Not at all productive. They got stuck on the saturated fat healthy or unhealthy chapter. Kresser seemed very well prepared and knew exactly how to install doubt in the viewer's mind.
I listened to snippets of the debate.
I know next to nothing about this topic, save that nutrition research is highly complex and often conflicting.
Kresser brought up some good points, but misrepresenting a handful of cherry-picked egg studies does not invalidate 50+ years of cholesterol research.
Isn’t there something of a consensus on saturated fat in nutrition science? Health organizations typically advise people to eat as little saturated fat as possible, warning that eating foods high in cholesterol could result in increased LDL and increased risk of heart disease.
American Heart Association wrote:Eating foods that contain saturated fats raises the level of cholesterol in your blood. High levels of LDL cholesterol in your blood increase your risk of heart disease and stroke… Replacing foods that are high in saturated fat with healthier options can lower blood cholesterol levels and improve lipid profiles.

Other health organizations echo this sentiment.
World Health Organization wrote: Also, the risk of developing NCDs is lowered by reducing saturated fats to less than 10% of total energy intake, and trans fats to less than 1% of total energy intake, and replacing both with unsaturated fats, in particular with polyunsaturated fats…Unsaturated fats (found in fish, avocado, nuts, sunflower, canola and olive oils) are preferable to saturated fats (found in fatty meat, butter, palm and coconut oil, cream, cheese, ghee and lard) and trans-fats of all kinds…

Kresser also seems adamant about a lack of evidence that high blood cholesterol increases the risk of heart attack. But a lack of evidence is
not evidence that saturated fat is healthy, especially since research shows that
unsaturated fats (relative to saturated fats) promote heart health.
Heart Foundation wrote:The combined evidence suggests that whole diet changes, not altering one nutrient, is required
to promote cardiovascular health. Replacing
energy intake from saturated fat with energy from polyunsaturated fat (PUFA),8 monounsaturated fat (MUFA) and wholegrains is associated with a lower risk of a heart disease.
The rational thing would be to follow the guidelines of health professionals, who are properly trained to conduct and extrapolate on hard science. Their general advice is to limit foods high in saturated fats, and eat plenty of foods high in poly and monounsaturated fats.
Also, as you stated, I find it interesting that Kresser is rather skeptical of old studies, but cites a 1999 study on egg consumption and risk of cardiovascular disease to prove that dietary cholesterol doesn't raise blood cholesterol (anyone familiar with nutrition here who can engage those claims?)
I think Kresser is a good example of why we should rely on nutritionists and professional guidelines instead of our own myopic biases and limited research.
