Boek over 'algen-antioxidant' astaxanthine van Gert Schuitemaker

De sterkste antioxidant uit het water heet astaxanthine. Dr. Gert Schuitemaker schreef een boek over dit veelzijdige voedingssupplement, dat veroudering kan helpen vertragen. Lang leven in een goede gezondheid. Wie wil dat niet? Toch grijpen de kwaaltjes en ziekten van alledag om zich heen. Ze zijn het gevolg van processen die zich op een dieper niveau in ons lichaam afspelen. Deze processen resulteren in het ene geval in een 'plotselinge' hartaanval, in het andere geval verlopen ze langzaam maar merkbaar. Denk aan opkomende ochtendstijfheid, het krijgen van een buikje, de eerste rimpels en een afname van conditie en kracht.

Dit willen we allemaal graag voorkomen, of minstens zo lang mogelijk uitstellen. Kennis omtrent 'oxidatieve stress' en de 'stille ontsteking' is hierbij cruciaal. Dit zijn processen waarbij het immuunsysteem een belangrijke rol speelt. Aan de hand van de veelomvattende werking van astaxanthine laat dit proces van 'oxidatieve stress' en 'stille ontsteking' zich bijzonder goed uitleggen. Astaxanthine heeft immers vele uitzonderlijke kwaliteiten op verschillende plaatsen in het lichaam. Dit boek geeft dan ook een dieper inzicht in onze gezondheid aan de hand van het verhaal over astaxanthine, de algen-antioxidant.

We zijn door de jaren vertrouwd geraakt met de antioxidanten die vruchten van het land zo prachtig rood of donkerblauw kleuren en die voor ons zo supergezond zijn. Astaxanthine is een algen-antioxidant uit het water met een dieprode kleur. Het is de stof die waterdieren zoals de flamingo, de zalm en de kreeft rood kleurt.

Astaxanthine is een antioxidant die tegenwoordig te weinig voorkomt in ons dagelijkse menu, maar in feite een 'oerbeschermer' is. In zijn voorwoord stelt dr. Frits Muskiet dan ook de vraag of astaxanthine moet worden gerekend tot de 'oermoleculen', die reeds werden gebruikt door de eerste levende wezens op aarde. Tot deze moleculen behoren onder andere onmisbare stoffen als vitamine D en de omega 3-vetzuren DHA en EPA. Muskiet juicht het toe dat met dit boek eindelijk de aandacht wordt gevestigd op de nog tamelijk onbekende stof astaxanthine.

Are BioAlgae Concentrates Effective for Radiation Poisoning

Last week, I had a chance to speak with Roland Thomas, ND about BioAlgae Concentrates... This is a special blend of algae that has been studied quite significantly over the past few decades. In this clip, Roland discusses some of the scientific studies that this algae had been used in and some of the results. I think the most shocking is the research done on chickens in Russia and the use of this algae on radiation poisoning victims of the Chernobyl disaster. These studies were done using a blend of algae called BioAlgae Concentrate that contains spirulina and chlorella.


Spirulina - Marcus Rohrer

Spirulina is a powerhouse that stores and converts enormous quantities of solar power into precious vitamins, minerals and energy like no other plant. Scientists have discovered that energy from the sun is extremely important for our health. It is mainly found in fresh vegetables and sun-ripened fruit. This is one of the reasons that they are so good for you. Research has also proven that fresh Spirulina is one of the richest sources of solar power!

Montana State team finds Yellowstone alga that detoxifies arsenic

Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. The alga -- a simple one-celled algae called Cyanidioschyzon -- thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally around hot springs, said Tim McDermott, professor in the Department of Land Resources and Environmental Sciences at Montana State University. Cyanidioschyzon could someday help reclaim arsenic-laden mine waste and aid in everything from space exploration to creating safer foods and herbicides, the scientists said. The alga and how it detoxifies arsenic are described in a paper that's posted this week (week of March 9) in the online edition of Proceedings of the National Academy of Sciences, or PNAS. Lead authors are McDermott and Barry Rosen, of Florida International University. Among the four co-authors is Corinne Lehr, who formerly worked with McDermott as a postdoctoral scientist at MSU and is now a faculty member at California Polytechnic State University. Arsenic is the most common toxic substance in the environment, ranking first on the Superfund list of hazardous substances, the researchers wrote in their paper. McDermott said arsenic is very common in the hot, acidic waters of Yellowstone and presents real challenges for microorganisms living in these conditions. Indeed, there are challenges for the researchers. McDermott said the acid in the soil and water are strong enough that it sometimes eats holes through his jeans when he kneels to collect samples. McDermott has worked in Yellowstone for more than a decade and travels year-round to the Norris Geyser Basin to study the microbial mats that grow in acidic springs. Over the years, he noticed thick algae mats that were so lush and green in December that they looked like Astro-Turf, McDermott said. By June, they were practically gone. While investigating the change, McDermott and his collaborators learned about the Cyanidiales alga and its ability to reduce arsenic to a less dangerous form. "These algae are such a dominant member of the microbiology community that they can't escape notice, but for some reason they have not attracted much attention," McDermott said.

Algae - Anti-cancer vegetables grown in the sea

Marine algae truly are the prototype of the ideal health food. Since algae absorb nutrients through their anatomical structures (a bit like a sponge), they contain all or substantially all essential minerals, such as iodine, potassium, iron and calcium (some algae contain up to 10 times the calcium in cow's milk and five times the iron in spinach!).

Protein from Algae Shows Promise for Stopping SARS

A protein from algae may have what it takes to stop Severe Acute Respiratory Syndrome (SARS) infections, according to new research. A recent study has found that mice treated with the protein, Griffithsin (GRFT), had a 100 percent survival rate after exposure to the SARS coronavirus (SARS-CoV), as compared to a 30 percent survival for untreated mice.

Genes from tiny marine algae suggest unsuspected avenues for new research

By sequencing the DNA of two tiny marine algae, a team of scientists has opened up a myriad of possibilities for new research in algal physiology, plant biology, and marine ecology. The project was led by Alexandra Worden at the Monterey Bay Aquarium Research Institute (MBARI) and the Joint Genome Institute (JGI). The genome analyses involved a collaborative effort between MBARI, JGI, and an international consortium of scientists from multiple institutions, including University of Washington, Ghent University (Belgium), and Washington University in St. Louis. Initial discoveries from the research appear in the April 10, 2009 edition of Science magazine. Biologists generally agree that all land plants, from tiny mosses to giant redwoods, evolved from an ancestral green alga. Some of the closest representatives of these ancestral green algae living today are thought to be the Prasinophytes, a group of microscopic green algae found across the world's oceans. Microbial oceanographer Alexandra Worden led a team of scientists that sequenced the genomes of two Prasinophytes in the genus Micromonas. Each Micromonas cell is only about one fiftieth the width of a human hair. However, they are widespread and may serve as important links in marine food webs. They may also influence the amount of carbon dioxide the oceans take up from the atmosphere. Worden's team spent four years compiling a complete list of the approximately 21 million chemical building blocks (called bases) that make up Micromonas' DNA. The recent Science paper highlights key aspects of this genetic "Morse code." The paper also compares Micromonas' genes with genes found in other organisms.

ISU researcher identifies protein that concentrates carbon dioxide in algae

Increasing levels of carbon dioxide in the atmosphere are a concern to many environmentalists who research global warming. The lack of atmospheric carbon dioxide (CO2) concentration, however, actually limits the growth of plants and their aquatic relatives, microalgae. For plants and microalgae, CO2 is vital to growth. It fuels their photosynthesis process that, along with sunlight, manufactures sugars required for growth. CO2 is present in such a limiting concentration that microalgae and some plants have evolved mechanisms to capture and concentrate CO2 in their cells to improve photosynthetic efficiency and increase growth. An Iowa State University researcher has now identified one of the key proteins in the microalgae responsible for concentrating and moving that CO2 into cells.

Chalk one up for coccolithophores

Scientists have feared that gradual acidification of the world's oceans would wreak havoc with organisms that build protective outer shells. But a new finding shows at least three species of coccolithophores – single-celled algae that are major players in the ocean's cycling of carbon – are responding to ocean acidification by building thicker cell walls and plates of chalk, contrary to what some recent lab experiments have shown.
