Recent social media trends highlighting "old people smell" and "Ozempic smell" have prompted discussion on how diet affects body odor. Experts explain that various foods, including fish, cruciferous vegetables, spicy foods, and red meat, can impact scent due to interactions with skin bacteria. Conditions like trimethylaminuria can amplify fishy odors. However, mitigating unpleasant smells is possible through dietary changes, such as reducing sulfur-rich foods and red meat, increasing water and healthy foods, and maintaining good hygiene.
