Blueberries are flowering plants of the genus Vaccinium with dark blue, purple or black berries. Species in the section Cyanococcus are the most common fruits sold as "blueberries" and are mainly native to North America. They are usually erect but sometimes prostrate shrubs varying in sise from 10cm tall to 4m tall. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish. In commercial blueberry production, smaller species are known as "lowbush blueberries" (synonymous with "wild"), and the larger species as "highbush blueberries". The leaves can be either deciduous or evergreen, ovate-lanceolate, and from 1 to 8cm long and 0.5 to 3.5cm broad. The fruit is a false berry 5 to 16mm diameter with a flared crown at the end; they are pale greenish at first, then reddish-purple, and finally blue on ripening. They have a sweet taste when mature, with variable acidity. Blueberry bushes typically bear fruit from May to June though fruiting times are affected by local conditions such as altitude and latitude.

The word cherry refers to a fleshy fruit (drupe) that contains a single stony seed. The cherry belongs to the family Rosaceae, genus Prunus, along with almonds, peaches, plums, apricots and bird cherries. The subgenus, Cerasus, is distinguished by having the flowers in small corymbs of several together (not singly, nor in racemes), and by having a smooth fruit with only a weak groove or none along one side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in America, three in Europe, and the remainder in Asia.

Cranberries are a group of evergreen dwarf shrubs or trailing vines in the genus Vaccinium subgenus Oxycoccos, or in some treatments, in the distinct genus Oxycoccos. They are found in acidic bogs throughout the cooler parts of the Northern Hemisphere. Cranberries are low, creeping shrubs or vines up to 2m long and 5-20cm in height; they have slender, wiry stems that are not thickly woody and have small evergreen leaves. The flowers are dark pink, with very distinct reflexed petals, leaving the style and stamens fully exposed and pointing forward. They are pollinated by domestic honey bees. The fruit is an epigynous berry that is larger than the leaves of the plant; it is initially white, but turns a deep red when fully ripe. It is edible, with an acidic taste that can overwhelm its sweetness. The active ingredients in cranberry include chemical compounds called proanthocyanidins. Proanthocyanidins are potent antioxidants that appear to be able to decrease bacterial adherence to the bladder epithelium cells. The main benefit of this action is that bacteria have less likelihood of grouping together to cause bladder infection, urinary track infections and other related conditions. Like Chamomile, ther is some evidence that cranberries not be combined with warfarin or other medications or supplements that have the same effect or be used by people with bleeding disorders.

The word currant came into English from the Anglo-French phrase "raisin de Corauntz", that referred to small seedless raisins imported from Corinthia in southern Greece. This phrase was first attested in 1334 as "raysyn of Curans" (raisins of Corinth). The word was transferred to the unrelated northern European berries from the genus Ribes when they were introduced to England in 1578.

Phoenix dactylifera, commonly known as the Date Palm, is a palm in the genus Phoenix, extensively cultivated for its edible sweet fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15 to 25 m tall, often clumped with several trunks from a single root system, but often growing singly as well. The leaves are pinnate, 3 to 5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30cm long and 2cm broad. The full span of the crown ranges from 6 to 10 meters. Dates are a great source of dietary fibre, and according to researchers at the University of Scranton in Pennsylvania, they have the highest concentration of polyphenols among dried fruits. The findings of this research suggest that dried fruits should be a greater part of the diet because they are dense in phenol antioxidants, nutrients, and fibre.
