The Claim

Maillard reaction products formed during high-heat cooking inhibit α-glucosidase and other amylolytic enzymes, resulting in reduced starch digestibility and altered postprandial glucose metabolism.

How it works
1 study reviewed
In plain English

Cooking food at high temperatures produces chemical compounds that slow down the breakdown of starch in the digestive system, leading to lower rates of glucose release after eating.

See the scientific wording

Maillard reaction products formed during high-heat cooking reduce starch digestibility by inhibiting α-glucosidase and other amylolytic enzymes, as demonstrated in vitro using glucose-glycine mixtures heated at 90°C for up to 48 hours, which led to significant reductions in starch hydrolysis rates compared to unheated controls, suggesting that cooking methods influencing browning may alter postprandial glucose metabolism.

Why this might work

When food is cooked at high temperatures, sugars and proteins react to form compounds that block enzymes that break down starch, slowing glucose release into the blood. These same compounds reach the gut unchanged and feed bacteria that produce beneficial fats, while reducing bacteria that cause harm.

  1. Study: Influence of Nonenzymatic Browning Reactions on the Digestibility and Gut Microbiota Fermentation of Starch and Protein

    When food gets browned during cooking, chemical changes create substances that slow down the enzymes that break down starch, making carbs digest more slowly — which could help control blood sugar spikes.
