  • butter supporters claim that cattle fed grains produce butter high in omega 6 .Higher than omega 3 And that it is the omega 6 that cause inflammation and heart disease Thus butter that is made by grass fed cows is healthy !!! Im not a supporter just saying what keto supporters believe !!!

    Nutrition, the visceral immune system, and the evolutionary origins of pathogenic obesity
    Mary Jane West-Eberhard
    PNAS January 15, 2019 116 (3) 723-731; published ahead of print December 31, 2018
    ((Based on these two salient facts, I propose the following “VAT prioritization” hypothesis regarding the evolutionary and developmental nature of pathogenic (visceral) obesity: Investment in VAT is prioritized relative to subcutaneous tissue (SAT) and sometimes other tissues in poorly nourished and therefore infection-prone individuals because of the immune advantage of maintaining VAT. Augmented nutrition then leads to visceral obesity and associated chronic disease, whose inflammatory nature may reflect the inflammatory immune responses of VAT.

    This perspective differs from previous discussions of obesity in attempting a coherent view of the relationships between the immune functions of VAT, its connection with inflammatory chronic disease, population differences in disease incidence, the role played by modern mass-marketed foods, and the evolutionary setting that may have favored adaptive fetal effects on patterns of fat allocation.))

  • Yeah butter was back for me since the 90s. The corn oil argument was hilarious to anyone with a knowledge of chemistry. Corn oil could not be corn oil after hydrogenating it. Even the corn oil turns out to be crap. Better to have saturated fat than too much PUFA Omega 6.

    And yeah, butter is bad if its involved in the SAD diet. The only reason is because its fattening in that context.

  • Very interesting stuff! It's downright criminal how 'scientists' can skew studies to give the results they want at the expense of the public's health. Thanks for putting in the time to research and post!!

  • Only Olive oil seems to get a good press – and this is a mono-unsaturate.
    To compare the dairy industry to the confectionary industry is disingenuous – if you suspect there has been a conflict of interest say so – don't make spurious analagies in an attempt to belittle.

  • You need to study science basics. Waiting for your some day make a video about bad science and about all the scientifics who have committed fraud in their investigations. Also make a video about the corporation who are behind more of the studies you use to brainwash people into your vegan agenda.

  • Problem is both the studies (for) and the presumptions you argue (against) are neither addressing the underlying cause. Heart disease is a energy failure problem, and cutting out any one particular substance isn't really a game changer in the outcomes. If you had done your research, and if you were a real doctor, which I doubt both, you would have realized that an increase in serum fatty acids is the cause of obesity, diabetes, and artery disease. Key words, serum fatty acids. This does not directly correlate to the inherent consumption of saturated fat, in fact it bears no relation to saturated fat period, but rather the total percentage of your calories coming from fat. With further analysis we find that most of the so called "healthy fats" which are the polyunsaturated fats, actually stimulate the randle cycle to a greater extent (then saturated fat) and block thyroid hormone secretion (thyroid peroxidase), thyroid carries proteins (transthyretin), and they also block the the conversion of T4 into active T3 in the liver. This thyroid antagonism is something that's entirely independent of polyunsaturated fatty acids, making them uniquely toxic in comparison to the monounsaturated and the saturated fatty acids. As any good cellular physiologist worth their weight could tell you, the cause of heart disease is a lack of T3 production which has a cascade of negative effect. Ranging from lipid peroxidation, increased serum cholesterol from a lack of conversion into pregnenolone, decrease in cardiac output, and the inability to retain magnesium and CO2 (both of which relax the cells and vasodilate the blood vessels).

    Broda Barnes MD, PHD, also demonstrated this by supplementing his patients with thyroid and getting a 94% reduction in artery disease and a 100% reduction in diabetes without attempting to control diet, exercise, cholesterol, or smoking. Mark Starr MD, PHD, also continues to demonstrate this today with his patients achieving a 100% reduction in artery disease and a 100% reduction in diabetes. Barnes had a dosage complication, and 4 of his patients did suffer minor heart attacks, but they were under dosing thyroid. Clearly you're paid off by the statin industry or some other frivolous company pushing outdated, inferior, "science". So to summarize, I would recommend people avoid the seed oils, nuts, seeds, etc. they're toxic and there's clear proof warm blooded mammalian creatures do not need them. The fact they completely inhibit a seed's metabolism should be a clear sign they're toxic. Get anywhere between 8% and 15% of your calories from fat for best results (mostly saturated, less then 2% from PUFA is ideal), focus most of your calories from sugar and starch which will keep thyroid hormone elevated and CO2 production high. There's no way you could physiologically run low on fat, your body will convert glucose into saturated fatty acids stearic acid and palmitic acid which can further be desaturated into a series of omega 9 fatty acids. Which, ironically, is another mechanism that clearly disproves this guy's claims. A low fat high carb diet is quite literally the purist form of saturated fat (no PUFA from lipogensis).

  • Healthy people and unhealthy people eat butter. Only the unhealthy people eat too much candy/sugar along with everything else. The common trend to being healthy is eating less in general but especially carbs and sugar

  • The amount and combination is essential. The issue of saturated fats might be in the combination with sugars.

    When we mix butter with sugar, then it mixes into a sticky cream, which is very tasty on desserts 🙂
    That saturated cream is not good inside of the cells. It's like glue. Saturated fats are not good with sugar in that logic.

    Good luck everyone to stay healthy and happy !

  • When will you use any legitimate studies that show things like butter in a real food , no processed sugar food diet? There is so much science in the past decade debunking the cholesterol heart health hypothesis you literally have to be internationally ignoring it to hang on to your misguided recommendations.

  • Can you please talk about your opinion on the study published last fall claiming that high ldl levels have no correlation with heart disease. I'm currently studying nutrition in school and that article frustrates me and I don't know what to make of it.

  • There's nothing better in this world than grass-fed butter! Your average body contains about 70000 calories in saturated fat, why? Because it's our bodies energy source of choice!

  • It's not about the butter, it all about when you do eat the butter and how often. People are addicted to food. You don't need to eat every day. I had my 1st meal in 11 days.

  • With all of the SUGAR that was added in the middle of the butter, I feel a little confused as to what this video was about. Butter Bad because the sugar industry lies with bad science. . . The connection was too weak and not as strong a video as most that I am used from Dr. G

  • Dr Greger, can you please do a video on Dr. Mozaffarian's study on dairy that states adults with higher levels of fatty acids overall were 42 percent less likely to die from stroke and high circulating levels of heptadecanoic fatty acid are associated with a lower risk of death from heart disease.

  • I feel really bad for all of you people who actually think eating the way our ancestors have been eating for hundreds if not thousands of years (eating butter for example) is bad for you. Many of you are probably getting angry and thinking: "wtf, look at the science! You're an idiot" while ignoring the science that shows butter is good. Listening to your body is the way to health, not listening to this BS with confounds galore and ignoring the other side of the debate in a biased way.

    Ah damn, I can't keep writing this, I have to go tell my 94 year old grandmother who is sharp and in good health to stop eating eggs/butter that she has been eating every day since she was a child so that she doesn't die. I hope I can save her life and I'm not too late! Later!

  • I came here for a scientific explanation of butter " how the body handles it" " how it is has nutrients " " is it good or bad fat" and all those .. all I found instead was what seemed like one sided vegan biased article .. I read pleanty of those ..

  • I will eat butter every day. You are a QUACK doctor. You said on another video our bodies handle the sugar in fruits differently than it does the sugar in candy. WTF? Are you even a real doctor? You believe it’s safe for children (who can’t make their own cholesterol) to eat a vegan diet?!?!? I sincerely doubt you’re educated on nutrition. Bye 👋

  • This is all bullshit. When a theory has no sort of scientific reality, it should not be accepted. Even when just one fact doesn't soddisfy a theory, it should be discussed. When there are many facts,…
    Superficial people often let themselves be dazzled by this appearance of logic. However the reality is another thing.

  • With the crazy amount of flat-out fucking fat pigs walking around do we really need to debate studies about what's making them fat as fuck? Just look around at what fat people eat and don't eat that same shit. Go whole plant food based and you won't be fat and you'll be nutritionally fulfilled.

  • Love your work! Your video's have been one of the motivators on my journey to a whole food and vegan based diet. Any comment though on the fact that vegan spreads like nuttelex that are processed but are still better than the whole food butter ?

  • "We know what is butter". Yeah, that's the only fact in this video. Yet, You assume that saturated fats are unhealthy and we eat too much of it. How do You know that?
    You're throwing at us epidemiological studies (lowest evidence worth) which are showing some correlations but not causations. Neither total cholesterol nor LDL are independent cardiovascular diseases markers.
