Why do people take grapes into hostipal when they are visiting patients?

Well if you're in the hospital it USUALLY means you're ill & Grapes have important health benefits...

The skin and seeds of red and purple grapes contain a powerful antioxidant called resveratrol, a member of the flavonoid family. Flavonoids are plant pigments responsible for the vibrant red, blue and purple colours in frutta and vegetables and many times più potent than vitamin C. Resveratrol is both water and fat-soluble and therefore even più versatile than vitamins at protecting body tissues.
It improves circulation, protects the skin from wrinkles and lack of elasticity, promotes healing and may reduce inflammatory conditions such as arthritis.

because the Cibo in hospitals is crap :D

edible aramgements, man!!

Because being in a hospital means te are ill, people associate frutta as a cure for being ill.

idk. do they? lol *confused* :/ hehe
