A Better Bowl of Pet Food: Mushrooms & 5 Other Superfoods for Furry Friends

A Better Bowl of Pet Food: Mushrooms & 5 Other Superfoods for Furry Friends cover
Written by Real Mushrooms - Updated: June 14, 2024

Diet is one of the most (if not the most) important decisions you will make in the life of your pet. The old adage “you are what you eat” applies to our furry family members as much as it does to us. Are you feeding your pet a diet that supports their health and longevity or hinders it? You may be surprised to find out that what you think is a good diet might need some adjusting.

Read on... we have just the knowledge and tips you need to bring your pet’s nutrition to the next level to help them lead a longer life full of vitality. We include some general facts about the current pet food options on the market and include 6 specific foods you can find beyond the pet store that are worthy of adding to your furry friend’s diet.

The Current Pet Food Scene

There are so many food choices facing today’s pet parents. Over the past decade there has been a shift in the pet food industry. In addition to bags of dry food (kibble) and canned food, most pet stores and many groceries now offer raw, frozen and minimally processed pet food. Even some veterinary practices offer raw dog food in addition to canned and dry prescription diets.

Why this big change? Much of this shift has been driven by consumer demand for safer and healthier foods. In 2007, pet food laced with an illegal additive called melamine caused renal disease and death in thousands of dogs and cats around the world. This led to a massive recall of more than 150 brands of pet food, and was a wake-up call for many pet owners. Since then, pet parents have become more educated and proactive about animal health. More people are questioning the logic of a 100% processed diet. We wouldn't thrive if this was our diet. Why would it be different for our pets?

Pitfalls of Dry Pet Food

Here is an important fact to know if you are giving your pet dry or canned pet food:

If what you are feeding your pet is in a bag (dry kibble) it has gone through a process called extrusion Extrusion is the shaping and pressure cooking of kibble by forcing mixed raw ingredients through a die. This is done to shape the kibble. Additionally, the high heating temperatures used in extrusion kill pathogens, bacteria, mold and salmonella, and give the dry food a longer shelf life. It is a necessary process to assure kibble is safe. Canned pet food is also heated (in the can) under pressure at very high temperatures. Unfortunately, this high heating process also kills the “life” in the food. Dr. Edward Howell, in his book Enzyme Nutrition, noted that prolonged temperatures over 118* will destroy enzymes (1). The extrusion process also creates advanced glycation end products (AGE’s). These AGE’s have been shown to contribute to the development of a myriad of health conditions, including cancer (2).

Kibble is processed in a way that can lead to inflammatory responses in pets and premature aging.

Processed Pet Food & Premature Aging

Any pet food that goes through the extrusion process (as in kibble) is heated at temperatures reaching 400 degrees Fahrenheit, making the food itself inflammatory. Additionally, this high heating temperature creates the Maillard reaction.

The Maillard reaction is caused by the heating of carbohydrates and protein together which alters their molecular structure to create glycotoxins. This extremely high heating method used when making pet food also reduces the bioavailability of the vitamins, minerals and amino acids in the food (3,4).

Even more disturbing than the loss of nutrients due to high heating temperature is the creation of advanced glycation end products (AGEs) in the pet food. AGEs, also known as glycotoxins, are a group of highly oxidant compounds that have been linked to the development of many diseases including diabetes, kidney disease, metabolic syndrome and more.

In a nutshell, AGE’s have been shown to accelerate the aging process. AGEs create oxidative stress and inflammation. Testing shows an average daily serving of dog food contains Maillard reaction products at 122 times the safe level for humans and 38 times higher for cats (5,6,7).

There is also a connection between these AGE’s and osteoarthritis in our pets. A 2004 study showed that older dogs who had cranial cruciate ligament surgery had an increased level of osteoarthritis in relation to the amount of AGE's in their system. Additionally, animal studies connect AGE’s to the degradation of cartilage and the onset of joint inflammation (8,9,10).

Next steps for your pet …

Sometimes there is no choice but to feed kibble, due to availability of fresh food, financial restraints, or simply the belief that it's a better food choice. If this is the case, there are a number of things that can be done to help mitigate the effects of the inflammatory food and AGE's.

Supplementing With Fresh Food

The simple act of adding nutrient dense, fresh, unprocessed foods to your pets bowl can make a significant difference in their quality of life and ability to down-regulate inflammation. Whole food supplements such as fish oils and glandular extracts can also be helpful. Future blog posts will dive deeper into supplements.

A clinical study released in February 2022 showed that dogs fed dry food have significantly higher inflammation levels than dogs fed fresh food. The study included 2000 dogs of various breeds and ages. The data indicates that adding some unprocessed, fresh food to your pet’s bowl can be a great step in the right direction (11).

It is important to note here that these are merely suggestions, not medical advice. It is recommended that you always check with your Veterinarian before making dietary changes or adding supplements.

If you do decide to add any of the foods/herbs below to your pets diet, always start slow. If your pet has been eating the same food daily for a long time, a sudden change in diet can cause diarrhea. It is for this reason that you only want to add one new food at a time, do it slowly and monitor for any signs of loose stool. If there is loose stool, discontinue or reduce the amount of the new food or supplement.

If you cannot change your pet’s diet to entirely natural or raw food, simply supplementing their kibble with fresh foods can go a long way to improving and maintaining their health and wellbeing for the long haul.

6 Antioxidant Rich Foods & Herbs

Below is a list of high nutrient value foods that can be added to your pet’s bowl– all of these have been shown to have an antioxidant effect and also down-regulate inflammation.

Antioxidants play an important role in countering oxidative stress. When there are not enough antioxidants in our bodies, reactive free radicals can wreak havoc on our pet’s health. Additionally, a diet rich in antioxidants has been shown to have a beneficial effect on the canine brain, possibly improving cognitive function (12).

Mushrooms - Dogs and cats of all ages can benefit from having mushrooms in their diet. Mushrooms can either be cooked and added to your pets food, or you can supplement with powders or capsules. Mushrooms contain ergothioneine, a powerful amino acid and antioxidant which can support longevity. Mushrooms also contain a very beneficial antioxidant called glutathione. More detail can be found on ergothioneine here:

The modern pet supply marketplace now makes it easier to give your furry friend’s health a boost. Supplements like these mushroom extracts are geared specifically towards pets’ needs.

Sardines - An excellent addition to a dog or cat’s bowl, sardines are a rich source of an antioxidant called CoQ10. They also contain vitamin D, B12, selenium and high levels of omega fatty acids EPA and DHA, Sardines also contain the lowest levels of mercury of any fish.

Turmeric - there are an extensive number of studies pointing to the beneficial anti-inflammatory and antioxidant effects of curcumin, the active component of turmeric. In a recent study, turmeric was even been shown to be effective in supporting tendon healing (13,14).

Blueberries - Blueberries contain flavonoids, which have known anti-inflammatory and antioxidant effects (15).

Broccoli & Cruciferous Vegetables - Not only are cruciferous vegetables good for their antioxidant effect, research shows the sulforaphane in these vegetable have an effect on cancer cells in dogs. Consider adding broccoli and Brussels sprouts to your pet’s diet (16).

Beets - Beets are an excellent anti-inflammatory/antioxidant food to add to the canine diet either in fresh or supplement form. They are full of Vitamin C, B, iron, potassium, manganese, and magnesium. Additionally, beet juice has been shown to aid in exercise recovery (17).
