Raisins pack more nutrition than their small size might indicate. When grapes are dehydrated to produce raisins, the nutrients become more concentrated, making a handful of raisins a snack rich in B vitamins, iron and potassium. Besides nutrients, raisins are also a good source of carbohydrates for energy.

eating Raisins Every Day

One of the biggest benefits of eating raisins is that they’re a quick, easy and tasty way to get some of your daily recommended fruit servings. Women should eat at least 1.5 cups of fruit daily and men should have 2 cups, according to ChooseMyPlate.gov. One small box of raisins, which is 1.5 ounces and holds about 90 raisins, fills one-half cup of your daily fruit requirement, plus it only has 129 calories and no fat.
Carbohydrates for Energy

The 34 grams of carbohydrates in one small box of raisins include 26 grams of sugar for rapid energy. If you use sports chews or other sports products to add carbohydrates and improve performance while you exercise or participate in endurance sports, you can get the same benefit from eating raisins, according to a review in the Journal of Food Science in 2013.
Iron

Eating raisins every day helps you meet your daily requirement for iron. Even though most of the iron in the body carries oxygen in red blood cells, it’s also present in every cell in your body because it has so many other jobs. It supports your immune system, helps make amino acids and it’s essential for metabolism.
Potassium

Potassium is able to carry electrical charges that cause muscle contraction and stimulate nerve impulses. It’s especially vital for your heart because potassium regulates the heart beat and also helps lower blood pressure by limiting the effect of sodium. Special structures in your body work constantly to maintain a strict concentration of potassium in the cells.
