Whilst we feel that you should be able to get all the nutrients you need from the food in your diet, the modern food supply chain and the sale of groceries by large supermarket chains has altered our diet dramatically. Advances in shelf stability and the global distribution of mass food production means that the nutritive value of our diet has diminished.
The typical modern western diet consists predominantly of ‘food-like’ substances, and includes large amounts of unhealthy types of fats, added sugars, artificial preservatives, colours, flavours, stabilisers and fillers, low quality salt, a high intake of poorly farmed animal-sourced protein, and refined carbohydrates. It is not surprising that this has impacted the composition patterns of the human microbiota. It is these diet and other lifestyle factors that have induced changes to the proportion and diversity of bacterial species within the microbiota.
You can make significant improvements to your overall health by altering your diet, what you eat influences your microbiota more than any other single factor. For a healthy gut eco-system you need a diverse, fresh, seasonal, whole food diet. It sounds simple but living in a modern urban society at a frenetic pace makes this a considerable challenge.
Vegetables contain high quantities of plant fibre which can’t be digested by humans, but feed our beneficial gut bacteria. Instead of eating ‘food-like’ substances you should be eating larger portions of fresh fruit, vegetables, whole grains, legumes, nuts and seeds because they contain fabulous fibre, and are as nature intended.
