9. Coffee and Alcohol
Tied at number two for stick causing foods are coffee and alcohol. Everyone is familiar with coffee breath and many alcohols are immediately obvious in close quarters.
Basically, both beverages dry out your mouth by reducing saliva flow. That allow bacteria that cause bad breath to flourish.
Alcohol causes body odor as it metabolizes. As you body breaks down alcohol, it becomes acetaldehyde. As you sweat, the smell pours out your pores. Try not to drink heavily the night before you really want to smell good!
