Travelers’ diarrhea not improved by restricted diet

06.08.2004


Travelers suffering from ’Montezuma’s revenge’ may not necessarily have to avoid tasty cuisine



Travelers suffering from "Montezuma’s revenge" may not necessarily have to avoid tasty cuisine. In a comparison of two groups of patients receiving antibiotics to treat travelers’ diarrhea, those who restricted their diet to broth and bland foods did not recover any faster than those who ate anything they wanted, according to an article in the August 1 issue of Clinical Infectious Diseases, now available online.

Travelers’ diarrhea is usually caused by a bacterial infection from eating contaminated food. Traditionally, patients with cases of travelers’ diarrhea have been advised to restrict their diet to clear liquids and simple carbohydrates, like crackers, toast, Jell-O, rice, bananas and baked chicken, and told to steer clear of dairy products and spicy or fatty foods.


However, research on diet in relation to recovery from travelers’ diarrhea was lacking, so University of Texas researchers compared two groups of 105 college students visiting Guadalajara, Mexico. The subjects in each group were receiving antibiotic treatment for diarrhea. One group was told to stick to the bland diet, and the other was given no restriction on what to eat, although both groups were advised to drink plenty of fluids to prevent dehydration. The results showed no real benefit to the diet restriction.

One reason for the two groups’ equally speedy recovery time was probably their general good health, said study co-author Dr. Herbert DuPont, a professor at the University of Texas Houston Health Science Center. "Travelers are a different group than children with cholera or people with viral gastroenteritis," said Dr. DuPont, because they tend to be "young, healthy people with relatively normal intestinal physiology."

Despite the similarity in the patients’ recovery time, the bland diet recommendation might still be advisable for some, especially if they did not take antibiotics to treat the diarrhea, according to Dr. Charles Ericsson, lead author of the study and Head of Clinical Infectious Diseases at University of Texas Houston Medical School. "The thought is that simple carbohydrates are easier to absorb during diarrhea and would be less likely to contribute to osmotic load and worsen diarrhea, and such a diet might speed the repair of the gut and avoid persistent symptoms," Dr. Ericsson said. "The problem is that we do not know yet how to identify who might benefit from such a diet."

The best way to cure travelers’ diarrhea is to seek antibiotic treatment, said Dr. DuPont, and to keep eating so that the diarrhea bout isn’t prolonged. "The intestinal tract has been injured," he said. "It needs to grow back and needs to be provided with calories." Dr. Ericsson agreed. "The contamination in food is like rolling dice. It is more important to accept some risk of diarrhea rather than starve," he said.

To avoid getting travelers’ diarrhea in the first place, Dr. DuPont recommends food that is dry (bread or toast), is very high in sugar (syrup or honey), is highly acidic (citrus), is able to be peeled (fruit), or is freshly cooked. "Tell the waiter that you’re going to require everything served steaming hot," said Dr. DuPont.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
