Does tap water make you sick?

Drinking chemical rich tap water has been linked to an increase in the occurrence of various food allergies in children and adults. The use of environmental pesticides and purifying chemicals is an all-time high and a growing health concern.

Tap water is often treated with chemicals called dichlorophenols. These chemicals are used to purify ground water so it can be consumed ‘safely’.  However, short-term safety may not be the same as long-term safety. 

According to a report in TIME Magazine, 10,348 study participants who were found to have the highest levels of dichlorophenols in the body were "80 percent more likely to have food sensitivities than those with lower levels.

"The authors believe the exposure to the chemicals may be contributing to a hyper-sensitive immune system that recognizes even common food proteins as foreign."

Although the ultimate causes of the allergic reactions are unknown, the hypersensitivity is likely to over-stimulate different systems of the body that control and regulate critical daily processes.   

Pollutants are so widely available through pesticides, herbicides and insecticides that there may to be a link said the lead researcher, Dr. Elina Jerschow, an American College of Allergy, Asthma and Immunology (ACAAI) fellow.

The authors also said that the results of the study do not create an absolute cause and effect relationship between pesticides and allergies but additional studies should further investigate the link. However, the immediate correlation should make us question and implement safe water hygiene techniques.  Simply adding chemicals to strip bacteria is not the only consideration when looking at overall health and well-being.

“In an urbanized setting, we are not exposed to the same bacteria as we used to be,” says Dr. Jerschow. “For example, kids living on farms are exposed to more bacteria and have less allergies. It could be that dichlorophenols prevent us from being exposed to more bugs.”

Children that develop food allergies are more likely to suffer from asthma, allergies and other more serious immune system diseases as well.  Healthcare is always attempting to find the best and most cost-efficient solutions but it is important to also consider possible long-term health conditions that are caused by apparent short-term solutions. 

Research has shown tap water can contain a number of the following contaminants: chlorine, heavy metals, heart medications, anti-depressants, estrogen and painkillers. 

There is no substitute for water – one’s body needs it to survive.  One cannot get it by drinking fizzy drinks, sugar-laced products, coffees or other man-made concoctions.  It may not be advised to drink straight from the tap but one needs to get it from somewhere.  

Drinking bottled water may not be the best solution either. Plastic water bottles are filled with chemicals called phthalates. These industrial chemicals have been linked to reduced sperm count, testicular atrophy and liver cancer in laboratory rats and an increase in bladder cancer in human subjects.

The best advice is to boil and filter your own water if available.  This process may not eliminate dangerous toxins such as bleach, detergents and certain molds but it will be a significant step in the right direction. 

Long-term results cannot be achieved if immediate changes are not implemented. New routines can yield new results and the ease of old conditions. Failing to plan is planning to fail. Finish 2012 off strong and commit to a healthier 2013.

Can we now cure HIV in newborns?

Doctors are reporting that a child born with HIV that was put on an unusually aggressive treatment regimen has been functionally cured of the infection. Using the most sensitive HIV testing available, they were able to find only trace amounts of HIV "particles" but no virus capable of replicating, the research team reported.

"If there is a trial that shows this can happen again, then this will be very important," said Dr. Karin Nielsen, a pediatrician who specializes in infectious diseases at UCLA's David Geffen School of Medicine. "You'll be able to treat people very intensively and reverse the disease."

The news provides no answers for adults living with HIV but it can be a landmark victory in the health of future generations. Every year, 300,000 to 400,000 babies are born infected with HIV according to Dr. Anthony Fauci, head of the National Institute for Allergies and Infectious Diseases.

The treatment consisted of giving the newborn a three-drug…

Non-communicable diseases ravaging the poorest

The convergence of non-communicable diseases (NCDs) and infectious diseases (IDs) in low- and middle-income countries presents major challenges to the world’s poorest and most neglected groups of people. NCDs continue to escalate and cause hundreds of billions of dollars of loss annually despite aggressive lifestyle campaigns.

A NCD is a medical condition or disease that is non-infectious and non-transmissible amongst people. NCDs may be chronic diseases of long duration and slow progression, or they may result in more rapid death such as some types stroke and heart attacks. Unknowingly to most, NCDs also include autoimmune diseases, many cancers, asthma, diabetes, chronic kidney disease and many more.

Most Low- to middle income countries has dual disease burdens of NCDs and IDs including tuberculosis, HIV/AIDS and parasitic diseases. Unfortunately, experts, institutions and policies that support prevention and control of these two overarching disease categories have very limited int…

Strong health systems critical in addressing health threats in the African Region

Brazzaville, 8 April 2015 – The World Health Organization (WHO) Regional Director for Africa, Dr Matshidiso Moeti has called on the Diplomatic Corps accredited to the Republic of Congo to advocate with their national governments to strengthen health systems to be able to address the health challenges facing the African Region. She briefed the diplomats about the on-going Ebola epidemic in West Africa, current and emerging health threats in the WHO African Region, progress towards the Millennium Development Goals (MDGs), and the strategic priorities for WHO’s work in the Region for 2015-2020. The Regional Director underscored the importance of strong national health systems to be able to withstand epidemics and emergencies while delivering essential health services to people who need them most. Dr Moeti pointed out that the Ebola epidemic has had devastating impacts on families, livelihoods, security, health workforce, service delivery and overall socioeconomic development of the seve…
