The Miracle Antioxidant and Anti-Inflammatory Nutrient

For years, I've been a strong proponent of astaxanthin, a remarkable nutrient sometimes called "King of the carotenoids!" Derived from microalgae (and also found in wild salmon), astaxanthin is on my list as one of the top three most important nutrients for human health. I take an astaxanthin supplement (BioAstin) every day.

Today, I bring you a collection of quotes from authors talking about this amazing nutrient. And yet this collection barely scratches the surface of the whole story on astaxanthin

Authors' Quotes on Astaxanthin

The study found that mice that were fedastaxanthinand then run on a treadmill until exhaustion suffered less heart damage than mice that were similarly exercised withoutastaxanthinsupplementation. On examination, they foundastaxanthinconcentrated in the mice's hearts. They concluded thatastaxanthincan decreaseexerciseinduced damage in the heart as well as in the skeletal muscle (Aoi, et al, 2003). At the Medical College of Wisconsin, another animal study withratsshowed cardio-protective attributes forastaxanthin. In this study,astaxanthinwas given to rats prior to heart attacks.

Spirulina and Chlorella Aid Heavy Metal Detox

Tuesday, December 15, 2009 by: Elizabeth Walling

From aluminum in deodorant to mercury in dental fillings, metal toxicity comes at us from every angle these days. The presence of these heavy metals (and others such as arsenic, cadmium and lead) has increased as industrialization and its waste products spread. We can work to avoid these substances as much as possible, but some exposure will still occur at times. Since even small amounts of heavy metals in the body can cause negative side effects like fatigue, headaches, digestive problems and skin conditions, it's important to use natural methods to cleanse your body of these toxins.

Why Spirulina and Chlorella Are Effective for Heavy Metal Detox

The answer to natural heavy metal detoxification is as simple as a single-celled organism. Spirulina and chlorella are two separate micro-algae organisms which have existed on earth since the dawn of time. Both were revered as powerful superfoods in many traditional societies, and today are more relevant than ever for achieving overall health and well-being.

Spirulina has been shown as an effective chelating agent for removing toxins such as mercury, and radioactive substances from the body. It has also been used to remove cadmium and lead from waste water.

While some detoxifying supplements simply release toxins from cells and tissues, chlorella is particularly adept at binding to toxic metals and ushering them out of the entire system. Chlorella contains proteins and peptides which are designed to bind to these substances and carry them out of the body. The chlorophyll in chlorella also aids heavy metal detoxification.

Other Amazing Health Benefits

Just as important as their ability to detox heavy metals, both spirulina and chlorella exhibit strong healing and regenerating capabilities. They are filled with beneficial vitamins, minerals, proteins and fats which work together in a synergistic way to provide energy and vitality.

Appropriate Dosage

Spirulina and chlorella can be used in very high doses for heavy metal detox. Because they are so effective at binding toxins and purging them from the body, they can actually reduce some of the common side effects associated with detoxification. A typical dosage of spirulina or chlorella for heavy metal detox is about 20 - 30 grams per day. They can be used together if desired. You may want to start with as little as 500mg daily and work up as needed to allow your body to adjust. After completing detox, you can taper down to a maintenance dosage of 3 - 6 grams per day.

It's important to find a manufacturer of spirulina or chlorella who takes the proper steps to ensure a clean and digestible product free from fillers and additives. A little research can reveal which manufacturers are the most reputable.

Study: fluoridated water causes brain damage in children

Thursday, December 23, 2010 by: Ethan A. Huff, staff writer


A new study pre-published in the journalEnvironmental Health Perspectivesconfirms that fluoridated water causes brain damage in children. The most recent among 23 others pertaining to fluoride and lowered IQ levels, the new study so strongly proves that fluoride is a dangerous, brain-destroying toxin that experts say it could be the one that finally ends water fluoridation.

"This is the 24th study that has found this association," explained Paul Connett, Ph.D., director of the Fluoride Action Network (FAN). "[B]ut this study is stronger than the rest because the authors have controlled for key confounding variables and in addition to correlating lowered IQ with levels of fluoride in the water, the authors found a correlation between lowered IQ and fluoride levels in children's blood."

For the study, researchers evaluated 512 children ages 8-13 in two Chinese villages, one village with higher than average fluoride levels and the other with lower than average fluoride levels. After accounting for external variables like lead exposure, iodine deficiency and other conditions that might affect brain health, the team still found that the number of higher intelligence children in the low fluoride community was 350 percent higher than the number in the high fluoride community.

"In this study we found a significant dose-response relation between fluoride level in serum and children's IQ," wrote the study authors.

Though there have been numerous studies over the years the identify fluoride as a neurotoxin, most mainstream medical professionals in the U.S. have ignored them and continue to support water fluoridation. But the evidence continues to mount, and sooner or later the medical community will have to come to grips with the truth about fluoride.

"This should be the study that finally ends water fluoridation," explained Tara Blank, Ph.D., Science and Health Officer at FAN. "Millions of American children are being exposed unnecessarily to this neurotoxin on a daily basis. Who in their right minds would risk lowering their child's intelligence in order to reduce a small amount of tooth decay, for which the evidence is very weak."

Fluoride means lower IQs and more mental retardation

Thursday, January 06, 2011 by: Kim Evans

Researchers recently looked at the IQs of 512 Chinese grade-schoolers from two otherwise similar villages, except for the amount of fluoride they were drinking in their water. In the village with high fluoride in their water, the children were less intelligent - and far more apt to be mentally retarded - than the children from the village with low fluoride in the water. Actually, the children drinking less fluoride had about half the fluoride in their blood - and on average, an IQ about 8 points higher.

The Chinese children were drinking well water with naturally occurring fluoride. However, in the U.S., governments often mandate water fluoridation. Seventy percent of the water in the U.S. is fluoridated and even by drinking purified water, most people absorb a gallon of fluoridated water in each shower.

In the low fluoride village, about 28 percent of the children had IQs indicating bright normal or high intelligence. However, in the high fluoride village less than a third of that number - only about 8 percent - had bright normal or high intelligence. In the village with more fluoride, over 15 percent of the children had IQs indicating mental retardation or borderline retardation; whereas, only about 6 percent in the low fluoride village had this problem. The results were clear: the children drinking more fluoride were about two and a half times more likely to have mental retardation.

In either of the villages, the children with scores showing mental retardation or borderline retardation had more fluoride in their blood than any of the other children. The researchers state, "As the fluoride level in children's serum increased, the children's IQs fell and the rates of borderline or lower intelligence increased." Of course, it's impossible to say what the children's IQs would have been, even in the low fluoride village, if they - and their parents - haven't been exposed to fluoride in their water at all. One can bet they would have been much higher.

In the high fluoride village, the average fluoride in the water was 2.47 mg/L (milligrams per liter). In the low fluoride village, the average was .36 mg/L. In the U.S., the CDC recommends water fluoridation between 0.5 to 1.2 mg/L and considers water with 0.7 mg/L or higher to have "substantial" fluoride. The EPA's maximum for fluoride in our water is 4 mg/L - which is well over the amount causing retardation in these children. In the U.S., about one in ten children has a learning disability.

According to the CDC, over forty percent children from 12 to 15 also have dental fluorosis. Dental fluorosis is caused by high exposure to fluoride (some would say fluoride poisoning) and is characterized by visible white stains on the teeth. About two dozen human studies link fluoride with low IQ and over a hundred animal studies link fluoride to brain damage. Still more research connects fluoride with thyroid disease and cancer. Many countries around the world add fluoride to the salt, if it's not easy to reach the population through the water supply.

[Editor`s Note: NaturalNews is strongly against the use of all forms of animal testing. We fully support implementation of humane medical experimentation that promotes the health and wellbeing of all living creatures.

De simples analyses de salive et de sang pourraient détecter l’épuisement professionnel avant qu’il ne se manifeste

22 février 2011 par Planet Techno Science   
Classé sous Biologie, Biologie humaine / Médecine


MONTRÉAL, le 22 février 2011 – Selon une recherche entreprise par la professeure Sonia Lupien et Robert-Paul Juster, du Centre d’études sur le stress humain de l’Hôpital Louis-H.-Lafontaine et de l’Université de Montréal, votre sang et le niveau d’une hormone dans votre salive pourraient révéler si vous êtes sur la voie de l’épuisement professionnel.

En plus de la souffrance professionnelle et personnelle, le burn-out, s’il est ignoré, soumet les travailleurs en détresse à des risques supplémentaires de problèmes physiques et psychologiques.

Il s’agit d’un fait significatif, puisque, selon les évaluations de l’Organisation mondiale du travail, l’épuisement professionnel, la dépression clinique ou l’anxiété en milieu de travail touchent au moins 10 pour cent des Nord-Américains et des Européens. 


« Nous avons émis l’hypothèse que des travailleurs en santé souffrant de stress chronique et de symptômes mineurs d’épuisement professionnel présenteraient des dérèglements physiologiques plus grands et des niveaux moins élevés de cortisol, un profil associé à l’épuisement professionnel», a expliqué monsieur Juster.


Le cortisol est une hormone de stress qui joue un rôle dans la réaction au stress de notre organisme et dans son rythme naturel quotidien. Les niveaux de cortisol sont souvent élevés chez les personnes qui souffrent de dépression, alors qu’ils tendent à être bas dans les cas d’épuisement professionnel.

Quand il est question de santé mentale et physique, un surplus de cortisol pourrait être aussi nocif qu’une insuffisance.

Le stress chronique et des niveaux déséquilibrés de cortisol peuvent exercer une sorte d’effet domino sur les systèmes biologiques reliés. Le terme « charge allostatique » fait référence aux problèmes physiologiques de l’usure qui résultent de ces différents systèmes et qui sont reliés aux risques de diabète, de maladie vasculaire cardiaque et de problèmes immunitaires.

En examinant différents facteurs comme l’insuline, le sucre, le cholestérol, la tension artérielle et l’inflammation, on peut établir l’indice de charge allostatique, qu’on utilise ensuite pour détecter les problèmes avant qu’ils ne surviennent. « La force du modèle de la charge allostatique est son inclusion flexible de nombreux systèmes biologiques qui sont drainés par le stress chronique.

L’utilisation complémentaire d’échantillons de salive et de questionnaires validés nous permet d’aller au-delà de la mesure des risques de syndromes métaboliques ou de problèmes cardiaques, par exemple, mais aussi de pénétrer le cœur de la maladie mentale », a précisé Robert-Paul Juster.

Les résultats de cette première étude pilote ont été obtenus en testant 30 participants d’âge moyen. En plus de faire subir aux participants des mesures sanguines de routine qui évaluent la charge allostatique, on leur a demandé de recueillir de la salive chez eux et pendant une visite en laboratoire. Ils ont aussi rempli des questionnaires à propos de leurs niveaux de stress actuels et de symptômes de dépression et d’épuisement professionnel.

Cette étude fait partie d’une grande volonté de perfectionner la médecine personnalisée dans ce domaine.

La médecine personnalisée cible l’individualisation des traitements, selon les besoins de chacun. « Dans un effort pour faire progresser les démarches orientées vers la personne dans les stratégies de prévention et de traitement, nous devons étudier les signatures biopsychosociales de maladies spécifiques », a affirmé Sonia Lupien. « Pour des conditions comme l’épuisement professionnel, où il n’y a pas de consensus sur les critères de diagnostic et où il existe un chevauchement des symptômes avec la dépression, il est essentiel d’utiliser de multiples méthodes d’analyse.

Une signature possible de l’épuisement professionnel pourrait être la diminution de la production de l’hormone de stress, le cortisol, et des dérèglements des systèmes physiologiques qui interagissent avec cette hormone de stress. » 

Malheureusement, les gens qui souffrent d’épuisement professionnel sont souvent traités avec des antidépresseurs qui réduisent le niveau de cortisol.

Si ce dernier est déjà inférieur à ce qu’il devrait être, ce type de traitement pourrait représenter une erreur thérapeutique. « L’utilisation d’un indice de charge allostatique ouvre aux chercheurs et aux cliniciens une fenêtre sur la façon dont le stress chronique épuise la personne. À l’avenir, nous avons besoin d’études qui suivent les gens au fil du temps pour déterminer si le profil d’un taux peu élevé de cortisol et de dérèglements physiologiques correspond bel et bien à la signature de l’épuisement professionnel. Si c’est le cas, la science aura progressé d’un pas vers l’aide aux travailleurs en détresse avant leur épuisement professionnel», fait remarquer monsieur Juster.

Evidence of direct cell-cell fusion in Borrelia by cryogenic electron tomography.


Parasitology, Department of Infectious Diseases, University of Heidelberg Medical School, Im Neuenheimer Feld 324, 69120 Heidelberg, Germany. Department of Molecular Structural Biology, Max Planck Institute for Biochemistry, Am Klopferspitz 18, 82152 Martinsried, Germany. Institute for Immunology, University of Heidelberg Medical School, Im Neuenheimer Feld 305, 69120 Heidelberg, Germany.




Some Borrelia species are the causative agents of tick-borne Lyme disease responsible for different disabilities depending on species and hosts. Borrelia are highly motile bacterial cells, and light microscopy shows that these spirochetes can associate with each other during movement. Using cryo-electron tomography, we observed closely associated Borrelia cells. Some of these showed a single outer membrane surrounding two longitudinally arranged cytoplasmic cylinders. We also observed fusion of two cytoplasmic cylinders and differences in the surface layer density of fused spirochetes. These processes could play a role in the interaction of Borrelia species with the host's immune system

CD14 signaling reciprocally controls collagen deposition and turnover to regulate the development of lyme arthritis.
Am J Pathol Feb 2011; 178(2) :724-34

Center for Immunology and Microbial Disease, Albany Medical College, Albany, New York, USA.



CD14 is a glycosylphosphatidylinositol-anchored protein expressed primarily on myeloid cells (eg, neutrophils, macrophages, and dendritic cells). CD14(-/-) mice infected with Borrelia burgdorferi, the causative agent of Lyme disease, produce more proinflammatory cytokines and present with greater disease and bacterial burden in infected tissues. Recently, we uncovered a novel mechanism whereby CD14(-/-) macrophages mount a hyperinflammatory response, resulting from their inability to be tolerized by B. burgdorferi. Paradoxically, CD14 deficiency is associated with greater bacterial burden despite the presence of highly activated neutrophils and macrophages and elevated levels of cytokines with potent antimicrobial activities. Killing and clearance of Borrelia, especially in the joints, depend on the recruitment of neutrophils. Neutrophils can migrate in response to chemotactic gradients established through the action of gelatinases (eg, matrix metalloproteinase 9), which degrade collagen components of the extracellular matrix to generate tripeptide fragments of proline-glycine-proline. Using a mouse model of Lyme arthritis, we demonstrate that CD14 deficiency leads to decreased activation of matrix metalloproteinase 9, reduced degradation of collagen, and diminished recruitment of neutrophils. This reduction in neutrophil numbers is associated with greater numbers of Borrelia in infected tissues. Variation in the efficiency of neutrophil-mediated clearance of B. burgdorferi may underlie differences in the severity of Lyme arthritis observed in the patient population and suggests avenues for development of adjunctive therapy designed to augment host immunity.

European neuroborreliosis: quality of life 30 months after treatment.
Acta Neurol Scand Feb 2011;

Department of Neurology, Sørlandet Hospital, Arendal, Norway Department of Neurology, Sørlandet Hospital, Kristiansand, Norway Department of Clinical Medicine, University of Bergen, Bergen, Norway Clinic of Rehabilitation, Sørlandet Hospital, Kristiansand, Norway.



Eikeland R, Mygland Å, Herlofson K, Ljøstad U. European neuroborreliosis: quality of life 30 months after treatment. Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2010.01482.x. © 2011 John Wiley & Sons A/S. Objectives -  The prognosis after Lyme neuroborreliosis (LNB) is debated. The aim of this study was to assess health-related Quality of Life (QoL) and neurological symptoms 30 months after treatment in European patients with LNB. Materials and methods -  In a prospective case-control designed study, we investigated 50 well-characterized patients with LNB who had participated in a treatment trial for LNB 30 months earlier and 50 matched control persons with the health QoL questionnaire Short-Form 36 (SF-36), the Fatigue Severity Scale (FSS), the Montgomery and Åsberg Depression Rating Scale (MADRS), the Starkstein Apathy Scale (SAS), and the Mini Mental State (MMS). Clinical and demographic data were collected by semi-structured interviews and clinical neurological examination. Results -  Lyme neuroborreliosis-treated patients scored lower than control persons in the SF-36 domains physical component summary (PCS) (44 vs 51 P < 0.001) and mental component summary (MCS) (49 vs 54 P = 0.010). They also scored lower than control persons in all the SF-36 subscales, except for bodily pain, and on FSS (3.5 vs 2.1 P < 0.001), but not on MMS (28 vs 29 P = 0.106). There was a difference in MADRS (3.1 vs 0. 8 P = 0.003) and SAS (13 vs 11 P = 0.016), but the scores were low in both groups. Fatigue was the most frequently reported symptom among LNB-treated patients (50%). Patients who reported complete recovery (56%) after LNB had similar QoL scores as the controls. Conclusion -  European persons treated for LNB have poorer health-related QoL and have more fatigue than persons without LNB

Postural orthostatic tachycardia syndrome following Lyme disease.

Cardiol J 2011; 18(1) :63-6



Background: A subgroup of patients suffering from Lyme disease (LD) may initially respond to antibiotics only to later develop a syndrome of fatigue, joint pain and cognitive dysfunction referred to as 'post treatment LD syndrome'. We report on a series of patients who developed autonomic dysfunction in the form of postural orthostatic tachycardia syndrome (POTS). Methods: All of the patients in this report had suffered from LD in the past and were successfully treated with antibiotics. All patients were apparently well, until years later when they presented with fatigue, cognitive dysfunction and orthostatic intolerance. These patients were diagnosed with POTS on the basis of clinical features and results of the tilt table (HUTT) testing. Results: Five patients (all women), aged 22-44 years, were identified for inclusion in this study. These patients developed symptoms of fatigue, cognitive dysfunction, orthostatic palpitations and either near syncope or frank syncope. The debilitating nature of these symptoms had resulted in lost of the employment or inability to attend school. Three patients were also suffering from migraine, two from anxiety and depression and one from hypertension. All patients demonstrated a good response to the employed treatment. Four of the five were able to engage in their activities of daily living and either resumed employment or returned to school. Conclusions: In an appropriate clinical setting, evaluation for POTS in patients suffering from post LD syndrome may lead to early recognition and treatment, with subsequent improvement in symptoms of orthostatic intolerance. (Cardiol J 2011; 18, 1: 63-66).
