Sweetique Eggs contain hazelnuts. Almonds and peanuts are among the other popular nuts found in chocolates and desserts made with chocolate.
From the standpoint of eating pleasure, nuts go very well with chocolate. Whether they just add complexity to the flavor, as in the Sweetique Eggs, or give crunch and interest to the texture as well, nuts are a plus.
What about from the standpoint of health? We know that chocolate itself has health benefits, but we're also often warned that additions to chocolate can limit the health value.
Fortunately, nuts are low in saturated fat, cholesterol-free, and contain antioxidants, protein, vitamins, and minerals. Studies suggest that eating nuts regularly is beneficial for health in a variety of ways.
Finally, in the context of chocolate in particular, nuts are good guys in the pantheon of chocolate fillings. Nougat, caramel, marshmallow, and similar candy bar fillings are composed entirely of sugar -- or sometimes of fat and sugar, and the fats in question are generally either tropical fats or butter, so we're talking about saturated fats. Fine chocolate with nuts is a healthier choice for those occasions when you decide to indulge in sweets.
