Wissenschaftler fütterten Menschen mit 130 g Fett einen Milchshake, um zu sehen, was es mit ihrem Gehirn angetan hat. Die Studie legt nahe, dass selbst eine einzelne motive Mahlzeit den Durchblutung des Gehirns beeinträchtigen könnte und möglicherweise das Risiko für Schlaganfall und Demenz erhöht. Dies war bei älteren Erwachsenen stärker ausgeprägt, was darauf hindeutet, dass sie möglicherweise anfälliger sind.

I’ve linked to the press release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
**We fed people a milkshake with 130g of fat to see what it did to their brains** – here’s what we learned
A greasy takeaway may seem like an innocent Friday night indulgence. **But our recent research suggests even a single high-fat meal could impair blood flow to the brain, potentially increasing the risk of stroke and dementia.**
After eating a meal high in saturated fat, levels of fat in the blood rise and peak after around four hours. At the same time, blood vessels become stiffer and lose their ability to relax and expand. This restricts blood flow around the body. But little is known about what happens to the brain during this time and how well its blood supply is protected.
The test meal was a milkshake, which we called “the brain bomb” because it consisted mostly of heavy whipping cream. The drink contained 1,362 calories and 130g of fat, mimicking the fat load of a fast-food takeaway.
Our findings confirmed previous research that has shown that a high-fat meal impairs the ability of the blood vessels linked to heart health to open in both young and old participants. These impairments reduced the brain’s ability to buffer changes in blood pressure. **This was more pronounced (by about 10%) in the older adults, suggesting that older brains may be more vulnerable** to the effects of the meal.
So how is the fat versus sugar debate nowadays? Is both, ie just calorie related?
How on earth did they get participants to down 130g worth of dairy fat without throwing up? A 250g pot of mascarpone has around 100g and I can’t imagine anyone spooning that up just like that.
That’s an insane amount of fat. Was there any sugar too?
It’s unfortunate studies like this get any traction. We’ve known for a very long time that sugar mixed with high fat causes huge problems. An interesting study would have been people on different diets and how fat affects them.
Studies like this are funded to get the clickbait title or to reenforce people’s perception on something; we already have studies that concluded what this study concluded, this study technically added nothing.
In eating over 250g of fat daily on a carnivore diet siet and my brain works better than ever. Funny they didnt concider it was the sugar impairing the brain function.
N = 20 and unless I missed it, they didn’t have a low-fat meal control. This could literally just be your digestion turning on in response to ingesting food.
now do a similar study with high carb milkshake
