Dry Fruits Offer Convenient Nutrition but Differ from Fresh in Water and Calories
Dr. Maya Rozman explains the nutritional differences between dried and fresh fruits, addressing common misconceptions. While dried fruits are often seen as "candies in disguise," this label is somewhat unfair. Fresh fruits contain high water content, which adds volume and satiety with fewer calories, making them generally more filling than dried fruits. For example, one fresh apricot occupies much more volume than one dried apricot, and it is easy to consume many dried fruits quickly without realizing the larger quantity eaten.
Rozman clarifies that comparing 100 grams of fresh fruit to 100 grams of dried fruit is misleading because drying removes water, concentrating calories, sugars, fibers, and minerals in a smaller volume. Essentially, one dried fruit piece corresponds roughly to one fresh fruit piece before drying, assuming no added sugars or ingredients. This principle applies to raisins and grapes as well. The main issue is portion size, as people tend to eat more dried fruit in one sitting.
Dried fruits retain fibers and minerals in concentrated amounts, but antioxidant levels, especially polyphenols and anthocyanins in colorful fruits like berries and cherries, may decrease due to heat and drying duration. Some dried fruits, such as cranberries, often contain added sugars to offset natural tartness, while others like raisins, dates, prunes, and apricots can be sold without added sugar. Sulfites are commonly used preservatives to maintain color and prevent browning, especially in apricots, and must be listed on labels. Sensitive individuals, particularly some asthma patients, should check for sulfite content.
A typical serving size is about 25-30 grams of dried fruit, but this varies by fruit type and size. When possible, fresh fruit is preferable due to higher water content, better satiety, and preservation of sensitive vitamins. Nonetheless, natural dried fruits remain a convenient, nutritious option for travel, hiking, flights, or when fresh fruit is unavailable, and can be added to cereals or yogurt.
