High-Fat Diet Messes Up Body Clock, Seriously

May 27, 2014 8:45 am 0 comments

imagesTiming may be everything, or at least a lot, when it comes to metabolic diseases like obesity and diabetes. And that, according to researchers at Texas A&M University, is why it’s important that our internal biological clocks run properly. Yes, Virginia, there is an internal biological clock. In fact, there’s one in every cell, and it controls the 24-hour cycles that tell our bodies when to sleep and regulate many physiological processes, including inflammation and metabolism. Now the important part: researchers at Texas A&M are convinced that a high-fat diet “dysregulates” our biological clock, and that such dysregulation can encourage inflammation and fat deposition and lead to insulin resistance and glucose intolerance. How do they know? A Texas A&M news release reports that the researchers fed two groups of mice different diets: one high-fat and one low-fat. Yes, you guessed right: they found that a high-fat diet changed the functioning body clock from a 24-hour cycle to a 30-33 hour cycle, particularly in immune cells involved in inflammation. This, in turn, can make critical inflammatory and metabolic processes occur at abnormal times throughout the day. It’s a bad thing.  “Keeping our body clock running properly is vital,” said study author David Earnest. “To promote health, we need to eat healthy foods, and more importantly keep a healthy lifestyle, which includes avoiding sleeping late and eating at night. Time your body right and it will work better.”

    Medical Errors Are Third Leading Cause of Death

    Thinking about going under the knife? Think about this: Researchers at Johns Hopkins who studied eight years of medical death rates believe that medical errors are the third leading cause of death in the United States. A Johns Hopkins news release reports that researchers put the number of people killed by errors somewhere north of 250,000. Why did it take so long to figure that out? Because, says says Martin Makary, professor of surgery at the Johns Hopkins University School of […]

    Ibuprofen And Healing, Probably Not

    Does ibuprofen, the choice of pain relievers for most athletes, promote healing, or does it just reduce pain? That’s the question that New York Times fitness columnist Gretchen Reynolds tackles, with help from  Stuart Warden, a professor of health science at Indiana University who has studied ibuprofen and tendinopathy, as tendinitis is now known. The short answer, says Reynolds, is no, ibuprofen does nothing for healing. The longer answer is more troubling: it may actually slow healing. As Warden points […]

    Exercise May Help Control Prostate Cancer

    Researchers offer no guarantees, but it looks like regular exercise increases the chances that prostate cancer will not spread beyond the prostate. HealthDay reports on an American Cancer Society study that included more than 10,000 men, aged 50 to 93, who were diagnosed with localized prostate cancer between 1992 and 2011. Researchers surveyed the men, asking about their physical activity before and after their diagnosis. Ready? The envelope please….the researchers found that men with the highest levels of exercise before their diagnosis […]

    Your Brain On Tylenol

    Acetaminophen, the active ingredient in Tylenol, does a pretty good job of relieving pain, but it also does some other things, like make it hard to spot an error that would otherwise be readily apparent. We know this because researchers at the University of Toronto gave two groups of 30 a target-detection task called the Go or No Go, in which players were asked to hit a Go button every time the letter F flashed on a screen but refrain […]

    Rich People Live Longer

    Yes, the rich are different from the rest of us. They live longer, for one thing. The New York Times reports on research published in The Journal of the American Medical Association showing that the gap in life spans between rich and poor widened from 2001 to 2014, with the top 1 percent in income among American men living 15 years longer than the poorest 1 percent. Yikes! And for women, the gap is 10 years. Wait, there’s more. In this […]

    Pot, Not Opioids, For Pain Reduction

    Smoking pot could be one answer to the country’s growing opioid abuse problem. Why do we say that? Because researchers at the University of Michigan have found that patients using medical marijuana to control chronic pain reported a 64 percent reduction in their use of more traditional prescription pain medications known as opioids. The researchers, who looked 185 patients from a medical marijuana dispensary in Ann Arbor, also found that pot users reported fewer side effects from their medications and […]

    Can Cat Poop Make You Crazy Mad?

    Cat poop, coveted by dogs and loathed by most humans, is suspected of making people mad, really mad. Researchers at the University of Chicago are convinced that people who are prone to explosive bouts of rage might be under the influence of toxoplasmosis, an illness caused by a parasite found in cat feces and undercooked meat. Strange but true. HealthDay reports that the study split 358 people into three groups–those with intermittent explosive disorder, those with a psychiatric disorder other than IED, […]

  • Fitness Pain The Ideal Interval Length

    The Ideal Interval Length

    We’ve all heard of interval training, in which short bursts of high intensity activity are alternated with less strenuous stints. Now comes Gretchen Reynolds, fitness writer for the New York Times, with answers, kind of, to two important questions about interval training: how long should an intense burst last?, and exactly how intense is “intense?” The answer, says Reynolds, is it depends. Mainly, it depends on how much pain you’re willing to put on yourself. Reynolds cites the research of Martin […]
