High-Fat, High-Sugar Diet Can Lead To Cognitive Decline

An anonymous reader writes: Researchers from Oregon State University have completed a study into how the sugar and fat content of a diet relates to cognitive flexibility. They found that diets with high amounts of either led to a decline in cognitive function. "This effect was most serious on the high-sugar diet, which also showed an impairment of early learning for both long-term and short-term memory." After four weeks on a high-fat or high-sugar diet, the performance of mice on various mental and physical tests started dropping. One of the scientists, Kathy Magnusson, said, "We've known for a while that too much fat and sugar are not good for you. This work suggests that fat and sugar are altering your healthy bacterial systems, and that's one of the reasons those foods aren't good for you. It's not just the food that could be influencing your brain, but an interaction between the food and microbial changes."

    What’s often referred to as the “Western diet,” or foods that are high in fat, sugars and simple carbohydrates, has been linked to a range of chronic illnesses in the United States, including the obesity epidemic and an increased incidence of Alzheimer’s disease.

    The part about fat has being disproved in the last several years.

    This is just one study. We'll see if the results can be duplicated.

      Enjoy a few decadent meals each month, and balance that with plenty of salads, fruits, and vegetables. Avoid the processed food poison.

      Shite, you might even exercise once in a while.

      This and more.

      I have switched to low sugar, low carb, and started working out five times a week, two days of lifting, three days of cardio with running 5K or more on the weekends and managed to lose 40 lbs in 8 weeks. That's over 15% of my body mass.

      While the level of insanity that I endured for this is a bit much, I can attest to the fact that the amount of crap we add in American diets is excessive to the point of "we need to stop hurting ourselves"

      The biggest guidelines that I have for myself is if it's designed to sit on a shelf for a long time, it's not designed to be consumed and carbs are great, only if you have a plan to burn them off.

      Losing 300+ grams (11+ oz) a day is generally considered seriously unhealthy. Yeah, you started from a seriously unhealthy weight, but continuing a diet like that is a really bad idea.

    Well, if all you seek out and eat in the US is fast food, or the lower level chain restaurants, then sure, that's all you're gonna get.

    If you shop for and buy processed foods (the goop in the center aisles of the grocery store), again, yes, this is all your gonna get.

    But if you take a little time and look around, VERY good food choices can be had. And there is really NO excuse for only having bad foods at home. Ever heard of cooking? (and no, I don't mean popping something pre-made/frozen in the fucking microwave).

    And i quote:
    As the 21st century began, human evolution was at a turning point. Natural selection, the process by which the strongest, the smartest, the fastest, reproduced in greater numbers than the rest, a process which had once favored the noblest traits of man, now began to favor different traits. Most science fiction of the day predicted a future that was more civilized and more intelligent. But as time went on, things seemed to be heading in the opposite direction. A dumbing down. How did this happen? Evolution does not necessarily reward intelligence. With no natural predators to thin the herd, it began to simply reward those who reproduced the most, and left the intelligent to become an endangered species.

    There's something to be said for laziness. It's easy to cook up a healthy, tasty, low-effort inexpensive meal, but convenience seems to trump all of that for a good chunk of the populace. Nobody knows or cares how to cook up a decent meal.

    omce again human nutritional claims are being based on rodent model work, despite there being very little reason to expect the results to e replicable in humans. Stop giving PRELIMINARY and non-confirmed trials coverage as though they actually mean something. This trial only applies to mice at the moment. Maybe it can be extrapolated to all rodents in general, but the leap from rodents to humans directly is pure bull shit over reach.

    Well...breads would indeed be one of the 'goop' type highly processed foods found in the center aisles I was talking about.

    IMHO, it should be eliminated or at least made an extremely small portion of your diet. Try sticking to veggies, fruits and animal proteins. And yes, for some people I think a bit of dairy is ok. Just try to stick to foods that don't spike your blood insulin and for the most part, you should be ok.

    If the label has ingredients you can't readily decipher, or pronounce, likely as not, it should not be something you want to consume.

    Or, if the top ingredients include sugar or HFCS...you should likely pass that one by too.
