This One Supplement Reduces Your Severe Flu Risk by 90 Percent, Study Says
This isn't the first study to link a diet high in omega-3s with health benefits. A study published in BMJ in 2018 followed 2,622 adults with an average age of 74 from 1992 and 2015 to see if they developed any chronic diseases or other mental or physical ailments.
The researchers also pointed out that omega-3s can still have important health benefits. But while the convenience of taking a daily supplement may be enticing, you're more likely to receive the actual health benefits from eating a diet of omega-3 rich foods, especially fatty fish such as mackerel or salmon.
"Based on these and other findings, we can still tell our patients to eat Omega-3 rich foods, but we should not be recommending them in pill form as supplements or even as combined (EPA + DHA) prescription products," he said. "Our data adds further strength to the findings of the recent REDUCE-IT (2018) study that EPA-only prescription products reduce heart disease events."
The researchers, who will present the study at the 2021 American College of Cardiology's Scientific Session, conclude that the convenience of omega-3 supplements in pill form might be creating a self-canceling effect when it comes to heart health.
A team of researchers at the Intermountain Healthcare Heart Institute in Salt Lake City analyzed 987 patients in their database who underwent their first angiographic study between 1994 and 2012. Blood samples from the patients allowed the scientists to monitor levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are often found in omega-3 supplements. According to a release from the study's authors, the team then tracked them over a period of 10 years to look for any major heart health events, including heart attack, stroke, or heart failure, that led to hospitalization or death.
Dietary supplements are a daily ritual for many looking to make sure they get all of their required nutrients. Some of the most commonly taken pills have been found to have some seriously positive effects on overall brain and heart health, especially as we age. But a new study has found that one popular supplement, in particular, might be putting your heart at risk. Read on to see why you might want to change up your regimen.
Despite the results, the researchers were also quick to point out that even small doses of zinc can cause non-serious side effects such as nausea—and especially in the case of nasal sprays, temporary loss of smell. But the data also leaves it unclear exactly which method and which dosage is best to secure the results seen in the analysis. For now, they suggest more studies are needed on the topic.
Ultimately, the researchers conclude their findings supported the use of zinc as a way to avoid or take care of a cold or a bout with the flu. "The marginal benefits, strain specificity, drug resistance, and potential risks of other over-the-counter and prescription medications makes zinc a viable 'natural' alternative for the self-management of non-specific [respiratory tract infections]," the study authors wrote in a statement. They also added: "[Zinc] also provides clinicians with a management option for patients who are desperate for faster recovery times and might be seeking an unnecessary antibiotic prescription."
Besides being able to stave off the virus potentially, the researchers also found zinc supplements could still hold a benefit for those who were already sick. Results showed that those using a zinc nasal spray or a liquid formula taken under the tongue saw their symptoms dissipate two days earlier on average than patients given a placebo.
The latest insight comes from a meta-analysis published this month in the journal BMJ Open. In total, researchers reviewed 28 clinical trials that included 5,446 adults at risk for or infected by a viral respiratory tract infection such as the common cold or the flu. While none of the studies specifically focused on the use of zinc to prevent or shorten the length of illness, the data within included information on zinc dosage, duration of the illness, recovery time, and the severity of symptoms from the virus, Eating Well reports.
After more than a year and a half of living under a global pandemic, the idea of catching the flu almost feels like a distant memory. But even as life slowly begins to return to normal, the truth is that becoming infected with influenza can still be a harrowing experience. While each year changes in severity, the 2018 to 2019 flu season saw an estimated 29 million illnesses, 13 million flu-related medical visits, 380,000 flu-related hospitalizations, and 28,000 flu deaths, according to the data from the U.S. Centers for Disease Control and Prevention (CDC). As always, doctors are urging the public to get their flu shots to help shore up their immunity—especially amid concerns the flu virus could come roaring back after flu cases were tamped down by COVID-19 preventions last winter. But according to new research, there's one supplement that can help cut your risk of developing severe flu symptoms. Read on to see what you should be taking to give your body another line of defense.
