In a nutshell, acorns are rich in antioxidants, improve gut health, and are abundant in the wild.

Antioxidants are important for you because they contain vitamins A and E and prevent the chances of many chronic illnesses. Because this fruit is rich in fiber, it helps regulate your gut bacteria and saves you a lot of trouble. 

Lucky for you, you can find this natural medicine in a hundred or even a thousand pieces because over 400 oak trees produce acorns.

Acorns help the digestive system – they are the ideal fruit for people who have problems with irregular bowel movements, cramping, and bloating.

Antioxidants contained in acorns like gallic acids, ellagic, and tannic acids reduce asthma symptoms.

The fiber content and carbohydrates reduce sugar and glucose levels and therefore prevent the danger of diabetes.

Minerals like potassium and calcium contribute to bone health.

Vitamin B12 helps regulate metabolic activities which are important for overall body health.

It is said that some antioxidants contained in acorns help prevent memory loss and lower the symptoms of Alzheimer’s disease

Acorns have a specific look so you should know how to eat them. Before you start, be sure to remove all tannins. When this has been done, harvesters recommend the following:

  1. Choose fully grown and brown acorns.
  2. Rinse to remove dirt and insects.
  3. Remove hard shells using a nutcracker.
  4. Boil in a pot for 5 minutes until the water boils clear.

The Ecological Role Of Acorns

Acorns have an important role in the ecological system because they are found in large quantities in the forest.

Some of the most popular species that use this fruit as food are woodpeckers, squirrels, and ducks. Acorns also have an important influence on small rodents. Larvae and moths usually spend their lives in acorns.

Even large mammals such as pigs and bears tend to consume large amounts of acorns and they represent 25% of their entire diet in autumn.

Since acorns contain tannins (plant polyphenols), animals must adapt in different ways to use this nutritional value. Excessive consumption of acorns may be toxic to animals that find it difficult to digest tannins like horses or cattle.

According to the vet, because acorns contain large amounts of tannins, they can cause diarrhea and stomach problems in most animals. You should keep this fruit away from your dog and consult a vet if you have any questions or concerns.

  • The term “tannins” has been mentioned several times already. This is because this antioxidant poses a major threat to your little furry friend. Certain animals like dogs have a hard time digesting this ingredient and this might result in terrible stomach problems.
  • Kidney failure is a case scenario that rarely occurs but should not be excluded. This is also the doing of “tannins” and it starts with terrible pain in the abdominal part. 
  • Lethargy is also a common outcome of eating an excessive amount of acorns. If your dog is lethargic, he will most probably show symptoms like weakness and you should immediately visit the vet and get proper medication.
