March is Colon Cancer Awareness Month. I felt motivated to write on this topic b/c my late grandfather had colon cancer (CC), and also thanks to a well known gastroenterologist, Dr. Will Bulsiewicz , who talks at length on this subject.
Sadly CC is not rare and it’s often deadly. There’s growing evidence indicating that the high incidence is directly attributable to Western dietary habits. And it’s not only CC that is linked to diet. As per the WHO, research suggests as much as 30% of all cancer cases are linked to poor dietary habits, thus are preventable.
Aside from eating the right foods, in the right amounts & keeping a healthy weight, here are 3 key ways we can protect ourselves, especially against CC:
🚫ELIMINATE RED & PROCESSED MEAT (e.g. sausages/salami) - Various damaging mechanisms can come into play incl. polycyclic aromatic hydrocarbons (PAHs) generated during high heat cooking of meat, as well as nitrosamines & heterocyclic amines in cured meats, which are all strong carcinogens
🥬EAT MORE PLANTS - In a nutshell, vegetarian diets are linked to an overall lower incidence of CC - PMID: 25751512. Plants genuinely have it all - protein, carbs, healthy fats, water, vits, minerals, antioxidant polyphenols, phytochemicals & fibre. Collectively these can significantly boost our defences. Phytochemicals like curcumin from turmeric, catechin compounds in green tea & sulforaphane in cruciferous veggies may offer protective effects.
As for fibre, thanks again to Dr. Will here, a systematic review & meta-analysis of 185 prospective studies found that “fibre was significantly associated w/ reduced risk of developing colorectal cancer” PMID: 30638909. AND there’s a “dose response relationship”, whereby as fibre intake increases, so do the benefits. Every 8g of fibre correlated to an 8% reduction in CC incidence… And yet many of us still don’t get the RDI of 30g fibre a day!
👩⚕️SCREENING SAVES LIVES - CC symptoms often don’t manifest until it’s too late. Many of us know people who’ve had a pre-cancerous polyp removed upon doing a colonoscopy, which has arguably saved their life. If you think you might be at risk, chat to your doctor ASAP 💛
