Can you tell which food is higher on the glycemic index?

White rice has a high glycemic index, around 72. Barley and quinoa are typically low glycemic foods.

Sweet potatoes are a bit sweeter than the other veggies on this list, and their GI of about 70 reflects that. Interestingly, yams are considered marginally low glycemic, with an average value of 54.

Mahatma basmati rice has a GI of 58, and the grain as a whole runs in the high 50s and lower 60s for GI values.

Grapes are marginally high glycemic, with a value of 59. Broccoli and tilapia are all great choices for a low glycemic meal.

Shortbread is the highest GI item listed here, with an average glycemic index of 64. Corn on the cob and steak are low glycemic foods.

Salmon, brisket, and avocados are so low on the glycemic index that they don't have a value (or if they did, it would effectively be zero). That's because their sugar and starch content is nonexistent!

Fruit Roll-Ups are essentially just sugar, and they have a whopping glycemic index of 99. Since pure sugar has a GI of 100, it's hard to come up with a snack that has a higher GI than that!

Glycemic index data for nuts is scarce because they are so low on the index, but it appears that cashews are the highest with an average GI of 22, considerably higher than even peanuts, which come in at 13.

In most cases, ice cream still has a higher GI than pears. As it turns out, though, some brands of ice cream, often premium, can have a lower GI than many fruits.

Baked potatoes may be a food to avoid when you're on a low glycemic diet. Baked russets actually have a glycemic index of 111!

This traditional addition to Southern meals is actually one of the higher GI foods among the legume family, at 50 GI. Nonetheless, all legumes are considered low GI.

While all of these fruits are low glycemic index foods, a banana has the highest GI value, at 48. When it comes to their full effects, however, dates carry a higher glycemic load of 18, versus bananas' GL of 11.

Pretzels often land in the upper 80s, making them a bad food to choose on a low glycemic diet. French fries are usually high glycemic, but trend in the 50s and 60s.

Grape-nuts are touted as a healthy breakfast, but anyone watching blood sugar should beware: they have a glycemic index of 75 and a glycemic load of 16.

Puffed wheat cereals have a surprisingly high GI of 80. Bacon, grapefruit and apple juice all have significantly lower GI values than puffed wheat.

Honey has an average GI value of 61, making it on the low end of high glycemic sweeteners. Compared to glucose, at 100, that's pretty good!

Peanut M&Ms are actually low glycemic, but Skittles and Live Savers are definitely high glycemic. Whether a candy is high or low GI depends greatly on the primary ingredients and the amount of sugar added.

Surprisingly, green peas have a slightly higher average GI than a supreme pizza! That's not the final word on the matter, though: overall, the peas have a lower glycemic load, at 4, compared to 9 for the pizza, meaning the peas' overall effect on the body's glucose levels is less of a problem.

Not surprisingly, the sugary, chocolate-flavored cereal is higher on the glycemic index than the other cereals, which make at least some attempt at being healthy.

Chickpeas are very low on the glycemic index with a value of 10, reduced-fat yogurt with fruit averages around 33, and plain orange slices come in at 45 on average. Since they're all below 55, they're considered low glycemic.

On average, corn flakes have a higher GI, at 81, than store-bought waffles, but all of these foods are high on the glycemic index. Which brand you buy can make a big difference, though - if your corn flakes are coated in a layer of sugar, they'll have a much higher GI than plain corn flakes.

Most products made directly with milk are low GI foods, and yogurt (even with fruit added) is no exception. But, fruity yogurt cups still have a higher GI than plain milk and cheese.

The French baguette is our culprit here, with an average GI of 95. It's almost as bad as eating pure sugar - at least as far as your insulin level is concerned.

Despite the toffee flavoring, Bulla ice cream has a GI of about 27, while honey sits at 61. Ice cream GI varies by brand, but often comes in as low glycemic overall.

Honey has a GI value of 61, whereas most agave nectar has a GI around 30, depending on brand. There's some controversy regarding the overall effect of agave in individuals with diabetes, but there's no debating the low GI of agave nectar.

It's tempting to think strawberry jam would be the worst offender since its main ingredients are berries and sugar, but it turns out that strawberry fruit bars have average GI values in the low 90s, much higher than jam's average of 51.

Unless you're adding spoonfuls of sugar to your salsa, or your bean dips for that matter, none of these foods should be high glycemic. Legumes like chickpeas and black beans are low glycemic, as are the fresh veggies and fruits used for salsa.

As it turns out, Gatorade has a pretty high glycemic index, around 89. Nevertheless, its glycemic load is still less than that of Coca-Cola.

Instant oatmeal has a GI of 79, watermelon has a GI of 72, and vanilla cake from a mix with frosting only has a GI of 42. But don't let the GI fool you: vanilla cake's glycemic load averages around 24 (fairly high) while watermelon's is only about 4 (really low).

Vanilla wafers, on average, have a slightly higher GI than packaged waffles.

Oven baked pretzels typically have a GI around 80, making them the highest GI item on this list. Regardless, all these snack foods are considered high GI foods.

Steamed brown rice only has a glycemic index of 50, and corn chips follow closely at 42. That means both are considered low glycemic index foods.

There are many differences which make it impossible to categorize one as higher GI than the other. Is the burger with or without a bun? What flour was used for the pizza crust, and what were the toppings? How much is a serving?Pizza alone can range from mid-30s to low 80s, depending on the circumstances.
