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."

This. Quit the knee jerk reactions and instant dieting habits swing based on the last episode of Dr Oz.

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.

Healthy food is tasty as hell once your palette has had a chance to get used to it again

No, when your palette gets used to it again, it becomes bearable ("as hell" is quite an apt a metaphor, actually) — but not especially tasty. Ice-cream or chocolate will still trump "healthy" and an ongoing effort of will is required to stick to broccoli.

I'd say, the results of the study show, that we increase cognitive abilities, when experiencing shortages, rather than decline, when eating, what we want. Which makes sense from evolutionary stand-point — if you are starving, you better think harder about finding sustenance...

But, however one spins the same facts, we better adapt to the 21st century of plenty. All of our evolution to day was spent with starvation constantly looming and occasionally hitting whereas today — and only for the last few decades — "starving" became a synonym for "dieting". And that we view the thinness as beautiful today is not a result of some evil conspiracy, but simply a reflection of what is healthy today — for a never-starving Westerner. Our super-thin ideals of today would not have survived even in the 19th century... The still-hungry Africans, for a counter-example, still think "fat is beautiful" and Mauritania even has a concept of "wife-fattening".

It is not "cultural" — they just still remember famine, whereas the "golden billion" has blissfully forgotten it.

Healthy food is tasty as hell once your palette has had a chance to get used to it again. All I can ever taste anymore with so much food in the States is either salt or sugar/HFCS. It's so fucking gross.

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).
