Foods Containing Sulfur
Plants that are in the Brassica genus, including broccoli, cabbage and cauliflower, can affect body odor because of the vegetables’ sulfur compounds. So can foods in the Allium genus, which include onions and garlic, also due to their sulfur compounds. To see how pungent these compounds can be, try this experiment: rub crushed raw garlic on the sole of your foot—within about 20 minutes you’re likely to taste it in your mouth. If you like garlic but not the mouth odor, try drinking milk after eating it. A 2010 study in the Journal of Food Science found this may help.
