Our second brain
We have a second brain in our guts. Known as the enteric nervous system, it consists of a mesh-like network of around 100 million neurons lining the entire gastrointestinal tract. These neurons include a range of cell types operating via a complex system of circuitry largely independent of the central nervous system.

These days, most people carry a drink with them wherever they go. Every food shop, however small, has a fridge packed with bottled beverages. Some people drink large quantities of sugary soft drinks, others can’t get through the day without copious quantities of coffee, and tea drinkers are happy to respond to recent experimental evidence that suggests tea is a healthy source of liquid sustenance for the human body.

Stevia is the name given to extracts from leaves of the plant Stevia rebaudiana used as sweeteners or sugar substitutes. The two main compounds responsible for the sweetness of stevia are stevioside and rebaudioside A, both of which are derivatives of the diterpene, steviol.
- Stevioside is 250-300 times sweeter than sugar, but possesses a bitter aftertaste.
- Rebaudioside A is 350-450 times sweeter than sugar and is less bitter than stevioside, making it a popular option for use in sweetener preparations.

Fresh fruit and vegetables form an essential part of a healthy diet. However, while they are undeniably good for us, their consumption may, on occasion, pose a risk to our health. The contamination of plant foods by bacteria tends to be less well known about than that of animal-derived foods, but is, nevertheless, a matter of great importance for food safety.
Bacterial contamination can affect a wide range of fruits, vegetables and other plant-derived foods, and several different species of bacteria may be responsible. Food recalls due to potential bacterial contamination have been issued for several different plant foods over the last few years, including watercress, freeze-dried sliced fruit and even a variety of herbs and spices, with Escherichia coli (E. coli) and Salmonella being some of the main culprits.
