10 Food Myths Debunked

Katie Johnson

Soda rots your teeth. Literally?

Vaughan: "Sodas are highly acidic and high in phosphates, both of which can erode tooth enamel over time. Some food additives used can also increase tooth enamel breakdown. These harmful effects are seen in regular and diet sodas. Regular sodas have the problem of added sugar (which feeds bacteria in your mouth, forming even more acid). What to do? Limit intake of soda, use a straw when you do drink soda, rinse your mouth with water after drinking soda."

It's impossible to drink an entire gallon of milk.

Vaughan: "Stomach capacity for most adults is about one liter but maximum capacity (be warned: there is a lot of discomfort when someone reaches max capacity!) can be as much as 2-4 liters depending upon body size.

One gallon = 3.8 liters so most people would have a very, very hard time drinking an entire gallon of milk at one time. Most people would start to vomit before reaching the bottom of the gallon bottle."

If you swallow gum, it will stay in your system...for years.

Vaughan: "No, the gum is either excreted in feces/stool or gut bacteria ferment the components in the gum that our human digestive enzymes have not already digested."
