An inverse association was<br />

observed in analyses based<br />

on age at introduction of<br />

fish. Children introduced<br />

to fish between 3-8 mo of<br />

age had a reduced risk <strong>for</strong><br />

asthma OR 0.73 (95% CI<br />

0.55–0.97), eczema (OR<br />

0.77, 0.64–0.92), allergic<br />

rhinitis (OR 0.77, 0.60–<br />

0.97), and sensitization to<br />

food and airborne allergens<br />

(OR 0.78, 0.64–0.95) at<br />

age 4 yrs compared with<br />

children introduced to fish<br />

at 9 mo or older. Fish<br />

consumption of 2-3 times<br />

per month at age 12 mo is<br />

associated with reduced<br />

risk of allergy at age 4 yrs:<br />

Asthma OR 0.82 (0.54-<br />

1.29), eczema OR 0.71<br />

(0.53-0.95), allergic<br />

rhinitis OR 0.51 (0.35-<br />

0.73), at least one allergic<br />

Delaying initial exposure to<br />

cereal grains until after 6<br />

mo significantly increase<br />

the risk of developing wheat<br />

allergy at mean age of<br />

4.7yrs (OR: 3.8, 95% CI<br />

(1.18-12.28)), after<br />

adjusting <strong>for</strong> breastfeeding<br />

duration, introduction of<br />

rice cereal, family history of<br />

allergy, and history of food<br />

allergy be<strong>for</strong>e 6 mo of age.<br />

The timing of rice-cereal<br />

introduction was not<br />

significantly associated with<br />

wheat allergy after<br />

adjustment <strong>for</strong> cereal-grain<br />

exposure, breastfeeding<br />

duration, and family history<br />

of allergy.<br />

No specific data was reported<br />

on association with delayed<br />

introduction of solids and risk<br />

of asthma or atopy.<br />

Evidence of a link between<br />

the early introduction o solid<br />

foods in general and the<br />

onset of atopy is conflicting<br />

and inconsistent. Evidence<br />

as to an optimal time <strong>for</strong> the<br />

introduction of any<br />

individual solid food in the<br />

infant’s diet is lacking. The<br />

introduction of solid foods is<br />

not an ideal research end<br />

point because its full benefit<br />

depends on the duration of<br />

breastfeeding. But, authors<br />

recommend: (1) Exclusion<br />

of supplemental foods is<br />

indicated during the first 6<br />

months of life because if has<br />

a preventative effect against<br />

the onset of allergic<br />

symptoms. (2) The<br />

introduction of supplemental<br />

foods during the first 4<br />

months of life has been<br />

associated with a higher risk<br />
