Dry fruits are a snack food consisting of any mixture of mechanically or manually combined nuts. Peanuts (actually a legume), almonds, walnuts, Brazil nuts, cashews, hazelnuts (filberts), and pecans are common constituents of mixed nuts. Mixed nuts may be salted, roasted, cooked, or blanched.
In addition to being eaten directly, mixed nuts can be used in cooking, such as for Tunisian farka, tarts, and toffee. Trail mix consists of nuts mixed with raisins and other dry ingredients.
A Harvard University Professor of Nutrition and Epidemiology, Dr. Frank Hu, reports that recent studies found daily nut-eaters were less likely to die of cancer, heart disease and respiratory disease.
The phrase “mixed nuts” is also used to indicate a mixture of disparate elements other than nuts, as in the film Mixed Nuts.
When a container of mixed nuts is opened after it has been shaken, the larger nuts tend to be on top. This phenomenon is known as the Brazil nut effect in the study of granular materials.
