Health Benefits of Zucchini for Guinea Pigs

Fresh zucchini contains several essential nutrients (Vitamin A, Vitamin K, C, and Calcium). [1] It’s low in calories, fat, and sugar, making it an excellent food for them.

One cup (223 grams) of cooked zucchini has the following nutritional content:

  • Calories:17
  • Protein:1 gram
  • Fat: less than 1 gram
  • Carbs:3 grams
  • Sugar:1 gram
  • Fiber:1 gram

The above data is from the USDA.

Below are some of the health benefits of feeding zucchini to your guinea pigs:

1. Contributes to Healthy Digestion

Zucchini is high in fiber, which is necessary for a healthy digestive system.

Fiber does a lot for the digestive system, such as preventing constipation, allowing food to move smoothly through the digestive tract, and promoting regular bowel movement.

Guinea pigs fed food high in fiber will rarely have any digestive problems.

2. High in Antioxidants

Zucchini is an excellent source of antioxidants. An antioxidant is a compound obtained from food that will help prevent free radicals from damaging the cells in the body.

Damaged cells can cause cavies to become sick and have diseases.

3. Prevent Scurvy

Scurvy is a disease when cavies are deficient in vitamin C. This disease is common among cavies living in captivity.

Cavies are unable to create and store vitamin C in the body. They will eat it from sources such as food and supplements.

The great thing is that zucchini is an excellent source of vitamin c.

4. Low Sugar Content

Its low sugar content makes it an awesome snack, especially if your pet is overweight or has diabetes.

This is accompanied by high water content, low calories, and low-fat levels. Excess sugar usually leads to health and digestive issues.

5. Healthy Bones and Teeth

The excellent amounts of calcium and phosphorous in zucchini are essential in developing healthy bones and teeth.

Now that you are familiar with the benefits, how do you feed zucchini to your furry pet?
