Mississippi dubious winner of fattest state contest
This LAT article is representative of many articles this week that reports on a study issued by Trust for America's Health regarding how America is losing the battle against obesity, state by state. The actual study can be found here on Trust for Americas website. The site also has an interactive feature that shows state by state results and information.
The results show that Mississippi is the number 1 state in obesity with a whopping 30% of its residents classified as obese. The District of Columbia holds the dubious position of number 1 for childhood obesity with 22.8 % of its children obese.
The LAT article quotes Jim Marks, a senior vice president of the Robert Wood Johnson Foundation, a healthcare philanthropy group that sponsored the study as follows:
The report is a devastating indictment and the nation is in the middle of a public health crisis that is deteriorating rapidly, and we are treating it like an inconvenience.
These children could be the first generation to live sicker and die younger than their parents,"
Obesity costs $117 billion a year in preventable healthcare expenditures and "is pushing the healthcare system to the breaking point.
The LAT article also makes clear that the data is based on self reporting, hence the results are probably much worse and people do tend to understate their weight.
This report is no surprise. America seems content to ignore the obesity epidemic. But by ignoring it, we will pay as individuals and collectively as a society in higher health costs and a lower quality of life.
Cranberries offer exceptional health benefits
Cranberries, eaten fresh or dried or consumed through cranberry juice, are one of the best fruits to eat that promote good health. The number of positive health impacts from cranberries is truly amazing.
Here is information extracted directly from the Cranberry Institute Web page.
The majority of physicians and other health professionals believe there is a clear association between a diet high in fruits and vegetables and a low risk of chronic disease. Phytonutrients (naturally derived plant compounds), particularly antioxidants, are increasingly being shown to help optimize human health.
Cranberries contain proanthocyanidins (PACs) that can prevent the adhesion of certain of bacteria, including E. coli, associated with urinary tract infections to the urinary tract wall. The anti-adhesion properties of cranberry may also inhibit the bacteria associated with gum disease and stomach ulcers.
Recent scientific research shows that cranberries and cranberry products contain significant amounts of antioxidants and other phytonutrients that may help protect against heart disease, cancer and other diseases.
Rats fed diets supplemented with cranberries are put through a series of tests to evaluate their neural function compared to a control group. Preliminary results indicate that there will be compelling evidence that cranberry can help protect the brain from neurological damage.
Atherosclerosis, in the simplest terms, is the accumulation of low density lipoprotein (LDL), or "bad cholesterol", in arteries resulting in restricted blood flow. In the advance stages of the disease blood flow may be decrease severely or cease completely resulting in angina (chest pain), a thrombosis (blood clot) and/or myocardial infarction (heart attack). Atherosclerosis is a primary cause of cardiovascular disease. Ongoing research continues to suggest that cranberries may offer a natural defense against atherosclerosis.
Researchers at the University of Western Ontario demonstrated, using an animal model, that human breast cancer cells showed significantly lower incidence of tumor development when the experimental group's diet was supplemented with cranberries. Although these results are very preliminary, compounds in cranberries may prove to be a potent cancer fighter.
Here is more on the health benefits of Cranberries from WebMD.
A plant compound, called proanthocyanidin A-1 is found in cranberries. Herpes simplex-2 is one of the most common viral infections in humans. It causes genital sores or ulcers, as well as inflammation of the brain and infection of newborns and people with weakened immune systems.
Scientists' lab tests showed that proanthocyanidin A-1 helped combat herpes simplex-2: it interfered with the virus when it tried to latch onto and penetrate cells -- a necessary step for infection by the herpes virus."

Xenotransplants - the pig or not the pig
The scientific community has been in a heated debate about xenotransplants (transplanting pig islets into humans). Although the procedures are showing to be effective - is the insulin secretion entirely pig? Some experts surmise that after the transplants, diabetic patients are actually able to produce some insulin on their own, after all.
The latest press release from Tissera, Inc (an Israeli-based company) made a statement that raises my hopes. It was, "By the fourth month after transplantation, the insulin dose needed to maintain near-normal blood sugar levels decreased by more than 90% in comparison with the insulin dose needed before transplantation, meaning that endogenous insulin production was predominantly responsible for blood sugar control."
The question of the origin of endogenous insulin was addressed by measurement of blood C-peptide. C-peptide splits from insulin and indicates the level of insulin secretion from the patient. C-peptide levels were measured both at baseline and in response to a sugar load, which brings about a rise in blood C-peptide. The measured C-peptide was shown to be predominantly of pig origin. So herein lies my question: is predominantly more than 50%? A type 1 diabetic has undetectable levels of C-peptide. Period. After the xenotransplant the C-peptide level is all of a sudden detectable? Could these islet transplants assist in regenerating the diabetics' own islets?

Australian obesity crisis fuels diabetes epidemic
Type 2 diabetes, mate? By crikey. Australia's diabetes epidemic continues to be a problem. News this week indicates the spread of obesity, and with it associated conditions like Type 2 diabetes, in rural areas is far worse than previously realized. A survey of 806 randomly selected adults (okay, not the biggest sample, admittedly) found that a great many are affected by the disease. Based on their findings from that survey, researchers calculate that almost three-quarters of Aussie men living in rural areas are overweight. They think women in rural areas may be slightly better-off - around two-thirds may be overweight. This puts rural Australians at a very high risk for T2DM. The conclusion, stated in the Medical Journal of Australia: "urgent population-wide action is required to tackle the problem."
As is the case in the US, a big concern is how to treat all those people as they age and their overall health worses. Specifically, what will become of Australia's public healthcare system? "We might get a whole generation, now in their 40s, 50s and 60s, who will do markedly worse than their parents," predicts lead researcher for the study, Professor Edward Janus of Melbourne's Western Hospital.

Landmark agreement in California for students with diabetes
Most school cafeterias and vending programs feed our kids junk, but even worse, students with diabetes are not provided legally required care to manage the disease during school hours. Children with insulin dependent diabetes are heading to school without the assurance of regular blood glucose testing, the administration of insulin or other diabetes care tasks.
In 2005, four California families and the American Diabetes Association (ADA) filed a suit in San Francisco, alleging some California school districts were not providing adequate diabetes care. In some cases, parents were called to give aid before summoning a school nurse. Michelle Ferry was one such parent. When her son was in first grade, this widowed mother of four had to hire a babysitter so she could head to school to give her son an insulin shot. Risky business for her son, let alone expensive for the Ferry family. What if she could not secure a babysitter and her son ran high blood sugars? This is outrageous and unacceptable. This is just one example, many schools across the country are not adequately serving students with diabetes.
The lawsuit has been settled, and per the agreement, the California Department of Education will now require districts to ensure all children with diabetes have access to proper diabetes care during the school day. What took so long? Students with type 1 diabetes have been in public schools for years! Now a volunter school employee can be trained to assist a student with diabetes. San Ramon Valley school district claimed they wanted this ability, but they were following state regulations that care be provided by a health practitioner. State law outlines seven different categories of caregivers -- which includes a self-administering student, a school nurse or other health professional and family/friends. Now the agreement states if a licensed health professional is unavailable, a trained, unlicensed school employee may provide insulin shots per individual physician order. Hallelujah -- may California trigger a domino effect nationwide.
Jack O'Donnell, State Superintendent of Public Instruction, explained a lack of resources, uncertainty of how to best deliver services, and lack of clarity about state and federal requirements combined to cause hardship to some parents of children with diabetes. He said no parent should have to risk their job to care for their child. What his statement truly lacks is concern for the student with diabetes -- O'Donnell misses the point when he disregards the cumulative, tragic complications of poor blood glucose control.
A big legal team contributed to this win. Hats off to the ADA, attorneys with the Disability Rights Education and Defense Fund and the generous law firm of Reed Smith LLP (donor of $2.6 million in pro bono legal services). Here is the announcement of this landmark agreement and a story from Inside Bay Area.
