“Well, most people don't understand that the sugar industry's hijacking of science in the 1950s, the way they paid off those scientists to literally false adver…”
Speaker claims the sugar industry paid scientists in the 1950s to falsely blame saturated fat/cholesterol for heart disease instead of sugar.
“If you look at red meat consumption in the U.S. since about 1977, so red meat has gone down about 30% to 40%. Really? Yeah. We used to eat way more in the 70s.…”

“Hong Kong right now, if you look up, if you Google Hong Kong life expectancy, they live the longest out of anybody in the world, right? They eat about 40% more…”
Baker claims Hong Kong has the world's longest life expectancy and that its residents eat about 40% more red meat than Americans, implying red meat consumption explains their longevity.
“They looked at people with chronic constipation. They were always constipated and the only thing that helped them was taking all fiber out of their diet.”

“there was, you know, the World Health Organization two years ago, last year, two years ago, declared that red meat was a class two carcinogen and processed mea…”
Baker states the WHO/IARC classified red meat as a class 2 carcinogen and processed meat as class 1, then frames this classification as based on weak epidemiology and questionable rat studies.
“There's some health organization in UK that did a press release and said that the average five-year-old consumes 50 grams of sugar a day”
Patrick claims a UK health organization reported that the average five-year-old consumes 50 grams of sugar per day, then muddles whether this figure is daily or equal to a year's worth matching body weight.
“there was a study that was recently published men that had like atherosclerosis, they were given 2.4 grams of garlic a day. And it actually slowed the accumula…”

“So five-year increase in life expectancy, like that's huge compared to people like, you know, on the low end of the range.”
Patrick claims a Framingham study found people with a high omega-3 index have a life expectancy five years longer than those with a low omega-3 index.
“they were 17% less likely to die prematurely of all causes, including accidents”
A cohort study of omega-3 index found people in the high range (>7%) were 17% more likely to die prematurely from all causes, including accidents, compared to the low range (<4%) -- as described, this appears to have the direction reversed.
“If meat caused cancer, most people would have cancer. 95 plus percent of the population on earth eats meat.”
Baker argues that because most people eat meat and most people don't get cancer, meat cannot cause cancer.
“by the time they're eight years old the average eight-year-old has eaten more sugar than somebody would have eaten in their entire life you know and?”
Baker claims the average 8-year-old today has consumed more sugar than a person would have eaten in an entire lifetime around 150 years ago.
“The results in the ultra-processed DGA menu that was created, 91% of the kilocalories were from ultra-processed food or NOVA Category 4.”
Baker cites a study claiming a menu built to meet U.S. Dietary Guidelines can be 91% ultra-processed food by calories and still score as healthy.
“You know, 80% of medical schools in the United States don't require a single nutrition course. Not one minute of nutrition. And yet 90% of our healthcare costs…”
Casey Means claims 80 percent of US medical schools do not require a single nutrition course while 90 percent of healthcare costs are tied to disease.
“A cigarette will consume 75 milligrams of vitamin C, and they tell you that you only need 190 milligrams a day. That's the FDA requirement.”

“And, oh, yeah, just before she debated, a study was released that was published by Harvard epidemiologists. I think they were epidemiologists. They did a retro…”
