Harvard Study Confirms Fluoride Reduces Children's IQ | Dr. Joseph Mercola:
recently-published Harvard University meta-analysis funded by the
National Institutes of Health (NIH) has concluded that children who live
in areas with highly fluoridated water have "significantly lower" IQ scores than those who live in low fluoride areas.
In a 32-page report that can be downloaded free of charge from Environmental Health Perspectives, the researchers said:
A
recent report from the U.S. National Research Council (NRC 2006)
concluded that adverse effects of high fluoride concentrations in
drinking water may be of concern and that additional research is
warranted. Fluoride may cause neurotoxicity in laboratory animals,
including effects on learning and memory ...
To summarize the
available literature, we performed a systematic review and meta-analysis
of published studies on increased fluoride exposure in drinking water
and neurodevelopmental delays. We specifically targeted studies carried
out in rural China that have not been widely disseminated, thus
complementing the studies that have been included in previous reviews
and risk assessment reports ...
Findings from our meta-analyses
of 27 studies published over 22 years suggest an inverse association
between high fluoride exposure and children's intelligence ... The
results suggest that fluoride may be a developmental neurotoxicant that
affects brain development at exposures much below those that can cause
toxicity in adults ...
Serum-fluoride concentrations associated
with high intakes from drinking-water may exceed 1 mg/L, or 50 Smol/L,
thus more than 1000-times the levels of some other neurotoxicants that
cause neurodevelopmental damage. Supporting the plausibility of our
findings, rats exposed to 1 ppm (50 Smol/L) of water-fluoride for one
year showed morphological alterations in the brain and increased levels
of aluminum in brain tissue compared with controls ...
In
conclusion, our results support the possibility of adverse effects of
fluoride exposures on children's neurodevelopment. Future research
should formally evaluate dose-response relations based on
individual-level measures of exposure over time, including more precise
prenatal exposure assessment and more extensive standardized measures of
neurobehavioral performance, in addition to improving assessment and
control of potential confounders.
Hydroponics: 90% Less Water Than Conventional Farming
As more people continue to see the
prices they pay for daily necessities rise faster than their paychecks,
a growing number have become interested in the act of homesteading.
It’s never a bad idea to think of different ways to cut back on the cost
of living, and become more self-sufficient at the same time.
Hydroponics is a system of plant growth requiring little space, and
ironically little water.
Every little change that you make to try and save money adds up over
time; bringing a water bottle from home instead of purchasing one,
reusing gift wrapping paper, choosing cloth children’s diapers instead
of costly disposable ones. Growing your own food not only makes
you more self-sufficient, it saves you money, and the food is arguably
healthier-granted it’s not smothered in pesticides, fungicides, and a
myriad of other poisons.
For those who don’t have much space, time, or energy to start growing on their own. A variety of new systems have been popularized which are targeted toward the urban homesteader. Vegetables
don’t necessarily require soil to be grown, they can be grown using
just water, provided it contains the proper nutrients and fertilizers.
An increasingly popular method of growing vegetables is by using a
hydroponic system.
Hydroponic
gardening is a technique used for growing fruit, vegetables, and other
foods in a soil-less environment. It’s an ideal technique for those with
a limited space. The various systems are cost efficient as they recycle
water and nutrients, and plants are freed from diseases and pesticides
that are commonly associated with soil, among other benefits.
There are a number of hydroponic systems available to choose from,
for those who would like to utilize this method to start growing some of
their own fresh fruit and vegetables right at home. TO choose from:
Wick Hydroponics, Water Culture, Deep Water Culture, Ebb and Flow, Drip
Hydroponics, and Nutrient Film Technique.
