Edible mushrooms are a versatile functional food and have been touted as a way to preserve youth, longevity and overall health for centuries. Now nutrition researchers from Arizona State University and Pennsylvania State University are finding that they may even help boost the immune system and reduce inflammation, especially in the colon. Keith R. Martin, ASU assistant professor in nutrition, along with his Penn State colleagues, experimented with various types of mushrooms, from the more common white button to the exotic like shiitake and oyster, to see what sort of effect they had on the immune system. Their paper was published in late February in BMC Immunology, a peer reviewed online journal. "We found that the white button mushroom seemed to be the most effective in boosting the immune system, which is good because they are the most affordable," said Martin.

ScienceDaily (May 12, 2009) - Taking folic acid supplements for at least a year before conception is associated with reduction in the risk of premature birth, according to a study by Radek Bukowski (from the University of Texas Medical Branch, United States of America) and colleagues. Although most pregnancies last about 40 weeks, many babies (for example around 12% in the United States) are born before 37 completed weeks of pregnancy. Babies born prematurely are less likely to survive than full-term babies and are more likely to have breathing difficulties and learning or developmental disabilities. Currently, there are no effective methods of prevention or treatment of premature (preterm) birth, but previous studies have suggested that lower concentrations of folate (folic acid) are associated with shorter duration of pregnancy. Bukowski and colleagues therefore tested this idea, by analyzing data collected from a cohort of nearly 35,000 pregnant women. The results of this study showed that taking folate supplements for at least one year before conception was associated with a 70% reduction in spontaneous premature birth between 20 and 28 weeks (a reduction from 0.27% to 0.04%), and a 50% reduction between 28 and 32 weeks (reduction from 0.38% to 0.18%), as compared to the rate of preterm birth when mothers did not take additional folate supplementation. Folate supplementation for less than a year before conception was not linked to a reduction in the risk of premature birth in this study, and folate supplementation was not associated with any other complications of pregnancy. In a related commentary also published in this week's PLoS Medicine, Nicholas Fisk from the University of Brisbane, Australia, and colleagues (who were not involved in the original study) say "Methodologically, the study has several strengths... It is based on a huge dataset, with prospective recording of dietary supplements and potential confounders, and gestational age determined accu

Using a new, more sensitive-testing approach they developed for fungi, Penn State food scientists have found that mushrooms are a better natural source of the antioxidant ergothioneine than either of the two dietary sources previously believed to be best. The researchers found that white button mushrooms, the most commonly consumed kind in the U.S., have about 12 times more of the antioxidant than wheat germ and 4 times more than chicken liver, the previous top-rated ergothioneine sources based on available data. Until the Penn State researchers developed their testing approach, known as an assay, there was no method employing the most sensitive modern instrumentation and analytical techniques to quantify the amount of ergothioneine in fungi. The researchers say that their assay can be used for other plants, too, not just mushrooms.

A recently completed study from researchers at Colorado State University supported by the Division of Vector-Borne Infectious Diseases with the Centers for Disease Control and Prevention (CDC) has demonstrated that AHCC(R) (Active Hexose Correlated Compound) enhances host resistance by boosting protective immune responses specific to the West Nile Virus. Since its discovery in the United States in 1999, infections caused by the West Nile Virus have become a major public health concern. West Nile Virus is caused by people being bitten by mosquitoes infected with the virus. According to the CDC, there have been 28,018 reported cases with 1,092 deaths since 1999. In 2003, the highest number of cases was reported at nearly 10,000. Currently there is no effective treatment for the disease.

Can including wheat in your diet create hell on earth? Was The Inferno nothing more than Danté's prediction for the state of the U.S. diet circa 2009? I'm kidding on The Inferno allusion, but the American diet nonetheless sure does create an inferno of unhealthy phenomena.

It turns out that statins inhibit not only the liver from making cholesterol but may also block the brain from making cholesterol. That's a serious consequence, according to Yeon-Kyun Shin, a biophysics professor in the department of biochemistry, biophysics and molecular biology at Iowa State, because cholesterol is vital for healthy and optimum brain function. "If you deprive cholesterol from the brain, then you directly affect the machinery that triggers the release of neurotransmitters. Neurotransmitters affect the data-processing and memory functions. In other words, how smart you are and how well you remember things," said Dr. Shin in a statement to the media.

Faiz S, Panunti B, Andrews S. \nThe epidemic of vitamin D deficiency.\nJ La State Med Soc. 2007 Jan-Feb;159(1):17-20; quiz 20, 55.\nPMID: 17396471 [PubMed - in process]

ScienceDaily (Feb. 10, 2009) - Vitamin D is significantly associated with muscle power and force in adolescent girls, according to a new study. Although vitamin D is naturally produced in the body through exposure to direct sunlight, vitamin D deficiency has become widely common in the United States. Vitamin D deficiency has been shown to have a significant negative impact on muscle and bone health, and can lead to conditions including osteoporosis and rickets.

The Vitamin D Council is a group of concerned citizens that believe many humans are needlessly suffering and dying from Vitamin D Deficiency. We are incorporated as a nonprofit, tax-exempt 501(c)(e) educational corporation in the State of California. Our Board of Directors currently includes four physicians, including John Cannell as Executive Director. The board will eventually be expanded to 20 members.

We have compiled an Herb and Supplement Encyclopedia that you can search through to learn more about natural remedies. This herbal and supplement encyclopedia was written in an effort to provide accurate and up to date information on herbs that are commonly used in herbal preparations within Canada and the United States. Covering both their traditional usage and the latest scientific findings, each herbal monograph lists the 'traditional' usages in point form and also outlines the most well founded indications and relevant research in a short overview paragraph. The information on indications and suggested amount for each herb is largely based on the German Pharmacopoeia and other authoritative sources. We have also listed the traditional use of these herbs by First Nations healers wherever possible, out of respect and great appreciation for their healing wisdom and insight, often born out by science.

ScienceDaily (May 12, 2009) - The more pills a dialysis patients takes, the worse their health-related quality of life, according to a new study. The findings indicate that increasing the number of medications to control patients' disease may interfere with their ability to enjoy normal activities. Kidney disease patients undergoing dialysis must take more pills than most patients with other chronic diseases. While these medications are important for controlling patients' disease, at some point taking too many pills (with their ensuing side effects) may negatively affect patients' health-related quality of life, or their perceived physical and mental health. Rajnish Mehrotra, MD and Yi-Wen Chiu, MD (Los Angeles Biomedical Research Institute), and their colleagues conducted a study to see if "pill burden" affects dialysis patients' health-related quality of life. They studied 233 chronic dialysis patients from three clinics in different geographic areas in the United States. The investigators found that patients took an average of 19 pills a day and that a quarter of the patients took more than 25 pills a day. Patients with a high pill burden had lower perceived physical health. Medications called phosphate binders, which control the level of phosphorous in the blood, accounted for about half of the daily pill burden. Sixty-two percent of the patients did not take these medications as directed. The more phosphate binders a patient was prescribed, the less likely they were to take their medications as directed and the less likely they were to have their blood phosphorous levels under control. These findings indicate that increasing the number of prescribed pills does not seem to improve control of phosphorous levels and may come at the cost of poorer health-related quality of life. The authors note that any attempts to tackle dialysis patients' pill burden must address the number of phosphate binders a patient is prescribed on a daily basis. Dr. Mehrotra has re

TUESDAY, April 14 (HealthDay News) -- A particular type of stem cell transplantation using the patient's own cells led to short-term freedom from insulin injections in 20 of 23 patients newly diagnosed with type 1 diabetes participating in an experimental protocol in Brazil. One patient even managed to go four years without needing outside sources of insulin, although the average was 31 months, said the authors of a report in the April 15 issue of the Journal of the American Medical Association, a themed issue on diabetes. The patients also kept their blood sugar under control, which is key to preventing complications from diabetes. And, the authors stated, increased C-peptide levels indicated that the pancreas' beta cells were alive and well.

There is new research out this morning from South Dakota State University which offers evidence that including flax in the diet may help prevent colorectal tumors or keep tumors from growing as quickly when they do form. Professor C. Dwivedi, head of SDSU's Department of Pharmaceutical Sciences, directed the study. The study was conducted in mice that develop spontaneous intestinal tumors. This strain of mouse is often used as a model by cancer researchers due to this mutation.

Vitamin K is a fat-soluble vitamin. The "K" is derived from the German word "koagulation." Coagulation refers to the process of blood clot formation. Vitamin K is essential for the functioning of several proteins involved in blood clotting (1). There are two naturally occurring forms of vitamin K

Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.
