Vitamin
Therapy & Asthma
Apart from the importance of
diet in our general health and well-being, research is now confirming that specific
nutrients and dietary practices are very much associated with asthma. For instance, a lack
of vitamin A in babies has been shown to be related to increased susceptibility to
bronchial problems(1).

Vitamin
C
& Asthma
According to researchers
at the Pediatric Ambulatory Clinic, Rabin Medical centre, Vitamin C offers a
protective effect for asthma sufferers who experience exercise-induced
hyperactive airways.
20 asthma patients ( 13 men, 7 women) aged between
7-28 years and diagnosed with exercise-induced asthma, participated in the
study. All of the patients underwent pulmonary tests and were then randomly
assigned to receive 2g vitamin C or a placebo tablet. one hour before a
7-minute exercise on a treadmill. One week, later the same experiment was
conducted, but this time the patient groups were reversed.
Whilst the vitamin C did not show pulmonary function
tests at rest one hour after the exercise, nine of the patients experienced
a protective effect after taking the vitamin C. Interestingly, the same
protective effect was seen when the patients took only 0.5g vitamin C.

Cigarette Smoke & vitamin C
& Asthma
Smokers and passive smokers (ie. those in regular close proximity to someone smoking) are
more prone to suffer asthma and other respiratory disorders due to the damage caused by
the smoke. It is crucial for asthma sufferers, especially young children whose bodies are
still developing, to be allowed to breathe smoke-free air. They have enough to contend
with the traffic and gas fumes.
A report by the National Children's Bureau in March 1993(5) stated: "children are hit
harder by pollution because they are smaller, still developing and physiologically
immature. Generally their bodies are quicker to absorb toxic substances and slower to
eliminate them. Children are therefore badly affected by contaminated air...The well-being
of children in the UK is adversely affected by environmental factors which harm their
health or stunt their development."
According to Professor Danial Menzel of the Department of Community & Environmental
Medicine, University of California, "The slow, long-term effects of continuing
exposure to air pollution on the development of the lung also suggests that children
should be provided with protection by supplementation." Foods that are rich in
vitamin C are blackcurrants, strawberries, citrus fruits, kiwi fruits, watercress, mustard
and cress, green peppers, raw cabbage, cauliflower, spinach and parsley.

Vitamin
B6 (pyridoxine)
& Asthma
Vitamin B6 has been shown in clinical studies to be of great benefit to asthma sufferers.
In one report (6) a double-blind study was carried out with 76 asthmatic children between
the ages of 2 and 16 by a team of 5 doctors headed by Platon J Collipp MD, chief of the
Department of Pediatrics at the Nassau County Medical Centre New York.
The children were divided into 2 groups, one group being given 100mg of vitamin B6 twice
daily and the other group were given placebo (dummy) tablets. After only one month the
results showed that the vitamin B group had experienced fewer asthmatic attacks than the
other children with less wheezing, coughing, tightness or breathing difficulties. As a
result, they required less medication than the other children. After five months the
improvements in the vitamin B6 group were even more dramatic and Dr Collipp concluded that
Vitamin B6 "reduces the severity of asthma in many, but not all, asthmatic
children". There were no side effects from vitamin B6 but as with all vitamin
supplements we suggest that you consult a qualified health practitioner before taking any
supplements.

Avoid
Mucous-forming foods
& Asthma
All mucous-forming foods such as dairy foods, chocolates, refined white flour bread ,
cakes, and white sugar are considered by naturopaths to be best avoided for all
respiratory conditions and especially asthma. This is because excess mucous only serves to
further block the airways and thus aggravate the condition.

Avoid
Salt
& Asthma
It is interesting to note that the incidence of asthma deaths is far lower in those
countries where salt is not used in copious amounts. Even in England and Wales, the
incidence of asthma has been shown to be related to consumption of salt. Recent studies
have confirmed that salt is indeed related to asthma. One research project (7) in
Leicester revealed that asthmatic patients given a low sodium diet for three months
experienced improved lung function and needed fewer drugs but once they started eating
more salt again, the good effects disappeared.

Ionisers, Air purifiers & Household plants
& Asthma
Air pollutants are becoming increasingly relevant and are even
considered major causes of asthma. Apart from campaigning for better quality air, there
are various ways of cleaning the air at home and even in the car which can be of very
great benefit to people suffering from asthma.
Air Purifiers - Conventional air purifiers use a small fan to draw in contaminated air
(dust, pollen, smoke, etc) which is then filtered. These tend to be expensive.
Ionisers - Ionisers are an inexpensive way of providing fresher and cleaner air in the
home. As their name suggests, they create negative 'ions' in the air which have a tonic
effect on the nervous system. Negative ions are produced in anture and are found in
abundance in mountain tops, near waterfalls, oceans and after a thunderstorm shower. The
ioniser gives a negative charge to airborne particles which is thought to make people feel
better. However, more significantly for asthma sufferers, ionisers also remove dust
particles, smoke, pollen and smells from the air.
There are some models which can be used in cars as well as indoors.
They are relatively
inexpensive (approximately £30 upwards) and cheap to run but they can cause staining of
nearby surfaces as particles are drawn to the ioniser tend to stick to the surrounding
walls.
Household Plants - Certain household plants can 'filter' the air very efficiently! A two
year study by NASA scientists revealed that common household plants such as English Ivy
(Hedera helix) , indoor chrysanthemums and spider plants can remove a number of dangerous
environmental toxins from the air including formaldehyde and benzene (both known
cancer-causing agents).

Milk
The health of 2187 children was monitored for six years.
After allowing for all confounding factors, this Australian study found that
children given milk other than breast milk before the age of four months
have a 25%-35% increased risk of developing asthma and related breathing
difficulties.
