Whenever blood sugar levels cross above 140 mg/dL, arterial lining damage and vessel wall inflammation begin to occur.
"And every time blood sugar crosses over 140 mg—this is per deciliter, and this is US numbers—the lining of your arteries start to take damage. Inflammation fires up inside the vessel wall." (said at 0:44:00)
Postprandial hyperglycemia and acute glucose fluctuations do promote oxidative stress, transient endothelial dysfunction (such as impaired flow-mediated dilation), and inflammatory signaling in the vascular wall. Furthermore, 140 mg/dL is a standard clinical diagnostic cutoff for impaired glucose tolerance (2-hour postprandial glucose ≥140 mg/dL). However, framing 140 mg/dL as an absolute mechanical threshold where arterial lining damage and vessel wall inflammation instantly 'fire up' 'every time' oversimplifies a continuous, dose-dependent biological gradient. In healthy individuals, transient postprandial glucose excursions cause reversible physiological changes rather than immediate, permanent arterial damage.

"There is a linear relationship between the risk of cardiovascular death and the 2-h oral glucose tolerance test, while a study confirms postprandial hyperglycemia as independent risk factor for cardiovascular disease in type 2 diabetes. At the same time, several studies show that postprandial hypertriglyceridemia may also be a cardiovascular risk factor. Interestingly, the simultaneous presence of postprandial hyperglycemia and postprandial hypertriglyceridemia has an additive effect in worsening endothelial function and inflammation."

"Oxidative stress is increased by chronic hyperglycemia and acute glucose fluctuations induced by postprandial hyperglycemia in patients with diabetes mellitus. In addition, selective insulin resistance in the phosphoinositide 3-kinase/Akt/endothelial nitric oxide (NO) synthase pathway in endothelial cells is involved in decreased NO production and increased endothelin-1 production from the endothelium, resulting in endothelial dysfunction."

Strokes and heart attacks are vascular events primarily caused by vascular inflammation stemming from unrecognized metabolic disease.
"strokes, heart attacks, they're the same kind of thing. They're both events that happen from vascular inflammation, most often from inflammation caused by unrecognized metabolic disease." (said at 1:01:53)
While vascular inflammation is an established mechanistic driver in the development and rupture of atherosclerotic plaques, asserting that heart attacks and strokes are 'most often' caused by inflammation from unrecognized metabolic disease overstates the epidemiological evidence. Large-scale international studies (INTERHEART and INTERSTROKE) demonstrate that acute myocardial infarction and stroke are multifactorial conditions driven primarily by a combination of modifiable risk factors. For myocardial infarction, abnormal lipid ratios (ApoB/ApoA1, population attributable risk [PAR] 49.2%), smoking (PAR 35.7%), and hypertension are leading contributors alongside abdominal obesity and diabetes. For stroke, hypertension is by far the single largest contributor (PAR 47.9%), followed by physical inactivity, dyslipidemia, and cardioembolic sources (such as atrial fibrillation), with roughly 10–15% of strokes being hemorrhagic rather than atherothrombotic.
