Nutritional Value Of Tomatoes
Here is the nutritional value of 100g of raw red tomatoes per the USDA.
- Water: 94.5 g
- Carbohydrates: 3.89 g
- Sugars: 2.63 g
- Fat: 0.2 g
- Protein: 0.88 g
- Fiber: 1.2 g

When it comes to the nutritional punch tomatoes pack, it’s quite impressive, and not just for us humans! These vibrant red fruits are loaded with vitamins and antioxidants, making them a tempting option for a turtle treat. Tomatoes are rich in vitamins C, K, potassium, and folate, among other nutrients.
They’re also a source of antioxidants like lycopene, which can help protect your turtle’s cells from damage. Plus, the high water content in tomatoes can be a refreshing way to help keep your turtle hydrated, especially during those warmer months.
Potential Risks Of Feeding Tomatoes To Turtles
Acidity
Tomatoes have a natural acidity that can be a double-edged sword for turtles. This acidity, primarily due to malic and citric acids, is tolerable for humans but can be harsh on a turtle’s more sensitive digestive system.
Imagine indulging in a spicy or acidic meal and the discomfort that sometimes follows; turtles can experience a similar reaction. Their digestive tracts are not designed to handle high levels of acidity regularly, which can lead to discomfort, irritation, or even more severe digestive issues over time.
Calcium To Phosphorus Ratio
Turtles, especially growing ones, need a diet with a 2:1 ratio of calcium to phosphorus to support healthy shell and bone development. Tomatoes, however, tip the scale in the opposite direction, offering more phosphorus than calcium. This imbalance can lead to metabolic bone disease, a serious condition that weakens a turtle’s shell and skeletal structure over time.
It’s crucial to balance out the occasional tomato treat with foods high in calcium, like dark leafy greens or calcium supplements specifically designed for reptiles, to maintain that critical balance.
Sugar Content
Turtles, especially in captivity, can easily become overweight if their diet isn’t managed properly. And here’s where the sugar content in tomatoes comes into play. While not excessively high, the sugars in tomatoes can contribute to weight gain if fed in large quantities. It’s similar to how we enjoy sweet treats; a little is fine, but too much can lead to health issues.
Oxalates
While offering a burst of flavor and hydration, tomatoes bring oxalates to the table. To put it in perspective, one medium-sized tomato contains about 7mg of oxalates. While this amount might seem minimal, every milligram counts in the grand scheme of a turtle’s diet.
Think of oxalates as tiny nutritional gatekeepers, holding onto calcium and preventing it from being absorbed into your turtle’s system. When oxalates enter the scene, they can bind to calcium, creating complexes the body can’t use, effectively sidelining this crucial mineral.
How To Prepare Tomatoes For Turtles?
First, always opt for ripe, organic tomatoes to minimize the risk of pesticide exposure. These chemicals can harm your turtle, so it’s better to play it safe. Whether organic or not, thoroughly wash those tomatoes under running water to remove any surface residues.
Serving a small wedge or a few bite-sized pieces will keep things in check. This way, you’re keeping the oxalate intake low while letting your turtle enjoy the juicy goodness of tomatoes.
While seeds are safe, you can remove them and the inner juicy part of the tomato to reduce the sugar and acid intake. The fleshy part of the tomato is what you’re aiming for, as it’s less acidic and has a lower sugar content than the seeds and the gel surrounding them.
It’s the green parts you want to avoid. The leaves and stems contain tomatine, a toxic substance for turtles. So, ensure you’re only serving the fleshy, red parts of the tomato.
How Often Should Turtles Eat Tomatoes?
A good rule of thumb is to offer tomatoes to your turtle once every few weeks or less frequently, depending on your turtle’s overall diet and health condition. This infrequency ensures that your turtle isn’t exposed to the potential risks associated with regular tomato consumption, such as digestive upset due to the fruit’s acidity or potential calcium absorption issues due to oxalates.
Remember, the key to a healthy turtle is a varied and balanced diet. Turtles thrive on a mix of leafy greens, vegetables, and proteins like insects or commercial turtle pellets for some species. This variety meets their nutritional needs and keeps mealtime interesting for them.

Frequently Asked Questions
While turtles can technically eat tomato seeds, you can remove them before feeding tomatoes to your turtle. The seeds and the gel-like substance around them can contain higher acidity and sugars than the flesh of the tomato, which might not be ideal for your turtle’s digestive system.
Turtles should not eat tomato leaves, as they contain tomatine, a toxic alkaloid that can harm turtles and other pets. The stems and leaves of tomato plants are part of the nightshade family, which are known to contain substances that can cause adverse health effects if ingested.
Final Thoughts
While turtles can munch on tomatoes occasionally, it’s best to serve them sparingly due to concerns like acidity, sugar, and oxalates. Remember to keep tomato leaves and stems off the menu, as they’re not turtle-friendly. Mix them with other veggies and leafy greens to keep your turtle’s diet balanced and interesting.
