Many people believe that drinking grape juice prevents stomach flu. However, reports of this are anecdotal and there is no scientific evidence to support this belief.
Stomach flu is a broad term covering different infections that cause vomiting, abdominal cramps, and diarrhea.
In this article, we will explore why people think grape juice may help prevent stomach flu and what scientists know about the health benefits of grape juice. We will also detail the scientifically recommended ways of preventing stomach viruses.
Some people believe that drinking grape juice protects them against stomach viruses.
Popular theories argue that the drink alters the pH of the stomach and that the increased acidity stops the virus from multiplying.
Others suggest that the juice has antiviral properties. But scientists have yet to prove a link between grape juice consumption and stomach flu prevention.
The origins of these beliefs may lie in what scientists know about grapes.
A study published in the journal Nutrients suggests that taking a grape powder supplement can increase gut microbiome diversity, which may promote good health. The powder contains the equivalent of two servings of grapes or around 100 milliliters of grape juice.
An article published in the American Society for Microbiology’s ASM Journals looks into how differences in people’s gut microbiomes could influence the severity of symptoms for people with norovirus infections. The article states that the microbiome could help explain why some people can resist the infection and others are asymptomatic.
However, the authors recognize that their study is the first to collect data on the composition of gut microbiomes and norovirus infections and that they need to conduct further research. They also note that this was a small study, covering just one strain of norovirus.
Additionally, an article published in the
A 2015 study published in the journal Food Control reports that resveratrol may interfere with the early stages of norovirus infection. However, this study used surrogate noroviruses that affect cats and mice.
Scientists are calling for further studies to see if there is a link between grape juice and stomach flu.
Adopting a healthy lifestyle, taking plenty of exercise, and eating healthy food can help boost a person’s immune system and may help them fight off infections.
According to a 2020 report by the Produce for Better Health Foundation, people are eating fruit and vegetables less often than they used to. It notes that there has been a 15% reduction in fruit juice consumption since 2004.
People can drink grape juice as part of a healthy diet. The
Preventing stomach flu from spreading
Stomach flu, or viral gastroenteritis, is a highly contagious illness that spreads easily.
It advocates sticking to a proper hand hygiene regime at all times. This includes washing the hands regularly with soap and water and being extra careful after using the toilet or changing a diaper, before preparing food or eating, and before taking any medication.
People should wash all fruit and vegetables before preparing them and make sure to cook all shellfish properly. The
If someone has stomach flu and is experiencing sickness and diarrhea, the CDC suggests a thorough cleanup immediately. Wipe the entire area with a bleach-based cleaner and leave it for at least 5 minutes. Then wash with soap and hot water.
People need to regularly wash any
If a person with stomach flu can drink grape juice, this can provide a useful boost of vitamins and minerals along with the liquid. Diluting the juice with water may make it more palatable.
According to the CDC, most people with stomach flu get better within
There is no scientific link between drinking grape juice and preventing stomach flu and stomach viruses.
However, grape juice does contain many compounds that may improve the diversity of the gut microbiomes, help heart health, and prevent some illnesses associated with aging.
