YOU AND YOUR GUT GARDEN

 

 

 

Until recently we have known very little about the 1–2kg of bacteria, fungi and viruses  that normally live in our intestines, but in recent times there has been an explosion of new gut-related research that has revealed the huge impact these microbes have on our lives.

 

Dr Michael Mosley has written on this topic and in a recent article in the Radio Times [see link below], which is reproduced here, he summarises from his book ‘The Clever Guts Diet’:

 

“The gut is not a glamorous organ. When I was at medical school many of my fellow students wanted to study the brain or do cardiology, saving lives by studying the heart. None of my friends wanted to dedicate their life to studying the gut.

And yet our gut is central to our mental and physical health. It’s also surprisingly clever. Did you know that there is a second brain down there, known as the enteric system, that contains the same sort of nerve cells,  and the same sort of chemical nerve transmitters, as you’d find in the brain in your head? In fact, there are as many brain cells lining your gut as there are in the brain of a cat.
 

Even more impressively, there is a huge alien eco-system living down in your gut comprised of trillions of different microbes [bacteria, fungi and viruses] collectively known as the microbiome.

 

WHAT IMPORTANT TASKS DOES YOUR GUT GARDEN PERFORM FOR YOU?

 

  • Helps to regulate our body weight. The mix of microbes in your gut can affect how much energy your body extracts from the food you eat; they generate their own hunger signals; they may help decide which foods you crave; they also help to determine how much your blood sugar spikes in response to a meal. The good news is you can change your microbiome so it works with you, rather than against you.

 

  • Gut bacteria not only protect us from invaders, they also regulate our entire immune system. Over the past half-century we have seen a massive rise in allergic diseases, such as asthma and eczema, caused by an overactive immune system. We have also seen a huge surge in autoimmune diseases, ranging from inflammatory bowel disease to type 1 diabetes, which again are primarily caused by an immune system that has got out of control. There is growing evidence that changing the mix of bacteria in your gut can reduce the impact of these diseases.

 

  • Gut bacteria also take the bits of food our body can’t digest and convert them into a wide range of hormones and chemicals. These, it seems, can affect our mood, as well as our appetite and general health. Scientists are now exploring how changing your biome may help reduce anxiety and lessen depression.

 

The tragedy is that over the past few decades we have been laying waste to our microbiome and its population of beneficial microbes. Just as we have ravaged the rainforests and consigned numerous animal species to oblivion, so we have decimated the populations that live inside us. Fortunately we can help them bounce back. Whether we’re fit or sick, happy or depressed, overweight or slim, we can all benefit from taking better care of our gut garden.

 

WHAT STEPS CAN YOU TAKE TO IMPROVE YOUR GUT GARDEN?

 

  • Feed the good bacteria in your gut with the foods they like. These are known as “prebiotics”, and they act a bit like scattering fertiliser on your lawn. There are a range of foods that have been shown to be highly effective at encouraging the growth of “good” bacteria, and fortunately they are also extremely tasty. Try fermented foods — sauerkraut, kimchi and [the milk drink] kefir all contain very high levels of prebiotics. There are billions of them in a single gram of fermented food.

 

  • Cut down on sugar. Refined carbohydrates and processed foods are more likely to encourage the growth of bacteria that are bad for your health. Avoid unnecessary antibiotics, too.

 

  • Open the windows and get your hands dirty, preferably by gardening. This will connect you with the trillions of bacteria that live in the soil. It’s also the best way to ensure you get really fresh fruit and vegetables.

 

  • Make intermittent fasting part of your lifestyle. Studies have shown that this increases levels of a particularly beneficial group of bacteria called Akkermansia. Higher levels of these bacteria are linked to a lower risk of obesity and type 2 diabetes.

 

  • Reduce your stress. There is a close link between the mind and the gut and a whole new area of science, called psychobiotics, is exploring this.”
