Detoxification
The body must continually rid itself of toxic substances, which derive from a
range of sources. From the atmosphere and from the food chain we ingest a range
of toxins, from heavy metals such as mercury, to pestices, food additives and
drugs. The body produces its own toxins as natural by-products, which would
cause problems if allowed to accumulate. A further potential source of toxicity
is infectious micro-organisms.
The load on the body's detoxification systems is greater than ever before.
The Liver
The liver is the body's main detoxification system. It biochemically transforms
toxins and waste products, preparing them for excretion, either via the kidneys
(which produce urine) or the digestive tract.
Signs of poor liver function include headaches and migraines, itchy
or watery eyes, a stuffy nose, muscle or joint pains, skin problems and general
fatigue. But we need to be careful as liver problems are not always apparent
until significant harm has occurred.
Free Radicals and Antioxidants
Free radicals are highly reactive molecules which cause damage by reacting
chemically (or oxidising) other molecules such as DNA and proteins. Free
radicals are created naturally in cellular processes, but they also derive from
external pollution.
Antioxidants are substances that protect against this oxidative stress by mopping
up and disarming free radicals. We need a range of antioxidants, some of which
are produced by the body, but a complete defence requires important nutrients in
the diet. Antioxidants are needed in high levels in the liver and brain.
