Cancer survival – Surprising findings

It has just been reported in the May issue of the Journal of Clinical Oncology that a study done in Halifax, Nova Scotia, has shown – perhaps surprisingly – that many cancer survivors don’t follow healthy lifestyles.

Apparently they are more likely to be non-smokers (82.6% to 91.6%) than adults in the general population (79.5%) which with the worldwide smoking ban is not so surprising, but the fact that they are not more prone to exercise to recommended levels, or to have a healthy diets with the recommended ‘five a day’ of fruit and vegetables, certainly is.

In a study of more than 9,000 patients with a history of various cancers, it was seen that a staggering 80.9% to 85.2% were not following the healthy eating guidelines. This is despite evidence that shows that those patients with a history of cancer had a significantly improved quality of life if they followed the three golden rules of survival: exercise, no smoking and plenty of fruit and vegetables. In fact, only about one in 20 of all the patients were following all three recommendations, so if you have a cancer survivor in your family make it a point to see they understand how important a healthy diet is to live a longer, and better lifespan.

The key factors in keeping your kidneys healthy

As we get older, it is vital to keep your kidneys functioning at their optimum best and there are two very simple ways to do that which I will explain shortly.

First do you recognise the amazing job your kidneys do for you? Each one is not much bigger than a pack of playing cards and weighs only 4-5 ounces and yet they handle nearly 25 percent of the total amount of blood that your heart pumps while you’re resting and they consume the same amount of your body’s supply of oxygen. They need all that blood and oxygen because they have five critical functions to perform for you:

1. Keeping your blood clean by filtering it of waste products and eliminating these waste products from your body as urine.

2. Helping maintain your body’s fluid composition.

3. Stimulating the production of red blood cells in your bone marrow by secreting a hormone called erythropoietin.

4. Helping maintain your blood pressure by producing an enzyme called rennin

5. Convert vitamin D to its most active form for use by the body.

One of the most vital functions your kidneys carry out for you is in the process of creating urine through an incredibly complex filtering system and tip number one is to make it easier for it to do that by drinking plain water when you are thirsty. Small amounts drunk regularly is better than a large amount in a short period of time.

Those two tips for keeping our kidneys health as we age?

The first is to not eat too much protein as it leads to greater workload on your kidneys, which must filter a by-product of protein metabolism called blood urea nitrogen (BUN) out of your blood. How much is too much? Well, if you have healthy kidneys, you can safely eat up to half of your body weight (in pounds) in grams per day. For example, if you weigh 150 pounds and are in good health, you can safely eat up to 75 grams of protein from minimally processed foods per day. If you have problems with your kidneys, you should certainly decrease this amount to reduce the strain on your system. If you are not sure, then ask your doctor to monitor you as there are tests you can take to determine how well your kidneys are processing protein.

The second is not to take Non-Steroidal Anti-Inflammatory Drugs like ibuprofen and aspirin on a regular or frequent basis as they are known to cause kidney damage and disease. Such over-the-counter pain medications probably don’t pose significant danger if your kidneys are relatively healthy and you use them for emergencies only, so we are back to my cold again – thank goodness I don’t get more than 2 or 3 a year!

In the USA, one in nine adults has kidney disease and the best advice as ever is to be preventive and proactive. The same old boring, essential, stuff about a healthy non-processed diet, plenty of rest, exercise and freedom from stress. Take your body on holiday every day and get out into the fresh air – your body, including your kidneys, will thank you for it.

Mercury fillings – Safe or not?

Mercury is the third most toxic poison in the world, and you may not be aware of it, but it has been used in amalgam dental fillings since the 1830′s and most amalgams composed of at least 50% mercury. The debate over its use has been ongoing for some time; I certainly had all my amalgam fillings removed and replaced some ten years ago when I first started reading, and writing, about the potential health risks. The situation now seems to be polarising, and so I offer you both sides of the argument so you can make up your own mind.

In the red corner are the Scandinavians: on January 1st this year, Norway became the first nation to impose a total ban on the use of amalgam fillings in dental work. Previous laws forbid the use of mercury-containing fillings in more vulnerable segments of the population, such as pregnant women and children, but the new law is the first to forbid the use of the toxic metal without exemption. Mercury has also been banned from all other products produced, imported, exported, sold, and used in the country. Minister of Environment and Development, Erik Solheim, stated that “Mercury is among the most dangerous environmental toxins. Satisfactory alternatives to mercury in products are available, and it is therefore fitting to introduce a ban.” Sweden has now followed suit with a ban on mercury fillings that came into place on April 1st (2008), this year and Denmark and other EU countries are now contemplating similar moves.

In the Blue corner are Britain and the USA who do not accept that there is any problem with the mercury and say that all the negative claims are either unsubstantiated by rigorous scientific data or simply not significant enough to be of concern. They are backed up by a European Union scientific committee study which has claimed that amalgam fillings containing mercury pose no health risk to the human nervous system. The Committee said it had investigated claims of a link between amalgams and a variety of systemic conditions, particularly neurological and psychological or psychiatric effects.

They concluded that no risks of adverse systemic effects exist and the current use of dental amalgam does not pose a risk of systemic disease.

The findings reflect the opinions of some dentists and governments, who have insisted the material is safer and more durable than alternatives, but patients’ organisations have disputed the results, claiming amalgam is dangerous and that anyone carrying an average of 2.5 grams in their mouths is at risk. Another patient organisation in Spain said it rejected the provisional report because it was partial and ignored the World Health Organisation (WHO) and other scientists’ recommendations.

What do I think? Well, many European countries, including Britain, advise against the use of amalgam for children and pregnant women, due to its impact on brain development. In fact, research published in March 2006 shows neurodevelopmental disorders in children have decreased following the removal of thimerosal, a preservative containing mercury, from American childhood vaccines. This led to the World Health Organization urging that Thimerosal be banned in U.S. vaccines.

Amalgam fillings raise the level of mercury circulating in the blood as the mercury leaches from the filling into the body and it is believed to harm children’s normal development. Relatively low doses of mercury have been linked to adverse neuro-development and many people who have displayed sensitivity to the substance have reported improvements in health upon removal of the toxic fillings. It is often recommended that is removed in those with compromised immune systems and sufferering from immune responsive disorders such as ME.

As other types of composite fillings have become strong enough to replace amalgams under practically any circumstance, it would seem time to look realistically at phasing mercury out as a potential health hazard. If the health angle doesn’t convince you, perhaps the environmental one might do so. According to the US Environmental Protection Agency, medical waste incinerators emit 70,000 pounds of mercury into the biosphere each year, making medical use of the metal one of the leading contributors to mercury pollution. If you are thinking of having a tooth filling replaced, talk to your dentist and if you are having mercury fillings replaced that needs to be done with great care to avoid dust from the filling being absorbed back into your body. Ask your dentist if they are experienced in this type of removal and if they are not, it would be sensible to seek out someone who does this as a regular part of their practice work.

Let them eat grass – Wheatgrass

Wheatgrass seems to be the hot health idea at the moment and you can’t go into a trendy juice bar – as I am sure you do every other day – without being offered an expensive shot of green liquid. Like all ‘hot’ ideas it has actually been around for some time. In fact it has been something of a cottage industry, rather the old sprouters on the windowsill that were seen in all healthy homes in the 1970′s, you now find trays of wheatgrass or, if they are flat dwellers like me, it’s probably ‘grow your own grass’ for the cats.

However, wheatgrass has many great qualities as a supplement to your diet but unlike the sprouts, you don’t eat it – you juice it to get the maximum benefit. So what are these benefits? Well, increasing numbers of people are turning to it in their fight against cancer, to boost their immune system, and as an essential part of any detox programme. Wheatgrass first earned its reputation from people with terminal illnesses, who took it at the eleventh hour after conventional medicine left them with no hope. In the 1970s, Dr Ann Wigmore opened the Hippocrates Health Institute, in Boston, nourishing terminally ill patients back to health with fresh squeezed wheatgrass and from then on it has been an underground health story passed on by word of mouth.

Wheat grass has been called one of nature’s finest medicines. It is perhaps the most nutritious and cleansing juice there is. In its natural state, wheat grass is indigestible for humans; so don’t go plucking it straight out of the field. However, wheatgrass juice is easily digested and its nutrients and enzymes are quickly absorbed into the bloodstream, providing an instant boost of energy and ongoing nourishment. It is high in chlorophyll, potassium, calcium, and magnesium and is a highly effective detoxifier, especially for the liver and gallbladder. Wheat grass has nearly a gram of protein per teaspoon, and includes all eight of the essential amino acids, as well as 13 of the remaining 16. It contains Vitamins A, B1, 2, 3, 5, 6, 8, and 12; C, E and K. A teaspoon of wheat grass contains around 15mg of Calcium, 8mcg Iodine, 3.5mcg Selenium, 870mcg Iron, 62mcg Zinc, and many other minerals.

There is another good reason to take a daily shot of wheatgrass: it contains Superoxide Dismutase (SOD), and it has been found that cancerous cells have a deficiency, or a complete lack of, SOD. Anti-oxidants have the ability to mop up free radicals and so reduce or avoid cell mutation. Mutation is part of the first stage of cancer formation so, if you supplement your diet with wheat grass you will almost certainly be helping your body to avoid, or deal with, cancerous conditions.

You don’t have to drink gallons of the stuff either, the intense green juice is best taken in ‘shots’ of about 1tbsp at a time. Like all fresh juices it needs to be drunk immediately, it goes off in about 30 minutes, so cut from the tray and juice, or cut the shoots and keep in a plastic bag in the refrigerator where they will retain their nutrients for up to seven days after cutting.

For those with an intolerance to gluten, do not be put off because the grain metamorphoses completely into a vegetable, with none of the allergic proteins common to the glutenous grains. You can indeed follow the advice of Hippocrates, the father of medicine, who said “our food is our medicine and our medicine is our food”

Oh, and if you are not a gardener, even of the windowsill variety, then you will be delighted to learn you can actually buy the stuff ready grown, cut and ready to stuff in your juicer. Ask at your local health store as it can often be found as tablets or powder supplements and in bags in the chiller cabinet, or you can order trays of wheat, barley, oat and rye grass from this site: www.browfarmwheatproducts.co.uk

Whatever you do, start with small amounts as it is a powerful detoxifier and you can mix it with juice if you find the taste not to your liking.

How to lower stroke risk

Do you have plenty of asparagus, broccoli, Brussels sprouts, spinach, chick peas, oranges, wheat germ and kidney beans in your diet? If so, then you are naturally getting high levels of folate, which is a water soluble member of the B vitamin family, B9 to be exact. Folate is vital in protecting you against the risk of a cerebral infarction, the most common kind of stroke. In fact it accounts for 80% of all strokes, and so a recent study wanted to look at whether supplementing with vitamins, or increased intake of foods high in , could make a difference.

A dual study in Sweden and Finland have been looking at the relationship between folate, vitamin B6, vitamin B12 and the amino acid methionine – all of which are involved with homocysteine production. Why should they be interested in that? Because high levels of blood homocysteine are linked to increased stroke risk, and much interest is being shown in how to use supplements, and diet, in a more preventive way in healthcare.

The findings of the study are encouraging if you are at risk of a stroke: those with the highest intake of folate had a 20% lower risk of stroke than those with the lowest levels.

These findings are based on the subjects’ normal, everyday, diet. They were not given any supplements or asked to eat any differently with special foods. So if you have any incidence of strokes in your family, it makes sense to include as many of these foods as possible in your diet. I certainly have a family history and much as I dislike Brussels sprouts, I must try to love them – although I think it will be my asparagus intake that goes up first!

Flu vaccine not as effective for heart patients

Obviously if you have heart disease, or cardiac problems, then the focus is solely on keeping the heart healthy. However, a report presented at a meeting of the American College of Cardiology by Dr Orly Vardeny, of the University of Wisconsin seems to imply that “heart failure goes beyond the heart, that there are other systems challenged by the condition.” This arose from his study which indicated heart failure patients may not have as strong an immune response to flu vaccine as healthy patients. This is not the time of year to be thinking of flu vaccines, but I am a great believer in looking ahead and being prepared. The report showed that patients with heart failure had a significantly lower antibody response to one of the three influenza virus strains found in the flu vaccine used for the study, compared with healthy patients. It has been previously established that heart failure patients are at an increased risk for developing influenza, which is why yearly vaccination is recommended for them, but it was reported by Dr. Vardeny that there are still high numbers of hospitalisations and deaths from influenza in heart failure patients, They do not yet know why the impaired response happens but believe it may be due to increased neurohormone levels, such as norepinephrine and angiotensin II. Further study is being done on the specific effects of norepinephrine or beta-adrenergic mechanisms in response to vaccines, but they do not suggest that patients with heart failure should stop getting immunised just yet.

The answer might lie in more preventive measures such as boosting the immune system through natural means by methods such as meditation, exercise and supplements such as additional vitamin C and immune boosters like ginseng and Echinacea. Belt and braces has always been good advice if you are vulnerable to infections and if in any doubt, please talk to your doctor about how a flu vaccine might affect you.

Cholesterol – Keeping the balance naturally

If you watch television, or read magazines, you cannot miss the constant bombardment on the ‘evils’ of high cholesterol. Certainly, out of control levels of high cholesterol are to be avoided, but so too is low cholesterol. It is not the cholesterol itself that is ‘evil’; we actually require normal levels for the production of the hormones testosterone and oestrogen, and it is found in our cell membranes as part of the structure to keep them waterproof.

Without cholesterol, we could not have a different biochemistry on the inside and the outside of the cell. When cholesterol levels are not adequate, the cell membrane becomes leaky or porous, a situation the body interprets as an emergency, and then releases a flood of corticoid hormones to repair the damage.

Cholesterol is therefore essential as it is the body’s chief repair substance: scar tissue contains high levels of cholesterol, including scar tissue in the arteries. So you can see that so cutting out all cholesterol is actually a bad idea. Studies have shown that there is an increased risk of strokes and a compromised immune system when cholesterol drops too low, but as always the answer lies in balance.

If you do have high cholesterol then it can lead to hardening of the arteries and heart disease, but statin drugs, given for the inhibition of cholesterol, – as I have reported before – have their problems too. They have been associated with side effects such as muscle pain and weakness, memory loss, nerve problems and interference with production of Co-Q10.

Natural Solutions?

So, if you don’t want to take drugs to lower your cholesterol, what can you do? Back to the advertisers, who imply that by switching to their margarine, or yoghurt product, you can lower your levels naturally. Well, that depends on what you mean by ‘naturally’. If you read the labels on those products, they contain many chemical compounds, and the ‘healthy’ yoghurt drinks contain not only sugar but sweeteners as well.

So what else is left? Enter the humble grapefruit, wholly natural and a lot cheaper than buying the aforementioned products.

An international team of researchers from Israel, Singapore and Poland put grapefruit to an extremely rigorous cholesterol test. Researchers at the Hebrew University in Jerusalem, recruited nearly 60 subjects who had several things in common: they all had undergone recent coronary bypass surgery, had high cholesterol levels, and had used a cholesterol-lowering statin drug with no success. At the outset of the study, none of the subjects had taken any statins for at least 30 days and they were divided into three groups. Over the 30-day study, everyone followed the same low-fat diet, but one group ate one yellow grapefruit a day, while another group ate one red grapefruit daily. They all ate their normal, everyday diet and the third group got no grapefruit at all.

At the end of the study, the two groups who had eaten the daily grapefruit had lower levels of both total cholesterol and LDL – and it was even more marked in the group who ate red grapefruit. Another benefit seemed to be that triglyceride levels also dropped in the red grapefruit group, but not in the other groups. Triglycerides are blood fats that can leave deposits in coronary arteries, and so increase the risk of heart disease.

Now my problem is that my local supermarket has red, yellow and pink grapefruit so I might have to ask them for advice on whether ‘pink’ has a diluted effect from the ‘red’ benefits!

More Good Grapefruit News

Oh, and if you are wanting to lose some weight, there was a study at the Scripps Clinic in San Diego four years ago, in which a group of 100 obese subjects were told to stay on their normal diets, and in addition were given either grapefruit or grapefruit juice to have once a day. On average they lost 3lb, and one person lost 10lbs, as opposed to the non-grapefruit trial group who lost less than a 1lb.

Diabetics may also be interested to learn that the subjects in that same study also showed better management of insulin levels. Those in the two grapefruit groups had lower levels of insulin and glucose than they did at the outset, while levels in the non-grapefruit group were unchanged. The Scripps researchers believe that enzymes in grapefruit help control insulin spikes that occur after a meal, which frees the digestive system to process food more efficiently. This means that less nutrients are stored as fat.

Caution

Many foods can interact with the effectiveness or efficiency of drugs, and grapefruit are no exception. Chemicals in grapefruit interfere with the enzymes that break down certain drugs in your digestive system and this can result in excessively high levels of these drugs in your blood, and an increased risk of side effects. The following list is a generic overview of the classes of drugs that may be affected. Bear in mind that it may not be all drugs within a particular group, so consult with your doctor if you are taking any of the following types of medication:

Anti-seizure medication – anti-arrhythmia drugs – antidepressants – erectile dysfunction – Calcium channel blockers -HIV medications – HMG-CoA reductase inhibitors used to treat high cholesterol – Immunosuppressant drugs – Methadone Pain relief – Tranquillisers.

Computer vision – A new disease?

We are all spending more and more time in front of a computer; shopping online, checking emails, reading our horoscope (or is t hat just me?). It is easy to forget the time, but your eyes will remind you because hours spent staring at a computer screen means you risk suffering tired, dry eyes, blurred vision, eye strain, headache, and sensitivity to light. This has led to a new ‘disease’ being recognised, collectively those symptoms are becoming known as “computer vision syndrome.”

The American Optometric Association certainly has recognised it as a growing problem with an estimated 10 million people visiting their optometrist annually for computer eye-related difficulties. Apparently, according to the Optometric Association, a computer is a challenging environment for the eyes because the imagery is not as clear as it seems to be, and because of that it’s harder for the eye to focus than it would be on ordinary print on a page.

First step is to get your eyes checked and if you spend more than a couple of hours a day in front of the computer you should mention it to your optician so they can see whether you need separate glasses for that, or a screen filter to help reduce glare and eye discomfort. If you wear bifocals, or varifocals, you can also suffer from neck and shoulder problems because these glasses are often not set for the computer so you end up having to move your head closer to the computer while at the same time tipping your head back to see the screen. That’s an awkward position and if you have been suffering from a stiff neck it could be the reason why.

One simple tip that helps is to blink more often because that lubricates your eyes. When we concentrate, our blink rate goes down, leading to dry eyes. Try adopting the 20/20 rule – every 20 minutes look away from your computer for about 20 seconds; this will minimize the development of eye-focusing problems and eye irritation caused by not blinking enough.

Check the lighting, you don’t want too much bright overhead light or any kind of glare or reflection off your computer screen. Finally, is your monitor at the right height? Experts advise that for maximum ergonomic comfort, the screen should be right in front of you so you don’t have to twist to see it and the monitor should be at eye level, or a little below it.

Can’t sleep? Women at risk

Yesterday it was reported in Brain, Behavior, and Immunity that women with sleep problems have higher levels of biomarkers for cardiovascular disease and diabetes than do men who can’t sleep. Poor sleep patterns in this instance is defined as problems falling asleep, taking 30 minutes or more to fall asleep, or awakening frequently. Apparently, researchers at Duke University found that such women also have greater psychological distress than men who sleep poorly. The difference in gender risk is marked, as when comparing men and women with the same poor sleep patterns, they found that the women had high levels of C-reactive protein, interleukin-6, and insulin, leading to higher risks of cardiovascular disease and hypertension.

The women who had the biggest risk were those who took over half an hour to fall asleep, so if this is you it could be time to look at alternative methods to aid sleep such as camomile tea, valerian or a warm, not hot, bath with lavender oil before going to bed. If those simple methods don’t help, then you might also consider looking at these factors:

Are you a late night snacker?
Avoid anything containing grains and sugars (biscuits, cakes, bread, crackers) before bedtime as they will raise your blood sugar and inhibit sleep. Later, when your blood sugar drops back to a lower level then you might wake up and not be able to get back to sleep.

Is your bedroom dark enough?
If there is even the tiniest bit of light in the room it can disrupt your circadian rhythm and your pineal gland’s production of melatonin and seratonin. If you get up in the night to go to the bathroom then try and keep any light to a minimum because as soon as you turn on a light your body responds and immediately ceases all production of the important sleep aid melatonin and doesn’t recommence that night at all.

Late night tv watcher?
Watching tv right before bed is too stimulating to the brain and it will take longer to fall asleep. If you must watch, stay in the living room and don’t have set in your bedroom. Watching tv in bed is also disruptive of pineal gland function for the same reason as light in the bathroom/bedroom.

Cold feet?
Because our feet have the poorest circulation, they often feel cold before the rest of the body. A study has shown that wearing socks to bed reduces the possibility of you waking through feeling cold.

Chocolate treats – But don’t eat them

Easter is upon us, and the array of chocolate stretches to infinity and beyond, but not everyone can eat chocolate – or indeed wants to.

If you are, or know, someone like that then can I suggest a couple of healthy alternatives – and no it is not carob, because however virtuous carob may be, it cannot be a substitute for chocolate. I have yet to think what it might be a substitute for, but give me time.

First, let me commend you to those wonderful people at Lush who hand make a range of beauty treats from all-natural ingredients at incredibly low prices. The two you might want to consider as gifts are: Soft Coeur – if you don’t’ have elementary French, think Soft Heart or as the wonderful Lush Times describes it,’The Honeymooner’.

If you are looking for a messy massage bar made from honey, cocoa and natural butters this is a real treat – just don’t forget to massage with it and not masticate it.

Secondly, the other product of theirs I can highly recommend is the Cupcake facemask, which is recommended for oily, congested, skin. Something you might well have if you have over indulged in the real chocolate Easter treats. It is an anti-microbial cleansing mask made from Rahassoul mud – which gives it the chocolaty colour from which it takes its name, and sandalwood, spearmint and peppermint oils to give your skin a boost. Buy from their stores or online at www.lush.com.

Finally, there is a great craze for raw chocolate at the moment, and one way to get your fix is with another face pack, this time from organic skin care company Raw Gaia. They have launched the world’s first raw chocolate face pack and like all their products it is hand made, organic, vegan and cruelty-free. It contains raw chocolate powder, the highest known source of antioxidants in the world, plus red clay, organic turmeric and organic amla (an Ayurvedic herb) fruit powder.

The nutritional content of raw chocolate powder is amazing: there are over 25,200 antioxidants in a single spoonful of the stuff and raw chocolate powder contains 367% more antioxidants than its cooked version. You can buy it from good health food shops or online from Gaiaa. It costs £8.20 for 50grams and won’t put a single extra ounce of weight on your hips – honest. www.rawgaia.com.
