Since learning about the advantages of kiwifruit in suppressing the common cold, the longest I have had a cold for in the last 8 years is for a duration of 4 days. I only develop a cold, if around virus ridden areas and a Kiwifruit is not handy. One Kiwifruit per day [150% Vitamin C requirement]everyday was My aim; however the local New World supermarket is a money whore, and still selling them at $6.95 kg (off season Italian import pricing). A supermarket 23 kms away is selling them at $0.99 kg.
