To add to that, raisins contain a high amount of the trace element boron. Boron works with vitamin D and calcium to keep your bones and joints healthy. It also plays a role in treating osteoporosis.

Raisins are an exceptional source of naturally occurring chemicals called phytonutrients, such as phenols and polyphenols. These types of nutrients are considered antioxidants.

Antioxidants help remove free radicals from your blood and may prevent damage to your cells and DNA.
