High glycaemic index (GI) foods are bad for me

Really? No. Not all the food you choose needs to be low GI.

That would go against the number one healthy eating guideline: eat a wide variety of foods. So if you love watermelon (GI = 72), eat it for dessert after a low-GI main.

People with diabetes need high-GI foods if their blood glucose levels drop too low. Some jam or juice quickly restores the blood glucose level but to maintain it, they need to be followed up with a lower-GI food mixed with protein such as a peanut butter sandwich.

High-GI foods also help athletes recover from a hard training session by quickly refilling depleted carbohydrate stores. For optimum recovery, sports dietitians recommend athletes combine high-GI foods with protein.
