“…A study of Chinese Singaporeans found that a diet rich in meats, Na and refined carbohydrates was positively associated with habitual cough and phlegm (7) , while a study of Japanese female students found that a butter and rapeseed oil dietary pattern, and a fast-food, soft drink and juice dietary pattern were both positively associated with wheeze (8) . In France, a study of female teachers found that a pastry, processed meat and dessert pattern was positively associated with reporting frequent asthma attacks, and a nut and wine pattern was negatively associated (9) . One problem with the PCA approach is that it does not lend itself well to the synthesis of evidence from different studies.…”

Dietary patterns offer an alternative to the analysis of individual foods or nutrients in nutritional epidemiological studies. The aim of the present study was to identify dietary patterns common to different European countries and examine their associations with asthma. In five study centres (two in Germany, two in the UK and one in Norway), 1174 adults aged 29–55 years completed a FFQ and respiratory symptoms questionnaire. A meta-analytic approach was used to identify the dietary patterns and analyse them in relation to current asthma, asthma symptoms and bronchial responsiveness (BHR). Two patterns emerged, generally correlating with the same foods at different centres: one associated with intake of meats and potatoes; the other with fish, fruits and vegetables. There was no evidence that the fish, fruits and vegetables pattern was associated with asthma (OR 1·11 (95 % CI 0·93, 1·33)), symptom score (ratio of means 1·07 (0·98, 1·17)) or BHR (regression coefficient − 0·01 ( − 0·12, 0·10)), though these CI appeared to rule out large protective effects of consuming these foods. There was no overall evidence that the meat and potato pattern was associated with asthma (OR 1·02 (0·79, 1·31)), symptom score (ratio of means 1·07 (0·84, 1·36)) or BHR (regression coefficient − 0·08 ( − 0·27, 0·10)), but there was heterogeneity between centres in the association with symptom score: a negative association at the two German centres; a positive association at the others. Heterogeneity in a multi-centre observational study of diet could suggest alternative explanations for apparent effects of diet, such as uncontrolled confounding.

“…Briefly, food items were grouped a priori into 56 separate food groups and, as previously described [9], three dietary patterns were obtained from these food groups: a ''prudent'' pattern (high intake of fruit and vegetables), a ''Western'' pattern (high intake of pizza/salty pies, desserts, cured meats and pasta) and a ''nuts and wine'' pattern (high intake of nuts and seeds, salty biscuits, olives, wine and fortified wine) [9]. Each dietary pattern score was categorised into tertiles (tertile 1: the lowest score; tertile 3: the highest score).…”

“…The overall prevalence of childhood asthma was 1.6% and of adult-onset asthma, 3.2%. Frequent asthma attacks were defined by a report of one or more attack per week in the last 12 months [9]. As the study was carried out by postal questionnaire, there was no lung function test.…”

The decrease in the number of children living on traditional farms in France during early childhood and changes in diet could both play a role in the increase in asthma prevalence over the last decades. This study aimed to assess 1) the association of farming lifestyle in childhood and asthma, and 2) whether diet in adulthood modifies the association between farming lifestyle in childhood and adult-onset asthma.In the French Etude Epidemiologique des Femmes de la Mutuelle Générale de l'Education Nationale (E3N) study (54,018 females; age 43-68 yrs), three indicators of farming lifestyle were defined: one using individual data (having farmer parents) and two using ecological data (born in a rural area and exposure to cattle).All farming lifestyle indicators were related to childhood-(,16 yrs) and adult-onset asthma (OR (95% CI) values for farmer parents were 0.54 (0.42-0.70) and 0.72 (0.62-0.84), respectively), and to diet in adulthood, in particular to high fruit and low wine intakes. The association between farmer parents and adult-onset asthma was not modified by diet in adulthood.Results extend previous observations in younger cohorts on the protective role of contact with livestock and farming lifestyle on asthma, in particular during childhood.

Background: Asthma is an increasing global health burden, especially in the western world but now a day not uncommon in developing countries like India. With rapid changes in diet being one of the hallmarks of westernization, nutrition may play a key role in affecting the complex genetics and developmental pathophysiology of asthma. People consume a combination of foods from various groups that form a dietary pattern. Studying the role of dietary patterns in asthma is an important emerging area of research. The aim of this study was to review dietary patterns and asthma outcomes in children, also to maternal diet and child asthma. With all the studies that have been undertaken, some clearly state the protective effects/adverse effects of certain foods, while others deepen the dilemma. The objective of this study was to establish association between dietary habits and Asthma (and allergic disorders) in children. Methods: A questionnaire obtained from the International study for Asthma and Allergy in Children questionnaire was used to evaluate the dietary habits and disease status of the 834 children attending to pediatrics OPD/IPD for varying disease condition of eastern Odisha region over a period of 2 years. Children aged 4 to14 years with diagnosis of asthma were eligible for the study. The clinical criteria for diagnosis of asthma were based on the recommendations of the British Thoracic Society Guidelines, October 2014. The diagnosis of asthma was made if all the following criteria were met: (i) recurrent episodes (>3) of one or more of the following symptoms -wheeze, cough, breathing difficulties and chest tightness, particularly at night or in the early hours of the morning; (ii) respiratory symptoms improve spontaneously or after treatment (bronchodilators with or without corticosteroids); (iii) presence of triggers or aggravating factors such as exposure to allergens or irritants, physical exercise, weather changes or emotional stress; and (iv) personal history of atopy (allergic rhinitis or eczema) and/or family history of atopy (asthma, allergic rhinitis or eczema) in first-degree relatives. The children/ parental had to fill the questionnaire under teachers' guidance. Results: Present study reveals asthma and allergic disorders were more prevalent in those consuming a lacto ovo vegetarian diet. Other significant association was seen with Junk food {significantly correlated (OR: 1.643, P <0.005)}, positive family history (P < 0.005) and as well as with obesity (P < 0.005). Conclusions: Although it is common belief that vegetarians are less affected by asthma and other allergic disorder which is backed up by numerous previous studies which reveals a vegetarian diet to be protective against asthma. But our study shows a different picture. The school of thought that considers vegetarian diet tobe protective may lay its basis on the high antioxidant levels in the blood, which according to a new hypothesis, on the contrary may be related to increased risk of allergies too.
