Kiwifruit which are grown in the Southern Hemisphere, particularly in New Zealand, are exposed to higher levels of UV light and plant’s respond to this by producing more secondary metabolites compared to plant’s grown in other countries.
Secondary metabolites are the chemicals in the plants which we now know have health benefits. They are things like polyphenols, carotenoids and anthocyanins. All of these are actually produced by the plant as a stress response to the harsh UV rays, however, research shows that they are beneficial to your health.
