When it comes to omega-3 fatty acids, like the kind found in fish oil, the big question has been whether they really help prevent heart disease.
Findings up to now have been frustratingly mixed, but a new comprehensive analysis of international studies suggests a clearer answer: Regularly eating fish, nuts and other omega-3-rich foods are associated with a significantly lower risk of dying from a fatal heart attack.
“Our results lend support to the importance of fish and omega-3 consumption as part of a healthy diet,” senior study author Dariush Mozaffarian, dean of the Friedman School of Nutrition Science and Policy at Tufts University, said in a prepared statement.
The consumption of omega-3 and medium chain triglycerides (MCTs) can promote brain health and delay the onset and severity of degenerative diseases such as dementia, according to new research by a Japanese anti-ageing expert.
Among the many nutrients studied by scientists for the past two decades, omega-3 and MCTs are among the most promising in preventing and mitigating age-related diseases, especially dementia, says Prof Takuji Shirasawa. One of Japan’s top specialists in preventive medicine for ageing, Prof Shirasawa shared his findings at the Nutrition Society of Malaysia’s 31st Annual Scientific Conference held in Kuala Lumpur recently.
A type of fat found in cell membranes, omega-3 is made in our bodies but at a very slow pace. As such, omega-3 is mostly obtained from our diet. Oily fish such as tuna, salmon and mackerel are said to have high levels of omega-3.
“Omega-3 has been largely demonstrated to be protective of the cardiovascular system. As such, omega-3 plays a key role in the prevention, delay and mitigation of age-related diseases,” said Prof Shirasawa.
