1. What happens to the gut as we age?
The gut microbiome evolves throughout our lives, from the initial colonisation at birth to the peak diversity typically reached in adulthood. However, as we age, the functionality of all our body's systems, including the gut, gradually declines. The environment of the gut microbiome changes in response to life choices and challenges, leading to an imbalance. This imbalance, often characterised by an increase in Proteobacteria—bacteria associated with harmful behaviours—can result in gut dysbiosis, making us more vulnerable to dysfunction and disease, not only in the gut but throughout the body.
Additionally, the gut wall itself loses its integrity over time due to both natural aging and external factors like damage from ultra-processed foods, pesticides, and reduced bacterial diversity caused by medications and over-sanitisation.
2. What factors impact our gut health, contributing to a decline in function and loss of vitality?
Many aspects of modern life, from our diet to our environment, can negatively affect gut health. Factors such as poor dietary choices, frequent use of antibiotics, exposure to ultra-processed foods and agrochemicals, and living in overly sanitised environments contribute to dysbiosis and compromised gut wall function. This can lead to decreased digestive efficiency, weakened immune health, and overall reduced vitality.
3. What are some simple strategies to improve our gut health?
There are both short-term and long-term strategies to support gut health. In the short term, implementing a "gut rehab" regime, such as following a leaky gut protocol, can help address immediate issues. For long-term improvement, incorporating sustainable habits like consuming more prebiotics and polyphenols can help reintroduce beneficial bacteria into the microbiome, promoting a healthier gut.
4. How can we rethink nutrition, especially as our appetite diminishes with age?
As we age, eating becomes not just about satisfying hunger but ensuring we meet our physiological needs, particularly for energy. By increasing energy expenditure through activities that promote muscle growth, we can naturally boost our appetite. While leafy greens and vegetables are excellent for the microbiome, they are low in energy and can be difficult to digest. Prioritising high-quality proteins and traditional fats, along with easily digestible foods like well-cooked root vegetables and fruits, can help maintain energy intake and provide essential nutrients, proteins, and beneficial compounds like polyphenols and prebiotics.
