Orange juice is full of vitamin C which supports the immune system by increasing production of white blood cells that are on the front lines. But there’s more going on behind the scenes. Along with other nutrients, new research shows this old-fashioned remedy gets to the core of what leaves your body defenseless in the face of infection.

Aging is due in part to varying rates of immune system decline that trigger chronic inflammation. People with healthy immune systems are able to fight off this inflammation to some extent, but those whose aren’t as strong will age faster and be more prone to frailty and disease. Since inflammation is treatable, all we’ve needed was a way to measure it.

Imagine being in pain all over your body, feeling crushingly tired and weak, and being so foggy-brained that you can hardly accomplish simple, everyday tasks. Now imagine years of being misdiagnosed or told “it’s all in your head.” That’s been life for people with fibromyalgia, until now…

As you already know, COVID-19’s symptoms weren’t just upper respiratory. It’s been reported that many people with the virus experienced GI problems, too. It may seem random, but the connection with viral infection is much more concerning: A condition that can act as an open door to disease…

Catching a cold is a drag and little is worse than a sore throat. But if you turn to drugstore cold remedies to ease the discomfort, think twice. They not only do little good, but they also harm upper respiratory cells…

Dyes used in food are supposed to be safe for you to eat, but we’ve already seen evidence that’s not the case. Artificial food colorants have been linked with everything from hyperactivity in children, allergic reactions and worse — and now, there’s evidence they may impact your gastrointestinal health as well…

As they say, prevention is the best medicine. And one of the most promising ways to avoid illness is to shore up your immune system by promoting a healthy and balanced gut microbiome.

King Tut, Cleopatra, and Hippocrates relied on black cumin seed for an array of conditions, including malaise, weakness, coughing and skincare. When something is carried down over the years as a “remedy,” especially as long as black cumin seed, there’s got to be something to it. But when the research agrees, it’s even better.

Although it may seem like exercising would be a difficult task for anyone undergoing treatment for breast cancer, according to doctors at Johns Hopkins, it’s one of the best things to do. Not only does it lessen the side effects of treatment, research shows it has a direct impact on treatment outcomes.

Fructose has been a common food additive for decades, and its overconsumption is known to cause issues with the liver and insulin resistance, a precursor to obesity and diabetes. What hasn’t been as clear is how fructose impacts the immune system, and that’s a gamble with high stakes right now.

Antibiotics are lifesavers. But because we’ve relied on them too heavily, we’ve contributed to a big downside: antibiotic resistance. But scientists are finding promise in a nutrient found in many common foods that may trigger good bacteria in the body to go after disease-causing pathogens.

The difference between a mild case of the flu and possible hospitalization is the development of pneumonia. Just in time, researchers have identified one more way to reduce risk for a lung infection…
