A cancer diagnosis can be life-altering, and it is understandable that patients and their families would want to explore all possible avenues to help manage the disease. One question that often arises is whether dietary changes, such as adopting a grain-free diet, can make a difference. While there is limited data on the specific dietary changes made by cancer patients, it is widely acknowledged that diet can play a significant role in the quality and length of life for those with cancer. For instance, it is recommended that cancer patients focus on eating balanced, healthy meals with whole grains, fruits, vegetables, and plant-based proteins to maintain a healthy body weight, which in turn reduces the risk of certain cancers.
In the case of pets with cancer, many owners also consider altering their diets, with some opting for grain-free options. However, it is important to note that there is currently no scientific proof that a grain-free diet benefits pets with cancer.

What You'll Learn
A grain-free diet may lead to heart disease in pets
While a grain-free diet is often considered beneficial for pets with cancer, there is currently no scientific evidence to support this claim. In fact, a grain-free diet may even be detrimental to the health of pets with cancer. Here are some key points to consider:
Firstly, grains are a good source of dietary fiber, which promotes gut health and helps maintain consistent stool quality. They are also an important source of carbohydrates, which provide energy for pets. By eliminating grains from a pet's diet, you may be restricting their carbohydrate and fiber intake, which can have negative consequences for their overall health.
Secondly, a grain-free diet may lead to heart disease in pets. This is a serious concern, as heart disease can significantly impact the quality and length of a pet's life. The exact link between a grain-free diet and heart disease is not yet fully understood, but it is a risk that pet owners should be aware of before making dietary changes.
It is important to note that the best diet for a pet with cancer will vary depending on the individual animal's needs. A veterinarian can provide expert advice and guidance on this matter. A high-quality diet that meets the Association of American Feed Control Officials (AAFCO) standards for complete and balanced nutrition is recommended. This includes sufficient levels of protein, fat, carbohydrates, and fiber. However, it is important to consult with a veterinarian before making any dietary changes, especially during cancer treatment, as sudden changes can cause digestive issues such as diarrhea.
While a grain-free diet may not be advisable, pet owners can take other steps to ensure their pets are receiving a healthy and balanced diet during cancer treatment. This includes providing free access to water, maintaining a healthy weight, and offering small meals or nutritious snacks throughout the day to help with appetite loss. It is also important to read nutrition labels and prepare meals at home when possible, to ensure you are aware of what your pet is consuming.

Whole grains may reduce the risk of certain cancers
Whole grains are associated with a reduced risk of several chronic diseases, including certain cancers. They are recommended as part of a healthy diet. Whole grains provide dietary fiber and nutrients such as fiber-rich bran, nutrient-packed germ, and starchy endosperm, which are not available in refined grains.
Observational population studies have linked high dietary fiber consumption from whole grains with a reduced risk of colorectal cancer. Meta-analyses of cohort studies have shown that high intakes of whole grains are associated with a 6% to 12% lower risk of cancer mortality. Dose-response analyses indicate that each 30 grams of whole grains per day is associated with a 7% reduction in cancer mortality risk.
The AICR Third Expert Report found a trend for lower breast cancer risk with increased dietary fiber from grains. Whole grains may lower cancer risk by reducing inflammation and insulin resistance, although study results are inconsistent. Observational studies have also shown that whole grain consumption is associated with less long-term weight gain, which is important as excess body fat and weight gain increase the risk of at least 12 cancers.
For site-specific cancers, meta-analyses indicate that whole grain intake is consistently associated with a lower risk of colorectal, gastric, pancreatic, and esophageal cancers. The AICR Third Expert Report also identified whole grains as a dietary choice that probably protects against colorectal cancer. Additionally, whole grains are believed to contain protective compounds such as lignans, which have been shown to decrease cancer development and growth in mouse studies.

High-protein diets may negatively impact dogs with cancer and other medical issues
While a dog's diet can play a significant role in their quality and length of life, there is no scientific proof that a grain-free diet benefits dogs with cancer. In fact, a grain-free diet can lead to heart disease in dogs.
Many commercial dog foods contain grains as they are a good source of dietary fiber and carbohydrates. Carbohydrates are an important source of energy for healthy dogs. If you are feeding your dog a grain-inclusive diet, ensure that the first ingredient on the label is protein and that the grain source is a whole grain.
Some dog owners opt for a high-protein diet for their dogs with cancer, as cancer cells thrive on carbohydrates. However, vets caution against this, as high-protein diets may negatively impact dogs with cancer and other medical issues, such as kidney failure. It is best to consult with a veterinarian to determine the best diet for your dog, as the ideal carbohydrate and protein levels can vary depending on the dog's specific needs.
It is important to note that there is currently no strong scientific evidence that a high-protein, low-carbohydrate diet provides a survival benefit for dogs with cancer. While these diets may help maintain muscle mass in thin cancer patients, a nutritionally complete and balanced diet, such as a commercial diet formulated for a dog's specific breed and age, is generally recommended. This will ensure that your dog is getting the right macronutrients (carbohydrates, fats, and proteins) and micronutrients (vitamins and minerals).

Carbohydrates are important for energy in healthy dogs
Carbohydrates are an important source of energy for healthy dogs. While carbohydrates are not considered an essential nutrient for dogs, they are a highly digestible and readily available source of energy. Carbohydrates are broken down into glucose during digestion, which is the preferred source of energy for certain body cells, including the brain. A steady supply of glucose is important as it is the only energy source that the brain and red blood cells can use.
If carbohydrates are not provided in sufficient amounts to meet a dog's energy requirements, the body will start to rely on protein as an energy source. Protein is needed for other essential functions within the body, such as growth, tissue repair, and immunity, so it is beneficial to ensure dogs are receiving energy from carbohydrates to allow protein to be used for these other functions. Carbohydrates provide the same amount of energy per gram as protein and less than fat, so increasing the amount of carbohydrate in the diet can allow for a decreased quantity of fat, which is beneficial for weight loss and weight maintenance.
Fibre is a type of complex carbohydrate that is indigestible for dogs. However, it is still important to include in a dog's diet as it is an energy source for microbes in the large intestine, which helps support the growth of a healthy bacteria population within the gut. Fibre can also help reduce the number of calories consumed by making a dog feel more full and reducing the energy density of the food.
When feeding a dog carbohydrates, it is important to choose high-quality options such as sweet potatoes, pumpkin, whole grains, oats, and quinoa. These foods are easily digestible and provide slow-release energy along with various vitamins, minerals, and antioxidants. Lower-quality carbohydrates such as corn, wheat, and white rice have a high glycemic index and can lead to spikes in insulin and quick bursts of energy followed by a slump.
While carbohydrates can be beneficial for healthy dogs, it is important to note that not all dogs with cancer respond well to high-carbohydrate or high-protein diets. The ideal diet for a dog with cancer should be determined in consultation with a veterinarian, who can advise on the best balance of protein, fat, carbohydrate, and fiber to support the dog's quality and length of life.

A grain-free diet may not improve cancer survival in pets
While a grain-free diet may be beneficial for pets with cancer who are not eating well or losing weight, there is no scientific proof that it improves cancer survival. It is important to consult a veterinarian before making any dietary changes for a pet with cancer, as a sudden change in diet can cause diarrhoea and other adverse effects.
The role of diet in cancer treatment for pets, especially dogs, has been a focus of research and discussion among pet owners and veterinarians. Many commercial dog foods contain grains as they are good sources of dietary fibre and carbohydrates for energy. However, some owners may opt for a grain-free diet, believing it to be healthier or more suitable for pets with cancer.
While there is limited data on the specific dietary changes made by pet owners after a cancer diagnosis, it is estimated that more than 1 in 5 dogs were fed a grain-free diet before their cancer diagnosis. This highlights the importance of veterinarians discussing the risks and benefits of different diets with pet owners.
It is worth noting that cancer treatment for pets can lead to fluctuations in appetite and body weight, so maintaining a nutritionally complete and balanced diet is crucial. A high-quality diet that meets the Association of American Feed Control Officials (AAFCO) standards for complete and balanced nutrition, with sufficient protein, fat, carbohydrates, and fibre, is recommended. However, not all dogs with cancer respond well to high-protein diets, especially if they have other medical concerns.
In conclusion, while a grain-free diet may not directly improve cancer survival in pets, it can be beneficial in ensuring adequate nutrition and maintaining muscle mass in thin cancer patients. Pet owners should always consult with their veterinarian before making any dietary changes for their pets with cancer to ensure a safe and effective treatment plan.
