  • A new Review proposes Saturated Fat is harmless and unfairly demonized. Does this reflect the scientific evidence? A look at the science of saturated fat, safe ranges and controversies.
    Saturated fat: villain and bogeyman in cardiovascular disease?
    Saturated fat is an emotional topic. Saturated fat raises cardiovascular disease if it's too high.
    Saturated fat isn’t bad. Health-promoting foods have Saturated fat.
    Replacing Saturated fat replaced with refined carbs doesn't help.
    Whole grains lower risk. Unsaturated fats also. PUFA, the lowest.
    Source of saturated fat matters. fish has saturated fat but also PUFAs. Dark chocolate is high in Saturated fat but its stearic acid which.
    we see benefit of saturated fat moderation in RCTs, usually PUFA is best. MUFA or carb, less consistent.
    UK Biobank: no evidence that saturated fat intake was associated with CVD, cardiovascular disease. Replacing saturated fat with MUFA or protein was associated with lower risk of death and CVD.
    Replacing saturated fat with starch or sugar (refined carbs) was associated with lower total death.
    PUFAs can come in fatty fish, nuts, seeds, vegetable oil, or in junk foods that contain PUFA oils. Saturated fat was associated with lower ischemic heart disease.
    saturated fat replaced with PUFA benefits CVD. PUFA consumption in place of saturated fat would reduce CHD.
    Linoleic acid replacing saturated fat associated with lower CHD and. Replacing saturated fat with polyunsaturated fat prevents CHD

    I think that until we stop talking about isolated nutrients (like Saturated Fat and Carbohydrate) and start talking about the entire food package (Rice vs Twinkies), confusion will abound. Every food is a combination of macronutrients in differing ratios. Most people are not eating isolated protein or drinking olive oil or eating bags of sugar (at least I hope they're not). Even something as simple as "dairy" could cover anything and everything from fat free yogurt to chocolate ice cream. So when someone asks, "Is dairy healthy?" you will get different answers and they are all technically correct. The problem is not that the information is contradictory (or controversial even), but that we aren't asking appropriately specific questions.

      The replacing saturated fats kinda did this. Its been clearly shown that replacing saturated fats whit whole grains is good. Same as replacing them with Omega 6.

      This. Also, I think most people fundamentally misunderstand how to properly use language. Word do-not dictate reality. Used appropriately, language is a 'map' each person overlays onto their non-verbal experience.
      When I look up into the day sky, and I see a bright circle in the air, I think, "sun". But the light I'm experiencing isn't "the sun" or "a sun", that experience is non-verbal. Words follow in the wake of some experience.

      Actually that IS the problem. Eating whole unprocessed foods means you are eating them in isolation. Sure you might combine a few unprocessed foods to make a meal. Eating fat and sugar in combination is a bad thing. I eat a couple of servings of fruit in a day but by themselves, never with a meal that also has fat. Then later in the day I eat a meal of animal foods with no sugar. I'm in amazing shape with amazing bloodwork. The problem is people thinking they need to constantly look at numbers. Just stop eating processed food and don't eat sugar and fat in combination and watch good health soar.

    Re: the paleolithic/ancestors argument.
    Look into the PUFA content of wild game. It's not the same as our modern beef...even grassfed. Elk, deer are all higher in PUFA and they're leaner -- maybe 1 g of sat fat per serving vs. almost 6 g for some beef. Our ancestors could have eaten 6x the amount of meat before reaching the levels of saturated fat we do today.

The analytical approach, depth of arguments, logical consistency and constant steel-manning is such a juxtaposition to the norm. With counter culture and 'toilet research' exploding, these videos are much more important than nutrition, they are a lesson on what actual knowledge, inquiry and expertise looks like.

Because of this you cant tell whos bullshitting or not so you prefer to write off research you don't like as simply corrupted.

      "Steel-manning". Nice word and you made me look it up: "The term “steelmanning” was coined by the philosopher Eli Dourado as a way of promoting more constructive and respectful dialogue in online discussions. By encouraging people to engage with opposing viewpoints in a more charitable and fair-minded way, Dourado hoped to promote more productive and meaningful discussions."

      It's disturbing that the "bogeyman" article was peer reviewed. It demonstrates that being peer reviewed is no guarantee of an article's reliability. The narrator of this video clearly discussed the flaws of the article: cherry picking studies, disregarding large rigorous studies that were directly in the timeframe and subject matter, and not giving weight to the quality of studies. It seems that every peer reviewed article needs to be scrutinized by someone with deep understanding of the field to determine if its conclusions are valid; which completely negates the purpose of the peer review process being an indicator of an article's quality.

OK, I’m calmed down now. Keep doing what I’m doing. Balanced diet. All things in moderation. Protein is good. Fiber is good. The less processed foods the better. No individual whole natural food is “evil” in moderation. No individual supplement, powder, nutrient or food is a panacea. Even a perfect diet will not replace the need for exercise - both cardio & strength training.

      Americans worry too much about what they eat.
      In the 90s all fat was evil now sugar is evil.
      For a while. Poly- unsaturated fats were wonderful now they’re evil it’s constantly changing.
      I think the thing is just do not over-eat and do not eat too many processed foods. But if you forbid yourself certain foods you are going to start craving them.
      I have friends that have done the keto diet and they could not stick to it and they gained back more weight than they ever lost and they said they look worse than ever.
      Only eat when you’re hungry and stop when
      You get that first full signal. It takes practice. Don’t think you have to “clean your plate”-you’re not a human garbage disposal💕
      Many yrs ago I read we should eat 2 meals a day. You could have something to drink in between, just get used to stop the chewing. You will honestly stop obsessing about food.
      Instead of lunch, clean your closet, run errands, go outside.

      My best friend her grandmother lived to 104 and she had a huge banana split every week, she was known for her fried doughnuts that she fried in lard. She was hilarious, very funny!
      I watched a video a few years ago of 107-year-old man and his main diet was condensed soup and whole milk. He did attend church regularly which was mostly white and he was African American,
      but he seemed very happy and loving. He drove his own truck.
      My MIL lived to 90.
      She was sharp as a tack. She never drank water only soda or tea or coffee. She was skinny as a rail. She ate pop tarts & breakfast cereals, she did try to eat one good meal a day with meat and vegetables
      Does anyone remember the nutrition professor (from Kansas, I think)who went on the junk food diet and lost a good bit of weight and all of his Numbers went down. Cholesterol numbers went down just from losing weight. I think that’s the thing don’t be overweight and cutting calories is the only thing that has ever been proven to prolong life. You can look that up, not antioxidants in fact antioxidants have been known to protect cancerous tumors, in the study in 2008 in the United Kingdom, you can look that up too.
      Harvard also did a study that said people who drank whole milk were thinner than people who drank skim milk. Because the people who drank skim milk were more hungry later and tended to eat more.
      I know this is too long. We just need to get back to common sense. I was a teen in the ‘70’s. I look at old concert footage, everyone was so thin. We did not obsess over food all the time. No one freaked out if you drank a soda.
      Every decade we have gotten more and more obsessed, and “they” say the population is more overweight than ever. I guess it is complicated.
      Oh, and I forgot, back around early 2000’s- It was eat every two hours small meals to keep your metabolism up-now fasting is popular.
      I never went for the eating two hours thing I knew that was not for me.
      Everyone live well and prosper!

      You have unpaid and sometimes apathetic reviewers against a well funded attempt to propagate misinformation.
      If you throw enough resources at it, the disinformation process is like save scumming in a turn based strategy game. Reviewers A and B actually do reference diving because they are professionals? Fine. Submit it to another journal. All you need is to roll a panel of apathetic reviewers. Let's say that 98% of the community would toss the paper back at your face, you reroll with another journal or another expendable first author. Assuming two reviewers, it'll take only 20 or so attempts even assuming a low level of apathy. (The journal in question is 22nd in citation metrics within its category of 136 publications. This is totally save scummable.)
      Edit: Now that I have described how to do a successful brute force attack on the peer review process (and I actually review things in several journals when asked), it is important to say that this would not be an issue without the modern attention based information economy. A scientist would just look at the paper title and its bibliometrics and laugh. A social media influencer or a science journalist would take the story and run with it.

    This was excellent. My experience is that I've followed the dietary guidelines since my youth, and it didn't do me any good because our understanding has changed so much over my lifetime. Additionally, so much of what we have been taught has been influenced by lobbyists. For example, my government mandated high school health class advised that pizza with everything on it was the perfect food (it included the four basic food groups approved by the lobbyists for the major industries). I was taught that a man should consume 3600 calories a day (influenced by political parties promoting the notion that the poor are malnourished and needed food stamps when they were probably eating an ideal diet!), and that we should count calories (not a good combination). I avoided vitamin supplements because that was the guidance - bad move for a light skinned person living in the north. I dutifully followed their advice to use margarine instead of butter back when that was full of trans fats, and I even worked on a dairy farm. I dutifully avoided egg yolks and thus denied myself K2.
    I have little doubt that your conclusion is correct as you make excellent arguments, and the Canadian plate looks like what is for dinner - however governments need to get out of the dietary guidance business, if for no other reason than they have been unduly influenced by lobbyists. The government has a conflict of interest. Additionally, they also don't adequately account for religious, cultural or genetic variations. I'll give two examples: that plate violates a kosher principle of mixing meat and milk, but nobody seemed to notice. Also, feeding people that evolved eating seals too many carbs has led to an epidemic of diabetes. They should just stay out of the business altogether because they are lousy at it and limiting the number of people listening to their advice limits the potential harm. I wish that I had ignored them, I'd be much healthier.

      Government guidelines haven't changed much here (Canada) in decades but people still don't follow them despite them being good. It's only when the Internet dude bros say to do the same certain things are okay then people listen:
      For decades the guidelines here said to watch portion size (and gave examples), eat lower sat fat, exercise moderate to vigorous 150 min a week, keep active and household activities count towards moving, eat fresh veggies, fruit, whole grains, limited dairy, and limited meats (to suggested servings), minimise sugar foods, alcohol. The only real change is more veggies than grains. And they dropped the specifics of exercise because no one was doing it.

      @@DetroitHomeInspector I’m just going to relate my personal experience and don’t want to undermine any decisions that you may have made. I struggled with a low fat diet and regular exercise for years going from having pre diabetes to full blown diabetes. My endocrinologist wanted to start me on insulin straight away. In the end we tried metformin and meds for my hypertension.
      This Christmas (December 22) I decided after losing perhaps 20lb over 4 years even with osempic that enough was enough. I did my own research:
      Prof Roy Taylor md
      Dr.David Unwin md
      Dr. Sarah halberg md
      Dr Eric Westman md
      In 5 months I’ve lost 35lb. I’ve stopped Osempic. My blood glucose and HgA1c normalised within 2 month.
      I’ve stopped taking synjardy but still take metformin 1000mg twice daily.
      My blood pressure is over the last month has averaged 110/70 so I may need to halve the dose or stop my losartan.
      I eat to satiety. Love what I eat.
      I’m eating an ultra low carb diet (20g).
      I almost never feel hungry and only eat once or twice a day.
      I have no cravings or feelings of being out of control. Bread , pasta rice etc are things I van totally live without.
      I make sure that I’m well hydrated.
      I now wear a continuos glucose monitor which has taught me loads along the way. For example I figured out day1 that porridge caused a massive and prolonged glucose spike.
      I’ve got a new wardrobe because my clothes were falling off me.
      I read a book called the last diet which taught me to accept days where I ate too many carbs and got a glucose spike.
      My wife, mother and children barely recognise me but are all so proud of my achievement.
      I’m going to stay on metformin for now even though I do not need it on this diet as it had demonstrable health benefits even if ny diabetes is in remission.
      There is a weight loss programme for everyone. For me it was avoiding ultra processed foods and eating low carb. Others may get there with a liquid diet or a low fat diet. The latter two didn’t work for me as I was always hungry and had cravings.
      If you are overweight then please understand that is not your fault.
      I wish you well.

    Problem is people don’t replace. They tend to eat all. Saturated, poly, carbs etc.

    Have you done, or could you do a video on Familial Hypercholesterolemia? My sister was vegan for 2 years and her cholesterol numbers didnt change one iota! My cholesterol is nearly 400 but i dont see the point in repeating her experiment until i know more.

    Thank you for a very educational and enlightening review. Among other issues, not knowing the field, I cannot know what studies the authors included and which they left out. Also, the issue of replacement is very important, but I would not think of it if I read the article on my own. I would love for you to invite evolutionary biologists, paleontologists, etc. to talk about the evolutionary aspects of nutrition. Thanks again.

    I’d like to see a study regarding saturated fat in a low carb setting.

    Appreciate your work Dr. Gil! I can't imagine the tediousness as you comb through these studies and abstracts.

    Being a science teacher for 34 years, I like your scientific methodology. Nutrition studies have many variables which you have pointed out & depending what you hold constant will strongly influence your results & conclusions. The media be it Covid, Ukraine or climate science wants something sensational; “throw the cat amongst the pigeons” & that is how we function. To garner the “truth” we need to statistically average over many peer reviewed published articles, just as you are doing. It is so important to pick out those nuanced differences & what you include & don’t make a large difference to you scientific researched conclusion. A great effort I thoroughly concur with your approach.
