Potato

If You Read Nothing Else

A medium potato with the skin on gives about 2 g of fibre and more potassium than a banana.

How you cook it matters more than the potato itself: boiled and fried are nutritionally different foods.

Cooked and then cooled, potato forms resistant starch, which behaves more like fibre.

Green or sprouted potatoes contain solanine. Throw them out rather than cutting the green off.
