Are Bananas Good for Guinea Pigs? | Health Benefits

Are Bananas Good for Guinea Pigs Health Benefits

Bananas Are Good for Young Guinea Pigs

Bananas are very healthy for humans and are especially consumed by sports players due to the high amount of potassium. The same is applied to the guinea pigs but not for the adult ones, in this case, potassium is most beneficial for the baby guinea pigs. Combined with a high protein diet, potassium improves growth in young guinea pigs.

Lowers the Chance of Getting Kidney Stones

Guinea pigs are prone to kidney stones. Bananas with a high amount of potassium are a great way to prevent this. In order for guinea pigs to have healthy kidneys, they need a regular intake of potassium.

Scurvy Prevention

Bananas contain vitamin C which is also extremely important to guinea pigs. Just like us, they can’t produce vitamin C within their bodies and they need an external source. Lack of vitamin C can cause a disease called scurvy. This is where bananas can help because they contain vitamin C but are only helpful if consumed moderately.

Bananas are low in fats and cholesterol but at the same time, are high in sugar and this is why you have to be careful when giving them to guinea pigs.

This is the nutritional chart for 100 g of bananas (around 3.5 oz of bananas):

  • Energy – 89 kcal

Risks to Consider When Guinea Pigs Eat Bananas

As much as bananas are good for growth and for the health of the kidneys, they also contain certain risks. Now let’s explore these risks.

Problems With Kidneys

Even though we said that bananas can help with preventing kidney stones, if the guinea pig’s kidneys are not functioning well, the bananas and the potassium that they contain can result in the guinea pig’s death. When kidneys are not working properly, they are not able to remove the excess potassium from the body. If that happens, the guinea pig can die.

This is why it is very important not to feed them bananas if they have any form of kidney disease. Only feed them bananas to maintain the health of the kidneys and if kidneys are healthy.

Guinea Pigs Can’t Consume Sugars

Also, bananas contain lots of sugar that can cause problems and constipation for guinea pigs. Bananas are fibrous food and lots of fiber can also cause problems. These problems can manifest in the form of stomach bloat, gases, and cramps. All of this can cause the guinea pig extreme pain. So, avoid giving them too much of anything and this includes bananas as well.
