A new study in The American Journal of Clinical Nutrition has found that having higher levels of Omega-3 fatty acids in the blood predicts a lower mortality rate in people over the age of 65 years. And suggests a potential increase in lifespan of up to 5 years – compared to people with low levels of Omega 3.

Omega-3 is a type of polyunsaturated fatty acid which contributes to forming healthy cell membranes. It is considered “essential” since the body cannot make it on its own.

Previous research has confirmed that Omega-3 provides not just energy, but is vital for the body’s cardiovascular (heart and blood circulation), pulmonary (lungs), immune, and endocrine systems. It is also very important for foetal development.

Omega-3 is an anti-inflammatory nutrient occurring in food oils from certain types of fish, seeds such as flax and chia, walnuts, soybeans, seaweed and marine algae.

Combine Omega-3 with other health-protective nutrients

Of course, it is likely that people who ensure a healthy Omega-3 intake are also more likely to follow other health advice – like eating several portions of fruits and vegetables a day.

Indeed, Imperial College London and the American Cancer Society both recommend oily fish 2-3 times a week alongside 9 -10 portions of fruit and veg a day! Since this is a challenge for most people, many take health supplements to bridge the gap.

The comprehensive nutritional health supplement NutriShield was designed by Dr Paul Clayton (former Chair of the Forum on Food and Health at the Royal Society of Medicine). It contains Omega-3, well-researched plant nutrients like curcumin, green tea and grapeseed extracts, plus a full range of vitamins and minerals. There are versions for under and over age 50.
