For the ardent reptile aficionados wondering if bearded dragons can eat sweet peppers, the answer is yes, but with a caveat. Bearded dragons, fondly known as beardies, can indeed consume sweet peppers, but the servings should be kept minimal. This tasty beardie treat is best offered maybe once or twice per month.

Sweet peppers, also referred to as bell peppers, carry a high concentration of oxalates 1, which can pose certain health risks if consumed excessively. Although all bell peppers are relatively safe for healthy beardies, green and yellow bell peppers are purportedly preferred over red ones for their nutritional profile.

Nutritional Composition of Bell Peppers

Understanding the nutritional profile of bell peppers helps in determining their suitability for your beardie’s diet. Here is a snapshot of what 100 grams of raw green bell peppers contain:

Calories: 20 Cal
Water Content: 93.89 grams
Carbohydrates: 4.64 grams
Sugars: 2.4 grams
Fat: 0.17 grams
Proteins: 0.86 grams
Calcium: 10 milligrams
Phosphorus: 20 milligrams
Sodium: 3 milligrams
Vitamin A: 370 International Units (IU)
Vitamin C: 80.4 milligrams
Oxalates: 117 milligrams

A comparison of the nutritional values reveals that all bell peppers share a similar nutritional composition. However, red peppers significantly stand out due to their higher vitamin A content.

Focus Areas: Vitamin A and Oxalates

When feeding bell peppers to bearded dragons, two key nutrients to be mindful of are vitamin A and oxalates.

Vitamin A

Green and yellow bell peppers contain relatively safe levels of vitamin A (200–370 IU), while red bell peppers have a substantially higher content (3,131 IU). However, this should not cause undue concern unless you’re supplementing your beardie’s diet with vitamin A retinoids.

Most reptile supplements use beta-carotene, a natural form of vitamin A found in bell peppers. The body excretes any surplus beta-carotene through urine. Contrastingly, human supplements often contain retinoids, a synthetic form of vitamin A that the body has to absorb. This could lead to vitamin A toxicity if combined with high-vitamin-A foods like red bell peppers.

High Oxalates

Oxalates bind with calcium, hindering its absorption. Regularly feeding your beardie foods high in oxalates could potentially deplete their calcium levels. Given that 100 grams of bell peppers contain over 100 milligrams of oxalates, which is considered high, it’s best to limit the pepper portion!

Understanding the Calcium-to-Phosphorus Ratio

Green and yellow bell peppers contain twice as much phosphorus as calcium, while red bell peppers contain three times more phosphorus than calcium. This isn’t ideal, as phosphorus impedes calcium absorption. One way to counterbalance this is to serve bell peppers alongside calcium-rich foods.

Serving Bell Peppers to Bearded Dragons

Preparing and serving bell peppers to bearded dragons is a straightforward process. Remember, due to their high phosphorus and oxalate content, bell peppers should be offered sparingly—once or twice per month, at most.

To prepare, remove the top and all seeds from the pepper. Cut it into rings; each ring from a medium-sized pepper weighs approximately 10 grams. Since high oxalate levels pose a concern, limit the serving to 10 grams, or one ring, per feed. Cut the ring into smaller strips, each no larger than the distance between your beardie’s eyes. Mix these strips with other high-calcium foods and serve at room temperature to ensure a balanced meal.

In conclusion, sweet peppers can add a splash of color and variety to your bearded dragon’s diet. They are safe to eat but should be given with extreme care, considering their high oxalate content and less-than-ideal calcium-to-phosphorus ratio. Always strive for a balanced diet to keep your scaly friend healthy and happy!
