Can Guinea Pigs Eat Potatoes?

Let’s jump into the question right away

What is the Nutritional Value of Potatoes?

Potatoes with intact skins aren’t really different from the ones without skins. But, the skins do contribute to the fiber percentage of potatoes because more than 50% of it is present there.

Why Are Potatoes Lethal to Guinea Pigs?

Potatoes are best kept away from guinea pigs. They contain two different classes of alkaloids, glycoalkaloids, and the calystegines, both of which are known to be toxic to guinea pigs.

In fact, some studies mention that glycoalkaloids in potatoes can be toxic to humans as well. But that’s a discussion for another day.

The precise reason why potatoes are lethal to guinea pigs is because of the presence of solanine. It’s a steroidal alkaloid saponin that can harm your pet guinea pigs severely. You should keep potatoes away from their diet.

Weight gain from potatoes for GPs

Guinea pigs can definitely get fat by eating potatoes. That’s because potatoes contain high amounts of carbohydrates. But weight gain shouldn’t be the primary worry when your guinea pig eats potatoes.

There are other negative impacts, besides weight gain, that can harm your guinea pigs. Potatoes contain solanine which is a toxic alkaloid that can harm your pet when consumed regularly.

Guinea pigs have sensitive stomachs, and regular potato consumption can even result in the death of your guinea pig. So it’s best that you don’t incorporate potatoes into the regular diet menu of your pet guinea pigs.

There are lots of other options that are safe for them. Try and explore those and keep potatoes at bay.

Complex Sugars In Potatoes Good For Guinea Pigs?

This simple answer is a no. Guinea pigs don’t have a robust digestive system that can handle complex sugars present in potatoes.

Even if we overlook the negative impacts of solanine, complex sugars themselves can cause damage to guinea pigs and make them diabetic.

It’s best that you feed them the routine hay combined with several other permissible vegetables that are healthy for the guinea pigs.

So now, whenever the question ‘can guinea pigs eat potatoes?’ arise in your mind, know that the answer is a firm no because of toxic alkaloids and complex sugars. Let’s look at the question in a little more detail below:

–          Resistant starch in potatoes

Potatoes are starchy foods. But they have starch that’s indigestible by the guinea pig system. That’s why the starch remains undigested in their bodies and causes problems.

–          Alkaloids – Glycoalkaloids are present in potatoes

The presence of glycoalkaloids in potatoes is an issue because they are toxic alkaloids that can damage the bodily systems of a guinea pig.

–          Calcium

Calcium is a necessity for guinea pigs, especially when they are in their growing stages. But sourcing calcium from potatoes isn’t the ideal thing because with it come the negative components of potatoes as well.

The best practice is to give safer foods with calcium to your guinea pigs.

–          Surplus Fructose

Fructose is a form of complex sugar. It’s harmful to the guinea pigs, and their system can collapse upon excessive potato consumption.

How Much Potatoes Can a Guinea Pig Eat?

The quantity that harms the animal differs from one cavy to another, but daily consumption will be harmful to all.

Can Guinea Pigs Eat Sweet Potatoes Leaves?

No. Even the potato leaves contain solanine which is a toxic alkaloid that’s harmful to guinea pigs.
