After speaking to like. Nutritionists. I’m starting to think that most of the things people “know” about health are just cultural vibes

“Saturated fats give you heart problems” is actually like. Just folk wisdom. Comes from the same place that tells you that being cold causes disease.

Most of the advice I actually get from my nutritionist as a type 2 diabetic person who actually needs to lose some weight for my health is to just remember to take my meds, eat less simple carbs, eat fruits or vegetables, don’t overload on the salt, and drink a lot of water. Probably exercise too.

Of course your individual needs may vary but it’s really that simple in a lot of cases.

Exercise and vegetable eating also aren’t required to be chores. The idea that you need to suffer in order to eat better is just something we made up. Like put butter on your vegetables. Who cares. Butter is good.

Also açaí berries and kale are tasty and all but they ain’t special. “Superfoods” are also a cultural invention. Just eat a variety of things that you like. I unironically enjoy kale chips but they’re not inherently better for me than like. Cabbage.

Good thoughts, @iwrotesomeofitdown. At least half the vegetables in the grocery supply chain are either cabbage or nightshade, but some of them have more nutritionally useful compounds than others. Think of it like you’re trying to balance your humors. Do you need more green element? Then maybe get the kale/collards.

Also, isn’t most of the nasal immune system deeper in the warm parts of the head specifically because of this problem? I would also imagine that cold air being dry is also rough on the ol’ factories.

My new mutual @pacoyo5 pointed out that the link between saturated fats and cardiovascular health is known, so I did some quick digging. I’ve heard that the health panic over animal fats came from a place that was much more like folk wisdom than Randomized Controlled Trials, but that was the extent to my knowledge.

So I did what I always do when I need to know more about an academic subject and Wikipedia won’t suffice. I asked Perplexity, then checked the sources for greater context. And yeah, it does appear that there is a strong link between saturated fats and cardiovascular disease. The American Heart Association found that reducing saturated fats for polyunsaturated fats (like vegetable oil) is about as effective at protecting your heart as taking statins. A recent meta-analysis had more moderate conclusions, but even they agreed that saturated fats give you heart problems, at least some of the time.


Research is good, learning is good, unlearning is good, and when you make unqualified claims on the Internet, it’s usually seen as an open invitation to correct misunderstandings, which is also good.


Summary

“The idea that saturated fats cause heart disease, called the diet-heart hypothesis, was introduced in the 1950s, based on weak, associational evidence. Subsequent clinical trials attempting to substantiate this hypothesis could never establish a causal link. However, these clinical-trial data were largely ignored for decades, until journalists brought them to light about a decade ago. Subsequent reexaminations of this evidence by nutrition experts have now been published in >20 review papers, which have largely concluded that saturated fats have no effect on cardiovascular disease, cardiovascular mortality or total mortality. The current challenge is for this new consensus on saturated fats to be recognized by policy makers, who, in the United States, have shown marked resistance to the introduction of the new evidence. In the case of the 2020 Dietary Guidelines, experts have been found even to deny their own evidence. The global re-evaluation of saturated fats that has occurred over the past decade implies that caps on these fats are not warranted and should no longer be part of national dietary guidelines. Conflicts of interest and longstanding biases stand in the way of updating dietary policy to reflect the current evidence.”
