I got this recipe from 'The top 100 juices' by Sarah Owen, published by Lifetime Distributors, Castle Hill, Australia.
Sarah Owen says "All three fruits in this juice provide a massive infection-fighting boost of vitamin C and can help to shorten the duration of a cold. The kiwi fruit a also contain lutein, a phytonutrient known to reduce the risk of cancer, heart disease and eye disease. Both strawberries and grapes are high in ellagic acid, which neutralizes carcinogens. The tannins, flavones and active compounds in the grapes combine to make them energizing and strengthen the cell walls of blood vessels"
You could make more than one serving, and serve with lemonade and ice in a punch bowl for a party if desired.
I haven't made this yet, as I don't have a juicer, but if I ever get one, this will be the first juice that I make.
