High Omega-3 is linked to 5 years longer lifespan
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.
This article was written by Colin Rose, a Senior Associate Member of the Royal Society of Medicine, who has been writing on health science for over 30 years. He is also the founder and Director of Research and Innovation of Uni-Vite Healthcare.
A highly effective anti-inflammatory nutrient
The National Institutes of Health in the USA cites numerous previous studies that indicate that diets high in Omega-3s are linked to many positive health outcomes. They include:
♦ lower rates of cancer
♦ a reduced risk of Alzheimer’s disease
♦ a reduction in the symptoms of rheumatoid and osteo-arthritis.
All these diseases have inflammation as a major contributory cause.
Although studies have found no direct effect on lowering heart disease risk, Omega-3 does slow the development of plaque in arteries.
New Omega-3 study on 2,240 people over 11 years
In the new study, researchers tracked 2,240 participants over 11 years and recorded Omega-3 levels in the participants’ blood.
Study author Dr Aleix Sala-Vila concluded that:
“Having higher levels of these fatty acids in the blood, as a result of regularly including oily fish in the diet, increases life expectancy by almost 5 years.”
His co-author Dr William S. Harris, commenting to Medical News Today, added:
“Knowing a person’s omega-3 index is just as — if not more — important than knowing a person’s cholesterol level or blood pressure, and ‘fixing’ the omega-3 index is much easier (and cheaper and safer) than treating all those other risk factors.
“Eat more fish and/or take an omega-3 supplement.”
Foods and supplements high in Omega-3
Top oily fish for Omega-3 content per typical serving.
- Mackerel (5,134 mg in 100g/3.5oz)
- Herring eg. kippers (2,366 mg in 100g/3.5oz)
- Salmon (2,260 mg in 100g/3.5oz)
- Sardines (1,480 mg in 100g/3.5oz)
- Caviar (1,086 mg per tablespoon/14.3g)
- Anchovies (951 mg per 45g/2oz can)
- Oysters (435 mg in 7 oysters/100g/3.5oz)
SEEDS AND NUTS
Top non-fish food sources for Omega-3 content per typical serving.
- Flaxseed oil (7,260 mg per tablespoon/13.6g)
- Chia seeds (5,060 mg per 28g/1oz)
- Walnuts (2,570 mg per 28g/1oz or 14 walnut halves)
- Flaxseeds (2,350 mg per tablespoon/10.3g)
- Soybeans (1,443 mg per 100g/3.5oz)
- Rapeseed (canola) oil (1,406 mg per tablespoon/13.6g)
Supplement capsules of oils from fish (including cod liver, krill), flaxseeds, algae. Check for Omega-3 content.
- NutriShield Premium and NutriShield Essentials Standard include 1 daily capsule of purified, sustainably sourced, high-triglyceride fish oil (1,000 mg) with 650 mg of Omega 3 as 330mg EPA and 220mg DHA
- NutriShield Essentials Vege includes 1 daily capsule of 1,000 mg flaxseed oil with 500mg of Omega-3 as alpha-linolenic acid
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.
Conclusion – Ensure high Omega-3 status
On top of eating oily fish often, plus flaxseeds, chia seeds and walnuts, taking daily Omega-3 supplements is a convenient way to ensure a high Omega-3 status.
Dr Paul Clayton designed NutriShield as a comprehensive health supplement with OPTIMUM levels of 43 essential nutrients including Omega-3, polyphenols and flavonoids from fruits, vegetables and other plants, betaine and green tea.
