On a recent trip to Melbourne to teach a nutrition workshop, Dr. Bruce Dewe also took time out to visit one of our first year classes at KC.
 
Dr. Dewe talked on the ethical dilemma facing practitioners regarding supplementation and the importance to him of using products that were human-food-chain natural, based on nature's blueprint and backed by solid science.

One example he used concerned the anti-oxidants called carotenoids. Most supplement manufacturers use as their source Dunaliella salina, an algae harvested from saltwater lakes in South Australia (Whyalla to be precise). In contrast, Dr. Dewe recommends a Carotenoid Complex made from organic fruit (apricots, peaches and strawberries) and vegetables (tomatoes, red capsicums and spinach). He is pictured (above) explaining that the algae Dunaliella salina is not eaten by fish, birds or animals and asking the students "is it then ethical to sell it to humans as a food supplement?"

As Dr. Dewe said, "We know the long-term effects of eating fruit and vegetables but we do not know the long-term effects of consuming a sea algae that other creatures avoid eating."
