Low GI foods
Most fruits and non-starchy vegetables plus carrots, sweet potato and yams have a GI of 55 or less, as do beans and lentils. Oatmeal, oat bran, barley and bulgur wheat are examples of low GI grains. Breads with a low GI include pumpernickel and multigrain/granary bread.
Medium GI foods
Brown, wild and basmati rice are medium GI. Some breads are too, including whole wheat, rye and pita. And while regular oatmeal and oat bran have a low GI, quick-cook oats are medium GI.
High GI foods
Foods that include highly refined carbs such as white bread, rolls, bagels, pretzels, wheat crackers, white rice and rice cakes have a high GI. Potatoes have a high GI too. Some breakfast cereals such as corn flakes, puffed rice and instant oats are high GI, while fruits that are ranked high on the GI scale include melons and pineapple.
Top tips to mange GI foods:
- Try to include one low GI food with each meal.
- Choose low GI cereals – if you like porridge, make it from regular oats or oat bran, rather than quick or instant oats.
- Swap white or brown bread and rolls for bread made with grains and seeds.
- Pick sweet potato and yams instead of white potatoes (or if you’re having white potatoes, makes sure they still have their skins on).
- Try having quinoa or bulgur wheat instead of white rice, and cook your pasta until it’s al dente instead of soft (al dente pasta has a lower GI than pasta that’s been cooked for longer).
- If you don’t do so already, make beans and lentils part of your diet on a regular basis.
