The Rise of Fibremaxxing: A Modern Health Trend
Fibre has surged in popularity, overtaking protein as the favoured macronutrient among TikTok health influencers. Known as "fibremaxxing," this trend encourages followers to maximise their intake of roughage. However, experts caution that while most people should eat more fibre, excessive consumption can lead to digestive discomfort and other issues.
Historical Context and Modern Limits
Dr Emily Leeming, a dietitian at King's College London and author of the upcoming book Fibre Power, notes that our ancestors may have consumed up to 100 grams of fibre daily. In contrast, the average Briton eats only about 16 grams per day, barely exceeding the recommended amount for young children. Shockingly, just 4% of adults meet the 30-gram target set by health authorities.
Fibre is abundant in nuts, seeds, leafy greens, and beans, and it can also be taken as a supplement. Leeming emphasises that reaching the 30-gram mark offers significant health benefits, including improved digestion, reduced risk of bowel cancer and heart disease, lower bad cholesterol levels, better blood sugar control, and increased feelings of fullness.
The Benefits and Risks of High Fibre Intake
Evidence suggests that health benefits may extend beyond 30 grams, with a linear relationship observed at higher amounts. However, Leeming advises against abruptly increasing intake from 16 to 50 grams. Fibre is potent, and the gut requires time to adapt. A rapid increase can cause bloating and discomfort, while consistently consuming over 50 grams may lead to a restrictive or obsessive diet.
Moderation is crucial: An additional 7 grams daily is linked to a lower risk of heart disease, type 2 diabetes, and bowel cancer. Even a modest increase of 5 grams is associated with a 5% reduction in depression risk. Leeming stresses that there is no need to exceed recommended levels to reap these rewards.
Practical Tips for Increasing Fibre Safely
To boost fibre intake effectively, follow these guidelines:
- Increase gradually to allow your gut to adjust.
- Drink plenty of fluids, as fibre acts like a sponge and can cause dryness without adequate hydration.
- Listen to your body and ensure that your diet remains enjoyable, practical, and beneficial to your overall wellbeing.
Ultimately, while fibre is a powerhouse nutrient, balance and gradual integration are key to avoiding the pitfalls of overconsumption and maintaining optimal health.
