Squirrels are wild animals and can be prone to health issues if fed the wrong foods. A squirrel's diet should include a balance of protein, fat, vitamins, minerals, and calcium. While squirrels will eat almost anything, it is important to avoid foods that are high in sugar and starch, such as dried fruit, fruit juice, and grains. Additionally, certain nuts and seeds, such as cashews, sunflower seeds, and pine nuts, can be harmful and should be avoided. Peanuts, while a popular choice, have poor nutritional content and can lead to health issues such as Metabolic Bone Disease (MBD) if fed in large quantities. It is also important to be aware of the potential risks of feeding wild squirrels, including the transmission of parasites and the possibility of dependence on human food sources.

Peanuts and corn are unhealthy for squirrels and fail to provide nutritional benefits
Squirrels require a balanced diet containing protein, fat, vitamins, and minerals, including calcium. While squirrels are known to eat plants, animal-based material, nuts, seeds, tree flowers, and tree buds, it is important to be mindful of the nutritional content of the food you feed them.
Peanuts and corn are two foods that are commonly fed to squirrels but are not recommended due to their lack of nutritional benefits and potential health risks. Firstly, peanuts and corn contain dangerously high levels of phosphorus compared to calcium. This imbalance can lead to bone disease (MBD) in squirrels as their bodies will begin to pull calcium from their bones, resulting in potential health decline or even death.
Secondly, peanuts are known to carry a toxic fungus that can be harmful to squirrels. This fungus can grow on both raw and roasted peanuts and, if consumed, can be fatal to squirrels. Corn is also susceptible to the same type of toxic mold, which can kill squirrels quickly. Therefore, it is crucial to avoid feeding squirrels moldy peanuts or corn.
Additionally, peanuts and corn are high in starch and sugars, which can be detrimental to older, overweight, or less active squirrels. While these foods may be suitable for birds, they do not provide the same nutritional benefits to squirrels and should be avoided or fed in very small amounts as part of a varied diet.
Instead of peanuts and corn, it is recommended to feed squirrels a variety of other nuts, such as almonds, walnuts, hazelnuts, pecans, and acorns. These nuts provide a more balanced nutritional profile and help maintain the dental health of squirrels as they chew through the shells.

Nuts in their shells are a great source of nutrition and help keep their teeth healthy
Squirrels are some of the smallest tree-climbing animals and are known to eat nuts, seeds, plants, and even some animal-based material. While squirrels can eat a variety of nuts, not all nuts are created nutritionally equal.
Nuts in their shells are a great source of nutrition for squirrels and also help keep their teeth healthy. In-shell nuts are difficult to crack without a nutcracker, but squirrels can get through them using their teeth. This provides them with something constructive to gnaw on, a habit that is vital to keeping their teeth healthy.
Some of the most accessible nuts squirrels tend to come across are acorns, walnuts, and peanuts. However, other nuts like almonds, hazelnuts, macadamia nuts, English walnuts, pecans, pistachios, and beechnuts are also great options. These nuts provide wholesome fats, proteins, vitamins, and minerals that are essential to keeping squirrels healthy. For example, almonds are a great source of protein, fiber, fats, vitamin E, manganese, and magnesium.
It is important to note that while squirrels can eat peanuts, they should not be a staple in their diet. A varied diet is key to good health for squirrels, and too many peanuts can be detrimental. Instead, it is recommended to provide squirrels with a variety of nuts still in their shells, which can be found in nearby forests or purchased from specialty retailers.
In addition to nuts, squirrels also require other sources of nutrition to maintain a balanced diet. This includes high-calcium vegetables, other healthy vegetables, and fruits. It is important to avoid feeding squirrels processed foods, fast food, and junk food, and foods high in sugars, starches, or fat, as these can lead to health issues such as metabolic bone disease and diabetes.

Squirrels are prone to metabolic bone disease if they eat too much junk food
Squirrels are highly susceptible to metabolic bone disease (MBD) if they consume excessive junk food. MBD is a preventable condition that arises from improper diets or sickness in captive squirrels. It is caused by a disproportionate ratio of phosphorus to calcium in their diet, leading to phosphorus blocking calcium absorption. Squirrels, like children, may prefer junk food, but they need encouragement to eat healthily.
A balanced diet for squirrels should include protein, fat, vitamins, and minerals, especially calcium. While plant-based foods form a significant part of their diet, squirrels also eat some animal-based foods. Natural sources, such as nuts, seeds, and tree flowers, are suitable for squirrels. Nuts still in their shells, like walnuts, hickory nuts, and beechnuts, are excellent for squirrels' dental health.
However, some foods should be avoided or limited. Peanuts, for example, offer little nutritional benefit to squirrels and can be harmful if they become a staple in their diet. Similarly, corn, while fine in small amounts, does not provide substantial nutritional value. Other foods to avoid include Brazil nuts, chestnuts, salted nuts, and dried corn.
To prevent MBD, ensure your squirrel's diet has a proper balance of calcium and phosphorus. The recommended ratio is 2:1, with slightly more calcium being beneficial. High-calcium foods include arugula, beet greens, Chinese cabbage, and dandelion greens. If your squirrel is already showing signs of MBD, such as aggressiveness, excessive sleeping, or swollen joints, consult a veterinarian for advice on treatment, which may include calcium supplementation or adjustments to their diet.

Human food is not good for squirrels and can lead to malnutrition or even death
Squirrels have specific dietary requirements, and human food is not always suitable for them. While squirrels are omnivores, their diet is predominantly plant-based. They typically eat a variety of seeds, nuts, fruits, vegetables, buds, catkins, flowers, and stems. They also strip bark from trees and eat fungi, berries, and even tree sap.
In the wild, squirrels can find an adequate food supply and do not need to rely on human food sources. However, when humans start feeding squirrels, the animals can become dependent on these handouts and lose their ability to forage for themselves.
The United States Department of Agriculture (USDA) warns that "wild animals have specialized diets, and they can become malnourished or even die if fed the wrong foods." Squirrels are prone to Metabolic Bone Disease (MBD), and consuming too much junk food or the wrong types of food can put them at risk of health complications.
Some human foods that should be avoided when feeding squirrels include:
- Dried fruit, such as dates, figs, raisins, and plums
- Corn and peanuts—while not harmful, they do not provide much nutritional benefit
- Salted nuts—these contain too much sodium for squirrels
- Cashews, sunflower seeds, dried corn, and pine nuts—these can cause severe calcium loss
It is important to provide a balanced diet for squirrels, including protein, fat, and vitamins and minerals, such as calcium. A varied diet is key to maintaining the health of these bushy-tailed creatures.

Squirrels can survive without human food and may become dependent on handouts
Squirrels are omnivores, and their diet primarily consists of plant-based foods like nuts, seeds, flowers, buds, and fungi. They also eat some animal-based foods, including insects, amphibians, bird eggs, and even bones. In the wild, squirrels can survive without human food, as they are adept at foraging for themselves.
The debate over whether humans should feed squirrels is a contentious issue. On the one hand, many people enjoy interacting with these bushy-tailed creatures and providing them with food. Additionally, supplementary feeding can provide nutritional benefits if done correctly. For example, nuts in their shells provide a healthy treat and help keep their teeth healthy.
However, there are several reasons why wildlife experts advise against feeding squirrels human food. Firstly, squirrels have specialized dietary needs, and human food may not provide the necessary nutrients. For instance, corn and peanuts are commonly fed to squirrels but offer little nutritional benefit. A squirrel's diet should be varied, and a reliance on human food can lead to malnutrition.
Secondly, when squirrels become accustomed to receiving food from humans, they can become dependent on these handouts. If the source of human food disappears, the squirrels may struggle to become self-sufficient again, impacting their ability to survive. Additionally, human food can be harmful to squirrels if it is high in sugars, starches, or fat, or if it contains substances like sodium that are unhealthy for them in large quantities.
Finally, feeding squirrels can have unintended consequences for human property. Squirrels are known to cause damage to wires and insulation in attics and siding, and some people believe that this behavior is encouraged by the presence of human-provided food.
Therefore, while squirrels are beloved by many and can benefit from supplementary feeding in some cases, it is essential to prioritize their health and well-being. Providing a varied and natural diet, minimizing dependence on human food, and being mindful of potential property damage can help ensure that human-squirrel interactions are positive for both parties.
