Many of the foods we think of casually as fruits, such as rhubarb (of which we eat the leaf stalks), are not fruits at all, and many of our favorite “vegetables” actually fit the definition of fruit, such as the tomato.
As a subcategory of fruits, berries are yet another story. A berry is a a fruit that does not split apart at maturity which is derived from a single ovary and having the whole wall fleshy. Berries are not all tiny, and they’re not all sweet. Surprisingly, eggplants, tomatoes, bananas and avocados are botanically classified as berries! And the popular strawberry is not a berry at all.
Botanists call the strawberry a “false fruit,” a pseudocarp. A strawberry is actually a multiple fruit which consists of many tiny individual fruits embedded in a fleshy receptacle. The brownish or whitish specks, which are commonly considered seeds, are the true fruits, called achenes, and each of them surrounds a tiny seed.
These achenes also make strawberries relatively high in fiber. According to the Wellness Encyclopedia of Food and Nutrition, one-half cup of strawberries supplies more fiber than a slice of whole wheat bread, and more than 70 percent of the recommended daily allowance of vitamin C.
