People with higher levels of Omega-3 have lower risk of dying

Posted on by

A 16-year-old study of older adults  has revealed that those with higher blood levels of omega-3 polyunsaturated acids had a lower risk of dying.

Omega-3 fatty acids are abundant in oily fish, such as salmon, sardines and mackerel, have already  been linked to a number of health benefits, including a lower risk of cardiovascular disease.

The study included 2,692 US men and women aged 65 years or older who took part in the Cardiovascular Health Study between 1989 and 1993.

Researchers questioned them about their eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) intake. Blood samples obtained during 1992-1993 were also analysed for plasma phospholipid EPA, DHA and docosapentaenoic acid (DPA).

Over sixteen years of follow-up, 1,625 deaths occurred, including 359 caused by coronary heart disease (CHD) and 130 resulting from stroke. But the men and women whose total omega-3 fatty acids were among the top one-fifth of participants had a 27% lower risk of dying than those whose levels were among the lowest fifth.

When omega-3 fatty acids were individually analysed, those among the top fifth of EPA, DPA and DHA levels were found to have a 17%, 23% and 20% lower risk. The risk of dying of heart disease was 35% less among those whose total omega-3 levels were highest, and arrhythmic cardiac deaths were lowered by 48%. On average, having an omega-3 fatty acid level among the top fifth conferred 2.2 extra years of life in comparison with whose level was lowest.

When the relationship between omega-3 fatty acid intake and plasma levels was examined, the largest effect was seen with an intake of up to 400 milligrams per day.

Research lead author, Professor Dariush Mozaffarian, of the Harvard School of Public Health said: “The findings suggest that the biggest bang-for-your-buck is for going from no intake to modest intake, or about two servings of fatty fish per week. They support the importance of adequate blood omega-3 levels for cardiovascular health, and suggest that later in life these benefits could actually extend the years of remaining life.”

Good fats help brain decline in older people, new study reveals

Tokyo: The decline of cognitive function in older people is less in those who take a combination supplement, containing, food fats, a new study from Japan has revealed.
The findings of a three year study that evaluated the effects of capsules containing 1,182 milligrams purified fish oils containing 290 milligrams eicosapentaenoic acid (EPA) and 203 milligrams docosahexaenoic acid (DHA); 84 milligrams lycopene from tomato and 240 milligrams Ginkgo biloba extract.  The pill was given to 41 participants aged 65 and older,  daily for three years.

Tests of cognitive function, including attention, memory, language and reasoning skills, were administered at the beginning and end of the study. Blood samples collected at the initial examination were analyzed for apolipoprotein E (APOE) genotype and other factors. 
The authors of the study said:  “An increasing number of studies in cell lines, targeted replacement rodents, and human volunteers indicate higher oxidative stress and a more pro-inflammatory state associated with the apolipoprotein E4 allele (APOE4).”
Although memory scores improved in both groups, the increase was larger in those who received the supplements compared to the controls. Language ability and attention declined in those who did not receive the supplements, while remaining stable in supplemented participants. When test scores were evaluated as a whole, a significant improvement occurred only in supplemented subjects. Improvement was noted in both supplemented APOE4 carriers and noncarriers; however, the benefit was greater in those positive for APOE4.
Mechanisms for EPA and DHA in maintaining cognitive function are well known, and include the fatty acids’ anti-inflammatory and antioxidant properties. However, although omega-3 fatty acids have an antioxidant effect, they are also subject to lipid peroxidation, therefore, combining them with compounds that have antioxidant properties such as lycopene could improve their benefits.
“When just one of these agents or nutrients is used by an elderly person, its effect on cognitive function is not enough to prevent aging decline, at least not with the usual dosage in human trial studies,” the authors remark. “When these agents or nutrients are used in combination, they may cover the vulnerability of other agents and synergistically potentiate their respective antioxidant properties, which might then be effective for the improvement of cognitive function. Additionally, this may decrease the oxidative stress associated with the E4 allele and improve cognitive function among APOE4 carriers.”

The real detox

Posted on by

Yogatastic Don’t spend loads of money on detox packs or string yourself out on a disgusting syrup, juice and pepper concoction – commit to something which actually works…

Every year we say we will stop eating when we feel full, or have one or two fewer glasses of wine but it never works.Well now the forced excess is all over and it’s time for punishing ourselves with the latest detox and weight loss fad. Or is it?

Losing that bloated sinking feeling and getting yourself back on track for 2011 could be much simpler than you realise.

We know the celebrities all endorse various detox/weight loss plans and we understand why. They are under a great amount of pressure to look good and above all, be the slimmest they can be, which prompts drastic measures in even the least neurotic and anxious of people. For those of us living our mundane (cough) everyday lives, such drastic action is not required: a few little tweaks can make all the difference.

Here are six quick tips to banish that ‘jabba the hutt’ feeling:

1. Make sure you get enough sleep. When you are tired your body wants the high energy, quick fix food which is very bad news for your blood sugar level and waistline. Tired people are also less likely to have the energy to exercise. Tired people always look older: perhaps the most effective inducement to get enough shut-eye. Need any more reasons?!

2. As above, high energy/sugar food is very bad news for you (unless you are a super-duper fit athlete who burns a gazillion calories a day). Eating high sugar foods sends you up into the stratosphere for about 20 minutes until you crash back down to earth and into the biscuit cupboard. We don’t need to give it up completely, just reduce portion size and be careful not to eat your treat after dinner as those calories will be going nowhere fast.

3. Raise your heart rate for at least 15 minutes a day. We all have some lonely exercise equipment or one of the many computer console exercise programs to hand for a quick endorphin boost, so requires no extra spenditure.  It gives you a little extra energy to go about your business and you don’t have to trek to the gym to spend time with other sweaty people. Yuck.

4. Alcohol. We’re sorry to have to say this but if you want to feel better within a week, any delicious alcohol-based beverage is out. Alcohol is full of sugar. Wine is quite probably the healthiest of all the marketed beverages but still, as above, we know it is hard to restrict ourselves to just the one glass. So we advocate cutting it out for just a little while. Your liver will give thanks and you will very soon notice you are much less sluggish with better skin.

5. Fruit and veg. You may have heard the news, you may not have done, but here it is; we do not have to eat 5 portions of fruit or veg a day. Of course it is advisable to eat as much as you can without stressing or obsessing if for no other reason that by eating something green, you are not eating a big cake or pork pie. Fruit is nice as well. You may have forgotten how nice it is with all those sugar laden treats out there but if you manage to cut back your sugar intake you will rediscover just how naturally beautiful many fruits are. Try to eat the actual fruits instead of getting juice – the fibre helps slow the flow of sugar into your bloodstream.

6. Supplements. The most important are fish oil/omega 3 capsules which come with a side helping of Vitamin D – perfect for sharpening the old brain functions and making us feel less depressed about being mid-winter. There is no Vitamin D RDA and although we probably get enough help from the sun during summer, we need to supplement like crazy in winter. If you are over 50 you should be taking a Vitamin D supplement all year round. Vitamin D deficiency has been linked to all the old life threatening bad pennies of heart disease, diabetes and cancer and more research needs to be done to see exactly what deficient people are missing out on. As far as other vitamins are concerned: if you can manage a small daily dose of vitamin C, this will also help to reduce your chances of getting a bad cold.

See, not a massive change, but will help you start to feel loads better and you might be inspired to effect a bigger change in your lifestyle. It doesn’t take much to get your body back on track – our organs, especially our main detox organ – the marvellous liver – are very resilient and do their very best job with just a little help from us.
