College Football Players May Be At Risk of High Blood Pressure

College football players, particularly burly linemen, may develop high blood pressure in just one season of play, new research suggests. The study of 113 freshmen on Harvard's football team found that while none had high blood pressure at season's start, 14 percent did by season's end. All of the affected players were linemen. Experts said the significance of the blood pressure increase is not clear. The study did not follow the players long enough to see if their numbers fell again during the off-season, for example. "I think this is provocative, but we need further study to determine the significance," said Dr. R. Todd Hurst, of Mayo Clinic in Scottsdale, Ariz. http://www.nlm.nih.gov/medlineplus/news/fullstory_139141.html

E. coli Infection and Food Safety

Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract. The types of E. coli that can cause diarrhea can be transmitted through contaminated water or food, or through contact with animals or people. These are often called pathotypes. E. coli can cause diarrhea, urinary tract infections, respiratory illness, bloodstream infections, and other illnesses. Other kinds of E. coli are used as markers for water contamination—so you might hear about E. coli being found in drinking water, which are not harmful, but indicate the water is contaminated. It does get a bit confusing—even to microbiologists. http://www.cdc.gov/features/ecoliinfection/

Stigma Overweight People Face Could Spur More Weight Gain

Discriminating against a person because of their weight may actually increase the chances of that individual becoming obese, researchers report. People who experienced this so-called "weightism" are two and a half times more likely to become or stay obese later on, the researchers added. "Discrimination is hurtful and demeaning, and has real implications for physical health," said lead researcher Angelina Sutin, an assistant professor of psychology at Florida State University. http://www.nlm.nih.gov/medlineplus/news/fullstory_139016.html

Bone Marrow Fat May Raise Osteoporosis Risk, Study Says

Excess fat in blood, muscle and the liver may increase the risk of osteoporosis, a new study suggests. Researchers measured fat in more than 100 men and women, ageD 19 to 45, who were obese but otherwise healthy. Those with more liver and muscle fat had higher levels of fat in their bone marrow, the study found. Higher levels of bone marrow fat put people at increased risk of fractures, according to the authors of the study published online July 16 in the journal Radiology. http://www.nlm.nih.gov/medlineplus/news/fullstory_138755.html

As Years Spent Obese Rise, So Do Heart Risks

There's more bad news for overweight Americans: A 30-year study finds the risk for heart disease rises the longer someone is obese. "Each year of obesity was associated with about a 2 to 4 percent higher risk of subclinical coronary heart disease," said study lead author Jared Reis, an epidemiologist with the U.S. National Heart, Lung, and Blood Institute. "Subclinical" heart disease means damage to arteries that shows up in markers such as calcium buildup on arterial walls, but has not yet developed into symptomatic illness. http://www.nlm.nih.gov/medlineplus/news/fullstory_138761.html

Too Little Vitamin D May Hasten Disability as You Age

Older people with vitamin D deficiency may struggle with daily physical activities such as dressing or climbing stairs, a new study shows. It's estimated that as many as 90 percent of older people are vitamin D-deficient. The vitamin, usually absorbed through sunlight or diet, plays a key role in bone and muscle health, and a deficiency can lead to reduced bone density, muscle weakness, osteoporosis and broken bones. The study included more than 1,300 people, aged 55 to 88, in the Netherlands who were followed for six years. Participants' vitamin D levels were checked and they were asked about their ability to do routine tasks, such as sitting down and standing up from a chair or walking outside for five minutes without resting. http://www.nlm.nih.gov/medlineplus/news/fullstory_138798.html

Physical Activity Keeps the Brain Healthy

An active lifestyle has long been promoted as a way to keep the heart pumping strong. Now new research shows that physical activity may help to keep the brain robust as well, preserving areas critical for thinking and memory and possibly even helping to ward off Alzheimer’s disease in old age. Earlier studies have linked activities like walking and ballroom dancing to a lower risk for dementia. Exercise is known to boost cardiovascular health, and what’s good for the heart is good for the brain, the thinking goes. http://www.alzinfo.org/07/articles/prevention-and-wellness/physical-activity-brain-healthy

Calorie Advice on Menus Might Not Help People Eat Better

Making general calorie consumption guidelines available to patrons of restaurants where calorie count labels are already on the menu does not lead to better food choices, new research cautions. "The general inability of calorie labeling to result in an overall reduction in the number of calories consumed has already been pretty widely shown," said study lead author Julie Downs. "So that's nothing new. But in the face of that, there has been the growing thought that perhaps the problem is that people don't know how to use the information without some framework, some guidance," she explained. http://consumer.healthday.com/vitamins-and-nutritional-information-27/food-and-nutrition-news-316/dishing-out-calorie-recs-alongside-calorie-labels-on-menus-does-not-improve-food-choices-678431.html

Eating in the Fast-Food Lane

Does your family eat fast food at least once a week? About a third of all consumers do. That's okay sometimes, but many fast foods deliver a lot of calories and fat, yet they often come up short on vitamins, minerals, and fiber. The next time you head for the "fast-food lane," try one of these seven easy ways to eat smarter: Downsize. For fewer calories and perhaps less fat, sugar, or sodium, order regular, not supersize, portions. Color your sandwich! Add tomato, lettuce, and peppers to your burgers, subs, and deli sandwiches. Mind your buns. Order your sandwich with whole-wheat bread or buns if you can. Trim the trimmings. Go easy on creamy spreads, such as mayo, tartar sauce, and special sauce. Go for catsup, mustard, or barbecue sauce instead. Stay "side" wise. Split a small order of fries or onion rings. Order a salad (light on dressing) instead; go for slaw or fruit. Sip smart. Pick your beverage for better nutrition-milk for a calcium boost, or juice instead of soda. Look for options. Wraps, stir-fry bowls. - See more at: http://www.eatright.org/kids/tip.aspx?id=6442462211#sthash.3oUSEtjF.dpuf

Exercise Up in U.S., But So Is Obesity: Report

Although Americans are exercising more, the obesity epidemic continues to expand, University of Washington researchers report. Their nine-year study of data from two U.S. health surveys suggests that physical activity alone is not enough to combat the problem. "While physical activity has improved noticeably in most counties, obesity has also continued to rise in nearly all counties," said lead researcher Laura Dwyer-Lindgren, from the university's Institute for Health Metrics and Evaluation. The obesity problem is directly related to how much Americans eat, said senior author Ali Mokdad, a professor of global health at the Institute for Health Metrics and Evaluation. "Americans are not doing enough to control what they eat," he said. They still consume more energy than they burn off through exercise, he said. http://www.nlm.nih.gov/medlineplus/news/fullstory_138573.html

Too Much Fish Oil Might Boost Prostate Cancer Risk, Study Says

Eating a lot of oily fish or taking potent fish oil supplements may increase a man's risk of developing prostate cancer, new research suggests. Moreover, marine sources of omega-3 fatty acids may also raise the risk for aggressive prostate cancer, according to the study by scientists at the Fred Hutchinson Cancer Research Center in Seattle. "These anti-inflammatory omega-3s were associated with a 43 percent increased risk for prostate cancer overall, and a 71 percent increased risk in aggressive prostate cancer," said study lead author Theodore Brasky, a research assistant professor at Ohio State University Comprehensive Cancer Center in Columbus, who was at Hutchinson at the time of the study. Aggressive prostate cancer is often fatal, he added. http://www.nlm.nih.gov/medlineplus/news/fullstory_138583.html

Abdominal Fat Linked to Raised Heart, Cancer Risks

People with excessive belly fat have a greater risk of heart disease and cancer than those who have fat in other body areas, a new study finds. Researchers used CT scans to assess fat in the abdomen, around the heart tissue and around the aortic artery in more than 3,000 Americans, average age 50. They were then followed for up to seven years. During the follow-up, there were 90 cardiovascular events, 141 cancer cases and 71 deaths. Abdominal fat -- which typically indicates fat around internal organs -- was associated with an increased risk of heart disease and cancer, the investigators found. The findingshttp://www.nlm.nih.gov/medlineplus/news/fullstory_138580.html, published online July 10 in the Journal of the American College of Cardiology, might explain why people with a similar body mass index (BMI) but different body types have varied obesity-related health problems. BMI is a measure of body fat based on height and weight.

U.S. Lagging Other Countries on Many Health Measures

Life expectancy has increased in the United States over the last two decades, but Americans are also spending more of their lives in poor health, a sweeping new study finds. And despite being the biggest spender on health care in the world, the United States lags behind many other prosperous countries in the leading causes of premature death, including heart disease, violence, traffic accidents and diabetes. The main culprit behind the U.S. health problems appears to be eating habits, which are too low in fruits, vegetables, nuts and seeds, and too high in sodium, processed meats and trans fatty acids, according to the report. The new study is the latest in a series of reports by the Global Burden of Disease Study, a collaboration of 488 researchers in 50 countries. The group is sifting through staggering amounts of information to learn how different countries compare when it comes to life expectancy and overall health. http://www.nlm.nih.gov/medlineplus/news/fullstory_138575.html

Solid Food Timing for Babies Tied to Diabetes Risk

Infants who receive their first solid food either early or late -- before the age of 4 months or at 6 months or older -- are at increased risk of developing type 1 diabetes, new research suggests. Type 1 diabetes is on the rise worldwide, with some of the fastest increases among children younger than 5 years of age. Infants' diets are one major area of research into the origins of the disease, according to the background information in the study appearing online July 8 in JAMA Pediatrics. http://www.nlm.nih.gov/medlineplus/news/fullstory_138533.html

How to Read the New Sunscreen Labels

Look closely at the sunscreen you buy this summer, and you may notice some different wording on the label. This is the first summer that the US Food and Drug Administration (FDA)’s new labeling requirements are in effect. The new rules affect products that carry an SPF (sun protection factor) number, including not only sunscreen, but also makeup, moisturizer, and lip balm. Taking the time to learn about the new labels can help you better protect your skin from sun damage that can cause premature aging and skin cancer. http://www.cancer.org/cancer/news/features/how-to-read-the-new-sunscreen-labels

Heart Dangers of Low Vitamin D Levels May Vary

The heart risks of having low levels of vitamin D may hinge on what race or ethnicity you are, new research suggests. Specifically, the team of scientists found it might increase heart disease risk among white or Chinese individuals, but it does not seem to pose any cardiovascular danger to black or Hispanic adults. "We think that the differences are mainly due to biologic differences in vitamin D metabolism between race [and] ethnicity groups. However, future studies are needed to more carefully examine these potential differences," said study author Cassianne Robinson-Cohen, of the University of Washington, in Seattle. "Our results suggest that we should use caution in extrapolating results from studies conducted in European Americans to all race [and] ethnicity groups." Vitamin D is known as the sunshine vitamin because the human body produces it when exposed to the sun's rays. In recent years, vitamin D deficiency has been linked to a host of illnesses, including heart disease, certain cancers, osteoporosis, diabetes, Alzheimer's disease, schizophrenia and some autoimmune disorders. The Institute of Medicine recommends 600 international units (IU) per day for everyone aged 1 to 70 and 800 IU a day for adults older than 70. In the study, researchers measured vitamin D levels among more than 6,400 people of different ethnic backgrounds. None had evidence of heart disease when the study began. http://www.nlm.nih.gov/medlineplus/news/fullstory_138537.html

Singing Together Fosters Harmonious Hearts

When choir members sing together, their heartbeats become synchronized, researchers have found. The new study included 15 members of a high school choir whose heart rates were monitored while they performed three different choral exercises: monotone humming, singing a hymn and chanting a slow mantra. The music's melody and structure had a direct impact on the hearts of individual choir members. Singing in unison caused a synchronizing effect that led to singers' heart rates rising and falling at the same time, according to the investigators from the University of Gothenburg in Sweden. The findings were published in the current online edition of the journal Frontiers in Neuroscience. http://www.nlm.nih.gov/medlineplus/news/fullstory_138502.html

Eating fruits and vegetables tied to longer life

Eating fewer than five servings of fruit and vegetables each day is linked with a higher chance of dying early, according to a large study from Sweden. People who said they never ate fruit and vegetables died an average of three years sooner than those who ate plenty of apples, carrots and tomatoes, researchers found. Many public health organizations worldwide recommend eating five servings of fruit and vegetables a day, but previous studies have been inconclusive on whether meeting that guideline helps improve health and by how much, researchers said. The new study, published in the American Journal of Clinical Nutrition, shows the five-a-day recommendations are optimal, said Alicja Wolk, who worked on the research at the Karolinska Institute in Stockholm. Her team did not find any improvement in survival for people who ate more than five servings of fruit and vegetables each day, compared to those who just met the guideline. http://www.nlm.nih.gov/medlineplus/news/fullstory_138645.html

Vitamin D levels in USA peak in August, study finds

A bright spot for our health this summer is that we can get a dose of the sunshine vitamin. Even though our bodies can produce the most vitamin D in June, when the sun is highest in the Northern Hemisphere, vitamin D levels in the USA peak in August, according to a new study. The sun is lowest in December, but Americans' vitamin D levels bottom out in February. Researchers from the University of California-Irvine and the Mayo Clinic in Rochester, Minn., measured the level of 25-hydroxyvitamin D in 3.4 million blood samples collected weekly from July 2006 to December 2011 in the USA. The study was published in the journal PLOS ONE. http://www.usatoday.com/story/news/nation/2013/06/29/vitamin-d-levels-seasonality/2453955/

New 'Active' Video Games May Give Kids More Exercise

Newer-generation "active" video games give a slight boost to children's physical activity levels at home, according to a new study. Most video games are passive and no better than watching television in terms of getting youngsters to move and burn energy. Children in developed nations spend 38 to 90 minutes a day playing video games. But it wasn't known if active video games are any better. In this study published online July 1 in BMJ Open, Australian researchers looked at how removing passive games from the home or replacing them with active games affected the activity levels of 56 children, aged 10 to 12. For eight weeks, all video games were removed from the home. This was followed by eight weeks of being allowed to play passive video games and then eight weeks of being allowed to play active video games. http://www.nlm.nih.gov/medlineplus/news/fullstory_138356.html

Fiber-rich grains tied to lower diabetes risk

People who eat a diet high in fiber-rich whole grains are less likely to develop diabetes or heart disease, according to a review of past studies. The analysis was conducted for the American Society for Nutrition. In a position statement, the group said evidence suggests foods with cereal fiber or mixtures of whole grains and bran are "modestly associated" with a reduced disease risk. The strongest evidence for benefit came from cereal fiber, researchers said. That would include breakfast cereals as well as breads and brown rice with a high fiber content listed on the label, according to Teresa Fung, a nutrition researcher at Simmons College in Boston. "Cereal fiber may be one of the protective ingredients of whole grains that contribute to lower disease risk," Lu Qi, one of the study's authors from the Harvard School of Public Health in Boston, told Reuters Health in an email. http://www.nlm.nih.gov/medlineplus/news/fullstory_138381.html

Suicide Rate Higher for Adults Who Were Out-of-Shape as Teens: Study

Adults who were in good physical shape at age 18 were less likely to commit suicide than those who were less fit when they were younger, a new study has found. Researchers analyzed data from 1.1 million Swedish men born between 1950 and 1987 and underwent a medical exam for military service. The men were followed into adulthood. "Being in poor physical shape at 18 years of age, measured as the test results on an exercise bike during their medical exam for compulsory military service, can be linked to a risk of suicidal behavior as an adult that is 1.8 times greater," study co-leader Margda Waern, of the University of Gothenburg in Sweden, said in a university news release. The increased risk of suicide among men with poor fitness at age 18 was evident even 42 years later, according to the study, which was published online recently in the journal Psychological Medicine. http://www.nlm.nih.gov/medlineplus/news/fullstory_138360.html

Quitting Smoking May Boost Diabetes Risk Slightly in Older Women

Although quitting cigarettes helps the heart and lungs, a new study suggests that postmenopausal women who quit smoking need to guard against weight gain that can lead to diabetes. Still, "stopping smoking substantially decreases the risk of developing heart disease for postmenopausal women with and without diabetes," said lead investigator Juhua Luo, an assistant professor of epidemiology and biostatistics at the Indiana University School of Public Health in Bloomington. However, "because gaining more than 11 pounds may lessen the benefit, women should try to avoid gaining more than this amount," she said. "Our study shows that it is never too late to benefit from quitting smoking." The report was published in the July 3 issue of the Journal of the American Medical Association. http://www.nlm.nih.gov/medlineplus/news/fullstory_138364.html

Home Treadmills May Help People With Poor Leg Circulation

A home-based treadmill exercise program improved walking speed and endurance in people with poor circulation in the legs, a condition known as peripheral artery disease (PAD). That's the finding of a study that included nearly 200 PAD patients whose change in performance in a six-minute walk was measured over six months. Study patients who did the home-based treadmill exercise program increased their walking distance over six minutes by nearly 150 feet, compared with a decline of 36 feet among patients in a "control" group who did not do the exercise program. Participants in the exercise group also improved their maximum treadmill walking time by nearly a minute and a half, while the change in the control group was about 30 seconds, according to Dr. Mary McDermott, of the Northwestern University Feinberg School of Medicine, and colleagues. http://www.nlm.nih.gov/medlineplus/news/fullstory_138363.html

leep-deprived teens make poor food choices, a new study finds. "Not only do sleepy teens, on average, eat more food that's bad for them, they also eat less food that is good for them," study leader Lauren Hale, an associate professor of preventive medicine at Stony Brook University School of Medicine, said in a university news release. "While we already know that sleep duration is associated with a range of health consequences, this study speaks to some of the mechanisms, i.e., nutrition and decision-making, through which health outcomes are affected," she explained. http://consumer.healthday.com/vitamins-and-nutritional-information-27/food-and-nutrition-news-316/sleepy-teens-reach-for-fast-foods-first-677626.html

Health Tip: Why Take Folic Acid?

Folic acid is a type of B vitamin that's found naturally in foods including leafy vegetables and citrus fruits. While you're pregnant, it's important to get plenty of folic acid to help prevent birth defects. Here's advice from the Nemours Foundation: Women need 400 micrograms of folic acid daily during preconception and during pregnancy to help reduce the risk of neural tube defects (defects of the brain and spine). If you don't get enough folic acid in the foods you eat, take a folic acid supplement on the advice of your doctor. Getting enough folic acid is especially important for women who have already had a child born with a neural tube defect. http://www.nlm.nih.gov/medlineplus/news/fullstory_138455.html

Breast Milk Supply May Be Linked to Insulin Production: Study

Insulin plays an important role in making breast milk, according to a new study that may help explain why many mothers have difficulty producing enough milk to nurse their baby. The researchers describe how milk-producing glands become highly sensitive to insulin during lactation and how specific genes in the glands are switched on during lactation. RNA sequencing technology revealed "in exquisite detail" the blueprint for milk production in the mammary glands, said study corresponding author Laurie Nommsen-Rivers, a scientist at Cincinnati Children's Hospital Medical Center. The findings are published online July 5 in the journal PLoS One. http://www.nlm.nih.gov/medlineplus/news/fullstory_138459.html

Exercise Alone May Help Those With Type 2 Diabetes

Exercise benefits people with type 2 diabetes even if they don't make any other lifestyle or diet changes, a new study says. Dutch researchers conducted MRI exams of 12 patients with diabetes before and after they did six months of moderate-intensity exercise. Each week, the participants, who were an average age of 46, exercised between three and a half and six hours a week during two endurance and two resistance training sessions. The six-month exercise program ended with a 12-day trekking expedition, according to the study published online in the journal Radiology. http://www.nlm.nih.gov/medlineplus/news/fullstory_138138.html

Taxing on unhealthy food makes people buy less

A news study has found that labeling food and beverages as less-healthy and taxing them motivates people to make healthier choices. When faced with a 30 percent tax on less healthy items, consumers were 11 percent more likely to purchase healthy alternatives. Labeling choices as "less healthy" influenced purchases by 7 percentage points. Brian Elbel, Ph.D., MPH, assistant professor of Population Health and Health Policy at NYU and lead author on the study, said that the 30 percent tax rate was chosen as an extreme tax scenario.

Women on Hormone Therapy May Benefit From Extra Calcium, Vitamin D

Although there has been significant debate about whether calcium and vitamin D supplements are beneficial for older women, new research suggests that the answer may be yes for those who are taking hormone replacement therapy. Women using HRT who also took daily supplements of calcium and vitamin D saw a 40 percent reduction in their rate of hip fractures compared to women who took placebo supplements, according to the study. "We found that women who were on hormones had less hip fractures, and women who were on hormones and calcium and vitamin D supplements had even fewer hip fractures," said study author Dr. John Robbins, a professor of medicine at the University of California at Davis. http://consumer.healthday.com/bone-and-joint-information-4/fracture-health-news-322/women-taking-hormones-may-gain-from-extra-calcium-vitamin-d-677720.html

Bike sharing offers big fitness benefits for the little commute

With bike sharing plans rolling on asphalt from New York City to Budapest, experts say city streets are becoming as fitness-friendly as country trails. Even short cycling jaunts can make a difference in the health of city dwellers. "If you were driving a car and switched to biking, that 10 minutes going and coming a day would be a big deal," said Dr. Robert Oppliger, an exercise physiologist with the American College of Sports Medicine. Oppliger, an avid cyclist, said even a two-to-three-mile (3.2-to-4.8-km) spin can yield significant health benefits. "There's a lot of information coming out on something called active transport that compares traveling by bike or public transit to traveling by car," he said. "The benefits are significant the more mobile you are." Government guidelines recommend adults accumulate 150 minutes of moderately intense physical activity per week. Cycling, he said, can be part of that. http://www.nlm.nih.gov/medlineplus/news/fullstory_138132.html

Focus on Health, Not Fat, in Food Talks With Kids

There's a right way and a wrong way to persuade your adolescent to eat healthy and help avoid obesity, a new study suggests. Pointedly connecting food with fatness or talking about needed weight loss is the wrong way and could even encourage unhealthy eating habits, researchers report. Instead, discussions that focus on simply eating healthfully are less likely to send kids down this road, a new study shows. "A lot of parents are aware of the obesity problem in the U.S -- it's everywhere you turn -- but they wonder how to talk about it with their children," said study lead author Dr. Jerica Berge of the University of Minnesota Medical School in Minneapolis. She advises that parents "tell kids to eat more fruits and vegetables because eating them will make them healthy and strong.

Diet-Exercise Combo Doesn't Cut Heart Risks in Type 2 Diabetes Patients

Weight loss accomplished from diet and exercise does not appear to cut the risk of heart problems for people with diabetes, a new study finds. Lifestyle changes have long been the bedrock of treatment for type 2 diabetes. Doctors advise patients to eat carefully and stay active to help control blood sugar and cut the risk of long-term complications, which include at least a doubling in the risk for heart attacks and strokes. But the new study, published online June 24 in the New England Journal of Medicine, suggests that the benefits of diet and exercise may be more limited than previously believed. http://www.nlm.nih.gov/medlineplus/news/fullstory_138112.html
