Nourish Your Inner Garden and Lower Your Risk of Cancer

WINNIPEG – What we eat, weigh, and expose our body to all influence our health, as can sleep, exercise, and stress. In previous articles, I presented some of the most important things you can do to not only decrease the risk of developing cancer, but also to help fight the disease and prevent recurrences.

Part 1 covered five actionable steps you can take that have been shown to improve health and reduce the risk of cancer: (1) stop smoking, (2) breathe clean air, (3) avoid junk food, (4) maintain a healthy weight, and (5) eat more vegetables and fruits. In part 2, I outlined three more: (6) reduce inflammation, (7) use healthier cooking methods, and (8) know what to cook and why. In last month’s article, I covered three additional vital steps including (9) getting more exercise, (10) getting better sleep, and (11) taking appropriate supplements.

This month outlines the importance of fermented foods, probiotics, and prebiotics.

(12) Boost good gut microflora.

The old saying “you are what you eat” has never been more true, but in recent years the role of good bacteria and human health has been a major focus of medical research. The database of biomedical citations and studies Pubmed lists over 2,000 publications focused on this burgeoning research area. Our gastrointestinal (GI) tract is home to trillions of microorganisms including fungi, viruses, and bacteria, which are called the gut microbiome. Through the promotion of digestive enzymes, vitamins, and short chain fatty acids, our gut microbiome is a major contributing factor in the process of achieving optimum health and wellness.

Specific strains of friendly flora have been shown to improve vaginal, urinary tract, and oral health, working to reduce and prevent ear, nose, and throat infections, urinary tract infections, bacterial vaginosis, and yeast vaginitis. In addition to reducing the risk of developing cancer, studies have shown that those with a diverse, healthy microbiome also respond better to cancer treatment.

Diet, age, disease, drugs (including antibiotics) and stress all negatively affect our gut bacteria. An imbalance of “good” gut bacteria vs. too much “bad” bacteria is called dysbiosis and is associated with inflammatory bowel diseases, irritable bowel syndrome, diabetes, obesity, cardiovascular disease, bone loss, inflammation, depression, anxiety, and cancer.

Probiotics, which means “for life,” are live microorganisms that when consumed at sufficient levels provide a health benefit. Normally, there should be a healthy balance of good bacteria (probiotic), and bad bacteria (pathogenic), but health problems, poor diet, antibiotics, and many prescription drugs can lead to dysbiosis. Regular consumption of fermented foods, and avoiding the drugs and foods that can have an adverse effect on our gut microbiome can shift the “balance of power” towards the good bacteria, helping to reduce the harmful effects of the pathogenic strains.

I recommend eating fermented foods which are naturally high in probiotics including kimchi, sauerkraut, yogurt, and kefir. To further boost the benefits of probiotics, eat foods high in indigestible soluble and insoluble fibre. The fibre acts as a “prebiotic” that feeds the probiotic bacteria in the small and large intestine. Just a few of the foods high in prebiotic fibre include chicory root, onions, leeks, asparagus, barley, oats, apples, flaxseeds, seaweed, sweet potato, berries, avocado, and legumes. Green bananas are another good source of prebiotic fibre. The resistant starch in bananas is converted to sugar when they’re allowed to ripen, so it’s best to eat them green to preserve the prebiotic effect.

Resistant Starch

When you cook starchy foods like potatoes, rice, and pasta, the starch molecules absorb water and swell. When the foods are cooled after cooking, the molecules crystallize and become less digestible. This “retrogradation” process transforms the starch into “resistant starch”, and it converts into a prebiotic in the large intestine. This process increases beneficial bacteria, including a strain called Bifidobacterium which manufactures short-chain fatty acids and vitamin K2.

Unlike other starches which turn to sugar in the small intestine, resistant starch resists digestion in the stomach and small intestine and provides food for good bacteria in the large bowel. Resistant starch has been compared to a “super-fertilizer” or compost for boosting healthy gut bacteria, leading to improvements in just about every aspect of human health. It boosts your metabolism, promotes balanced blood sugar, and improves gut microflora, which can all help promote weight loss.

When we consume resistant starch, butyrate is formed in the large intestine. It’s one of the most important short-chain fatty acids, with powerful anti-cancer effects. A major energy source for colon cells, butyrate helps lower blood sugar levels, repair leaky gut, and slow down carbohydrate digestion. It increases levels of leptin (a hormone that reduces appetite) while decreasing ghrelin (the hormone that triggers hunger).

Probiotic Supplements

Look for probiotics that incorporate natural fermentation in their production process, including Dr. Ohhira’s (the world’s best-selling probiotic, produced in Japan through the fermentation of various fruits, vegetables, mushrooms, and seaweed). Other quality supplements include New Beginnings from Olie Naturals (a liquid fermented probiotic supplement from Denmark), and Metagenics products that contain clinically-proven strains. Don’t be persuaded by products hyping billions of colony forming units in their marketing. When it comes to probiotic supplements, it’s not the quantity that matters, it’s the strains.

Prebiotic Supplements

Three of my favourite prebiotic supplements are Fiberrific, a tasteless soluble hydrolyzed inulin powder derived from chicory that dissolves completely in water; XOS, a “xylo-oligosaccharide” chewable soluble fibre prebiotic; and MSPrebiotic, an insoluble superfine tasteless resistant potato starch powder that can be added to smoothies, green food drinks, or simply a glass of water. These products feed and amplify the healthy bacteria of our gut microbiome. Research indicates that combining both soluble and insoluble prebiotics may provide a more effective synergistic health benefit, as each type works in different areas of the colon. I’ve had clients with a variety of GI and digestive issues that have experienced relief by combining a quality probiotic supplement with a soluble and insoluble prebiotic supplement.

Quality probiotic, fermented foods, and prebiotics will nourish your “inner garden” and promote a healthy microbiome, bringing many lasting health benefits and reducing the risk of cancer.
