Yes or no? Do you believe nicotine is not  addictive? I believe nicotine is not addictive,  
[5]
yes. Mr. Johnson? Uh, congressman, cigarettes  and nicotine clearly do not meet the classic  
[13]
definitions of addiction, there is no  intoxication. We’ll take that as a no  
[16]
and again time is short, if you could just,  I think each of you believe nicotine is not  
[20]
addictive. We just would like to have this for  the record. I don’t believe that nicotine or our  
[24]
products are addictive. I believe nicotine  is not addictive. I believe that nicotine  
[30]
is not addictive. I believe that nicotine  is not addictive. And I too believe that  
[63]
nicotine is not addictive.

The SRF’s purpose, and I quote “was dedicated  to the scientific study of sugar’s role in food  
[84]
and communication of that role to the public  during a period of war-time sugar rationing.”  
[90]
But as we already know, bureaucracy is a  machine that keeps growing exponentially.
[95]
By the end of World War II , 77 firms and  corporations, presumably led by the global elite,  
[103]
were actively involved in the SRF. While The  foundation funded some scientific research,  
[108]
their mission statement was and still  is “to convey the value of sugar as  
[113]
a food staple and industry to the public  using accurate and pertinent information”
[118]
These were going to be completely unbiased,  rigorously reviewed, pieces of evidence,  
[123]
right? It doesn’t take a rocket scientist to  see that there would be conflicts of interest  
[128]
in the research of the products they sell.  These conflicts of interest came to light  
[133]
in 2016, but it was too late as sugar had  already become a staple in modern food.  
[138]
The Journal of the American Medical Association,  one of the top sources of scientific literature,  
[144]
got its hands on internal industry documents  from the SRF, including corporate conversations  
[151]
and instructions that the foundation gave the  scientists it worked with. They also looked at  
[157]
the evidence that was used to create the dietary  recommendations of several government health  
[162]
organizations *show pics of organizations from  study*. Three researchers used the documents to  
[166]
tell us a chronological story of special interest  corruption on behalf of the SRF. The paper made  
[172]
very few headlines, so most people have no idea  about it. Therefore, I’m going to summarize the  
[178]
findings from the paper, which you can  find linked in the description below.  
[183]
The story begins in the 1950s. Coronary heart  disease was at an all-time high, and scientists  
[194]
began researching dietary factors for possible  causes. By the 1960s, two major camps evolved  
[203]
that argued the main cause of heart disease. One  hypothesis was built on the work of prominent  
[208]
British physiologist John Yudkin, who claimed that  added sugar was the culprit. On the other hand,  
[214]
an American physiologist named Ancel Keys,  claimed that total and saturated fat were the  
[220]
main causes. One of these two theories would end  up shaping nutrition science as we know it today.
[226]
Clearly the SRF needed to protect the interests  of their shareholders. The SRF’s president,  
[234]
Henry Hass, closely observed the debate. He  gave a speech in 1954 to the American Society  
[241]
of Sugar Beet Technologists, saying “Leading  nutritionists are pointing out the chemical  
[247]
connection between [American’s] high-fat  diet and the formation of cholesterol… If  
[251]
the carbohydrate industries were to recapture  this 20 percent of the calories in the US diet…  
[257]
this change would mean an increase in the  per capita consumption of sugar more than  
[262]
a third.” [pull up study quote and highlight] The sugar industry’s goal was to replace the  
[266]
market share of fat with sugar. So they decided to  invest $600,000, which is $5.3 million in today’s  
[275]
money, to increase their profits. ATP Science  on Youtube does a great job explaining what  
[282]
happened. They paid $5.3 million to educate policy  makers, which are basically politicians with no  
[290]
scientific background, educate policy makers on  how fat causes heart disease by basically saying  
[296]
look inside this artery, it's got fat in it.  Look in this food, it’s fat. There’s no sugar  
[301]
inside this artery. Sugar can’t go inside the  artery, fat goes in the artery, therefore fat  
[305]
is evil and sugar’s good. And the policy makers–  “makes sense to me, I have no idea about science.”  
[309]
And with the $5.3 million investment into the  propaganda, they managed to get the policy and  
[315]
what their whole campaign was, was to stimulate  the business associated with the profit of selling  
[320]
sugar by taking 20% of the allocated calories in  the food pyramid off the fat to give to sugar.
[326]
Profits continued to rise for the  sugar industry as people started to  
[331]
eat less and less fat. Everything was  going smoothly until new research came  
[336]
out stating that low fat diets high in sugar  could raise serum cholesterol. John Hickson,  
[342]
the Vice President of the SRF at the time, began  keeping his eye on this new information. He  
[348]
considered multiple ways to combat the so-called  deniers, such as the physiologist Yudkin.  
[353]
In 1965, the SRF decided to appoint a new  member to its scientific advisory board.  
[360]
This new member was Fredrick Stare, chair of the  School of Public Health Nutrition Department of  
[367]
Harvard University. He was an expert on dietary  causes of heart disease, and was also consulted  
[374]
by the American Heart Association and National  Heart Institute. However, he also had ties to  
[381]
food companies and trade groups, which  weren’t widely questioned until the 70s.
[386]
Later on in 1965, a faculty member of Stare’s  department at Harvard, D. Mark Hegsted,  
[393]
published three contradictory studies. The  first two were epidemiological studies that  
[400]
suggested blood sugar to be a better predictor  of atherosclerosis than serum cholesterol. The  
[407]
third study showed that sugar, more than  other carbohydrates, contributed to high  
[412]
triglycerides. Yudkin previously claimed that  this was a major risk factor for Heart Disease.  
[418]
The New York Herald Tribune jumped on board,  running an article supporting the notion that  
[424]
sugar consumption may be casual in developing  heart disease. As Yudkin’s hypothesis on the  
[431]
true cause of heart disease gained validation  through Hegsted’s research, the SRF had to act  
[436]
quickly to protect their financial interests. That’s exactly what they did. Two days after the  
[442]
article was published, the SRF approved of  project 226. Project 226 was designated as  
[450]
a literature review of “Carbohydrates and  Cholesterol Metabolism.” The project was  
[456]
overseen by Stare and written by Hegsted  and colleague at Harvard, Robert McGandy.
[461]
Hickson provided the researchers with  articles demonizing sucrose, which is sugar,  
[467]
that could’ve potentially threatened his profits.  Hickson told Hegsted “Our particular interest had  
[474]
to do with that part of nutrition in which there  are claims that carbohydrates in the form of  
[479]
sucrose make an inordinate contribution  to the metabolic condition, [until now,  
[484]
the consensus has been that fat intake is the  cause]. I will be disappointed if this aspect is  
[490]
drowned out in a cascade of review and general  interpretation.” Hegsted replied “We are well  
[497]
aware of your particular interest in carbohydrate  and will cover this as well as we can.”
[502]
As you can see, Hickson really had a way with  words. He converted a man who conducted three  
[508]
studies correlating sugar with heart disease,  to a believer of the dietary fat hypothesis in  
[513]
just a few sentences. Or maybe it was the $6500,  which would be about 50 grand in today’s money,  
[520]
that Hickson ended up paying him. Either  way, Hickson was one convincing guy.
[525]
As Hegsted and McGandy worked on project  226, a separate group of researchers,  
[531]
known as the Iowa Group, were reporting  that there were positive associations  
[536]
between the consumption of  sugar and serum cholesterol.
[538]
In the 9th month of the project, Hegsted  explained to the SRF that “Every time the  
[545]
Iowa group publishes a paper we have  to rework a section in rebuttal.”  
[549]
Hegsted gave Hickson the final draft  about half a year later and Hickson  
[554]
assured him “This is quite what we  had in mind and we look forward to  
[558]
its appearance in print.” The literature  was published in the New England Journal  
[563]
of Medicine in 1967 titled “Dietary Fats,  Carbohydrates, and Atherosclerotic Disease.”
[570]
As with any respectable piece of scientific  literature, those who funded the study were  
[577]
cited in the paper for the public to see. However,  Hickson’s payment to Hegsted was not disclosed,  
[583]
but that’s probably because Hegsted pocketed  the cash instead of using it for the research.  
[587]
The paper assured that the only way to prevent  heart disease was to reduce dietary cholesterol,  
[594]
and to replace saturated fats  with polyunsaturated fats.  
[598]
Any objective view seems to indicate that the  SRF retained their own scientific hired guns to  
[605]
manipulate the empirical data and reach their  pre-determined results. They put out enough  
[611]
information to influence government policy,  exactly what the sugar industries needed.
[616]
The review contained epidemiological,  
[619]
experimental, and mechanistic studies  of sugar’s effect on coronary heart  
[623]
disease. The epidemiological studies done  by Yudkin and the Iowa group showed that  
[628]
there was a positive association with the  consumption of sucrose and heart disease.
[632]
Of course, those studies were discounted  either because of confounding variables,  
[637]
poor interpretation or the  method of collection of the data.
[642]
The experimental studies showed that serum  cholesterol and triglycerides rose when components  
[649]
of the diet like fat, starch and vegetables  were replaced with sugar. But apparently,  
[655]
the amount of sucrose used in the studies  supposedly wasn’t comparable to American diets,  
[660]
so that was disregarded by Hegsed and  company as well. They also believed  
[665]
that the studies showing a raise  in triglycerides were irrelevant  
[669]
because total blood cholesterol was  the real risk factor for heart disease.
[673]
PSH! I don't know about that
[677]
Then finally, the mechanistic studies showed  that it was biologically plausible that sucrose  
[682]
could affect cholesterol levels and fructose  could affect triglyceride levels. However,  
[687]
this hypothesis was ultimately disregarded  because it was built on mechanistic evidence  
[692]
conducted with glucose and fructose  instead of sucrose. Never mind that  
[697]
the sucrose molecule immediately breaks down  into glucose and fructose upon digestion.
[702]
Also, never mind that the epidemiology, controlled  trials, and mechanistic data all painted a clear  
[711]
picture on sugar’s role in heart disease. They  also fed rats low fat high carb diets that would  
[717]
supposedly never be in line with a human’s, even  though that’s essentially what they recommended.
[722]
So the review looked at the overwhelming  body of evidence that sugar had a clear  
[727]
role in the development of heart disease,  but went ahead and picked each study apart  
[732]
one by one to deny the obvious conclusion.  In essence they’re just making stuff up.
[739]
Okay? Alright...
[740]
So the SRF funded review, utilized hired  guns and dismissed all of the studies  
[747]
showing sucrose to be harmful, but did not  include any quantitative results detailing  
[753]
fat’s intervention in the studies. Of  course, they overstated the effect that  
[758]
fat had in the studies. There was only one  randomized control trial that lowered serum  
[764]
cholesterol by substituting saturated fat  for polyunsaturated fat. Out of all the  
[770]
studies they reviewed though, this was the only  relevant experiment to draw a conclusion with.
[775]
Would you just look at it? I mean just look at it
[780]
Even though the epidemiology was ignored with  the sugar studies, the epidemiology from the  
[784]
fat studies was extremely important. They  could draw the conclusion that fat causes  
[789]
heart disease from those. The review made sure to  claim that polyunsaturated fats were a realistic  
[796]
replacement for saturated fats, and that  it was the only dietary change that people  
[801]
should make in order to avoid heart disease. It’s clear that the SRF engaged in coronary  
[808]
heart disease research in 1965, and then funded  and participated in a literature review published  
[814]
in the New England Journal of Medicine. Their role  in the review wasn’t disclosed until 2016. The New  
[822]
England Journal of Medicine did exactly what the  sugar industry wanted them to do and told society  
[827]
to ignore the epidemiological, experimental, and  mechanistic studies linking sucrose to coronary  
[833]
heart disease. They told people that the only  thing they had to worry about for heart health was  
[839]
dietary cholesterol and saturated fat. Americans  had been convinced that they had nothing to worry  
[845]
about when it came to sugar, and that they should  just avoid fat and they will be fine. So called  
[851]
healthier low fat alternatives started flooding  the market, with sugar replacing the fat.  
[857]
The story doesn’t end there though. In  1971, the sugar industry got into the  
[866]
minds and pockets of the National Institute  of Dental Research Caries Program. They aimed  
[872]
to shift the focus of dental problems away  from the consumption of sucrose. In 1976,  
[880]
the sugar industry came out with another review  called “Sugar in the Diet of Man.” It’s credited  
[886]
with strongly influencing the evaluation  of the safety of sugar by the FDA in 1976.  
[893]
By the 1980s, most scientists believed  that added sugar had nothing to do with  
[899]
coronary heart disease. The SRF got exactly  what they wanted, and the money poured in.
[905]
In essence, whether you know it or not, the  sugar industry is a giant money machine.  
[911]
They have had and still have a pivotal role  in influencing American dietary policies.  
[918]
Policy makers and average citizens don’t read  scientific journals, so they will blindly follow  
[924]
the recommendations the USDA gives them. This is  why it’s so important to regulate conflicts of  
[930]
interest in dietary studies. Some bad information  could lead to years of bad policy. Much of the  
[939]
information propagated by the SRF is still  very relevant in mainstream science today.
[944]
With access to insider industry documents  like these, we the people have a chance to  
[951]
search for the truth. The SRF paid scientists  to come up with enough paperwork to show that  
[958]
sugar is nothing to be concerned about,  all to increase their market share.  
[962]
The tobacco industry used similar tactics.  They convinced us that smoking was healthy,  
[969]
but thankfully, the public perception changed.  Now, even smokers acknowledge that smoking is  
[976]
unhealthy. However, the public perception of sugar  still hasn’t changed, with most people believing  
[983]
that it’s fine to consume in moderation. The  sugar industry was more successful in deceiving  
[989]
the public than the tobacco industry  because the public still believes them.
[993]
John Yudkin had worked diligently to  research the harmful effects of sugar,  
[999]
and let the world know before it  became a staple in nearly every  
[1003]
food in the market. But as they say,  history is decided by the winners.
[1009]
The SRF is now known as the Sugar Association,  
[1013]
and it still has a powerful hand in Washington  DC. It still strongly denies the possibility  
[1020]
that there is a relationship between sugar  consumption and cardiovascular disease.
[1025]
The sugar industry had a huge  role in shaping over 50 years  
[1031]
of nutritional science and the dietary  recommendations that we still have today.
