Coffee can bug or de-bug you - in many different ways. It can actually energize your gut bugs. Nestle researchers showed that for sixteen healthy adult volunteers consuming a daily dose of 3 cups of coffee during 3 weeks. This led to an increase of the metabolic activity and/or numbers of Bifidobacterium species, important probiotics in the food industry...
All you need is love. Or failing that chocolate. And not only because dark chocolate could lower the risk of heart disease, blood pressure and sugar levels. As Dr. Schieberle's team recently discovered that heart could sense and enjoy the sweet smell of chocolate too. When they put small odor-emitting molecules from chocolate on one side of a dish, cells actually moved towards the aroma...
You are what you eat. And you smell like your food. Well, it's actually a bit more complicated - as we emit complex combinations of volatile chemicals produced from food by our own metabolic system as well as microbes that call us home. Same foods can be translated into a wide range of odors, depending on the individual.
Properly integrating and utilizing health-related information generated by sensors and genomic technologies presents a tremendous opportunity and I had an idea of how to approach the problem... Over time, the Aurametrix system evolved into something very different from food diaries, calorie counters and electronic health records. It was a way to analyze our little failures and victories, tie it to brain chemistry and cell metabolism, and contribute to a common understanding of human biology.
Our bacteria are picky eaters. Some of them - like Prevotelia - prefer a high carbohydrate diet, while others - like Bacteroides - stick to unhealthy western lifestyle with lots of meat and fat. The most prevalent bacteria in the gut of horses, cows and goats prefer people consuming alcohol and polyunsaturated fats. Methanobrevibacter is most abundant in anorexic nervosa patients. Gram negative bacillus Bilophila wadsworthia loves people with gangrenous appendicitis or those whose diets are high in milk fat. The most widely promoted prebiotics inulin and fructooligosaccharides seem to attract Bifidobacteria. What about diets low in poorly absorbed fermentable carbohydrates aka FODMAPs that seem to aggravate irritable bowel syndrome (IBS) ? Which bacteria is responsible?
