Delicious both fresh and raw as well as steamed or cooked into a casserole, green beans are a favorite summertime food for humans. But can your guinea pig enjoy these crispy treats along with you?
In short, yes, guinea pigs can eat green beans. In fact, when fed in appropriate amounts, green beans, and their peels can provide significant health benefits for your guinea pig. This does not mean, however, that you’ll want to make them a daily addition to your cavy’s diet.
If you’re keen on sharing fresh green beans with your guinea pig, keep reading to discover why they can be a great supplement to your piggy’s diet as well as how they can become dangerous if fed too often.
Nutritional Information on Green Beans for Guinea Pigs
Just like us humans, guinea pigs are unable to create their own vitamin C within their bodies and must get it from outside sources. Adult guinea pigs need anywhere from 20 to 25 mg/day of vitamin C, and for pregnant guinea pigs, this requirement jumps up to 30 to 40 mg/day.
While green beans contain some vitamin C, it is unrealistic to expect a guinea pig to obtain all they need from this source. It would take a large amount of raw green beans for your guinea pig to get what they need of this nutrient. There are only about 12 mg of vitamin C in 100 grams of green beans. Feeding such large amounts of green beans to a guinea pig is not recommended. Remember that your guinea pig’s diet should primarily consist of hay, supplemented with some leafy greens, pellets, safe veggies, and the occasional fruit treat.
Additionally, green beans are high in vitamin K, a nutrient that’s valuable in regulating blood clotting and preventing blood loss after injury. While there is no recommended intake requirement for vitamin K in guinea pigs, green beans provide a solid 43 micrograms per 100-gram serving.
Additionally, green beans are a source of plant-derived protein and fiber, both of which are important parts of a guinea pig’s diet.
Can Green Beans Be Bad for Guinea Pigs?
While green beans can offer some nutritional benefits for your guinea pig, they also pose two potential problems:
- Excessive phosphorus. Guinea pigs’ organ systems need a specific balance of calcium, phosphorus, potassium, and magnesium. Since green beans contain a significant portion of phosphorus, overfeeding your guinea pig with this vegetable can negatively impact the health of their kidneys and bladder.
- Digestive issues. Green beans are in the legume family, a category well-known for their ability to cause flatulence and indigestion. Their high fiber offsets this somewhat, however, overfeeding green beans can still lead to painful indigestion for your cavy.
How to Feed Green Beans to Your Guinea Pigs
Choosing fresh, organic green beans is essential to maintaining your guinea pig’s health. Never attempt to feed green beans that haven’t been organically grown to your guinea pig, as they can be filled with harmful waxes and pesticides at concentrations that are dangerous for small animals.
Instead, feed whole organic green beans to your guinea pig. The shells are very rich in fiber, which will help your pet to properly digest their meals. One or two whole beans are more than enough for a single serving for your guinea pig. It is also best to choose younger green beans over larger and more mature ones.
Can Guinea Pigs Eat Cooked Green Beans?
Guinea pigs absolutely cannot eat cooked green beans. Like many other small animals, guinea pigs thrive on a diet of fresh, uncooked foods. Introducing processed or cooked foods would cause them serious gastrointestinal distress. Thankfully, most guinea pigs will turn their nose up at cooked food rather than try to eat it in the first place.
How Often Should I Feed My Guinea Pig Green Beans?
Finding the right balance for your guinea pig’s diet can be tough with green beans, as they have the potential to be both helpful and harmful. We recommend introducing green beans into your cavy’s diet slowly and monitoring closely for signs of indigestion such as bloating or diarrhea.
If they handle these initial feedings well, it’s safe to feed a small portion of green beans as a supplement to your guinea pig’s diet anywhere from one to three times per week.
Final Thoughts
A valuable addition to your guinea pig’s diet when fed in moderation, green beans can help to provide some variability to their diet while providing a little bit of vitamin C and some fiber as well. If overfed, they run the risk of producing problems for your cavy’s digestion and mineral metabolism.
Keep green beans only as an occasional supplement to your guinea pig’s hay and pellets diet, and they’ll enjoy all of the benefits with none of the problematic side effects.
