Bearded dragons can eat tomatoes, but only in small quantities and occasionally. Tomatoes contain vitamins A and C, which are beneficial for bearded dragons. However, they also have a high acidic content and a poor calcium-to-phosphorus ratio, which can be problematic if consumed in large amounts. Excessive intake of phosphorus can interfere with calcium absorption, leading to potential health issues like metabolic bone disease. When offering tomatoes, it's best to choose ripe ones and remove the seeds, as these can be difficult to digest. Always wash tomatoes thoroughly to remove pesticides. Given their acidity and nutrient imbalance, tomatoes should not be a staple in a bearded dragon's diet. Instead, they should be part of a diverse diet that includes a variety of leafy greens, vegetables, and insects. For specific dietary advice, consult a veterinarian experienced with reptiles to ensure the overall health and well-being of your bearded dragon.
