These cells are vital in terms of blood vessel function, controlling the ability of the vessel to contract and dilate to keep blood flowing in the body. Any trouble for these cells increases the risk of high blood pressure and a number of other health problems according to researchers.

High blood pressure is often called the “silent killer” because early on there are no symptoms, and by the time you do see them, untreated hypertension has caused damage to the heart, the kidneys, the arteries themselves, perhaps even your eyes and brain. The American Heart Association estimates that this condition affects one in three adults (71 million people) in the U.S.

When your doctor (or more likely the nurse) takes a blood pressure reading they get a picture of the pressure in the arteries at two different points – systolic (top number) for when the heart is pumping blood, diastolic (bottom number) for when the heart is at rest, getting blood from other parts of the body. A normal blood pressure reading is considered anything less than 120/80, with numbers over this increasing your risks of complications.

In this most recent study, the team randomly assigned 43 healthy, normal weight adult volunteers to either gain almost 9 pounds or stay at their current weight.

The researchers measured endothelial function in the brachial artery in the arm, looking for the ability of the artery to dilate. Measurements were taken at the start of the study, after eight weeks of weight gain, and again after 16 weeks of weight loss for those who had gained weight. Weight gainers demonstrated a decrease in the ability of the artery to dilate, though when they lost the added weight, the ability went right back to normal.

Proven: Belly Fat Damages Blood Vessels & Ups Disease Risk… Continued…

The research shows that even the modest amount of weight we might gain after a vacation or over the holidays, has an impact on the body and potentially harmful affects on the blood vessels. Losing the weight gets things back to normal, if you manage to drop the pounds.

Lead researcher for this study, Dr. Virend K. Somers, a medical professor at the Mayo Clinic School of Medicine, believes that when people put on weight in the belly area, they have more trouble with endothelia function, which is a well known marker of the health of the blood vessels in the body. Fat in the belly area is especially troublesome, a belief that is increasingly supported by more and more experts.

The good news is that excess belly fat can respond to diet and exercise. Research has learned that eating a very specific kind of fat is an entirely natural way to fight both types of belly fat, subcutaneous (what you can see) and visceral (what you can’t). Add a few lifestyle changes and some targeted exercises and you can be on the way to getting your belly back down to size.

When our bodies have a lot of good microbes living in the digestive tract we’re able to digest and process what we eat without a problem.

Different types of food encourage different species to thrive, supporting natural diversity. This diversity allows people to adapt to different diets more easily.

The team compared fecal samples from 15 healthy children of the West African village Nanoro, with those of an equal number of subjects living in the city of Florence.

This particular African village was selected because of its isolation and the fact that the diet is very much like that of the Neolithic age – high in fiber, cereals, non animal protein and plants; the European children eat a more Western diet – high in animal protein, sugar and fat, but low in fiber.

All the study subjects were between 1 and 6 years old, and had taken no antibiotics or probiotics for the preceding six months. The information on diet came from parents. Not surprisingly the Italian subjects consumed more calories per day, 1512 vs. 996 among two to six year olds.

The study authors provided material that supports the idea that human’s digestive organisms changed quite a bit once agriculture took hold and the society was no longer nomadic… a scant 10,000 years ago.

Once the food supply changed, the number and types of bacteria changed too, perhaps bringing more diseases. Once antibiotics, vaccines and better hygiene took hold, some scientists believe that more changes in the organisms took place – coincidentally at the same time medicine was seeing an increased number of allergic and autoimmune diseases.

Researchers wonder if the bacteria that populate the small Western stomachs might predispose these subjects to obesity or allergies later in life. DNA analysis found that Italian children had more bacteria linked with obesity with fewer fatty acids that can cut down on inflammation. The populations of bacteria were less diverse in the Western diet eating subjects.

African children had more good bacteria, and even some unique strains that weren’t found in the other subjects. The work clearly verified the idea that there is a difference in colonization of digestive organisms associated with a low fat, low sugar, low prepared food diet.

The study raises the issue that diet might have just as much impact on the makeup of digestive organisms as do sanitation, climate and geography.

Western Diet Responsible for Excess Bad Bacteria… Continued…
This isn’t the first work to find that the Western diet might influence digestive organisms; an earlier work found that the mix of bacteria in a baby’s system might be able to predict whether that child will be overweight or obese later in life. Another study found that prescribing antibiotics to infants increases the chances the child might develop asthma.

The thing is, all of us eat too much cheap, convenient food according to Marianne Grant, registered dietitian and educator at Texas A&M Health Science Center Costal Bend Health Education Center. She contends that our bodies have not changed all that much since those hunter/gatherer days, and we should be eating more like our ancestors. Way more fruits and veggies and a lot of physical activity.

The work appears in the August 2-6, 2010 issue of the Proceedings of the National Academy of Sciences. The team hopes that the research might lead to new probiotics that help improve the ratio of good and bad stomach bacteria of those eating a Western diet. It also suggests, that minus the termites, this may be a way to feed young children, a diet more heavy in fiber but with the same amount of calories.

1. Thyroid Problems

The thyroid gland produces hormones that regulate the way your body uses energy. If this organ is underactive (hypothyroidism) your metabolism is disrupted which has many effects on the body. More common in women, the condition is usually diagnosed in the 40s and 50s. There are estimates that a full 10% of adults have hypothyroidism.

Besides that inability lose weight (or even gaining some) you might notice fatigue, hair loss, dry skin, muscle weakness and joint pain, heavy periods, increased sensitivity to cold, perhaps even depression. You can have a low-grade hypothyroidism and just feel “off” without any obvious sign of illness.

Ask your primary care physician for a TSH (thyroid-stimulating hormone) screening. While traditional levels are between .45 and 4.5, if you’re above 2.0 you probably will struggle to lose weight according to Dr. Jamie Kane, M.D., medical director of Park Avenue Medical Weight and Wellness in New York. Ask your doctor to look at T-3 and T-4 levels too. Some patients do well with a low dose thyroid hormone (Synthroid).

2. Hormone Imbalance

As many as 1 in ten women of childbearing age are believed to have polycystic ovary syndrome (PCOS). PCOS is known to cause ovulation problems and infertility, while also being linked to insulin resistance.

This is a possible explanation for your lack of weight loss success if you also have irregular periods, extra face and body hair, acne, some male pattern balding as well as the expected trouble getting pregnant. Not everyone with PCOS has weight issues.

Your gynecologist can test your levels of sex hormones, look at your blood sugar and insulin levels or order an ultrasound to look for cysts on your ovaries. Treatment involves lifestyle changes (eating healthy, exercising regularly) and watching your intake of refined carbs and added sugars. Your doctor might prescribe a medication known as Metformin that can treat insulin resistance and help you get pregnant.

3. Food Intolerances

Anyone with a food allergy knows what food they must avoid, but few of us are aware of the food intolerances that affect an estimated one I in ten people. An intolerance can be caused by a lack of a certain digestive enzyme (lactose intolerance, for example) or sensitivity to food additives (sulfites, for example). These intolerances (most commonly dairy, gluten, eggs, soy, corn and nuts) tend to show up over time and can bring on bloating and water weight gain, along with other symptoms.

If you often have bloating, gas, diarrhea and constipation as well as symptoms that aren’t related to digestion such as mild asthma, eczema, headaches, muscle and joint pain or fatigue, you need to talk with your doctor, and perhaps get a referral to a gastroenterologist. An elimination diet can start you on your way to figuring out what foods you can eat. Start by removing gluten and dairy and move on to the others. You can then systematically re-introduce foods and watch for your reactions.

You may need to say good-bye to a favorite food you can’t tolerate forever, but in milder cases you can first try using a daily probiotic supplement that brings back the good bacteria (yes there are good bacteria) to your digestive tract. Look for one with at least 10 billion live bacteria per capsule.

4 Unexpected Reasons Women Can’t Lose Weight… Continued…

4. Medication

While many prescription medications do you a world of good, there are some unwelcome side effects, weight gain often being one of these. Estimates have as many as 50 commonly used drugs that have weight gain as a side effect. Antidepressants, antipsychotics, anti-seizure medications, diabetes drugs, high blood pressure pills, steroids and birth control pills can all be at fault.

If you notice you’ve gained weight within a few weeks of starting a new medication, keep and eye on your progress, stick to your diet and fitness goals and discuss this with your doctor if you aren’t better by the first month. Often there’s an alternative medication that can be prescribed.

Never just stop taking a medication just because it may be one of the reasons for not losing weight. Talk with your doctor first. Treating the condition you’re taking the drug for is your main concern. Side effects, while unpleasant, are still better than the condition the drug is managing for you.

Your teeth are strong and pretty resilient overall, but if you have any with root canals or fillings that tooth is typically weaker. Bite down on something hard (ice, hard candy, olives, fruits that have pits or unpopped popcorn) and you’re more likely to suffer a crack or fracture in such a tooth, and an emergency trip to your dentist to boot.

When it comes to a great looking smile, one of the best (not the easiest mind you) thing you can do is to limit snacking. Beyond adding calories to your diet, snacking interrupts the flow of saliva meant to cleanse the mouth and teeth to remove cavity-producing substances. Constant snacking continually exposes your teeth to substances that erode enamel, which is why experts suggest you limit eating to three meals a day. If you do snack, choose a food that’s healthier, as these are less likely to cause tooth decay.

To ensure your smile always looks its best, here are seven things to add to your diet…

1. Water is the most natural, calorie free thirst quencher around, and helps to wash acid producing foods from the teeth and mouth.

2. Sugar free drinks are ideal if you like something with a bit more taste. These also serve to wash the acid producing food from the mouth.

3. Sugar free gum increases the flow of saliva, this helps to neutralize acids in the mouth and thus protect the enamel of the teeth. This is a great choice when you’re craving something sweet, but are watching your calorie intake.

4. Citrus fruit though acidic also increases the flow of saliva. Oranges, grapefruits and other such fruits offer protection to enamel because they contain a lot of water that washes away food and acids.

5. Cheese and milk not only encourage saliva production, the proteins in these foods also act as a buffer against acids so the enamel of the tooth is protected from erosion. There are studies that suggest these foods might possibly strengthen the protective minerals found in the surface of your teeth.

6. Fish and flax are thought to reduce inflammation and offer protection against gum disease. Omega-3 fatty acids are the most potent anti-inflammatory nutrients, and people who eat a lot of them are more resistant to both inflammation and infection, perhaps gum disease as well.

7. Cocoa has substances that keep inflammation in check and might also help protect teeth against erosion and decay. Dark chocolate is lower in sugar than the milk chocolate variety. And chocolate milk, which does have some sugar, does not appear to up the risk of cavities.

Now that you’ve seen what to add, here are some things to avoid…

Continues below…

Get A Bright, Healthy Smile With These Foods… Continued…

1. Sugary drinks: When the bacteria in the mouth break down simple sugars they produce acids that can erode enamel and create pits where cavities form. Because we sip them, these drinks raise acid levels over a long period of time. Carbonated drinks are especially bad, as the carbonation ups acidity. Some research has singled out sports drinks as the worst offenders.

2. Candy and sweetened snacks: No surprise here since most of these are loaded with sugar that increases acid levels in the mouth. Sticky and gummy candies are the most destructive choice of all because they adhere to the tooth surface, making it hard for saliva to clean the teeth.

3. Sugary breakfast foods: These have a mix of sugar and starch, more likely to get stuck in the plaque between teeth. Ready to eat breakfast cereal, pastries and many processed (though highly convenient) breakfast foods are best avoided if you want to maintain a healthy smile.

4. Some starches: Breads, pasta, rice and potatoes raise the destructive acid levels in the mouth. The more refined (or cooked) a starch is, the more likely it will raise acid levels. Raw starches don’t endanger tooth enamel.

5. Coffee, tea and red wine: Beyond the fact that these beverage tend to stain the tooth surface, these drinks are typically sipped, allowing the acid levels in the mouth to remain high over a much longer period of time.

So, by following these natural teeth whitening tips you can have a bright and healthy smile with minimum intervention and cost.

The work involved 8,745 postmenopausal women (age 65 to 79) who had participated in the Women’s Health Initiative hormone trials and had no sign of cognitive problems. The participants received an examination of brain function that was designed to evaluate thinking and memory, answered health and lifestyle questions and were measured for weight, height, body circumference and blood pressure.

What the team found was that for every one-point increase in a woman’s BMI, her memory score dropped by a point on a test known as the Modified Mini-Mental Status Examination.

Obesity does indeed appear to be linked to worse cognitive function, with the effect more pronounced if the woman was pear shaped.

According to Diana R. Kerwin, an assistant professor of medicine at Northwestern University and lead researcher on the study, the message needs to be delivered to women that a high BMI is not good for your mind and memory. She speculates that pear shaped women experience more loss of memory because of the type of fat that gets deposited about the hips vs. the type found at the waist.

Earlier studies have shown that different types of fat (hips vs. waist) release different cytokines. Cytokines are hormones that can affect insulin resistance, cholesterol levels and blood pressure. They are also known to bring on inflammation and this may be what impacts cognition.

Memory Loss Linked To Extra Weight At The Hips… Continued…

Carrying weight around the hips might also contribute to the formation of plaques linked to Alzheimer’s disease, or cause restricted blood flow to the brain. Either way, experts warn that being obese (or overweight) is not good for our bodies, or our brains.

The researchers don’t know if their findings also apply to men, but they note that Alzheimer’s disease is 1.5 times more likely in a woman than a man. The body of research findings available now favors a most simple explanation for this – women live longer than men, and in the case of Alzheimer’s disease, time is important. Women also are more likely to have health conditions that up their risk, being obese, diabetic or having high cholesterol. Experts are also coming to recognize that Alzheimer’s affects men and women differently, with the typical Alzheimer’s caregiver being a 46-year-old woman, married and working outside the home.

Understand that whether you are pear shaped, or apple (larger waist compared to hips), you have this shape for life, even if your weight changes. So while you might not be able to change where your the fact you carry extra hip fat, you can take steps to be carrying less of it. Eating a well-balanced, nutritious diet is showing itself to be quite important, as is being active physically and socially while enjoying mentally stimulating activities.

Instead experts recommend that adults try to eat fish at least two times a week, with fattier fish like salmon, mackerel and trout as top picks.

Of the original 35,016 subjects in the research, 880 women were diagnosed with breast cancer by the end of the six-year study period. Among those who did get breast cancer only 5% reported regularly using fish oil at the start of the study. For those who remained free of cancer, 8% had been using fish oil at the beginning.

Even after considering factors like age, weight, self reported diet and exercise patterns, and family history of the disease; fish oil supplementation appeared to bring lower risk.

Clinical trials, the “gold standard” in terms of research, will tell us more, and senior researcher Dr. Emily White of the Fred Hutchinson Cancer Research Center in Seattle while aware of the limitations of her work, points to the upcoming clinical trial as a way to find out more. Conducted by Harvard University, it will randomly assign participants to take fish oil or vitamin supplements, or a placebo in an effort to understand if either has an impact on the risk of cancer, heart disease and stroke in an older population.

White contends it is biologically possible for fish oil to affect breast cancer. Fish oil does have anti-inflammatory effects and chronic inflammation in the body is thought to have a role in cancer growth and spread.

Even so, whether fish or fish oil has an impact on cancer risk remains unclear, the team makes note of two earlier studies that examined a woman’s omega-3 intake from food and risk of breast cancer with neither finding any link.

Continues below…

Do Fish Oil Supplements Lower Risk Of Breast Cancer..? Continued…

White’s team also noticed that in a subgroup of the subjects with a history of heart disease, using fish oil was tied to an increased breast cancer risk versus non-use. This is surprising, and may be due in part to the small number of subjects… representing a chance finding instead of an effect of fish oil. More work is needed here too.

Fish oil is a natural source of healthy fatty acids (omega-3s for example) and has proven itself in clinical trials to lower triglycerides, high blood pressure and the risk of heart attack in those with heart disease. What we need is more evidence… so far many pieces of the puzzle are uncovered, but have yet to come together to give experts a full picture.

If you’re interested in preventing breast cancer, there are things you can be doing to help yourself. Get screened regularly. Live a healthy lifestyle (or as healthy as is possible for you) by eating well, exercising regularly and getting the rest your body needs. Don’t smoke or drink alcohol to excess, and be aware of the chemicals that might be in your environment. When it comes to breast cancer prevention, the best defense is a smart offense.

Experts tell us that the gap between getting just enough sleep and sleeping too little is profound, suggesting that all of us pay more attention to the role sleep plays in our lives.

If you’re one of the many busy souls getting less than the recommended and research supported 7 to 8 hours of sleep a night, you won’t be able to deprive yourself like this over the long term.

But how much sleep is enough? Experts say there is no “magic number”, different ages need different amounts, and even then the right amount is highly individual. Research has even confirmed that sleep needs change across populations, so what’s right for you may be too much or too little for another.

In the end, you need to make getting enough sleep a priority, just as you do any other healthy lifestyle choice. In return, you’ll reap some pretty impressive benefits.

1. Better overall health: countless studies have found links between insufficient sleep and heart disease, heart attacks, diabetes and obesity. One study found disrupted sleep had an effect after only four days on blood glucose levels in a third of 10 healthy subjects, putting them in the pre-diabetic range.

2. Better sex life: a poll by the National Sleep Foundation has up to 26% of respondents reporting their sex lives suffer because they’re just too tired. For men, impaired sleep can also bring lower testosterone levels.

3. Less pain: any type of pain, chronic or acute, gets better if you get enough sleep; though being in pain makes sleeping a challenge to be sure. There’s a lot of research showing a link between sleep loss and a lower pain threshold; this may be why many doctors now prescribe sleep medication to patients as it can offer better pain management than some painkillers.

4. Less chance of injury: sleep deprivation has been linked with many terrible disasters, not to mention the fact that the Institute of Medicine estimates one of five car accidents in the U.S. are caused by drowsy driving. Being sleep deprived doesn’t just make you a danger behind the wheel, it also makes you more likely to trip, fall off a ladder, cut yourself… be the victim of a nasty household accident that could have been avoided.

5. Better mood: we all know that being tired makes you cranky, but lack of sleep can also effect your ability to regulate your emotions – so you’re more likely to snap, or burst into tears, perhaps start laughing uncontrollably. Over the long term the picture is less clear, but insomnia is linked to depression, anxiety and an increased risk of suicide. No one can say if the lack of sleep is a symptom of depression/anxiety or part of the cause.

6. Better weight control: sleep loss appears to go along with an increased risk of weight gain, partly because if you’re chronically overtired, you won’t have the energy to go for a jog or cook a healthy meal after work. What’s more, the hormone leptin, which plays a part in making you feel full, drops if you don’t get enough sleep, making you just plain hungrier (not to mention craving high fat, high calorie foods) than those who are getting enough sleep.

9 Great Reasons To Get More Sleep… Continued…

7. Clearer thinking: sleep loss does affect how you think, impairing your cognition, your attention and your decision making abilities. Research has shown that a subject who is sleep deprived is substantially worse at solving logic or math problems than when they’re well rested. Careless mistakes are also far more likely.

8. Better memory: experts know that while we sleep our brain processes and consolidates our memories from the day. If you aren’t getting enough sleep, those memories may not be stored correctly and may well be lost.

9. Stronger immunity: a recent study tracked over 150 subjects, monitoring their sleep habits for two weeks, then exposing them to a cold virus. Those who got 7 hours or less sleep a night were nearly three times more likely to get sick as those who got that magic eight hours sleep a night.

If you or someone you love is having trouble with sleep… being sleepy during the day or when you should be awake and alert, snoring, dealing with leg cramps or tingling, or with gasping or difficulty breathing during sleep, long term insomnia or anything that’s preventing you from getting the rest you need, it’s time to visit your doctor. There are lots of treatments that can help you get enough sleep that’s so important to good health.

Earlier research findings have been murky where coffee and cancer risk are concerned, though sugared sodas have been reliably linked to obesity and other health problems that are thought to increase the risk of colon cancer.

In this review, Dr. Xuehong Zhang and a team out of the Harvard School of Public Health evaluated 13 studies including more than 730,000 subjects from all over the world. The studies lasted from as few as 6 to as long as 20 years. Of the subjects, more than 5,600 were diagnosed with colon cancer.

Colon cancer rates vary widely between countries, and experts suspect that lifestyle factors may well play an important role

The team found that drinking more than 6, eight-ounce cups of coffee a day did not increase the risk of colon cancer. This supports earlier research into coffee drinking and cancer.

Nor did drinking more than 18 ounces a day of sugar filled sodas, though these beverages have been linked to increases in risk factors for colon cancer (such as being obese and having diabetes), but there’s been little direct research on the association.

The researchers note that the number of heavy soda drinkers in their work was small, only 2% of the total, and this may well have impacted the results.

Surprisingly, there was a small but respectable boost (28%) in colon cancer risk for heavy tea drinkers (more than 4, eight-ounce cups of non-herbal tea/day). This too, the researchers caution, requires further study as there were not large numbers of subjects who drank that much tea.

The relationship is unclear at the moment according to Zhang as tea is known to have antioxidants that are thought to help prevent cancer, but also polyamines that have been found to promote cancer.

Continues below…

Certain Drinks Not Linked To Colon Cancer… Continued…

The team also noted that their findings on cancer risk were not affected all that much by other factors such as smoking status, alcohol consumption and gender of the subjects.

In a commentary that appeared with the review, experts from the Arizona Cancer Center point out that sugar sodas are the drinks of choice for children in many countries, unlike either coffee or tea.

Sweetened beverage intake is generally lower among older people. These differences in exposure suggest that the intake of sweetened drinks may call for earlier intervention by health care professionals in order to ward off later disease.

According to the American Cancer Society, colon cancer is one of the leading causes of cancer related death in the U.S., though the rate has been going down (thanks to better screening and treatments) over the last 15 years. This is why, as uncomfortable as they might make you, regular screening tests are one of the best ways to reduce your colon cancer risk. When caught early, patients can expect a complete cure.

No one wants to admit they’re carrying more pounds than is good for them, yet if the steadily rising obesity rates are any clue, we’re all only getting heavier. And this added weight is upping the risk of not only cardiovascular disease, but many other acquired diseases.

Experts warn that obesity isn’t just a problem on its own, those extra pounds are exacerbating other risks to our hearts as well. Carrying more weight than you should plays a part in almost all the coronary risk factors – boosting levels of bad cholesterol, raising blood pressure and increasing the chances of developing diabetes. All three are considered risk factors for heart disease.

All three respond readily to sustained weight loss.

A study just presented at an annual meeting of American Heart Association found that blood pressure and blood sugar levels keep going up in adults, driven mainly by increases in obesity. This overwhelms improving heart health trends like the drops in bad cholesterol and lower rates of smoking. And while we can replace the machines in our lives with new ones, our body, a truly fantastic machine, can’t be traded for new, its ours for life.

With childhood obesity rates also on the rise, the experts don’t hold out much hope for improvement in the coming years. Today, according to the Centers for Disease Control and Prevention, one out of every three kids and teens in the U.S. is obese. These children are far more likely to develop dangerous heart disease as they get older.

The answer isn’t one we want to hear, but if you’re concerned about heart disease, a hard look at your weight (or BMI number) is in order. Once you recover, you’ll want to start making some changes including …

- Eating more fruits and veggies, adding a serving a day and building from there.

- Choosing lean meats, try to eat fish more often.

- Choosing whole grain breads/pastas or brown rice over white.

- Eliminating sugary drinks and fruit juices, go for the diet version or water instead.

Experts Warn: More Weight, More Heart Risk Continued…

What you eat is only part of the picture… to lose weight you’ve got to be more active.

When it comes to exercise, start slowly and build over time, especially if you’ve been inactive for a long while. Before you begin, talk with your doctor to be sure being active is safe for you. Once you get the okay, start by walking (or doing another enjoyable activity) three times a week and build from there.

Keep in mind that every pound equals almost 3,500 calories, so to lose a pound each week you’ll need to burn 500 more calories a day than you take in.

Remember successful weight loss takes time… after all, that weight didn’t appear overnight, losing it won’t happen that fast either. Experts recommend you start by setting a weight loss goal of 10 pounds in 6 months, and build from there. Losing just 10% of your body weight can have impressive benefits on your heart disease risks, and get you on the track to losing even more.

One work, appearing in the July 12, 2010 issue of the Archives of Internal Medicine suggests that low levels of vitamin D in the blood could increase the risk of cognitive decline.

The work included 858 adults over 65, and those who had the lowest blood levels of the vitamin, under 25 nanomoles per liter, were 60% more likely to have signs of general cognitive decline over the course of the 6 year study. They were also 31% more likely to demonstrate declines in their ability to plan, organize and prioritize than those in the study who had sufficient levels of vitamin D in the blood.

You’ve heard vitamin D called the “sunshine vitamin” because we produce it when we’re out in the sun without sunscreen. It’s naturally a part of very few foods (salmon, tuna, mackerel, fish liver oils, beef liver, cheese, egg yolks, mushrooms), and is added to many others like milk, cereals, orange juice, yogurt and margarine.

There’s been plenty of research in recent years to link vitamin D deficiency to problems like heart disease, osteoporosis, diabetes, schizophrenia, some autoimmune disorders and even certain cancers.

Today from 40-100% of older adults in both the U.S. and Europe could be deficient in vitamin D according to information cited by the researchers. The study has raised the idea that vitamin D supplements might have some potential for the prevention of dementia, though clinical trails are needed to define the optimal intake.

Experts worry about low levels of vitamin D in the frail or elderly, in those with dark skin or anyone who totally avoids the sun. All adults, according to Michael Holick, MD, PhD, a professor at the Boston University School of Medicine and director of the school’s Vitamin D, Skin, and Bone Research Lab, should be taking in 2,000 international units (IUs) of vitamin D a day, significantly higher than the current dietary recommendations. The Institute of Medicine is considering new recommendations for intake as you read this.

Holick suggests that the time to start supplementing is before you see signs of dementia or another condition. Vitamin D is better at preventing that treating disease.

The other work, appearing in the July 12, 2010 issue of the Archives of Neurology, finds that eating foods rich in vitamin E could help bring lower risk for dementia and Alzheimer’s disease. This study included 5,395 dementia free subjects over 55, finding that those who got the highest amounts of vitamin E (18.5 milligrams/day) were 25% less likely to develop dementia than those who got the least vitamin E in their diet (about 9 milligrams/day).

Study leader Elizabeth R. Devore ScD of Erasmus Medical Center in the Netherlands and her colleagues followed the participants for 9.6 years. During that time there were 465 cases of dementia; 365 of those were considered Alzheimer’s disease.

The large, observational study was intended to evaluate more than vitamin E; vitamin C, beta-carotene and flavonoids consumed were also investigated, though only the vitamin E was related to dementia risk. The participants in this study reported that they got their vitamin E from sources like margarine, sunflower oil, butter, cooking fat, soybean oil and mayo.

Latest Research Links Dementia With Vitamin Deficiency… Continued…

Vitamin E is a natural part of whole grains, wheat germ, leafy green veggies, sardines, egg yolks, nuts and seeds, and a source of antioxidants known to protect the body from the damage caused by free radicals. The brain, being a site of high metabolic activity is especially vulnerable to oxidative damage, and in need of the protection that can come from this nutrient.

As encouraging as these results appear, experts caution that more work is needed before any recommendations can be made in terms of best vitamin intake and dementia risk. If your levels of either nutrient are particularly low, you may need to supplement, but otherwise it’s too early to suggest that this will do you good. Whole foods sources of nutrients are, after all, always preferable to supplements.
