Strawberries - best organic and fresh

On the berry theme, back to strawberries this time. A resent study looked at organic and conventional strawberries and the effect of storage on the antioxidant levels. The conclusion was:
  • Organic strawberries had higher levels of antioxidant enzymes
  • Organic strawberries had higher levels of total antioxidant compounds (eg higher flavonoid levels than conventional systems)
  • That strawberries stored at 10 degrees C had higher levels of antioxidants than the 5 or 0 degree storage temperatures
Guess what - strawberries are stored in the fridge/cooler at approximately 5 degrees cause that makes them last longer! (about a week or so) So in conclusion, purchase fresh organic strawberries from the grower and eat them asap.
