Diet Drinks Can Increase Your Waistline and Put Weight On

During the summer we naturally consume more drinks to help with dehydration, and diet drinks are certainly popular for both refreshment and in the mistaken belief they help you lose weight. I say mistaken advisedly as a new study has shown that diet drinks actually cause weight gain and blood sugar spikes.

These diet drinks are made with artificial sweeteners like aspartame and a landmark new study out of Texas confirms that not only do diet drinks not help with weight loss, but they actually cause both weight gain and health problems.

Researchers from the University of Texas Health Science Center (UTHSC) at San Antonio gathered ten years worth of data on 474 participants from a larger, ongoing study called the San Antonio Longitudinal Study of Aging. Among these participants, those that consumed two or more diet drinks a day experienced waist size increases that were a staggering six times greater than those who did not consume diet drinks.

Helen P. Hazuda, a study researcher and professor at the UTHSC School of Medicine presented the study results at the annual meeting of the American Diabetes Association. She reported that: “Data from this and other prospective studies suggest that the promotion of diet sodas and artificial sweeteners as healthy alternatives may be ill-advised. They may be free of calories, but not of consequences.”

The findings debunk the false notion that switching to diet drinks will help you lose weight. What they do show is a 70 percent increase in waist size compared to those who do not drink them, so it is not clear how calling them ‘diet’ is applicable.

I have mentioned the health dangers of aspartame before, and a related study presented at the same time, found that this chemical sweetener commonly found in diet foods and drinks, is actually responsible for raising blood sugar levels.

This was an animal, not human study, but the results suggest that heavy aspartame exposure might potentially directly contribute to increased blood glucose levels. This could be a major contributory factor to the risk of diabetes, already a worldwide epidemic and growing.

A previous study had linked saccharin to weight gain and according to Dr. Marie Savard, medical contributor for ABC News, there is something about diet foods that changes your metabolic limit, your brain chemistry.The truth is, we’re putting artificial sweetener in so many different things: in water, in yogurt. We have to rethink what this artificial stuff does to us.”

This links to a previous 2010 study conducted by researchers from the National Institute of Diabetes and Digestive and Kidney Diseases that found that the body’s reaction to the ingestion of artificial sweeteners appears to be brain confusion over how exactly to process it, which in and of itself is implicated in causing various other negative consequences.

Certainly it is true that US Food and Drug Administration have had adverse event reports going back several decades that indicate that artificial sweeteners like aspartame are also responsible for destroying brain neurons, which in turn leads to a host of chronic illnesses. These include, but are not limited to, chronic headaches, seizures, strokes, vascular disorders, heart disease, premature birth, dementia and other brain disorders, and cancer.

So if you want a fizzy refreshing drink then please steer clear of diet ones, and for a low calorie option try sparkling mineral water with a few drops of vanilla essence in it for sweetness and flavor.

West Highland White Terriers Could Help Your Health

Westies, as they are popularly known, are an attractive breed and got a media boost when featured in the Hamish Macbeth tv series, but it seems they may well be man’s best friend in more ways than one as they may hold the aswers to similar human diseases.

The Westie Foundation of America (WFA) has announced preliminary findings in two major studies involving the health of West Highland White Terriers and findings in these and studies of other dogs may hold answers for similar human conditions like Inflammatory Bowel Disease (IBD).

In one study, researchers are looking at the role of a mucosal gene driving inflammation Canine IBD, a chronic intestinal disorder that creates a bacterial-driven inflammation in the intestines. In the second, scientists are researching Legg-Calve Perthes Disease (LCPD), a debilitating developmental disease that causes pain, lameness and muscle atrophy of the dogs’ hip joints. Both are considering implications for humans since the diseases share commonalities in disease symptoms and pathology.

In IBD, genetic factors are thought to contribute to the cause of the disease in both dogs and humans and researchers are utilizing unique molecular biology tools to identify key genes which regulate intestinal inflammation, similar to human IBD.

Albert E. Jergens, DVM, PhD of Iowa State University is the study’s lead investigator and he explains: “It is our expectation to identify specific genes which serve as biomarkers for diagnosing canine IBD and for monitoring the effects of therapy. We have now identified a grouping of 17 ‘marker’ genes that may be more critically assessed in future studies. We have preliminary evidence that changes in the composition of the intestinal bacteria accompany the abnormal gene patterns…this situation is remarkably similar to the association between people and their intestinal populations causing human IBD (i.e., Crohn’s disease and ulcerative colitis).”

LCPD is an orthopedic disease that may require surgery to relieve the clinical signs and researchers are using technology to assess nearly 127,000 points in the dog genome. The goal of this project is to identify genes that contribute to the development of LCPD. Preliminary study findings show LCPD may be inherited in much the opposite way previous studies have shown. Earlier studies suggested LCPD is transmitted in an autosomal recessive pattern but the current data suggest it is inherited in either a dominant or complex fashion. The investigators currently have samples from 58 Westies, 23 of which have LCPD and more research is needed with the results of the candidate gene analysis to be published later this year.

Dogs are used in healthcare in other ways, as hospital visitors for instance where their presence is known to have a calming effect on patients and reduce their blood pressure but that they might help us get a cure for disease and hip disorders is certainly a step beyond that. If you have a Westie then perhaps an extra chew or toy as a thank you might be appropriate on behalf of his/her American relatives?

The Dietary Way to Avoid, or Reverse, Type 2 Diabetes

It is estimated that by 2050 as much of thirty percent of the American population could suffer with diabetes and usually where they lead we in the UK do tend to follow. As new studies show that diabetics also have nearly double the risk of cancer compared to the rest of the population it seems only sensible to be proactive and diet is the first and simplest step on that road.

All of the following have been shown to help prevent diabetes so stock up your larder and add them to your regular shopping list:

• It may seem odd that a sweet substance is on the list, but maple syrup can protect against both diabetes and cancer and contains a newly identified substance called Quebecol, formed when the sap is boiled, and is full of antioxidants.

• Ayurvedic medicine has long suggested the use of spices that offer some protection against diabetes: turmeric, curcumin and fenugreek. All are found in Indian cooking so makek a weekly date with your favourite restaurant or take away.

• The link between obesity and diabetes has been challenged by a recent study involving the Yup’ik people of Alaska where 70% are classified as obese, but only 3.3% of them have diabetes. The key may be in consuming indicates that consuming the type of fish rich in omega-3 fatty acids such as mackerel, salmon, lake trout, herring, tuna and salmon.

• A 2006 Italian study found that dark chocolate reduces the risk of insulin resistance, but the best comes from raw, unprocessed cocoa without any refined sugars added so minimal processing and maximum cocoa content is the key here with cocoa powder and baking chocolate containing the highest levels of the protective flavonoids.

• Coffee, in moderation, increases blood levels of testosterone and oestrogen. These hormones have long been thought to play a role in the development of type 2 diabetes.

• Polyphenols, the natural chemicals found in red grape skin and red wine, help the body regulate glucose levels, preventing potentially dangerous plunges and surges in blood sugar levels – same advice as for chocolate – in moderation!

• Phytochemicals – naturally occurring antioxidants – found in blueberries, cranberries and strawberries can also reduce your risk of diabetes, with the added benefit of helping you lose belly fat, according to a 2009 University of Michigan Cardiovascular Center study.

• Cherries are abundant in natural chemicals called anthocyanins, which increased insulin production in animal pancreatic cells by 50% in laboratory trials. Other sources include strawberries, red grapes and blueberries.

• Red and black beans can help regulate blood glucose and insulin levels so can help prevent diabetes, or minimize its effects if you are already diagnosed.

• Coconut oil has smaller, easily absorbed medium chain molecules that supply the cells with essential fatty acids without glucose and without inhibiting insulin production.

• Almonds and walnuts prevent diabetes by regulating blood glucose, particularly if eaten before a meal as that can help regulate blood sugar levels, and regular consumption did improve insulin levels in a 2009 study.

• Buckwheat helps control blood sugar levels and in an animal trial t heir glucose levels went down by twelve to nineteen percent. Easier to find as Japanese soba noodles in the supermarket.

• Cinnamon provides antioxidants and the powdered bark is also effective against diabetes. It improves blood sugar regulation by significantly increasing your glucose metabolism and has insulin-like effects in the body. Proanthocyanidin, a bioflavonoid found in cinnamon, changes the insulin-signalling activity of your fat cells.

• Tea: Green tea lowers blood sugar levels in type 2 diabetics and reduces associated complications such as cataracts and cardiovascular disease Black tea contains polysaccharides, a type of carbohydrate that includes starch and cellulose, that may benefit people with diabetes by slowing glucose absorption. A Scottish study found that natural chemicals found in black tea may protect against diabetes by mimicking the effects of insulin in the body.

• Seaweed, in the form wakame, helps promote fat-burning protein and promotes the synthesis in the liver of DHA (Docosahexaenoic Acid), a fatty acid also found in fish oil. It is also said to help prevent prostate cancer, support thyroid function, and assist in blocking the growth of breast cancer tumours.

Some of these changes are easy, others may be harder, but if you vary your diet and expand your culinary horizons you will definitely reap the benefit. Eating out from India to Japan and China won’t be too hard will it?

A Tastier Green Tea Option?

You know how fond I am of green tea for all its many health benefits – and if you are trying to lose weight then it is helpful in that area as well as taking care of your heart – but I know many of you don’t find it entirely palatable. Happily, there are ways around it from adding lemon and honey to finding a tea which has a taste you enjoy and I might have just the thing for you that comes from Vietnam.

If you have ever visited that country then you may have been given Vietnamese lotus tea – a type of green tea flavoured with the scent of the Lotus Flower. It is a specialty product of the Vietnamese tea industry and drunk as part of celebratory events or festivals as it seen as something rather special. The unique floral taste adds a whole new dimension to green tea and if you are fond of jasmine tea after a Chinese meal then it could hit just the right spot for you.

The traditional way to produce Lotus Tea involves using only the stamen of the Lotus flower and infusing it with green tea leaves and although there are several modern versions of the tea on the market now they are using flavourings or perfumes. For the authentic taste of Vietnamese lotus tea you need the actual ingredient, not a flavour, and that has become available in the UK for the first time from Natural Boutique.

They have a wide range of health giving teas, including an Artichoke tea which helps digestion and a rare and exotic Green and Java tea for aiding weight loss. If you can’t find Natural Boutique’s Vietnamese Lotus Tea in your local health store then visit the website at www.drinkherbaltea.co.uk.

Smoking Does Not Keep You Slim – But There Is a Male/Female Difference

There are many health myths that we hold as truth: the last biscuit on the plate contains no calories, my grandfather drank a bottle of whisky every day of his life and died at 101 so alcohol won’t harm me and perhaps the most common is that smoking helps keep you slim so giving up means becoming hugely overweight.

In one of my previous jobs I was Press Officer to Northern Ballet and bizarrely as it seemed to me most of the dancers smoked. You would think needing the best stamina and lung capacity would militate against it but, particularly for the girls, it was seen as an easy way to suppress appetite and control weight.

Now new research from the Nordic School of Public Health (NHV) in Sweden shows that smoking doesn’t help you get thinner, despite what we may believe. While cigarette smoking has decreased in western countries, obesity has increased and recent studies have suggested that today’s smokers may have less weight problems than non-smokers. Lisa Webb, Master of Public Health at NHV, set up a study in which over 6,000 people have participated in a study on the relationship between smoking and obesity.

They used two measure of body fat: BMI (body mass index) and WHR (waist hip ratio) and what surprised them was the definite difference between the results for men and women. Compared with non-smoker, both male and female smokers had a higher WHR but women had a lower BMI.

So if you are looking to use not giving up smoking because you don’t want to put on weight, then that is no longer viable. One other interesting finding was that the difference between the WHR among female smokers and women who had never smoked actually increased during the study. So if you want to improve your waist hip ratio then giving up smoking will definitely improve your chances of that.

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%

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

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

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.
