Iguana Cuisine: A Guide to Their Favorite Foods

When it comes to the culinary preferences of iguanas, one might be surprised to learn that they have quite the discerning palate. Iguanas are herbivores, meaning they feast on a diet rich in fruits, vegetables, and leafy greens. But, like a food critic at a five-star restaurant, they have their favorites and their no-thank-yous. Let's dive into the world of iguana cuisine, where the salad bar is always open and the main course is always green.

The Basics of Iguana Diet

What Iguanas Eat

Iguanas are strict vegetarians. This means that their diet consists of a variety of fruits, vegetables, and leafy greens. They are particularly fond of foods that are high in calcium, such as collard greens, mustard greens, and dandelion leaves. However, they also enjoy a variety of fruits, including bananas, apples, and strawberries.

While iguanas do enjoy a good fruit salad, it's important to note that fruits should make up only a small portion of their diet. Too much fruit can lead to health problems, such as diarrhea and vitamin imbalances. So, while an apple a day might keep the doctor away for humans, for iguanas, it's more like an apple a week.

What Iguanas Don't Eat

Just as important as knowing what to feed your iguana is knowing what not to feed them. Iguanas have a very specific dietary needs and certain foods can be harmful or even fatal to them. For example, they should never be fed animal protein, such as meat or dairy products. These foods are too high in protein and can cause serious health problems for iguanas.

Other foods to avoid include lettuce, spinach, and broccoli. While these might seem like healthy options, they actually contain chemicals that can interfere with an iguana's ability to absorb calcium. This can lead to a condition known as metabolic bone disease, which is a common health problem in pet iguanas.

Feeding Your Iguana

How Often to Feed

Young iguanas have a fast metabolism and need to eat daily. As they grow older, their metabolism slows down and they can be fed every other day. However, it's important to monitor your iguana's weight and adjust their feeding schedule as needed. If your iguana is losing weight or seems hungry all the time, you may need to feed them more often.

It's also important to feed your iguana at the right time of day. Iguanas are diurnal, which means they are most active during the day. Therefore, it's best to feed your iguana in the morning or early afternoon.

How Much to Feed

The amount of food your iguana needs will depend on their age, size, and health. A good rule of thumb is to provide a pile of food that is about the same size as your iguana's body, excluding their tail. This should be enough to satisfy their hunger without overfeeding them.

Remember, it's better to provide too much food than not enough. If your iguana is consistently leaving food behind, you can always reduce the amount you're offering. But if they're always finishing their food and still seem hungry, it's a good idea to offer more.


Can Iguanas Eat Insects?

While some reptiles are insectivores, iguanas are not. They are strict herbivores and their digestive system is not equipped to handle animal protein. Feeding your iguana insects can lead to serious health problems.

Why is My Iguana Not Eating?

There could be several reasons why your iguana is not eating. They could be sick, stressed, or they might not like the food you're offering. If your iguana is refusing to eat, it's a good idea to consult with a vet.

Can Iguanas Eat Human Food?

While iguanas can eat some of the same fruits and vegetables that humans do, it's important to remember that their nutritional needs are not the same as ours. Always consult with a vet before introducing new foods into your iguana's diet.


Feeding your iguana a balanced and varied diet is crucial for their health and well-being. By understanding their dietary needs and preferences, you can ensure that your iguana is getting the nutrition they need to thrive. Remember, when it comes to iguana cuisine, the greener the better!
