Anything can become deadly if you eat enough of it. Sometimes it just takes a really long time. Check out this list of nine foods and drugs, and the lethal doses for a 150-pound person, when eaten in a single sitting.
1. 40 cigarettes. It might not be obvious, but the nicotine is what would actually kill you.
2. 37-and-a-half tubes of toothpaste. You'd die from the fluoride.
3. 5.1 pounds of spinach. You'd end up overdosing on oxalic acid.
4. 1.4 gallons of water.
5. 1.8 COWS' worth of beef. Believe it or not, the IRON would finish you off.
6. 18 shots of vodka.
7. 48 cups of coffee. The caffeine would be the lethal ingredient.
8. 122,448 pieces of tuna sushi. That much would give you a lethal dose of mercury.
9. A single polar bear liver. The stored vitamin A would kill you.
