Why Do Potatoes Raise Blood Glucose More Than Sugar?

Did you know that potatoes have a relatively high glycemic index ( GI ) score ? The GI rates how much certain foods raise your blood glucose. Each kind of potato has a different index score, but many of them fall between 80 and 90 .

Potatoes are a staple in diets throughout the world because they are an low-cost and alimentary vegetable. People who choose to limit high-glucose foods would n’t obviously avoid potatoes because we often associate high gear GI foods with those foods that contain carbohydrate .

So how is it that potatoes have a high GI score ? It ‘s all about the starch and how it converts to glucose in your body .

The Starch Effect

excessively often, glucose is associated with bouquet. regular white potatoes are not a food that is considered sweet or “ sugary. ” however, potatoes are about all starch and starch is made up of long strings of glucose .

Since the starch in potatoes is quickly digested, the glycemic index of potatoes can be about american samoa high as that of glucose entirely. The glycemic index of glucose is 100 points ; potatoes are normally listed as being in the high 80s or low 90s .

however, potatoes have a higher GI score than mesa sugar. How is that possible ? Sucrose ( mesa sugar ) has a GI of 59. It is a disaccharide ( two sugar ) molecule made up of one glucose molecule and one fructose atom. Fructose is processed differently in your body than glucose, and it does n’t affect your lineage sugar as much .

An ounce of carbohydrate from potatoes has twice a much glucose as carbohydrate. When you think of it that manner, it ‘s alone legitimate that potatoes would raise lineage glucose more significantly than postpone sugar .

however, not all potatoes are created peer, and there are ways to lower their shock on your blood glucose. You can still enjoy a few potatoes here and there ; just keep your servings in check .

The starch in potatoes is converted to sugar in your body. For that cause, potatoes can have a more meaning effect on blood glucose than table sugar.

Factors to Consider

Two chief factors that influence the glycemic index of potatoes include the diverseness and the cook method .

variety show

There are many varieties of potatoes and it would not be accurate to say that every potato has a glycemic index of 80 or 90. In fact, researchers have found that some varieties of potatoes can be a low as 53 on the glycemic index .

In one report, researchers put seven potato varieties to the test : Russet Burbank, Mayflower, Nicola, Bintje, Carisma, Desiree, and Virginia Rose. Of these, they found that the Carisma potato had a GI of 53, making it the only one of the group to be classified as low-GI.

The Nicola was the following highest at 69 GI, falling into the medium-GI class. Russet Burbank potatoes, which are identical democratic, ranked the highest at 82 GI. In general, potatoes can range in GI prize from 53 to 111, with whiten potatoes typically showing up lower on the index. Leaving the peel on adds fiber, which can reduce the potato ‘s consequence on glucose .

much, the fresh potato is rated with a GI in the mid-40s .

Cooking Method

The room you prepare your potatoes, including cooking method acting and added ingredients, can besides have an impact on the glycemic affect .

A learn published by the Journal of the American Dietetic Association examined how different cook methods affect the glucose response of potatoes. Researchers found that the room that potatoes are cook plays a big role .

Researchers advise consumers to precook potatoes and consume them cold or reheated if they want to minimize glycemic impact. Instant mashed potatoes and boiled bolshevik potatoes elicited the highest glycemic response. Roasting potatoes and bake potatoes had a slenderly lower glycemic response.

Concerns About GI

There has been refer over the accuracy and the effectiveness of using GI for managing lineage sugar. One issue is the accuracy of testing procedures. A problem arises in that the tests for the glycemic index merely show an average, while the glycemic index number itself is actually an average of those averages .

In the character of potatoes, the different studies used to compute the index have results ranging from 53 to 111. Each of those studies was run on a number of people and entirely the average was reported. so, the glycemic index count itself may not be accurate adequate to be helpful .

other researchers have reported that using the glycemic index alone may not provide significant health benefits. Some studies have shown that the exponent can be helpful in the management of diabetes, fleshiness, and cardiovascular disease risk. other studies have found the opposite.

Should You Limit Potatoes ?

There are different factors that you should consider when deciding whether or not to include potatoes in your low GI diet .

Personalized reception

different people have different glycemic responses to unlike foods. The most significant factor is how your own body reacts to a potato. You can get this data with a rake glucose meter .

This information is specially authoritative if your body is on the diabetes spectrum and does n’t process sugars well. High blood sugars take a bell on your body, making wrong to your pancreas and other complications from diabetes more likely .

part size

Potatoes have many nutritional benefits. A single service of potatoes is considered to be 150 grams. The glycemic load ( and glycemic reply ) will depend on how much you eat at one clock and what other foods you have with the potatoes .

Most of the meter, potatoes are eaten as part of a meal quite than by themselves and that will modify how they affect your rake glucose. For example, if you eat low-carb kernel with a small potato english and a salad, the meal is balanced. The other foods can actually reduce the effect the potatoes have on your glucose .

The same can be said for low glycemic foods like beans and many vegetables. If you cook potatoes in a dish that has enough of healthy adipose tissue, protein, or fiber, the glucose effects are besides diminished .

A Word From Verywell

While potatoes can be quite high in glucose, keep in heed the things you can do to reduce it. If you want to eat potatoes, select a lower GI potato variety, enjoy smaller servings, and pair them with foods that counteract the glucose. Most importantly, monitor your blood glucose and see how these changes affect you personally .
