As data trickle in, entrenched camps have emerged. Some researchers are convinced that many patients have an immune reaction to gluten or another substance in wheat—a nebulous illness sometimes called nonceliac gluten sensitivity (NCGS).
Others believe most patients are actually reacting to an excess of poorly absorbed carbohydrates present in wheat and many other foods. Those carbohydrates—called FODMAPs, for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols—can cause bloating when they ferment in the gut. If FODMAPs are the primary culprit, thousands of people may be on gluten-free diets with the support of their doctors and dietitians but without good reason.
Those competing theories were on display in a session on wheat sensitivity at a celiac disease symposium held at Columbia in March. In back-to-back talks, Lundin made the case for FODMAPs, and Alaedini for an immune reaction. But in an irony that underscores how muddled the field has become, both researchers started their quests believing something completely different.
Researchers at Curtin University in Australia observed 20 participants working at standing desks for two hours.
They found discomfort “significantly” increased for the lower back and lower limb regions, which correlates with previous research suggesting standing desk is responsible for swelling of the veins, which can endanger the heart.
Mental reactiveness also slowed down after roughly an hour and a quarter, however “creative” decision making was shown to marginally improve.

Perhaps most startling, children between the ages of 15 and 19 are 82 times more likely to die from gun homicide in the United States than in peer countries.
America has 4.4 percent of the world’s population, but almost half of the civilian-owned guns around the world. Research shows that the more guns in a country, the more gun deaths. Conversely, states with fewer guns have fewer gun deaths.
In suburban sprawl, you’re doomed to spending vast amounts of time at the wheel–time you cannot do much else with, and which you won’t get back. The nature of low-density automobile sprawl cities is that everything is insanely far away from everything else, so no matter what you do, you’re doomed to driving vast distances to see most friends, to commute to work and so on.
The subjects cycled through high-gluten, low-gluten, and no-gluten (placebo) diets, without knowing which diet plan they were on at any given time. In the end, all of the treatment diets - even the placebo diet - caused pain, bloating, nausea, and gas to a similar degree. It didn’t matter if the diet contained gluten. (Read more about the study.)
"In contrast to our first study… we could find absolutely no specific response to gluten," Gibson wrote in the paper. A third, larger study published this month has confirmed the findings.
It should be noted that this study is not about celiac disease — what it's saying is that if you don't have that specific disease you can eat all the gluten you want.
The fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy.
The country has outranked 162 others to take pole position in the Good Country Index, a league table based on 35 separate indicators from sources including the United Nations and the World Bank.
Sweden scores highest for positive lifestyle contributions including prosperity, equality, health and wellbeing, while also performing well culturally.
“We studied neighborhoods ranging in socioeconomic-status and culture. Those built with more activity-supportive environmental features had residents who did more physical activity. For example, transit access is a requirement for living a lifestyle that is less car-dependent and more active because it increases walking to and from the transit facility,” said James Sallis, PhD, lead study investigator and Distinguished Professor in the Department of Family Medicine and Public Health at UC San Diego School of Medicine.

In cardiovascular terms, the drop in heart rate from 1000 steps/day to 2000 steps/day is significant: a full 3 bpm decrease. And as step count increases, resting heart rate steadily drops—until you reach about 5000 steps per day. After that—6000, 7000, even up to 10,000 steps—the curve flattens.
