Health Benefits of Guinea Pigs Eating Leeks

As much as leeks can only be used in limited proportions and are in the end not recommended for the guinea pig diet, they sure have some advantages that are good for the guinea pigs. The following are some benefits of the leeks:

  • They are essential for bone health. Vitamin K found in leeks has some significant advantage when it comes to boosting bone health.


  • Leeks help in maintaining cardiovascular health. The importance of the heart cannot be overemphasized as it is an integral part of the body. Leeks have shown the presence of folate which can prevent and reduce cardiovascular-related diseases.


  • It reduces inflammation often brought about by diseases, infections or injuries. When it is not handled correctly, it can become chronic and thus cause further complications for your little pet.


  • Boosts digestion process. The presence of dietary fiber in leeks enables your guinea pig to have a smooth digestive process. Dietary fiber also acts as a filler to prevent overeating which in the long run reduces the number of calories taken into the cavy’s body. In addition to all that, fiber also helps to reduce the chances of constipation and other stomach related issues.


  • It may aid in weight loss. Although this is yet to be confirmed fully, leeks are said to have the ability to foster weight loss and control in guinea pigs. First of all, they achieve this by acting as a filler food, meaning that your guinea pig won’t overeat after ingesting leeks. This reduces the number of calories taken into the body thus controlling weight. The other reason why they are an ideal weight loss plan is the fact that they are low in calories and have little to no fat. Since they act as an appetite suppressant, you need to give them to your pet only a few times to avoid malnutrition.


  • It improves sight and vision. Lutein and zeaxanthin present in leeks are known nutrients that help with a view and image processing in our brains. These compounds prevent any harmful elements that can affect the eyes and destroy vision.


  • Regulates the level of cholesterol in the body. Cholesterol is a toxic compound found in the body and it can have severe effects on the heart if not taken care of.
