Sweetness can come from many places.
A relaxed walk after a satisfying meal can offer the body a “sweet” treat that aids digestion and boosts the mind. A conversation filled with smiles and kind words can satisfy the desire for security, even more than chocolate can. An after-dinner enjoyment of a favorite pastime or hobby can assuage the appetite for sugar. A meal that gives entertainment to the senses through appetizing aromas and flavors needs no aftertaste of dessert.
Dessert that is nutritionally sound provides sweetness within context of a nutritionally sound meal. Dessert that is nutritionally bereft tantalizes the eyes and pleases the mouth, but upsets the digestive system and causes myriad negative irritations in the body.
When the urge for sweetness overcomes sensible treatment of the body, remember that there are dessert substitutes that satisfy the calls for momentary gratification, escape from unhappiness, or sweet addiction.
