How to Reduce Radiation with Spirulina

What gets your vote for the healthiest food in the world? 

Well, the AARP came up with a list, and their number one food to extend your life is actually a bacteria.  It’s the same bacteria that NASA gives the astronauts on space missions.  And no, it’s not Tang.   

How does this bacteria rank as the number one food?  One reason is that it’s been proven to protect us against the harmful effects of radiation.

Now, even if you don’t lose sleep worrying about the next Fukushima nuclear disaster, you’re still living in a radioactive world.  We’re bombarded by radiation from:

  • Medical tests like X-rays, mammograms and CT scans…
  • Airport security scanners…  
  • Radon gas in basements, and
  • Residual radiation in our atmosphere from nuclear accidents around the world.

All of that accumulated radiation is hazardous to your health.  But this one food can help keep you safe from harm.

That “superfood” is spirulina.  You may hear it called blue-green “algae,” but spirulina is technically a single-celled cyanobacteria which, like algae, contains chlorophyll and gets its energy from photosynthesis. This article will show you how to reduce radiation with spirulina. 

You’ve probably seen spirulina growing on hot days in fresh water pools.  But here’s how this pond scum can help save your life.

Spirulina Saves Children after the Chernobyl Nuclear Disaster

In 1986 Chernobyl’s nuclear plant went into meltdown, leaving four million people living on 11,000 square miles of radioactive land.  For decades, residents of the Ukraine and Belarus lived with daily radioactive contamination of their air, water and food. 

More than 160,000 children suffered with radiation poisoning leading to leukemia, cancer, thyroid disease, anemia and blindness. 

At the Belarus Institute of Radiation Medicine, doctors started giving five grams of spirulina to the sickened children every day.  After just 20 days, the spirulina reduced the radiation levels measured in their urine by 50%.  In addition, the children showed rapid regeneration of their bone marrow, spinal fluid, blood cells and livers. 

That experience spurred additional spirulina studies.  In 2000, Ukrainian researchers gave rats a lethal dose of radiation.  The rats were expected to die within 14 days but spirulina helped reverse the effects of the radiation and extend their lives.   

Shortly after that, a Chinese study found that spirulina increased the number of white and red blood cells, and bone marrow cells in animals exposed to radiation. 

The researchers concluded that spirulina effectively protects against the damage caused by both chemotherapy and radiation and could be an adjunct to cancer therapy.

Researchers believe that spirulina’s powers come from phycocyanin, the blue pigment that gives spirulina its unique color.  Phycocyanin stores nitrogen atoms which bond with heavy metals and radioactive substances.  Once the nitrogen grabs the radioactive material, the spirulina drags it safely from the body. 

How to Get This Superfood in Your Diet Today

If you go through airport security, fly on a plane or get dental X-rays, CT scans or mammograms, you may want to think about building up your defenses to radiation by making spirulina a daily habit. 

Besides protecting you against radiation, spirulina also provides more than 100 nutrients, which makes it the most complete food on earth.  The ancient Mayans and Aztecs relied on it for their protein because spirulina has a higher percentage of protein (70%) than any other food. 

And it contains all of the essential amino acids, making spirulina great for building bones, muscle, strength and endurance.

You can find spirulina in your local health food store in capsules or in chewable tablets.  The recommended dose is 3,000 mg per day for adults and 500 to 1,500 per day for children. 

Spirulina also comes in powdered form.  You can add one teaspoon to orange juice or apple cider, or just plain water.  Its unique vibrant blue overwhelms anything you add spirulina to, but don’t be put off by the color.  Try adding it to green smoothies or guacamole where the color isn’t as noticeable.

Some people sense a slight fishy taste from spirulina but that can be easily masked by adding it to smoothies or juices.  Experiment with different brands to find the best taste for you.     

I use Hawaiian Spirulina Pacifica® powder which is very mild and pure, with no fishy taste.  It’s grown in 90 square acres of pristine waters in Hawaii, free of pesticides and GMOs.
