Can Guinea Pigs Eat Peanuts? Quick Guide

Hello everyone, it’s me again, your friendly guinea pig expert! Today, I want to talk about a common question that many guinea pig owners have – can guinea pigs eat peanuts? Well, let’s dive right in and find out!

Peanuts are a beloved snack for humans, but when it comes to our furry little friends, they might not be the best choice. Guinea pigs have special dietary needs, and peanuts don’t quite fit the bill. You see, peanuts are high in fat and carbohydrates, which can lead to some health issues for our precious piggies.

Guinea pigs have a delicate digestive system and require a diet that is low in carbohydrates and high in fiber. Feeding them peanuts can result in obesity, digestive problems, and even choking hazards. Additionally, peanut butter should also be avoided due to its thick and sticky consistency and the added ingredients like sugar and salt.

So, it’s best to steer clear of peanuts and opt for foods that are safe and beneficial for your guinea pigs. But don’t worry, I’ve got you covered on what to feed them instead! Let’s explore safer options that will keep your guinea pig happy and healthy.

The Nutritional Value of Peanuts

When it comes to understanding the nutritional value of peanuts, it’s important to consider their calorie content, protein, carbohydrates, and fat. Peanuts are not only tasty but also nutritious, making them a popular snack choice for many.

For every 3.5 ounces (100 grams) of raw peanuts, you can expect to find approximately 567 calories. Peanuts are a calorie-dense food, so it’s essential to enjoy them in moderation if you’re watching your calorie intake.

In terms of macronutrients, peanuts are a good source of protein, containing about 8 grams per 3.5 ounces (100 grams). Protein is crucial for growth, tissue repair, and overall body function.

When it comes to carbohydrates, peanuts are relatively low, with only 1 gram per 3.5 ounces (100 grams). This makes peanuts a suitable snack option for those following low-carb diets.

Although peanuts do contain fat, it’s important to note that the majority of the fat found in peanuts is healthy fats, such as monounsaturated and polyunsaturated fats. In that same 3.5 ounces (100 grams) serving of peanuts, you’ll find around 2 grams of fat. These healthy fats can have positive effects on heart health when consumed in moderation.

To visually highlight the nutritional value of peanuts, take a look at the table below:

As you can see from the table, peanuts provide a significant amount of calories, protein, and healthy fats while being relatively low in carbohydrates. This makes them a nutrient-dense option for those looking to incorporate them into their diet.

Why Are Peanuts Not Good for Guinea Pigs?

Peanuts may be a beloved snack for humans, but they are not suitable for our furry guinea pig friends. While they may seem harmless, peanuts can have detrimental effects on the health of guinea pigs. Let’s explore why peanuts should be avoided in a guinea pig’s diet.

Peanuts are high in fat and carbohydrates, which are not ideal for guinea pigs. Their digestive systems are designed to process a diet that is low in carbohydrates and high in fiber. Regular consumption of peanuts can lead to obesity, diabetes, diarrhea, GI stasis, and bloat in guinea pigs. These health consequences can significantly impact the well-being of your pet.

Moreover, the size and shape of peanuts pose an additional risk to guinea pigs. They can easily become lodged in their small digestive tract, leading to blockages and potentially fatal consequences. The choking hazard associated with peanuts should not be overlooked.

In order to maintain your guinea pig’s health and happiness, it’s crucial to choose a diet that meets their nutritional needs. Providing them with a balanced and appropriate diet will help ensure their well-being and longevity.

What Should You Avoid Feeding Your Guinea Pig?

In addition to peanuts, it is important to be aware of other foods that guinea pigs should avoid. Here are some examples of foods that are not suitable for guinea pigs:

Nuts and Seeds

Just like peanuts, other nuts and seeds should be avoided as well. These include almonds, cashews, walnuts, and sunflower seeds. Nuts and seeds are high in fat and can cause digestive issues for guinea pigs.

Meat and Dried Fruit

Guinea pigs are herbivores and should not consume meat or dried fruit. These foods can be difficult for guinea pigs to digest and may lead to an upset stomach or even blockages in their digestive tract.

Pellets Made for Other Animals

It is essential to feed guinea pigs pellets specifically made for them. Pellets made for other animals may contain ingredients that are not suitable for guinea pigs and can cause health problems.

Multivitamins (except for vitamin C)

While guinea pigs need vitamin C in their diet, it is important to avoid giving them multivitamins. Multivitamins often contain a combination of vitamins and minerals that may be harmful to guinea pigs.

Unwashed or Spoiled Food

Always make sure to provide fresh and clean food to your guinea pig. Unwashed or spoiled food can harbor bacteria and cause digestive issues.

High-Starch Foods, and Foods High in Fat and Sugar

Foods that are high in starch, fat, and sugar should be avoided, as they can lead to obesity, diabetes, and other health issues in guinea pigs. Examples of such foods include potatoes, sugary treats, and fatty foods.

What Treats Are Safe for Guinea Pigs?

Guinea pigs can enjoy a variety of treats in moderation to supplement their diet. Fruits and vegetables are excellent options for safe and nutritious treats.

The best fruits for guinea pigs include apples, strawberries, and melons. These fruits are not only delicious but also provide essential vitamins and minerals for your furry friend’s well-being.

The best vegetables for guinea pigs are leafy greens such as romaine lettuce and spinach. These greens are rich in fiber and nutrients, promoting a healthy digestive system for your guinea pig.

Treats should make up around 5% of your guinea pig’s diet and should be given once or twice a week. It’s important to offer a balanced variety of fruits and vegetables to ensure your guinea pig receives a diverse range of nutrients.

Remember to introduce treats gradually and in small portions to prevent digestive upset. Always wash fruits and vegetables thoroughly before offering them to your guinea pig.

Providing safe treats for your guinea pig not only adds variety to their diet but also gives them a chance to enjoy different flavors and textures. So go ahead and spoil your furry friend with some tasty and nutritious treats!


After thorough research, it is clear that peanuts and peanut butter should never be a part of a guinea pig’s diet. These foods contain high levels of fat and can lead to various health issues in guinea pigs. To ensure the well-being of these adorable pets, it is crucial to provide them with a balanced diet that is low in carbohydrates and high in fiber.

The main components of a guinea pig’s diet should be hay and grass, which provide essential nutrients and support healthy digestion. In addition to hay and grass, fresh vegetables and fruits can be included as a supplement. However, it is essential to choose safe foods for guinea pigs, avoiding those that are toxic or harmful to their digestive system.

By following these guidelines, guinea pig owners can ensure the optimum health and happiness of their furry friends. Providing a balanced diet, rich in hay, grass, fresh vegetables, and fruits, will contribute to the overall well-being of guinea pigs and help prevent obesity, digestive issues, and other health problems.

Remember, your guinea pig relies on you to make the right food choices. So, let’s stick to safe and healthy options and give our adorable companions the best nutrition they deserve.
