Calcium Supplements Risk for Heart Problems

If you have been taking these to help your bones, there is a hidden danger that has been exposed by new research in the British Medical Journal which adds to mounting evidence that calcium supplements increase the risk of cardiovascular events, particularly heart attacks, in older women.

Nutritionists have been saying for some time that calcium supplements alone are not a good idea, but these new findings suggest that their use in managing osteoporosis should be re-assessed. They are often prescribed to older (postmenopausal) women to maintain bone health and sometimes they are combined with vitamin D, but there are a whole range of heart supplements that are needed, not just calcium alone.

A team of researchers, led by Professor Ian Reid at the University of Auckland, re-analysed a seven-year trial of over 36,000 women to provide the best current estimate of the effects of calcium supplements, with or without vitamin D, on the risk of cardiovascular events.

What they found was that the women who were not taking personal calcium supplements at the start of the trial but then were given a combined calcium and vitamin D supplement were at an increased risk of cardiovascular events, especially heart attack. By contrast, in women who were taking personal calcium supplements at the start of the trial, combined calcium and vitamin D supplements did not alter their cardiovascular risk.

The authors suspect that the abrupt change in blood calcium levels after taking a supplement causes the adverse effect, rather than it being related to the total amount of calcium consumed. High blood calcium levels are linked to calcification (hardening) of the arteries, which may also help to explain these results. The authors concluded that these data justify a reassessment of the use of calcium supplements in older people.

If you do want to keep your bones strong, and not impact your heart, then gentle regular weight bearing exercise is a start, and add plenty of black pepper to your diet as it contains four anti-osteoporosis compounds and boron, which is also good for bone health, is found in abundance in cabbage. Also healthy for bones are garlic, onions and eggs plus cod liver oil A which is a natural source of vitamins A and D3. If you do want to take a supplement look for one with a good mix of bone building nutrients including vitamin D, calcium, magnesium, silica and boron. Higher Nature make a good one called Osteo Food and the best natural way to build bone is to have good levels of progesterone as that is the first bone-building substance the body needs.

What Can Double or Triple the Risk of DVT’s for Women?

The risk of blood clots and DVT’s are well publicized in relation to air travel, but what you may not be aware of is that just prolonged sitting around at home or the office can also be potentially life threatening – particularly for women.

New research published in the British Medical Journal (BMJ) shows that although the greatest risk factor for deep vein thrombosis (DVT) is surgery, most people associate it with long-haul flights and the Pill but they could be tragically mistaken. The amount of time spent sitting every day – wherever you are – means you could be putting yourself at risk of developing potentially life-threatening blood clots.

This study was done in the USA, and found that women who sat for a long time every day had double or even triple the risk of a dangerous blood clot in the lungs.
While the women most at risk had sat for more than 41 hours a week (on top of their work hours), the research is the first to prove a sedentary lifestyle increases the dangers.

DVT is caused when the wall of a blood vessel is damaged through injury, such as a broken bone or surgery, or if the blood clots more easily than normal as a result of medication or genetics. They fact here though is that it can also be triggered by the blood flow slowing down considerably — such as when you’re immobile for a long time through lying or sitting down.

What Can Help?
First of all realistically monitor how much time you do spend sitting down and reduce it in simple ways. First of all bin the TV remote and get up to change channels, if you work at a desk or on a computer get up every hour and just move around for five minutes. If you have the choice of stairs or a lift, use the stairs for at least part of the way.

When travelling try to drive no more than two hours without a break, even if you just pull into a car park and walk round it for a few minutes. By air, it is not now frowned on to get up and walk round the plane, though your way may not always be clear it is worth the effort to avoid the duty free carts or if stuck in your seat try tensing and releasing the muscles in your buttocks, legs and feet. By curling or pressing the toes down, which causes the muscles to contract and squeeze on the leg veins, helps to pump the blood along. Another way to help move blood to the heart is to wear compression stockings, which put gentle pressure on the leg muscles as studies in healthy people have shown that wearing compression stockings minimizes the risk of developing DVT after long flights. Avoid socks, or knee highs for women that have very tight elastic bands at the top and do not sit with your legs crossed for long periods of time, which constricts the veins.

Keep the fluid flowing:
Sorry, not alcohol but you need to drink plenty of fluids to prevent dehydration as this causes blood vessels to narrow and blood to thicken, increasing the risk for DVT. Reducing alcohol and coffee consumption, which both contribute to dehydration, is also recommended.

If water is not your thing there is also a new fruit juice which has been proven to benefit blood circulation. Sirco™contains a tasteless tomato extract, Fruitflow®, that has been scientifically proven to have heart and circulation health benefits because in several clinical trials it has been shown to help maintain a healthy blood circulation by preventing the “clumping” of blood platelets which can lead to blood clots. The blood platelet smoothing action of Sirco™ takes effect within 1 ½ to 3 hours from drinking it and lasts up to 18 hours and is suggested as a natural alternative to a daily aspirin that many people take for this action. It fits well into the healthy Mediterranean diet eithos and comes in two 100% pure fruit juices mixes; Pomegranate/Orange and Blueberry/Apple.

Olive Oil Lowers Stroke Risk by 40%

July 18, 2011 by  
Filed under Food & Nutrition, Health

Last week I was encouraging you to eat more strawberries and now continuing the healthy summer diet theme I would like to see you pouring out more of the golden liquid – preferably cold pressed and organic. New research shows that regular olive oil consumption lowers stroke risk and by a highly significant amount, particularly in the elderly.

Critical research released in the journal Neurology from the American Academy of Neurology provides evidence that regular consumption of olive oil can help to do more than keep your heart healthy. The value of the Mediterranean diet is now well proved but this new study study examined individuals over the age of 65 that are most vulnerable to the devastating effects of a stroke. Scientists suggest that olive oil taken as part of a healthy diet can lower the life-altering risks associated with a stroke by 41% in the elderly. Based on this body of work, researchers “suggest that a new set of dietary recommendations should be issued to prevent stroke in people 65 and older.”

The study author was Dr. Cecilia Samieri from the University of Bordeaux in France and she and her researchers examined the medical records of 7,625 aging adults 65 or older from three cities in France. These were in generally good health and had no prior history of stroke. Participants were monitored via a dietary questionnaire to record how much olive oil they used and then that was broken down into three groups: none, moderate and intense which was based on their regular consumption habits. Because this was a home, not a laboratory trial they were assessing not just their consumption but the type of oil they used at home and it is significant to note that virtually all of it was extra virgin and cold pressed. This type of minimally processed oil is what is recommended to combat heart disease and has been previously found to lower the risk of heart disease in prior studies. Extra virgin olive oil is known to be a rich source of natural polyphenols from the olive fruit; it alters the oxidized, sticky nature of LDL cholesterol that is implicated with plaque build-up in the arteries.

This was a long term study as they followed the participants for a period of five years, and 148 strokes occurred during that time span. After considering dietary, lifestyle and medical history, researchers found that those with the highest intake of extra virgin olive oil were 41% less likely to suffer a stroke compared with those with the lowest consumption of the monounsaturated oil. In a secondary arm of this study where plasma fatty acid measurements were available, individuals with the highest oleic acid (olive oil fraction) were found to experience a 73% lower risk of stroke.

Olive oil consumption is associated with lowered risk of cardiovascular disease, diabetes, high blood pressure, lipid abnormalities and obesity and now strokes can be added to the list. Dr. Cecilia Samieri commented, “Stroke is so common in older people and olive oil would be an inexpensive and easy way to help prevent it.” The study did not specify the amount of olive oil used by those in the `intense` group that experienced the highest degree of protection from stroke but nutritionists recommend that most people should add 1 to 2 tablespoons of extra virgin olive oil five days a week to reap the powerful health benefits of this monounsaturated oil. Be generous with the olive oil in your salad dressing, and personally I add my salad dressing to hot vegetables as well, particularly good on carrots!

Infertility Linked to Cholesterol Gene in Women

July 13, 2011 by  
Filed under Health, Womens Health

This gene also affects progesterone production and may be the cause of infertility in a substantial number of cases of infertility. This breakthrough comes from a new study by researchers at Johns Hopkins University School of Medicine in the US and published online in the journal Human Reproduction.

The gene responsible is the scavenger receptor class B type 1 gene (SCARB1) and this new research follows up studies in female mice that first linked a deficiency in these receptors for HDL — the so-called “good” or “healthy” cholesterol — and infertility. Now researchers report finding the same link in studies of women with a history of infertility when they analyzed ovarian cells and fluid collected from 274 women unable to become pregnant for various reasons and undergoing in vitro fertilization (IVF).

Endocrinologist Annabelle Rodriguez, M.D., an associate professor of medicine at Johns Hopkins in the USA said “Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility.” She believes the genetic variation could be present in 8 to 13 percent of the population and that means potentially being able to help a substantial number of women.

They researchers have also developed a simple blood test for this variation of the gene involved, but this knowledge has not so far led to any approved therapy though it would seem logical to ensure that a woman’s progesterone levels are healthy and balanced before looking to start a family.

Salt Is Not Always A Negative Health Factor

July 12, 2011 by  
Filed under featured, Health

Salt, like butter, has become a bit of a ‘health demon’ in recent years – though not by me. Obviously drowning your food in salt is not a good idea health wise – or taste wise – but in moderation I don’t have a problem with it and now new research backs that up and indicates it can be just as dangerous to have a low intake.

Salt In Pregnancy:
The link between high salt intake and high blood pressure is well established, but a new study published in the American Journal of Physiology has found that consuming too little sodium is also damaging. According to researchers from both the University of Heidelberg in Germany and the University of Aarhus in Denmark, women who consume too much or too little sodium during pregnancy can end up with children with poorly-developed kidneys, which in turn can cause a lifetime of heart problems.

Building upon previous studies that identified a link between excessive sodium intake and low birth weights, high blood pressure, and kidney problems, the new study identifies similar developmental deficits from too little sodium intake. Mothers who had both too little, and too much, were affecting their babies development during between the crucial developmental period of 1 – 12 weeks. Principally, this concerned the kidneys and ability to carry out their vital function of filtering the blood and creating urine waste.

If you are concerned about diet in pregnancy then there is an excellent website which gives good information provided by the British Nutrition Foundation. It is a free online resource for parents and health professionals at www.nutrition4baby.co.uk.

Salt In Adulthood:
If you have been virtuously ‘passing’ on the salt to reduce your risk of heart disease then the bad news is it won’t have made any difference. The good news is that a sensible amount won’t reduce your chance of dying early.

A systematic review of nearly six and a half thousand patients, published in the latest edition of The Cochrane Library, has shown that a moderate reduction in the amount of salt you eat doesn’t reduce your likelihood of dying or experiencing cardiovascular disease.

In the UK, the National Institute of Health and Clinical Guidance (NICE) has recently called for an acceleration of the reduction in salt in the general population from a maximum intake of 6g per day per adult by 2015 to 3g by 2025 and most food manufacturers are working to remove it from their products so your intake is being gradually reduced by external circumstances.

So which salt is best?
Moderation seems to be the key – as it is with most health food issues – and it’s really important to know that not all sodium is the same. The ones to avoid are processed table salt and chemical salt derivatives like monosodium glutamate because these are the true culprits that bring about heart disease.

The best option is to go for full-spectrum sea and mineral salts like Himalayan Pink Crystal Salt as these contain beneficial trace minerals and elements that are vital to health.

Got Diabetes? – Eat More Strawberries

Wimbledon may be over, but we are still in the wonderful English strawberry season and now there is a powerful health reason to eat more of them. A recent study from scientists at the Salk Institute for Biological Studies suggests that a strawberry a day could lessen the complications of diabetes. Or more accurately, the fisetin they contain as this naturally-occurring flavonoid is found most abundantly in strawberries.

Fisetin is a naturally-occurring flavonoid found most abundantly in strawberries, and to a lesser extent in other fruits and vegetables, and has been found to be able to target multiple organs. This research describes for the first time a drug that prevents both kidney and brain complications in a type 1 diabetes model and strongly suggests that a single drug could be used to mitigate numerous medical complications.

Fisetin was originally identified as a neuroprotective flavonoid ten years ago and in plants it act as sunscreen and protects leaves and fruit from insects. The types of fruit and vegetables containing fisetin are found in the ‘Mediterranean Diet’ and contribute to the protective effect of that regime.

The researchers evaluated effects of fisetin supplementation with reference to the serious complications of diabetes such as diabetic nephropathy or kidney disease, retinopathy, and neuropathies in which patients lose touch or heat sensations. Improvements were seen, but remember that to achieve a similar effect you would need to eat 37 strawberries a day so let’s hope they manage to turn the fisetin into a supplement form fairly soon.

Interestingly, the fisetin was also effective in mouse models of Alzheimer’s disease so there is certainly more research to be done.

In the meantime what about a strawberry and blueberry smoothie to get the maximum fisetin into your system in a palatable way?

A New Way to Tackle Snoring

July 6, 2011 by  
Filed under At Home, Health

I sometimes think that true love is the ability to sleep through the gentle whistle, or grinding gears of your partner’s snores, but if it gets too much for you there is a new solution that might help.

Asonor® is a new anti–snoring product that has already successfully helped 75% of snorers in Europe, and was recently ranked no.1 in an independent user test by a Scandinavian health magazine. I don’t know if Swedes are heavy duty snorers, but given that apparently 1 in 4 of us snore (yes, us too, ladies) and that a recent survey found that 1 in 5 couples sleep in separate bedrooms because of it any help is welcome! As it also seems that 57% of people think that snoring has caused arguments or tension in their relationship, and snoring has also been linked to health problems such as obesity, high blood pressure and cardiovascular disorders there is no reason to delay in tackling it.

Asonor® directly targets the primary cause of snoring, which of course is the throat. It works by delivering a gentle stream of solution via the nasal passage to lubricate the soft palate and lightly tighten the musculature of the throat. By targeting the primary cause of snoring, rather than staying in the nose like other spray snoring remedies, asonor® also significantly reduces interference with breathing.

Sadly, this is not a one off solution, to really tame the snore(r) asonor® should be taken consistently, in each nostril every night before bedtime until the desired effect is obtained, normally within two weeks.

S(ummer) Affective Disorder

July 5, 2011 by  
Filed under Health

You may have heard of the winter equivalent, but this is a new one on me. However it just so happens that I may be one of the few who does not look forward to summer and are generally much happier in the autumn and winter months.

This summertime mood disorder was first recognized as a form of depression in 1986 and is thought to affect less than one percent of the population, making it much rarer than the winter variety experienced by an estimated 5 percent of people. If you suffer from SAD then your symptoms mean you sleep less, eat less, and lose weight and are extremely irritable and agitated.

Dr. Norman Rosenthal, a clinical professor of psychiatry at Georgetown University Medical School, who has studied both types and first helped discover their existence believes that people with summer seasonal depression may be more at risk for suicide than cold-weather SAD types. He said “Suicide is more of a concern when people are depressed and agitated rather than depressed and lethargic.”

Rosenthal also said that mental health professionals suspected the cause was the heat and humidity. That, he said, lent itself to the idea that a cold shower, air conditioning, swimming in cold lakes or heading North would relieve symptoms. Although these treatments for hot-weather depression are useful for some, they lack the staying power that light-box therapy has on winter SAD.

Rosenthal is the author of “Winter Blues” and says that a person with summer SAD can stay inside, crank up the AC, and darken the room but then go outside into the heat and it’s as if they’ve never been treated. Another idea is that it might be the light itself that’s aggravating sufferers, whether it’s the intensity of sunlight or the angle it’s coming at people.

Still another possibility is that there may be two kinds of warm-weather depression, says Dr. Alfred Lewy, a professor of psychiatry at Oregon Health & Science University in Portland. He suggests there might be one group of people who have an unpleasant reaction to the heat and humidity — a discomfort with the climate. But even in Portland where summers aren’t that hot or humid, he’s seen patients struggle with summer depression. Lewy suspects the cause in a second group might be that the body’s natural clock, it’s circadian rhythms, are misaligning in summer. Instead of cueing to dawn, the longer daylight is causing some vulnerable people to cue to dusk. Cueing to dusk shortens the typical body clock and delays a person’s sleep-wake cycle. This mismatch, theorizes Lewy, may be triggering depression.

He successfully treated a person with summer depression with a combination of getting early morning sunlight (30 to 60 minutes daily), which shifts the body clock forward, and low-dose melatonin, a hormone that helps regulate sleep-wake cycles. Severe symptoms may also benefit from antidepressants.

I am alone with this, or are there other Summer AD’s out there?

Doctors Warn of Dangers of Energy Drinks for Children

July 4, 2011 by  
Filed under Childrens Health, featured, Health

There are times we all need a pick me up, and with the young – particularly teenagers the new energy drinks are a fast fix. Usually full of sugar, caffeine and other ingredients such as ginseng and taurine they are easily available and very attractive to the eye. However, in a new report, experts are now urging children and teenagers to avoid them because of possible health risks.

“Children never need energy drinks,” according to Dr. Holly Benjamin of the American Academy of Paediatrics who worked on the new report. “They contain caffeine and other stimulant substances that aren’t nutritional, so you don’t need them.” Experts fear that kids are more vulnerable to the contents of the drinks than adults because if you drink them on a regular basis, it stresses the body. You don’t really want to stress the body of a growing person.”

The report speaks of the jumble of ingredients in the energy drinks which include vitamins and various herbal extracts which could have potential side effects that are not yet entirely understood. The report acknowledges that while there are not many documented cases of harm linked directly to the drinks, the stimulants contained within can disrupt the hearts rhythm and in some rare cases can lead to seizures.

Benjamin states that she recently saw a 15 year-old boy with ADHD who came to the hospital suffering from a seizure after drinking two bottles of Mountain Dew, a soft drink containing caffeine. The boy had also been taking stimulant ADHD medications and perhaps the combination of the drug and the extra caffeine had pushed him over the edge.

Which Foods Will Give You Most Weight Gain – and Loss?

June 29, 2011 by  
Filed under featured, Food & Nutrition, Health

This is one of those studies from the US that will either cheer you enormously, or cause you to rethink your shopping trolley. It seems that the humble potato crisp may be the most dangerous food for your hips.

The man responsible for this – and other news – is Dariush Mozaffarian, MD, DrPH, of Brigham and Women’s Hospital and Harvard Schools of Medicine and Public Health in Boston, Massachusetts. He has laid out weight-associated foods by the pound and has calculated that roughly half of the average 3.35 pounds a healthy, non-obese American gains over four years could be chalked up to eating more potato crisps – though he doesn’t say exactly hw many so does one small bag of Smith’s non-salted really count?!

His results were reported in the June 23 issue of the New England Journal of Medicine and the foods most strongly associated with weight gain are these:

• Potatoes
• Sugar-sweetened drinks
• Unprocessed red meats
• Processed meats
• Alcohol

What is interesting to me is that there is little difference in his analysis between processed and unprocessed meats, but if you are looking to lose some pounds then over a four-year period the most weight loss was associated with these foods:

• Yogurt
• Nuts
• Fruits
• Whole grains
• Vegetables

This pretty much follows the well-known data that a vegetarian/vegan diet will generally help you lose weight and be healthier all round. In fact as we age, and tend to put on weight, such a diet may have only a slight creeping gain of 0.8 lb on average per year.

Two non-food items that will put on the weight are giving up smoking and too much television watching. If either of these is a factor for you then not surprisingly, physical activity will help you lost some of that extra weight effectively and healthily.

A Healthy Alternative:
If you want a savoury snack, then instead of crisps what about a brand new concept? Savoury Veatable bars are eaten fresh from the fridge and are soft and chewy. They only have 99 calories per bar and although I have to say I was not keen on the idea, once I tried one my favourite was the Tomato Pizza version which contains tomatoes blended with onions, cheese olive oil and mixed herbs and really was very tasty.

You might prefer the other two varieties: Roasted vegetable or Thai Sweetcorn. They are made from diced and roasted vegetables, 100% natural, gluten and wheat free, high in fibre and count as one of your five a day.

You should find them in health stores, or direct from www.veatable.co.uk.

And if you are serious about weight loss, make sure you get a good night’s sleep as a lack of it can slow the rate at which you burn calories, increase blood sugar levels and make you feel hungrier. Researchers at the University of Chicago recently studied a group of dieting men and women, some of whom had 8.5 hours sleep a night, the others just 5.5 hours, they found that those that got adequate sleep lost over 50% more weight than their sleep-deprived counterparts.

Time for a snooze, then?
