With their relatively high in complex carbohydrates (starch) potatoes can help to rebalance the diet (today, often high in fat and deficient in complex carbohydrates). This, of course, provided to choose the methods of preparation preferably less fat (these are also the most digestible!). See below the energy intake of each type of preparation of potatoes. In exchange, the appetite will be perfectly happy without entailing excessive caloric adds.

Their vitamin C is even more interesting that the potatoes can be consumed regularly and in significant quantity (a small portion is about 200g). Thus, given the losses in cooking, a dish of potato provides about 18 mg of vitamin C per person (over 20% of daily needs). And if they are new potatoes, this contribution may exceed 35 mg (almost half the daily requirement).

Potatoes also contribute effectively to the supply of magnesium, often deficient in the diet: one serving of 200 g of potatoes provides 50 mg (which is substantial, given the daily needs of about 350 mg) . To best protect the magnesium content of potato, prefer steaming, or baking (rather than cooking in water). They also allow a further significant amount of iron.
