Antioxidants are good for your cat because they play a key role in minimizing damage to cells, including cells of the immune system.
These important, naturally occurring nutrients help maintain health by slowing the destructive oxidative process of cellular molecules. They also can be important in supporting immune responses and vaccine recognition in cats. This may be especially critical for kittens that are being vaccinated while their immune system is still developing.
Additionally, antioxidants can reverse decreases in immune-cell function for senior cats, increasing them back to healthy adult levels.
Antioxidants are nutrients found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin C, vitamin E and certain compounds called carotenoids (including lutein and beta-carotene). A blend of several antioxidants in moderate amounts may be more effective than high levels of one antioxidant.
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die in a process called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness and kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilize free radicals. More importantly, antioxidants return to the surface of the cell to stabilize rather than damage other cellular components.
When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infection.
Because antioxidants play a key role in minimizing damage to cells, such as those that make up the immune system, recent research examined the benefits of certain antioxidants on the immune response of cats. The results of these studies indicated that antioxidants are important in helping cats maintain a healthy immune system.
The research also showed that each antioxidant benefits the immune system uniquely, so one antioxidant at high levels is not as effective as a group of antioxidants acting together.
| Antioxidant | Source | Function |
|---|---|---|
| Vitamin E | Plant oil extract, tocopherols | Optimizes immune system’s T-cell activation |
| Beta-carotene | Vitamin premix, corn meal, chicken by-product meal and chicken fat | Optimizes types of cells present in the blood, increases antibody levels in the blood and optimizes vaccine recognition |
Recent research also examined the effect of aging on immune responses. The findings indicate that as cats age, immune cell responses may decline. Including antioxidants in your cat’s diet can help reverse the age-related decrease in immune cell function, returning it to healthy adult levels.
High fibre cat food has become a mainstay for many cats with gastrointestinal problems. But why is fibre so crucial for cats?
Fibre is a type of carbohydrate that isn't digested by a cat's gastrointestinal tract. It is important for cat health because it provides bulk to move food through. Some types of fibre can be fermented (broken down by bacteria) in the system. This process creates short-chain fatty acids (SCFA), which are an important energy source for the cells lining the intestinal tract.
Thus, understanding the various types of fibre and when to include fibre in a cat's nutrition plan is crucial. High-fibre cat food often contains a combination of soluble and insoluble fibres that aid gastrointestinal health and improve stool quality. Some of these fibre elements are also known as prebiotics, which are nutrients (mostly fermentable fibres) that help the good bacteria in the intestines grow.
Soluble fibre for cats, such as gums and pectins, are the best at absorbing water. These fibres are typically highly fermentable and provide the required energy source. Adding such soluble fibres to your cat’s diet can help it maintain a healthy colonic mucosa and boost immune function in the lower intestine.
Insoluble fibres, such as lignin or cellulose, have a variety of therapeutic properties and can be utilised in your cat’s meal to promote its gastrointestinal health.
Today, people are more aware of fibre and its role in their diet. Studies showing the beneficial effects of higher fibre levels in humans influence the way many people think about their own food and that of their pets. Some manufacturers now apply the recommendations of human nutritionists and make high-fibre diets for cats, but cats have a much shorter digestive tract than we do. And unlike humans, cats are carnivorous, so their nutritional needs are better satisfied with meat rather than plant matter. Therefore, cats have different dietary needs than humans. For more than 60 years, companion animal nutritionists at IAMS™ have been studying diets to meet the special nutritional needs of cats.
Furthermore, fibre-rich cat food benefit cats suffering from GI illnesses of the large intestine. Fibrous food can assist in preserving their GI motility and water balance. This is turn helps prevent constipation and diarrhea in cats.
IAMS Company research shows the optimal crude fibre level for healthy cat’s ranges from 1.4% to 3.5%. At these levels, nutrient breakdown is maximised. In unique situations, such as hairballs, higher fibre levels may be beneficial.
An important characteristic of fibre is its fermentability, or how well it can be broken down by bacteria in the intestine. This breakdown produces short-chain fatty acids, which provide energy to the intestines. Fibre varies in fermentability. Fibre 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 fibre, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk, without the negative effects of excessive stool or gas and, therefore, are beneficial in cat diets.
High moisture, protein, and minimum carbohydrate matter are all key ingredients in high-fibre cat diets. Here are some benefits of high-fibrous food for your cat:
Cats with medical issues can also greatly benefit from high-fibre foods. For instance, high-fibre wet cat food might help overweight cats in reducing overeating and lowering their risk of obesity. What’s more is, adding fibrous food to your cat’s meal will also help your pet eliminate more nitrogen through their stool, thus sparing the kidneys. In fact, many dietary fibres inhibit nutrient absorption qualities, which help to lessen the rate at which the GI tract assimilates glucose, thereby keeping the blood sugar levels stable.
High levels of poorly fermentable fibre are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS Company research shows that high fibre in cat food can make it harder to digest other nutrients in the meal and, in turn, reduce the nutritional quality of a feline’s diet. Your cat making more trips to the litter box can be a result.
Low-fibrous food contains nutrients such as electrolytes and B-vitamins that aid recuperation in cats. This type of food is usually recommended by veterinarians for cats who are prone to having a quick onset of GI disturbance. Therefore, when choosing a meal for your cat, always visit a veterinarian. If your cat is on a high-fibre diet, their veterinarian should keep an eye on them to ensure that their fibre-responsive symptoms are under control.
When choosing a pet food, fibre is an important consideration, but remember that the needs of cats are not the same as those of humans. A moderate level of moderately fermentable fibre, such as beet pulp, provides proven nutritional benefits for cats. Cat diets containing high levels of poorly fermentable fibre dilute calories and deprive cats of the nutrients they need.
All IAMS products are made with levels of moderately fermentable fibre needed to promote intestinal health. And all IAMS foods, such as IAMS ProActive Health™ Adult Original with Chicken, contain the moderately fermentable fibre system, which is the exclusive property of IAMS Company and is protected by U.S. Patent No. 5,616,569 for Pet Food Products Containing Fermentable Fibres and Process for Treating Gastrointestinal Disorders.
