On the wrappers of most Swiss chocolates nutritive and energy values 
	are stated. A detailed analysis of chocolate reveals notable amounts of 
	the most important nutritional components: rarely are so many natural 
	constituents and so much energy concentrated in such a small space. An 
	average bar (100 g) of good quality chocolate contains the following 
	components:

	These values can of course be changed by the presence of additives e.g. 
	wal-nuts, hazel-nuts, almonds, raisins and other dried or candied fruit. 
	Further the dried milk content of a 4 oz. bar of milk chocolate is roughly 
	the equivalent of a large glass of fresh milk. Chocolate in fact is both a 
	high-grade, natural food and an exquisite luxury!
