Consumption of meat and meat-products, particularly those high in heme iron and polyunsaturated fatty acids, induces oxidative stress through the generation of reactive aldehydes (MDA, 4-HNE) and advanced glycation end-products (AGEs) during digestion and metabolism.

To minimize oxidative stress from meat, prioritize meats with lower heme iron and PUFA content where possible, and be aware that processing, cooking, and storage methods significantly increase the formation of oxidation compounds like MDA and 4-HNE. Pairing meat with antioxidant-rich plant foods may help mitigate some oxidative damage, though the paper emphasizes the need for personalized nutrition based on genetic susceptibility.

The gastrointestinal tract is the gateway for oxidized food compounds produced during processing and storage of meat, but they can also originate during digestion and metabolization... The available literature indicates that a part of the diet oxidation compounds is absorbed in the lymph or directly into the bloodstream, being able to induce oxidative damage in biological systems [14,15].
