Pineapple

"Luscious, tart-sweet pineapple is full of nutrients as well as
flavor. In addition to supplying vitamin C, a cup contains your daily
quota of manganese, a trace mineral that promotes bone health. Though
available all year round, this tropical fruit is at its peak from March
through June. Go ahead and cut it into chunks and store in the fridge
or buy it precut for convenience-the fruit retains its nutritional punch
for up to a week."
