Ah, food. There aren't many things on which the people of the world agree, but our love of food is one of them. This Mental Floss video selects common bits of misinformation often heard about food, its additives, shelf life, preparation, cooking methods and more. One food mentioned that I can foresee never being under a false impression about is chocolate. I have that one down cold!
That pasta will cook faster in salted water is a misconception, but salt should still be used in tastable amounts because it will noticeably improve the flavor of the pasta. 2% salinity is ideal, which is way beyond what dudeman here mockingly refers too as "way too much". Thomas Keller recommends the water you boil in should be "as salty and voluminous as the ocean" - high volume helps the temperature not drop substantially when handfuls of room temp pasta are dropped into the water.
