Final answer:
Fish oil can potentially change body odor as it contains odor-causing compounds, but good hygiene practices like daily bathing can minimize its effects. The fish odor can also be reduced by using acids like lemon juice or vinegar, which neutralize odor-causing compounds in the fish itself.
Step-by-step explanation:
The question 'Does fish oil change body odor?' pertains to how consumption of certain supplements like fish oil may affect our natural body scent. Body odor primarily arises due to bacteria on the skin breaking down sweat, oil, and other substances, which may include components derived from our diet.
Notably, fish oil contains compounds that can produce a distinctive smell, which can influence a person's body odor; however, if you maintain good hygiene, such as taking a daily bath or shower, this can help minimize any potential changes to body odor.
Moreover, it's important to consider that while eating fish, people often use lemon juice or vinegar, which contain acids that can neutralize volatile amines in the fish, thus reducing the fish odor and complementing its taste with a "sour" flavor we find pleasant.
