However, it is consistent with other studies, so it warrants further study to better understand the biological mechanisms. Public health implications The researchers acknowledged study limitations, including the potential for confounding in observational studies and the fact that several cancer types in the analysis had low event rates, leading to wide confidence intervals and limiting statistical power

Foods Rich in Glutathione Precursors Since cysteine availability is the rate-limiting factor for glutathione synthesis, foods rich in cysteine and sulfur-containing amino acids are particularly important [2][9]: High-cysteine protein sources: Whey protein, eggs, chicken, turkey, pork, beef, fish Sulfur-rich vegetables (also activate Nrf2): Broccoli, Brussels sprouts, cauliflower, kale, cabbage, garlic, onions, shallots Glycine-rich foods (collagen sources): Bone broth, gelatin, skin-on chicken, pork rinds Glutamic acid sources: Tomatoes, mushrooms, parmesan cheese, soy sauce, fermented foods Practical Notes Cooking reduces glutathione: Raw fruits and vegetables contain more glutathione than cooked versions
