Red Tomatoes (raw)Per 100g Serving
Areas of Concern
Tomatoes may seem like a healthy choice, but you should be aware of the following issues:High Oxalates
Tomatoes contain 26mg of oxalates per 100g serving. Ideally you want each meal to have no more than 10mg of oxalates as they prevent calcium from being absorbed.High Acid Levels
Tomatoes are acidic. Raw tomatoes have an average PH values around 4.5 which can cause mouth and stomach irritation in bearded dragons.Poor Calcium to Phosphorus Ratio
Tomatoes have twice as much phosphorus than calcium. This is not good because phosphorus blocks calcium from being absorbed. Ideally you want more calcium than phosphorus, this way any remaining calcium will be absorbed by the bearded dragon. Since tomatoes have a higher level of phosphorus this means calcium will be blocked from other foods in their diet.
