Water Spinach Vs. Spinach

Since there is a lot of confusion between spinach and water spinach, it becomes essential for you to understand the difference between both vegetables. Watercress and spinach both have excellent nutritional profiles with many similarities.

Carbs and protein are slightly more abundant in spinach. Both leafy green vegetables are made up of 94% water content. However, both greens have wildly varying vitamin contents.

Compared to watercress, spinach has nearly thrice times more contents of vitamin A, five times as much vitamin B5, and higher amounts of folate. Compared to watercress, spinach provides a lot more zinc, iron, and magnesium.

Additionally, spinach has higher quantities of potassium, copper, and sodium. As is already known, both greens are abundant in nutrients such as nitrates, fibers, vitamins, antioxidants, and minerals — all necessary to help a hamster maintain optimal health.

Health Benefits of Water Spinach for Hamsters

Here are a few reasons why incorporating water spinach into your hamster’s diet is a good idea.

Enhance Eyesight and Fur Health

Water spinach has Vitamin A content which is known to improve eyesight. Hamsters have weak eyesight and can only see a few inches from their noses. This makes it essential to feed your hamster food rich in Vitamin A to maintain their eyesight.

Feeding hamsters foods like water and spinach will help you naturally improve and maintain your furry companion’s eyesight.

In addition, you can tell a lot about a hamster’s health by looking at its fur. If a hamster suffers from malnutrition or any other underlying disease, its furs quality will usually reflect that.

Vitamin A helps enhance a hamster’s fur and revive it. So if your rescue hamster has had a few health issues, giving them water spinach is a great way to improve the quality of its fur and make it appear healthier.

Immunity Booster

Vitamin C is essential for a hamster’s immune system health. A hamster with a weak immune system is prone to developing disease and catching illnesses.

Offering a Vitamin C-rich diet to your hamster will help you boost its immune system naturally. If your hamster is recovering from an illness, giving them Vitamin C-rich foods can also speed up their recovery.

Stronger Bones

Rodents like hamsters require calcium to enhance bone health. Hamsters have fragile bones, which may be susceptible to fracturing if their bodies lack calcium.

Giving them small portions of vegetables like water spinach will help ensure their bodies have enough calcium needed to protect their bones from getting damaged with age.

Improves Reproductive Health and Stops Bleeding

Water spinach also contains Vitamin K contents. Vitamin K is known to help improve the reproductive health of hamsters.

Moreover, Vitamin K also has blood clotting properties which help ensure that your furry friend will stop bleeding quickly if they injure themselves.

Even a tiny amount of blood loss can be life-threatening for hamsters. So, if your hamster cut accidentally gets injured, treat it and stop the bleeding immediately.

Therefore, you must feed your hamster a balanced diet with foods rich in minerals, vitamins, and nutrients. Relying on limited treats can cause your hamster to develop vitamin deficiencies.

Before introducing your hamster to a new treat, always contact your vet or conduct thorough research on the internet to ensure that the food item is safe for your breed of hamster to consume.
