How long will coronavirus vaccines protect people?

Ian Haydon helped test Moderna's coronavirus vaccine last year. Now, he's helping test the tweaked version of that vaccine designed to fight a new, more contagious variant.

"A year ago, I tried the Moderna vaccine to see if it was safe. (Spoiler: It is!) Now, on my #COVIDvaccine anniversary, I'm happy to share that I just got a 3rd dose. This booster experiment will reveal if strain-adapted vaccines boost immunity & whether they are safe," Haydon, a communications specialist at the University of Washington, said via Twitter last Saturday.

"It's unclear whether this new tweaked version is even going to be necessary," Haydon told CNN in a telephone interview.
"But it's being developed and tested now so that we have it in hand."

Magnesium: Basics, Benefits, and Sources

What Is Magnesium?

Magnesium is a critical mineral that the body uses for hundreds of important body processes. It is necessary for more than 300 biochemical reactions in the body. Along with calcium, we need magnesium for the proper function of muscles and nerves. Sufficient levels of magnesium are necessary to maintain a healthy heart, bones, and to regulate blood sugar and blood pressure levels. Your body needs magnesium to generate energy. The mineral is present in a variety of foods and beverages, but many people may still fall short of optimum levels. In these cases, your doctor may recommend that you take magnesium supplements.

High-fiber diet may play a role in controlling the inflammation associated with COVID-19

A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines. However, while in vitro treatment of cells with these molecules did not significantly influence local tissue infection, it reduced the expression of a gene that plays a key role in viral cell entry and a cytokine receptor that favors inflammation.

An article reporting the findings is published in the journal Gut Microbes.

Eye Health: Foods, Vitamins and Nutrients to Improve Eyesight

Just like every other part of the body, eyes age and do not work as well as we get older. Poor diet, excess sun exposure, toxins, infections, and physical and emotional stressors cause wear and tear on the body, including our eyes. This wear and tear produces free radicals, unstable molecules that harm us at the cellular level. The eyes are prone to damage by free radicals. This damage may result in you having vision problems or suffering from age-related macular degeneration or other eye disorders, but you can help protect your eyes by making healthy food choices.

Antioxidants like vitamin C, vitamin E, vitamin A, beta-carotene, zinc, lutein, zeaxanthin, and omega-3 fatty acids protect against free radical damage that can harm your eyes. You can find these nutrients by eating colorful fruits and vegetables that will protect your eyes and boost your overall health. We’ll take a look at these on the following slides.

More Around the Middle

Belly fat is a problem, and not just because of how it looks. The type of fat that collects in your belly is called visceral fat.
