What I’m Doing to Avoid the Swine Flu

Dear Friend,

Dr. Stephen Sinatra

For years we’ve worried about the possibility of a flu pandemic, and it seems those fears may become a reality. The swine flu, which recently surfaced in Mexico, has sickened thousands and alarmed millions of people around the world.

As of the time that I’m writing this, there are 109 confirmed cases of H1N1 flu in the United States—spread out among 11 different states. Not surprisingly, I’ve been fielding a lot of questions about it from colleagues, patients, and subscribers who want to know what they can do to avoid contracting the virus—as well as how to cope if they fall ill. Here’s what I’ve been telling them…

Prevention is your best defense

The first thing you want to do is follow the same basic flu prevention techniques that you would during the regular cold and flu season. So far, the virus seems to be behaving like more common strains of flu, which means good hygiene is essential if you want to avoid infection. Wash your hands frequently and thoroughly, especially if you’ve been around someone who is sick or you’ve visited a public place.

Good hygiene also requires that you avoid touching your eyes, nose, and mouth. This is a special challenge at this time of year because so many of us—including me—have seasonal allergies. However, it’s the best way to avoid transferring traces of the virus that may be on your hands to the mucous membranes where infection could take hold.

Next, eat a consistently nutritious diet. Fruits and vegetables, which are rich in antioxidants, are especially important. You also want to watch your intake of sugars, since high-glycemic carbohydrates and sweets weaken the immune system, as will alcohol.

Bolster your immune system so it’s in peak shape

A strong immune system continues to be your best defense against any acute illness, including the swine flu. There are several potent nutritional supplements that you can start taking now to power up your immune system, including:

  1. Resveratrol: This powerful antioxidant, which is found most abundantly in red grape skins, helps to prevent the flu by making it tougher for flu cells to divide and replicate themselves.

  2. Quercetin: This powerful polyphenol that is found in fruits and vegetables is very similar to resveratrol in its chemical structure. It helps to protect the lung tissues from free radicals, and helps to prevent cytokine storms, which are the inflammatory messengers that can overwhelm healthy lung tissue.

  3. Beta Glucan: This complex sugar (polysaccharide) is derived from the cell wall of baker’s yeast, oats, and barley, as well as some medicinal mushrooms. As a supplement it primes neutrophils, white blood cells in your immune system that engulf alien microorganisms.

  4. Selenium: You need selenium to make glutathione, your body’s most potent natural antioxidant. Plus, as a cardiologist I’m very in touch with the impact of selenium on cardiomyopathy. Years ago, a famous disease in China called Keshan disease was causing cardiomyopathy in adults and children, due to a deficiency in selenium that weakened the heart muscle. When patients were given selenium, it increased the efficacy of the white blood cells, mobilizing them to eradicate the infection that caused the cardiomyopathy.

  5. N-Acetyl-Cysteine (NAC): This important amino acid is the precursor to glutathione—which as I just mentioned is your body’s most potent antioxidant. It also helps to support your liver, and helps remove toxins from your body.

What to do if you begin to feel ill

If you follow all of these precautions and still begin to feel worn down and symptomatic, you want to do three things:

  1. Add licorice root to your supplement regimen. Licorice root extract supports the adrenal glands and fights inflammation in the lungs. Star anise is an herb that is one of the materials used to make the flu medication Tamiflu. Interestingly, the star anise plant is in a similar plant family to licorice root. This may explain the antiviral properties of licorice root extract. There is a lot of press about Tamiflu, but I would be cautious about giving Tamiflu to young adults unless there is a diagnosis of the H1N1 flu, since overuse can cause bizarre psychological reactions. Licorice root extract is safe, and it does have some efficacy in treating viruses. It’s sold in liquid form, and you should take one dropperful under the tongue twice a day. NOTE: If you have high blood pressure, use licorice root extract only on a very short-term basis, one to two weeks at most. With prolonged use, licorice root can cause blood pressure to rise. If you have a home blood pressure monitor, keep a close eye on your readings.

  2. Up your vitamin C intake…and I don’t mean by just a little bit. I recommend 5,000 mg of vitamin C a day, in divided doses, to help fight infection. Just be aware that this much vitamin C can cause diarrhea. If this happens to you, reduce the dosage to the highest amount you can tolerate.

  3. Seek medical help. This is one time that you shouldn’t try to go it alone. The sooner you are evaluated by a doctor, the better your chances of having a short illness and full recovery.

Finally, keep a positive mindset

I can’t stress enough how important it is that you avoid undue stress and have positive intention as we weather this storm. By that, I mean telling yourself that you’re not going to become sick and then trusting that you—and your immune system—are up to the challenge.

Too often, we subconsciously create what we fear the most. This is undoubtedly a frightening time, but don’t allow those emotions to consume you. A cautious but positive approach to life is the best medicine for all of us right now.

It’s also important to remember that we’ve seen swine flu before and it does not carry the mortality and morbidity of other previous flus, such as the epidemic of 1918. The swine flu virus can be checked, and it’s not nearly as horrific as the Asian bird flu virus, which I’ve written about in Heart, Health & Nutrition in the past.

To Your Health,
