After a rice-free sashimi dinner or an all-you-can-eat Brazilian barbecue
, your body is tasked with metabolizing a high amount of protein
. This produces a by-product of ammonia, which, among other places in the body, is released in your breath (fortunately, your dining companions will suffer the same condition). Eating this way on a regular basis—by following a high-protein diet, for example— requires your body to constantly excrete these by-products, as well as molecules called ketones, which can cause your breath to smell in a way that’s described as rotten fruit
—or just rotten.
