These days more and more patients are asking me about cannabidiol (CBD oil).

And today I can tell them something I couldn’t a month ago: Hemp-derived CBD oil is now legal in all 50 states!

You can legally buy it. You can legally use it. And no prescription is required. Continue reading

I Eat These Like M&Ms

By David Blyweiss, M.D., Advanced Natural Wellness

January 16, 2019

Fresh organic blueberries are, by far, one of my favorite snacks.

Most of the time I eat them the same way people eat M&Ms. I just toss a small handful into my mouth, then savor the sweet burst of flavor that explodes when I bite into them.

Some of my patients have noticed this strange little “addiction” of mine. One of my long-time patients even teases me about it… she calls me Dr. Blue-weiss instead of Dr. Blyweiss.

Well I’ll be honest with you. The taste alone is enough to have me hooked on these tiny berries. I might even eat them if they were bad for me.

But they aren’t! Continue reading

Why So Many People are Dying of Embarrassment

By David Blyweiss, M.D., Advanced Natural Wellness

January 11, 2019

Every now and then I meet with a shame-faced patient.

It’s not because they did anything wrong. They just feel like they did something stupid.

I’m talking about R.B, whose daughter rushed her to the emergency room in the middle of the night because she was having chest pains. It turned out to be nothing more than a bad case of heartburn. (They call it heartburn for a reason!)

I’m also talking about J.T. – a big man who experienced severe stomach cramps, excruciating back pain and nausea in the wee hours of the morning. He thought it was food poisoning or a ruptured appendix. Continue reading

Busting Through the Carbohydrate Myth

By David Blyweiss, M.D., Advanced Natural Wellness

January 7, 2019

In the January 2nd issue of Advanced Natural Wellness we took the first step in addressing the age old diet question: Is a low-fat or low-carb diet the best for weight-loss and health?

And the answer is pretty simple.

When you eat the right kind of fats and carbohydrates, you don’t need to cut either of them from your diet.

And believe me! Cutting out fats and replacing them with the wrong kind of carbs can be deadly. Continue reading

Age-Old Question: Low Fat or Low Carb?

By David Blyweiss, M.D., Advanced Natural Wellness

January 2, 2019

You’ve heard that a high-fat/low carb-diet is bad for you… that eating this way will make you fat and give you heart disease.

You’ve also heard that eating a high-carb/low-fat diet is bad for you… that it messes with your metabolism, encourages weight gain and leads to diabetes.

With mixed news like this, what the heck are you supposed to eat? (And seriously, when did eating a healthy diet get so complicated?)

Actually, it’s not nearly as difficult as you might think. Continue reading

6 Ways to Banish Fatigue in 2019

By David Blyweiss, M.D., Advanced Natural Wellness

December 31, 2018

Over the past several weeks I’ve noticed more and more of my patients have succumbed to holiday fatigue.

Their nerves are frazzled. They’re stressed out, run-down and ready to hibernate for the next month or two.

If you feel the same, you can blame it on the relentless pressure you’ve been under for the past four to six weeks – perhaps even longer.

You know the deal. Continue reading

Stop Eating Dead Pickles

By David Blyweiss, M.D., Advanced Natural Wellness

December 28, 2018

Although I often recommend that patients take a probiotic supplement, there is nothing better for your gut health than eating fermented foods.

These foods contain probiotics that support a healthy gut, boost the nutritional value of foods and help you absorb those nutrients better.

Eating fermented foods on a regular basis supports immune response, weight management, cardiovascular health, glucose and insulin metabolism, boosts mood and can even help reduce muscle soreness after workouts. Continue reading

Eat This Fish Not That One

By David Blyweiss, M.D., Advanced Natural Wellness

December 26, 2018

Every now and then I run across a patient who won’t eat fish. It’s not because they don’t like it. It’s because they’ve read one too many scary stories about mercury poisoning.

I get it. And I agree that all heavy metals, not just mercury, are a problem in today’s society.

However, this may be one instance where avoiding a specific food group for “health reasons” may actually be doing more harm than good.

Seafood is one of your best sources of fats, protein, vitamins, and minerals that promote good health. Regular fish consumption can… Continue reading

Weird Signs of Heart Disease

By David Blyweiss, M.D., Advanced Natural Wellness

December 19, 2018

My patients are a curious group. They bring me all kinds of weird health tidbits they find online.

“Is this really true?” asks one patient.

“I’ll bet this is just a bunch of baloney,” says another.

Most of the time, they’re right to question what they’ve found. But every now and then, one of those “too weird to be true” concepts actually has merit. Continue reading

Why Airplanes Make You Sick

By David Blyweiss, M.D., Advanced Natural Wellness

December 17, 2018

Several weeks ago I met with a patient who recently arrived home after a 14 hour flight.

The poor guy was miserable. His skin was bad. He was dehydrated, constipated, bloated, fatigued and suffering severe muscle spasms.

His immediate thought was that he had contracted some sort of deadly disease during his overseas travels. But it was much simpler than that.

  • After sitting for hours on end at high flight elevations, excess fluid had become trapped in his body tissue.
  • He didn’t want to keep getting up to urinate on the flight. So he limited his beverage intake and ended up dehydrated.
  • Gassiness was a big concern. His intestines felt like they wanted to explode.
  • When his flight landed he was in a rush. This big fellow exerted himself by jogging through the hot, humid South Florida airport parking lot to get to his next appointment – pulling his heavy luggage closely behind.

All of this created the perfect storm for a somewhat rare case of rhabdomyolsis – a catastrophic condition where muscle fibers breakdown and leak damaging proteins into the bloodstream.

When these proteins are shuttled into the kidneys it shuts them down.

After a few touch-and-go moments, we rehydrated him and got his electrolytes back in order. Then, I placed him on a few supplements and an 85% plant-based diet geared to increase his circulation and improve kidney function.

I’ve been working with this man for awhile now and stopped by his house to see him the other night.

I couldn’t be happier with the results. His energy levels are back to normal. Muscle function is restored. He even lost a few pounds during the process.

While this is an extreme case of flight syndrome, it’s also a cautionary tale that anyone who “flies the friendly skies” should take to heart.

Being trapped on an airplane for hours on end is nothing like sitting at your desk.

First of all, you’re flying in a cabin filled with compressed air. It literally sucks the moisture and much-needed electrolytes out of your body. (High altitude makes matters even worse. At 30,000 feet, you lose somewhere around a pint of water from your body every 30 to 60 minutes.)

Second, remember that when you fly you’re sitting in a huge tub of germs. It’s like being trapped in a petri dish, but worse. When you lose moisture in your eyes, nose, mouth and skin, you develop micro-breaks in the tissue. This makes it extremely easy for bacteria and viruses to set up house in your body.

Third, aircraft cabins are generally set at about 75% of atmospheric pressure. This lowers the oxygen levels in your blood and can make you feel tired, off-balance and headachy.

Fourth, as the air pressure in the cabin drops it causes the gasses in your body to expand. This leads to bloating, constipation and gassiness. At the same time, sitting for a long period time can cause blood to pool in your legs and feet. So it’s not uncommon to get off of a plane feeling more like a beach-ball than a human being.

It’s no wonder so many people feel weak, achy and exhausted for weeks after flying… or why so many end up suffering a flight-acquired cold or flu for the next seven to 14 days. Or longer.

How to Stay Healthy on Your Holiday Flight

Give your immune response a big boost. One of the first things I do in the days before flying is to load up on vitamin C. At high enough levels, it can boost immune response and fight off bacteria and viruses that run rampant in airplane cabins.

recommend 2 grams daily in divided doses. I also boost with 2 grams just before or after getting on the plane as a short term antiviral. Emergen-C packets are my favorite; they go in the water you have to drink anyway…. you know, two birds one stone.

Avoid moisture-sapping foods. Stay away from alcohol, caffeinated beverages and salty foods prior to and during your flight. These all act as diuretics and dehydrate you even further. (Plus, keep in mind drinking alcohol suppresses oxygen absorption, which is already a concern when flying.)

Prevent in-flight gassiness and bloating. Carbonated beverages, beans, cruciferous veggies and dairy are all “gassy” foods. If you eat them pre-flight, it can increase bloating during your flight. So it’s a good idea to pass up on these in the 24 hours before you hit the skies.

Walk, walk and walk some more. Airline attendants like to keep you tethered to your seat so they know exactly where everyone is and what they are doing. Buck the system! Take a walk up and down the aisle every 30 minutes or so. It will help keep blood from collecting in your lower extremities.

Stay hydrated. Don’t count on in-flight services to come around often enough to support your water intake. Depending on the amount of time you expect to spend in the air, purchase one or two liters of water after passing security and drink about eight ounces every 30-60 minutes. (If you have to pee more than the other passengers, so be it…you have to get up and walk anyway. You’ll come home all the healthier for it!)

Go for the healthy snacks. Pass up on the chips, peanuts and other moisture-robbing food options that may be offered on your flight. Instead, choose the fruit or veggie option. Better yet, pick up a nice fruit salad or veggie wrap just before boarding.

A nasal spray with saline (I like the Ocean brand )  and natural tears eye drops will offer further protection to keep your most vulnerable mucous membranes moist and actively protecting you.

Every little bit of fortification can help keep you safe, healthy and happy on your holiday journeys.
