Eating lots of or very little of certain foods that have AGEs (like grilled or fried foods) for six weeks doesn’t seem to change how well your small blood vessels work in healthy people aged 50 to 69.

Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The claim is based on a controlled intervention study with a specific outcome measure (peripheral arterial tonometry), and the language 'no detectable effect' appropriately reflects the null finding within the study’s power and duration. It does not overgeneralize beyond the population or timeframe studied. The use of 'detectable' acknowledges measurement limits, making the claim scientifically cautious and accurate.
More Accurate Statement
“In healthy adults aged 50–69, a 6-week intervention with either a high- or low-advanced glycation end product (AGE) diet has no statistically significant effect on endothelial function as measured by peripheral arterial tonometry, indicating that short-term dietary AGE intake does not alter microvascular reactivity in this population.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
Dietary intake of advanced glycation end products did not affect endothelial function and inflammation in healthy adults in a randomized controlled trial.
Scientists gave people two different diets—one with lots of browned foods (high AGEs) and one with gently cooked foods (low AGEs)—for six weeks and checked their blood vessel function. Neither diet changed how well their blood vessels worked, so eating more or fewer AGEs for a short time doesn’t seem to affect blood vessel health in middle-aged and older adults.
