Can Parrots Eat Spinach? [Leafy Green High in Oxalates]

(Last Updated On: October 12, 2022)

Spinach (also known as Spinacia oleracea) is considered a “superfood” due to its high nutrient and vitamin content. While this nutritious leafy green vegetable is highly beneficial to human health, many people wonder if it holds the same health benefits for parrots.

There are nutritious foods that are safe for human consumption that can’t be fed to parrots, which is why owners question whether spinach leaves are safe for their parrots to eat.

Parrots can eat spinach, as it’s a good source of calcium, protein, Vitamin A, iron, magnesium, and potassium. Also, its antioxidant properties reduce oxidative stress from free radicals, preventing disease.

However, spinach is high in oxalic acid, which inhibits mineral (calcium) absorption. While a small amount of spinach (especially if it’s boiled) will cause minimal harm, too many oxalic acid-rich vegetables increase the risk of egg binding and kidney stones.

Can You Feed Parrots Spinach?

Parrots need various nutrients, vitamins, and minerals to stay healthy. So, their diets should include a combination of parrot pellets, fruits, grains, seeds, and vegetables.

Parrot pellets are manufactured to include many nutrients and vitamins that parrots need in their diets. However, parrot pellets shouldn’t be the only kind of food you offer parrots.

Eating the same thing daily will get boring, so giving your parrot other foods besides the parrot pellets is recommended. Also, dietary diversity results in healthier, more energetic, and stronger parrots.

Vegetables should make up most of the other types of food your parrot eats. However, some vegetables are more nutritious than others, such as leafy green vegetables like spinach.

Is Spinach Good for Parrots?

Spinach is healthy for parrots, whether it’s raw or cooked.

According to the International Journal of Life Sciences and Review, spinach contains many nutritional properties that are beneficial to health, including the following:

  • Vitamin B6
  • Riboflavin
  • Folate
  • Niacin
  • Soluble dietary fiber
  • Omega 3 fatty acids
  • Iron
  • Vitamin K
  • Flavonoids
  • Carotenoids (Vitamin A)
  • Vitamin C
  • Folate
  • Vitamin E
  • Potassium
  • Magnesium
  • Manganese
  • Copper
  • Vitamin B2
  • Calcium
  • Vitamin C
  • Zinc
  • Phosphorus
  • Vitamin B1
  • Choline
  • Protein
  • Chlorophyll
  • Lutein

Antioxidants include flavonoids, lutein, vitamins C and E, carotenoids, and phenolic compounds. The antioxidants in spinach reduce the damage caused by free radicals and oxidative stress.

According to the National Library of Medicine: National Center for Biotechnology Information, oxidative stress can contribute to the development of various degenerative diseases.

Eating foods high in antioxidants, such as spinach, can help reduce oxidative stress and lower the risk of developing many degenerative diseases.

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology studied the impact of dietary antioxidants and flight training on oxidative damage in adult parrots. The parrots used in the study were fed spinach and given flight training sessions as a form of exercise.

It was determined that with the combination of flight training and antioxidants, the parrots’ oxidative damage was reduced over the 9 weeks.

Innovative Food Science & Emerging Technologies found that fresh raw spinach and frozen spinach have the highest antioxidant properties compared with canned and jarred spinach.

The preparation method used before eating spinach can affect the overall number of antioxidants in spinach, which is why canned and jarred spinach contain fewer antioxidant properties than fresh, raw, and frozen spinach.  

Based on this information, feeding spinach to your parrot can benefit its health. However, it’s best to use raw or frozen spinach so your parrot will get the most antioxidant benefits from spinach.

Vitamin A

Vitamin A is a fat-soluble vitamin that doubles as an antioxidant. Ensuring your parrot gets enough Vitamin A will reduce its risk of developing fungal, bacterial, and viral infections.

Vitamin A boosts your parrot’s immune system, which fights off infections and diseases. It’ll also keep your parrot’s eyes, skin, and feathers healthy.

Vitamin K

Vitamin K helps keep your parrot’s bones strong and its blood flowing properly.

If your parrot has a Vitamin K deficiency, it can lead to weakened bones, bone fractures, injuries, and blood clotting issues.


Spinach is a good source of iron for parrots. Iron is involved in creating hemoglobin, which carries oxygen through the blood to different body parts.

Eating iron-rich foods prevents parrots from developing anemia, which can make parrots feel tired and weak. However, too much iron is bad for parrots as it can cause iron storage disease.

Iron storage disease can cause iron buildup in the lungs, heart, and other organs. When a parrot has too much iron in its system, these organs store that excess iron which can cause organ damage.

There usually aren’t signs that a parrot has iron storage disease until the disease has progressed. The symptoms can include the following:

  • Difficulty breathing
  • Swollen abdomen
  • Paralysis

Give your parrot a diet consisting of various foods with and without iron.

is spinach toxic to parrots?


Protein (amino acids) is important, as it ensures their bodies stay healthy and function properly. Spinach is a good protein source that assists with muscular development and regeneration.

If you want to give your parrot more protein, parrots can eat small amounts of certain meat and fish.


Spinach is high in calcium, which helps keep bones strong and healthy. Without adequate amounts of calcium, parrots can develop a calcium deficiency, which can lead to the following:

  • Bone weakness
  • Bone fractures
  • Muscle pain
  • Heart issues
  • Self-destructive behaviors
  • Stress
  • Seizures

Ensuring your parrot receives plenty of calcium through spinach and other calcium-rich foods is important for maintaining its health..


Spinach has more magnesium in it than many other vegetables and fruits.

Magnesium keeps your parrot’s muscles and nerves healthy. It helps the bones grow healthy and strong, regulates body temperature, and prevents seizures.

If parrots don’t get enough magnesium in their diets, it can lead to difficulties synthesizing calcium.

Does Spinach Contain Oxalates?

Many people worry about feeding too much spinach to parrots. Spinach contains oxalic acid, which binds to calcium, prevents absorption, and can cause kidney problems and egg binding (dystocia).

According to the Journal of Agricultural and Food Chemistry, boiling spinach reduces its oxalate content by 30-87%. When consumed in moderation, spinach leaves won’t cause any health issues.

How Much Spinach Can Parrots Eat?

As with all foods, you’ll want to give your parrot spinach in moderation. Adding a couple of spinach leaves to its food a couple of times a week is beneficial.

If you’re feeding your parrot a well-balanced diet with various foods, you don’t have to worry about overfeeding spinach to your parrot.
