History of the strawberry
• The history of this fruit goes back as far as the Romans and perhaps even the Greeks,
• The reference of strawberry appears in the thirteenth century in the writings of a Greek doctor, Nicholas Myrepsus,
• The literature of botany was often the literature of medicine, where plants were described for their use in treating ailments,
• By the 1300's, the strawberry was in cultivation in Europe,
• At first the plant was considered more ornamental for its flowers than useful for it fruit,
• Strawberries were served at medieval state events, they symbolized prosperity, peace, and perfection,
• Nowadays strawberries and cream is a popular dessert, famously consumed at Wimbledon.

Health Benefits
• The berries are non-fat and low in calories,
• They are rich in: – potassium,
– folic acid,
– fiber,
– and vitamin B6.
• Over history the strawberries have been used in medicines for sunburn, discolored teeth, digestion, and gout.
• Strawberries contain fisetin, an antioxidant that has been studied in relation to Alzheimer's disease and to kidney failure resulting from diabetes.

Allergy
• Some people experience an anaphylactoid reaction to the
consumption of strawberries.
• The most common form of this reaction is oral allergy
syndrome, but symptoms may also mimic hay fever or include
dermatitis or hives.
• May cause breathing problems.
• Some research suggests that the allergen may be tied to a
protein involved in the ripening of fruits, which was named Fra
a1 (Fragaria allergen1).
• White-fruited strawberry cultivars, lacking Fra a1, may be an
option for strawberry allergy sufferers. Since they lack a
protein necessary for normal ripening, they do not produce the
flavonoids that turn the mature berries of other cultivars red.
