to increase ADHD and hyperactivity, whereas eating more fresh fruit and vegetables seems to protect against these conditions," said Dickson

But there are comparatively few studies, and many of them don't last long enough to show long-term effects," added Dickson.

The study further concludes that some food items can be associated with treatment and the betterment of certain mental health conditions.
