Whole food

If someone has a genetic predisposition to diabetes, it means that simple carbohydrates such as potatoes, white rice or pasta may trigger the disease. This sort of person needs to switch to whole-grain products. For others, it is less important. People who are susceptible to obesity, on the other hand, should cut down on fiber-rich products because – for example – a slice of pumpernickel has the same energy density as eight slices of toast and yet they are tempted to consume the same volume as before.
