Most people who pet guinea pigs wonder whether guinea pigs, these cute small animals, can eat green beans.

Guinea pigs can eat green beans, and they are a great addition to their diet because they contain many essential vitamins and minerals such as vitamin A, vitamin K, vitamin C, iron, magnesium, phosphorus, potassium, zinc, copper, but also calcium, which is not such a great thing for guinea pigs. Nonetheless, feeding guinea pigs with green beans in moderation one to three times a week is a great choice.

As herbivores, guinea pigs eat fresh vegetables and fruits, but not all are equally beneficial for their health.

Guinea pigs need an unlimited supply of timothy hay and fresh and clean water every day, as well as natural food rich in vitamin C.

To keep your pet healthy, you should know which nutrients they should eat, which foods are dangerous to them, as well as the amount of food they should consume every day.

green beans choppedGreen beans, otherwise called string beans, are a staple food in numerous dishes around the world.

With loads of medical advantages for humans, people assume that green beans are good for animals as well.

Guinea pigs need to eat food that is rich in vitamin C, as they can not synthesize this nutrient.

For that reason, there is a variety of manufactured guinea pig foods high in vitamin C.

Can Guinea Pigs Eat Green Beans Every Day?

Guinea pigs can eat green beans one to three times a week.

However, a healthy guinea pig’s diet rests on an equilibrium of hay, guinea pig pellets, and fresh and raw fruits and vegetables.

Just like people, guinea pigs can’t make their own vitamin C, so they require vitamin C-rich nourishments in their everyday diet.

Green beans are plentiful in Vitamin C, fiber, and other fundamental supplements, which are indispensable for every guinea pig.

In any case, green beans are high in oxalic corrosive and calcium, which can prompt illnesses in guinea pigs.

So, since you can feed your guinea pig green beans, let’s understand the dietary benefits of this vegetable and how acceptable it is for our guinea pigs.

Note that a guinea pig might love green beans, that doesn’t imply that all guinea pigs eat this vegetable with equal delight.

Some guinea pigs may love this food, while others may dislike it.

However, that is expected because guinea pigs are fussy about food.

As already said, a guinea pig’s healthy daily diet consists of large quantities of hay and small quantities of fruits and vegetables.

Feed your guinea pig green with beans 1-3 times per week.

Pay attention to the amount of food that you give to your guinea pig pet.

Never give your guinea pig more than one to two strings of green beans at a time.

The nutritional value of green beans may give you the feeling that guinea pigs can eat green beans regularly.

Yet, that is not the case as green beans also contain substances that can endanger your pet’s wellbeing.

Are There Dangers to Feeding a Guinea Pig With Green Beans?

Green beans are a good source of vitamin C, fiber, and other essential nutrients for guinea pigs when served in limited quantities.

Feeding your guinea pig green beans or any other food without control leads to health problems that can seriously endanger your guinea pig.

Green Beans Can Cause Bladder Stones

Green beans are hazardous when in contact with another compound called oxalates, as these draw in calcium.

At the point when calcium and oxalates are available, they structure little gems, otherwise called stones.

This is the thing that causes kidney and bladder stones, and where they get their name.

Calcium is one of the most perilous minerals for guinea pigs.

As it’s in numerous nourishments, it is difficult to avoid it completely.

Green beans contain 37 mg of calcium per 100 grams.

Additionally, they contain 16.3 mg of vitamin C per 100 gr.

For that reason, even if you give your guinea pig 100g of green beans (a full cup), it still wouldn’t meet the required amount of vitamin C that your pet needs daily.

An average guinea pig needs around 30mg/kg of vitamin C per day.

Oxalates are found in many plant nourishments.

Nonetheless, the amount of calcium and oxalates together may be troublesome for guinea pigs, if taken in large quantities.

Digestive Issues

Green beans are useful for digestion as they contain a high measure of fiber.

Fiber is great for guinea pigs and one of the essential nutrients for this small animal.

Yet, feeding your guinea pig with large quantities of any fruits and vegetables leads to trouble.

Guinea pigs have a sensitive digestive system and can easily suffer from diarrhea.

Additionally, green beans contain sugar that guinea pigs can’t process well.

Consequently, foods that contain sugar can cause gastrointestinal issues in guinea pigs.

Lectins are a protein, found in most types of beans, including green beans.

This means your guinea pig can experience the ill effects of clogging or swelling from eating green beans.

The lone strategy to diminish the number of lectins is to cook them.

However, that is impractical as guinea pigs can’t eat cooked foods.

Restrict the number of green beans and never feed your guinea pig with more than one to two strings of raw and fresh green beans per serving.

Therefore, serving green beans in the right quantity is beneficial.

Besides, you should mix low calcium vegetables with green beans to prevent your guinea pig from eating too much calcium per serving.

Vegetables such as bell peppers, lettuce, and so forth are a great source of nutrients and vitamin C for your guinea pig.

Heart Health

Green beans contain potassium and fiber that control the pulse, which decreases the danger of coronary illness or stroke.

Another incredible point towards your guinea pig’s well-being is low sodium, as green beans contain just 6mg of sodium per 100 grams.

That is acceptable as sodium expands circulatory strain and holds more water, which causes swelling.


With green beans, there is no danger of the guinea pig getting plump or stout.

Green beans are vegetables low in calories, carbs, proteins, and fats.

At the point when these supplements are in limited quantities, the heaviness of your guinea pig won’t be influenced.

Cancer Prevention Agent

Green beans will furnish your guinea pig with a great measure of cancer prevention agents.

Cancer prevention agents eliminate the free radicals and the harm they cause (early maturing and ongoing illnesses).

Green beans have Vitamin A, manganese, and selenium, which are the best and most grounded cell reinforcements that are also beneficial for your guinea pig’s health.

Great for Eyesight

The same happens to guinea pigs.

Green beans contain nutrients that secure against age-related decreases.

However, you should know that scientists have found that a guinea pig diet should contain between 6 and 7 mg of vitamin A/kg, as this amount meets the daily requirement of growing guinea pigs.

Generally, 30 g of food consumed daily contains an equivalent of 0.2 mg of vitamin A, which confirms previous findings.

High In Vitamin C

Possibly the most fundamental nutrient in your guinea pig’s eating regimen is vitamin C, and green beans contain a great deal of this.

Indeed, guinea pigs need 25-40mg of Vitamin C daily, since they can not synthesize it themselves.

So shouldn’t something be said about green beans?

So you can really improve the soundness of your guinea pig by serving them green beans ever so often.

Green beans are likewise low in fat, which is an additional benefit.

What is the Nutritional Value of Green Beans?

Note: The accompanying rundown is estimated per 100 grams of Green Beans.

Sugar content is 3.3 grams, which is genuinely low contrasted with numerous different nourishments.

Fiber is 3.4 grams, which means there is more fiber than sugar.

This is incredible because it helps in nutrient absorption, and the sugar is delivered slower in the circulation system.

Sodium, otherwise called salt, is extremely low.

It just contains 6mg of sodium, decreasing the chance of swelling in your guinea pig.

Potassium is genuinely high with 209mg, protein is 1.8 grams, and that probably won’t seem like a ton, however, your little pal just needs a smidgen, so this is a decent number.

Calcium is somewhat high at 37mg, which can cause bladder stones whenever taken in abundance.
