When you grill, fry, or bake food at high heat, harmful compounds called AGEs form—but you can reduce them by steaming, boiling, marinating with vinegar or lemon, or adding things like green tea extract or beet juice.

Assessment Explanation
The claim describes biochemical mechanisms (Maillard reaction, lipid oxidation) and multiple modifiable factors (cooking methods, marinades, antioxidants) that have been demonstrated in in vitro and animal studies to influence AGE formation. Human studies show associations, but not all interventions are equally validated. The use of 'reduced by' is reasonable as a probabilistic statement given consistent trends across studies, but not definitive for all contexts. The claim avoids absolute language and acknowledges multiple pathways, making it scientifically sound.
More Accurate Statement
“Advanced glycation end-products (AGEs) are likely formed in foods during high-heat, low-moisture cooking via the Maillard reaction and lipid oxidation, and their levels are generally reduced by steaming, boiling, acidic marinades, or the addition of natural antioxidants such as epigallocatechin gallate or betanin.”

Exploring Formation and Control of Hazards in Thermal Processing for Food Safety
This study says that cooking food at high heat (like frying or baking) makes harmful substances called AGEs, but using gentler methods like steaming or adding things like green tea extract can help reduce them — which matches exactly what the claim says.
