Immunity

A healthy immune system fights off assaults to your body from a wide range of enemies, including everything from virus and bacteria to cancer. These articles will give you insight into how you can boost your immune system and help fight off illness.

Zika Virus: A threat but not for U.S.

First, the good news for most Americans and most of my readers. The mosquito-borne Zika virus is unlikely to threaten your health. Yes, when the World Health Organization (WHO) proclaims Zika “a public health emergency of international concern,” that’s scary. But the scariest coverage has been from authorities with global responsibilities, like WHO and our […]

Antibiotics alternatives for cold and flu

I like the way one writer puts it: “For the love of God, people, stop taking antibiotics for colds.” I’ll add, with equal passion: Fellow physicians, stop prescribing antibiotics for colds! And, cold and flu sufferers, stop asking your doctor for antibiotics. Antibiotics are among the most over-prescribed medications we’ve got. Yet they should be […]

Asthma and the Hygiene Hypothesis

Quick—what’s the first thing you think of when I say “bacteria?” If it’s, “Bacteria, ick! Must wash hands,” you would be wrong on two counts: While some bacteria are indeed icky, even dangerous, our health is hugely dependent on “good,” or “friendly” bacteria, called probiotics, that live in our gut, or biome. Recent research is […]

Antibiotic use increases diabetes risk

How many times do I have to wave this flag? Antibiotics can be hazardous to your health. Researchers in Denmark have just shined new light on this warning—by finding a link between antibiotics use and the risk of developing Type 2 diabetes. I’ve been saying forever that antibiotics wreak havoc in your gut, wiping out […]

5 Flu Prevention Plans

It’s official. As leaves turn orange, decorations get spooky, and the calendar flips to fall, my mind goes to a different dawning season. Flu season. Too many people don’t give the flu the respect it deserves. Which is scary, since we don’t have very good treatment options. The flu vaccine is a best-guess half-measure, leaving […]

Shingles Prevention and Treatment

Recently, I’ve had a lot of patients ask me about shingles. I blame Big Pharma. It’s impossible to watch TV these days without seeing some scare-tactic ad about the pain and danger of shingles. Which is always a lead-up to recommending the new shingles vaccine. The usefulness of that vaccine is up for debate, as […]

Multiple Sclerosis Symptoms and Prevention

Multiple sclerosis (MS) was long considered a progressive autoimmune disorder. This happens when our immune system, designed to fend off viruses, bad bacteria, and other threats, mistakenly attacks normal, healthy tissue. In the case of MS, the body attacks and destroys the protective covering around your nerve cells. It’s like removing the plastic coating of […]

Avian Flu: What’s It All About?

Here’s a scary name from the past that’s back in town again. Highly pathogenic avian influenza. Also known as bird flu, it’s back with a vengeance. As of June, 2015, some 46.8 million birds have been affected on 228 premises in 21 states. The outbreak is called “unprecedented” and the numbers are growing. But don’t […]

Healthy Microbiome Protects Against Deadly Disease

The virus you’ll want to catch When listening to the mainstream medical world, it probably sounds like everything microbial is out to get us. Our soaps come with “antibacterial” and “antimicrobial” stickers colorfully blazing away. More than one diet aims to flush out our systems, ridding us of outside invaders. And there are few words […]

I love the summer. It’s a great time to get outside, enjoy the fresh air, the renewed life, the pleasant temperatures. However, for many of us, summertime also comes with an unwanted guest. Mosquitoes. Mosquitoes aren’t just annoying—they’re dangerous. They carry all sorts of diseases, from malaria to West Nile to, recently, chikungunya. Chikungunya causes […]
