Fiber is important to your dog's health, providing bulk to move food through his intestinal tract. Some types of fiber can be fermented (broken down by bacteria) in the intestinal tract. This process creates short-chain fatty acids (SCFA), which are a key energy source for the cells lining the intestinal tract.
Most people are aware of fiber and its role in their diet. The beneficial effects of higher fiber levels in humans influence the way many people think about their own food—and their pets’ food. As a result, some pet-food manufacturers began to think like human nutritionists and make high-fiber diets for dogs. But high-fiber diets and the shorter digestive tracts of dogs don't always mix well. High fiber levels in dogs can cause digestive problems and interfere with proper nutrient absorption. Unlike humans, dogs are carnivorous, meaning their nutritional needs are better satisfied with meat rather than with plant materials.
For more than 60 years, pet nutritionists at IAMS™ have been studying diets to better meet the special nutritional needs of dogs. IAMS research shows that the optimal crude-fiber level for healthy dogs ranges from 1.4 to 3.5%. At these levels, nutrient digestibility is maximized.
An important characteristic of fiber is its fermentability, or how well it can be broken down by the bacteria that normally reside in the dog's intestine. This breakdown of dietary fiber produces SCFAs that provide energy to the cells lining the intestines. Different types of fiber vary in fermentability.
Fiber sources used in pet foods include cellulose, which is poorly fermentable; beet pulp, which is moderately fermentable; and gums and pectin, which can be highly fermentable.
Research has shown that moderate levels of moderately fermentable fiber, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk without the negative effects of excessive stool or gas.
High levels of poorly fermentable fiber are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS research found that this is not a good practice because high fiber levels can decrease the digestibility of other nutrients in the food and, therefore, can reduce the nutritional quality of the diet. You might also see more poop piles in the yard because of the indigestible fiber.
The key thing to remember about dietary fiber is that your dog's needs are not the same as yours. A moderate level of moderately fermentable fiber, such as beet pulp, provides proven nutritional benefits for dogs. Diets containing high levels of poorly fermentable fiber to dilute calorie content do not provide these nutritional benefits.
All IAMS products, including IAMS™ ProActive Health™ Adult MiniChunks, are formulated with optimal levels of moderately fermentable fiber to promote a healthy intestinal tract and enhance the well-being of your dog.
Nutrients are divided into subcategories: protein, carbohydrates, fats, vitamins and minerals, and water. Regular brushing and professional cleaning can keep your dog’s teeth healthy and gleaming. Giving your pet appropriate toys to chew prevents fractures.
Common dog food protein sources include meat, poultry, fish, and some plant ingredients, such as corn gluten and soybean meal.
Protein is best known for supplying amino acids to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. It also plays a main role in hormone production.
Dogs, best fed as carnivores, require essential amino acids that are not all found in the proper balance in single plant protein sources such as soybean meal.
Common carbohydrate sources are plants and grains. Carbohydrates, also categorized as starches (sugars) and fibers, provide energy and bulk, respectively.
Starches are made up of various types of sugar, such as glucose or fructose. Through digestion, dogs can easily convert sugar into usable energy.
Fiber may or may not be fermented or broken down into short-chain fatty acids by bacteria in a dog’s intestines. Highly fermentable fiber sources, such as vegetable gums, provide high amounts of short-chain fatty acids. Moderately fermentable fibers, such as beet pulp, provide short-chain fatty acids and bulk for moving waste. Slightly fermentable fibers, such as cellulose, provide mainly bulk for moving waste through the digestive tract and only a few short-chain fatty acids.
Water is the single most important nutrient for the body. Without it, the body cannot transport nutrients, digest nutrients for energy, regulate temperature, or eliminate water.
Fats are found in meats, poultry, fish, and plant oils. Fat, for all its bad press, fulfills many vital body functions. Animal cell membranes are made of fat. Fat also helps maintain body temperature, control inflammation, and more. Fat is the primary form of stored energy in the body, providing twice as much energy as carbohydrates or proteins.
Fats also have been shown to be important in blood clotting and managing inflammation.
Vitamins are responsible for aiding functions such as bone growth, blood clotting, energy production, and oxidant protection. Vitamins A, D, E, and K require fat for absorption into the body, while vitamins such as the B-complex vitamins and vitamin C need water to be absorbed into the body.
Minerals provide skeletal support and aid in nerve transmission and muscle contractions.
