Energy
Carbohydrates supply half your daily needs.
Starchy foods like potatoes are a good source of energy. For a balanced diet, carbohydrates should supply just over half your daily calories or energy needs. Most of your carbohydrates should come from complex carbohydrates. The big advantage of getting your carbohydrates from potatoes, rather than pasta or rice, is that you also get an abundance of other vital nutrients. Potatoes contain more fibre, potassium, iron and folate than rice or pasta. And they are packed with Vitamin C - which neither rice nor pasta contain.
This works out that your main meal of the day should look a bit like this (ideally you will get the other quarter of your complex carbohydrates from breads and cereals at breakfast or lunch.)
Potatoes are better than rice and pasta because they suppy a wealth of other vital nutrients.
