Although many parents are cautious about feeding any of their children an allergen if one shows a sensitivity to it, new research shows that just because one child is allergic to something doesn't mean siblings share the allergy.
Researchers in the new study, presented at the annual meeting of the American College of Allergy, Asthma, and Immunology, said while just over half of children show a sensitivity to foods their siblings are allergic to, misdiagnosis of an allergy can have negative consequences.
"The risk of food allergy in one sibling, based on the presence of food allergy in another, has never been completely clear," said Dr. Matthew Greenhawt, an allergist at the University of Michigan, in a press release. "This perceived risk is a common reason to seek 'screening' before introducing a high-risk allergen to siblings. But screening a child before introducing a high-risk allergen isn't recommended. Food allergy tests perform poorly in terms of being able to predict future risk in someone who has never eaten the food before. Our study showed that testing should be limited in order to help confirm a diagnosis, rather than as a sole predictor to make a diagnosis."

Drinking multiple cups of black tea (as opposed to green or other tea) with or without milk was linked to a substantially lower risk of fractures in older women who participated in the Calcium Intake Fracture Outcome Study(CAIFOS) and were followed for a mean of 5 years.
Specifically, in more than 1000 women with a mean age of 75, those who drank at least three cups of tea a day had a 34% lower risk of developing a serious osteoporotic fracture and a 42% lower risk of developing a hip fracture, compared with women who rarely drank tea, in this Australian trial.
"Previous studies, including our own, have demonstrated a beneficial effect of tea, a major source of dietary flavonoids, on bone structure," Dr Richard L Prince from the University of Western Australia, in Perth, and colleagues write, in an abstract presented as a poster at the American Society for Bone and Mineral Research (ASBMR) 2015 Annual Meeting. Now the current study suggests that black tea is associated with a lower risk of fracture in older women.

Pigments called carotenoids -- which give red or orange hues to carrots, sweet potatoes and orange peppers, or deep greens to produce like spinach, broccoli and kale -- may help ward off the age-linked vision ailment known as macular degeneration, researchers said.
Age-related macular degeneration (AMD) is one of the most common causes of vision loss, especially in the elderly. It affects the macula, the center part of the retina, and can lead to declines in sharp central vision and even blindness, experts say.
Scientists have already linked a variety of factors to the condition including genetics, smoking and nutrition, said Bernstein, who was not involved in the new study. However, treatment for AMD may be limited depending on the type of macular degeneration that a person develops, he said.

Lose weight while you sleep! You may have heard claims such as this connected to fad diet advertising. Well, it turns out that there may be some truth to the promise that getting a good night’s sleep can help with weight management. Research presented at the annual Food and Nutrition Conference (FNCE) of The Academy of Nutrition and Dietetics held in Nashville this year included studies on the effect of sleep deprivation on food intake. Bottom line: The less you sleep the greater your odds of weighing more. Registered dietitian Devon Golem, professor at New Mexico State University, explained that lack of sleep can disrupt the hormonal regulation of appetite leading to increased total calorie intake.
“When you’re exhausted you’re not making the best decisions about what to eat,” said registered dietitian Tamara Melton, clinical instructor at Georgia State University and spokesperson for the Academy of Nutrition and Dietetics. “You might seek out high-calorie high-sugar comfort foods or snack more often to stay awake. Plus you may be too tired to exercise.”
How much sleep is healthy? According to the National Sleep Foundation, adults should get between seven and nine hours of sleep. Meanwhile, the national average is six-and-a-half hours. “Sleep deprivation is an epidemic in the U.S.,” said Katherine Finn Davis researcher at the Children’s Hospital of Philadelphia.

Poor diet has emerged as the biggest contributor to early death around the world, according to new analysis from the leading authorities on the global disease, with red meat and sugar-sweetened beverages among the foods implicated in 21% of global deaths.
Smoking cigarettes still carries the highest risk factor of premature death in the UK, followed by high blood pressure and obesity. But the Institute of Health Metrics and Evaluation (IMHE) in the US says that a combination of dietary factors, from eating too few fruit and vegetables, nuts and whole grains to too much sodium and cholesterol, is taking a toll on health in the UK and across the globe.
The IMHE’s study found that the biggest contributor to early death globally is high blood pressure, in which age and family history play a part, but so do obesity, smoking, excessive salt consumption, lack of exercise and drinking large amounts of alcohol. In the UK, alcohol is also one of the top ten risk factorsassociated with the highest number of deaths for both men and women.

If you have a desk job, I'm sure by now you've heard the mantra, "sitting is the new smoking."
And, if you're like most working Americans, you're at that job for far more hours than you're playing sports, chasing after your kids or otherwise moving. That's why today, more than ever, it's important to make the best of how you spend those working hours.
One thing you do have control over? What you put in your mouth. Food fuels your brain as well as your body, so what's on your plate can affect your productivity. Here are eight foods (some of them deceptively healthy choices!) that can derail your on-the-job performance and focus: ...
A recent study by Swiss scientists highlights how important even minor wording changes in food labels can be. “If people lack the necessary knowledge to make informed decisions,” they note, “they have to rely on substitutes for knowledge.” And labels are among the most important food “knowledge substitutes” around: some carry a government’s authority. Also in play is the overwhelming trend right driving food-buying decisions at the moment: people hate artificial and want “natural” ingredients. These perceptions often have no scientific or nutritional basis, yet are all-important.
The study focused on sugar. Via an online interface, volunteers were shown two nutritional labels for a breakfast cereal and answered questions about them. One label listed “sugar” among the ingredients. The other listed “fruit sugar.” (Translation note: the study was conducted in German and employed the term Fruchtzucker, which technically means “fructose.” The authors say “fruit sugar” is the better English approximation because in German, Fruchtzucker evokes fruits and nature rather than the specific chemical.)
The scientists took steps to weed out misperceptions – in one part of the experiment, volunteers were shown the putative cereal box with an image of plain corn flakes, to indicate that the presence of “fruit sugar” did not mean the cereal contained fruit.
After a stress-free summer, heading back to the classroom – or the office – can create feelings of anxiety in many of us. And your diet may be partly to blame. Studies suggest certain foods can make you feel calmer while others can aggravate anxiety.
Components in foods such as carbohydrates, vitamins, minerals, antioxidants and even probiotic bacteria are thought to influence mood. Some are used to manufacture calming brain chemicals while others help regulate how the brain responds to stress.
While diet won’t cure anxiety, eating a steady fare of nutritious and well-balanced meals and snacks may help improve your mood. Use the following quick guide on what to eat – and what to avoid – to help lessen anxiety.

To examine excessive workout supplement use, the researchers recruited 195 men aged 18 to 65 years who worked out at least twice per week and had consumed at least one supplement in the previous 30 days.
They administered the Legal Appearance and Performance-Enhancing Drug Scale (LAPEDS), an online survey developed for the study that asked questions on subjects that included supplement use, self-esteem, body image, eating habits, and gender role conflicts.
The results showed that more than 40% of men had increased their use of supplements over time, and that 22% had replaced regular meals with dietary supplements not intended as meal replacements.

Workplaces that encourage healthy lifestyle practices are tied to fewer obese employees among millennials, according to a new study.
About 17 percent of young employees in workplaces that encouraged several healthy lifestyle practices were obese, compared to about 24 percent in spaces that promoted one or no healthy practices, researchers found.
Those environmental factors include support for colleagues, lunchtime yoga classes and food availability, she said in an email to Reuters Health.

There are lots of reasons people miss out on a good night’s sleep. Some are based on serious problems, including sleep apnea, depression or anxiety, said Cleveland Clinic’s Dr. Ketan Deoras, a psychiatrist with a specialty in sleep medicine. Other reasons could be medications, stress or what you’re eating or drinking.
“In the long term, if you don’t eat a healthy diet, you can become obese and you’re at risk for sleep apnea,” a serious disorder, with breathing interrupted during sleep, Deoras said.
Researchers are looking at other ways in which our diet impacts our bedtime. A 2013 study by the University Pennsylvania suggests that a good night’s sleep and a good diet are related. There aren’t yet conclusive findings, but experts point to some connections.

Another study showing an increased risk for cancer with drinking alcohol, even with just one or two drinks a day, has prompted renewed warnings on the health risks associated with alcohol consumption.
The new study, from an analysis of more than 150,000 healthcare professionals in the United States, found that overall, light to moderate drinking (alcohol intake of <15 g/day for women and <30 g/day for men) was associated with a small but nonsignificant increase in cancer risk in both women and men.
But this risk was more defined in specific populations. In men, the association was apparently driven by tobacco use. But for women, even one drink a day was associated with an increased risk for alcohol-related cancers, primarily breast cancer, and this was unrelated to smoking status.
The study was published online August 18 in the BMJ.
