I think he's three orders of magnitude off on his energy calculations, but I CBA to do the math to check.

A Food calorie is actually a thousand Energy calories (sometimes they label them properly on packages as kcal). One small calorie is enough to heat 1 gram of water 1 degree, or about 4.2 joules. One food calorie (kcal, kilocalorie, large calorie) is enough to heat a kilogram of water 1 degree, or about 4200 joules.

On an episode of Bang Goes The Theory (a science show in the UK) they blow a hole in a sheet of steel with an explosion made with the contents of a minibox of cereal. Its truly fascinating how much energy is contained in a small amount of food.

Here's a clip of it. Jem's explosive breakfast - snap, crackle, bang! - Bang Goes the Theory - BBC One Picture that explosion times a trillion.
