Tryptophan in food: Will it make you happy, sleepy or smelly?
by Aurametrix team in Irritable Bowel Blog
And the answer is ... either or all of the above. And this is not a complete list of all that can happen. In some rare conditions, for example, tryptophan could also make your pee purple.Tryptophan supplements were used as a popular sleeping aid until negative press in 1989. The FDA banned dietary tryptophan supplements from the market, just days before the arrival of Prozac rising as the new promise for chemical happiness. Further investigation showed that ill effects of tryptophan were actua........ Read more »

On seasonal allergies and IBS
by Aurametrix team in Irritable Bowel Blog
Irritable Bowel Syndrome is nothing to sneeze at. Especially during the sneezing season. As a matter of fact, you are more prone to have irritable bowel if you have a seasonal allergy. The likelihood of IBS is 3 times higher in patients reporting atopic symptoms (2.67 times higher in patients with seasonal allergic rhinitis and 3. 85 times higher in patients with allergic eczema, according to Tobin and his colleagues who administered questionnaires to 125 patients). So some of that abd........ Read more »

Hold the Starch?
by Aurametrix team in Irritable Bowel Blog
Starch is that stuff that stiffens your shirts. It's also what most people eat for fuel. Wheat, rice, corn, oats, potatoes are all very starchy foods. Many popular diet plans call starch a second-rate food that should be avoided at all costs. No-starch and low starch diets are favored by irritable bowel communities, while former Weight Watchers, Jenny Craig and Atkins enthusiasts love the new Carb Lovers Diet praising starch. Yet, there may be something good about starch even for those with........ Read more »

Much ado about Bowel Movement
by Aurametrix team in Irritable Bowel Blog
Want to manage your toilet metrics? There's an app for that. Actually, multiple apps - like this one recording precise GPS location of bowel events along with their shapes and odors or IBS symptom tracker and GI monitor, approved and designed by gastroenterologists. Yet, the lists of metrics provided by these applications are not complete - no options to record color, consistency, texture, effort... And what about total time spent? According to IBS forums, it could range from seconds to ... "lon........ Read more »

Adding red to your diet

Finding the Goldilocks Solution
by Aurametrix team in Irritable Bowel Blog
A top story in today’s news is related to a recent scientific paper published in Current Biology concerning the dinosaurs. British scientists wanted to know, Could methane produced by sauropod dinosaurs have helped drive Mesozoic climate warmth? By their estimates, some 520 million tons of methane (a “greenhouse gas” emission) were produced by the flatulent beasts every year. This begs the question, do flatulent humans today also contribute to global warming? Probably........ Read more »

Carbohydrates for your bacteria
by Aurametrix team in Irritable Bowel Blog
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........ Read more »

Molehills and Mountains
by Aurametrix team in Irritable Bowel Blog
If you suffer from IBS, chances are you're very considerate of others and even possibly an anxious 'catastrophizer'. It was repeatedly concluded based on magnetic resonance imaging of the brain and psychological questionnaires - for students, older men and women, Easterners and Westerners, right-handed and left-handed individuals. In fact, IBS sufferers' anxieties are somewhere in between those of people with Crohn's disease (similar to healthy persons) and panic patients. And many IBS suffere........ Read more »

Coffee: Bugs and Debugging
by Aurametrix team in Irritable Bowel Blog
Coffee can bug or de-bug you - in many different ways.It can actually energize your gut bugs. Nestlé 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. Bifidobacteria has been long suggested to be therapeutic for the relief of intestinal disorders, including Irritable Bowel Syndrome ........ Read more »
