 Processed Meats and Colorectal Cancer: What You Need to Know

When we think about reducing our cancer risk, we often hear about quitting smoking, limiting alcohol, and staying active. But there’s another important — and often overlooked — factor that deserves our attention: processed meat.

We’re now seeing a rise in colorectal cancer (CRC) among younger adults, not just older populations. That means it’s time to look more closely at everyday dietary habits that may contribute to risk — including that regular serving of bacon, ham, or sausages.


What the Research Tells Us

A growing body of scientific evidence shows a clear link between processed meat consumption and increased risk of colorectal cancer. Processed meat includes any meat that’s been altered for preservation or flavour — think salting, curing, fermenting, or smoking.

In fact, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classifies processed meats as carcinogenic to humans. That means there is strong evidence these meats can cause cancer, especially colorectal cancer.

One large UK study found that eating just 70g of red and processed meat per day was associated with a 40% increased risk of colon cancer. Another 2025 study involving over half a million women found that just 30g of processed meat daily was enough to raise CRC risk by 8%.

Why Processed Meats Are Harmful

So, what’s the problem with processed meats? It’s not just the meat itself — it’s the compounds that are added or formed during processing and cooking:

  • Nitrates and nitrites used in curing form N-nitrosamines, powerful cancer-causing agents.
  • Heterocyclic amines form when meat is cooked at high temperatures.
  • Polycyclic aromatic hydrocarbons from smoking or charring can damage DNA.

These compounds can work together to disrupt gut health, trigger inflammation, and increase the risk of DNA damage — all of which play a role in the development of colorectal cancer.

So, What Can You Do?

The World Cancer Research Fund recommends limiting red meat to three servings per week — and processed meat? Ideally, very little, if any at all.

If you’re someone who enjoys bacon or deli meats regularly, start by making small changes:

  • Swap in plant-based or whole-food protein sources like legumes, tempeh, or eggs.
  • Choose fresh, unprocessed meats and cook them gently (e.g., stewing, baking, or slow-cooking rather than grilling or frying).
  • Make vegetables and fibre-rich whole foods the stars of your meals.

We don’t need to eliminate these foods completely, but we do need to pay attention to frequency, portion size, and preparation methods. Remember — prevention is powerful, and even small changes can make a meaningful difference over time.

If you’re experiencing digestive symptoms, fatigue, or simply want to understand how to eat healthier, let’s talk. Holistic healthcare offers powerful support for prevention and healing — from food and lifestyle to gut health and mindset.

 Walk Your Way to Better Mental Health: How Daily Steps Can Reduce Depression


We often hear that staying active is good for our physical health, but did you know that simply increasing your daily step count could also support your mental well-being?

A recent systematic review and meta-analysis examined data from nearly 100,000 adults and found a clear link between higher daily step counts and fewer depressive symptoms. 

Key Findings:

  • Taking at least 5,000 steps per day was associated with fewer depressive symptoms.                   
  • Walking 7,000+ steps per day was linked to a reduced risk of developing depression.
  • Even small increases—an extra 1,000 steps per day—were associated with a lower risk of depression.                       
  • The mental health benefits of walking applied across all age groups and genders.

What This Means for You:

The good news? You don’t need to hit 10,000 steps a day to see benefits. Simply moving more—whether through walking, dancing, or even pacing while on the phone—can make a real difference in your mental well-being. If you’re feeling low, consider setting a step goal and making movement a regular part of your routine.

This study highlights how step-based physical activity could be a simple, accessible, and effective way to support mental health. So, lace up your shoes, take a walk, and step towards better well-being—one stride at a time!

The Not-So-Humble Dragon Fruit


Surely no fruit says 'I am super yummy and healthy' more than dragon fruit - just look at that deep rich colour!
This humble little cactus fruit packs a punch when it comes to nutritional benefits including: 
  • A rich source of antioxidants betacyanins and betaxanthins which 'mop up' damaging free radicals and help to lower the bodies inflammatory load.
  • Have a positive effect on fasting plasma glucose levels, and encourage the growth of pancreatic cells. Therefore may assist with managing healthy blood glucose levels.
  • Rich source of magnesium, calcium, vitamin C, potassium, and fibre.
  • Source of oligosaccharides which act as prebiotics feeding beneficial bacteria in the colon.
  • The seeds are a source of omega-3 and omega-6 fatty acids. 
I don't know about you but everything about this fruit screams 'get in my belly!'.

Food Intolerance Case Study From My Clinic

There are two words which come up in my clinic often: Food Intolerance. Food intolerance is an inflammatory response to the ingestion of a food substance.

I spend a lot of time in my clinic looking for ways to reduce the ‘inflammatory load’.

Why?

Because I am hard-pressed to think of any condition that is not caused or made worse by inflammation.

I thought I would share with you a real case from my clinic to illustrate the influence of underlying food intolerance on health and wellbeing.

Please note, the client has given permission for their case to be shared, however all personally identifying information has either been changed or omitted to protect their identity.

Client: adult early twenties.

Main presenting issue: diagnosed keratosis pilaris with bumps covering 90% of facial cheeks, arms, and thighs. The bumps are a mix of red, white-head, and skin-colour in appearance.

Other factors of note: generally, in good health. Experiences mild hayfever on occasion and bad breath.

History: Client cannot remember a time when they did not have keratosis pilaris which has become worse over the years. Has tried daily moisturising and steroidal creams on the advice of their Dr, however these provided only temporary relief. Was given antibiotics a couple of times when young but otherwise has not had them much since. Both parents have a history of reactive inflammatory issues (allergies, hayfever, food intolerances).

Keratosis pilaris is a benign inflammatory condition which causes tiny pimple-like bumps generally on the arms, thighs, buttocks, and cheeks. This condition is considered incurable, more common in children, and likely to resolve on its own by 30 years of age.

Naturopathic treatment: administered the FIT 130 food intolerance test, a scientifically valid and reliable measure of an individual’s inflammatory response to 130 different foods (including yeast). Results from this test identified two foods to which the client was highly reactive – both which were eaten daily by the client. The client was instructed to remove these two foods completely from their diet for one year. Several other low reactive foods were identified and placed in the diet on a rotation basis. I also discussed basic healthy diet guidelines with the client. No supplements were given.

Follow up at 2 weeks: client was struggling to completely remove one of the reactive foods from their diet, we identified which foods this item was likely to be in, acceptable alternatives and where to source them. No change at this point in the keratosis pilaris observed.

Follow up at 4 weeks: client managed to completely remove the two highly reactive foods and was following the rotation guidelines. No change in the keratosis observed.

Follow up at 8 weeks: Client was very happy, there was approximately an 80% improvement in the keratosis pilaris. Client reported a couple of occasions when they consumed small quantities of one of their highly reactive foods, otherwise they were managing well.

Follow up at 12 weeks: Client’s facial cheeks were completely free of the kerotosis bumps which they were very happy about. There were still some bumps remaining on the arms and thighs, however an overall 95% improvement was observed since the initial appointment. Client reported they consumed small quantities of one of their highly reactive foods on a few occasions but otherwise were sticking to their treatment well. At this point I introduced two supplements: a prebiotic and a substance which stimulates the body’s natural anti-inflammatory/ antioxidant processes.

Follow up at 6 months: Client presented with complete recovery from kerotosis bumps, in addition they reported general skin improvement, ‘a great improvement in hayfever’, and an overall improvement in their general sense of health and wellbeing.

Conclusion: It appears in this case the client’s keratosis was related to an inflammatory response. Identifying and removing foods which were driving inflammation assisted in reducing their overall inflammatory load and eventual resolution of the keratosis pilaris. Interesting isn’t it.

Things to Consider: 
Improvement did not happen straight away, changes occurred slowly over several months. Clients often expect one appointment will lead to a resolution of their issues; I have only ever seen this occur once in my almost 20 years as a Naturopath. It takes time for dysfunction to set in, and it takes time to reverse that dysfunction.
The client stuck to their treatment and kept with it over time which is why they experienced improvement. The biggest hindrance to improvement I witness in clients is not following treatment.
The client presented with a long-standing condition (15+ years), however their presentation was relatively simple. Most often as Naturopaths, we see clients with long-standing complex presentations which require complex and long-standing care to support and/or correct. In such cases it is unlikely that one or two appointments will achieve anything significant.

Naturopath Appointments From the Comfort of Your Own Home

COVID-19 Update

I have made the decision to move all consultations online from this point forward until the current pandemic is resolved.

You can still access Naturopathic appointments online from the comfort of your home using a variety of means such as phone, Skype, and face-time calling through Messenger. These platforms are free to use, easily accessible, reliable, and I currently use them with clients successfully.


In addition, my clinic offers an online dispensary service whereby prescriptions are filled and paid for online and sent directly to your doorstep. No need to leave home. I have been offering this service in my clinic for several years now and have been assured my clients will continue to receive the same high standard of service I have come to expect.

From a Naturopathic perspective, there is much you can do to both strengthen your resistance and immune response in the face of COVID-19. I have spent much of this past week reviewing the scientific literature on effective nutrients and herbs for COVID-19. Of course, given this is a new coronavirus strain, there currently is no COVID-19 vaccination or specific drug treatment available. However, there is a body of evidence supporting the use of specific nutrients/herbs for other coronaviruses, and indeed in some instances, these have been employed by hospitals and governments successfully in other countries. Be aware that whilst there is much information circulating on the internet, not all are accurate and I urge you all to be wary when following advice from bloggers, google searches, personal success stories, or chat groups in the absence of professional input. 

I am offering 30 minute online/phone consultations to discuss your nutrient and herbal support options during the current pandemic. Book an appointment with me either by phoning me on 0431 896 937 or through the 'Contact' tab above. 

Warm Regards,

COVID-19 Announcement

Due to the current pandemic, I am writing to keep you informed of operations within Catherine Clark - Integrated Health. 

Supporting the health and well-being of everyone is my upmost priority during this time, and it is for this reason that I have decided to make the following temporary changes (based on Government recommendations) to my clinical practice. These include:

  1. Increased efforts to thoroughly disinfectant all relevant surfaces on days when the clinic is open - door handles, tables, chairs, equipment etc..
  2. Use of paper hand towels in the bathroom.
  3. A hand sanitiser is readily available and I ask that you use this sanitiser upon your arrival. 
  4. If you are experiencing any cold or flu-like symptoms (fever, cough, sore throat), please contact me to arrange an online appointment, rather than attending your appointment in person. 
  5. I encourage online/phone appointments during this time as a viable alternative to face-to-face appointments. 
  6. If you have returned from overseas travel, have been in contact with an infected person, or are experiencing symptoms such as fever, cough, sore throat, please follow the governments recommended two-week isolation period. 
Given the circumstances are presently changing at a rapid pace, I will endeavour to keep you posted should any further changes be needed. 

The present situation is a difficult time for small business/ sole traders. Government assistance efforts do not offer any support to individuals who make their living in the manner that I do. I urge you to please continue to support your local small business during the following months. 

In addition, now is an important time to not only practise self-care but also to actively care for one another. As I am sure you have all witnessed, there has been much 'panic buying' at the supermarkets which has resulted in a shortage of available supplies in some areas. I have observed a similar effect regarding practitioner supplement supplies. I ask for patience during this time and an understanding that alternatives can be sourced. 

Warm Regards,
Catherine

Self Care: Self Harm

On Sunday evening (10th February) the current affairs program 60 minutes aired a piece called ‘Trick or Treatment’, which examined extreme reactions to products, some of which are not listed on the Australian Register of Therapeutic Goods (ARTG). Australia has one of the strictest and most developed regulatory systems regarding the manufacture of complementary medicines in the world. The ARTG takes a risk-based approach with a three-tiered system (exempt; low risk and high risk) for regulating all medicines (including complementary medicines). The majority of complementary medicines are listed as low risk on the ARTG. With this in mind it is important to note that some of the products mentioned were not listed on the ARTG and all were not prescribed by a suitably qualified health professional.

Self-prescribing is unfortunately something I commonly see. I strongly recommend consumers to always seek advice from an accredited practitioner before taking any complementary medicine. As an Australian qualified and registered Naturopath, herbalist and nutritionist, I adhere to strict quality and ingredient laws which is why I almost exclusively recommend ‘practitioner only products’.

When using complementary medicines always:
  •     Seek professional advice and remain under professional care whilst taking complementary        medicine;
  •        Use ARTG listed products only;
  •        Follow the label/prescription instructions and warning statements.

To add some balance to this story, it should be noted that more than 600, 000 Australians present at hospital each year as a result of medication errors, inappropriate use, misadventure and interactions. According to the Medicine Safety: Take Care report developed by the Quality Use of Medicines and Pharmacy Research Centre at the University of South Australia, the yearly cost of medicine-related problems in Australia exceeds one billion dollars.

The Pharmacy Research Centre President, Dr Chris Freeman stated:

‘If medicine harm was a chronic disease it would already be a national health priority. This report highlights that governments, pharmacists and other health professionals need to work together to reduce the alarming incidence of medication errors, misadventure, misuse and interactions.’ https://www.psa.org.au/wp-content/uploads/2019/01/PSA-Medicine-Safety-Report.pdf

What the Medicine Safety report highlights is the significant adverse effect on humans of using prescribed and regulated medications, the prevalence of which far exceeds that of complementary medicines. The study further points out that half (50%) of these adverse reactions could have been prevented, suggesting that human error may have been involved. It's important to acknowledge here that biochemically speaking, the human body can be highly nuanced. Put simply, something which is safe and beneficial for the vast majority can be poison for a particular minority. Predicting which individuals fall into that minority can sometimes be like finding a needle in a haystack - seemingly impossible to find until you accidentally get poked.  

I guess the take-home message is to always seek professional guidance when taking any type of medication and remain under the care if that professional whilst you are taking it. 

Finally, I do hope you continue to enjoy the benefits of complementary medicine in a safe and supported manner, and also that you enjoy this glorious day x.
