While 10% of your diet should be of starchy carbohydrates, it should be noted that if most of this is of naturally grown foods such as yams, potatoes, green bananas etc., it would be more beneficial. While there are those discouraging from the use of salt (sodium chloride) it should be noted that 1). It is impossible to avoid sodium and 2).
