Fruit is really good for dogs \u2026 even though some raw feeders would never include fruits in their dogs\u2019 diets. But whether you feed raw, prey or processed kibble, adding fruit to your dog\u2019s diet can give him an important health boost. There\u2019s one compelling reason that makes fruits good for dogs \u2026 and that\u2019s polyphenols.<\/strong> <\/p>\n

What Are Polyphenols?<\/h2>\n

Polyphenols are natural compounds in fruit and plants<\/strong>. They have antioxidant, anti-inflammatory, immune-supporting properties \u2026 and more. <\/p>\n

Many fruits have high polyphenol content. In berries and apples there\u2019s up to 300 mg of polyphenols per 100 grams of fresh fruit (7). Some spices, herbs, nuts and vegetables contain good amounts of polyphenols too.<\/p>\n

Why Are Polyphenols Important?<\/h2>\n

We\u2019ve long known that diets rich in fruits and vegetables protect people from cancers, heart disease, diabetes and more<\/strong> (1). Now research shows these health benefits come from polyphenols (2). <\/p>\n

Polyphenols prevent degenerative diseases like cancer, cardiovascular disease and neurodegenerative diseases (3). Your dog can\u2019t digest polyphenols but the bacteria in his colon can. Beneficial bacteria produce short-chain fatty acids (SCFA) that have many other vital roles (4) in the body. They\u2019re a source of energy, protect the gut lining and support the immune system<\/strong>. <\/p>\n

6 Important Benefits Of Fruit For Dogs<\/h2>\n

Fruits and vegetables provide your dog with hundreds of nutrients including polyphenols. Here are some reasons to give your dog fruits.<\/p>\n

1. Manage Chronic Inflammation<\/h3>\n

Inflammation is a natural part of the body\u2019s immune system. It\u2019s helpful in the short term when your dog is sick or injured. Immune cells come to the affected area to fight disease and repair damaged tissues.<\/p>\n

Ongoing acute inflammation can become chronic inflammation (5). This is very common in dogs and is linked to serious health problems like \u2026<\/p>\n

    \n
  • Cancer<\/li>\n
  • Allergies<\/li>\n
  • Heart disease<\/li>\n
  • Joint disease<\/li>\n
  • Diabetes<\/li>\n
  • Autoimmune diseases<\/li>\n<\/ul>\n

    In a 2014 study (6), researchers fed three groups of rats different diets for 2 months. The first group ate rat chow and the second ate a high fat, high sugar diet. The third ate the same high fat, high sugar diet but with cranberry juice as well. The researchers analyzed the rats\u2019 livers and found the ones who had cranberry juice had fewer inflammatory markers. The polyphenols in the cranberries had two effects: they suppressed inflammatory enzymes and slowed down pro-inflammatory immune cells called cytokines. <\/strong><\/p>\n

    In a 2016 review of animal studies, quercetin showed anti-inflammatory effects in obese rats (7) .  A high-fat diet was supplemented with quercetin for 10 weeks and improved blood pressure, insulin sensitivity, and other factors in the rats.<\/p>\n

    2. Provide Antioxidants<\/h3>\n

    Free radicals cause chronic inflammation. They\u2019re damaged molecules that repair themselves by stealing molecules from the cells. This process can even harm DNA. If not controlled, free radicals build up and cause chronic inflammation and ultimately chronic disease and premature aging. <\/p>\n

    Antioxidants neutralize free radicals (8) that can damage cells and lead to diseases like cancer, diabetes and heart disease. Polyphenols in fruit, like <\/strong>curcumin<\/strong> and resveratrol, seek out free radicals. <\/strong>Feeding polyphenols found in fruit can help combat oxidative stress caused by environmental toxins, stress and poor diet.<\/p>\n

    3. Reduce Cancer Risk<\/h3>\n

    Research shows that polyphenols reduce the risk of cancer <\/strong>(9). And researchers at Rutgers, State University of New Jersey, found they can inhibit cells that cause DNA methylation (9.1). That\u2019s a major link to cancer. They also reactivate silenced genes in cancer cells and cause their death (apoptosis).<\/p>\n

    A 2010 study at the University of South Carolina looked at resveratrol, a polyphenol found in fruits like apples (10). Resveratrol reduced bacteria linked to colon cancer. This polyphenol, along with others, controls cancer cell growth and division. This means when your dog eats fruit, cancer cells are less likely to spread in your dog\u2019s body.<\/p>\n

    4.  Lower Blood Sugar Levels<\/h3>\n

    There\u2019s evidence polyphenols help lower blood sugar levels and manage the risk of diabete<\/strong>s in your dog (11, 12). Studies show polyphenols in the diet lower fasting blood sugar levels, raise glucose tolerance, and increase insulin sensitivity. These are important factors in lowering the risk of diabetes. In a 2017 study published in the British Journal of Nutrition, people eating the highest amounts of polyphenol-rich foods had a much lower risk of developing type 2 diabetes over 2\u20134 years, compared with those eating the lowest amounts (13). So research suggests that the anthocyanin component of polyphenols has the highest antidiabetic effect  (14, 15). That\u2019s a strong reason to feed your dog some<\/strong> red, purple, and blue foods like berries<\/strong>.<\/p>\n

    5. Support Gut Health  <\/h3>\n

    Feeding your dog feeds the few trillion bacteria that live in his gut. Protein and healthy fats feed the friendly bacteria in his gut. Your dog\u2019s friendly bacteria help produce vitamins, strengthen the gut lining and modulate the immune system. <\/p>\n

    Toxins and starch in your dog\u2019s diet can feed the bacteria that produce inflammatory by-products that lead to disease. A good population of friendly bacteria can crowd the harmful bacteria. Polyphenols feed the friendly bacteria so they can thrive.<\/strong><\/p>\n

    The polyphenol, catechin, can stop the growth of bacteria. This includes E coli, Bordetella bronchiseptica (kennel cough bacteria) and salmonella. Quercetin can also stop E. coli from growing. <\/p>\n

    6. Detox The Liver<\/h3>\n

    Natural polyphenols have attracted attention in studies for the prevention and treatment of liver diseases caused by the toxic world that surrounds your dog (16). His food contains pesticides and toxins on top of his exposure to  chemicals, drugs, vaccines and cleaners. Toxins build up in your dog and cause chronic health problems. Your dog\u2019s liver can process and remove most toxins from food and the environment. But some fat-soluble toxins are hard for the liver to metabolize. Instead, these toxins cling to liver cells and build up over time. And this can cause free radicals to accumulate in the liver as well. <\/p>\n

    Polyphenols support the liver\u2019s two-phase detoxification process<\/strong> that removes fat-soluble toxins. In Phase 1 detox, enzymes neutralize toxins by converting them into less harmful molecules. But these molecules can still damage the body. So Phase 2 enzymes make these byproducts water-soluble so they can leave the body.   <\/p>\n

    Which Fruits Are Good For Dogs?<\/h2>\n

    Fruits, veggies, seeds and herbs can, and should, be an important part of your dog\u2019s diet. Even wolves scour their environment for fruits and veggies. In the summer months, up to 25% of their stomach contents are fruit and other plant matter.<\/p>\n

    But variety is key!<\/strong> Because each fruit gives your dog different health benefits and polyphenols. To help you select a good variety of fruits (and vegetables) for your dog, you want to consider 4 major classes of polyphenols (8):<\/p>\n

    Flavonoids<\/h3>\n

    They\u2019re anti-inflammatory, have cancer-fighting properties and improve cognitive function. There are more than 5,000 different compounds in flavonoids so it\u2019s got many subclasses:<\/p>\n

      \n
    • Flavonols contain quercetin, which can reduce inflammation and fight cancer. Foods include <\/strong>apples<\/strong>, <\/strong>berries<\/strong>, <\/strong>kale and broccoli.<\/li>\n
    • Anthocyanin (15) has antioxidant effects<\/strong>. It\u2019s found in red, blue and purple berries <\/strong>like blueberries, raspberries and cranberries.<\/li>\n
    • Flavanones contain hesperidin, a special antioxidant that can protect the brain<\/strong>. It\u2019s found in citrus fruits like oranges, lemons and clementines.<\/strong><\/li>\n
    • Flavanols contain catechin, which inhibits the growth of pathogenic bacteria<\/strong>. It\u2019s found in berries and apples<\/strong>.<\/li>\n
    • Flavones: found in parsley, celery, hot peppers.<\/li>\n
    • Isoflavones: Genistein is an isoflavone, which can prevent tumor formation<\/strong>, and is found in soy-based foods. Other sources are legumes and alfalfa. <\/li>\n<\/ul>\n

      Phenolic Acids<\/h3>\n

      These are in the seeds and skin of fruits and in vegetables. They <\/strong>scavenge free radicals. <\/strong>Curcumin, the active constituent in turmeric, is one of the most notable phenolic acids. It disrupts cytokine activity to lower chronic inflammation. <\/p>\n

      Lignans<\/h3>\n

      They\u2019re found in apricots, <\/strong>broccoli, leafy greens, and flax seeds. They\u2019re useful in fighting hormone-associated cancers and can also be antioxidants. A 2016 Chinese study found lignans fed bacteria in the gut known to be beneficial in killing tumor cells (9).<\/p>\n

      Stilbenes<\/h3>\n

      They contain resveratrol, which is anti-inflammatory and can fight cancer. <\/strong>They\u2019re found in blueberries, raspberries, and mulberries.<\/strong><\/p>\n

      So you really need to add fruits (as well as vegetables, herbs and seeds) to your dog\u2019s diet. They offer your dog valuable disease-fighting benefits.<\/p>\n

      Why Kibble Isn\u2019t A Good Source Of Polyphenols<\/h2>\n

      Kibble doesn\u2019t even come close to providing a fraction of these benefits. Heating and processing food reduces its nutrition, changing its molecules. Cooking food destroys 5% to 50% of vitamins.  <\/p>\n

      Studies (17) have found that cooking fruits and vegetables destroy many of the polyphenols. Boiling foods can remove half their polyphenols. Frying can cause a 60% loss and the loss was higher during steaming (18). And the free radical scavenging activity decreases by 60% with boiling and 30% with steaming. <\/p>\n

      So fresh is always best when it comes to fruits for dogs.<\/strong> You can add fruit directly to kibble to boost your dog\u2019s nutrition. But there are a few things to know \u2026<\/p>\n

      Cautions With Fruit<\/strong>
      Never feed unripened fruit, and introduce new fruits in small amounts. Too much, too soon can cause an upset stomach and diarrhea. Always remove stones in fruit like plums as they can cause blockages. And finally, don\u2019t overfeed fruit to diabetic dogs or a dog with severe inflammation. <\/p>\n

      Don\u2019t forget that some fruits can be toxic to dogs! Always double-check to make sure he can eat the fruits and vegetables you\u2019re giving him. <\/p>\n

      Now you know how polyphenols can help your dog, add some fruits to his meals and watch him flourish! <\/p>\n
