Glycemic Index - a clue to healthier eating

As always, I get stuck at home due to the bad weather outside, and because there ain't anywhere worthwhile to go without spending big money, I'm bored stiff, apart from whatever Playstation 2 and computer games are available to me while I'm still killing time during this long waiting period after the O Level major examinations.

So, I just did a little Net-surfing and found this familiar topic that appeared in the Biology textbook - the glycemic index. Basically, glycemic index isn't some complicated topic after all.

Simply put, glycemic index is a measure of how fast the carbohydrates in food are released into the bloodstream. The higher the index of a particular food, the faster the glucose derived from the digested food gets absorbed into the bloodstream. So, to quote a few examples,

Foods with high glycemic index(GI): potatoes, bread, corn flakes, sweets, cereal, etc.
Foods with low GI: foods like nuts, milk, fruit and veg., chicken and fish.

So, to ensure your blood glucose stays steady I'd suggest you eat more fruit and veg, and nuts are a good thing to snack on if you're gonna burn midnight oil. For a quick fix just grab the nearest chocolate bar. However, that doesn't mean eating nuts despite food allergies, so don't use this information provided against me when stuff like that happens, okay?

Still trying to kill time after sharing this to Netizens reading this entry.
