Eureka! A spud with a GI of 58 plus new values for parsnip, pumpkin, nectarines and hummus
Fiona at SUGiRS has been working overtime this month and has sent us the GI values for several popular staple foods. First of all she discovered a lower GI potato thanks to chef and potato expert Graham Liney, owner of restaurant/guest house Willow Vale Mill, near Goulburn. Less than a year ago, Fiona, Jennie and Philippa sat down with Graham and asked him what sort of potato he thought might have a lower GI. He suggested we check out a general purpose, waxy variety called Nicola, which is what’s known in the trade as a ‘hard cooking’ potato (doesn’t go mushy) that’s suitable for potato salads as well as steaming, boiling or baking. He was spot on. Nicola potatoes have a GI of 58. They are available in major supermarkets and produce markets as well as farmers’ markets and from organic growers around the world. Remember, however, to keep those portions moderate. For more information about Nicola potatoes contact: Graham Liney, Willow Vale Mill, Laggan, Ph: 612 4837 3319 Fax: 612 4837 3343
Graham's tips for baking potatoes
- Scrub potatoes clean then boil them for about 16–17 minutes in a pot with the skin on. They needed to be what he called ‘cooked to crunch’.
- Drain and pat dry with a clean cloth or kitchen paper.
- Place in a baking dish, spray or brush with a little olive oil and bake in a preheated oven (200ºC/400ºF) until golden and crisp on the outside.
Nectarines (fresh): GI 43
Butternut pumpkin/winter squash (boiled): GI 51
Parsnips (boiled): GI 52
As for our favourite low GI spread: hummus. We have just tested Chris brand Traditional Hummus – GI 22. But look at the GL on this one: with a 20 g serve size (about a tablespoon), you get 3.6 g carbohydrate and a GL of 1 (actually 0.8).
