View Full Version : Glycemic Index and it's limitations

According to this link


Oatmeal is a 70 whereas there are many items which are equal or lower such as

sponge cake 66
banana cake with sugar 67
white spaghetti 59
instant noodles 67
jams and marmalades 70
mars bar 63

Aside from the fact that most of these have no nutritional value, are they REALLY equally good or better sources of carbs in terms of preventing fat storage?

Glycemic Index is a measure of the amount of Insulin 1 hour after ingestion.

Perhaps it is possible that some of these foods have resulted in an insulin peak that has come and subsided in less than an hour?

That's weird cause on the same site, i use this link (http://www.mendosa.com/dws-gi_list.htm)

BTW the glycemic index is a measure of a rise in blood glucose levels after ingesting carbohydrates, not insulin. That insulin score measures that.

use the GI as a guideline and not a be-all end-all. Too many factors can influence the GI of a food.

gi is useless for foods with simple sugars
It is useful for comparing complex carbs though

anything under 70 for complex carbs good to eat when leaning?

its unlike the level of glucose will peak before 1 hour as it will take a while to digest. it may peak under a hour if a small portion of food is consumed. but then thats more to do as, the body can deal with it quickly.

Foods may take longer to peak if you are dehydrated and eat a big meal as it will take longer for the glucose to reach your blood. so the peak may be flatter, but it will take longer to get their.
