Eating vitamin C-rich foods with unprocessed red meat substantially mitigates the formation of harmful compounds in the human gut.
"What we know about unprocessed red meat is that those compounds don't get formed to the same degree when you eat that food and eating unprocessed red meat like a burger with some lettuce, a tomato, some fruit, anything with vitamin C can substantially mitigate the formation of any of the harmful compounds in your gut."

While vitamin C (ascorbic acid) can inhibit acid-catalyzed nitrosation in the stomach from dietary nitrite, human intervention studies examining red meat-induced endogenous nitrosation in the gut show that vitamin C does not substantially mitigate the intestinal formation of apparent total N-nitroso compounds (ATNC). In a randomized crossover dietary trial in ileostomy patients fed diets containing red meat, supplementation with 1 g of ascorbic acid had no effect on ATNC concentrations in intestinal output, because haem-driven nitrosation in the gastrointestinal tract operates through mechanisms distinct from standard acid-catalyzed nitrosation.
In the United States, per capita beef consumption peaked at 92 pounds per year in 1976 and fell to under 60 pounds per year by the late 2010s, while rates of heart disease, diabetes, obesity, and Alzheimer's disease increased during the same period.
"In the 1970s, Americans ate over 90 lb of beef per person per year. This actually peaked in 1976 with 92 lb of beef per person per year. By the late 2010s, this number had fallen to less than 60 lb per year, probably driven by the anti-meat propaganda that is rampant in our news cycle. But during that same period, heart disease, diabetes, obesity, and Alzheimer's dementia, all diseases that red meat has been blamed for, actually went up." (said at 0:09:45)
The speaker bundles multiple claims regarding historical trends from the 1970s to the 2010s. While USDA historical data shows US per capita beef consumption did peak in 1976 (at over 90 pounds per year) and declined to under 60 pounds by the late 2010s, and rates of obesity, diabetes, and diagnosed Alzheimer's disease rose significantly during this period, the assertion that rates of heart disease increased is contradicted by epidemiological data. Long-term surveillance data from the National Vital Statistics System demonstrate that age-adjusted heart disease mortality in the United States declined by approximately 66% between 1970 and 2022 (from 761 to 258 per 100,000), driven primarily by an 81% decline in ischemic heart disease and an 89% decline in acute myocardial infarction mortality.
