Some have the kind of texture that mashes well while others are too waxy to mash but make great potato salad, staying firm and full of flavour with just the right amount of dressing sticking to their ribs. Other potatoes are superb for baking, steaming or microwaving and some make great chips. However, there are some features that are common to all potatoes. All potatoes are a good source of complex carbohydrate. Potatoes are one of the most filling foods.
All potatoes contribute dietary fibre.
No potato contains fat. Many people used to think that potatoes were fattening. We now know that carbo- hydrates of the type found in potatoes are not converted to fat unless you consume an enormous quantity. This carbohydrate is not stored in the body, so eating your 4kg over a week or two would not lead to extra fat stores. However, the butter, margarine, oil, sour cream or any other type of fat used when preparing or serving potatoes, can be fattening.
