Can Iguanas Eat Tomatoes? A Complete Guide for Iguana Owners
If you have a pet iguana, you might be wondering what kind of foods you can offer it besides the usual greens and pellets. You might have heard that some fruits and vegetables are good for iguanas, while others are not. But what about tomatoes? Can iguanas eat tomatoes safely? Are tomatoes good for iguanas? How often and how much tomato can you feed your iguana? In this article, we will answer these questions and more, based on the latest research and expert advice.
What are Tomatoes?
Tomatoes are fruits that belong to the nightshade family, along with potatoes, eggplants, peppers, and tobacco. They are native to South America, but have been cultivated and consumed around the world for centuries. Tomatoes come in many varieties, shapes, colors, and sizes, ranging from tiny cherry tomatoes to large beefsteak tomatoes. They are usually red when ripe, but can also be yellow, orange, green, purple, or even black.
Tomatoes are rich in water, fiber, vitamin C, vitamin A, potassium, and antioxidants. They also contain some sugars, acids, and alkaloids. The most notable antioxidant in tomatoes is lycopene, a red pigment that has been linked to many health benefits, including reduced risk of cancer and heart disease.
Can Iguanas Eat Tomatoes?
The short answer is yes, iguanas can eat tomatoes, but only in moderation and with caution. Tomatoes are not a staple food for iguanas, but they can be offered as an occasional treat or as part of a varied diet. Tomatoes can provide some benefits for iguanas if fed in small amounts, such as hydration, vitamin C, vitamin A, potassium, and antioxidants. However, they also have some drawbacks and risks for iguanas if fed too often or too much, such as acidity, sugar, oxalates, and solanine. Therefore, tomatoes should not make up more than 10% of an iguana’s diet, and they should be fed in moderation and with caution.

What are the Benefits of Feeding Tomatoes to Iguanas?
Tomatoes offer valuable nutrients for iguanas that can benefit their health and well-being. Here are some of the advantages of feeding tomatoes to iguanas:
- Hydration: Tomatoes have a high water content (about 95%), which can help keep iguanas hydrated and prevent dehydration. Dehydration can cause many problems for iguanas, such as kidney failure, constipation, impaction, and metabolic bone disease. Therefore, providing your iguana with enough water is essential for its survival.
- Vitamin C: Tomatoes are a good source of vitamin C (about 14 mg per 100 g), which is an essential nutrient and antioxidant for iguanas. Vitamin C helps boost their immune system, prevent scurvy (a disease caused by vitamin C deficiency), heal wounds, and synthesize collagen (a protein that forms the structure of bones, skin, tendons, and ligaments). Vitamin C also helps increase the absorption of iron from plant sources.
- Vitamin A: Tomatoes are a good source of vitamin A (about 833 IU per 100 g), which is an essential nutrient for iguanas. Vitamin A helps maintain their vision (especially in low-light conditions), skin health (preventing dryness and infections), reproduction (ensuring healthy eggs and offspring), and growth (regulating cell division and differentiation). Vitamin A also helps protect against oxidative stress (damage caused by free radicals) and inflammation.
- Potassium: Tomatoes are a good source of potassium (about 237 mg per 100 g), which is an essential mineral for iguanas. Potassium helps regulate their fluid balance (preventing dehydration or edema), nerve function (transmitting signals between the brain and the muscles), muscle contraction (allowing movement and preventing cramps), and heart rate (maintaining a normal rhythm and preventing arrhythmias).
- Antioxidants: Tomatoes are a good source of antioxidants (such as lycopene, beta-carotene, vitamin C, and vitamin E), which help protect iguanas from oxidative stress and inflammation. Oxidative stress and inflammation can cause aging, disease, and tissue damage in iguanas. Antioxidants can help prevent or reduce these effects by neutralizing the free radicals that cause them.
What are the Risks of Feeding Tomatoes to Iguanas?
Tomatoes are not completely safe for iguanas, as they have some potential risks and drawbacks that need to be considered and avoided. Here are some of the main risks and precautions associated with feeding tomatoes to iguanas:
- Acidity: Tomatoes are acidic fruits (with a pH of about 4.3), which can irritate the mouth, throat, stomach, or intestines of iguanas. This can cause inflammation, ulcers, bleeding, or infections in the digestive tract. Acidity can also affect the pH balance of the urine, which can increase the risk of urinary tract infections or bladder stones.
- Sugar: Tomatoes are high in sugar (about 2.6 g per 100 g), which can raise the blood glucose levels of iguanas. This can cause obesity, diabetes, or metabolic syndrome in the long term. Sugar can also feed the growth of harmful bacteria or fungi in the gut, which can cause dysbiosis or gut flora imbalance.
- Oxalates: Tomatoes are high in oxalates (about 5 mg per 100 g), which are compounds that bind to calcium and other minerals in the digestive tract and prevent their absorption. This can cause calcium deficiency or hypocalcemia, which can lead to metabolic bone disease or osteoporosis in iguanas. Oxalates can also form crystals or stones in the kidneys, bladder, or urinary tract, which can cause pain, inflammation, infection, or obstruction.
- Solanine: Tomatoes contain solanine (about 7 mg per 100 g), which is a toxic alkaloid that is found in higher concentrations in the green parts of the tomato plant (such as the leaves, stems, flowers, and unripe fruits). Solanine can cause gastrointestinal distress, neurological problems, liver damage, or heart failure in iguanas if ingested in large amounts.
Precautions While Feeding Tomatoes
- Wash: Always wash tomatoes thoroughly before feeding them to your iguana. This will help remove any dirt, pesticides, herbicides, fungicides, or other contaminants that may harm your iguana.
- Peel: Always peel tomatoes before feeding them to your iguana. This will help reduce the acidity and oxalate content of tomatoes and make them easier to digest.
- Cut: Always cut tomatoes into small pieces before feeding them to your iguana. This will help prevent choking hazards and make them easier to eat.
- Remove: Always remove any seeds or green parts from tomatoes before feeding them to your iguana. This will help avoid any solanine poisoning or oxalate accumulation.
- Mix: Always mix tomatoes with other fruits and vegetables that are safe and suitable for iguanas, such as leafy greens, squash, carrots, apples, bananas, etc. This will help provide a balanced and varied diet for your iguana and prevent any nutritional deficiencies or imbalances.
- Sprinkle: Always sprinkle some calcium or multivitamin supplement on the tomato mixture to enhance its nutritional value and prevent metabolic bone disease or other health problems in your iguana.
- Offer: Always offer the tomato mixture to your iguana in a shallow dish or bowl that is easy to access and clean. Do not leave the tomato mixture in the enclosure for more than an hour, as it may spoil or attract insects or bacteria.
- Observe: Always observe your iguana’s reaction and behavior after feeding them tomatoes and adjust accordingly. If your iguana shows any signs of discomfort, such as vomiting, diarrhea, lethargy, or loss of appetite, stop feeding them tomatoes and consult a veterinarian.
Feeding Different Types of Tomatoes to Iguanas
There are many types of tomatoes available in the market, such as cherry tomatoes, grape tomatoes, plum tomatoes, beefsteak tomatoes, etc. However, not all types of tomatoes are equally suitable for iguanas. Here are some of the main differences and considerations when feeding different types of tomatoes to iguanas:
- Cherry tomatoes: Cherry tomatoes are small, round, and sweet tomatoes that are often eaten whole or in salads. They have a high water content (about 94%), a high sugar content (about 3.9 g per 100 g), and a low oxalate content (about 3 mg per 100 g). Cherry tomatoes are safe for iguanas to eat in moderation, but they should not be fed too often or too much, as they can cause diarrhea or obesity. Cherry tomatoes should be peeled, cut into small pieces, and mixed with other fruits and vegetables before feeding them to your iguana. One or two cherry tomatoes per month are enough for an adult iguana.
- Grape tomatoes: Grape tomatoes are similar to cherry tomatoes, but they are smaller, oval-shaped, and less sweet. They have a high water content (about 94%), a high sugar content (about 3.8 g per 100 g), and a low oxalate content (about 3 mg per 100 g). Grape tomatoes are safe for iguanas to eat in moderation, but they should not be fed too often or too much, as they can cause diarrhea or obesity. Grape tomatoes should be peeled, cut into small pieces, and mixed with other fruits and vegetables before feeding them to your iguana. Two or three grape tomatoes per month are enough for an adult iguana.
- Regular tomatoes: Regular tomatoes are the most common type of tomatoes that are used for cooking or eating raw. They have a medium water content (about 94%), a medium sugar content (about 2.6 g per 100 g), and a medium oxalate content (about 5 mg per 100 g). Regular tomatoes are safe for iguanas to eat in moderation, but they should not be fed too often or too much, as they can cause acidity or oxalate problems. Regular tomatoes should be peeled, cut into small pieces, and mixed with other fruits and vegetables before feeding them to your iguana. A quarter of a regular tomato per month is enough for an adult iguana.
- Green tomatoes: Green tomatoes are unripe regular tomatoes that are sometimes used for frying or pickling. They have a low water content (about 93%), a low sugar content (about 1.9 g per 100 g), and a high oxalate content (about 8 mg per 100 g). Green tomatoes also contain solanine (about 11 mg per 100 g), which is a toxic alkaloid that can cause gastrointestinal distress or neurological problems in iguanas. Green tomatoes are not safe for iguanas to eat and should be avoided at all costs.
Can Iguanas Eat Tomato Seeds or Leaves?
Tomato seeds and leaves are not safe for iguanas to eat and should be removed before feeding them any part of the tomato fruit. Tomato seeds contain solanine (about 15 mg per 100 g), which is a toxic alkaloid that can cause gastrointestinal distress or neurological problems in iguanas. Tomato seeds also contain oxalates (about 10 mg per 100 g), which can bind to calcium and other minerals and prevent their absorption. Tomato leaves contain even more solanine (about 136 mg per 100 g) and oxalates (about 25 mg per 100 g) than tomato seeds, and they can also irritate the mouth or throat of iguanas. Tomato leaves also contain nitrates (about 2000 mg per kg), which can convert to nitrites in the body and cause methemoglobinemia or blood poisoning in iguanas.
