Pocket?sized gadget identifies your problem foods 能識別問題食物的袖珍裝置

據(jù)估計(jì)，全世界有十分之一的人患有與消化系統(tǒng)相關(guān)的疾病。然而，發(fā)現(xiàn)哪些食物會引起不良反應(yīng)是一個(gè)漫長而艱苦的過程，而且代價(jià)昂貴。為了解決這一問題，愛爾蘭工程師安格斯·肖特和彼得·哈特發(fā)明了只有5平方厘米大小的便攜式設(shè)備來測量一個(gè)人呼出的氣體中的氫含量，以幫助使用者監(jiān)測消化系統(tǒng)疾病。

1It is estimated that one in ten people worldwide are suffering from diseases that are

related to digestive conditions. There is no cure， although it can be managed with lifestyle and dietary changes. However， discovering which foods cause a bad reaction for individuals can be a long and painstaking process and its expensive as well.

2Thats why Irish engineers Aonghus Shortt and Peter Harte founded FoodMarble， a startup that has invented portable devices， measuring just 5 square centimeters. It can be used to test the hydrogen levels in a persons breath， which is a key signal for digestive disorders.

3FoodMarbles app has a database of nearly 1，000 foods， which are typically hard to digest. FoodMarbles AIRE device， which was launched in 2018， allows users to test for hydrogen after meals， giving them real?time feedback on what food is bad for their body. Readings are transmitted via Bluetooth to the FoodMarble app， where users can record what they eat， and over a course of weeks spot the ingredients that cause symptoms.

4Hydrogen breath tests have long been a method for diagnosing digestive conditions， but the technology has not been widely accessible because it requires multiple trips to the hospital for testing. By miniaturizing it， the technology can be accessible to ordinary people. So far， FoodMarble has sold 25，000 of its breath sensor devices， which have out?

performed other hydrogen breath test methods.

5Doing breath tests in a clinical setting can be challenging and needs more manpower， requiring a medical assistant to take a breath sample every 15 minutes over a number of hours. The attraction of the FoodMarble device is that its not just a one?time analysis of the breath. A person could use it multiple times to gather multiple data points on which to make better judgment calls and assessments about food sensitivities.

6Dr Tara Troy， a gastroenterologist （胃腸病學(xué)家）， warns that hydrogen breath tests are not a foolproof method for diagnosing digestive problems and can sometimes produce false negatives and positives. “It is important to complement them with other tests that can determine if a patient is suffering from more serious conditions. Anyhow， they are hugely valuable in offering some sort of objective criteria for patients with digestive conditions，” said Troy.

Thats why Irish engineers Aonghus Shortt and Peter Harte founded FoodMarble， a startup that has invented portable devices， measuring just 5 square centimeters. 這就是愛爾蘭工程師安格斯·肖特和彼得·哈特創(chuàng)立FoodMarble的原因。FoodMarble是一家初創(chuàng)公司，發(fā)明了只有5平方厘米大小的便攜式設(shè)備。

【點(diǎn)石成金】本句中，why引導(dǎo)表語從句，measuring just 5 square centimeters為非謂語動詞作定語。
