Asthma Patients Should Avoid

Asthma patients, please note — high-fat meals are a strict no-no for you, say scientists. A new study has revealed that people with asthma who consume a high-fat, high-calorie meal can show an increased airway inflammation just hours after the binge, and the food can inhibit the response to the medication for the condition.
Lead scientist Lisa Wood of Newcastle University said: “This is the first study to show that a high fat meal increases airway inflammation, so this is a very important finding.” The scientists have based their findings on an analysis of 40 asthma patients who were randomised to receive either a high-fat, high-calorie food, consisting of fast food burgers and hash browns containing about 1,000 calories, or a low-fat, low-calorie diet.
They found that the subjects who had consumed the high-fat meal had a marked increase in airway neutrophils and TLR4 mRNA gene expression, the ‘Health and Medicine’ journal reported in its latest edition. TLR4 is a cell surface receptor that is activated by nutritional fatty acids — TLR4 “senses” the presence of saturated fatty acids, and prompts the cell to respond to the fatty acids as if they were an invading pathogen, releasing inflammatory mediators.
While the study didn’t definitively distinguish between high fat and high energy the increase in TLR4 activity suggests that dietary fat is important to the effects, say the scientists. Subjects who had consumed the high fat meal also had reduced bronchodilator response as compared to those who had consumed the low-fat meal.
Dr Wood said: “Subjects who had consumed the high-fat meal had an increase in airway neutrophils and TLR4 mRNA gene expression from sputum cells, that didn’t occur following the low fat meal. “The high fat meal impaired the asthmatic response to albuterol. In subjects who had consumed a high fat meal, the post-albuterol improvement in lung function at three and four hours was suppressed.
“The observation that a high fat meal changes the asthmatic response to albuterol was unexpected as we hadn’t considered the possibility that this would occur. If these results can be confirmed by further research, this suggests that strategies aimed at reducing dietary fat intake may be useful in managing asthma.”



Daily Precautions for Asthma Patients

Asthma is a chronic disease of the respiratory system and may turn even fatal at
times. It is therefore important for the asthma patients to take proper care and
precautions regularly. Asthma patients suffer from attacks that enforce the system to
breathe with difficulty. Wheezing, choking, gasping for breath and suffocation are the
symptoms of asthmatic attack. The attacks may last up to several minutes and leave a
person thoroughly exhausted. There can be severe organ damage due to problem in
respiration during the asthma attack. Also the system may suffer from lack of oxygen for
a longer duration of time. It is therefore imperative to exercise proper caution and avoid
the onset of an attack to the extent possible.
Some easily followed precautions everyday may keep an asthmatic without
suffering an attack.

These precautions are:

· An asthmatic needs to follow routines. This is because it is generally seen that
people do not suffer the agony of an asthmatic attack if they continue to live their
life in a regular way. The problem arises mainly when the people go out of their
way and break all the routines. The system thus gets unnecessarily pressured
and reacts badly by manifesting the symptoms of the disease in the oddest of
ways and without many warning signs. Sometimes the body does give the
warning signs but the person may ignore them completely.

· Daily morning walk does wonders to the system. But in the case of asthma
patients the benefit from early morning exercise is enhanced manifold. This is
because the early morning is the time when the air is pure and at its best.
Exercising the lungs with the early morning air does wonders to the asthmatic
lungs and respiratory tract.

· Daily morning exercise schedule needs to be followed religiously in case of an
asthma patient. Not only does this help in exercising the whole system but it also
makes a person live a more disciplined and regularised life. This is because if a
person gets into the habit of getting up early, in all probability he would try and
sleep early too and his routine will automatically be set and fixed.

· The daily diet of an asthma patient should be kept simple and nutritious. He
should take care of not eating heavy meals as they would tax the system
unnecessarily. Care should be taken to keep the meals small and frequent if
need be, rather than consuming standard heavy meals at set hours. Also the
food should be cooked with less oil and spices to keep it easily digestible. The
diet should be mainly vegetarian with less of fats and carbohydrates. Sweets
should best be avoided at night time. Dinner should be consumed at least two
hours before sleeping so that the stomach is almost empty before sleeping.
Dietary intake of fruits and vegetables should be enhanced. Snacks should be
mainly in the form of fresh fruits and vegetables only and fatty, oily and salty or
sweet snacks should be avoided completely.

· Asthma patients should avoid smoking completely. Smoking fills the system with
many toxins and the respiratory system gets flooded with them. These toxins are
major irritants to the respiratory tract and create an undue pressure on the
system that may be too much for an asthmatic to handle. An asthmatic may get
more bronchial spasms and is more likely to be affected with respiratory
infections if he continues to smoke.

· An asthmatic person should also not indulge in drinking too much. This is
because drinking causes a person to lose sense and become more prone to
breaking disciplines of routine and diets. An asthmatic may become careless with
his diet and may tend to overeat to counteract the influence of alcohol if he
indulges in drinking too much.

· Asthma patient’s surroundings should be kept neat and tidy. As far as possible
clutter should be completely avoided to steer clear of dust induced allergies that
may create an attack. Clutter in the surroundings inhabits several mites and
allergy causing organisms. It is therefore necessary that the furniture and other
stuff should be arranged in such a way, which allows proper dusting and cleaning
on a daily basis.

· Asthma patients may have difficulty with the atmospheric pollution also. It is very
important to assess whether the patient may be allergic to any particular kind of
allergen present in the atmosphere around his place of dwelling or occupation.
Sometimes certain professions support the excessive usage of one kind of toxin
or the other, in which case a change in profession or occupational conditions
may remain to be the only option.

· Asthmatics should also be very careful of not getting mentally excited too much.
This is because the mental aggravation may lead to appearance of asthmatic
symptoms in patients. On a daily basis it is better not to accumulate taking
decisions, whether in the personal life or in the professional life. The work should
also be handled as far as possible on a daily basis to avoid excess stress and
anxiety.

· In order to manage asthma it is very necessary to accept the disease and the
limitations attached with it in one’s daily life. If proper discipline is maintained a
patient can have a long and problem free life.
