Raisins relieve arthritis pain and provide protection against osteoporosis. In addition, the clinical studies have found compounds in raisins that fight against tooth cavities and gum diseases.
Raisins are simply dried sweet grapes, of course. Until medieval times, raisins were the second in choice as a sweetener, honey being the top choice.
Most raisins are dried naturally by the sun right in the vineyards, although some are mechanically dehydrated. Once sun-dried, a process taking two to four weeks, they are then graded, cleaned, and packed. Some raisins are kept golden in color by the use of sulfur dioxide (sulfites).
They are produced in many regions of the world, such as the Iran, United States, Australia, Chile, Argentina, Macedonia, Mexico, Greece, Turkey, India, Pakistan, China, Afghanistan.
