Top chlorella brands confirmed to capture dietary mercury, uranium and aluminum:

(NaturalNews) If you take chlorella, I’ve got great news for you today: I’ve just completed research across nearly a dozen chlorella brands and manufacturers, and I’ve conclusively documented the fact that they all bind with and capture dietary mercury with very high efficiency. They also show strong affinity for binding with aluminum and uranium, as is detailed below.

At the same time, chlorella showed little or no ability to bind with lead, cadmium, arsenic and cesium. So it’s very important to understand what chlorella can and cannot do. Many people and product promoters in the natural health industry make the claim that “chlorella removes heavy metals.” This claim is not entirely accurate. As this article (and scientific laboratory results) will show you, chlorella is only good at binding with some heavy metals, but certainly not all of them.

So the claim that “chlorella removes heavy metals” is an example of what I call “fuzzy thinking.” It’s wishy-washy and blurs the details of what’s actually true. If you’re taking chlorella, make sure you understand its strengths and weaknesses! And the good news is that chlorella is fantastic at binding with mercury.

Chlorella exceptionally good at binding with dietary mercury

Every brand of chlorella we tested was able to bind with and capture at least 93% of dietary mercury in our gastric acid digestion simulator at the Natural News Forensic Food Lab. Most brands of chlorella captured mercury at 98% – 99% efficiency.

Here are the results we documented across several brands and manufacturers:

Clean Chlorella: 99%
Dr. Mercola Chlorella: 99%
NOW Foods Chlorella: 99%
Source Naturals Chlorella: 98%
Jarrow Formulas Chlorella: 98%
Sun Chlorella: 98%
Earth Circle Foods Chlorella: 98%
Swanson Chlorella: 93%

Chlorella manufacturers and importers:
RFI chlorella: 97%
Taiwan Chlorella (TCMC): 98%
Febico Chlorella (Taiwan): 98%

Looking at these numbers, you may wonder why Swanson Chlorella is considerably lower at 93%. That’s because Swanson adds calcium to their chlorella, reducing the chlorella concentration in the final product. Their tablets are not actually 100% chlorella.

But overall, every brand of chlorella we tested was very effective at binding with mercury in the human digestion simulator running at our lab.

Arsenic and cadmium capturing capacity is very low for chlorella

My laboratory tests show that Chlorella is not very good at capturing and binding with arsenic or cadmium, two other prominent heavy metals that threaten human health.

My laboratory tests showed that arsenic was only reduced by a maximum of 6% across the different brands of chlorella. Because the range of error in these measurements is closer to plus or minus 10%, these low numbers for arsenic are insignificant.

It seems that chlorella has little or no ability to bind with arsenic. (I have found other natural substances that bind with arsenic, however, and I will reveal those in future articles.)

Chlorella’s binding and capturing potential may be slightly better against cadmium, a toxic heavy metal that contributes to kidney failure. My tests showed cadmium capturing at anywhere from 0% to nearly 9%. But again, as this is all within the range of error, we cannot conclude that chlorella has any validated potential to capture cadmium. (Again, there are other substances which are far better at this.)

Chlorella slightly better at capturing lead, but still not impressive

In my tests, various brands of chlorella were able to capture from a low of about 2% to a high of 17% of lead in our gastric acid digestion simulator.

Although these results are slightly better than arsenic and cadmium, they still aren’t very impressive. (I’ve actually developed a formula that can bind with and capture nearly 100% of lead, and it’s not based on chlorella.)

Because of this, I don’t consider chlorella to be very strong at binding with lead. This means people who have been trying to take chlorella alongside, for example, Traditional Chinese Medicine herbs in the hope of “blocking” the lead aren’t actually achieving the dietary defense they had hoped.

Chlorella extremely good at capturing uranium

The real shocker in all this is that chlorella shows very high affinity for binding with and capturing dietary uranium.

My laboratory tests via ICP-MS show chlorella’s uranium capturing capacity from a low of 88% to a high of 97%.

Uranium, by the way, does not have the same sort of toxic profile as lead, cadmium or mercury. It’s not normally a high priority element to avoid except in the context of nuclear fallout or for people living in regions which have been hit by depleted uranium weapons.

In a fallout scenario, radioactive uranium isotopes can make their way into food, water and air. From there, they can easily poison anyone living in the area. In that context, dietary protection from radioactive uranium isotopes can be extremely valuable, and chlorella may play a significant role in saving lives in such a scenario. But in day-to-day living, uranium isotopes are normally not a significant threat in the food supply.

Chlorella does not bind with cesium-137

In case you were wondering, chlorella has very little ability to bind with radioactive cesium isotopes such as cesium-134 or cesium-137.

As you probably know if you are a regular Natural News reader, I’ve already tested over 1,000 candidate substances for cesium binding potential, and I’ve found a formula that captures radioactive cesium isotopes very effectively. Nearly all substances fail this test, as cesium is a particularly difficult element to capture.

Chlorella’s binding potential with cesium isotopes is also very poor, ranging from 0% to a high of just under 15%, but with the bulk of the results coming in under 4%.

Again, these numbers are not scientifically significant, so we must conclude chlorella has no special ability to bind with cesium isotopes.

Chlorella shows aluminum binding potential

Interestingly, chlorella is one of the very few superfoods that has solid potential to bind with dietary aluminum. This property is quite rare, and most foods actually release aluminum rather than binding with it.

Chlorella happens to demonstrate moderate aluminum binding potential. In my tests, I found chlorella to demonstrate from 12% to 42% reduction in aluminum in a synthetic gastric acid solution subjected to simulated digestion.

This is beyond the range of statistical uncertainty, and results were consistently in the above-30% range for most brands.

What this shows is that chlorella is quite effective at binding with and removing free aluminum during digestion.

Summary of chlorella’s heavy metals capturing potential

BINDING AND CAPTURING POTENTIAL:
Mercury: Very high
Uranium: High
Aluminum: Mediocre
Lead: Low
Cesium: Near-Zero
Cadmium: Near-Zero
Arsenic: Near-Zero

Eating Green Vegetables Improves Your Immune Defenses

New Research Conducted By Immunologists Demonstrates How Eating Green green veggiesVegetables Improves Immune Function.

Be Sure To Include Cruciferous Vegetable-Derived Phyto-Nutrients As Part Of Your Healthy Diet

FACT: Eating Green Vegetables Boosts Your Immune Defenses.

Nutrition researchers have found another good reason to eat green vegetables (from bok choy to broccoli, kale, spinach, etc.); they are the source of a chemical signal that is important to a fully functioning immune system.  The vegetables ensure that immune cells in the gut and the skin known as intra-epithelial lymphocytes (IELs) function properly.

“It is still surprising ” said researchers from The Babraham Institute in Cambridge. “we expected cells at the surface would play some role in the interaction with the outside world, but such a clear cut interaction with the diet was unexpected. After feeding otherwise healthy lab subjects a vegetable-poor diet for two to three weeks, we were amazed to see 70 to 80 percent of these protective cells disappeared.”

Those protective IELs exist as a network beneath the barrier of epithelial cells covering inner and outer body surfaces, where they are important as a first line of defense and in wound repair. The research team now finds that the numbers of IELs depend on levels of a cell-surface protein called the aryl hydrocarbon receptor (AhR), which can be regulated by dietary ingredients found primarily in cruciferous vegetables.

Subjects lacking this receptor lose control over the microbes living on the intestinal surface, both in terms of their numbers and composition.

Earlier studies suggested that breakdown of cruciferous vegetables can yield a compound that can be converted into a molecule that triggers AhRs. The new study finds that subjects fed a synthetic diet lacking this key compound experience a significant reduction in AhR activity and lose IELs. With reduced numbers of these key immune cells, they showed lower levels of antimicrobial proteins, heightened immune activation and greater susceptibility to injury. When the researchers intentionally damaged the intestinal surface in subjects that didn’t have normal AhR activity, the subjects were not as quick to repair that damage.

The immunologists involved in the research hope the findings will generate more interest in the medical community, noting that some of the basic characteristics observed in the subjects are consistent with those seen in patients with inflammatory bowel disease.

They conclude  “it’s already a good idea to eat your greens.” Still, the results offer a molecular basis for the importance of cruciferous vegetable-derived phyto-nutrients as part of a healthy diet.

Detoxification

When I was a child I was raised by my grandparents. And we lived out off of the highway back in the woods. Since we live out off of the highway my grandfather had a garden and my grandmother had chickens. So our veggies were pure, no preservatives or anything artificial. The chickens were not injected with hormone so our food was basically pretty natural.

However we had to get detox before summer and winter came around. My grandparents gave us cod liver oil for detoxification. I did not like it at that time because the fish oil smelled like fish and the oil tasted bad. But now I know that it was good for me and a good thing to do.

The detoxing kept us healthy and I don’t remember getting sick. Today we have herbal products to detox our bodies gently and safely.

Detoxing helps cleanse the liver and colon so that these organs can continue to function properly the way they were made to. Detoxification is a good thing because we ingest so many toxins from everywhere, the air, water, chemicals, skin products, food, our work environment and the list goes on. And over time these toxins stay in our bodies which cause problems down the road.

Our immune systems get weaken because of the toxins being left in our bodies that have not been eliminated. Every person is different when it comes to eliminating waste. Some of us detox naturally by going two to three times a day and then there are the rest of us that need some help!

That help for me has been herbs not the ones that my grandparents used with the fish smell but different ones. Detoxification is real and a good practice now days to do.

Immune Function

Your body’s immune system is an intricate network of cells, structures and processes that protect your body from disease and illness. When it comes to supporting immune function, single nutrients such as vitamin C may not be enough. Read on to find out more.

The complex immune system is responsible for the biodefenses of the body. Cells of the immune system play a direct role in immunity, especially through the production of antibodies and chemical messengers, substances that contribute to the complex cascade of immune events.

 

These events involve intelligent communications within the immune system and
throughout all tissues of the body. Various types of white cells circulate in
the blood or are found together in lymphatic tissues. Lymph nodes, bone marrow,
the spleen and the thymus gland contain clumps of special white blood cells
that are pivotal structures of the immune system.

 

A complex series of chemical messengers is shared among cells in the immune system. Antibody production by specific types of white cells aids in clearing the
tissue fluids of harmful intruders, e.g., antigens or microorganisms (viruses,
bacteria and yeasts). The biodefenses within the immune system are not simple in their structure or function.
Elaborate mechanisms of defense are present at entry sites into the body,
including the nasal passages, throat and entire gastrointestinal tract.

Understanding the complexity of the body structure and functions involved in immunity is a difficult task for even the most knowledgeable health care professional. This complexity makes it highly unlikely that any single drug, nutrient or botanical by itself will have an efficient overall effect on balancing or
promoting immune function. This means that immune function may be best
supported by a healthy lifestyle and the synergistic actions of combined substances (nutrients, herbs and botanicals) that support multiple components of immune function.

 

Alterations in the balance of immune function are responsible for the cause or progression of many common diseases and ailments. People talk about boosting immune function, but most often they really mean balancing or modulating immune function. Independent laboratory studies show that complex combinations of herbs, botanicals and nutrients may help to accomplish this (www.stephenholtmd.com).

The additive benefits and versatile nature of many different natural agents in a dietary supplement may work together to help support many different aspects of immune function (Table 1).

Andrographis paniculata

Acanthopanax senticosus

Green tea

Turmeric

Grape seed extract

Zinc

Vitamin C

(AHCC)

Beta glucan

Table 1: Nutrients, herbs and botanicals with scientific evidence of nutritional benefits for immune function.

Any natural agent that exerts an antioxidant function can be potentially valuable in promoting healthy immune function. This is because oxidative stress or free radical damage to components of the immune system is a common reason for impaired immunity. In particular, the following antioxidants are of value for immune support: Vitamin C, zinc, green tea, turmeric, grape seed extract and
antioxidants found in a variety of herbs and botanicals (Table 1). Botanical
agents with specific immune-enhancing properties include several species of mushrooms, plant sources of beta glucan, Echinacea and the potent and versatile herb Andrographis paniculata (AP).

Nutritional support for immune function must be multifaceted.  Formulations of dietary supplements that contain several different natural ingredients may be an optimal way to provide nutritional support for immune function, but much further research is required on the subject.
