Vegetables contribute critical nutrients, healthy phytonutrients, and soluble and insoluble fiber to a raw diet for dogs. Vegetables help to fill nutritional gaps in diets that don't involve the regular usage of entire prey.

Although vegetables are not required for critical nutrients in dogs' meals, adding plant ingredients to raw diets is beneficial. All vegetables must be prepared for efficient digestion and nutrient absorption because dogs lack the jaw structure to grind plant materials and the salivary enzymes to begin carbohydrate digestion in the mouth.

Each vegetable type has its own set of benefits. 

Protein, fat, and carbs are the three primary macronutrients found in food. Carbohydrate refers to various carbohydrate types, including starch, fiber, and sugar.

Starch: Starch is a complex carbohydrate made up of several glucose molecules linked together by glycosidic bonds. After enzymatic digestion, starch is converted into individual glucose molecules and used as an energy source. Before feeding, carbohydrates must be appropriately prepared to be enzymatically digested and utilized for energy. Otherwise, the starch resists enzymatic digestion and ferments in the colon.

Fiber: Fiber is a form of carbohydrate that enzymes in the stomach or small intestine can't break down. The fiber is delivered to the colon, where the intestinal flora ferments it. Fiber fermentation encourages the production of short-chain fatty acids (SCFAs), which benefit colon health. Fiber fermentation also promotes the production of vitamin K.

Sugar: Sugar is a carbohydrate that comes in various forms, including glucose. Sugar is found naturally in vegetables. However, the amount varies depending on the type of vegetable. Starchy veggies, on average, have greater sugar levels than low-glycemic vegetables.

Phytonutrients are chemical molecules that plants produce spontaneously to protect themselves against predators, parasites, and illness. Phytochemicals aid in maintaining optimal canine health and are advantageous in certain situations.

Beneficial phytonutrients can be found in richly colored vegetables with brilliant colors. You may have heard the term for humans known as ‘feed the rainbow.’ This term exists due to the benefits each colored vegetable contains.

Red Vegetables Serve as Antioxidants and Anti-Inflammatories

Lycopene and anthocyanins are responsible for the vibrant red color of many vegetables. Both are potent carotenoids with anti-inflammatory and antioxidant properties that protect against free radicals. 

Orange and Yellow Vegetables Help Synthesize Vitamin A

Orange and Yellow: A highly studied carotenoid found in yellow and orange-colored foods is beta-carotene. Because the body must convert beta-carotene to retinol, its usable form, it is a precursor to Vitamin A. 

Lutein, isothiocyanates, and isoflavones are abundant in green fruits and vegetables. For example, Kale has over 50 phytonutrients, including kaempferol and quercetin. Kaempferol is an antioxidant that has been demonstrated to protect the body from cancer-causing free radicals. Quercetin is another antioxidant flavonoid that has also been shown to protect the body from free radicals.  

Blue and Purple Vegetables Possess Anti-Aging and Anti-Cancer Properties

Blue and purple vegetables are high in phytonutrients, including anthocyanins and resveratrol, which have been extensively studied for their anti-cancer and anti-aging qualities. Anthocyanins are a type of antioxidant that protects cells from harm. Anthocyanins are abundant in many red and pink vegetables, but the darker the blue/purple hue, the higher the phytochemical content. 

White and Brown Vegetables are Less Vibrant Options for Phytonutrients

White and brown vegetables may not be as vibrantly colored as other vegetables, but they nonetheless contain phytonutrients. Cauliflower, like broccoli, is a cruciferous vegetable high in sulforaphane, an anti-cancer agent. Garlic belongs to the allium family of vegetables, and it contains antimicrobial and anti-inflammatory chemicals in the form of allicin and quercetin. 

The Glycemic Index (GI) is a scale that ranks carbohydrate items based on their impact on blood glucose levels. Low-GI vegetables (those with a GI of 55 or below) are digested, absorbed, and metabolized more slowly. Low glycemic veggies encourage blood glucose to rise more slowly, lowering insulin levels.

Low glycemic vegetables are excellent for a variety of phytonutrient benefits as well as fiber content. Fiber, which promotes a healthy colon and firm stool consistency, is sometimes deficient in raw diets.

Spinach is a Common Addition for Good Reason

Spinach is one of the most popular leafy greens seen in raw diets. Spinach has a high fiber content, is low in carbs, and has no starch or sugar. 

Nutrients found in abundance in spinach include:

Kale is another nutrient-dense leafy green, high in fiber, low in carbs, and free of grains and sugar. This vegetable is high in phytonutrients and essential elements that benefit your dog's health. 

Nutrients found in abundance in kale include:

Microgreens are Highly Nutritious and Different than Sprouts

Microgreens, made from various seeds, are nutrient-dense and should not be confused with sprouts. Microgreens are little, young green vegetables that are harvested between 7 and 21 days after germination. 

Sprouts, on the other hand, are newly germinated seeds with no green leaves. The nutritious content of microgreens is concentrated, which means they often have higher quantities of vitamins, minerals, and antioxidants than the same amount of mature greens.

Starchy vegetables have a higher glycemic index because they are complex carbohydrates with starch units. They can elevate blood glucose levels faster than non-starchy vegetables and are also greater in calories.

Low-fat diets necessitate an additional energy source, and dogs that cannot tolerate high-fat diets benefit from starchy vegetables. When high fats cannot be consumed, starch is converted into glucose, which the body uses as energy.

Butternut Squash Offers Sugar and Carbs But Still Has a Low Glycemic Index

Compared to other starchy vegetables, winter squash, such as Butternut Squash, has a low glycemic index. Despite having a lower GI than leafy greens, Butternut Squash has more sugar and carbs.

Beetroot has moderate starch and carbs to improve energy levels compared to other vegetables. 

Sweet Potatoes Have a High Glycemic Index, so Should Never Be Fed Raw

Sweet potatoes have a high glycemic index because of the amount of carbs they contain. Due to trypsin inhibitors, which impede protein digestion, do not feed this starchy vegetable raw. This risk is eliminated when sweet potatoes are fully cooked.

Dogs struggle to digest certain parts of vegetables, so it's helpful to prepare them in a way that makes the nutrients easier for dogs to absorb. Techniques like chopping, pureeing, or lightly steaming vegetables break down tough plant fibers, making them more dog-friendly.

For broccoli, finely chopping activates a substance called myrosinase, which converts a compound in broccoli into a cancer-fighting substance called sulforaphane. Studies suggest that chopping broccoli into tiny pieces and letting it sit for 90 minutes or more can significantly boost the levels of sulforaphane.

Fermentation is a process that uses microorganisms to break down sugars in plants, creating beneficial substances like lactic acid, vitamins, enzymes, prebiotics, and <a href="https://feedreal.com/glossary/probiotics">probiotics</a>. Fermentation enhances the taste, nutritional value, and shelf life of foods. Also, it brings health benefits for dogs, such as boosting the immune system, promoting a diverse <a href="https://feedreal.com/glossary/gut-microbiome">gut microbiome</a>, and lowering the risk of certain cancers.

Dogs do with 5-10% of their meals as vegetables.  Observing their poops will determine if you need to make adjustments in the portion size.

Not all dogs will eat vegetables. Tips for enticing dogs include dicing or pureeing them before combining them with the other food bowl components. Soaking them in <a href="https://feedreal.com/glossary/bone-broth">bone broth</a> may also work.
