Eating carbs makes your body naturally release insulin for a short time—this is different from when doctors give insulin through an IV for a long time.
Scientific Claim
In healthy adults, ingestion of a carbohydrate meal leads to transient physiological insulin elevation (to 588±72 pmol/L), which occurs without exogenous insulin administration and is distinct from sustained insulin infusion protocols.
Original Statement
“It has been shown that sustained insulin infusion causes an increase in sympathetic vasoconstrictor discharge but, despite this, also causes peripheral vasodilatation. The present study was designed to determine... the effect of ingestion of a carbohydrate meal, with its attendant physiological insulinaemia...”

Assessment Explanation
The abstract clearly describes the insulin rise as a result of meal ingestion and contrasts it with infusion protocols. No causal language is used here, and the verb strength is appropriately conservative.
Evidence from Studies
Supporting (1)
When healthy people eat a carb-rich meal, their body naturally releases a spike of insulin—about 588 units—and this happens without any shots or IVs, just like the claim says.
