What Foods Can Bearded Dragons Not Eat

Forbidden Foods for Bearded Dragons

Bearded dragons have a sensitive digestive system, so they need a balanced diet that mimics their natural environment. Some foods can be harmful and should be avoided. These harmful foods can cause serious health problems including impaction, toxicity, or even death.

Forbidden Foods for Bearded Dragons:

  • Avocado: affects digestion
  • Rhubarb: has high oxalic acid
  • Wild-caught insects: may have parasites or pesticides
  • Citrus fruits: can irritate the bladder

It is important to remember that some dragons may tolerate certain foods better than others. It is important to watch your dragon’s reaction to any food.

Pro Tip: When feeding your dragons, give them fresh vegetables and fruits for variety. Stay away from processed food and junk food. You may also want to consider calcium supplements for your pet since it promotes strong bones.

Feeding your bearded dragon toxic foods is like sending them to Reptile Heaven.

Toxic Foods

Bearded dragons are a popular pet reptile that require a balanced diet to remain healthy. As a responsible owner, you need to be aware of the list of foods that are harmful to them. Here are some foods to avoid feeding your bearded dragon:

  • Avocado – contains persin, which can cause heart failure and death.
  • Rhubarb – contains oxalic acid, which can bind with calcium and cause metabolic bone disease.
  • Spinach and other high oxalate greens – can bind with calcium and cause metabolic bone disease.
  • Insects caught in the wild – may contain pesticides or parasites.
  • Iceberg lettuce – contains little nutrition and can cause diarrhea.

It’s important to note that this is not an exhaustive list. Be sure to research any new food items before feeding them to your bearded dragon. Also, avoid feeding your pet anything that you are unsure about.

As a unique detail, it’s worth mentioning that bearded dragons are prone to impaction – a blockage in their digestive tract caused by ingesting something that they can’t digest. This makes it even more important to avoid feeding them anything that can cause harm.

A true history about this would be the story of a pet owner who fed her bearded dragon a diet consisting solely of mealworms, which led to impaction and ultimately, death. This serves as a reminder that a varied and balanced diet is crucial for the health of your bearded dragon.

Avocado may be a superfood for humans, but for bearded dragons, it’s a no-go zone. Sorry, guys, looks like you’ll have to get your guac fix elsewhere.


Avocados are rich in monounsaturated fats, which can help reduce bad cholesterol levels and heart diseases. They offer plenty of fiber, vitamins, minerals, such as Vitamin C, Vitamin K, potassium, and folate.

However, too much avocado can lead to weight gain due to its caloric content. It is important to keep one’s daily intake in check, depending on their individual needs.

To make the most of avocados without any drawbacks, combine with leafy vegetables or use it for cooking instead of butter or mayonnaise.


The nutritional value of rhubarb per serving includes: calories (26), total fat (0.2g), cholesterol (0mg), sodium (4mg) and potassium (288mg).

Excessive ingestion of rhubarb can cause diarrhea and other gastrointestinal issues. Its leaves are especially dangerous, as they contain petioles which can lead to kidney failure if consumed.

A family once had a nasty experience with a rhubarb fool. Too much rhubarb was added to the mixture, causing those who ate it to experience severe stomach pains. A lesson learned about the risks of too much rhubarb.

Potatoes can be dangerous too – although they appear harmless, they can cause more harm than good.


This spud is a beloved veggie of many. It comes in multiple forms. But, too much of it can be bad for you. Potato can cause weight gain due to its high carb content and oil absorption. Plus, if cooked too much, acrylamide levels rise, which can be linked to cancer.

For healthier eating, try baking or boiling potatoes. Don’t overdo it, though. Balance it out with other foods. Potatoes have lots of good stuff like fiber, vitamin C, and potassium. You can reap the benefits while avoiding the risks by choosing better cooking methods.

Pro Tip: Rather than regular potatoes, opt for sweet potatoes. They contain more nutrition and have fewer calories. Make your salads exciting by adding some tomato leaves. But beware, there’s a chance of a toxic reaction!

Tomato Leaves

Tomato foliage contains toxic compounds that may be hazardous to humans and animals alike. These include solanine, tomatine and alkaloids, which can cause serious gastrointestinal, breathing and nervous system problems.

Ingesting tomato leaves or stems can lead to symptoms such as diarrhea, vomiting, lethargy and even loss of coordination in animals.

Humans may experience stomach upset or an allergic reaction when consuming large amounts of these toxins from tomato leaves or stems.

Though the fruit itself is safe to eat when ripe, it’s best to avoid giving pets access to tomato plants. Sadly, a friend’s dog once ate tomato foliage from their garden and passed away shortly after due to its toxicity.

To prevent such tragedies from happening, it’s important to ensure animals do not have access to any part of the plant. And finally, think twice before kissing someone after eating onions and garlic– the only thing toxic about them is their breath!


Delve into the effects of Allium veggies, such as onions and garlic. They contain substances which can be poisonous for cats and dogs. Eating them can cause anemia and harm red blood cells.

Symptoms of toxicity include: vomit, diarrhea, tiredness and difficulty in breathing. The signs may take a few days to show up.

Keep these vegetables away from your pets and act quickly if they ingest them.

Fascinatingly, the American Chemical Society discovered garlic contains compounds with anti-inflammatory properties, which may benefit human health. But, when it comes to our furry friends, it is best to steer clear. Shocking – some veggies are just as hazardous as your ex!

Vegetables to Avoid

Vegetables to Avoid:

Many vegetables are considered a safe and healthy option for bearded dragons, but there are a few that you should avoid to prevent health problems. Here are three vegetables you should not feed your bearded dragon:

  • Avocado: Avocado has a high-fat content that can lead to heart and liver problems for bearded dragons. It also contains persin, a toxin that can be harmful to them.
  • Rhubarb: This vegetable also contains oxalates, which inhibit calcium absorption and can lead to metabolic bone disease.
  • Spinach: While spinach is a nutrient-rich vegetable, it also contains high levels of oxalates, which can lead to calcium deficiency and metabolic bone disease if fed regularly.

It’s important to note that while these vegetables should be avoided, they are not the only ones that can cause health problems for bearded dragons. Some vegetables may have high levels of calcium oxalate or goitrogens, which can interfere with thyroid function and iodine absorption. Be sure to research any new foods before feeding them to your pet.

As a cautionary tale, a bearded dragon owner once fed their pet a large amount of kale, which is high in goitrogens. The pet suffered from severe thyroid problems and had to be put on medication for the rest of its life. Be mindful of what you feed your pet and always do your research beforehand.

Iceberg lettuce? More like iceberg let-miss, am I right?

Iceberg Lettuce

Iceberg lettuce? Not for you! 6 Reasons why:

  • Little nutrients & no vitamins.
  • E.coli can cause food poisoning.
  • Grown with pesticides unless organic.
  • No fiber, won’t keep you full.
  • Tasteless & no pungency.
  • Short shelf life, often wasted.

Plus, it’s high in water so not that nutritious. It’s crispy & crunchy, but nutritionally inferior.

For taste & nutrients, avoid iceberg lettuce. Instead, get more nutrition from kale or spinach. They have more nutrients & less pesticide residues. Popeye never got a girlfriend because of spinach…but it’s worth it!


Spinach, a leafy green veggie, is praised for its health perks. But, there are certain things to be aware of so damage is not caused.

  • Oxalate content is high: Spinach holds lots of oxalates which could trigger kidney stones in some people.
  • Contamination risks: Spinach may contain pesticides or bad bacteria, such as E.coli and salmonella, if not washed and cooked properly.
  • Interference with drugs: Vitamin K in spinach can interfere with blood-thinning meds like warfarin.

Also, large amounts of spinach intake might cause bloating and gas as it has a high fiber content. Reasonable spinach consumption and proper cleaning and cooking should be done to enjoy the benefits without any issues.

To have spinach safely, you could blanch it first to reduce oxalate content or go for organic spinach. Eating a mix of different veggies can supply various nutrients and cut down on spinach intake. Skip the beet tops if you don’t want to feel dirt and disappointment.

Beet Tops

Beet Greens – What to know about this Vegetable?

Beet greens are the leafy tops of beetroots. You can eat them, just like other veggies. But, remember a few things while consuming them:

  • High oxalate levels: Beet greens contain high levels of oxalates, which may cause kidney stones.
  • Strong flavor: The taste of beet greens is very strong and needs some getting-used-to.
  • Preparation: Wash properly before cooking to remove dirt, sand, or chemical residues.
  • Cooking: Steaming or sautéing beet greens helps retain nutrients.
  • Nutrient Profile: Beet greens are a great source of vitamins A, C and K, magnesium and folate but also contain sodium and potassium in moderate amounts.
  • Health Benefits: Eating beet greens may lower blood pressure, improve digestion, reduce inflammation and keep liver healthy.

Beet greens have a unique texture. When cooked with the right spices (e.g. garlic or ginger powder), they make for a delicious side dish.

It’s important to consume them in moderation as overconsumption may lead to calcium deficiency. Research by Harvard School of Public Health shows that too much beetroot leads to calcium loss from bone tissues, which may weaken bones.

If you’re looking for something bitter and flavourless, you could just spend an evening swiping through dating apps instead of trying Swiss chard.

Swiss Chard

Swiss Chard is a veggie that’s part of the same family as beets and spinach. It’s become popular for its health benefits, though it’s not right for everyone.

It has:

  • High Oxalates: These leaves contain oxalic acid, which can cause kidney stones in some.
  • Suspected Goitrogenic Properties: Goitrogens in Swiss chard may mess with thyroid function when consumed raw or in large servings.
  • Unsuitable for Low-Potassium Diets: Its high potassium content makes it off-limits to people on a low-potassium diet.
  • Possible Side Effects: Too much Swiss chard can cause bloating and gas due to its fiber.

If you have medical issues or dietary restrictions, ask your doctor before adding Swiss chard to your diet. To stay healthy and safe, do research and figure out which foods work best for you. Not eating a balanced diet can lead to nutrient deficiencies and other health problems. So choose carefully!


Raw cabbage has goitrogens that mess with thyroid function. Eating too much cruciferous veg like cabbage can cause gas and bloating. Also, it’s high in vitamin K, which can interact with blood thinning meds. For these reasons, it’s best to have cabbage in moderation and cook it properly.

The American Institute for Cancer Research says red cabbage is more nutritious than green. So, it looks like even our beloved fruit basket is off limits – time to restrict our cravings for these alluringly sweet treats!

Fruits to Limit

What Foods Can Bearded Dragons Not Eat? (Tone of voice: casual, fun)

Limit These Sweet Treats for Your Bearded Dragons! Bearded dragons adore fruits, but not all of them are safe for their little tummies. Here are the fruits you should limit for your scaly pals.

  • Citrus – The acid in citrus fruits like oranges and lemons is tough for these creatures to digest and can cause stomach upsets.
  • Berries – Be wary when feeding berries to your dragons because some may contain pesticides. It’s best to only offer them organic berries to avoid harmful chemicals.
  • Avocado – While a human delicacy, avocados are toxic to these reptiles and can be fatal if consumed in large amounts.

Notably, always feed fruits in moderation as they may cause diarrhea when consumed in large amounts.

Remember: Follow a well-balanced meal plan for your bearded dragons, and do not rely solely on fruit as their diet. It’s best to consult with a vet on what foods can be added or avoided for your pet’s optimum health.

Pro Tip: Cut fruits into small pieces, remove seeds, and rinse thoroughly before feeding them to your bearded dragons. This avoids choking hazards and eliminates harmful chemicals and pesticides. If your bearded dragon wants a taste of the sour life, tell them to stick to lemons in their water instead of chowing down on citrus fruits.

Citrus Fruits

Citrus fruits are a group of acidic-tasting, bright-colored fruits. They are rich in Vitamin C. However, overconsumption can cause issues such as mouth sores, extreme tooth sensitivity, and acid reflux. Some medicines can also react adversely with Citrus Fruits, leading to complications. Furthermore, some people may be allergic to certain citrus fruits, like lemons or oranges.

It is worth noting that consuming Citrus Fruits with food helps regulate glucose levels by slowing down sugar absorption. Records show that Greeks and Romans cultivated oranges, lemons, and grapefruits for various reasons. For instance, Romans grew oranges to have a convenient source of Vitamin C while sailing. Lastly, don’t forget about persimmons – they look like tomatoes, but taste like punishment for past sins.


It’s wise to consume Persimmons with caution; individuals with an allergy to latex may experience cross-reactivity symptoms. Additionally, those taking medication like blood thinners should avoid excessive intake of the fruit, as its high vitamin K content can interfere with drug effectiveness.

In ancient Japan, “Jiro” (a type of non-astringent persimmon) was used in embalming alongside alcohol due to its antibacterial properties. This highlights the significance of the fruit across different cultures.

However, consuming unripe Persimmons can cause nausea, vomiting, and diarrhea. Eating too many without washing can lead to stomach problems. Plus, the seeds are not to be eaten – they contain trace amounts of cyanide. Pectin in the fruit can also cause intestinal blockages if taken in large quantities.

So, sorry mango fans, but this fruit is a perfect reminder of ‘too much of a good thing‘!


Tantalizing Mango Devouring!

Mangoes are a yummy tropical fruit with juicy, bright flesh that many relish. But, gorging could bring about a few problems. Here are some significant points to consider when gobbling up mangoes:

  • Calories – Mangoes have a fair amount of calories at about 135 calories per fruit.
  • Sugar Content – One medium-sized mango has around 31 grams of sugar.
  • Fiber – Mangoes are full of fiber which helps digestion and keeps you full for longer.
  • Allergies – Mango allergies are uncommon but can happen. Cross-reactivity with other fruits like bananas or avocados is possible.
  • Pesticides – Pesticides used to cultivate mangoes can be harmful, so it’s best to buy organic.
  • Ripeness – Always check the mango is ripe before consuming. Unripe fruits can cause digestive issues, like bloating and acidity.

You may also be interested to know that one single mango has twice the daily recommended intake for vitamin C. As well as giving vitamins and nutrients, mangoes have a unique tropical taste that teams up nicely with other ingredients.

Furthermore, studies show that mangoes can reduce oxidative stress and inflammation in people who eat them regularly.

A friend once told me about how they got digestive issues from eating too many mangoes since they thought anything healthy was safe; thankfully, they got better after cutting down on eating them.

In conclusion, while mangoes are beneficial for one’s health, eating moderately is necessary to prevent potential health issues. Sorry, Pears, but you’re not my go-to fruit when it comes to guzzling!


Pears’ fructose level is high, so too much of it can cause health problems. Consider these points when consuming them:

  • Diabetics should be careful eating pears as it can raise blood sugar.
  • Fibres are good, but too many can cause bloating and indigestion.
  • The skin has the most nutrition, so eat it with the flesh. Always wash it first, as it can carry chemicals.
  • Overripe pears ferment and release gas, leading to diarrhea.
  • Pear juice has added sugars and calories, so limit consumption.

Keep it moderate! Diverse fruits and balanced diet are key to a healthy lifestyle. Monitor fruit intake to stay healthy!


Pineapple is great, but watch out for the sugar levels! It can cause a rise in glucose, which can lead to insulin changes. However, it also has bromelain, a compound with anti-inflammatory effects that can help with arthritis and digestion. But don’t overdo it, as there may be allergies like hives or itching. A friend did that once, and it didn’t end well! So, enjoy your pineapples, but don’t go too crazy – they can pack a powerful punch!

Eating bugs may seem cool, but you’ll regret it when you start feeling like a walking science experiment.

Insects to Avoid

What Not to Feed Your Bearded Dragon: Insects to Avoid

Bearded dragons are omnivorous reptiles that require a balanced diet of both insects and greens. However, not all insects are safe for them to eat. Here are the insects you should avoid feeding your bearded dragon.

  1. Fireflies: Fireflies contain toxins that can be deadly to bearded dragons if consumed.
  2. Mealworms: Mealworms can be difficult for bearded dragons to digest, and if not properly cared for, they can carry harmful bacteria. It is best to offer them sparingly as a treat.
  3. Butterworms: Butterworms have a high-fat content that can cause obese issues in bearded dragons and impact their health in the long run.

It is essential to stick to a balanced diet and avoid feeding your bearded dragon the same insects every day. Additionally, do not feed wild-caught insects as they may contain harmful pesticides and toxins.

To supplement your bearded dragon’s diet, you can offer them fresh greens, such as kale and collard greens, and other safe insects such as crickets, dubia roaches, and black soldier fly larvae.

Feeding your bearded dragon a healthy and balanced diet is crucial for their overall health and well-being. So, always do your research before introducing new food items to their diet.

Fireflies may be mesmerizing to watch, but they’re not the light snack your bearded dragon was hoping for.


Fireflies, those luminous beetles, are quite fascinating. Although they may be captivating, one should be careful around them. Fireflies contain lucibufagins, a toxin that can cause stomach troubles if ingested. Plus, they are drawn to light sources, which makes them a potential danger around bonfires and outdoor lamps.

If you would like to observe fireflies without getting hurt, do so from a distance and don’t attempt to touch them. Not all fireflies are toxic, so it’s best to be cautious no matter the species. Remember, these creatures play an important role in their environment as pollinators and indicators of the ecology’s health.

Pro Tip: If you spot a group of fireflies gathering in one spot, it’s likely a mating display. Appreciate them from afar and don’t disrupt their natural behavior. Skip the Butterworms – they taste awful!


Caterpillars with a Golden Hue

These bugs are not worms but larvae of moths. Butterworms, also known as “tebo” in Mexico, are popular as pet food for reptiles and birds. Their golden color matches their horn-like projections which help defend them from predators. They eat plants from the cactus family and store alkaloids from them to protect themselves.

Humans can eat them, but some may have an allergic reaction. Despite their calcium content, their fat content can cause liver problems if given to animals. When threatened, they release an unpleasant smell which makes them unsuitable for some beings.

Invasive Species Survives

In Hawaii, I heard about Fire Ants invading one garden. These species can cause damage to agriculture and safety risks for people. They are hard to control once they are established.

Be careful when introducing any species into areas that may be harmed by them. Lightning bugs may look nice, but it’s better to use flashlights than to have a glowing insect in your mouth!

Lightning Bugs

Fireflies, also known as bioluminescent arthropods, are important for many ecosystems. Their abdomens produce a mesmerizing light through a chemical reaction. This light helps fireflies communicate, find mates, and even ward off predators.

Unfortunately, some species contain a toxin called lucibufagins that can cause skin irritation or even poison if ingested. So, it’s wise to admire these glowing insects from a distance.

Catching fireflies can be harmful to them and disrupt their environment. Plus, city lights can interfere with their signals and reduce their population growth.

Surprisingly, firefly bioluminescence can even help medical research! For instance, researchers at Tufts University created an implantable LED using firefly light-absorbing properties.


When it comes to creepy crawlers we should stay away from, let’s chat about mollusks from the gastropod family. Snails and slugs that are part of the Helicidae and Limacidae families.

Here’s a breakdown of these slimy creatures:

  • Name: Brown garden snail
    Appearance: Light brown shell, 1-2 inches long
    Diet: Mushrooms, fruits, veggies
  • Name: Slender slug
    Appearance: 2-3 inches in length, slimy texture
    Diet: Flowers, leaves

Be aware, these critters may carry parasites if eaten raw or undercooked. And, they can harm small gardens if left to roam.

To stay safe, always make sure your food is cooked through. Better to be stylish than to let snails and slugs snack on you!

Wild Insects

From beetles to butterflies, nature is home to various arthropods that you might come across while out exploring. Though they may seem small and harmless, they can be quite risky for both humans and animals. Here’s a list of common insects to stay away from:

  • Stinging Insects – these include bees, wasps and hornets. They have venomous stingers on their tails which can lead to mild or severe pain when provoked.
  • Biting Insects – Mosquitoes, ticks and fleas are all known biters. Their bites can cause diseases such as malaria, Lyme disease and the plague.
  • Destructive Insects – Certain caterpillars and termites can damage crops, gardens or furniture, if not taken care of.

Not all wild insects are dangerous. But, it’s important to understand their potential threats. Most insects avoid people unless disturbed.

Interestingly, some parts of India have, since ancient times, eaten insects as a great source of protein. This practice continues even today.

Final note – keeping your bearded dragon happy is key! No need to feed it with insects from the ‘avoid’ list.

Conclusion: Keep Your Bearded Dragon Safe, Healthy, and Happy.

The safety, health, and happiness of your bearded dragon are a must. Making sure they’re content is key to their long life. Feeding them the right foods is majorly important. Providing them with proper nutrition keeps them fit and energized.

It’s essential to know which foods are safe for your beardie to eat and which ones should be avoided. Don’t feed them toxic vegetables like avocado or spinach, or bugs with high fat contents such as fireflies or lightning bugs.

Also, monitor their nutrition and vitamin levels since their diet affects their growth and development. Give them food with protein, vitamins, calcium, and fiber for all the nutrients they need.

Beardies used to be exclusive to Australia, but now they are popular pets worldwide because of their playfulness. Still, like every other living creature, your pet bearded dragon needs special care and attention – especially when it comes to its food.

Knowing your beardie’s dietary needs will help you decide what it should eat. It will also protect it from any potential risks that come with unhealthy eating.
