A 16-week low-fat plant-based diet lowered dietary AGEs from about 11,100 to 2,300 kU/day in adults with overweight.
Evidence for a vegan diet
A low-fat vegan diet can sharply reduce dAGE exposure.
The practical reason is simple: the highest dAGE loads tend to come from animal-derived, high-fat, high-protein foods cooked with dry heat. A low-fat vegan pattern shifts meals toward legumes, grains, fruits, and vegetables and away from the major sources measured in AGE food tables.
In a randomized crossover trial, dietary AGEs fell on the low-fat vegan phase and did not significantly change on the Mediterranean phase.
A 12-week type 1 diabetes trial abstract reported a large dAGE drop on a low-fat vegan diet versus portion control.
Why it works
Diet pattern plus cooking method.
A vegan diet is useful for lowering dietary AGE load because it changes the ingredient pool before cooking even starts. In the 2024 randomized crossover trial, the low-fat vegan phase cut dietary AGEs by 9,413 kU/day, while the Mediterranean phase showed no significant reduction. The authors attributed most of the decrease to excluding meat and to reducing added fats and dairy.
The 2023 randomized clinical trial found a similar pattern: dAGEs dropped on a low-fat plant-based diet and the change tracked with improvements in body weight, fat mass, visceral fat, and insulin sensitivity. These studies support the idea that lowering dAGEs can be achieved through dietary composition, not only by changing how the same foods are cooked.
Animal-derived foods that are high in fat and protein tend to start with higher AGE values and form more AGEs during dry, high-temperature cooking.
A low-fat vegan pattern removes meat, dairy, and eggs, while emphasizing foods that are usually lower in measured dAGEs: legumes, grains, vegetables, fruit, and low-fat plant foods.
Cooking technique still matters. Moist heat, lower temperatures, shorter cooking times, and acidic ingredients can lower dAGE formation even within the same food category.
Practical use
Build lower-dAGE meals.
- Swap grilled chicken, steak, bacon, or fried eggs for beans, lentils, tofu, tempeh, or vegetable-forward meals.
- Choose boiled, steamed, stewed, or pressure-cooked preparations more often than grilled, broiled, roasted, or fried foods.
- Limit added oils and high-fat processed foods when the goal is specifically to reduce dAGE exposure.

Available data consistently point in the same practical direction: lower-fat vegan dietary patterns can substantially reduce estimated dAGE exposure, especially when they replace meat, high-fat animal foods, and added fats with legumes, grains, fruits, vegetables, and gentler cooking methods.
