Traditional Chinese medicine places the Spleen and Stomach at the centre of digestion. Learn how fermented foods are viewed in this tradition and how to include them thoughtfully.

The centre of the body in TCM

In traditional Chinese medicine (TCM) theory, the Spleen and Stomach sit at the centre of the body, both physically and symbolically. Traditionally they are described as transforming food and drink into Qi and blood, the substances thought to nourish every other organ system. Because of this, TCM has always paid close attention to what and how we eat.

Warm, cooked and easy to digest

TCM dietary advice tends to favour warm, cooked meals, eaten at regular times and without rushing. The Spleen is traditionally said to dislike excess cold and damp, so very cold drinks and large amounts of raw food are often kept to moderate amounts. Fermented foods fit into this picture in an interesting way: fermentation partly breaks food down before it reaches the plate.

What science says about gut microbes

Modern researchers describe the gut as hosting a vast community of microbes. Work such as the Human Microbiome Project has mapped these bacteria, and studies continue into how they relate to digestion, mood and general wellbeing. Diet, antibiotics and lifestyle can all change their balance. The research on specific fermented foods is still developing and results vary.

Fermented foods you might try

• Yogurt with live cultures, perhaps at room temperature rather than straight from the fridge.
• Kimchi, as a small side serve with a warm meal.
• Sauerkraut, added to cooked dishes at the end so it stays crunchy.
• Fermented black beans, a traditional Chinese seasoning for stir-fries; they are cooked, so they are valued for flavour rather than live bacteria.

Talking it through

At Lane Cove Acupuncture, inside the Lane Cove Healing Centre on Longueville Road, diet is part of the conversation in a consultation. Some people choose acupuncture and Chinese herbal medicine as a complement to medical care. If you have a digestive condition, are pregnant or trying to conceive, or take medication, please check with your GP or a dietitian before changing your diet, and keep them informed.
