This is why the GI of some foods can be surprising. For example, ice cream has a relatively low GI, because of the fat content. This means that should you get low- or non-fat ice cream, it may have a higher GI [because of the sugar added to hide the lack of flavor lost when the fat was removed, which may also supply more calories than you want] and is probably a poorer choice than the higher fat version for weight-loss purposes (although, total calorie content must also be considered.)”5
Carbohydrates are rarely eaten alone; most often, you eat them in combination with other nutrients, which is good. When fat, protein and fiber are eaten with carbs, the carb’s GI rating drops, so that you benefit from a slower release of energy. A carb food with a moderately high GI rating, such as white spaghetti, gets a lower score when eaten with a sauce containing some fat and protein.
Note: A food’s GI rating is just an analytical tool to help you choose quality foods that provide energy that lasts throughout your school or workday and into the evening for your martial arts class. Think of the GI as a pretty darn good rule of thumb rather than as a strict guideline.
