The Positive Side of Coffee

If you have forsworn the beverage as part of your New Year healthy eating plan you may want to rethink as new research is showing some benefits you won’t want to pass up on. Personally coffee, like butter, is something I have never given up on but have cut down to two cups a day because my health philosophy has always been everything you want in moderation.

Coffee is actually one of the richest sources of antioxidants there is and remains so however you drink it as its high antioxidant content of the coffee is still absorbed easily by the body. Antioxidants help to protect our cells from free radical damage caused by oxidative stress – a fact that is backed up by hundreds of intervention studies on polyphenols and polyphenol-rich foods including coffee.
According to Gary Williamson, Professor of Functional Food, School of Food Science and Nutrition at the University of Leeds, “Coffee is in my top 20 lifespan essential foods.” Many people can’t start their day without it and if you want a quick and high oxidant boost then look for Nescafe have even developed a special blend that is higher in antioxidants than their standard coffees so look for their Green Blend in supermarkets.

Other Caffeine Benefits:
A new review has indicated that antioxidant supplements may benefit couples who have difficulty conceiving naturally. The review provides evidence from a small number of trials that suggest the partners of men who take antioxidants are more likely to become pregnant so coffee could well play a part in that antioxidant increase.

Another new study also shows that caffeine energizes cells, boosting virus production for gene therapy applications. Now why would that concern you? Well it helps move research forward faster because if you give caffeine to cells engineered to produce viruses used for gene therapy then those cells can generate 3- to 8-times more virus, according to a recent paper published in Human Gene Therapy.

Lentivirus vectors are commonly used for transferring genes into cells for both research applications in the laboratory and, increasingly, for gene therapy procedures in clinical testing. The addition of caffeine should significantly decrease the cost of lentiviral production for research and clinical uses and James M. Wilson, MD, PhD, Editor-in-Chief, and Director of the Gene Therapy Program, Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, Philadelphia can certainly see the advantage. “It is ironic that the ingredient in beverages like colas and coffees that helps keep us awake and alert is also useful in jazzing up cells to produce more gene therapy vectors. An increase in vector production of 5-fold may prove critical in establishing the commercial viability of lentiviral based products.”

Why Cutting Tablets In Half Is A Dangerous Practice

You may have trouble swallowing large tablets, or not want to take all the dose of your medicine at one time, but now medical experts have issued a warning after a study found that nearly a third of the split fragments deviated from recommended dosages by 15 per cent or more.

You may think it not important, but there can be serious clinical consequences for tablets that have a narrow margin between therapeutic and toxic doses. There is a particular concern about the practice in nursing homes where many residents are on complex regimes for a range of health conditions, including Parkinson’s, congestive heart failure, thrombosis and arthritis.

Researchers from the Faculty of Pharmaceutical Sciences at Ghent University in Belgium, asked five volunteers to split eight different-sized tablets using three techniques commonly used in nursing homes. It was not good news: 31 per cent of the tablet fragments deviated from their theoretical weight by more than 15 per cent and 14 per cent by more than a staggering 25 per cent. Even the most accurate method produced error margins of 21 per cent and eight per cent respectively.

The end result is tablets are often unequal sizes and a substantial amount of the drug can be lost during splitting. The study involved four volunteers – only one of whom was a nurse in order to replicate common nursing home conditions. Between them they split tablets into 3,600 separate quarters or halves using a splitting device, scissors and a kitchen knife. The eight different tablets were different shapes and sizes, three were unscored, three had one score line and the others had two.

If splitting tablets is something you regularly do, then the best advice is to invest in a splitting device as it gave the most accurate cut. However it still produced a 15 to 25 per cent error margin, but still lower than using a knife or scissors.

The researchers recommended that manufacturers offer more options such as liquid formulations and a wider range of tablet doses. Also that staff in nursing homes should receive training to enable them to split tablets as accurately as possible.

Warfarin and Supplement Interactions – and What About Food?

Way back in 1988 I was Editor of a book called The Medicine Chest which was a straightforward examination of the interactions between drugs, supplements and foods. It had a lot of good advice that hasn’t changed much over the years so I was surprised to receive a ‘news’ item that warned that Warfarin when taken with vitamin E and large doses of vitamin C can decrease effect of the drug.

I was not surprised at the effect because I was writing about it over 20 years ago, but that it was news came as a surprise. However, it never hurts to repeat a good piece of information and scientists never turn up a chance for a grant to research something we already know.

This time it is researchers at the Intermountain Medical Center Heart Institute in Salt Lake City, Utah who want to point out the dangers. Warfarin is a commonly prescribed drug used to prevent blood clots from forming and given to people with certain types of irregular heartbeat, those with prosthetic heart valves, and those who have suffered a heart attack.

The study consisted of interviews with 100 atrial fibrillation patients to determine their understanding of potential interactions between supplements and medications such as Warfarin. This is not really a study about interactions but of people’s understanding of them and generally people do not know enough about how supplements, and everyday foodstuffs react with their medication.

In this study more than half were unaware of potential interactions and they also found that of the 100 most-used supplements (vitamins, glucosamine/chondroitin, fish oil and coenzyme Q10) 69 percent interfere with the Warfarin’s effectiveness.

Warfarin and herbal and dietary supplements “compete” in the liver and this competition changes the way the blood thinner works — either intensifying its active ingredients, thereby increasing the risk of bleeding, or by reducing its effectiveness, increasing the risk of stroke.

All true, and the lead researcher is urging that doctors do a better job of teaching patients about the dangers of mixing Warfarin with these products. Now I entirely agree with him, but what he doesn’t mention is that this particular drug is also seriously affected by certain foodstuffs and other drugs.

Given what the average doctor knows about nutrition I hold out little hope they will also pass on this advice so that instead of increasing or decreasing their drug prescription they could suggest changes to their patients diet. In addition, the effectiveness of Warfarin is impacted by other drugs – particularly antifungals, barbiturates and beta blockers which all decrease the drugs effectiveness.
Conversely, antibiotics, some diabetes drugs, gout medicines, tricyclic antidepressants and asprin and paracetamol – among others – all can increase the drug’s effectiveness, making it more potent.

On Warfarin? Avoid These:
Warfarin is affected by large doses of vitamin E, vitamin C, bioflavanoids and calcium and a large intake of fats or oils. If the diet is also high in vitamin K rich foods this can cause an imbalance in the body which could decrease the anticoagulant effect.

Vitamin K is needed to allow your blood to clot normally, to protect your bones from fracture and postmenopausal bone loss, to prevent calcification of the arteries and provide possible protection against liver and prostate cancer.

Vitamin K is a fat soluble vitamin and only a small amount is able to be stored in the body. It is destroyed by light and acids and alkalis such as vinegar or baking soda. A deficiency of it can lead to increased blood clotting time, easy bruising and excessive bleeding.

Significant food sources include: green leafy vegetables including spinach, Brussels sprouts, Swiss chard, green beans, asparagus, broccoli, kale and also cauliflower, cow’s milk, eggs, fish liver oils, green vegetables, kelp, liver, molasses, polyunsaturated oils, tomatoes

Everyone responds differently to drugs, foods and supplements so if you have any concerns, or if your diet is high in vitamin K rich foods, then you should discuss with your doctor how this is affecting your medication.

Statins Update – News and Views

November 17, 2010 by  
Filed under Health, Medical Research & Studies

Statins are regarded as a lifesaver by some and a dangerous medication by others. I have written on this before and just by coincidence this week three separate news stories turned up on different aspects of these drugs.

Their primary use is to lower blood cholesterol levels by blocking the action of a chemical in the liver that is necessary for making cholesterol. So far so good, and they are used to maintain normal cholesterol levels and so lower the risk of chest pain (angina), heart attack, and stroke.
Unfortunately, in my view, they are over prescribed and used to simply alleviate anxiety about possible future health conditions and instead of promoting healthier lifestyle choices through diet and exercise. Here is the news – and you make up your own mind.

Statins 1: The Good News
Study results presented at the Ninth Annual AACR Frontiers in Cancer Prevention Research Conference, held Nov. 7-10 in Philadelphia have indicated that long-term statin use is unlikely to increase cancer risk for bladder, breast, colorectal, lung, pancreatic, prostate, or renal cell cancer, but was associated with lower risk of melanoma, endometrial cancer and non-Hodgkin lymphoma.

This was a decent-sized study that included 133,255 participants in the Cancer Prevention Study II Nutrition Cohort and they completed several questionnaires and were followed over a period of about 10 years. During that time more than 15,000 participants were diagnosed with cancer.

Statins 2: The Not So Good News
According to a study in the British Medical Journal statins significantly increase a person’s risk of cataracts, muscle weakness, liver dysfunction and kidney failure. Unlike the previous report, they also confirmed that the drugs lower the risk of heart disease and oesophageal cancer, but claims of other health benefits were unsupported.

Again this study is a respectable size, as researchers from Nottingham University examined data on more than 2 million patients between the ages of 30 and 84, seen at 38 different general practices, who had been prescribed statins.

The researchers confirmed prior data suggesting that statins increase patients’ risk of cataracts, liver dysfunction, kidney failure and a form of muscle weakness known as myopathy. They found that for every 10,000 women treated with the drugs, 23 would develop acute kidney (renal) failure, 39 would develop myopathy, 74 would develop liver dysfunction and 309 would develop cataracts. Men suffered an even higher risk of myopathy, but their risks of the other three conditions were similar to those suffered by women.

In a nutshell, the researchers found that only 434 people would need to be treated with the drugs for five years for one case of acute renal failure to develop. It would take only 136 treated for each case of liver dysfunction and 33 for each case of cataracts. Among women, 259 would need to be treated for each case of myopathy; among men, the number was only 91.

The risk of developing all conditions was highest during the first year of treatment, but continued throughout the course of the study. Risk of liver and kidney problems increased proportionally with the dose of statins being taken.

Further research involving statins and cancer has come from the large population-based Women’s Health Initiative (WHI) in the US. Their findings are that statins fail to reduce colorectal cancer in postmenopausal women.

Michael S. Simon, M.D., professor of oncology in the department of oncology at Wayne State University and Barbara Ann Karmanos Cancer Institute, Detroit presented these study results at the previously mentioned Ninth Annual AACR Frontiers in Cancer Prevention Research Conference and according to him, the results from several case-control studies have shown a moderate reduction in colorectal cancer risk in people who use statins. However, a majority of the literature researching the association, including data from randomized controlled trials and cohort studies, show no association between statin use and reduced colorectal cancer risk.

Statins 3: Better News
The Nottingham researchers did find, however, that the risk of cataracts returned to normal within one year of stopping statin treatment, while the risk of liver and kidney problems returned to normal within one to three years. Additionally, they found no connection between statin use and the risk of dementia, osteoporotic fracture, Parkinson’s disease, rheumatoid arthritis or venous thromboembolism.

Unlike stated in Statins 1, these researchers found almost no data supporting claims they reduced cancer risk. The study “largely confirmed other studies that reported no clear association between statins and risk of cancers,” according to the researchers. The only cancer-fighting effect uncovered in the study was a slightly lower risk of oesophageal cancer, with eight cases averted for every 10,000 high-risk women treated. In other words, 1,266 high-risk women or 1,082 high-risk men would need to be treated with the drugs to prevent one case of oesophageal cancer.

It is a lot to take in, and you are going to have to assess your own risk of potential heart disease and high cholesterol against the other health risks associated with these drugs. As ever, adopting a healthier lifestyle is an essential first step to dealing with high cholesterol before resorting to any drug regime.

Being Bi-Lingual Could Avert Alzheimer’s by 5 Years

November 16, 2010 by  
Filed under Health, Healthy Ageing, Medical Research & Studies

There are many suggested ways to delay or even avert Alzheimer’s and they usually revolve around staying mentally active. Now new research from Canada has found more dramatic evidence that speaking two languages can help delay the onset of Alzheimer’s symptoms by as much as five years.

The latest study examined the clinical records of more than 200 patients diagnosed with probable Alzheimer’s disease and found that those who have spoken two or more languages consistently over many years experienced a delay in the onset of their symptoms by as much as five years. Dual language capability is not uncommon in Canada where many speak both English and French and the science team are not claiming that bilingualism in any way prevents Alzheimer’s or other dementias. What they are saying is that it may contribute to cognitive reserve in the brain which appears to delay the onset of Alzheimer’s symptoms for quite some time.

The lead investigator is Dr. Craik who is also co-editor of The Oxford Handbook of Memory and he clarified that the brains of people who speak two languages still show deterioration from Alzheimer’s, however their special ability with two languages seems to equip them with compensatory skills to hold back the tell-tale symptoms of Alzheimer’s, such as memory loss, confusion, and difficulties with problem-solving and planning.

The researchers found that bilingual patients had been diagnosed with Alzheimer’s 4.3 years later and had reported the onset of symptoms five years later than the patients who spoke only one language. Interestingly, there was no apparent effect of immigration status, and there were no gender differences.

The current study adds to mounting scientific evidence that lifestyle factors – such as regular cardiovascular exercise, a healthy diet, and keeping mentally alert – can play a central role in how the brain copes with age-related cognitive decline and diseases such as Alzheimer’s.

“Although a great deal of research is being focused on the development of new and more effective medications for Alzheimer’s disease, there are currently no drug treatments that show any effects on delaying Alzheimer’s symptoms, let alone delaying the onset of these symptoms by up to five years,” said Dr. Freedman, head of Neurology and director of the Sam and Ida Ross Memory Clinic at Baycrest.

That being the case it might be time to dust off the Linguaphone records, or sign up for a language class at your local adult education centre. Chinese ought to be difficult enough to stir the brain cells into action!

Curing the winter blues

November 9, 2010 by  
Filed under Health, Natural Medicine

In the winter many people are affected by the lack of light and their mood can plummet. Added to this is the anxiety felt by many people as the Christmas season approaches with all the organisation and stress that sadly often accompanies it.

To keep on an even emotional, mental and physical keel our bodies need dopamine, an important neurotransmitter recognised as being vital for cognition, movement, motivation, sleep, mood, libido, attention and learning. Dopamine is the key neurotransmitter that allows the brain to flourish and develop, and maintaining adequate levels is central to relieving anxious, stressful states.
Being advised to stay calm may not always be enough and if you want to increase your natural dopamine levels to help lift your mood, then help is at hand. It’s probably not the first thing you think of but blue-green algae may be the answer.

Klamath is the name of a Native American tribe but in this instance also refers to the blue green algae which is Aphanizomenon flos-aquae. It is one of only two natural sources of phenylethylamine (PEA) which our nervous system naturally produces when we are calm, happy and focused. It also has the ability to raise the level of freely circulating dopamine within the brain and nervous system which helps keep us alert, active and motivated.

A new product, vitalCALM from Simply Vital, contains highest quality source of Klamath blue-green algae and is a concentrated source of PEA. It is an advanced nutritional supplement for the nervous system and provides support for conditions associated with altered dopamine functioning such as: ADHD, anxiety, depression, fatigue, fibromyalgia, insomnia, obesity and Restless Legs Syndrome.

VitalCALM has been developed to provide an all-natural boost to dopamine levels and might just be the answer to those winter blues and to ward off those feelings of the approaching Christmas crisis! If you would like more information go to www.simplyvital.com.

The Clock Is Ticking – Act Now To Keep Herbal Medicine On The Shelf

November 1, 2010 by  
Filed under Health, Natural Medicine

Earlier this year I raised the issue that many of our popular alternative remedies are under increasing threat from EU legislation and we are now up against the clock if we want to try and stop it from happening. Herbal medicine has an old and respected tradition, indeed without it many of our modern drugs would not exist.

Modern science has sought out and taken the active ingredients from medicinal plants and synthesised them, with the heart drug digitalis from the foxglove being a common example, as is aspirin from white willow bark. Now your right to use the original, natural plant based remedies could be at an end.

With strict European legislation due to come into force next April, some age-old herbal remedies on sale in health food stores today could become, quite literally, a thing of the past. From April 2011, all member states will have to comply with a European Union directive which specifies that all herbs produced, manufactured and sold in the EU must be classified as either foods or medicines.

Those working in the sector have for a long time been campaigning for regulation and greater control, but the new authorization and licensing requirements have enormous implications for the herbal medicine industry throughout the European Union and for your freedom of choice.

Marinella Trovato, President of S.I.S.T.E., the Italian Society for Herbal Science and Technology in Milan, said that many small producers and manufacturers of medicinal herbs will no longer be able to afford to stay in business as they will be unable to cover the cost of authorization licences for medicinal herbs. UK-trained herbalist, Marco Valussi, speaking at the conference, warned that the terms of the directive would put herbal remedy manufacture in the hands of large pharmaceutical companies, and this was likely to narrow the range of medicinal herbs on the market.

Now that major companies like Boots have their own range of herbal medicines is this not a good thing? Yes, but what you see with large companies is that they are interested in a small rage of remedies that are the most popular, and profitable. However the range of herbal medicines available at the moment is huge and covers all aspects of health care.

What putting herbal medicine into the hands of the large companies means is that they are more likely to focus on maybe five or ten important herbs and leave behind the other ones that are just as valuable, but as popular.

If you value your freedom of choice it is almost too late to register a protest – but not quite. I don’t want to spend a winter without Echinacea to boost my immune system, so if you have benefited from herbal medicine then please take a moment and register your protest with your MP.

A very simple way to do this is to go online where you will be taken through a simple form that will be sent online directly to the MP for your area so copy and paste this link into your browser and make a healthy difference:

Food is the major source of human antibiotic exposure

October 6, 2010 by  
Filed under Health, Medical Research & Studies

I have often spoken — indeed quite recently — about the dangers of the overuse of antibiotics and you may have patted yourself on the back and thought ‘well I hardly ever have them’ — but I bet you do.
The problem is that you are probably not even aware of it — particularly if you are a meat eater. A new study has shown that what you ingest from your diet is an important factor in the levels of toxicity in your body.

In a conventional, Western, diet you are taking in the antibiotics and hormone growth promoters that are routinely fed to cattle and intensively farmed salmon and chicken and through the pesticides used in modern intensive farming. This can leave you with quite a high level of toxic chemicals in your body — if you are a wholly organic vegan, you can skip the next bit but everyone else might find it of interest.

In order to test the theory that vegetarians are healthier, scientists recruited 25 people to stay at a Buddhist temple for five days, living the same lifestyle as the monks residing there. This lifestyle included adhering to a strictly meat-free diet and I imagine was also fairly stress-free, unless they were suffering severe withdrawal symptoms from their iPhones and computers..

The researchers took urine samples from all participants both 48 hours before and immediately after their five-day retreat and it was tested for antibiotics and their metabolites, as well as six chemicals produced by the body upon the breakdown of phthalates.

What are phthalates I can hear you cry? They are industrial chemicals used in the manufacture of pesticides and soft plastics and have been proven to interfere with our bodies hormonal systems, producing defects of the reproductive, nervous and other bodily systems. Because it is difficult to detect phthalates in urine, the researchers instead had to test for its metabolites.

All six phthalate metabolites were detected in every participant both before and after the study, but levels of levels of all drugs had dropped dramatically. and five metabolites had significantly dropped over the course of the study. That is in just five days — which is quite impressive.

These findings suggest that food is one of several sources through which humans are exposed to phthalates. The researchers found that participants who had eaten more beef, pork and dairy prior to the study started out with higher phthalate levels than participants who had eaten less of those foods.

The good news is that it is relatively easy to reduce the level of drugs and toxins in the body by switching to a diet that contains less meat and more vegetarian sources. I am not suggesting you give up meat altogether, but one idea for a healthier diet is certainly to have at least one or two meals a week that are meat-free.

Cognitive decline can start in the womb in malnourished pregnancies

September 22, 2010 by  
Filed under Health, Healthy Ageing, Medical Research & Studies

One of the conditions that most frightens us, and has seen such a rapid increase in the last 50 years, is Alzheimer’s with its accompanying cognitive decline. Now there is an interesting new approach based on a recent retrospective study that seems to indicate that poor or inadequate nutrition during the early part of pregnancy appears to accelerate cognitive decline in later life for the baby.

This work has been based on a study of people exposed to severe prenatal malnutrition in the Netherlands during World War II, but I believe also has great significance for the increasing number of people in the West who are on nutritionally poor diets. This was a regression analysis of almost 300 men and women born in Amsterdam during a severe food shortage in the winter of 1944 to 1945 and what the researchers found was that those conceived during that period (and considered to be exposed to famine in utero) performed significantly worse when tested for selective attention at ages 56 to 59.

During the winter of 1944 and 1945, a severe food shortage struck the western Netherlands as a result of a German embargo on food transport in response to a Dutch railway strike intended to hamper German troop movements. Food rations among this normally well-nourished population rapidly fell to as little as 400 to 800 calories per person during the five to six months of famine.

Susanne R. de Rooij, PhD, of the University of Amsterdam, led the study and she hypothesized that because the Dutch group had previously associated prenatal exposure to famine with coronary heart disease and diabetes — both aging-related chronic diseases — that this early exposure may also lead to premature age-related cognitive decline.

Indeed, they found on regression analysis that exposed individuals performed significantly worse in cognitive function tests than those who had not suffered this nutritional devastation. The study subjects were 56 to 59 years of age and undertook a general intelligence test, a perceptual motor-learning task, a memory task, and a selective attention task.

The participants did no worse than the control group on any of the tests except for that of selective attention. The researchers have speculated that those exposed to malnutrition during the first part of pregnancy are most vulnerable and a possible explanation is because of the effect of malnutrition on the development of the central nervous system, which occurs early in gestation. Another possibility is that the cognitive decline reflects vascular damage, which is supported by the researchers’ previous finding that famine exposure was associated with dyslipidemia and coronary heart disease.

Why these findings affect all of us:

This is not a definitive study, but I do think it’s worth paying attention to. The effect of nutrition on development throughout life is well known and I, along with many others interested in natural health, definitely see a link between the increase in conditions such as Alzheimer’s and the worsening dietary habits in the West.

We know from previous research that the vitamin and mineral content of food has been seriously depleted by modern farming methods and the overuse of pesticides and antibiotics in the animal food chain. Much of what we eat is nutritionally barren, and an addiction to fast foods, sugar and empty calories is leading to the current generation, who are the parents of the future, passing on their own nutritional deficiencies to their children.

Those who are trying to start a family know that the best advice they are given is to make themselves as healthy as possible in order to have a truly healthy baby. I have previously touched on the decline in both numbers and potency of the current generation’s sperm due to the environmental effect of such things as xenoestrogens and we also know that whatever the mother takes into her body during pregnancy will pass through the placenta to the baby. A generation reared on Diet Coke and McDonald’s are not essentially giving their unborn child the best start in life.

Bisphenol A Link to Dental Treatment Problems

September 20, 2010 by  
Filed under Childrens Health, Health, Medical Research & Studies

The danger of BPA is something I have highlighted previously in other newsletters, particularly in relation to children, and now there appears to be yet another cause for concern relating to dental treatment. BPA was originally produced for use as a synthetic hormone in 1936 and today is most commonly used as the building block of polycarbonate plastic for products such as baby bottles and water bottles, epoxy resins (coatings that line food containers), and white dental sealants. It is also an additive in other types of plastic used to make children’s toys.

To date there is extensive scientific literature reporting adverse effects of BPA at doses lower than the current level considered safe by U.S. EPA, a high rate of leaching of BPA from food and beverage containers, and evidence that the median BPA level in humans is higher than the level that causes adverse effects in lab studies.

Children are Most at Risk:

Growing children are particularly at risk to chemicals in their environment because they face greater exposure per pound of body weight and are physiologically more susceptible to them. Children’s exposures begin at conception, as chemicals, including BPA, cross the placenta in a pregnant woman’s body and can affect the embryo or foetus during critical periods of development.

Now there is even greater cause for concern as, according to researchers from Mount Sinai School of Medicine, bisphenol A (BPA) is also released from some plastic resins used in dentistry. They found that this is detectable in the saliva after used during routine dental treatment and among the many risks associated with BPA are changes in behaviour, urinary tract development, and early onset of puberty. Adults of course are not immune either as prostate problems are also associated with BPA.

This study was carried out in the USA where children often have their teeth sealed with a dental resin containing BPA to prevent cavities, and it is often used for fillings. Although they point out that exposure to dental treatment is much less common than children being exposed to BPA in everyday food containers for example it is still a cause for concern. Indeed, they go further and as a further precaution urge that resins containing BPA should not be used on pregnant women.
