The American Association of Feed Control Officers (AAFCO) is responsible for the words "complete and balanced nutrition" on commercial pet food. AAFCO is an organization made up of people who work for state agriculture departments and the Food and Drug Administration (FDA), with input from people in front groups for industry such as The Pet Food Institute, the National Cattlemen's Beef Association and the National Renderer's Association. AAFCO is concerned with issues involving animal feed, and it advises the FDA and USDA on such matters. But it has no regulatory authority itself, it does not test pet food, and it does not issue any kind of certificate that a pet food is "complete and balanced." When that statement goes on the label, the company making the food is solely responsible for it being there. AAFCO doesn't verify.
AAFCO publishes minimum standards for "complete and balanced nutrition." But serious questions have recently been raised about those standards which may have more to do with making pet food profitable than making pets healthy. AAFCO makes no secret of the fact that it wants to cooperate with, not regulate, members of the pet food industry-an industry made up of rendering plants; manufacturers of vitamin premixes and flavorings; and multinational corporations.
Commercial pet food (pet food sold in supermarkets, pet stores, feed stores and veterinary offices in bags or cans) is a mixture of rendered (cooked) animals including road kill, unwanted animal parts such as diseased organs from slaughter houses, chicken feet, beaks, feathers and excrement. It is blended with a vitamin mix, doused with flavoring and coloring to mask the gray color,
put into a bag, box or can, labeled and sold. Except for brands that use "human-grade" meat, all commercial pet food is, literally, garbage that nobody wants. If something that resembles human food gets into commercial pet food (excluding "human-grade" pet food), it happens accidentally. Some argue that
cats and dogs do not need to eat filet mignon. That's true, but here is the problem.
Millions of animals and their owners are relying on the promise that commercial pet food is "complete nutrition." Some manufacturers even go so far as to warn people not to feed their animal(s) genuine food-only their products-as if it would be dangerous to feed little Fluffy meat and vegetables. That would suggest that pet food provides something unique and special. A glimpse behind the scenes, however, reveals that there is little science behind commercial pet food.
A good look at "complete and balanced"
It is widely accepted in the scientific community that the definition of "complete and balanced" nutrition for dogs and cats is unknown. There is a general idea of what it takes to keep most cats and dogs from developing deficiency diseases such as rickets, but the idea that a bag or a can provides "complete and balanced nutrition" for your dog or your cat is not scientifically supported. The nutritional requirements for an animal depend on its age, its breed, its condition and its environment. What works for a labrador retriever may not be right for a greyhound. Two cats put on the same commercial cat food may respond very differently. One may develop an enlarged heart from a lack of taurine, the other may not.
Researchers do not even agree how to verify "adequate" nutrition. Is adequate nutrition what will enable an animal to maintain its weight over a period of a few weeks? A few years? Is adequate nutrition what it takes to keep an animal from developing obvious deficiency diseases, such as soft bones? Or is it what it takes to keep a dog or cat from developing skin disorders, cataracts or cognitive dysfunction over the long haul? Currently, the most basic standards-like amino acid requirements-are being challenged. Things like antioxidants, methylation enhancers, mineral balance-these supplements aren't even on the map yet.
So how is it that a manufacturer can claim "complete and balance?" What are the criteria? One way a manufacturer can prove that its dog food is "complete and balanced" is to feed the product to eight dogs for six months. If six of the eight dogs make it through the study without dying of a nutritional disease or losing more than 15% of their body weight, the food is "complete and balanced."
Who created these standards? The pet food industry, working through AAFCO. And while they appear to be similar to those set by the National Research Council (NRC)-the organization that sets RDAs for humans-they are not. AAFCO standards set minimal nutritional requirements-not recommended daily allowances, AAFCO standards do not meet NRC standards which are based on 100% bioavailable, purified food. Pet food is neither, yet AAFCO requirements use the same figures in most cases. A report in the Journal of Nutrition skewers the AAFCO claim of complete and balanced nutrition. "Until the AAFCO allowances are adequately referenced citing experimental data, they lack scientific veracit. Although the
pet food industry has been given a set of tables to use to make a nutritional claim on the label, the claim lacks integrity and will remain so until measured bioavailability values are included in the calculation of nutrients allowances."
Bioavailability is a crucial issue. Bioavailability is how much of the food can actually be utilized by an animal for critical functions like the growth of cells. A bowl of chicken feet does not provide the same nutrition as a bowl of chicken thighs. The "meat" part of commercial pet food is whatever decomposing slaughter house refuse and dead animals the rendering plant took in that day. It
could be a lot of chicken feet or a few chicken feathers-not even the company that makes it can tell you what's in a can, box or bag of commercial dog or cat food.
FDA regulation of pet food
While the Food and Drug Administration can't tell you what's in a can or bag of pet food, it can tell you that it regulates it. But the public record doesn't support that claim very well. The number of times the agency has pulled pet food off the shelves to protect animals since 1997 averages out to about once a year, and those cases involved violations so blatant the FDA had to act-dioxin in over two million pounds of pet food vitamin premix; metal fragments in puppy food; aflatoxin in a million bags of corn-based dog foods (various brands using the same corn source.) These recalls are a miniscule fraction of the hundreds of millions of pounds of pet food sold in the market. What about the rest of it?
Warning letters from the FDA go out when it learns of manufacturing violations such as the wrong drug gets put into thousands of capsules or an HIV-infected knee cap enters the market. Labeling violations also provoke warning letters. The list of warning letters to pet food manufacturers since 1997 is very short. There are none.
There is, however, a series of letters to Iams, a pet food company, that look a lot like warning letters, but aren't according to the FDA. Whatever they are, they reveal much about commercial pet food.
The letters were sent to Iams regarding Iams/Eukanuba dog food. Neither the FDA nor Procter & Gamble, which now owns Iams/Eukanuba, want the public to see them. Motions have been filed in lawsuits to keep them secret, and they are not available on the FDA website. However, redacted copies we obtained under the Freedom of Information Act show that Iams and Eukanuba's dog foods did not meet
AAFCO standards even though the AAFCO stamp of approval appeared on the label.
The FDA sent the letters after being notified by Nutro, another pet food company, that feeding studies commissioned by Nutro on Iams/Eukanuba had to be stopped because dogs couldn't maintain their weight on the products. Maintaining weight is a critical issue for AAFCO-approved pet food. It's the only way to determine whether an animal is getting enough nutrients under current AAFCO testing guidelines. If the animal cannot maintain its weight on the prescribed amount of food the animal is not only getting insufficient calories, it's getting insufficient vitamins, minerals and protein as well. Iams tried to argue that its purpose for failing to meet AAFCO minimum standards was its concern over pet obesity-dogs are too fat. The company did not explain why it didn't increase the nutrients to make up for the caloric loss, nor indicate on the label that Iams is a diet food. The company also changed the numbers on the nutrient equations, and tried various other explanations as to why its food didn't meet minimal standards, but the FDA shot them down as "disingenuous."
So why didn't the food meet AAFCO standards? Probably money. When Procter & Gamble bought Iams and Eukanuba, it changed the formula of the dog foods to a cheaper recipe. Out went the meat, in went "by-product meal" (rendering plant product), Sorghum (cattle feed), and barley replaced rice. Feeding amounts were reduced 25%. When the dust cleared, these "premium" foods could compete price-wise with grocery store dog food. In fact, they were grocery store pet food with fancy labels. This is what got the ire of Nutro and Kal Kan, both of which have lawsuits against P&G's Iams/Eukanuba for false advertising and misleading labeling. A class-action suit on behalf of consumers has just been settled by the California firm of Wasserman, Comden, Casselman & Pearson. The other lawsuits are still pending.
GLUCOSAMINE PLUS for PETS - We're pet lovers, too! That is why we created Glucosamine Plus for Pets a unique blend of Glucosamine Sulfate, Shark Cartilage and Sea Cucumber the same popular ingredients found in many people products. Glucosamine Sulfate is the primary glue that keeps connective tissue and bone together and may help alleviate joint pain and discomfort. Sea Cucumber and Shark Cartilage are both excellent sources of a host of minerals and protein that may supply the therapeutic protection for joints and the surrounding tissues your pet needs. For animals ranging in weight from 5-25 pounds, give one (1) capsule daily. For animals ranging in weight from 26-50 pounds, give two (2) capsules daily. For animals over 50 pounds, give three (3) capsules daily.
AAFCO approves pet food, but it doesn't regulate it. What about the Food and Drug? What is the FDA doing to regulate pet food? One thing it is spending a lot of time on is a joint effort with the AAFCO to create an "enforcement event" targeting dietary supplements-vitamins, herbs, antioxidants. The first "target" was rumored to be glucosamine-a proven supplement for arthritis. That target was abandoned when veterinarians and others voiced major objections. New targets are planned, including MSM and garlic. "Investigators" have been appointed, and "surveillance" has been set up. An FDA/AAFCO coalition believes that launching a war against these kinds of "unapproved" supplements and additives in pet foods will protect the health of cats and dogs. They want to keep "dangerous" supplements out of pet food, but meanwhile, what's being kept in pet food?
FDA/AAFCO wants to keep "dangerous" supplements out of pet food, but meanwhile, what's being kept in pet food?
Anesthetic in commercial pet food
One additive that neither the FDA nor the AAFCO appears to be worried about is pentobarbital, an anesthetic commonly used by veterinarians to euthanize cats and dogs. The FDA has been receiving complaints from veterinarians that cats and dogs they are attempting to euthanize have developed a tolerance to the drug-it's taking more of the drug than it should to achieve euthanasia. How
could animals that had never had the drug before suddenly have tolerance to it? The most logical explanation, according to the FDA, is that they're ingesting it through commercial pet food.
Although commercial pet food manufacturers deny it, it is widely reported that euthanized cats and dogs are sent to rendering plants and made into cat and dog food. In 1997, the FDA undertook a study to determine the level of pentobarbital in commercial dry dog food and whether or not cat and dog DNA is found in such dog food. It did not find cat/dog DNA. (Another study is currently underway using different methodology that will address the same issue.)
However, the agency did find what are apparently toxic levels of pentobarbital in some food. As of this writing, the agency has not released the data from the study, (only a brief synopsis) but the agency estimates that dogs could consume up to 4 mcg of the anesthesia a day per kilogram of the dog's weight in dry dog food. An 80 pound dog could, then, get about 160 mcg of pentobarbital a day. Fifty mcg of pentobarbital per day is the limit at which the researchers did not see any effects in the eight-week FDA study. Despite finding what appears to be toxic levels of pentobarbital in dog food, the FDA states that health effects are "unlikely."
We asked Dr. William J. Burkholder if the FDA has found out what is causing the pentobarbital tolerance problem- the problem that prompted the FDA study in the first place. Burkholder is a "pet food specialist" at the FDA and a member of the "pet food committee" of AAFCO. He told us that the agency hadn't found what's causing the problem. When asked if more studies were going to be done, he
New research shows that cats and dogs respond positively to some of the same supplements we take. Lower vet bills and happier animals is our reward for optimal nutrition.
Keep them healthy
Commercial pet food is the fast food of the animal world. It's quick, it's easy, but is it really cheap? How much of what walks into a veterinarian's office is the result of poor nutrition? How many chronic diseases are caused by chronic nutritional deficiencies that accumulate over years? We can't answer those questions, but we suspect that many vet bills are traceable to poor nutrition.
Issues beyond whether an animal can simply maintain its weight or avoid an obvious vitamin deficiency are not addressed by "complete and balanced" pet food. Protection of vital organs with antioxidants and amino acids, immune enhancement, longevity and the prevention of cancer are best achieved for our "best friends" by a high-quality diet and scientifically-proven supplements.
For example, studies have shown that if an animal is given VITAMIN E and other antioxidants before it undergoes physical trauma, it is more likely to survive. Likewise, if a cat or dog gets high levels of taurine and L-CARNITINE in its diet, it is less likely to get an enlarged heart (cardiomyopathy). The same amino acids given as supplements can also reverse heart conditions if they do occur. Probiotics can potentially protect dogs and cats from killer bacteria like salmonella, and provide a good source of B vitamins. And although cats can't convert BETA-CAROTENE to vitamin A, they can use it to enhance their immune systems. These are only some of the ways our "best friends" can benefit from the same high-quality nutrients that protect us.
Jack the cat was living the good life in Hollywood and seemed to have the world by the tail until the day he couldn't move and stopped eating. His alarmed owner rushed him to the veterinarian where he was told that Jack had serious kidney problems and nothing much could be done. No reason could be identified Jack's condition at six-years-old, young for a cat which can live 20 to 30 years. Jack's owner refused to give up, however, and took his faithful friend to another vet for a second opinion. The second vet was trained in both traditional and alternative veterinary medicine.
When Jack landed on the examining table, he was anorexic and anemic. About half his body mass had disappeared. The laboratory test results were grim. Jack's creatinine and BUN (blood urea nitrogen) were ten-times normal. An ultrasound showed bloated, water-logged kidneys. The veterinarian didn't have much hope, but offered to do surgery to clear any potential blockage and get a better grip on the situation. Jack's owner agreed, and a biopsy was taken during the procedure.
Life Extension Animals Case Studies
By Terri Mitchell
It was five long days until the results came back. By then, Jack was barely hanging on. The report showed that Jack's kidneys were inflammed for no apparent reason. Little grains created by the immune system were filling up his kidneys, blocking the delicate filtering system. Something was needed that could counteract the inflammatory process. The vet decided that Jack needed an intensive program starting with N-ACETYLCYSTEINE (NAC).
NAC is a form of the amino acid, CYSTEINE, with multiple kidney-protective actions. The research on what NAC can do for the kidney (and the liver) is scientifically well-documented. In one recent study, researchers in Italy demonstrated that NAC normalizes creatinine levels in rodents with kidney failure. It reverses inflammation and restores filtration. Similar findings are reported by French researchers when NAC is given as a pretreatment before experimental kidney damage in rats. Without NAC, there is a 68% reduction in the ability of the kidneys to do their job. With it, the loss of kidney function is only 29%. A third study confirms that an infusion of NAC before and after experimental kidney damage doubles the kidney filtration rate. NAC is strong medicine for the kidneys. It has no adverse side effects, even when small animals like cats are given a human dose.
The veterinarian started Jack on 100 mg of NAC twice a day, plus a new diet of raw beef and chicken and 100 mg of DHEA (dehydroepiandrosterone). DHEA is critical for an important kidney enzyme known as sulfotransferase. People with kidney disease have depleted levels of DHEA. Research shows that DHEA and NAC probably work synergistically, which is why they were given together.
Within 24 hours of receiving NAC and DHEA, Jack began eating like a normal cat. He continued to vomit for several days (a side effect of kidney failure), but two weeks from the date of surgery, his BUN had dropped from 152mg/dl to 45.6mg/dl and he was up and around. At that point, the supplements were cut in half. A month later, Jack's blood tests were normal. That was over a year ago and Jack is still doing great. He is maintained on a high-protein diet along with 50 mg of NAC and 25 mg of DHEA a day.
Zoe, the hairless dog
Zoe was beginning to look more like a chihauhau than a Yorkshire terrier. The little dog belonging to Lynne and Frank Burger scratched at her back constantly, but nothing they did seemed to help. She was going bald. And not only that, she never wanted to play with her buddy, "Mr. Pug," anymore.
She seemed to have nervous energy but no real energy. Smallest in a household of ten dogs, Zoe had a special treat added to her dry food: a "gourmet" food from the grocery store.
"Flea allergy" or "food allergy" is a common diagnosis for animals losing their hair. It's a quick, eye-ball diagnosis rarely accompanied by laboratory tests. The cure is usually steroids plus one of the new pesticides that is put on the back of the animal and absorbed through the skin. The problem is that fleas are only one of many things that can cause hair loss, which is usually accompanied by some sort of skin disorder.
Researchers from Hungary recently reported that 17 dogs treated with pesticides, "restricted diets," steroids, antibiotics and other medications did not respond because they were infected with microorganisms that are not usually regarded as a problem. Yet when the bugs were eradicated with the proper drugs, the dogs got well. This points out the importance of finding
the root cause of a persistent problem.
COAT & SKIN - You can usually tell an animal's health by the condition of its coat and skin. Puritan's Pride Coat and Skin is a potent formula that can correct dry skin conditions, and promote a glowing coat and healthy skin. Coat and Skin provides vitamins A, D and E plus pure natural unsaturated oils essential to your pet. Give your dog the benefits of this carefully formulated health aid.
Another cause of hair loss is poor nutrition. There is considerable evidence that the nutritional requirements for dogs depends on the breed (This is especially true of purebreds). It appears that dogs prone to certain disorders also require certain dietary needs. English setters, for example, can inherit a terrible disease called Batten disease which causes the brain to shrink. It is accompanied by abnormally low levels of polyunsaturated fatty acids and the amino acid, L-CARNITINE. Researchers at Indiana University wanted to see if it would help to supplement the animals diets' with carnitine, fish and corn oil. It did. Carnitine greatly reduced cognitive decline, and the combination reduced brain atrophy and extended lifespan 10%.
In 1988, veterinarians at the University of California at Davis reported on 13 dogs that had been eating a generic dry, corn and wheat-based dog food. The dogs were depressed and lethargic. They had swollen lymph nodes and, worst of all, they had scaly, crusting areas where their fur was falling out. The dog food the owners were feeding did not state that it met minimum nutritional requirements (AAFCO). When the animals were put on a higher-quality dog food, the animals began to get better within days.
Aging and dementia in dogs
Elderly dogs can act like elderly people who aren't quite "with it." The "not with it" part is caused by damage to brain cells-damage that accumulates over time. A small percentage of dogs can go on to develop an Alzheimer's-like condition. (Although under the microscope, doggie AD does not have all of the same features as human AD.) Symptoms of brain aging in dogs include sleep disorders, forgetting house-training, lethargy, disinterest, confusion about going in or out of doors, hiding and getting lost.
There are various supplements an owner can give their animals to protect them from degenerative diseases. DHEA drastically with age. In a study from Purdue University, 100 mg/kg of DHEA a day given as a supplement for seven months to elderly dogs reduced the percentage of brain cells with extensive DNA damage by 42%. This shows that even an elderly animal can benefit from anti-aging interventions. In the same study, damage to the dogs' immune cells was cut in half. This is good health news for pet owners. Note that both types of cells (immune and brain) are extensively damaged in people with Alzheimer's disease. Its antioxidant action may account for DHEA's ability to protect these vital cells.
There are other methods to protect the brain as well. When the Science Diet© people went looking for a supplement that could help aging dogs stay alert, they focused on two important aspects of brain aging: energy and free radical damage.
The brain's energy is generated by sub-cellular structures called "mitochondria." When mitochondria make energy, free radicals are created. If the lymphatic system is ineffective in draining away free radicals, then they damage mitochondrial DNA. Damaged DNA, in turn, prevents the intracellular activity (little power plants) from producing energy efficiently. The vicious cycle is accelerated by age.
The brain is very susceptible to free radical damage because of its high fat content and high demand for energy. One of the most powerful brain antioxidants is Alpha Lipoic Acid, also known as lipoic, or thioctic acid. lipoic acid has multiple actions. On one level, it restores and maintains other antioxidants including vitamins C and E, and the natural antioxidant, glutathione, which is diminished in the brains of elderly dogs. Lipoic acid also enhances the level of coenzyme Q10, an energy-related enzyme, and restores arachidonic acid in brain cells to youthful levels. Arachidonic acid is absolutely critical for learning and remembering. Researchers have demonstrated that restoring arachidonic acid to youthful levels through supplements increases the ability of neurons to respond. In other words, arachidonic acid may be the key to teaching an old dog new tricks.
Additionally, lipoic acid can chelate iron and other metals, keeping them from fueling free radical chain reactions. By itself, lipoic acid is highly protective of brain cells, but there is another element that can be combined with it that makes it even more powerful: L-CARNITINE
Scientifically-proven anti-aging combination
Carnitine is an amino acid that has a special role in energy production. It transports fuel into mitochondria for conversion to energy-ATP. Carnitine levels decline with age, and so does its transport. By supplementing with carnitine, studies show that old mitochondria can have the energy production of young mitochondria. In a stunning report that was published in the Proceedings of the National Academy of Science, researchers at the University of California at Berkeley showed that elderly rats given L-CARNITINE doubled their activity to a level approaching that of young rats. (Young rats given L-CARNITINE were like five year-olds on jet fuel - i.e. 5 year old humans). Researchers were able to correlate increased activity with increased energy production in the animals' mitochondria.
As great as it was to get the old mice up and going again, their increased energy came with a price: a 30% increase in free radicals. This is where lipoic acid comes into the picture. When the same researchers added lipoic acid to the L-CARNITINE supplements, oxidative stress was reduced to the level of youngsters and physical activity was even greater than that achieved with lipoic acid alone. Memory was enhanced, and when the researchers looked at the hippocampus-a brain structure having to do with memory-they found that the combination of L-CARNITINE and lipoic acid actually kept the mitochondria from aging.
CALMING FORMULA for DOGS - Calming Formula is recommended for dogs exposed to increased environmental stressors. It is an advanced formula that contains a combination of factors that help to reduce behavioral problems associated with stressful situations.
For years nobody paid much attention to the diets of their cats and dogs. They got the scraps off the table, or the mice from the barn and that was about it. But when these animals began being used in laboratories, it became imperative to know their nutritional requirements. "Complete and balanced nutrition" pet food is a billion dollar offshoot of "lab chows." The industry has contributed substantially to understanding the nutritional requirements of our "best friends." But science is moving on now, beyond what it takes to keep an animal on its feet, to what it takes to keep an animal healthy in the long run. New research shows that cats and dogs respond positively to some of the same supplements we take. Lower vet bills and happier animals is our reward for optimal nutrition.
