Almost half of UK women could be suffering from a lack of vitamin A due to a previously undiscovered genetic variation, scientists at Newcastle University have found. The team, led by Dr Georg Lietz, has shown that almost 50 per cent of women have a genetic variation which reduces their ability to produce sufficient amounts of vitamin A from beta-carotene. Vitamin A – also known as retinol – plays a vital role in strengthening our immune system, protecting us against common infections such as flu and winter vomiting. Vitamin A also helps to maintain healthy skin and mucus linings such...

Effects of vitamin D deficiency amplified by shortage of estrogenResearchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and...

Official guidance on how much we can eat each day has been underestimated for the last two decades, scientists have revealed. The daily intake of calories - currently 2,000 for woman and 2,500 for men - could be increased by up to 16 per cent, the equivalent of cheeseburger or two packets of crisps. An average adult could happily squeeze in an extra 400 calories a day and not pile on the pounds, Britain's leading nutritionists have admitted.

> Magnesium is a must. The diets of all Americans are likely to be deficient. Even a mild deficiency causes sensitiveness to noise, nervousness, irritability, mental depression, confusion, twitching, trembling, apprehension, insomnia, muscle weakness and cramps in the toes, feet, legs, or fingers. Folic acid deficiency can lead to neural tube closure defects (NTDs) and anemia. Zinc deficiency affects immune function, contributing to as many as 800,000 child deaths per year. Iodine deficiency is the leading preventable cause of brain damage and it can significantly lower the IQ of whole populations. >

Supplements of the sunshine vitamin may improve insulin resistance and sensitivity, both of which are risk factors for diabetes, says a new study from New Zealand. Insulin resistance, whereby insufficient insulin is released to produce a normal glucose response from fat, muscle and liver cells, was significantly lower in women following high-dose vitamin D supplementation, according to results of a randomised, controlled, double-blind trial published in the British Journal of Nutrition. The optimal effects were observed when blood vitamin D levels were in the range 80 to 119 nanomoles per litre, said the researchers, “providing further evidence for an increase...

NEW YORK (Reuters Health) – Eating lots of whole grains could ward off high blood pressure, according to a study in the American Journal of Clinical Nutrition. In the study, men with the highest whole-grain consumption were 19 percent less likely to develop high blood pressure than men who ate the least amount of whole grains. While refining grains removes their outer coating, whole grains retain their bran and germ, so they are richer in many nutrients, Dr. Alan J. Flint of the Harvard School of Public Health in Boston and his colleagues note in their report. The most recent...

A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin. "It's likely that more than one-third of older adults...

Let's say you're preparing dinner and you realize with dismay that you don't have any certified organic Tuscan kale. What to do? Here's how Michelle Obama handled this very predicament Thursday afternoon: The Secret Service and the D.C. police brought in three dozen vehicles and shut down H Street, Vermont Avenue, two lanes of I Street and an entrance to the McPherson Square Metro station. They swept the area, in front of the Department of Veterans Affairs, with bomb-sniffing dogs and installed magnetometers in the middle of the street, put up barricades to keep pedestrians out, and took positions with...

Miami, FL (AHN) - Babies fed formula supplemented with an essential fatty acid found in breast milk have higher cognitive skills than babies fed formula alone, according to a new study. Previous research already showed the cognitive benefits of breastfeeding, but University of Texas researchers and scientists with the Retina Foundation of the Southwest said they have discovered that the fatty acid docosahexaenoic acid, or DHA, could be the reason. The scientists studied 229 infants receiving either formula or a combination of formula and DHA. The babies were given the different formulas either shortly after they were born, after six...

Despite the efforts restaurant chains from fast food to fine dining have made to add more-healthful items to the menu, consumers still aren’t buying. In a poll on chainleader.com, 82 percent of respondents say their better-for-you items are selling “lousy.” Recent research shows that customers cite economic factors as a reason for not purchasing healthful food—or as an excuse. Too Great a Cost Chicago-based foodservice consulting firm Technomic says its research shows the recession is hindering consumers’ healthy-eating behavior. Although more than half of consumers say they are more concerned about their eating habits than they were a year ago,...

Reliapundit alerts us to breaking news: Gertrude Baines, who lived to be the world's oldest person on a steady diet of crispy bacon, fried chicken and ice cream, died Friday at a nursing home. She was 115. Baines, who remarked last year that she enjoyed life so much she wouldn't mind living another 100 years, died in her sleep, said Emma Camanag, administrator at Western Convalescent Hospital. The centenarian likely suffered a heart attack, said her longtime physician, Dr. Charles Witt. An autopsy was scheduled to determine the cause of death. ...Staff at Baines' nursing home described her as a...

Scientists have discovered that a component of the superfood can protect arteries from “furring” which can block blood flow and lead to angina, heart attack and stroke. Arteries don’t clog at the same rate and researchers know that a protein is inactive in parts which are more vulnerable to disease. New tests suggest that a chemical found in vegetables such as broccoli, cabbage and cauliflower can boost a natural defence mechanism to protect against the damage. Tests in mice have shown that the chemical, known as Sulforaphane, found naturally in the vegetables can stimulate the protein to offer this protective...

New research in the FASEB Journal identifies the 'Goldilocks dose' of DHA that is 'just right' for preventing oxidative stress in menA team of French scientists have found the dose of DHA (docosahexaenoic acid) that is "just right" for preventing cardiovascular disease in healthy men. In a research report appearing in the September 2009 print issue of The FASEB Journal (http://www.fasebj.org), the scientists show that a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes. This study is the first to identify...

The tomato pill: Daily dose is as good for the heart as Mediterranean food By TAMARA COHEN 31st August 2009 British scientists have developed a groundbreaking pill which provides all the health benefits of a Mediterranean diet. One capsule of Ateronon taken daily can break down fatty deposits in the arteries and help prevent heart disease and strokes, potentially saving millions of lives. The supplement, which costs £35 for a month's supply, contains lycopene, a chemical found in the skin of ripe tomatoes. Each pill provides the equivalent of eating three kilos of ripe tomatoes. Studies have shown eating an...

"I'm president of the United States, and I'm not going to eat any more broccoli!" proclaimed George H.W. Bush in a 1990 news conference. America's 41st president disdained broccoli so much that he banned the vegetable from the White House menu. Now 84, Bush may live to regret his broccoli bullying: New scientific evidence suggests that a chemical in broccoli may rejuvenate the immune system enough to ward off common diseases of aging. At the University of California- Los Angeles, Andre Nel and colleagues recently discovered that sulforaphane, a phytonutrient in broccoli, activates antioxidant pathways at the cellular level. Injected...

Since the best minds of the country have concluded that health care is a basic human right, it must also be presumed that this right automatically includes the most fundamental component of all human health - food. Leading nation's scientists have long been warning us that denying a person the nutrition from food impairs health in the most direct and injurious manner. Today the debate is over: the right to health and the right to food are pretty much one and the same - the inalienable human right to have your bodily functions regulated by the government for your own...

Researchers found the average 25-year-old consumes over 2,300 calories a day, exercises only three times a week and munches on 12 types of junk food a month. But the typical 50-year-old has only 1,990 calories each day, does at least four forms of exercise and treats themselves to just one piece of junk food each week. And while those in their mid-20s have three takeaways a month, the older generation have only one. The study, commissioned by global nutrition and direct selling company Herbalife, quizzed 4,000 Brits on their diet and lifestyle. Neil Spiers, Herbalife's Regional Vice President, said: "The...

Polysaccharides from black tea may blunt the spike in sugar levels after a meal more than similar compounds from green and oolong tea, and offer potential to manage diabetes, says a new study. The black tea polysaccharides also exhibited the greatest activity for scavenging free radicals, which are linked to development of diseases such as cancer and rheumatoid arthritis, according to new findings published in the Journal of Food Science. Interest in tea and its constituents has bloomed in recent years, with the greatest focus on the leaf’s polyphenol content. Green tea contains between 30 and 40 per cent of...

BOSTON — The high prevalence of vitamin D deficiency found in a cohort of healthy children in a sunny Southwestern climate has prompted a call by the study's investigators for generalized routine screening of vitamin D levels among all children. In a study designed to assess vitamin D levels in children living in a region with year-round sunshine and to compare vitamin D levels in children with vague musculoskeletal pain with those of children without pain, Dr. Elizabeth A. Szalay and her colleagues at the University of New Mexico Hospital in Albuquerque retrospectively studied the serum 25-hydroxyvitamin D (25[OH]D) levels...

COLUMBUS, Ohio – A study comparing how two common dietary oil supplements affect body composition suggests that both oils, by themselves, can lower body fat in obese postmenopausal women with Type 2 diabetes. The two oils compared were safflower oil, a common cooking oil, and conjugated linoleic acid (CLA), a compound naturally found in some meat and dairy products that has been associated with weight loss in previous studies. Both are composed primarily of polyunsaturated fatty acids, which are considered “good fats” that, when consumed in proper quantities, are associated with a variety of health benefits. In the study, 16...

BOSTON (June 18, 2009) - Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University. The researchers calculated intakes of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) from dietary questionnaires administered to 2,924 men and women, aged 55 to 80 years, participating in an eight-year supplement trial, the...

Based on the long-time claim by General Mills that its Cheerios cereal can lower cholesterol by 4 percent in just six weeks — when part of a diet low in saturated fat and cholesterol, of course — the Food and Drug Administration has admonished the giant breakfast cereal producer and said those claims mean the little round “o’s” of oats are to be considered a drug. Simply by indicating the cereal is intended for use as a cholesterol-lowering product, it now falls under the FDA regulations regarding drugs, and because it’s a “new” drug by definition — never mind that...

Appearing in the June 5 issue of JBC For the past century, changes in the Western diet have altered the consumption of omega-6 fatty acids (w6, found in meat and vegetable oils) compared with omega-3 fatty acids (w3, found in flax and fish oil). Many studies seem to indicate this shift has brought about an increased risk of inflammation (associated with autoimmunity and allergy), and now using a controlled diet study with human volunteers, researchers may have teased out a biological basis for these reported changes. Anthropological evidence suggests that human ancestors maintained a 2:1 w6/w3 ratio for much of...

SAN DIEGO — The Institute of Medicine is reviewing its 1997 guidelines for vitamin D intake, and will likely recommend increased supplementation when new guidelines are published in 2010. There is a growing consensus that currently recommended intakes—200 IU per day for individuals under age 50 and 400 IU for those aged 50-70—are too low, said Connie Weaver, Ph.D., director of the department of food and nutrition, at Purdue University, West Lafayette, Ind. A recent analysis of data collected by the National Health and Nutrition Examination Survey (NHANES) during 1988-1994 and 2001-2004 even suggests that an epidemic of vitamin D...

WASHINGTON – The increased use of ethanol could cost the government up to $900 million for food stamps and child nutrition programs, a congressional report says. Higher use of the corn-based fuel additive accounted for about 10 percent to 15 percent of the rise in food prices between April 2007 and April 2008 .. The CBO said other factors, such as skyrocketing energy costs, had an even greater impact than ethanol on food prices during that period. .. Ethanol's impact on future food prices is uncertain, the report says, because an increased supply of corn has the potential to eventually...

Major Study Finds an Effect, but Critics Say Meat Offers Important NutrientsDiets high in red meat and in processed meat shorten life span not just from cancer and heart disease but from Alzheimer's, stomach ulcers and an array of other conditions as well, a U.S. National Cancer Institute study has found. In fact, reducing meat consumption to the amount eaten by the bottom 20 percent seen in the study would save 11 percent of men's lives and 16 percent of women's, according to the study. "The consumption of red meat was associated with a modest increase in total mortality," said...

CHICAGO – The largest study of its kind finds that older Americans who eat large amounts of red meat and processed meats face a greater risk of death from heart disease and cancer. The federal study of more than half a million men and women bolsters prior evidence of the health risks of diets laden with red meat like hamburger and processed meats like hot dogs, bacon and cold cuts. Calling the increased risk modest, lead author Rashmi Sinha of the National Cancer Institute said the findings support the advice of several health groups to limit red and processed meat...

Sugar, the nutritional pariah that dentists and dietitians have long reviled, is enjoying a second act, dressed up as a natural, healthful ingredient. From the tomato sauce on a Pizza Hut pie called “The Natural,” to the just-released soda Pepsi Natural, some of the biggest players in the American food business have started, in the last few months, replacing high-fructose corn syrup with old-fashioned sugar. ConAgra uses only sugar or honey in its new Healthy Choice All Natural frozen entrees. Kraft Foods recently removed the corn sweetener from its salad dressings, and is working on its Lunchables line of portable...

Levels of the beneficial, cancer-fighting compound sulforaphane in broccoli are reduced by 90 percent when the vegetable is cooked, according to a study conducted by researchers from TNO Quality of Life in the Netherlands, and published in the Journal of Agricultural and Food Chemistry. "Consumption of raw broccoli resulted in faster absorption, higher bioavailability, and higher peak plasma amounts of sulforaphane, compared to cooked broccoli," the researchers wrote. Eight male participants were fed 200 grams of crushed raw or crushed cooked broccoli as part of a warm meal; researchers then measured the men's blood and urine levels of sulforaphane. Based...

Study Shows Vitamin C From Food or Supplements May Reduce the Risk of Gout Reviewed By Louise Chang, MD Boosting vitamin C intake may be a simple way to help prevent one of the most common forms of arthritis. A new study shows the vitamin better known for fighting colds may also prevent gout. Researchers found men who had the highest vitamin C intake from supplements and food were up to 45% less likely to develop the painful condition than those who had the lowest. Vitamin C is found naturally in citrus fruit, broccoli, and other fruits and vegetables; it...

WEDNESDAY, March 4 (HealthDay News) -- Many teens today, especially black teens, aren't getting enough of vitamin D, the so-called sunshine vitamin that is essential for cells to function, say researchers from Weill Cornell Medical College in New York City. Vitamin D deficiency has been linked to many chronic diseases, including heart disease, diabetes, immune system problems and inflammatory diseases. "There is evidence that the levels of vitamin D we have been using in the past may have been too low," said lead researcher Dr. Sandy Saintonge, a fellow in general preventive medicine at Weill Cornell. Vitamin D is measured...

Studying the anticancer benefits of dry beans, scientists have discovered that different market classes of beans help in reducing the risk of mammary cancer. For the study, researchers at Colorado State University studied the anticancer activity of six market classes of bean including; small red, great northern, navy, black, dark red and white kidney bean in the diet of laboratory animals. They also evaluated whether the level of antioxidants or seed coat pigments in the bean were related to mammary cancer. The researchers fed cooked dry bean powder from the six market classes and a control group without beans in...

Children who regularly eat cured meats like bacon and hot dogs may have a heightened risk of leukemia, while vegetables and soy products may help protect against cancer, a new study suggests. Researchers found that among 515 Taiwanese children and teenagers with and without acute leukemia, those who ate cured meats and fish more than once a week had a 74 percent higher risk of leukemia than those who rarely ate these foods. On the other hand, kids who often ate vegetables and soy products, like tofu, had about half the leukemia risk of their peers who shunned vegetables and...

Durham, NC - A Duke researcher says that despite the lack of a "gold-standard" clinical trial proving the benefits of a low-carb approach, he has seen enough in his own patients to know that, at least for some, a very low-carb approach can essentially reverse diabetes, without adversely affecting lipid profiles [1]. In his latest published research, Dr Eric C Westman (Duke University Medical Center, Durham, NC) and colleagues report that obese patients with type 2 diabetes randomized to a low-carbohydrate diet rather than a low-glycemic, reduced-calorie diet were more likely to experience improvements in glycemic control and, in some...

Doses of vitamin B1 (thiamine) can reverse early kidney disease in people with type 2 diabetes, research shows. The team from Warwick University tested the effect of vitamin B1, which is found in meat, yeast and grain, on 40 patients from Pakistan. The treatment stopped the loss of a key protein in the urine, the journal Diabetologia reports. Charity Diabetes UK called the results "very promising" - but said it was too early for any firm conclusions.

Targeting Obesity Alongside Hunger Obama Administration May Look to Tie Food Assistance to Improved Nutrition In many areas where lots of people receive aid, good, nutritious food can be scarce. The District's Ward 8 went nine years without a full-service grocer. By Jane Black Washington Post Staff Writer Wednesday, December 24, 2008; Page A02 The worsening economic crunch is causing the tab for food assistance programs to balloon, and with the rising costs has come an intensifying debate over whether -- and how -- the U.S. government can tackle simultaneously the paradoxically linked problems of hunger and obesity. The statistics...

NEW YORK (Reuters Health) – For people who have type 2 diabetes, a low-glycemic index diet is significantly better than a high-fiber diet for keeping blood glucose levels down, researchers report Glycemic index, or GI, refers to how rapidly a food causes blood sugar to rise. High-GI foods, like white bread and potatoes, tend to spur a quick surge in blood sugar, while low-GI foods, such as lentils, soybeans, yogurt and many high-fiber grains, produce a more gradual increase in blood sugar. The current study in this week's Journal of the American Medical Association involved 210 individuals with type 2...

RAWALPINDI, Pakistan - Travelers to Africa and Asia all have their favorite forms of foreign aid to "make a difference." One of mine is a miracle substance that is cheap and actually makes people smarter. Unfortunately, it has one appalling side effect. No, it doesn't make you sterile, but it is just about the least sexy substance in the world. Indeed, because it's so numbingly boring, few people pay attention to it or invest in it. (Or dare write about it!) It's iodized salt. Almost one-third of the world's people don't get enough iodine from food and water. The result...

A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health. The finding, published online Wednesday in the journal Cell, is from a group led by David Sinclair of the Harvard Medical School. It is part of a growing effort by biologists to understand the sirtuins and other powerful agents...

According to researchers in the U.S. the loss of potassium experienced from taking blood pressure drugs may explain higher risk of adult diabetes. The researchers from Johns Hopkins University School of Medicine say they have discovered that a drop in blood potassium levels caused by diuretics commonly prescribed for high blood pressure, could be the reason why people on those drugs are at risk for developing type 2 diabetes. It seems that while the drugs help to accelerate the loss of fluids they also deplete important chemicals, including potassium and those prescribed them are generally advised to eat bananas and...

Chicago, IL (AHN) - To battle the growing public perception that McDonald's offerings are not healthy, the fast food chain is tapping more mothers as its frontline warriors under the firm's Quality Correspondents program. McDonald's launched the program in 2007 and recently tapped five mothers in the Washington region to be part of the program. The five are among the thousands who responded to a TV ad seeking volunteers to help explain the nutritional value of McDonald meals to the public. "What to Eat" author Marion Nestle, a nutritionist at the New York University, said because of McDonald's size as...

[Free breakfasts], handed to students in bags as they stampede through the doors of the school in Long Island City, Queens, are meant to increase the number of children who eat what nutritionists consider the most important meal of the day. Since 2003, the city has offered free breakfast to all students, rich and poor; about 1 in 5 eat it. Among students from low-income families who qualify for a free or reduced-price lunch, 21 percent participate in the program, a level some educators have attributed to the stigma associated with showing up early for breakfast in the cafeteria.

The Dark Side of Linus Pauling's Legacy Stephen Barrett, M.D. Linus Pauling, Ph.D. (1901-1994), was the only person ever to win two unshared Nobel prizes. He received these awards for chemistry in 1954 and for peace in 1962. He contributed greatly to the development of chemical theories. His impact on the health marketplace, however, was anything but laudable. Pauling is largely responsible for the widespread misbelief that high doses of vitamin C are effective against colds and other illnesses. In 1968, he postulated that people's needs for vitamins and other nutrients vary markedly and that to maintain good health, many...

WASHINGTON — How fast you can throw a ball or run or swerve a steering wheel depends on how speedily brain cells fire off commands to muscles. Fast firing depends on good insulation for your brain’s wiring.Now research suggests that in middle age, even healthy people begin to lose some of that insulation in a motor-control part of the brain — at the same rate that their speed subtly slows.And while that may sound depressing, keep reading. The research points to yet another reason to stay physically and mentally active: An exercised brain may spot fraying insulation quicker and signal...

ScienceDaily (Oct. 19, 2008) — Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats. Although previous studies have shown that being leptin resistant can lead to rapid weight gain on a high-fat, high-calorie diet, this is the first study to show that leptin resistance can develop as a result of high fructose consumption. The study also showed for the first time that leptin resistance can develop silently, that is, with little indication that it is happening. The study...
