It doesn't. A raisin has as much sugar as a grape, assuming the producer didn't add corn syrup or sugar to the raisins. Because, however, raisins have had most of the water removed, the amount of sugar per ounce is going to be much more for raisins than fresh fruit. An ounce of raisins might contain several dozen raisins (which have the sugar of several dozen grapes) versus an ounce of grapes, which contains, perhaps, 8 grapes (the sugar content of 8 raisins). Removing water from the fruit is going to make it appear more concentrated, even though you'll be consuming the same amount of sugar per fruit. Again, this assumes the dried fruit hasn't had extra sugar added.
Pecans are native to the central and eastern parts of the United States and parts of Mexico. Its earliest history can be traced to the 16th century. Back then, the nuts were named pecan -- a Native American term that described, "nuts that need a stone to crack it." I cannot find the term, "shay" associated with pecans. There is a shea tree that is native to Africa. The shea fruit contains an oily seed which is used to make shea butter. Shea butter is used in creams, lotions, and cosmetics.
