Want an easy way to be good to your body? Stay hydrated by guzzling
down more water throughout the day. Water has zero calories, so it
doesn't add to your waistline. Plus, it aids in just about every
bodily function, including fat burning and energy production.
Unfortunately, the water that comes out of your tap may not be
free of flaws. Water authorities do not yet regulate many
endocrine-disrupting chemicals, and conventional water-treatment
methods weren't designed to remove them.
Studies have found trace amounts of pesticides, pharmaceuticals,
and other substances in municipal water supplies.
Don't be worried thirsty, though. You can get clean water by using
water filters religiously. First, go to
consider the following three types of filters. Each has its pros and
cons, but combining two kinds of filters should get good results.
Reverse-osmosis unit: Using a semipermeable membrane
(which allows some molecules to pass through but not others), this
type of filter removes particles and molecules of dissolved
contaminants. Reverse osmosis can remove heavy metals,
bacteria, and viruses, and it may remove some pharmaceuticals.
However, it isn't effective for removing pesticides.
Distillation unit: This type of filtration system brings water to a boil,
then collects the steam and condenses it back into water, leaving
impurities (which need higher temperatures to boil) behind. Distillers
can remove heavy metals, bacteria, and viruses, but they can't
remove pesticides or pharmaceuticals.
Activated carbon filter: This type is the easiest to find and use.
It's available in faucet-mounted models, under-the-sink units,
and pitchers. Water flows through a carbon filter that attracts and
traps many impurities. The types of contaminants filtered vary by
brand, but all activated carbon filters remove chlorine, improve taste,
and reduce sediment. Most remove heavy metals and disinfection
by-products, and some remove parasites, pesticides, radon, and
volatile organic compounds (VOCs).
