Fight COVID with this island favorite

As I’ve written here before, everyone’s COVID story is going to be different.  

And that’s especially true for those of us with regular access to testing, vaccination, anti-viral medication, monoclonal antibody treatment, hospitals, and additional resources.  

But for some folks, those options simply don’t exist. 

That’s why I’m so excited to report on a new study that focuses on a powerful plant extract that could help in the fight against the coronavirus. Not some fancy, overly expensive drug. 

In fact, this study looked at form of SEAWEED that’s a diet staple in places like Japan, New Zealand, and Hawaii. 

The best part? Lab experiments suggest that ulvan—a seaweed extract—may help STOP the virus in its tracks. 

Seaweed extract shows promise against COVID 

In a lab setting, a team of scientists exposed cells in test tubes to both ulvan and COVID-19. And they found that when cells were exposed to ulvan, they didn’t get infected with the coronavirus.  

These results were published in the journal PeerJ. And I have to say, they’re quite promising. Because they suggest that a simple plant extract might help prevent COVID infection in people who can’t easily afford—or access—other treatments. 

Of course, only time will tell if this study will be repeated and, eventually, shown to be effective in human trials. But I won’t hold my breath. (Far too often, promising, early-stage research gets squashed so Big Pharma can gain an even bigger piece of the healthcare pie.)   

What does this mean for you? 

Well, other forms of edible seaweed have also shown promise against COVID-19 infection… along with other agricultural and human viruses. So, it can’t hurt to add this health-boosting food to your balanced diet.  

Enjoy the health benefits of seaweed 

Seaweed contains various vitamins and minerals—like potassium, iron, magnesium, calcium, and iodine. It’s also high in antioxidants and phytochemicals—which help boost immunity. Plus, it’s a good source of protein and has been shown to help reduce inflammation—the No. 1 cause of disease and aging. And it’s high in serine, an important amino acid. 

In other words, it’s a great addition to your already healthy, balanced diet—and to your immune-boosting protocol.  

You can enjoy seaweed in whole leaf, flake, and powder forms. Then, you can easily incorporate it into various meals. As for me, I love making a simple seaweed salad and pairing it with sashimi, which I may just have to demonstrate in an upcoming episode of Cooking with Dr. Fred (on YouTube and Instagram).
