In the last decades Western countries have witnessed an increase in allergic diseases like hay fever and asthma [1], [2] although very recent results suggest a flattening of rising asthma incidence in affluent societies [3], [4]. Because dietary factors like intake of antioxidants changed during the same period, it has been postulated that they might influence the development of allergic diseases [5], [6], [7]. Additionally there is evidence that allergic diseases are mediated by oxidative stress, which means an imbalance between reactive oxygen and nitrogen species and antioxidants [8]. Carotenoids, vitamin E, and vitamin C act as non-enzymatical antioxidants. Additionally, vitamin E is thought to act by inhibition of IgE production and membrane stabilisation [9], [10] vitamin C by inhibition of specific prostaglandin synthesis [7], [9]. In this study we focus on the contribution of carotenoids, tocopherols and vitamin C in plasma to allergic rhinitis and allergic sensitization and use the concentration of these micronutrients in plasma as a marker of intake, absorption and subsequent metabolism.

Materials and Methods

In this study we estimated the plasma concentration of six carotenoids, α- and γ-tocopherol and vitamin C as biomarkers of intake, absorption and subsequent metabolism of these nutrients. Their association with allergic rhinitis and sensitization was assessed by means of unconditional logistic regression models. Data from a cross-sectional study on representative data of dietary and lifestyle habits of the population of Bavaria, Germany, were analyzed. Measurement of the six carotenoids α-carotene, β-carotene, lycopene, lutein/zeaxanthin, canthaxanthin, cryptoxanthin, as well as of α-tocopherol, γ-tocopherol and vitamin C were performed in the plasma samples of 547 adults between 19 and 81 years of age. Participants with specific IgE ≥ 0.7 kU/l in serum were categorized as sensitized.


We observed a negative association between total plasma carotenoids and the prevalence of allergic rhinitis (p for trend=0.0332); results for lycopene failed to reach statistical significance (p=0.0608). Other single carotenoids, tocopherols or vitamin C were unrelated to allergic rhinitis. Allergic sensitization was negatively associated with plasma γ-tocopherol (p for trend=0.0410). No other antioxidant was significantly related to allergic sensitization.


Our finding of a negative association between sum of six measured carotenoids and allergic rhinitis suggests that a high intake of various fruit and vegetables might reduce the risk for allergic diseases. The results of a negative association between γ-tocopherol, but not α-tocopherol in plasma might be a sign for a different role of these two tocopherols in allergic sensitization. It would be interesting to investigate the two tocopherols separately in future studies, especially in countries with high dietary intake of γ-tocopherol.
