• Do potatoes spike insulin?

So let us get started already!

Are Potatoes Safe in Diabetes?

Why are potatoes considered a threat to diabetic health?

Diabetes is an unhealthy condition that takes place in the body due to insufficient amounts of insulin production. Insulin is a hormone that regulated the body’s metabolic functions.

It is useful in promoting the breakdown of food and nutrients for easy usage in the body. It helps in the metabolism of carbohydrates into simpler sugars that are easier for the body to gain energy.

Due to insufficient production and functioning of insulin in the body, the blood sugar levels are affected. The sugar, when it is unable to be broken down, stays in the bloodstream.

This leads to the accumulation of sugar in the blood instead of being used in the body to produce energy. This gives rise to higher blood sugar levels in the body, which is the main concern for diabetics.

Potatoes are vegetables known for their richness in starch. Starch is a carbohydrate, and therefore, the intake of potatoes is said to be bad for the diabetic body.

There are various types of potatoes found with different nutritional profiles. There are also plenty of ways to cook them. These are all factors that affect the influence of potatoes on the body’s blood sugar levels.

For now, let us move on to our next essential question.

Can diabetics eat Potatoes?

As we already mentioned, potatoes are harmful to diabetic patients due to their carbohydrate content. But it is not very risky to diabetic health when taken in moderate and safe amounts.

Thus, there are some rules and regulations to keep in mind before deciding to include or exclude the potato in your everyday diet.

The potato is not the best for diabetics, but that does not mean you can eliminate it from your diet. You can keep it in your meal plans as long as you apply your acquired information about its safe usage.

We are here, ready to help you do it better.

Potato is a vegetable that is a stem of the plant. Similar to taro, yam, sweet potato, etc., this is also full of starch.

First of all, potatoes are found in different varieties. Some have higher starch content, and some with a lower amount of starch.

It is also important to understand that the starch found in potatoes is complex carbohydrates. These complex carbohydrates take much longer time to digest and help keep the blood sugar levels low and under control.

Unlike simple carbs and sugar, complex carbs are harder to digest and breakdown. As they take more time, it results in a slow absorption and release of sugars in the bloodstream. This, in turn, assists in keeping the body’s blood sugar levels under normal margins.

Nevertheless, an unwatched intake and higher than the recommended quantity of potatoes can heighten the body’s blood sugar levels. It can also increase the vulnerability of acquiring Type 2 Diabetes.

Therefore, a healthy and safe daily limit is very necessary for the body. Wondering what this daily limit is? We will tell you in the later sections. But first, let us answer another question –

Do Potatoes spike insulin?

Well, potatoes can lead to spikes in insulin and blood sugars. But as we suggested earlier, fewer amounts of it can be safe.

These things also highly affect the Glycemic Index of this starchy vegetable. Let us discuss the glycemic index of potatoes to better look at its effects on diabetic health.

There are ways to prepare your potatoes to reduce their overall glycemic index as well as glycemic load.

There are plenty of ways to make potatoes. Some of the most common ones are – mashed, boiled, fried, and roasted potatoes. You can derive that fried potatoes use up oil and, hence, rise on the glycemic scale due to fats’ addition.
