“…12,13 Soft drinks are an important component of the Western lifestyle and diet. The intake of soft drinks in Australia has grown rapidly from around 47.3 L per person per year in 1969 to 113 L per person (both children and adults) in 1999.…”

Association between soft drink consumption and asthma and chronic obstructive pulmonary disease among adults in Australia

Background and objective: The aim of this study was to examine the association between soft drink consumption and self-reported doctor-diagnosed asthma and COPD among adults living in South Australia. Methods: Data were collected using a risk factor surveillance system. Each month a representative random sample of South Australians were selected from the electronic White Pages and interviews were conducted using computer-assisted telephone interviewing (CATI). Results: Among 16 907 participants aged 16 years and older, 11.4% reported daily soft drink consumption of more than half a litre. High levels of soft drink consumption were positively associated with asthma and COPD. Overall, 13.3% of participants with asthma and 15.6% of those with COPD reported consuming more than half a litre of soft drink per day. By multivariate analysis, after adjusting for socio-demographic and lifestyle factors, the odds ratio (OR) for asthma was 1.26 (95% confidence interval (CI): 1.01-1.58) and the OR for COPD was 1.79 (95% CI: 1.32-2.43), comparing those who consumed more than half a litre of soft drink per day with those who did not consume soft drinks. Conclusions: There was a positive association between consumption of soft drinks and asthma/ COPD among adults living in South Australia.

“…The conclusion that a higher intake of antioxidants might promote the development of allergic disease is certainly contrary to the prevailing antioxidant paradigm [88]. Earlier studies showed that frequent consumption of fruit and raw vegetables reduced the risk of asthmatic symptoms like wheezing [101].…”

“…This conclusion is further strengthened by the fact that cooking of such foods is able to prevent allergic responses as antioxidant compounds and vitamins are destroyed. A higher intake of β-carotene was also reported to be associated with a higher prevalence of rhinitis [88] and hay fever [89]. Reported side effects of food preservatives like sodium sulfite and benzoate comprise the possibility of allergic reactions.…”

A significant increase in the incidence of allergy and asthma has been observed during the past decades. The background of this phenomenon has not been well explained, but changes in lifestyle and habits are heavily discussed as contributing factors. Among these is a too clean environment, which may predispose individuals to increased sensitivity to allergic responses. Also the increase in dietary supplements including preservatives and colorants may contribute to this. In vitro, we and others have shown in freshly isolated human peripheral blood mononuclear cells that antioxidant compounds like vitamins C and E as well as food preservatives and colorants exert significant suppressive effects on the Th1 immune activation cascade. The effects observed may be based on the interaction of antioxidant compounds with proinflammatory cascades involving important signal transduction elements such as nuclear factor-ĸB. Although only obtained in vitro, these results show an anti-inflammatory property of compounds which could shift the Th1-Th2-type immune balance towards Th2-type immunity. This review article discusses the potential role of increased use of antioxidant food supplements as well as preservatives and colorants in the increase in allergy and asthma in the Western world.

“…9,10,12 Others have inconclusive results as far as the role of dietary pattern in asthma prevention and treatment is concerned. 14,16 Although there have been numerous studies more population based study are required to established the association asthma, allergy and diet. However on a larger perspective, we can look at the diets of people and its effect on asthma by dividing them into lacto ovo vegetarian and non-vegetarians.…”

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.

Dietary patterns and adult asthma: population‐based case–control study

Abstract: Overall there were no clear relations between dietary patterns and adult asthma; associations in nonsupplement users and whites require confirmation. The finding for chronic bronchitis was unexpected and also requires replication.
