Omega-3 fatty acids from fish oil, may aid healing after heart attack

Giving heart attack patients a high dose of omega-3 fatty acids from fish oil, daily for six months after a heart attack improved the function of the heart and reduced scarring in the undamaged muscle, according to new research.

The heart's shape and function can be altered after a heart attack, a condition known as post-heart attack remodeling and it is linked with poor patient outcomes and could lead to heart failure. Therapies that can improve healing of the heart or prevent adverse remodeling remain scarce.

'Hacking nerves can control disease'

Controlling human nerve cells with electricity could treat a range of diseases including arthritis, asthma and diabetes, a new company says.

Galvani Bioelectronics hopes to bring a new treatment based on the technique before regulators within seven years.

GlaxoSmithKline and Verily, formerly Google, Life Sciences, are behind it, according to BBC.

Animal experiments have attached tiny silicone cuffs, containing electrodes, around a nerve and then used a power supply to control the nerve's messages.

Extreme sleep durations may affect brain health in later life

A new research study, shows an association between midlife and later life sleeping habits with memory; and links extreme sleep durations to worse memory in later life. The study suggests that extreme changes in sleep duration from middle age to older age may also worsen memory function according to Science daily.

"Sleep Duration In Midlife and Later Life In Relation to Cognition: The Nurses' Health Study," led by Elizabeth Devore, found that women who slept five or fewer hours, or nine or more hours per day, either in midlife or later life, had worse memory, equivalent to nearly two additional years of age, than those sleeping seven hours per day. Women whose sleep duration changed by greater than two hours per day over time had worse memory than women with no change in sleep duration.

Amount, types of fat we eat affect health, risk of disease

Healthy adults should consume between 20 percent and 35 percent of their calories from dietary fat, increase their consumption of omega-3 fatty acids, and limit their intake of saturated and trans fats, according to an updated position paper from the Academy of Nutrition and Dietetics

The position paper "Dietary Fatty Acids for Healthy Adults" has been published. The position paper provides guidance for registered dietitian nutritionists and dietetic technicians, registered to translate research on fat and fatty acids into practical dietary recommendations for consumers.

Can pomegranates really add years to your life - and fight cancer?

They're the trendy fruit that are the latest must-have ingredient for salads and juices, even cocktails. But could pomegranates help you live longer, too?

This is down to chemicals called ellagitannins, which are found in high levels in the fruit.

Our gut bacteria turn these chemicals into a compound called urolithin A, which helps keep the mitochondria (tiny battery packs that power the body’s cells) charged.

In lab studies, worms and mice given urolithin A lived longer and ran further . Some experts warn it’s too early to say the same would happen with humans.

But pomegranates have previously been credited with an array of health benefits, including fighting cancer.
