Corn here means sweet corn (sweetcorn in the UK and Australia), the yellow kernels eaten as corn on the cob or loose. Raw kernels provide 86 kcal (360 kJ) per 100 g, mostly from starch and natural sugars, with about 3.3 g of protein. Sweet corn is starchier than most vegetables, which makes it more energy-dense than most vegetables, though it still contributes fibre and folate.

| 1 medium ear (corn on the cob) | 102 | 88 | 367 | 3.3 | 19.1 | 1.4 |

Things worth knowing
- The kernels from one medium ear of corn on the cob (about 102 g edible) have about 88 kcal / 367 kJ; a large ear (143 g of kernels) is about 123 kcal / 515 kJ.
- Boiling barely changes the count: USDA lists boiled, drained sweet corn at 96 kcal per 100 g. Butter on the cob is where calories climb quickly.
- Canned sweetcorn, drained, is 67 kcal per 100 g but carries around 205 mg of sodium per 100 g unless you buy a no-salt-added tin.
- A cup of kernels (145 g) has about 125 kcal / 522 kJ, roughly the same as a large ear.
