Diet and asthma: vitamins and methyl donors
TLDR
In this paper, the authors show that insufficient evidence exists to recommend supplementation with any vitamin or nutrient acting as a methyl donor to prevent or treat asthma, and they conclude that a well-conducted randomised controlled trial (RCT) is the gold standard to establish whether diet has an effect on asthma.About:

Adiposity, Fractional Exhaled Nitric Oxide, and Asthma in U.S. Children
TL;DR: Among children with asthma, adiposity indicators are associated with worse asthma severity or control in those with high FeNO, and among children without asthma, BMI, PBF, and WC were associated with higher FEV1 and FVC, and lower FeV1/FVC.

TL;DR: The rise in prevalence of symptoms in many centres is concerning, but the absence of increases in prevalence in asthma symptoms for centres with existing high prevalence in the older age-group is reassuring.

TL;DR: The Committee concluded that the prevalence of vitamin D inadequacy in North America has been overestimated and urgent research and clinical priorities were identified, including reassessment of laboratory ranges for 25-hydroxyvitamin D, to avoid problems of both undertreatment and overtreatment.

Reciprocal TH17 and regulatory T cell differentiation mediated by retinoic acid.

TL;DR: The vitamin A metabolite retinoic acid is identified as a key regulator of TGF-β–dependent immune responses, capable of inhibiting the IL-6–driven induction of proinflammatory TH17 cells and promoting anti-inflammatory Treg cell differentiation, indicating that a common metabolite can regulate the balance between pro- and anti- inflammatory immunity.

TL;DR: It is shown that peripheral conversion of CD4+ T cells to T reg cells occurs primarily in gut-associated lymphoid tissue (GALT) after oral exposure to antigen and in a lymphopenic environment, and that the intestinal immune system has evolved a self-contained strategy to promote T reg cell neoconversion.
