Vitamin E may do more harm than good

Vitamin-fortified foods and dietary health supplements can ease health worries. But what kinds of vitamins are right for you? And how much of them should you take, and how often?A research group from Tel Aviv University has done the most comprehensive and accurate study of clinical data on Vitamin E use and heart disease to date, and it warns that indiscriminate use of high-dose Vitamin E supplementation does more harm than good. Their results were recently reported in ATVB, a leading journal of cardiology, and discussed in the journal BioFactors."There were so many conflicting reports about Vitamin E and its effect on various diseases, particularly heart disease, that we wanted to set the record straight, says Prof. Dov Lichtenberg of TAU's Sackler School of Medicine."Our new study shows...

Factors Associated With Skin Aging

Smoking, being heavier, not using sunscreen and having had skin cancer appear to be associated with sun damage and aging of skin on the face, according to report based on a study of twins in the December issue of Archives of Dermatology, one of the JAMA/Archives journals.Long-term exposure to the sun causes physical and structural changes to the skin, resulting in photodamage, according to background information in the article. Unlike typical skin aging, which is characterized by the development of fine wrinkles and skin growths, photodamage includes characteristics such as coarsely wrinkled skin, spots of extra pigment or lost pigment and dilated blood vessels on the face. Sun damage also has been associated with the development of cancerous growths. Up to 40 percent of aging-related changes...

Bourbon Hurts More the Next Day

Bourbon Versus Vodka: Bourbon Hurts More the Next Day, Due to Byproducts of Fermenting ProcessMany alcoholic beverages contain byproducts of the materials used in the fermenting process. These byproducts are called "congeners," complex organic molecules with toxic effects including acetone, acetaldehyde, fusel oil, tannins, and furfural. Bourbon has 37 times the amount of congeners that vodka has. A new study has found that while drinking a lot of bourbon can cause a worse hangover than drinking a lot of vodka, impairment in people's next-day task performance is about the same for both beverages.Results will be published in the March 2010 issue of Alcoholism: Clinical & Experimental Research."While the toxic chemicals called congeners could be poisonous in large amounts, they occur in...

Moderate Fish Consumption May Lower heart Risk

Including fish in a balanced diet has long been associated with the prevention of heart disease, and scientists now believe that it can help preserve heart function in patients who have experienced heart failure. A new study in the Journal of Food Science reports that moderate fish consumption can help reduce the risk of left ventricular systolic dysfunction (LVSD) in post acute coronary syndrome (ACS) patients.Researchers from the University of Athens in Greece focused on demographical, nutritional, lifestyle, and medical factors combined with the risk of developing left ventricular dysfunction after nonfatal heart failure. The study included nearly one thousand patients who were hospitalized after ACS. At the study’s conclusion, researchers noted that consuming fish one to two times per...

Eat Fruits and Vegetable for Better Vision

Carotenoids, found in green leafy vegetables and colored fruits, have been found to increase visual performance and may prevent age-related eye diseases, according to a study in the Journal of Food Science, published by the Institute of Food Technologists. Authors from the University of Georgia compiled the results of multiple studies on the effects of the carotenoids lutein and zeaxanthin on visual performance. These carotenoids play an important role in human vision, including a positive impact on the retina.After reviewing the various studies, the authors concluded that macular pigments, such as lutein and zeaxanthin do have an effect on visual performance. Lutein and zeaxanthin can reduce disability and discomfort from glare, enhance contrast, and reduce photostress recovery times. They...

Don't Take Aspirin Or Advil Before Sports (I Do)

Athletes' superstitions and rituals can help them get psyched up for contests, but when these rituals involve non-steroidal anti-inflammatory drugs (NSAIDs), which many athletes gobble down before and during events, they could be causing more harm than good."These agents are treatments for the symptoms of an injury, not the injury itself," says Stuart Warden, whose research at Indiana University focuses on musculoskeletal health and sports medicine. "They may allow an athlete to exercise or train at a certain level, but pain occurs for a reason. It is basically the body's mechanism of saying, 'Hang on, you've got some sort of injury that should not be ignored.'"NSAIDs are recommended for use after an injury to reduce swelling or pain. Studies have found that many elite athletes, however, take...

Methionine could increase risk of Alzheimer’s

A diet rich in methionine, an amino acid typically found in red meats, fish, beans, eggs, garlic, lentils, onions, yogurt and seeds, can possibly increase the risk of developing Alzheimer’s disease, according to a study by Temple researchers.The researchers published their findings, titled “Diet-induced hyperhomocysteinemia increases Amyloid-β formation and deposition in a mouse model of Alzheimer’s disease,” in the journal Current Alzheimer Research.“When methionine reaches too high a level, our body tries to protect itself by transforming it into a particular amino acid called homocysteine,” said lead researcher Domenico Praticò, an associate professor of pharmacology in the School of Medicine. “The data from previous studies show — even in humans — when the level of homocysteine in the...

Omega-3 = better nervous-system function

The omega-3 essential fatty acids commonly found in fatty fish and algae help animals avoid sensory overload, according to research published by the American Psychological Association. The finding connects low omega-3s to the information-processing problems found in people with schizophrenia; bipolar, obsessive-compulsive, and attention-deficit hyperactivity disorders; Huntington's disease; and other afflictions of the nervous system.The study, reported in the journal Behavioral Neuroscience, provides more evidence that fish is brain food. The key finding was that two omega-3 fatty acids – docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) – appear to be most useful in the nervous system, maybe by maintaining nerve-cell membranes."It is an uphill battle now to reverse the message that...

Coffee, Tea = Reduced Risk of Diabetes

Drinking more coffee (regular or decaffeinated) or tea appears to lower the risk of developing type 2 diabetes, according to an analysis of previous studies reported in the December 14/28 issue of Archives of Internal Medicine, JAMA (1).By the year 2025, approximately 380 million individuals worldwide will be affected by type 2 diabetes (1).Despite considerable research attention, the role of specific dietary and lifestyle factors remains uncertain, although obesity and physical inactivity have consistently been reported to raise the risk of diabetes mellitus. A previously published meta-analysis suggested drinking more coffee may be linked with a reduced risk, but the amount of available information has more than doubled since.Rachel Huxley, D.Phil, of The George Institute for International...

Exercise improves survival from colorectal cancer

Men who have been treated for colorectal cancer can reduce their risk of dying from the disease by engaging in regular exercise, according to a new study by researchers at Dana-Farber Cancer Institute. The findings are published in the December 14 issue of the Archives of Internal Medicine."Previous research has shown regular physical activity reduces the risk of developing colon cancer," says the study's lead author, Jeffrey A. Meyerhardt, MD, MPH, of Dana-Farber. "This current study confirms two other studies from our group that shows physical activity by colorectal cancer survivors helps them live longer than those survivors who are not physically active."Meyerhardt and his team studied 668 men with colorectal cancer. More than 50 percent of the men exercised the equivalent of one hour...

Consumer Reports: BPA in Most Canned Foods

Consumer Reports’ latest tests of canned foods, including soups, juice, tuna, and green beans, have found that almost all of the 19 name-brand foods tested contain measurable levels of Bisphenol A (BPA). The new findings show that BPA can be found in a diverse assortment of canned foods including those labeled “organic,” and even in some foods packaged in “BPA-free” cans. Consumer Reports’ tests of a few comparable products in alternative types of packaging showed lower levels of BPA in most, but not all cases. The results are reported in the December 2009 issue.“The findings are noteworthy because they indicate the extent of potential exposure,” said Dr. Urvashi Rangan, Director of Technical Policy, at Consumers Union, nonprofit publisher of Consumer Reports. “Children eating multiple servings...

Pistachios May Reduce Lung Cancer Risk

A diet that incorporates a daily dose of pistachios may help reduce the risk of lung and other cancers, according to data presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference, held Dec. 6-9.“It is known that vitamin E provides a degree of protection against certain forms of cancer. Higher intakes of gamma-tocopherol, which is a form of vitamin E, may reduce the risk of lung cancer,” said Ladia M. Hernandez, M.S., R.D., L.D., senior research dietitian in the Department of Epidemiology at the University of Texas M. D. Anderson Cancer Center, and doctoral candidate at Texas Woman’s University - Houston Center.“Pistachios are a good source of gamma-tocopherol. Eating them increases intake of gamma-tocopherol so pistachios may help to decrease...

High-fat Low-carb Diets=Heart Risk

New scientific research has shown that low-carbohydrate high-fat diets, made popular by the likes of the Atkins diet, do not achieve more weight loss than low-fat high-carbohydrate diets. Worryingly, the research, lead by Dr Steven Hunter from the Royal Victoria Hospital, Belfast, also shows significantly increased risks of cardiovascular disease for people following low-carbohydrate high-fat diets.The research shows that the risks of low-carbohydrate high-fat diets far outweigh the potential benefits gained by overweight and obese people through weight loss, including improvements in blood pressure and risk factors for coronary heart disease.The research results, released hot on the heels of both National Obesity Week and World Diabetes Day, are particularly important for nearly a quarter...

Coffee = Reduced Risk of Advanced Prostate Cancer

Coffee Consumption Associated with Reduced Risk of Advanced Prostate CancerWhile it is too early for physicians to start advising their male patients to take up the habit of regular coffee drinking, data presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference revealed a strong inverse association between coffee consumption and the risk of lethal and advanced prostate cancers.“Coffee has effects on insulin and glucose metabolism as well as sex hormone levels, all of which play a role in prostate cancer. It was plausible that there may be an association between coffee and prostate cancer,” said Kathryn M. Wilson, Ph.D., a postdoctoral fellow at the Channing Laboratory, Harvard Medical School and the Harvard School of Public Health.In a prospective...

Fatty food can weaken the immune system

Fresh evidence that fatty food is bad for our health has come to light: mice fed a lard-based diet over a long period got worse at fighting bacteria in the blood, reveals a thesis from the Sahlgrenska Academy. The mice fed the lard-based diet derived 60 per cent of their total calories from fat. They were compared with mice fed a low-fat diet, where no more than ten per cent of their calories came from fat. As expected, the mice on the high-fat diet got fatter. A more surprising result was that their immune system was less active. The white blood cells got worse at dealing with bacteria in the blood, which could have contributed to many dying of sepsis. "Obesity is usually associated with inflammation that does not result from an infection, which simply means that the immune defences are activated...

Vitamin D levels = survival in lymphoma patients

A new study has found that the amount of vitamin D () in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology ) in New Orleans."These are some of the strongest findings yet between vitamin D and cancer outcome," says the study's lead investigator, Matthew Drake, M.D., Ph.D., an endocrinologist at Mayo Clinic in Rochester. "While these findings are very provocative, they are preliminary and need to be validated in other studies. However, they raise the issue of whether vitamin D supplementation might aid in treatment for this malignancy, and thus should stimulate much more research."The researchers' study of 374 newly diagnosed...

Methionine May Be Key To Longevity

Amino acids are the building blocks of life as they form the basis of proteins. Methionine is one of the most important amino acids at it is essential to the formation of all proteins. Whilst proteins are formed naturally in the body, we also consume proteins from many different food types, including meat and dairy products, soy-derived food such as tofu, and pulses. The relative abundance of methionine differs depending on the food type in question; it occurs in naturally high levels in foods such as sesame seeds, Brazil nuts, wheat germ, fish and meats.Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests.The research may help explain why 'dietary restriction'...

Statins Do Not Stop Advanced AMD

In the largest study of statin use by advanced AMD patients to date, researchers followed 744 patients enrolled in the Complications of Age-Related Macular Degeneration Prevention Trial (CAPT) for five or six years. Statin drugs are primarily used to lower cholesterol in CVD patients, but they also affect mechanisms thought to impact AMD, including reduction of the inflammatory marker C-reactive protein. Earlier studies on statins' effects had been inconclusive. All patients from the CAPT cohort study were at risk for advanced AMD, but none had developed advanced "wet" or "dry" AMD at baseline. The study was supported by the National Eye Institute."The CAPT data did not support a large effect for statins in decreasing advanced AMD risk in patients who already had large drusen in both eyes,"...

Aspirin May Offer Mild Protection from AMD

Records for 39,421women enrolled in the 10-year Women's Health Study (WHS) were used to evaluate the impact of low-dose aspirin on AMD risk. None of the women had AMD at the study outset; they were randomly assigned to take low-dose aspirin (100 mg on alternate days) or a placebo. It is known that low-dose aspirin substantially reduces the risk of serious blood vessel blockage, so researchers reasoned it might affect blood vessels that may play a role in AMD. Aspirin's anti-inflammatory and anti-oxidant effects were also considered potentially relevant. The research was supported by the National Eye Institute."Although our study found no large benefit from low-dose aspirin, the possible modest protective effect we did find warrants further study," said lead researcher William G. Christen,...

Aspirin, Tylenol May Decrease Vaccines Effect

With flu season in full swing and the threat of H1N1 looming, demand for vaccines is at an all-time high. Although those vaccines are expected to be effective, University of Missouri researchers have found further evidence that some over-the-counter drugs, such as aspirin and Tylenol, that inhibit certain enzymes could impact the effectiveness of vaccines.“If you’re taking aspirin regularly, which many people do for cardiovascular treatment, or acetaminophen (Tylenol) for pain and fever and get a flu shot, there is a good chance that you won’t have a good antibody response,” said Charles Brown. “These drugs block the enzyme COX-1, which works in tissues throughout the body. We have found that if you block COX-1, you might be decreasing the amount of antibodies your body is producing, and you...

Long-term physical activity has an anti-aging effect

Intensive exercise prevented shortening of telomeres, a protective effect against aging of the cardiovascular system, according to research reported in Circulation: Journal of the American Heart Association.Researchers measured the length of telomeres — the DNA that bookends the chromosomes and protects the ends from damage — in blood samples from two groups of professional athletes and two groups who were healthy nonsmokers, but not regular exercisers.The telomere shortening mechanism limits cells to a fixed number of divisions and can be regarded as a “biological clock.” Gradual shortening of telomeres through cell divisions leads to aging on the cellular level and may limit lifetimes. When the telomeres become critically short the cell undergoes death. The 2009 Nobel Prize in Physiology...

CPR WORKS W/0 M-TO-M BUT NOT W/O OXYGEN

People can survive cardiac arrest if they receive only chest compressions during attempts to revive them – as advised by the current American Heart Association guidelines. But they cannot survive without access to oxygen sometime during the resuscitation effort, research suggests.Scientists tested different scenarios in an animal study of cardiac arrest. Rats received either 100 percent oxygen, 21 percent oxygen – the equivalent of room air – or no oxygen (100 percent nitrogen) at the same time they received cardiopulmonary resuscitation (CPR).About 80 percent of the rats survived regardless of the percentage of oxygen they received along with chest compressions. However, in the group receiving no oxygen, only one animal could be resuscitated.Though these animals received the oxygen via ventilation,...
