Can Bearded Dragons Eat Corn?

Bearded dragons can eat corn. However, due to its high content of phosphorus, corn should only be fed to bearded dragons on rare occasions. If fed in excess, corn can lead to serious health diseases in bearded dragons.

This is a summary of what we’ll be covering in today’s post and it’s meant to help you make an idea of what you should expect from this blog post.

If there’s one thing I know for sure is that you’ll learn anything there is to know about the topic only by reading this article, so make sure you bear with me till the end.

Nutrition in Corn

100 Grams of Fresh Corn contain the following:

Nutrients in CornAmount
Vitamin C6.8mg/100g
Vitamin A187 IU
Ca:P Ratio1:45

I can see some VERY interesting things about corn just by looking at the table above.

For example, the one thing that really stands out is the calcium to phosphorus ratio. The Ca:P ratio in corn is 1:45, meaning that we have 45 times more phosphorus than calcium in 100g of corn.

As you probably already know, bearded dragons need foods that have a decent calcium to phosphorus ratio, and everything extremely negative should be avoided.

The most important thing is to make sure you don’t feed your dragon foods rich in phosphorus too often. Failure in providing your lizard with a balanced diet and the right foods can lead to calcium deficiency or Metabolic Bone Disease [MBD]Opens in a new tab., which is one of the most common and dangerous diseases in captive reptiles.

Can Bearded Dragons Eat Corn?

Well yeah, bearded dragons can eat corn, but as previously mentioned corn should only be fed to dragons on rare occasions.

We’ll discuss more about it later on and I’ll explain why corn shouldn’t be fed to dragons as staple food.

They can eat sweet corn or corn on the cob as well, but the same rule applies. Feed any type of corn in moderation and limited portion.

As for canned corn or cooked corn, well, I’d just stay away from cooked or canned foods altogether.

Generally, bearded dragons should only be fed fresh foods that are rich in nutrients and have a stable/positive calcium to phosphorus ratio.

Is Corn Good For Bearded Dragons? Or Is It Bad?

Corn has some important nutrients in it. There’s no question about it.

But if there’s a thing I learned really fast about bearded dragons is that what’s amazingly nutritious and beneficial to humans doesn’t have to be as nutritious and beneficial to dragons.

It doesn’t work like that.

In fact, a good example, just to prove my theory is spinach. Spinach, frozen, fresh or cooked, is really healthy for humans.

At the same time, feeding spinach to a dragon can cause him to get sick and can lead to a variety of diseases that are better to be avoided.

On the other hand, corn is indeed full of a variety of nutrients and minerals, but is it a GREAT food for bearded dragons?

No. Not really.

How OFTEN Can Dragons Eat Corn?

I’ll try to keep it simple here.

I believe that feeding your dragon corn once a month and in limited portion is considered to be safe.

I’d make sure any possible chemicals are removed prior to feeding. If served foods that have traces of chemicals on their skin can lead to dehydration and diarrheaOpens in a new tab. in bearded dragons.


I really hope you learned a few things from today’s post. If you did and these things you learned will help you better care for your dragon, then my mission is accomplished.

Let’s recap.

  • Bearded dragons can eat corn or sweet corn.
  • Bearded dragons shouldn’t be fed canned or cooked corn.
  • Corn should be fed to dragons on rare occasions and limited portion. Specifically, if you really want to do it, only feed corn to your lizard once a month.
  • You need to wash it prior to feeding to ensure any chemicals are removed.
  • Corn shouldn’t be fed too often as it is HIGH in phosphorus and can lead to calcium deficiency and Metabolic Bone Disease in bearded dragons if fed too often.

Here’s a list of other veggies bearded dragons will happily feed on.

Carrots, Tomatoes, Celery [Stalk & Leaves], Cucumbers, Cabbage, Kale, Zucchini: Okay to feed occasionally

You should avoid feeding Mushrooms, Avocado’s, Lettuce, Eggplant or Onions to your lizard.

Can Bearded Dragons Eat Cauliflower? Well, yeah. Bearded dragons can eat cauliflower but they shouldn’t have too much of it though. Cauliflower is not staple in a dragon’s diet and should only be fed in small bits and pieces from time to time.

Can Bearded Dragons Eat Nectarines? Occasionally. Nectarines have a disproportionate calcium to phosphorus ratio as well as high acidity, meaning that bearded dragons can eat them but only small bits and pieces and on an occasional basis. If I were you, I’d go for other fruits they like more such as apples, grapes, raspberries, watermelon or blueberries.
