Oh Really?

This is an area where common sense, your mother’s advice and science have finally met. Having a good cry to relieve your frustration, tension or unhappiness is what we naturally tend to do, usually accompanied – if we are lucky – by someone holding our hand and telling us to ‘let it all out’.

Scientists love to explain the everyday things we have all taken for granted, and reported by the Association for Psychological Science is a joint study by the University of South Florida and Tilburg University in the Netherlands that explores the benefits of crying. Not surprisingly they found that most people in their study reported improvements in their mood following a bout of crying, but that around a third found no difference and a tenth felt worse.

The blessing of a senior memory

If you tend to see the past as having hotter summers, more fun and fewer problems then that’s a benefit of ageing. At least it is according to Neuroscientists from Duke University Medical Center in the USA as they have reported in the online issue of ‘Psychological Science’. They have discovered activity in the brain that causes us to remember fewer of life’s negative events than younger people – presumably because they are nearer in time to the bad events.

It seems that as our brains get older then they allow negative memories to fade away. It’s because older people use their brains differently than younger people when it comes to storing memories, particularly those associated with negative emotions. The study focused on two groups; over 70′s and under 25′s who were shown a series of 30 photographs while their brains were imaged in a functional MRI (fMRI) machine. The pictures varied from neutral to having very strong negative images such as attacking snakes, mutilated bodies and acts of violence. While in the fMRI machine, the subjects looked at the photos and ranked them on a pleasantness scale.

Later, they were then asked to recall the pictures while being scanned again and the results found that the older adults had less connectivity between areas of the brain that generate emotions and those of memory and learning, but had stronger connections with the frontal cortex, the higher thinking area of the brain that controls these lower-order parts of the brain.

In contrast, the young adults used more of the brain regions typically involved in emotion and recalling memories. This meant that they were able to recall more of the negative photos and that because the older adults were using more thinking than feeling, that they didn’t recall the more emotive, negative, pictures nearly so well.

The conclusion was that although the emotional centres of the older people were just as active as those of younger subjects, their brain connections were different. For older subjects the benefit is that they had over their lifetime learned to be less affected by negative information in order to maintain their well being and emotional state. So the summers may not have been hotter, but how nice to remember them that way and shut out all those days spent huddling under an umbrella on the sands.

Oh Really?

Sorry, couldn’t resist this one – and although this piece of research confirms what we already know, it’s valuable to remember it at this stressful time of year. We know that stress is a powerful trigger for heart attacks and strokes, but apparently it is not the stress in and of itself that is the problem it is the unhealthy coping mechanisms that we often turn to that have been investigated by University College in London. When I talk about stress in my book ‘How To Cope Successfully With Stress’ I point out that stress is not always a bad thing; it is how you cope with it that is important. If you turn to healthy methods of dealing with it like meditation, exercise and changes in diet then you can handle it without adverse health effects.

However stress makes us reach for those comfort props whether that is food, alcohol, or smoking and those are the factors that impact on your health and can lead to heart disease or strokes. When we are stressed our good health resolutions often go by the board and we stop exercising and eating healthily and generally take less good care of ourselves. If you get stressed, try to maintain at least some healthy habits and make your ‘comfort’ blanket a little more active – swop it for a down filled coat and go for a walk.

Selenium has role in preventing high risk bladder cancer

Selenium is an essential trace element that we need for health, and now it seems it could play an important role in preventing high risk-bladder cancer for certain groups of people. Researchers from Dartmouth Medical School this month reported in a journal of the American Association for Cancer Research that although not true for everyone some groups who had been newly diagnosed with bladder cancer showed significant reductions in their cancer when they were found to have higher rates of selenium than average in their bodies. The groups affected were women, moderate smokers and those with p53 positive cancer. While other studies have shown a similar association between selenium and bladder cancer among women, this study is one of the first to show an association between selenium and p53 positive bladder cancer. Selenium is a trace element found widely in the environment and good food sources include Brazil nuts, bread, fish, meat and eggs Christmas excess – be prepared!.

Oh Really?

I don’t know, you do one of these items and along comes another – this one for the chaps. More in the category of ‘well we could have guessed that’ comes the news that men who were have an increased risk for prostate cancer are almost twice as likely to undergo screening for the disease if married or living with a partner. As most men are far more reluctant to consult doctors for anything, this is no surprise so if you want to have a healthy prostate don’t stay single seems to be the advice and comes from no less a body than the University of Michigan.

They found that although prostate cancer screening programmes specifically target men with a high risk for the disease, little is known about the factors that influence these men to take the decision to get tested. But, apparently, one of the factors that gets them to the screening is fear – no surprise there – and accompanied by a relationship where they are ‘persuaded’ (read nagged) into going for checkups is the most effective of all.

Fruit drinks and chemicals

Well it’s nice to be a world leader, but not when it comes to being up there because we have some of the highest levels of pesticides in fruit-based soft drinks. Spanish researchers checked drinks in many European countries and the USA and we came joint first with Spain, and the USA – usually home of the additives – came out well, as did Russia.

The study was reported in the December 15 issue of the journal Analytical Chemistry, and has revealed a basic flaw in the regulatory system for pesticides. Although levels of pesticides are strictly regulated in fresh fruit, vegetables, and drinking water there has been no follow through on fruit-based soft drinks.

The scientists measured the levels of a wide range of common pesticides in more than 100 fruit-based soft drink samples from 15 different countries. Pesticides they tested were those that are applied to crops after harvest and are known to still be able to be present during any processing methods. These included carbendazim, thiabendazole, imazalil, and malathion, and were found in fairly large concentrations in most of the samples analyzed.

The main concern is for children as their systems are more vulnerable to these chemicals, and they tend to have more fruit-based soft drinks than adults do. Until there is legislation in place it would be sensible to limit such drinks or make sure they come only from organic sources – make your own by buying organic apple juice concentrate and diluting it with water.

Oh Really?

Haven’t done one of these for a while, but sometimes one comes along that is irresistible. Are you ready for this earth shattering revelation? John P. Robinson and Steven Martin are the happy sociologists from the University of Maryland who were given real money by apparently sane people to find out what activities contribute most to a happy life.

Now lots of people have already written many books on this subject, but as always there is still more to learn. They ploughed through the diaries of over 30,000 adults over a 30 year period and analysed what they did and how pleasurable they found it.

What their research has shown them is that people who described themselves as happy were more socially active, attended more religious services and read more newspapers. Unhappy people, however, watched more television. As one of the prime symptoms of depression and unhappiness is withdrawal from the society of others this doesn’t strike me as a major breakthrough, but what do I know.

Apparently television watching provides temporary pleasure to unhappy people; but, in the long run is a waste of time and not particularly fulfilling. The others compare it to an addiction where you get momentary pleasure and long-term misery. They must have been watching Strictly Come Dancing, but they did come up with a neat catch phrase, that ‘tuning in’ can be an easy way of ‘tuning out’ so I can forgive them for making me feel like a social outcast because of my addiction to brilliant US drama series like Boston Legal and The Closer. ”

So, stun your family by letting them know that happy people read and socialize while unhappy people watch TV. If that doesn’t get them playing charades or monopoly after Christmas dinner, then nothing will.

Anyone interested in paying me to study whether breathing is a necessary evil?

Important new finding on bone health

For the first time ever, a link has been made between the body’s production of serotonin in the gut and the production of osteoblasts, the cells that create new bone. Normally we associate serotonin with the brain and its role in our ‘feel good’ moods, but apparently a new study has found that 95% of the body’s supply of this molecule is produced in the gut and it is acting as a hormone to regulate bone mass,”

In an online paper published in the Journal Cell, a team led by Dr. Gerard Karsenty, chairman of the department of genetics and development at Columbia University in the USA have uncovered what could be a new way to control bone formation and treat could osteoporosis. Dr. Karsenty has found that gut serotonin is released into the blood, and the more serotonin that reaches bone, the more bone is lost. The reverse also applies; the less serotinin in the bloodstream then the denser and stronger bones become. As part of his study Dr. Karsenty was able to prevent menopause-induced osteoporosis in mice by slowing serotonin production. Osteoporosis is often dubbed ‘the silent killer’ because it is rarely diagnosed until the condition is established and bones start to break and fracture under little pressure. Conventional osteoporosis treatment has focused on preventing bone loss, such as with bisphosphonate drugs like Didronel, Fosamax and HRT, but unless action is taken to build bone then the situation eventually deteriorates. There are two more natural alternatives to such osteoporosis drugs, one of which is made known to us through this new study. Its findings have huge implications for osteoporosis treatment, as it could be a simple matter of regulating your diet. The basic building block for serotonin in the body is the amino acid tryptophan, which is found in red meat and turkey and in chocolate, oats, bananas, milk, yogurt, eggs, fish, poultry, sunflower and pumpkin seeds, and peanuts. So if you have a tendency to osteoporosis in your family, which is one of the biggest risk factors, then aim for a diet low in tryptophan foods to help minimise your bone loss.

The other approach, that has been tried and tested by many osteoporosis sufferers, is to use the hormone that is essential for bone-building and that is progesterone. Its levels decline with age and it is a simple matter to supplement with natural progesterone cream, patches or tablets. Though notionally available on the NHS in the UK, it is more likely to be offered as a private prescription and it cannot be bought over the counter in the UK, though it is perfectly legal to import it for your own use. If you want to know more about this hormone, the book Natural Progesterone by Dr Shirley Bond and myself will answer all your questions (you will find it on my website) and you can find plenty of suppliers of the cream that Dr John Lee recommended including Wellspring who operate out of Guernsey and have a helpful website at www.progesterone.co.uk

Natural help for eyes

As we get older our eyes become vulnerable, and around 1 in 7 over 55 year olds will suffer from macular degeneration. This is the leading cause of blindness and severe vision impairment worldwide, and a study in the Archives of Ophthalmology reports on the benefits of Omega-3 for reducing the risk.

Macular degeneration (MD) affects central vision and this gradually deteriorates causing functional blindness. Peripheral vision is not at first greatly affected; but over time peripheral vision is also reduced. A study of 8,000 people in the Netherlands found that those who developed the disease were more likely to be smokers and have high cholesterol and that because free radical damage has been linked to MD that antioxidants can reduce the disease’s progress.

However, a more recent study has shown a clear link between consumption of Omega-3 and reduction in age-related MD. Dr Chong of the University of Melbourne did a meta-analysis of nine studies which covered 90,000 people, and 3000 of those had age-related MD.

Back to the benefits of fish again, because her study found that eating just one portion of Omega-3 rich fish may reduce the risk of contracting MD by over 50%. In fact increasing your daily intake by 300 mg per day of the Omega-3 fatty acids DHA and EPA, reduces the risk of MD by about 70%.

If fish really isn’t your favourite then you can get Omega-3 from flaxseed oil which is also rich in lutein and that’s one of the antioxidants that boosts eye health and prevents cataracts and macular degeneration. These are the essential elements for good eye health:

BETA-CAROTENE which destroys free radicals and helps keep eye tissue healthy.

VITAMIN C and VITAMIN E are antioxidant and protect the eye from sun damage

ZINC and COPPER are antioxidant and protect our eyes

B VITAMIN complex to fight free radicals in your eyes, particularly the cornea and the myelin sheath around the optic nerve

TAURINE is an essential amino acid for retina health and blocks out UV rays and environmental toxins.

EYEBRIGHT is a herb that been traditionally used to relieve irritated eyes and strengthen blood vessels in the eyes.

Otherwise it’s the usual mix of dark green leafy vegetables, particularly spinach, and a varied daily diet to keep your eyes sparkling.

Cheer up your heart

I was extolling the virtues of laughter in this article about laughter yoga, and now here’s another of my favourite stress busters which can have a wonderful effect on your heart health. No drugs and no side effects are involved you just need to listen to some joyful music and the function of your blood vessels will be vastly improved, and that’s good for your heart.

No I didn’t make it up just because I love listening to music, it’s based on research presented by the University of Maryland School of Medicine at the recent American Heart Association Scientific Sessions meeting in New Orleans. So, tune in your radio, or get out your favourite piece of music – the only criteria is that it must give you a great sense of joy – so whether it’s Bach, the Beatles, or Bonzo Dog they will all have the same health-giving benefits.

What happens when you listen to music is that the tissue in the inner lining of your blood vessels dilates and that increases blood flow. Known as the endothelium, the lining of blood vessels has a powerful effect on health, especially the development of cardiovascular disease, because it regulates blood flow and adjusts blood thickening and coagulation. Plus, at no extra cost, it releases substances in response to wounds, infections or irritation. So be kind to it and play it something wonderful! Don’t however put on the funeral march or anything that stresses you like heavy metal, as if then your blood vessels will narrow and restrict blood flow.

For the statistically minded, the research showed that blood vessels dilated an extra 26% for joyful music and music that stressed the listener narrowed blood vessels by 6%. I think it might be time to give up listening to Leonard Cohen – or at least ration my intake on health grounds. Oh, and I also know that signing has the same good effect, and as I have been lucky enough to be in a couple of passenger choirs on cruise ships recently I can highly recommend it as both joyful, and stimulating as you try to remember the words and work out if it’s you or your neighbour that is singing off-key!
