Dietary Fats and Cardiovascular Disease: An American Heart Association Advisory
- TheMagicHorsey 5y agoSo sounds like we should be replacing saturated fats with polyunsaturated fats. Further googling gives: Polyunsaturated fats are found in high concentrations in Sunflower, corn, soybean, flaxseed oils, Walnuts, Fish. Canola oil – though higher in monounsaturated fat, it’s also a good source of polyunsaturated fat.
- uhtred 5y agoI thought the Mediterranean diet was what we should all be eating, which would include a lot of olive oil. But that document suggests olive oil is high in monosaturated fats and thus not as healthy as canola oil (poly). Lolwut??
- TillE 5y agoThere's nothing surprising about canola oil being considered very healthy. Olive oil is also good.
- tpush 5y agoOlive oil has the most research behind it, thus scientists feel most comfortable advocating for it; but that doesn't mean that something like canola/rapeseed oil isn't also similarly healthy for you, given its fatty acid ratios and polyphenol content.
- tux3 5y agoMono-saturated doesn't make sense! Saturated means all the carbon atoms have as many hydrogen atoms as they can bear. Mono-unsaturated is off by one. It's generally regarded as more healthy, and olive oil is generally strongly recommended over saturated fats. Funnily enough, your body only knows how to synthesize saturated fats (palmitate), so your own natural fat is the "bad" one :)
- loudtieblahblah 5y agoThe AHA is full of shit. Monosaturated fats and even saturated fats are endlessly better for you than Omega6 PUFAs. Your daily fat intake should be more olive oil based, get some omega3s from fish 1-2x a week, and a moderate amount saturated fats. Omega6s are fine in the levels you get in Olive Oil (there's a little), or in nuts (macademia nuts being the lowest in omega6s) and say the odd avocado. To eat them in nthe levels that the West eats them in is toxic and there are endless studies about Omega6s being inflammatory and even contributing to insulin resistance in conjunction with sugar (yes.. a fat encouraging diabetes).
- Ekaros 5y agoOr maybe it is not really about the oil used, but other components in that diet... You need certain amount of fats for fat soluble nutrients. But I don't think lot makes too much sense compared to anything else.
- rgrieselhuber 5y agoI need a few downvotes, here’s the best book on which oils are healthy vs not: https://www.amazon.com/Deep-Nutrition-Your-Genes-Traditional/dp/1250113822 https://www.amazon.com/Deep-Nutrition-Your-Genes-Traditional...
- all2 5y agoYour gambit for downvotes appears to be successful.
- rgrieselhuber 5y agoNever fails on this topic.
- tpush 5y agoThat book is written by someone advocating "seed oils" being extremely unhealthy for you, a position that is not held by the relevant scientific community; actually exactly the opposite is true.
- loudtieblahblah 5y agoseed oils are unhealthy. and there are plenty of studies proving so.
- tpush 5y agoNo, this is simply not true.
- loudtieblahblah 5y agoWell you enjoy your Crisco, dude.
- rgrieselhuber 5y agoWell, as convincing as all your citations here may be, just going from first principles, I will continue to avoid the highly-processed, very profitable industrial waste known as 'seed oils.'
- nradov 5y agoThere are serious health concerns with soybean oil. https://www.universityofcalifornia.edu/news/americas-most-widely-consumed-cooking-oil-causes-genetic-changes-brain https://www.universityofcalifornia.edu/news/americas-most-wi...
- shadowgovt 5y agoOnly if you're deeply concerned about the health of mice.
- tpush 5y agoNo (non-quack/grifter) scientist is advocating the position that soybean oil is generally (as opposed to in e.g. exorbitant amounts, but then that goes for any fat) unhealthy for humans; quite the opposite in fact.
- rileyphone 5y agoPlease point out the quackery/grifting in https://academic.oup.com/advances/article/11/6/1489/5867525?login=true https://academic.oup.com/advances/article/11/6/1489/5867525?...

- ch4s3 5y agoIt changed gene EXPRESSION, not the underlying coding.
- loudtieblahblah 5y agoThe AHA is passing off horrible, unhealthy information. Omega6s in high concentration are horrible for you and are inflammatory.
- landemva 5y agoRapeseed oil was used as industrial lubricant and to fatten livestock before selling to slaughter. I won't be participating in the human experiment of consuming CANadian OiL.
- enraged_camel 5y agoIt appears this is from 2017. It also doesn't seem to tell us what we didn't already know, right?
- uhtred 5y agoI could drive myself crazy paying too much attention to this stuff. Eat a balanced diet, lots of plants, not too much added sugar, not too much saturated fat. Don't eat more than you need. Get some exercise.
- colordrops 5y agoThere seems to be lots of conflicting info out there on "good" fats. I think everyone agrees that monounsaturated fats are relatively good (e.g. olive oil), but there are two camps for saturated vs polyunsaturated. Each thinks the other fat is the root of many health problems. I suspect that different industries are behind the apparent dichotomy rather than science.
- tpush 5y agoNo, the science is very very clear on that questions: it's absolutely in favor of poly-unsaturated fats. There is however a pocket of quacks and grifters on the internet concocting conspiracy theories about nutritional organizations/guidelines to sell books and whatnot.
- voldacar 5y agoSo as americans have been eating more and more Omega-6 & PUFAs over the last century or so, they've been getting healthier and healthier, right? Maybe you can share some more predictions of your model.
- tpush 5y agoNo, that obviously doesn't follow. Current scientific thinking is that ultra-processed, ultra-palatable food high in both sugar and fat is likely responsible for the obesity epidemic. Of course, the fat in those foods is, most of the time, vegetable oils (because they're cheap & most of them are healthier than their animal counterparts). However, it absolutely doesn't follow that vegetable oil in particular is the driver here. If one switched all of the vegetable oil in ultra-processed, ultra-palatable food with animal fats the result will very likely be exactly the same, except for an increase in CVD due to the increased saturated fat content.
- colordrops 5y agoSounds like you are in one of the camps. If you are going to call out "the science" and speak disparagingly, you'd better provide references. Preferably comprehensive analysis, and not a few cherry picked studies. Otherwise you are just adding to the noise.
- TillE 5y agoIt's sad about coconut oil; coconut milk makes a really nice chia pudding, way better than the alternatives. It's the only bad part of my keto / low carb diet, otherwise my fat intake is overwhelmingly from olive oil.
- landemva 5y agoWhat is wrong with coconut oil? My breakfast is typically coffee with grass fed butter & coconut oil - in the coffee.
- loudtieblahblah 5y agoThe AHA is completely and utterly full of shit and just like most major bodies pushing nutritional standards, peddles some fairly dangerous information: https://www.health.harvard.edu/newsletter_article/no-need-to-avoid-healthy-omega-6-fats https://www.health.harvard.edu/newsletter_article/no-need-to... Seed-oils that wouldn't, largely, exist without industrial processes creating them as a byproduct (cottonseed oil, corn oil, soybean oil/Crisco, safflower oil, canola, etc.) are a HUGE driver of inflammation which is basically the root of every single disease - cardiac issues, cognition problems, neurological issues, autoimmune issues, cancer). And there's a lot of theory supporting evidence they explain why people in the 80s - who ate roughly the same amount of calories and had the same level of activity as people today... were on average, a lot lighter in weight. See: https://www.theatlantic.com/health/archive/2015/09/why-it-was-easier-to-be-skinny-in-the-1980s/407974/ https://www.theatlantic.com/health/archive/2015/09/why-it-wa... See: https://pubmed.ncbi.nlm.nih.gov/32008872/ https://pubmed.ncbi.nlm.nih.gov/32008872/ and a whole ton more studies too: https://duckduckgo.com/?t=ffab&q=omega-6+insulin+resistance&ia=web https://duckduckgo.com/?t=ffab&q=omega-6+insulin+resistance&... We've been peddled industry lies since the 1950s, largely by coroporations who are founded by 7th Day Adventists ( who are vegetarian by faith and founded companies like Kellog), that Omega-6 PUFAs are healthy and it's the Saturated Fats (animal fats, largely) that are bad bad bad. Yet, since the 1950s ..our health keeps getting worse and worse while omega-6 consumption goes up and up and up.. These companies have influenced nutritional boards and peddle the Ancel Keys, Seven Nations Study ( https://en.wikipedia.org/wiki/Seven_Countries_Study https://en.wikipedia.org/wiki/Seven_Countries_Study ) as the basis for Saturated Fats being the main driver behind CVD. But the study intentionally left off nations that would have radically changed the results and thus the conclusion. 50+ years of nutritional health has been guided by this b.s. Find me non-whole/fresh foods not jam packed with seed-oils. It's in marinades, tortilla shells, most bread, every body of packaged food you can imagine - chips, crackers, cookies, pre-made pies and cakes. Hell - i bought some salted pecans the other day from amazon and they were slathered in cottonseed oil for some reason. They're i n salad dressings, bbq sauces, wing sauces. It's even in dry-rubs for wings. Every. Thing. Mark my words - when history has had it's say, seed-oil delivering a level of omega-6s that the human body was never meant to endure long term, will go down as causing more suffering than sugar ever did, but made infinitely worse by the level of sugar we eat as well. The amount of omega6s we got from nuts or avocados or oats or whatever, was fine. Condensing it in the way we have and shoving it into everything has raised the titled the scale of consumption to toxic levels. And the AHA is Ok with this. The AHA, IMHO, is an organization with zero credibility when it comes to understanding human beings and lipids. They're a captured front for industry who would pass off Omega-6s as "heart healthy" and muddy the waters of the debate with shit quality studies.
- ccn0p 5y agoThis is from 2017 (although it appears to have some updates from 2020 with respect to the "Dietary Guidelines for Americans"). Am I missing something? What's the significance now? Just "this is still important so let's repost it"?
- tpowell 5y agoMy dad (62) just had big heart attack in January. 100% blockage in a vein covering 60%+ of his heart. The surgeon who put his stent in called his EKG “impressive”. He’s never eaten very well or exercised much, and the Mediterranean diet was one of the ones they recommended. My mom (always reading health books) decided to go for an extreme no fat, no oil(!) diet instead, which is difficult in practice. His labs six weeks later showed a greater than 100pt drop in his cholesterol and 30lbs+ of weight loss. He’s able to come off of his previous blood pressure medication, is sleeping better than ever and adding distance to his daily mile walk. Anyway, if you or someone you know is at high risk, turnarounds are absolutely possible with diet, and it might be worth further examining oils and “good fats” if your body doesn’t process cholesterol well.
- KSS42 5y agoWere there any changes to his carb intake? Did he also reduce use of simple carbs and processed foods?
- tpowell 5y agoJust about everything he ate changed, but he didn’t eliminate carbs. He ate homemade pizza with no cheese, crackers, pretzels… The mix absolutely included fewer processed foods, but pretzels out of a bag are processed, no? He looks forward to anything with flavor—salsa is popular, and small amounts of sorbet after dinner.
- voisin 5y agoSounds like he adopted the diet that Dr. Esselstyn recommends (http://www.dresselstyn.com/site/ http://www.dresselstyn.com/site/). There’s an excellent documentary, Forks over Knives, about his approach and he’s written a book that is awesome.
- tpowell 5y agoThat’s the one, thank you for linking.
- sk55 5y agoThis article implies the opposite of the claims in this study. https://www.bulletproof.com/diet/healthy-eating/good-fats/ https://www.bulletproof.com/diet/healthy-eating/good-fats/ "Saturated fat got some negative press back in the 1960s, when a scientist named Ancel Keys published research that claimed it caused heart disease. You’re probably familiar with the theory — that the saturated fat in butter, red meat, and egg yolks drives up cholesterol, which builds up in the arteries, blocking the flow of blood to the heart. The study was later debunked — it turned out Keys had manipulated the research to demonize fat. Later studies showed that saturated fat doesn’t raise levels of bad cholesterol (LDL) in the body.[15][16] Yet saturated fat is still shaking off its reputation as an artery-clogger. The fact is, saturated fat is the most stable fat that there is. A stable fat is the least likely to be damaged by oxygen (aka oxidized). Oxidized fats accelerate aging, cause inflammation in the body, and make weaker cell membranes."
- bitshiftfaced 5y agoFrom reference 16 (the link to 15 doesn't work): > Results: During 5-23 y of follow-up of 347,747 subjects, 11,006 developed CHD or stroke. Intake of saturated fat was not associated with an increased risk of CHD, stroke, or CVD. From OP's article: > Meta-analyses of prospective observational studies aiming to determine the effects on CVD of saturated fat that did not take into consideration the replacement macronutrient have mistakenly concluded that there was no significant effect of saturated fat intake on CVD risk. Their reference points to the same study (Patty W Siri-Tarino et al.) that the bulletproof article used. OP's article already acknowledges and disputes that information.
