A few unsalted, unseasoned cashews can be a safe and healthy addition to a parrot’s diet. Cashews are a good source of protein, copper, magnesium, zinc, manganese, phosphorus, and vitamins B6 and K.
Cashews are linked to a reduced risk of atherosclerosis and strokes. They protect the body against oxidative stress and joint conditions like osteoarthritis while providing sustainable energy.
Some parrots favor nuts over other foods due to their rich and fatty texture, rejecting less flavorful foods. An entirely nut-based diet will lead to malnutrition, as parrots must eat different foods to thrive.
Benefits of Cashews for Parrots
Cashew nuts contain the following vitamins and minerals:
Copper
Cashew nuts are an excellent source of copper, which parrots need for heme (iron compound) synthesis. It also leads to healthy blood vessels, bones, and connective tissue.
Zinc
Even though parrots only need some zinc, it helps form insulin and allows vitamin A (retinol) binding.
Selenium
According to Environmental Contaminants in Biota, selenium is a chemical compound that boosts the immune system, growth, reproduction, and thyroid hormone production.
Iron
Parrots need iron to create hemoglobin, which carries oxygenated blood around the body. Cashews minimize the risk of anemia, preventing parrots from feeling weak and lethargic.
Magnesium
Magnesium is an essential mineral for nerves and muscles. A 28.35 g serving of cashew nuts contains 82.8 mg of magnesium, more than spinach, cherries, and cauliflower.
Magnesium assists in the following ways:
- Bone development and growth.
- Temperature regulation.
- Seizure prevention.
Magnesium deficiencies can lead to hypocalcemia (calcium deficiencies). To keep parrots healthy, especially egg-laying females, you must feed them foods rich in this mineral.
Manganese
Manganese assists in the formation of healthy bones and eggshells. Female parrots need more manganese than males, allowing them to reproduce more successfully.
Without sufficient manganese, parrots are at risk of:
- Perosis, which leads to physical deformities.
- Poor muscle coordination.
- Tarsometatarsal joint dislocation.
Manganese is also found in bamboo, tea, seeds, whole grains, and leafy vegetables.
Phosphorus
Phosphorus is found in a parrot’s bones and bodily tissue. It maintains healthy eggshells and improves bone formation. Phosphorus also assists in:
- Waste filtration.
- Repairing tissue and cells.
- Metabolizing fats and carbohydrates.
- Allowing the body to use lipids and proteins.
Vitamin K
Vitamin K is among the most vital vitamins for parrots because it keeps the bones healthy and strong, reducing the risk of:
- Injuries.
- Weak, brittle bones.
- Breaks and fractures.
- Heavy bleeding.
Parrots spend their days perching, so weak bones make this difficult and uncomfortable.
Vitamin B6
Cashew nuts contain vitamin B6 (pyridoxine), which turns carbs and proteins into energy. As Vitamin B6 is water-soluble, parrots must eat foods that include it daily.
Protein
A 28.35 g serving of cashew nuts contains 5.16 grams of protein.
Parrots are omnivores, so they need protein to stay healthy. Amino acids are the body’s building blocks, essential for physical development and healthy feathers.
Protein is a macronutrient that should account for 10-20% of a parrot’s diet.
Risks of Giving Parrots Cashews
Cashews aren’t toxic, but they should be consumed in moderation. Problems include:
Phytic Acid
Phytic acid (inositol hexaphosphate or IP6) is a food inhibitor in plant seeds, including cashew nuts. It binds to certain minerals, inhibiting absorption. This includes:
- Calcium.
- Zinc.
- Iron.
- Magnesium.
- Manganese.
Once this binding process occurs, the body can’t access the nutrients, contributing to mineral deficiencies. Measures must be taken to remove “anti-nutrients” and benefit from their complete nutritional profile.
Soak raw cashews in water for 2-3 hours to break down and release anti-nutrients like phytic acid and lectin into the water. This will allow for easier digestion and absorption of nutrients into the body.
Fat
Cashew nuts are high in fat, containing 12.4 g per 28.35 g.
Conservation Physiology explains how diet plays a significant part in obesity. Weight gain can negatively affect a parrot’s life, causing joint pain, fatty liver disease, and organ failure.
Excess weight also puts much pressure on the legs and feet, making injuries much more likely.
While cashew nuts are high in fat, they’re primarily monounsaturated (healthy) fats.
Aspergillosis
Nuts can be infected with Aspergillus, a toxin derived from mold. This can cause parrots to develop aspergillosis, an infection characterized by:
- Chest pain.
- Difficulty breathing.
- Fever.
- Shortness of breath.
Raw cashews can harbor Aspergillus. If a parrot eats moldy nuts, its health will decline.
To check if cashews are moldy, do the following:
- Only buy human-grade cashews from reputable sources, like grocery stores.
- Cut each cashew in half. If you see white mold or discoloration, throw it away.
- Take note if there’s a sour odor or wrinkled appearance, as this suggests it has gone off.
- Wash the nuts under hot water to remove hidden traces of mold.
Raw Cashews
Raw cashews are okay, but they carry the risk of mold. Always carefully inspect each cashew.
Roasted Cashews
Cashews can be baked in the oven but shouldn’t be cooked in soybean, corn, canola, sunflower, and safflower oil. Their refining process makes them unhealthy for avian consumption.
Salted Cashews
Parrots shouldn’t eat salted cashew nuts because too much sodium leads to excessive thirst (polydipsia) and high blood pressure (hypertension).
Chocolate Cashews
Chocolate is among the most toxic human foods for parrots because it contains theobromine. This stimulates the nervous system and heart, with life-threatening consequences.
Chocolate is also harmful because it contains butter and milk. After all, birds lack the lactase needed to digest lactose. The high fat and sugar content can also lead to obesity.
If you inspect each nut for signs of mold, plain cashew nuts (unsalted and unseasoned) are a healthy dietary addition for parrots. Here’s some further information on feeding parrots nuts.
