Are Grapes Good for Guinea Pigs? | Health Benefits

Are Grapes Good for Guinea Pigs

There are a lot of benefits that a guinea pig can get from eating grapes. The following are just some of the main health benefits of grapes for guinea pigs:


• Vitamin C

It is a fact that cavies cannot produce vitamin C naturally on their own. For this reason, they need it from external sources. This vitamin is vital for guinea pigs. Vitamin C helps to prevent a disease called scurvy which is a condition that affects guinea pigs.


• Provides Energy for the Guinea Pigs

Grapes can give your cavy the power it needs for all the activities throughout the day with the provision of vitamin B6.


• Eliminates Free Radicals

Grapes are rich in antioxidants that will ensure there are no free radicals in the body of your guinea pig. This boosts its health and life span. They also help to patch up any damage done by free radicals to the body cells. The antioxidants are mainly concentrated in the skin and seeds of a grape.


• Helps in Sustaining Optimal Heart Health

A healthy heart means a healthy guinea pig. If your guinea pig starts suffering from heart-related conditions, then this can potentially be fatal. And that is why you need to fix the situation early. After all, prevention is better than a cure. Potassium that is found in grapes helps to maintain the blood pressure at optimum levels.


• Aid in the Reduction of Cholesterol Levels in the Body

Cholesterol is harmful to guinea pigs just as it is to humans. The nutrients that are present in grapes help with getting rid of the cholesterol in cavies.


• Grapes Can Help to Decrease Blood Sugar Levels

As strange as this may sound, this is a proven medical fact. As much as grapes are high in sugar, they have a low glycemic index, which is a measurement used to indicate how fast a portion of food can raise the blood sugar levels.


• Good for Eye Health

Many people assume that only carrots help to maintain good eyesight, right? But grapes also have amazing potential to boost eye health. The nutrients present in grapes can guard against eye defects and complications.


• Grapes Can Improve Bone Health

The minerals such as magnesium, calcium, potassium, and manganese help the cavy to have a healthy and sturdy bone structure. Studies have also shown that resveratrol found in grapes improves bone density.


• Protects the Cavy Against Infections and Diseases

There are compounds found in grapes that have the potential to protect your guinea pig against bacterial, viral, and yeast infections. This is why you need to feed grapes to guinea pigs regularly. Again, vitamin C that is found in grapes helps to boost immune function in the guinea pig’s body.


• Boosts the Guinea Pigs’ Lifespan

The nutrients found in grapes are said to increase longevity and overall lifespan of guinea pigs.


• Prevents Inflammation

Resveratrol that is found inside the grapes has excellent anti-inflammatory properties.


• Prevents Constipation and Helps With Digestion

Since grapes have both water and dietary fiber in them, they help during the digestion process and also ease the bowels.


• Helps With Allergies

Due to the anti-inflammatory properties of this fruit, it is believed that grapes help with alleviating different allergies.
