Benefits of blueberries

The beneficial properties of blueberries are not just a matter of popular belief. Scientific research has proven the extremely positive impact that continued consumption of blueberries can offer our bodies, as well as those of our dogs and cats. Here are some of the main benefits of blueberries in cats and dogs:

1. Non-stick properties

Formerly, blueberry juice was used to treat and cure urinary tract infections. It was believed that this fruit would be able to acidify the urine, thus eliminating the pathogens. Although there is still no scientific agreement on the ability to acidify urine, blueberries are known to have anti-adherent properties, which prevent the adhesion of bacteria and other microorganisms that surface in the urinary system. This effect allows the prevention of urinary tract infections, cystitis and the formation of stones in cats and dogs.

An experiment carried out by researchers from the Veterinary Hospital of the University of California, demonstrated the non-stick properties of blueberry extract. The professionals administered daily extract in dogs with a clinical history of recurrent urinary tract infections.

After 2 months of analysis and collection of samples, a significant reduction in the adhesion of E. coli bacteria was observed in the cells after comparing cultures of urine samples obtained before the administration of the extract, 30 and 60 days later. The results indicate that the consumption of blueberry extract can be very beneficial to prevent urinary tract infections in dogs. [1]

2. Antioxidant properties

Arteriosclerosis, which is one of the main causes of cardiovascular diseases and strokes, begins with the oxidation of LDL cholesterol molecules (the so-called "bad cholesterol"), which leads to an accumulation of insoluble lipid plaques inside the body arteries, interference of blood circulation and the damage ofoxygenation of the body.

As indicated in the article "Cranberry Flavonoids, Atherosclerosis and Cardiovascular Health", several experiments in vivo and in vitro proved that the flavonoids and phenolic acids presented in blueberries and in other wild berries have antioxidant action, giving them the ability to inhibit oxidation of LDL cholesterol and aid in preventing the adhesion of "bad cholesterol" plaques in the arteries.

As a result, regular consumption of blueberries, either in food (organic berryjuice) or through supplements, can prevent arteriosclerosis and reduce the risk of heart disease, myocardial infarction, cardiovascular accidents (CVA) and stroke. [2]

3. Digestive properties

The fibers contributed by the blueberries stimulate intestinal transit and favor digestion. Therefore, berry juice is one of the best home remedies for constipation. In addition, some more recent studies show the presence of bilberry’s, which are rich in natural prebiotics.

Prebiotics are non-digestible plant substances that serve as food for the beneficial bacteria of the intestinal flora of dogs, cats and humans. Therefore, blueberries would not only help improve digestion, but also strengthen the immune system.

4. Metabolic properties

Berries are rich in a set of phytochemicals with antioxidant action that help prevent cell damage. Despite being known for their "anti-aging" function, polyphenols also help in the fixation of calcium, preventing the loss of bone mass, which is common in older dogs and cats.

In addition, according to a recent study carried out by the University of Maine, flavonoids presented in blueberries and other berries help prevent the risk factors associated with metabolic syndrome, such as obesity, hyperglycemia, hypertension, inflammation , insulin resistance, etc. This effect is be an important ally in the control of blood glucose and the prevention of diabetes in cats, in addition to reducing the risk of cardiovascular diseases. [3]

5. Anticancer properties

Recent research carried out by the University of California show the in vitro efficacy of extracts of blueberries, black and red berries, strawberries and cauliflowers in inhibiting the growth of cancer cells in the human body. In addition, the researchers assume that the polyphenols in these berries could also protect the DNA from oxidative stress, preventing the abnormal growth of the cells that give rise to the tumors.

Indications and uses of blueberries in dogs and cats

    • Strengthen the immune system: cranberries contain essential nutrients for strengthening the immune system, such as vitamins A and C, fiber, calcium and proteins. And since it is a fruit low in calories and fat, it can be consumed moderately even by overweight animals.
    • Prevent degenerative diseases: the antioxidant properties of flavonoids and phenolic acids presented in cranberries are vital to combat free radicals and prevent degenerative and cardiovascular diseases.
    • Improve intestinal transit: the supply of fibers provided by cranberries helps improve intestinal transit and acts as a natural remedy for constipation in dogs and cats. For the same reason, excessive consumption can cause diarrhea in our pets.
    • Combat urinary tract infections: blueberries were historically used to combat urinary tract infections. Although it is not proven that blueberries acidify urine, its non-stick property helps prevent bacteria from attaching to the urinary tract, preventing infections.
    • Stimulate circulation: blueberries contain bioflavonoids known as "vitamin P" that have an anticoagulant effect in the body. When used in safe doses, they stimulate circulation, helping to prevent the formation of clots and associated conditions, such as thrombosis and vascular problems in the eyes.
    • Prevent diabetes and balance the metabolism: as we have mentioned, the phytochemicals present in bilberry can prevent risk factors of the metabolic syndrome, including hyperglycemia, obesity and diabetes.

              Side effects of blueberries in dogs and cats

              Because of its fiber content, blueberries stimulate intestinal transit and can cause diarrhea or an upset stomach when ingested in excess. In addition, since they contain oxalic acid, their excessive consumption can also favor the development of calcium oxalate stones in kidneys or bladder. On the other hand, the anticoagulant properties of the fruit, if not used properly, can cause bleeding.

              Although it is not proven, it is estimated that, when helping to fix calcium problems, excessive consumption of blueberries can interfere with the assimilation of iron. In addition, infusions of blueberry leaves can also cause hydroquinone poisoning and are therefore not recommended for dogs and cats.

              Blueberry dosage for dogs and cats

              Regular consumption of blueberries is normally beneficial for our pets, provided we respect safe doses. However, there is no single defined dose for dogs and cats. The dose should be adequate to the weight and health status of each animal.

              Therefore, it is essential that you consult your veterinarian before offering your animal juice, extract or capsules that contain blueberry. A trained professional can guide you on the amount needed and the best form of administration to obtain a positive impact on the health of your animal.
