3 square meals a day paired with lean protein help people feel full during weight loss

ΩEating fewer, regular-sized meals with higher amounts of lean protein can make one feel more full than eating smaller, more frequent meals, according to new research from Purdue University."We found that when eating high amounts of protein, men who were trying to lose weight felt fuller throughout the day; they also experienced a reduction in late-night desire to eat and had fewer thoughts of food," said Heather J. Leidy, an assistant professor of nutrition and exercise physiology at the University of Missouri who was a postdoctoral researcher at Purdue for this study."We also found that despite the common trend of eating smaller, more frequent meals, eating frequency had relatively no beneficial impact on appetite control. The larger meals led to reductions in appetite, and people felt full....

Eat candy without adverse health effects

ΩGood news for candy and chocolate lovers: they tend to weigh less, have lower body mass indices (BMI) and waist circumferences, and have decreased levels of risk factors for cardiovascular disease (CVD) and metabolic syndrome, according to a new study(1) published in Nutrition Research.The findings are positive, but lead researcher Carol O'Neil, PhD, MPH, LDN, RD, Louisiana State University Agricultural Center, cautions it is all things in moderation. "We certainly don't want these results positioned as eating candy helps you to lose weight," she said. "This study adds to the evidence base that supports candy's role as an occasional treat within a healthy lifestyle."The study examined the association of candy consumption (broken into three categories: total candy, chocolate or sugar) on total...

Jon's Health Tips - Latest Health Research

ΩThis is driving me nuts. After my last report I went out and bought a lot of pecans. Now I have to go out and buy walnuts: 1. Walnuts are top nut for heart-healthy antioxidants"Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who did the analysis. "A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."Vinson noted that nuts in general have an unusual combination of nutritional benefits — in addition those antioxidants — wrapped into a convenient and inexpensive package. Nuts, for instance, contain plenty of high-quality protein that can substitute...

Walnuts are top nut for heart-healthy antioxidants

ΩA new scientific study positions walnuts in the No. 1 slot among a family of foods that lay claim to being among Mother Nature's most nearly perfect packaged foods: Tree and ground nuts. In a report here today at the 241st National Meeting & Exposition of the American Chemical Society, scientists presented an analysis showing that walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who did the analysis. "A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts...

Living at high altitude reduces risk of dying from heart disease

ΩLow oxygen may spur genes to create blood vesselsIn one of the most comprehensive studies of its kind, researchers at the University of Colorado School of Medicine in partnership with the Harvard School of Global Health have found that people living at higher altitudes have a lower chance of dying from ischemic heart disease and tend to live longer than others."If living in a lower oxygen environment such as in our Colorado mountains helps reduce the risk of dying from heart disease it could help us develop new clinical treatments for those conditions," said Benjamin Honigman, MD, professor of Emergency Medicine at the CU School of Medicine and director of the Altitude Medicine Clinic. "Lower oxygen levels turn on certain genes and we think those genes may change the way heart muscles function....

High consumption of omega-3s reduces obesity-related disease risk

ΩFish-rich diet linked to reduction in markers of chronic disease risk in overweight/obese peopleA study of Yup'ik Eskimos in Alaska, who on average consume 20 times more omega-3 fats from fish than people in the lower 48 states, suggests that a high intake of these fats helps prevent obesity-related chronic diseases such as diabetes and heart disease.The study, led by researchers at Fred Hutchinson Cancer Research Center and conducted in collaboration with the Center for Alaska Native Health Research at the University of Alaska-Fairbanks, was published online March 23 in the European Journal of Clinical Nutrition."Because Yup'ik Eskimos have a traditional diet that includes large amounts of fatty fish and have a prevalence of overweight or obesity that is similar to that of the general U.S....

Fiber Intake Associated With Reduced Risk of Death

ΩDietary fiber may be associated with a reduced risk of death from cardiovascular, infectious and respiratory diseases, as well as a reduced risk of death from any cause over a nine-year period, according to a report posted online February 14 that will be published in the June 14 print issue of Archives of Internal Medicine.Fiber, the edible part of plants that resist digestion, has been hypothesized to lower risks of heart disease, some cancers, diabetes and obesity, according to background information in the article. It is known to assist with bowel movements, reduce blood cholesterol levels, improve blood glucose levels, lower blood pressure, promote weight loss and reduce inflammation and bind to potential cancer-causing agents to increase the likelihood they will be excreted by the body.Yikyung...

Load Up on Fiber Now, Avoid Heart Disease Later

High-fiber diets during early adult years may lower lifetime cardiovascular disease riskA new study from Northwestern Medicine shows a high-fiber diet could be a critical heart-healthy lifestyle change young and middle-aged adults can make. The study found adults between 20 and 59 years old with the highest fiber intake had a significantly lower estimated lifetime risk for cardiovascular disease compared to those with the lowest fiber intake.The study will be presented March 23 at the American Heart Association’s Nutrition, Physical Activity and Metabolism/Cardiovascular Disease Epidemiology and Prevention Scientific Sessions 2011 in Atlanta, Ga. This is the first known study to show the influence of fiber consumption on the lifetime risk for cardiovascular disease.“It’s long been known that...

Physical activity decreases salt's effect on blood pressure

ΩThe more physically active you are, the less your blood pressure rises in response to a high-salt diet, researchers reported at the American Heart Association's Nutrition, Physical Activity and Metabolism/Cardiovascular Disease Epidemiology and Prevention 2011 Scientific Sessions."Patients should be advised to increase their physical activity and eat less sodium," said Casey M. Rebholz, M.P.H., lead author of the study and a medical student at the Tulane School of Medicine and doctoral student at the Tulane University School of Public Health & Tropical Medicine in New Orleans. "Restricting sodium is particularly important in lowering blood pressure among more sedentary people."Investigators compared study participants' blood pressure on two one-week diets, one low in sodium (3,000 mg/day)...

Episodic physical activity & sexual activity = increased risk of heart attack

ΩEpisodic physical activity and sexual activity are associated with an increase in the risk of heart attacks for a short window of time during and shortly after the activity. This association was less pronounced among persons with high levels of habitual physical activity.Full rep...

MOST READY-TO-EAT MEAT PRODUCTS: FEW HCAs- CANCEROUS COMPOUNDS

ΩNote: This press release ignores other cancer risks in hot dogs and all preserved meats: nitrites.Update - from Wkipedia:A principal concern about sodium nitrite is the formation of carcinogenic nitrosamines in meats containing sodium nitrite when meat is charred or overcooked. Such carcinogenic nitrosamines can be formed from the reaction of nitrite with secondary amines under acidic conditions (such as occurs in the human stomach) as well as during the curing process used to preserve meats. Dietary sources of nitrosamines include US cured meats preserved with sodium nitrite as well as the dried salted fish eaten in Japan. In the 1920s, a significant change in US meat curing practices resulted in a 69% decrease in average nitrite content. This event preceded the beginning of a dramatic decline...

Safflower oil each day might help keep heart disease at bay

ΩA daily dose of safflower oil, a common cooking oil, for 16 weeks can improve such health measures as good cholesterol, blood sugar, insulin sensitivity and inflammation in obese postmenopausal women who have Type 2 diabetes, according to new research.This finding comes about 18 months after the same researchers discovered that safflower oil reduced abdominal fat and increased muscle tissue in this group of women after 16 weeks of daily supplementation.This combination of health measures that are improved by the safflower oil is associated with metabolic syndrome, a cluster of symptoms that can increase risk for cardiovascular disease and diabetes.These new findings have led the chief researcher to suggest that a daily dose of safflower oil in the diet – about 1 2/3 teaspoons – is a safe...

Green & White Tea - Review

ΩWhite Tea vs. Green TeaWhen discussing white tea vs green tea, it is important to realize that they both come from the same plant, the tea plant Camellia sinensis. The main difference between the two types of tea is that the white tea leaves are harvested at a younger age than the green tea leaves. They both undergo very little processing. White tea is not fermented at all, while green tea is partly fermented. By contrast, black tea is fully fermented. Because they are so gently treated, white tea and green tea retain their content of beneficial antioxidants.However, studies have shown that the young, white tea leaves retain antioxidants in higher concentrations than green tea does. Studies have shown that white tea has a concentration of antioxidants that is three times higher than in green...

Omega-3 Reduces Risk of Age-Related Macular Degeneration

ΩOmega-3 Fatty Acid Intake Linked With Reduced Risk of Age-Related Macular Degeneration in WomenRegular consumption of fish and omega-3 fatty acids found in fish is associated with a significantly reduced risk of developing age-related macular degeneration in women, according to a report posted online that will appear in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals."An estimated nine million U.S. adults aged 40 years and older show signs of age-related macular degeneration (AMD)," the authors write as background information in the article. "An additional 7.3 million persons have early age-related macular degeneration, which is usually associated with moderate or no vision loss but does increase the risk of progression to advanced age-related macular degeneration."Using...

Does selenium prevent cancer?

Ω It may depend on which form people takeScientists are reporting that the controversy surrounding whether selenium can fight cancer in humans might come down to which form of the essential micronutrient people take. It turns out that not all "seleniums" are the same — the researchers found that one type of selenium supplement may produce a possible cancer-preventing substance more efficiently than another form of selenium in human cancer cells. Their study appears in the ACS' journal Biochemistry.Hugh Harris and colleagues note that although the Nutritional Prevention of Cancer clinical trial showed that selenium reduced the risk of cancer, a later study called the Selenium and Vitamin E Cancer Prevention Trial did not show a benefit. A major difference between the trials was the form of...

Tai chi beats back depression in the elderly,

ΩThe numbers are, well, depressing: More than 2 million people age 65 and older suffer from depression, including 50 percent of those living in nursing homes. The suicide rate among white men over 85 is the highest in the country — six times the national rate.And we're not getting any younger. In the next 35 years, the number of Americans over 65 will double and the number of those over 85 will triple.So the question becomes, how to help elderly depressed individuals?Researchers at UCLA turned to a gentle, Westernized version of tai chi chih, a 2,000-year-old Chinese martial art. When they combined a weekly tai chi exercise class with a standard depression treatment for a group of depressed elderly adults, they found greater improvement in the level of depression — along with improved quality...

Gardening For Your Health

ΩOlder adult gardeners report enhanced optimism, more physical activity, higher energy levels than nongardeners Does gardening contribute to quality of life and increased wellness for older adults? Researchers from the Texas A&M and Texas State Universities asked these questions in a survey of people aged 50 and older. The survey revealed some compelling reasons for older adults to get themselves out in the garden.Aime Sommerfeld, Jayne Zajicek, and Tina Waliczek designed a questionnaire to investigate older adult gardeners' and nongardeners' perceptions of personal life satisfaction and levels of physical activity. According to Sommerfeld, lead author of the study published in HortTechnology: "The primary focus of the study was to determine if gardening had a positive impact on perceptions...

Olive Oil's Health Benefits

ΩI knew that olive oil was good for me, but until I put together this review of recent research, I didn't realize just how good it is: Olive Oil Protects Against DepressionResearchers have demonstrated that the ingestion of trans-fats and saturated fats increase the risk of suffering depression, and that olive oil, on the other hand, protects against this mental illness.Luteolin from carrots, peppers, celery, olive oil reduces age-related inflammation in the brainA diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report. Luteolin (LOOT-ee-oh-lin) is found in many plants, including carrots, peppers, celery, olive oil, peppermint, rosemary and...

Curbing cholesterol could combat infections

ΩLowering cholesterol could help the body’s immune system fight viral infections, researchers have found.Scientists at the University of Edinburgh have shown a direct link between the workings of the immune system and cholesterol levels. A key immune hormone stimulated upon infection can lower cholesterol levels and thereby deprive viral infections of the sustenance they need to grow.Infection responseResearchers found that when the body succumbs to a viral infection a hormone in the immune system sends signals to blood cells. This causes cholesterol levels to be lowered. Cholesterol produced by our cells is needed for viruses and certain bacteria to grow. Limiting our body’s production of cholesterol would therefore curb the opportunity for viruses to thrive. DrugsScientists say that it may...

Aspirin's ability to protect against colorectal cancer may only apply to some

ΩElevations in novel inflammatory marker predict who may benefit from preventive treatmentThe reduced risk of colorectal cancer associated with taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) may be confined to individuals already at risk because of elevations in a particular inflammatory factor in the blood. In a paper in the March issue of Gastroenterology, investigators from Massachusetts General Hospital (MGH) and Dana-Farber Cancer Institute report finding that higher baseline levels of a novel inflammatory marker indicated increased risk of developing colorectal tumors and also predicted who might benefit from taking aspirin or NSAIDs."These findings suggest that a blood biomarker may be helpful in deciding whether individuals should take aspirin or NSAIDs to reduce...

High Levels of 'Good' Cholesterol May Cut Bowel Cancer Risk

ΩHigh levels of "good" (high density lipoprotein) HDL cholesterol seem to cut the risk of bowel cancer, suggests research published online in Gut.The association is independent of other potentially cancer-inducing markers of inflammation in the blood.The researchers base their findings on participants in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. This is tracking the long term impact of diet on the development of cancer in more than half a million people in 10 European countries, including the UK.Some 1,200 people who developed bowel and rectal cancers -- 779 bowel and 459 rectal cancer -- after agreeing to take part in EPIC were matched with another 1,200 participants of the same age, gender, and nationality.Blood samples taken when they joined the study,...

Veggies, Green Tea Work in Cancer-Fighting Diet

ΩYour vegetables are good for you, says a research review published by scientists from the University of Alabama at Birmingham in the journal Clinical Epigenetics.In particular, vegetables such as broccoli and cabbage are filled with compounds that could help reverse or prevent cancers and other aging-related diseases as part of the “epigenetics diet,” a new lifestyle concept coined after the article’s publication.“Your mother always told you to eat your vegetables, and she was right,” says co-author Trygve Tollefsbol, Ph.D., D.O., a biology professor in the UAB College of Arts and Sciences. “But now we better understand why she was right — compounds in many of these foods suppress gene aberrations that over time cause fatal diseases.”Epigenetics is the study of the changes in human gene expressions...

Mediterranean diet: A heart-healthy plan for life

ΩNew study shows it's a sound recipe for healthy livingThe Mediterranean diet has proven beneficial effects not only regarding metabolic syndrome, but also on its individual components including waist circumference, HDL-cholesterol levels, triglycerides levels, blood pressure levels and glucose metabolism, according to a new study published in the March 15, 2011, issue of the Journal of the American College of Cardiology. The study is a meta-analysis, including results of 50 studies on the Mediterranean diet, with an overall studied population of about half a million subjects."The prevalence of the metabolic syndrome is increasing rapidly throughout the world, in parallel with the increasing incidence of diabetes and obesity, and is now considered a major public health problem," said lead...
