Gut Immune Defect Links Bacteria and Metabolic Syndrome
The connection between gut bacteria and obesity has gained some weight, with new findings demonstrating links in mice among immune-system malfunction, bacterial imbalance and increased appetite.[1]
Mice with altered immune systems developed metabolic disorders and were prone to overeating. When microbes from their stomachs were transplanted into other mice, they also become obese. These latest findings add weight to the growing appreciation about the role of the bacteria in and on our bodies. We are all outnumbered in terms of human versus bacterial cells and the concept of human and bacteria symbiosis as a super-organism is gaining traction.
Already there have been strong associations between asthma, some cancers, autoimmune conditions and unwanted weight gain.

Disease Incidence Prevention by Serum 25(OH)D Level
In the last few years a considerable consensus across the scientific community has begun to emerge concerning the fat soluble nutrient Vitamin D.
Vitamin D is unique – unlike ALL other vitamins very little comes from our food. Almost all of our Vitamin D is produced by the upper surface of our skin during direct exposure to UV radiation in strong sunlight. However in the UK and most of the USA the sun is too low in the sky from November until March to produce any Vitamin D from sunlight exposure. The fat soluble nutrient supplies are meant to rely on a summer exposure to increase our stores to supply what we need during the winter.

Antioxidants Improve End Stage Cancer Survival
There remains controversy in the medical fields about the value of antioxidants, or risk of antioxidants in patients with cancer. In the Journal of International Medical research a pilot trial followed 41 patients over a 9 year period who had been diagnosed with end stage cancer. During this time they were given a mix of antioxidants including; Coenzyme Q10, vitamin C, selenium, folic acid and betacarotene.
The treatments were well tolerated and produced a > 40% increase in survival time with 76% of the patients surviving far longer than predicted. Whilst the study accounted for all participants and the disease course was well illustrated in all of the patients, there is a lack of retrospective design, matched controls and no blinding.

Expensive Urine or Effective Triage?
Victor Herbert, the outspoken Harvard nutrition scientist, was quoted by the United States well read Time magazine in a famous 1992 cover story about nutrition as saying that vitamins just gave one “expensive urine.”
This one liner has acted as a simple rebuke to the consumption of additional nutrients as food supplements – or at least the water soluble ones. It is repeated by the medical community wedded to the model that food will supply all we require, and by the skeptics who seek an easy one liner to dismiss thousands of research papers that contradict this simplistic and invalid statement.

Minerals and Vitamins Reduce the Risk of Bladder Cancer
Micronutrient deficiencies could provide a possible explanation for why an estimated 25% of the US population who consume the least fruit and vegetables have double the cancer rate.[1] The aim of our study was to investigate the association between major dietary minerals and vitamins and the risk of bladder cancer in a US population from a region with a high incidence rate.[2]
Objective: Although the effect of fruit and vegetables on the risk of bladder cancer has been widely studied, little is known about their micronutrient components. Our aim was to investigate associations between minerals and vitamins and bladder cancer.

Novel Influenza H1N1 has Dramatic Risks for Pregnant Women
Like previous epidemic and pandemic diseases, 2009 pandemic influenza A (H1N1) may pose an increased risk of severe illness in pregnant women. To see if there were clinical experiences that matched this assumption a Californian investigation by their Department of Health reviewed demographic and clinical data reported from April 23 through August 11, 2009, for all H1N1-infected, reproductive-age women who were hospitalised or died. These included non-pregnant women, pregnant women, and postpartum women (those who had delivered ≤2 weeks previously).[1]

MultiVitamin & Mineral – Why?
One of the most common questions asked by patients and people in general is why should I take a multivitamin and multimineral supplement? Dr Alex Vasquez addresses this question in a 10 minute video exploring 5 papers in a simplified format – an ideal place to send suitable questioners?
Immune Tolerance in the GUT Relies on Dendritic Cells
The differing origins of gut dendritic cells — white blood cells that modulate immune responses — may explain how the intestinal immune system manages to destroy harmful pathogens while tolerating beneficial bacteria says an article by Sophie Laffont & Fiona Powrie in Nature journal out on Dec 10th 2009.
The immune system must protect the body from invading pathogens without mounting damaging responses to its own tissues. Dendritic cells, a rare population of white blood cells, have a crucial role in determining the nature of immune reactions and in fine-tuning the balance between tolerance (where the immune system ignores or tolerates an antigen) and the induction of inflammation to destroy pathogenic organisms.

Fatty Diet Suppresses Immune System
Fresh evidence that fatty food is bad for our health has come to light: mice fed a lard-based diet over a long period got worse at fighting bacteria in the blood, reveals a thesis from the Sahlgrenska Academy based at the University of Gothenberg in Sweden.
The mice fed the lard-based diet derived 60 per cent of their total calories from fat. They were compared with mice fed a low-fat diet, where no more than ten per cent of their calories came from fat. As expected, the mice on the high-fat diet got fatter. A more surprising result was that their immune system was less active. The white blood cells got worse at dealing with bacteria in the blood, which could have contributed to many dying of sepsis.

Microbes in Mum – Act as Inhibitors of Allergy in Children
A new twist to the hygiene hypothesis shows that allergic risk can also be modulated by microbial exposure before birth. Mice born to dams that were exposed to bacteria during pregnancy were less likely to develop allergic responses than those born to unexposed mothers. And maternal Toll-like receptor (TLR) signals were required for the transmission of protection.
TLRs are a type of pattern recognition receptor (PRR) and recognise molecules that are broadly shared by pathogens but distinguishable from host molecules, collectively referred to as pathogen-associated molecular patterns (PAMPs).
