Can Turtles Eat Grapes

Most people consider turtles to be too small and inconsequential to be a pet. Only those who own turtles know how far from the truth that is. Turtles are believed to be the symbol of luck in many ancient cultures. Even though they mostly keep to themselves and are content with whatever attention you give them, if you care for them, they will be affectionate towards you, too.

When it comes to the diet of turtles, most of the pet owners have no clue what to feed them except store-bought feed. But surely turtles can enjoy certain fruits and vegetables as an occasional treat? What about grapes? Turtle owners often wonder whether or not grapes are healthy for turtles.

Can turtles eat grapes? The short answer to this is: yes, they can. Some of the turtle breeds even love these fruits. However, like many other fruits, grapes have an unbalanced calcium-phosphorus ratio, which can be unhealthy for turtles in the long run. Moreover, too much sugar is not ideal for turtles either. Therefore, it is best to feed your turtle grapes in moderation.

Now let’s discuss which of these nutrients are healthy for turtles.


As far as vitamins are concerned, turtles only need two of them: vitamins A and D. While grapes do not contain vitamin D, it is rich in vitamin A. Vitamin A is essential for maintaining their eyesight, epithelial tissues, reproductive health, and body growth. It also strengthens their immune system.

A lack of vitamin A can lead to several health problems in turtles.

  • Ear and aural abscesses
  • Vision problems
  • Hypervitaminosis A
  • Squamous metaplasia


To maintain their bone and shell health, turtles need calcium and phosphorous. Fortunately, grapes contain both of these minerals.

Due to the presence of these vitamins and minerals in grapes, these fruits can be considered healthy for your shelled pet.


Can grapes be harmful to turtles?

Can grapes be harmful to turtles

As long as you feed grapes to your turtle in moderation, it will not harm their health in any way. However, the problem arises when you get careless with the quantity you are feeding them. Let’s figure out how and why.

Incorrect calcium-phosphorus ratio

Although grapes contain both these minerals, the ratio between the two is not well-suited for turtles. Turtles need the calcium-phosphorus ratio to be 2:1, where the quantity of calcium is twice as much as phosphorus.

In grapes, the ratio is quite the opposite of it. For instance, in 100 grams of grapes, there is 10 mg of calcium and 20 mg phosphorus, making the ratio 1:2. The improper amount of calcium can cause bone diseases in turtles.


The bacteria in a turtle’s stomach can only digest a small amount of sugar. Excessive sugar consumption can destroy these bacteria leading to digestive problems and potentially fatal poisoning in them.

Grapes are rich in sugar; 100 grams of grapes contain about 15 grams of sugar, which is too much for your little pet. Therefore, it is best if you feed your turtle grapes once in a week as a snack.
