what if a $200 billion food ingredient is shrinking our brains and making us dumber from Ranch to Italian the dumbing down of America making our kids Dumber brain is permanently stunted by food that you consume in the 1930s a Polish farmer came to Canada with a plant that has seeds that produce an oil that was great for lubricating Machinery Canada produced tons of this stuff to lubricate ship engines during World War II but after World War II they didn't need all that lubricant anymore and we stuck with all these seed producing plants also they had tons of Machinery left over because to produce just a tablespoon of oil you [Music] need 70,000 seeds to get this tiny amount of oil they ran the seeds through a long industrial process with high pressure forcing out the oil to a second extraction 70-minute wash with a solvent they wash the oil with sodium hydroxide they bleach it then you use a steam injection heating process to remove the canola odor and they then sold it as cooking oil for humans healthy cooking with new misola R blend MAA canola canola oil is now the most commonly used cooking oil today you probably have it in your pantry seed oils seed oils the most unhealthy ingredients that we have seed oils are of the devil and when you want to stop using them you can't they're in every food in 1865 we ate 0 g of vegetable oil but now the average American consume 720 of the calories in their diet from these highly processed oils every day now vegetable oils also called seed oils contain a very specific type of fat that for 99% of human history we didn't eat that much of and the human brain is mostly made of fat it's about 60% fat so the question is could eating a ton of all this processed seed oil fat be affecting our brain and our intelligence so we eliminated Alzheimer's Disease by eliminating vegetable oil corn oil and soil from the animal diet and putting in large doses of vitamin E and selenium by the way if you're interested in reducing the negative health effects of these seed oils make sure and watch the video to the end cuz I've got a free gift for you now let's rewind a little bit damage to children like brain damage learning disabilities back in 1979 researchers was shocked to see a notable decrease in the average IQ of children in Massachusetts not only were these kids slower at learning but something was affecting their brain to where they were more distractable hyperactive impulsive and easily frustrated in the 1920s Thomas Midgley had just made a new product for the automotive industry that he predicted would make billions of dollars modern gasoline gives the greater performance that product was tetraethyl lead which was used to make leaded gasoline lead gasoline was far more profitable from the 1920s cars all over the country were pumping the poisonous lead into the air every day mounting medical evidence that lead is damaging children's brains this dramatic change in the air led to a decline in the IQ of children luckily our brains are now safe from this because Leed gasoline was phased out starting in 1973 2 years from now cut lead by 91% so then what happened after 1973 IQ scores seem to be drifting up but there's also evidence that the effect is slowing down and possibly reversing oh boy in 2018 Norwegian researchers revealed data that IQ scores started to slightly decrease for men born after 1975 the lead author Rosenberg says that similar studies in Denmark Britain France the Netherlands Finland and Estonia all found the same thing a trend of decreasing IQ scores now raborg points out that someone might criticize his finding saying that because IQ has a lot to do with genetics maybe it's just more dumb people or having more kids but he says no it has to be environmental factors because they found the same downward Trend in IQ within families DrMichael Crawford director of The Institute of brain chemistry and human nutrition says that based on current Trends we are heading for an idiocracy there are tons of factors to IQ but evidence is piling up that a different cheap and profitable invention is now polluting our brains this completely new and unnatural product has created a $212 billion industry and it's not in the air but our food supply DrMichael Crawford's data suggests that a new specific type of fat added to the global food supply may be de evolving our brains now that's a huge claim so let's take a look at what makes our brains so big and smart in the first place Lucy the worst rated movie of Scarlett Johansson's career has a scene where her brain becomes so powerful that she can travel back in time allowing her to meet a human ancestor also named Lucy you see Lucy is a member of a species of primier that really existed 3. 2 million years ago primate's brains leading up to Lucy's kind had been growing very slowly and steadily however something happened around 2 million years ago brain size started mysteriously increasing way faster ending up with humans having massive brains way ahead of schedule in fact the human brain is so abnormally large that if height increased at the same rate that brain volume did female humans height today would be around 8. 5 ft or 260 CM so why did this happen and why are satans like dolphins Orcas and whales so smart and why are rhinos cows and horses so dumb one theory is that early humans essentially figured out how to cook wild potatoes tubers which gave them plenty of calories to fuel their big energy hungry brains the human brain takes up a whole 20 to 25% of our calories so an efficient source of calories was very important except this doesn't make that much sense because wild potatoes don't have any of the important nutrients the brain needs to grow they're just calories hunting would be a much better reason for why our brains grew animal meat and organs would provide all sorts of critical nutrients for the brain and animal fat would provide tons of calories primates figuring out how to get meat was the most obvious explanation for evolving the human brain however zoologist DrMichael Crawford thought that there was another piece to the puzzle in the 198 80s he decided to investigate what types of fat there were in the bodies and brains of various types of animals he noted that high levels of two fats helped make the brain grow and there was a third fat that seemed to be bad for brain growth the two fats that made the brain grow and therefore were very important for the evolution of the brain are arachadonic acid AA and doosa hexanoic acid DHA humans could get plenty of AA by hunting various land animals but land animals aren't that great of a source of DHA you can get a good amount of DHA from the brains and eyes of animals but early humans would have had to crack open a ton of animal skulls to get a steady supply of DH it's a little while since I've cooked sheep's brains really DH is most important during development of the braad Crawford argues that the real reason human brains evolved was because early humans found a more simple way to get the special DHA now primates like humans and monkeys have enzymes that allow them to make a very small amount of DHA from a fat in plant Foods so to get a lot of DHA you can't make it you have to eat it now the average monkey diet does not naturally contain much DHA so what happens if you give monkeys DHA a 2014 paper outlines the work of some dedicated researchers at the University of California Davis who took some Reese's monkeys and fend them a diet high in DHA for their entire lifespan about 17 to 19 years after all this time they put the monkeys in a brain scanner to see if anything was different they found that compared to the other monkeys the brains of the monkeys on the a naturally High DHA diet had highly connected and well organized neural networks which in some ways quote resembled the healthy human brain that is some aspects of their brains started to look more like a human brain this information in the wrong hands could be dangerous monkeys are already smart enough to steal tourist stuff and hold it ransom for food yes the best source of DHA is seafood fish shellfish Crustaceans algae these also have all kinds of important brain nutrients like protein vitamin A zinc choline iodine selenium vitamin B12 and so on but they would be the best source of DHA Michael Crawford says it would be so easy and safe to just walk along the coastline and gather tons of nutrient-dense food versus having to hunt land animals Professor Stephen Kain of Toronto University agrees saying a shore-based diet was essential for the evolution of human brains one study from 20120 found that breastfeeding mothers who ate more omega-3 fats like DHA tended to have babies with bigger brains specifically the frontal cortex got bigger the frontal cortex controls uniquely human things like longterm goal planning decision-making and problem solving other studies suggest shrinkage of the prefrontal cortex from a DHA deficient diet several studies have found that DHA improves attention learning memory and reduces ADHD symptoms in children of course those Geniuses of the sea dolphins and other satans are getting tons of the brain evolving DHA from a diet that is mostly raw fish you might say okay well dolphins eat tons of fish why don't they just keep getting smarter and smarter why aren't they even smarter than humans researchers say that might just be simply because smarter brains packed with more neurons use tons of energy and oxygen if the Dolphin's brains guzzles up more oxygen then they can't dive as long speaking of diving our quest for DHA Rich Seafood might explain why our noses are so weird there's this old controversial Theory called The Aquatic ape theory that says that humans evolve from an ancestor that adapted to life near bodies of water several aspects of our body seem more adapted for the water for example we don't have hair on our bodies which would make it easier to swim and we have a layer of fat under our skin unlike other primates which would help us float in water further this may have something to do with why we started walking upright monkeys can walk on two feet but they prefer not to unless they are waiting through the water now most anthropologists completely reject this aquatic ape Theory but whether we had a semi- aquatic ancestor or not humans are very good at diving the human spleen for example is larger than in other primates and it acts as a reservoir of oxygen carrying red blood cells which allows us to hold our breath for longer the Baja people near the Philippines live a sea Nomad type of Lifestyle where they spend hours a day diving for all kinds of DH Rich Seafood like shellfish shrimp crab fish octopus sea urgin and Squid and their genetics gift them with an abnormally large spleen which is thought to be why some bajou can hold their breath for over 10 minutes now another interesting aspect of humans is our protruding noses unlike monkeys flat noses human noses are better at preventing water from getting in the nasal cavity when we swim or dive most monkeys are not good swimmers but the probolus monkeys are and they happen to have these big protruding noses as of 2019 Japan is number one in the world for IQ with an IQ of 106 that's a full nine points higher than the United States IQ of 97 of course there are all kinds of different factors to IQ but Japan does have a DHA rich food culture that includes plenty of seaweed and fresh seafood they eat about twice as much fish As Americans a traditional Japanese breakfast is white rice fermented soybeans miso soup with seaweed roasted fish and more dry seaweed of course you can find all kinds of fish at Japanese supermarkets and restaurants but you can even get fish rice balls or roasted fish at a convenience store what's tricky about getting an idea of which country eats the most DHA is that DHA degrades when you heat it lucky for Japan they eat plenty of raw seafood a 2022 survey found that the second most common way people ate their fish at home in Japan was raw as Sashimi Japan also has more than twice as many sushi restaurants than fast food and pizza shops combined now there's that third fat that Michael Crawford said was important to brain size that explains why animals like rhinos are so dumb in their one ton body they have a mere 350 G brain that would be like a human having a brain the size of a walnut I wish I could think of brilliant plants like that land animals like rhinos barely get any DHA but their plant-based diet gives them plenty of linolic acid linolic acid is that third fat it can compete with DHA for incorporation into the cells that is too much linolic acid will hog up space in the cells so the DHA can't get in uh did you make this with vegetable oil oh yeah thanks but I got to watch what I eat these totally new and unnatural vegetable oils that we didn't eat for 99% of human history have tons of this linolic acid that reduces levels of DHA but DHA is critical for brain function and even the evolution of the brain you might have a big bottle of linolic acid at home like sunflower oil soybean oil corn oil grape seed oil canola oil and so on most restaurants use these seed-based oils to cook with because it's so cheap right the guide to cook in a perfect steak Touch of oil in most processed food and prepackaged food has plenty of vegetable oil fried foods are of course fried in vegetable oil mayonnaise and salad dressing is primarily just vegetable oil the average person eats these oils every single day now IQ is a little controversial and does depend on many different factors but lucky for Japan which allegedly has the highest IQ in the world they consume about half the vegetable oil of Americans was served for lunch at a high school students in Woodbridge New Jersey say that the food is inedible some high school students who are so sick of their school food they've started a protest movement against it in 1970 the law changed schools could now turn to private for-profit companies to feed their students in American schools it's common to have plenty of processed food on the menu you cut back on everything salaries supplies the food in Japan school lunches are planned out by a nutritionist and it's standard to make them fresh from scratch every day what's alarming is that Michael Crawford found that those animals with high high linolic acid and low DHA had smaller brains the animals with high DHA and low linolic acid had bigger brains he says that this state of high DHA and low linolic acid is what allows the brains to grow and evolve now as Nina tael laid out in her book The Big Fat Surprise in 1911 the soap maker Proctor and Gamble figured out that they could take seeds from cotton something that no one eats run those seeds through an industrial process and make something that looked sort of like lard a very common cooking fat at the time they launched a massive marketing campaign positioning their product as a cleaner more modern alternative to lard and by 1916 sales of their crystallized cotton seed product Crisco reached 60 million PBS various other vegetable oils like corn oil canola oil and soybean oil came on the scene and this is how we went from eating 0 gr of vegetable oil a day in 1865 to 80 g a day today that's over a pound of vegetable oils a week that's around 720 calories from oil a day vegetable oils are now a $212 billion industry as of 2022 further the dietary guidelines for Americans were introduced in 1980 and recommended we swap animal fats like butter and lard for vegetable oils it makes you wonder if this could be a factor in why the IQ increase in Americans slowed down right around 1980 the vegetable oil story just gets worse from here in 2010 researchers out of Canada were trying toig figure out why some women did not have high enough levels of DHA that is multiple studies find that babies brains and intelligence benefit from the mother's DHA supplementation which would mean that women aren't getting enough DHA in the first place but the researchers were suspicious that maybe it wasn't just that they weren't eating enough DHA but something was interfering with the DHA in the women by analyzing the blood of pregnant women they found that indeed those women eating too much linolic acid had not just lower DHA but lower levels of the brain boosting fats AA a and EPA so this also suggests that linolic acid shoves out DHA and other fats essential for brain function and development then 5 years later a 2015 study found that as expected children with mothers who got too much linolic acid experienced negative effects to brain development just one year after that in 2016 a study on over 4,000 children and their mothers found that higher linolic acid in the mothers when they were pregnant was associated with more symptoms of autism spectrum disorder when the children were 6 years old 4 years later a review article calls for more investigation into how we can protect our brains by reducing how much linolic acid we eat unfortunately for children under 9 months of age there is no infant formula on the market that does not contain vegetable oils all this doesn't mean that you don't need to worry about linolic acid and DHA after you finish growing your brain DHA is critical for healthy brain functioning in adults too no matter your age Studies have found a link between DHA and everything from irritability stress depression to memory reaction time and even aggressiveness DHA has even a protective effect on the brain in the case of head trauma and papers have Associated higher consumption of linolic acid with higher rates of depression now don't get me wrong linolic acid is not a synthetic poison like lead a very small amount of linolic acid in the diet is totally normal but the problem is we are eating clearly a very unnaturally high amount of it nowadays okay so for that free gift I was talking about I'm making a full guide on how to avoid and prevent those negative health effects of seed oils and linolic acid so check the description for a link to where you can put in your email so I can include you when I send over the guide but getting back to just how unnatural seed oils are like olives produce oil mhm and seeds generally do not produce oil so I don't know what seed oil is let's say you wanted to get oil from corn you would need 20 ears of corn just to get a single tablespoon of corn oil for 1 tbspoon of sunflower oil you need 560 sunflower seeds also what even is canola have you ever eaten a canola seed canola oil is the most common cooking oil in the world but to naturally get a single tablespoon of canola oil You' need to eat almost 70,000 canola seeds in comparison what about natural fats for example if you wanted a tablespoon of oil from sardines you'd only need about two gutted sardines or two slices of fatty tuna sushimi here's where this gets confusing we have known for decades that DHA is good for the development of baby brains which is why it's been added to infant formula evidence suggests that breastfeeding women who have higher levels of DHA have smarter babies eat the F fish okay so if linolic acid is so bad and shoves out the brain healthy DHA why does the FDA require infant formula manufacturers put a large amount of linolic acid in the formula well for one thing this whole story arguably starts with the American Heart Association the American Heart Association today recommends that for heart health we get 5 to 10% of our calories from linolic Acid per day they don't say 5 to 10% of our calories from vegetable oil that's 5 to 10% of our calories specifically from linolic Acid so to break that down canola oil for example is only 20% linolic acid so if your main source of linolic acid was canola oil then you would need to eat 1,000 calories of canola oil to hit the target set by the AHA of course no one gets all their lolic acid from vegetable oil because there's many food sources of it but this means that the ah suggests that we eat 5 to 10 times the amount of linolic acid that we ate in 1865 186 5 was before seeds were crushed into oil and widely sold for human consumption now the first heart attack was recorded in 1912 this means the AHA says that in order to protect our hearts we need to eat 5 to 10 times the amount of linolic acid that we ate when there was so little heart disease that most people didn't know it existed and there's a story that I tell in my book that because heart disease was rare until the late 1920s cardiologist was a relatively small little specialty Nina tiels lays out in her book The Big Fat Surprise that initially nobody knew about the American Heart Association because it was so small and poorly funded then they got their big break when they met the makers of the hugely popular linolic acid Rich cotton seed oil product krisco in 1948 the makers of krisco gave the AHA $ 1.
7 million as the American Heart association's own history book reads it says and overnight Millions poured into our coffers as the Proctor and Gamble man they had a dinner celebrated and handed us the check the a happened to then recommend that we swap animal fats like butter for vegetable oils in 1961 okay so going back to why infant formulas have so much linolic acid the thing is they're trying to mimic breast milk and women's breast milk does have linolic acid however the composition of the breast milk depends on the mother's diet the more linolic acid a woman eats the more ends up in her breast milk and that's important because modern women because they eat a ton of vegetable oil they get a ton of linol acid and that means that their breast milk does not look like it would 100 years ago when you eat vegetable oil the linolic acid accumulates and stays in the body the percentage of this linolic acid in people's fat cells has nearly doubled from a bit under 10% in 1960 to around 20% in 2005 so the fat profile of an average American is looking more like a rhino and less like a dolphins but 10% is even too high because by 1955 people were already eating plenty of vegetable oil so what's a normal linolic acid concentration the next thing I'm going to show you I searched for for 3 years do you know what I wanted to know what was the Omega 6 fat in anybody's atap POS who was on an ancestral diet as DrChris Kenobi discovered these specific Islanders who were eating a diet unadulterated by vegetable oils the amount of polyunsaturated linolic acid that they had was only 3. 8% that is 1 fth the amount people have in their fat tissue today now seed oils are definitely worth removing from the diet but something simple I added to my daily routine to increase my energy levels and overall health was electrolytes that's why this video sponsor element comes in I started using element over 2 years ago to keep my energy levels up while I was fasting but I quickly found that they are GameChanger when doing anything from a low carb or keto diet or just exercising going into the sauna or basically anytime I'm sweating this is because sodium and electrolytes are a big component of hydration in general so replacing the sodium and electrolyt you're losing really keeps your energy levels up staying hydrated with plenty of water and an element pack here and there is now a part of my daily routine to keep my energy and focus at a high level element tastes great and it's got no junk it's just a balanced mix of sodium potassium magnesium a bit of stevia and some flavoring there's also a raw and flavored type that's only electrolytes if you go to drink lnt.
