Zusammenfassung

TLDRThe video critically examines the shift from traditional animal fats to vegetable oils in the diet and how this change may negatively impact health. It starts with William Osman's experiment on using sawdust as a deceptive rice substitute in Rice Krispy Treats to draw a parallel to how vegetable oils have quietly infiltrated our food supply. Historically, vegetable oils like Crisco were marketed as healthier alternatives and became widespread, with endorsements from the American Heart Association despite weak scientific backing. The video argues that consumption of vegetable oils, rich in polyunsaturated fats, correlates with increases in obesity, diabetes, and heart disease. These oils are suggested to produce toxic oxidizing products, contribute to mitochondrial dysfunction, and possibly affect lifespan, with references to historical studies like the Minnesota Coronary Survey highlighting the lack of evidence supporting the supposed health benefits of vegetable oils. The video's exploration involves historical context, scientific insights, and expert opinions casting doubt on these oils' safety, urging reconsideration of their place in the modern diet.

    Mechanical engineer William Osman experimented with using sawdust as a replacement for food ingredients, finding it could replace 15% of Rice Krispies without noticeable difference. This clever substitution is nothing compared to a global dietary shift replacing traditional fats with vegetable oils over 100 years, possibly leading to health issues such as obesity and diabetes. The production of vegetable oils like corn and cottonseed oil, starting in the late 1800s and popularized by Crisco, changed cooking habits away from animal fats, correlating with an increase in heart disease.

  • 00:05:00 - 00:10:00

    The American Heart Association endorsed replacing saturated (animal) fats with polyunsaturated (vegetable) fats in 1961 as heart disease became prevalent, despite little evidence linking saturated fat intake with heart disease rates. Vegetable oil consumption rose dramatically, replacing traditional animal fats and becoming a major part of diets, possibly contributing to health issues. Although some anecdotal evidence suggests removing vegetable oils from diets can improve health, it's largely based on correlations.

  • 00:10:00 - 00:15:00

    Research showed that animals with harder-to-oxidize cell fats live longer. Vegetable oils, high in oxidizable polyunsaturated fats, might affect human longevity similarly. The Minnesota Coronary Survey showed no longevity benefit from replacing saturated fats with vegetable oils, a result withheld for years. This challenges the belief that vegetable oils are healthier, as industry-funded research possibly skewed perceptions.

  • 00:15:00 - 00:20:00

    The overuse of easily oxidizable polyunsaturated fats like those in vegetable oils, linked to health issues like heart disease and Alzheimer's, poses risks. Industrial processing of these oils at high temperatures likely leads to oxidation, generating toxic byproducts. This long history of vegetable oil consumption is linked with modern health problems, as observed in various studies, including those noting quicker onset of heart disease in comparison to traditional animal fats.

  • 00:20:00 - 00:28:20

    Vegetable oils, abundant in modern diets, might contribute to diseases due to their high linoleic acid content, which oxidizes easily, potentially harming mitochondria. Despite evidence of health risks, these oils remain prevalent due to their low cost and subtle presence, like sawdust in food. Unlike sugar, whose absence is noticeable, vegetable oils blend into diets unnoticed, complicating public awareness and concern about their potential health effects.

  • 00:00:01
    In 2019, mechanical Engineer William Osman was  trying to figure out how to make use of a common
  • 00:00:07
    waste product - sawdust. A walk in the park left  him thinking: People eat plants all the time,
  • 00:00:13
    so why not eat trees? Osman decided to use sawdust  as a cheap alternative for a food ingredient.
  • 00:00:21
    Considering the American food most resembling an  actual piece of wood is the Rice Krispy Treat,
  • 00:00:27
    Osman decided to test how much of the  crisped rice he could replace with sawdust
  • 00:00:31
    without consumers noticing. Incredibly, he found  you could replace 15% of the rice with sawdust
  • 00:00:39
    without too noticeable of a  difference in the final treat.
  • 00:00:42
    "No idea. No way. I have literally no idea  there's sawdust in here. That's amazing."
  • 00:00:48
    Osman’s switcheroo was very clever, but pales in  comparison to the gigantic switcheroo pulled on
  • 00:00:53
    our global food supply over the past 100  years that would lead to today’s people
  • 00:00:58
    switching out a very common type of food  that we had eaten for thousands of years…
  • 00:01:04
    in favor of something edible but foreign  to the human diet and as I’ll argue here,
  • 00:01:09
    maybe even toxic - vegetable oil. "Mazola corn  oil, Crisco oil, vegetable corn and sunflower
  • 00:01:16
    oil." Low cost Vegetable oil is in everything  from packaged foods to restaurants and kitchens
  • 00:01:22
    across the world. "Vegetable oil. Canola oil.  Vegetable Oil. Canola oil." As consumption of
  • 00:01:26
    vegetable oils exploded, rates of obesity  and diabetes happened to explode with it.
  • 00:01:33
    To understand why some doctors and scientists  are saying vegetable oils make us fat
  • 00:01:37
    and diseased we need to look at some  history, some tapes hidden in a basement,
  • 00:01:45
    how vegetable oils are actually made and what  actually happens in your body when you eat them.
  • 00:01:53
    Let’s start in 1829 - thanks  to new machinery, it became
  • 00:01:57
    practical to make use of the leftover garbage  from cotton production - cottonseeds. The oil
  • 00:02:02
    extracted from cottonseed could be used as  fuel for lamps or lubricant for machinery.
  • 00:02:08
    In the early 1880’s, Thomas Hudnut invented a  mechanical way to extract oil from corn germ.
  • 00:02:14
    Up until then, corn germ was a  byproduct that corn refiners threw away.
  • 00:02:19
    In 1898, Corn Oil started to be  used as commercial cooking oil.
  • 00:02:24
    and in 1902, the Hudnut mills were selling  36 million gallons of corn oil per year.
  • 00:02:30
    In 1911, the soap maker Procter and Gamble  came out with a new product - “crystallized
  • 00:02:36
    cottonseed oil.” Crisco, looked a lot  like like the common cooking fat, lard.
  • 00:02:41
    You see, before 1900 or so,  everyone used virtually 100%
  • 00:02:46
    animal fats to cook. But Procter  and Gamble figured their newer,
  • 00:02:49
    cheaper product Crisco looked a lot like lard,  so why not get people to eat Crisco instead?
  • 00:02:56
    They launched a massive marketing campaign  presenting their cottonseed oil product
  • 00:03:00
    as the newer and cleaner cooking fat  that made cheap, better tasting foods.
  • 00:03:07
    Proctor and Gamble spent about 5  million dollars worth of today’s
  • 00:03:10
    money in 1911 to advertise crisco  and it became popular immediately.
  • 00:03:15
    Just the next year in 1912, sales  of crisco amounted to 2,600,000 lbs.
  • 00:03:22
    That same year, 1912, James B. Herrick  published a paper on what is thought
  • 00:03:27
    to be the first heart attack accurately  described in a medical journal. You see,
  • 00:03:32
    heart disease was actually a very rare  condition before the 1900’s or so.
  • 00:03:36
    Crisco continued to ramp up their advertising, and  in 1916, Crisco sales had reached 60,000,000 lbs.
  • 00:03:45
    "When the heart stops beating,  death is not in fact instantaneous."
  • 00:03:49
    In 1924 heart disease was rising and  the American Heart Association, the AHA,
  • 00:03:55
    was founded but remained quite small  and poorly funded for quite a while.
  • 00:04:00
    In 1945, soybean oil reached  1.3 billion pounds produced,
  • 00:04:05
    overtaking cottonseed oil as the  leading edible oil in the United States.
  • 00:04:10
    In 1948, The American Heart Association finally  got its big break when Procter and Gamble,
  • 00:04:16
    the makers of Crisco, designated  the AHA to receive the 1.7 million
  • 00:04:21
    dollars from Procter and Gamble’s radio contest.
  • 00:04:24
    "and as the American Heart Association's own  history book reads, it says ...and overnight,
  • 00:04:30
    millions poured into our coffers."
  • 00:04:33
    Heart disease was still on the rise and in In  1955, President Dwight Eisenhower had a heart
  • 00:04:38
    attack and the public was painfully aware  of just how big of a deal heart disease was.
  • 00:04:45
    Then just 6 years later in 1961, the American  Heart Association had the answer to heart disease.
  • 00:04:52
    The AHA recommended everyone to replace  saturated fats like those found in animal fat
  • 00:04:57
    with polyunsaturated fats like those found in  vegetable oils to prevent heart attack and stroke.
  • 00:05:04
    "It's 94% unsaturated, no oil is lower!2
  • 00:05:07
    By the way, saturated fat consumption  didn’t really correlate with rates
  • 00:05:11
    of heart disease before or after 1961  when the AHA made their recommendation.
  • 00:05:18
    And remember, we ate close to  zero grams of polyunsaturated
  • 00:05:22
    fat rich vegetable oils before  1900 when heart disease was rare.
  • 00:05:27
    "Okay so we went from zero in 1865 to 80 grams  a day. Now let me just say, this is an infinite
  • 00:05:36
    increase in vegetable oil consumption. That makes  this the single greatest change to nutrition
  • 00:05:42
    in all of history. I don't think  anything else can begin to compare.
  • 00:05:47
    A third of our diet is coming out  of factories that make these oils!"
  • 00:05:52
    Just like all these odd Corn Oil ads wanted us  to do, we added huge amounts of polyunsaturated
  • 00:05:58
    fat to our diet and today edible oil is now  a $100 billion dollar industry. So is this
  • 00:06:07
    massive increase in polyunsaturated fat rich  vegetable oil actually bad or just benign?
  • 00:06:14
    You can find various anecdotes here and there of  people clearing up ailments as bad as arthritis
  • 00:06:19
    or irritable bowel syndrome and losing plenty of  weight by removing vegetable oils from their diet.
  • 00:06:25
    Molecular Biologist Brad Marshall even came up  with a croissant diet where he'd totally removed
  • 00:06:30
    vegetable oils from his diet and lost plenty of  stubborn weight while eating croissants. Even Dr.
  • 00:06:37
    Cate Shanahan, Nutritionist for the LA Lakers  removed vegetable oils from their diet plan.
  • 00:06:42
    But these are just anecdotes so let’s move on.
  • 00:06:46
    As mentioned vegetable oil consumption happens  to correlate with diabetes and obesity…
  • 00:06:51
    but again we can’t get too excited,  this is just a correlation.
  • 00:06:57
    Next, It’s well known that the  size of an animal relates to
  • 00:07:00
    how long it will live - the larger an  animal, the longer it lives. But there
  • 00:07:05
    are plenty of outliers - for example  humans can live over a 100 years but
  • 00:07:09
    based on the size of humans, we should expect  a 70 kilogram human to live only 26 years. Also
  • 00:07:15
    the 35 gram naked mole rat lives about 5 times  longer than we should expect from its size...
  • 00:07:22
    Then… researchers found another way to  predict lifespan that accounts for some
  • 00:07:26
    of these outliers like humans and the naked  mole rat. They found that if the cells of the
  • 00:07:32
    animals are more made up of fats that are hard  to “oxidize” or break down, they live longer.
  • 00:07:38
    If the fats in theirs cells are easy  to oxidize, they don’t live as long.
  • 00:07:43
    And these vegetable oils we’re eating are  mainly comprised of polyunsaturated fat
  • 00:07:48
    which is very easy to oxidize.
  • 00:07:51
    Unfortunately for us, A 2015 review  in the American Society for Nutrition
  • 00:07:55
    found that that the key polyunsaturated fat in  vegetable oils, an omega-6 fat called linoleic
  • 00:08:00
    acid, accumulates and sits in our bodies the more  we eat it. The percentage of this linoleic acid
  • 00:08:06
    in people’s fat cells has nearly doubled from  a bit under 10% in 1960 to around 20% in 2005
  • 00:08:15
    But remember, we were already eating  plenty of vegetable oil by 1955.
  • 00:08:21
    "The next thing I'm going to show you I  searched for for 3 years. You know what
  • 00:08:26
    I wanted to know? What was the omega-6 fat in  anybody's adipose who was on an ancestral diet."
  • 00:08:32
    So what’s a normal linoleic acid  concentration? As Dr. Chris Knobbe discovered,
  • 00:08:35
    these Pacific Islanders who were eating a diet  unadulterated by vegetable oils the amount
  • 00:08:41
    of polyunsaturated linoleic acid was only 3.8%,  5 times less than what people are getting today.
  • 00:08:50
    "3.8% people. This is where we should  be. And this is what keeps you healthy."
  • 00:08:56
    So animals that have cells that oxidize easily  don’t live too long and we’ve been eating tons
  • 00:09:02
    of these easily oxidizing oils. But what data do  we have on humans, vegetable oils and lifespan?
  • 00:09:15
    "Dr. Frantz, I've heard the possibility that
  • 00:09:19
    there might be some very interesting  data in your father's basement."
  • 00:09:24
    This is cardiologist Robert Frantz on an episode  of Malcolm Gladwell’s revisionist history titled
  • 00:09:29
    “The Basement Tapes,” concerning  Robert Frantz’s father, Ivan Frantz.
  • 00:09:34
    “Ivan Frantz … chose… to devote  his life to studying heart disease;
  • 00:09:38
    specifically, to understanding the role of  cholesterol and blood lipids in heart attacks…”
  • 00:09:43
    Back in the 1960’s, Ivan Frantz conducted  a meticulously controlled study that would
  • 00:09:48
    shed light on what actually happens  when people cut out saturated fats
  • 00:09:53
    and eat polyunsaturated vegetable fats instead.
  • 00:09:56
    The study which would be called “The Minnesota  Coronary Survey” took years to set up and had
  • 00:10:01
    more than 9000 research subjects. Since  people were living in institutions,
  • 00:10:06
    they could control exactly what the people  ate. It ran for five years from 1968 to 1973.
  • 00:10:14
    “The patients in Frantz’s study would  go for their meals in the cafeteria
  • 00:10:18
    and get one of two trays - they looked  completely identical, but one tray was food
  • 00:10:23
    cooked with vegetable oil and everything low fat,  the other had everything cooked in saturated fat.”
  • 00:10:28
    “This was a beautifully organized study.  There was lots of money and nothing;
  • 00:10:33
    no holds were barred to try to do a good job.”
  • 00:10:37
    “To this day, it stands as one of the  most rigorous diet trials ever conducted.”
  • 00:10:42
    “So what does the Minnesota study show?  The patients on the vegetable oil died
  • 00:10:47
    did end up with lower cholesterol than the  people who ate food cooked with animal fats,
  • 00:10:51
    But the vegetable oil people didn't  live longer, which made no sense. They
  • 00:10:56
    were eating the kind of died everyone  believed should help you live longer.”
  • 00:11:00
    For whatever reason, Ivan Frantz  sat on his data for 15 years
  • 00:11:05
    until he finally published the results in 1989..
  • 00:11:09
    "And his study was all but  forgotten for a quarter century."
  • 00:11:12
    That is until Researcher at  the NIH, Christopher Ramdsen
  • 00:11:16
    tracked down Ivan Frantz son for the old tapes  containing the raw data from this study …
  • 00:11:22
    "The people who were over 65 who had been  on the diet for more than a year... The more
  • 00:11:29
    their cholesterol was lowered, the  higher the risk of an adverse outcome."
  • 00:11:34
    Here by "adverse outcome," he means death.
  • 00:11:40
    "People over 65 were dying faster if  they ate a so called healthy diet."
  • 00:11:46
    "There's no good evidence that reducing  saturated fat makes you live longer.
  • 00:11:51
    The best clinical trials reached  the opposite conclusion."
  • 00:11:56
    In Ramsden’s paper on the  Minnesota Coronary Survey,
  • 00:11:59
    he essentially says that the reason we assumed  vegetable oils are healthy up until now
  • 00:12:03
    is because researchers weren’t completely  publishing the actual results of their studies.
  • 00:12:10
    Let me remind you that vegetable oils are  everywhere - in many packaged foods, chips,
  • 00:12:15
    rice chips, crackers, salad dressings,  sauces, biscuits, mixed nuts, granola
  • 00:12:19
    bars … most mayonnaises are basically a jar of  soybean oil. I’m not in the U.S. at the moment,
  • 00:12:25
    but even most of these nicely packaged meals at  this expensive Japanese supermarket contain these
  • 00:12:31
    cheap vegetable oils. Most restaurants and chefs  use vegetable oils because they have a neutral
  • 00:12:36
    flavor,and well, they’re really cheap. People  have asked me what I think about plant-based meats
  • 00:12:42
    and one reason I’m not keen on them is because  they’re simulating the fattiness of real meat
  • 00:12:47
    with a bunch of vegetable oils. Canola, Soybean,  Grapeseed, Sunflower, Safflower, Corn and all
  • 00:12:54
    kinds of polyunsaturated vegetable oils have  replaced saturated fats in our food supply.
  • 00:13:02
    OK so Why? Why specifically would  vegetable oils be bad for our health? Well,
  • 00:13:08
    Average Americans today are eating 5 to  6 tablespoons of vegetable oils per day.
  • 00:13:12
    That’s around 700 calories of oil  filled with polyunsaturated fat.
  • 00:13:17
    It’s almost impossible to  get this amount naturally.
  • 00:13:23
    There’s so little oil per  ear of corn that it takes 98
  • 00:13:27
    ears or 12,000 calories of corn to get you  5 tablespoons of corn oil. 625 grapes or
  • 00:13:35
    2,800 sunflower seeds will get you 5  tablespoons of grapeseed or sunflower oil.
  • 00:13:40
    So a long industrial process is dedicated  to ripping oil out of tiny seeds.
  • 00:13:46
    As mentioned earlier, polyunsaturated vegetable  fats oxidize very easily. “Oxidize” simply means
  • 00:13:53
    to react with oxygen - this is how metals  rust and this is why meat that you leave out
  • 00:13:59
    turns brown after a while. Oxidation changes the  structure and properties of fats for the worse.
  • 00:14:05
    McDonald’s actually used to fry their fries in  Beef Fat, which was a really good idea because
  • 00:14:10
    it tasted better and the saturated fat in  beef fat is very resistant to oxidation.
  • 00:14:17
    It’s been common knowledge for a very long time  that it’s the unsaturated fats that are fragile
  • 00:14:22
    and polyunsaturated fats are far more  fragile than monounsaturated fats.
  • 00:14:28
    The main polyunsaturated fat in in vegetable oil  linoleic acid, is 40 times more prone to oxidation
  • 00:14:35
    than the monounsaturated oleic  acid you find in olive oil.
  • 00:14:40
    This is why your expensive bottle  of olive oil is dark green and
  • 00:14:44
    says to store it in a cool, dark place. Olive oil is mostly monounsaturated fat,
  • 00:14:50
    but 10% of it is fragile polyunsaturated fat
  • 00:14:53
    Since light, exposure to oxygen and  especially heat all speed up oxidation,
  • 00:14:59
    the olive oil will oxidize faster and worsen  the flavor if you don’t store it properly.
  • 00:15:04
    That’s because when fats oxidize, they produce  oxidation products that give the fat a bad flavor,
  • 00:15:10
    and these oxidation products are also toxic.
  • 00:15:14
    For example, the toxic Aldehydes are one  of the fat oxidation products. In fact,
  • 00:15:20
    acetaldehyde is thought to be what makes  you feel terrible during a hangover.
  • 00:15:24
    Professor of Bioanalytical Chemistry  in the UK, Martin Grootveld,
  • 00:15:28
    received some press for suggesting that  vegetable oils are not a healthy cooking oil
  • 00:15:33
    despite the National Health Service saying  so. His research showed that meals fried
  • 00:15:37
    in vegetable oil contain 100 to 200 times more  aldehydes than the daily limit set by the WHO.
  • 00:15:45
    If you must to fry foods at high  temperatures, the far more resilient
  • 00:15:50
    saturated fats like coconut oil or butter  produce far less of these harmful compounds.
  • 00:15:56
    Ironically, the reason McDonald’s switched to  frying everything in vegetable oil was thanks
  • 00:16:00
    to Phil Sokolof, a Nebraskan millionaire who  in 1985 began spending his personal fortune
  • 00:16:06
    on his crusade to stop others  from consuming saturated fats
  • 00:16:11
    which Sokolof thought were responsible for his  heart attack. His extensive anti-saturated fat
  • 00:16:17
    marketing campaign was effective and  eventually McDonald’s backed down and
  • 00:16:21
    swapped oxidation resistant Beef Tallow for  easily oxidizable Vegetable Oil in 1990.
  • 00:16:28
    The intense processing necessary to  simply get the oil out of tiny seeds
  • 00:16:33
    and into bottles easily damages them.
  • 00:16:37
    Heat is a great way to oxidize fats, and vegetable  oil is repeatedly heated long before it ever
  • 00:16:44
    arrives in a kitchen. There are many steps to  create edible oil and some involve very high heat.
  • 00:16:52
    The oil is heated to 80°C (176°F)  during the acid wash process
  • 00:16:57
    in the neutralization process, the  oil can get up to 95°C (200°F),
  • 00:17:01
    the bleaching process is carried out  between 90 and 110 degrees°C (230°F)
  • 00:17:08
    At this point the oil has oxidized so  much that it’s rancid and would taste
  • 00:17:12
    and smell awful if you ate it as is. This is why  there is a final intensive deodorization process.
  • 00:17:21
    During this extensive deodorization process, the  oil is heated once again and can reach as high
  • 00:17:26
    as 260°C or 500°F. That’s 125 degrees hotter  than the temperature needed for deep frying.
  • 00:17:37
    There’s something called the Israeli  paradox. Israel has one of the highest
  • 00:17:41
    omega-6 polyunsaturated fat consumptions  in the world; their omega-6 consumption
  • 00:17:46
    is 8% higher than the USA and 10-12% higher  than most of Europe. To quote this paper,:
  • 00:17:53
    “Despite such national habits, there  is a paradoxically high prevalence of
  • 00:17:57
    cardiovascular diseases, hypertension,  [type 2 diabetes], and obesity.”
  • 00:18:04
    Now the other thing about the fragile  polyunsaturated omega-6 linoleic acids
  • 00:18:09
    in vegetable oils, is they’re still problematic  even if not heated. Heat isn’t the only way to
  • 00:18:15
    oxidize vegetable oils. They can just oxidize  sitting on the shelf - walnut oil for example
  • 00:18:21
    which has plenty of linoleic acid, will  readily oxidize in just a matter of days
  • 00:18:26
    while simply sitting in  storage as you can see here.
  • 00:18:30
    Vegetable oils also oxidize while sitting in  your body, creating toxic oxidation products
  • 00:18:36
    like an aldehyde called 4-HNE. 4-HNE is in  fact considered to be the most toxic aldehyde
  • 00:18:42
    and this compound has been associated with  aging, heart disease, diabetes and alzheimer’s
  • 00:18:48
    Neuroscientist Testumori Yamashima has done  plenty of research on vegetable oils and 4-HNE.
  • 00:18:54
    He’s published multiple papers on  the damaging effects of this compound
  • 00:18:58
    and why people need to avoid vegetable oils cause  they oxidize into 4-HNE in our bodies. This book
  • 00:19:05
    of his is titled “Stop eating vegetable oils to  save your brain and blood vessels.” He’s even
  • 00:19:11
    gone as far as to say that the real culprit  behind Alzheimer’s disease is vegetable oil.
  • 00:19:17
    Now that's just the research of one  neuroscientist, but other research
  • 00:19:21
    at Lewis Katz School of Medicine at Temple  University found Canola oil in the diet to
  • 00:19:26
    be associated with worsened memory, worsened  learning ability and weight gain in mice.
  • 00:19:32
    Also, Alzheimer’s prevalence as happens to  correlate with vegetable oil consumption,
  • 00:19:37
    but again, this is just a correlation.
  • 00:19:43
    Do you ever feel more tired than  you should be? Like you’re just
  • 00:19:47
    low on “energy” and can’t concentrate for  seemingly no reason and you’re thinking
  • 00:19:51
    “Is it normal to require this much  coffee to muster the energy to function?”
  • 00:19:56
    But what is “energy” when talking about the body?
  • 00:20:00
    Here’s a Pop quiz: What do breathing, food,  cyanide and Star Wars all have in common?
  • 00:20:06
    Midichlorians. The microscopic  life forms living in the cells
  • 00:20:10
    of living things that determine  your propensity to use the force.
  • 00:20:15
    Actually No, but midichlorians are  obviously based off of mitochondria.
  • 00:20:19
    Mitochondria are found in nearly  all cells in the human body,
  • 00:20:22
    they are the powerhouse of the cell and the  reason you breathe and eat food. Mitochondria
  • 00:20:28
    use food calories and oxygen to create  energy in the form of a compound called ATP.
  • 00:20:35
    We are incredibly reliant on our mitochondria to  smoothly and efficiently produce massive amounts
  • 00:20:41
    of ATP energy. We need so much energy that if you  took all the molecules of ATP you made in a day
  • 00:20:47
    and put it on the scale, it would weigh as much  as you. We make our body weight in ATP every day.
  • 00:20:55
    If you messed up this energy supply, things  would go haywire rapidly . This is how cyanide
  • 00:21:00
    kills people so quickly - it damages the  mitochondria’s ability to make energy.
  • 00:21:05
    Unsurprisingly, some instances of  feelings of excessively low energy or
  • 00:21:09
    fatigue have been linked to  poor mitochondria function.
  • 00:21:13
    Evolutionary Biologist, Dr. Douglas C.  Wallace is arguing here that medicine
  • 00:21:18
    focuses too much on anatomy and  not enough on animation - that is,
  • 00:21:23
    the energy production necessary  to animate the anatomy.
  • 00:21:27
    Scientists are starting to see that mitochondrial  dysfunction may play a central role in the
  • 00:21:32
    development of many diseases, including heart  disease and Alzheimer’s. That’s not all that
  • 00:21:37
    surprising because the heart and brain require  massive amounts of energy to work properly.
  • 00:21:44
    It’s also well known that mitochondria  are dysfunctional in obesity and diabetes.
  • 00:21:48
    In fact, the world’s most prescribed  diabetes drug - metformin, which is
  • 00:21:52
    one of the few that also helps patients  lose weight, acts on the mitochondria.
  • 00:21:57
    So where does vegetable oil come into play?
  • 00:22:01
    Well, surprise surprise, vegetable  oils can damage the mitochondria.
  • 00:22:05
    To make this real simple, you can think of the  mitochondria as a conveyor belt at a factory
  • 00:22:11
    that’s pumping out ATP energy. After your  body pulls electrons from the food you ate
  • 00:22:17
    complexes and electron transporters  pass electrons down this conveyor belt,
  • 00:22:22
    the inner membrane of the mitochondria. This  results in protons being pumped up here and then
  • 00:22:27
    the protons get sucked into this  ATP synthesis enzyme to make ATP.
  • 00:22:33
    Now, the conveyor belt, the inner membrane,  has plenty of something called cardiolipin.
  • 00:22:38
    This is important because this is what’s damaged  when you consume plenty of vegetable oils.
  • 00:22:44
    When the linoleic acid from vegetable oils  accumulate in your body, you can get what’s
  • 00:22:49
    called a peroxidation cascade where kind of like  dominoes, one molecule of linoleic acid oxidizes
  • 00:22:56
    and produces a substance that can oxidize another  molecule of linoleic acid and this produces more
  • 00:23:01
    of that substance that can damage another molecule  of linoleic acid and so on and so on. It’s a chain
  • 00:23:08
    reaction. This chain reaction can go on to  affect the cardiolipin in your mitochondria.
  • 00:23:15
    As this study shows here, when rats eat  a linoleic acid rich vegetable oil diet,
  • 00:23:20
    markers of oxidized fat doubled … and in  the heart, the content of cardiolipin,
  • 00:23:26
    the stuff your mitochondria needs to  properly produce energy, was reduced 5-fold.
  • 00:23:32
    In this study, the cardiolipin of diabetic  and non-diabetic rats reduced drastically
  • 00:23:37
    when they were fed a vegetable oil diet,  and the mitochondria of the vegetable
  • 00:23:41
    oil fed diabetic rats completely  collapsed into these crumpled blobs.
  • 00:23:47
    Even the textbook Recent Advances  in Mitochondrial Medicine
  • 00:23:50
    acknowledges that omega-6 fatty acids like those  found in vegetable oil may damage various organs,
  • 00:23:57
    including the pancreas which would worsen  metabolic syndrome and type 2 diabetes.
  • 00:24:03
    So.. going back to the first study, what happened  to the normal rats whose mitochondrial cardiolipin
  • 00:24:09
    was reduced so much from eating vegetable oils?  In just four weeks, these rats had heart failure.
  • 00:24:16
    Developing heart failure that fast is very  alarming, but of course humans are not rats
  • 00:24:22
    so it’s not like eating a bunch of mayonnaise  will give you heart failure in a couple weeks,
  • 00:24:26
    it’s going to take a very long time  of consuming plenty of vegetable oil
  • 00:24:29
    for damage to become apparent. But, how long?
  • 00:24:33
    Well, let me mention one last study, the 1969  LA Veterans Administration Hospital study,
  • 00:24:40
    another very well controlled clinical diet trial
  • 00:24:43
    where people over 60 were given  either animal fats or vegetable oils.
  • 00:24:47
    To cut to the chase, the people in the  vegetable oil group were dying more… and
  • 00:24:51
    this was the case even though there were twice  as many heavy smokers in the animal fat group.
  • 00:24:57
    The interesting part is that this study  was so long - 8 years. And it took many
  • 00:25:02
    years to clearly see the negative  effect of the vegetable oil diet.
  • 00:25:07
    The study authors concluded that to truly  understand the negative health effect of vegetable
  • 00:25:11
    oils, maybe studies need to be much longer than  8 years, but most only lasted 5 years at best.
  • 00:25:20
    So to sum all this up: Vegetable oils rich  in the polyunsaturated omega-6 fat linoleic
  • 00:25:26
    acid displaced saturated fats which we had been  eating for thousands of years. The consumption
  • 00:25:33
    of these new oils happen to correlate with  rates of obesity, diabetes and Alzheimer’s.
  • 00:25:39
    Correlations are just correlations, but  it is well known that polyunsaturated fats
  • 00:25:43
    oxidize very easily, creating oxidation products  which are toxic to humans. Not only that,
  • 00:25:49
    but linoleic acid accumulates in  the body where it can oxidize,
  • 00:25:53
    creating these harmful oxidation products  and damaging our mitochondria. And lastly,
  • 00:25:58
    well controlled clinical trials have found worse  outcomes for people on a vegetable oil diet.
  • 00:26:05
    So Something I’ve been thinking about  is - if this is such a big deal,
  • 00:26:09
    why isn’t this a bigger topic? Why aren’t more  people interested in vegetable oils the way
  • 00:26:13
    people are interested in health effects of say  sugar? Well, I think the difference is sugar
  • 00:26:19
    tastes and makes us feel great. If you took it out  of your food, you’d definitely notice. So I think
  • 00:26:25
    some people intuitively think “this has got to be  too good to be true… maybe sugar is bad for me.”
  • 00:26:32
    But with vegetable oils, they’re a lot  like the sawdust in William Osman’s rice
  • 00:26:36
    krispy treats - they’re just there,  hard to notice, hiding in your food.
  • 00:26:41
    I mean, how often do you think about the fat  used to make your food? If someone swapped
  • 00:26:46
    the sugar in your coffee for stevia or Splenda,  you’d notice pretty quickly, but could you even
  • 00:26:52
    tell if the aromatic vegetables you ordered  were sautéed in canola oil instead of butter?
