Things worth knowing

• A medium baked potato (173 g) has 161 kcal / 673 kJ, while a large one (299 g) has 278 kcal / 1163 kJ, so size matters more than anything else.
• A medium potato provides about 925 mg of potassium (20% of the Daily Value) and 17 mg of vitamin C (18%).
• Much of the fibre sits in the skin: baked skin alone has 7.9 g of fibre per 100 g against 1.5 g in the flesh, while the flesh alone has the same 93 kcal per 100 g.
• A tablespoon of butter (about 102 kcal) adds well over half the energy of a medium potato. Sour cream, cheese and bacon add more, so the potato is rarely the high-calorie part of the plate.
