食物研究(A research on the smell of poops)。
Your smell is what you eat. 你吃了哪些種類的食物，便會使得排泄物偏向什麼樣的氣味。
‘Korean food is the tastiest but makes the smelliest poops.
English food is pretty much the same in both directions.
South Indian food is so spicy it burns on the way out, but it’s worth it.
Oklahoma BBQ takes its time and sits heavy in your belly for more than a day.
Oklahoma Tex-Mex is some of the best food in the world, but the poops are soupy.
Italy has a great taste-to-poop ratio, which is probably why so many people like it best.
…
Persian food is the perfect balance of tastiness and on-time firm poops.’
這是一位移居美國的伊朗人，總結各種不同地區的食物，對排泄物氣味的影響。
一般而言，肉類和豆類吃得比較多的人，腸胃道在消化過程中會產生較多的氨或硫化氫，這就是排泄物聞起來偏酸臭的原因。硫磺泉的臭味，就是硫化氫呢！而吃得比較清淡的人，排便比較不酸臭，是可以預期的。
評價最高的是地中海的義式食物，相對於食物的美味，排便的氣味就不算什麼。
那位伊朗人沒有提到Chinese food。或許Korean food 是一個類似的對照，對他而言，那種食物的味道最好，而排便的氣味也是最重的。
最諷刺的是英式的食物，說有多難吃排便就有多難聞，對於必須吃英式食物的人而言，真是情何以堪。
