Are your asthma patients missing out on the
nutrients they need?
Asthma reactions to dairy foods are unlikely.1 - 4
Food is not commonly a problem in asthma. Controlled studies
indicate that less than 5% of all people with asthma have an attack
because of certain foods.5 Patients probably do not need to give up
any foods unless they have a proven allergy.
Study finds no link between dairy foods and bronchoconstriction
in the absence of recognised food allergy.1
A
randomised, placebo-controlled, double-blind, crossover trial
enrolled 20 patients with asthma, 10 of whom believed that dairy
foods exacerbated their asthma and 10 who did not. Symptoms and
spirometry results were recorded before and after challenge with
milk or placebo, representing both objective and subjective
evaluation. The results:
- No subject reported an increase in cough or sputum
production following dairy challenge.
- Symptom scores showed no statistically significant
differences in outcomes of dairy and placebo challenges.
The authors concluded that they could not demonstrate that dairy
foods induce bronchoconstriction. They recommended that health care
professionals ensure their patients are not unnecessarily risking
nutritional deficiencies by restricting their dairy consumption.
Study finds dairy foods do not stimulate mucus production.4
In a prospective study to determine the effect of dairy foods on
mucus production, data were assessed on 51 volunteers aged 18-35
infected with the common cold virus. Their response to dairy foods
was evaluated by both objective and subjective means. The authors
found:
- No increase in mean nasal secretion with milk intake.
- No delayed effect following milk consumption.
- No association between milk intake and cough, nose
symptoms or congestion.
Overall, the authors concluded that no statistically significant
association can be detected between dairy foods and mucus
production.
Patients
risk health by limiting dairy food.
- Calcium deficiency has been demonstrated in children due to
dietary modification.1
"...many people with asthma may
be unnecessarily depriving themselves of a rich and important source
of nutrients, a situation that could lead to malnutrition and
osteoporosis."1
Dairy foods are a primary source of essential nutrients in
both adults and young children...
3 serves of dairy foods provide*:
- 110% of calcium
- 50% of protein
- 45% of vitamin A
- 95% of vitamin B12
- 75% of riboflavin.
*based on the RDI for an adult male
National Asthma Council recommends dairy foods as part of a
healthy, well-balanced diet.
- Rich in calcium, protein, vitamin A, vitamin B12,
riboflavin.
- No demonstrated association with bronchoconstriction.
- No demonstrated increase in cough or sputum production.
Dairy. Every day for life.
