How Second Hand Smoke Threatens Your Health

by: Alex Fir

Secondhand smoking, breathing in of environmental tobacco smoke (ETS), is also called passive smoking. It is when a person breathes in smoke given off into the environment by other people.

Secondhand smoke or ETS is a combination of side stream smoke coming straight from the burning tobacco and the mainstream smoke that is exhaled by the smoker. It comprises of over 4000 chemical constituents, a large proportion of which are the inducers of respiratory illnesses and around 40 are known or suspected carcinogens.

The US Environmental Protection Agency (EPA) has classified ETS as a class A (known human) carcinogen along with other known carcinogens such as arsenic, asbestos and benzene etc.

ETS is unfiltered, thus the levels of carcinogens in it are much more than in smoke inhaled directly by an active smoker. Smoking of a cigarette produces smoke from two major places, mainly from the tip of cigarette and from the rest of the cigarette as the hot vapors liberated through the cigarette and its filter.

About 70% to 80 % of ETS is from the burning tip of cigarette and comprises of the highest levels of nicotine, carbon monoxide, tar and various other carcinogens. Therefore, a constant exposure to an ETS is apparently even more injurious than directly smoking a cigarette for an equivalent period.

Effects of Exposure to Secondhand Smoke

Immediate effects:

Immediate effects of secondhand smoking comprise of eye irritation, cough, sore throat, headache, nausea and dizziness.

Long-term effects:

Lung cancer: The major cause of lung cancer among non-smokers is secondhand smoke. One of the studies revealed that hospitality workers who were exposed to secondhand smoke became three times more prone to lung cancer.

Cardiovascular problems: ETS can induce short-term and long-term harm to the heart by decreasing its functional capacity and lowering the capacity of blood to carry oxygen. Some of the chemicals in secondhand smoke can block or harden the arteries, causing problems like atherosclerosis, hypertension and later heart attack. In one of the studies, it was found that secondhand smoking enhances the risk of a heart attack by at least two times.

Stroke: Non-smokers exposed to secondhand smoke run at least 80% more risk of stroke than do the non-exposed people.

Asthma: One of the studies revealed that the non-smokers exposed to ETS at work showed at least twice the risk of asthma than the non-exposed people did. Those who were exposed to ETS at home as well, showed as much as five times greater risk for asthma than the non-exposed people did. In individuals who already suffer from asthma, exposure to ETS can
significantly decline their lung function.

Breast Cancer: Some of the recent studies have revealed ETS to increase the risk of breast cancer among women.

Effects on the fetus:

Smoking by a pregnant woman can have various serious consequences on the developing fetus.

� Babies born to women who smoked during their pregnancy have a low birth weight and are often born prematurely.

� Their organs, chiefly the lungs, are smaller than of other babies and these babies are more susceptible to cot death.

� They are more prone to illness all their life and are more likely to become addicted to the tobacco later in their life.

Effect on Children

� Kids that are exposed to secondhand smoke from either parent during the first year of their lives are far more likely to be afflicted with asthma, pneumonia, bronchitis, bronchiolitis and other respiratory problems than kids who were not exposed.

� Secondhand smoking may also predispose children to the impairment of the blood circulatory system, behavioral problems and olfactory (nasal) problems.

� It also increases their susceptibility to develop cancer during their adulthood.

Cancer Diet - Minerals
by: Marilyn Bennett

A cancer diet needs a good balance of minerals because minerals are needed by all cells for proper function. Patients are often found to be mineral deficient, so this is an area of the diet that needs particular attention.

There are two classes of minerals. Macrominerals, such as the well known calcium, magnesium, sodium, potassium and phosphorus, and microminerals, such as boron, chromium, copper, iron, iodine, germanium, sulfur, silicon, vanadium, zinc, manganese and molybdenum.

The good news is we will get most of the minerals we need, provided we are eating a diet based on a wide variety of fruits and veggies, with the addition of nuts, seeds and grains.

Where we can get in to trouble is that minerals are washed out of soils with constant rain, and modern fertilizers don't usually contain the wide variety of minerals we need. Organic gardeners usually use rock minerals on their soils and this results in organic produce have a much higher and broader range of minerals.

Germanium is one micromineral that cancer patients are often low on. It is essential for immune function and is critical to tissue oxygenation. Cancer grows rapidly where there is low oxygenation of cells. Germanium is found in broccoli, celery, garlic, onions, rhubarb, sauerkraut and tomato juice as well as aloevera and ginseng.

Iodine deficiency has been linked to breast cancer in more than one study. Seasalt contains iodine and a variety of minerals rather than the isolated highly processed iodine additive in table salt. Asparagus, garlic, lima beans, soybeans, sesame seeds all contain natural iodine along with the nutrients needed for good absorption.

Large amounts of brassicas eg brussels sprouts, cabbage and cauliflower, along with peaches, pears and spinach can block absorption of iodine, so ensure there is a balance of iodine rich foods in your diet.

Selenium has been linked to cancer. Selenium and Vitamin E work together to attack free radicals. Selenium is critical for pancreatic function, and pancreatic enzymes are critical to the bodies ability to fight tumour activity. This mineral is generally found in meat and grains, however countries such as New Zealand and much of America is known to have selenium deficient soils.

As there have been several studies showing that good selenium levels have significantly reduced the risk of cancer, this is one mineral you want to have enough of.

Food sources that should be included frequently in a cancer diet are: brazil nuts, broccoli, brown rice, brewers yeast, chicken, kelp, onions, salmon, seafood, tuna, wheatgerm and whole grains. Garlic, chamomile, ginseng and parsley are all easy to use concentrated forms that can be added to the diet daily.

A couple of warnings:

Be very careful about self-dosing with minerals as several of them will block absorption of others if the dose is too high.

Again, eating a variety of foods, with particular notice taken of those that have high mineral levels is the safest way to go. If you wish to explore mineral supplementation further, talk to your naturopath or nutritionist. But whatever you do, don't ignore the importance of these vital elements to your well being.
