The increasing prevalence of food allergies in developed and developing countries has raised many questions about that in scientific societies. This prevalence made researchers eager to understand the steps taken to prevent food allergies in children. Children's food allergies are often thought to be the result of exposure to allergens during pregnancy, lactation, and nutrient deficiencies such as vitamin D. in this review, we collected and reviewed new studies about nutritional strategies to prevent food allergies in children. Studies have shown that eliminating food from the mother's diet during pregnancy and lactation is not recommended. Also, despite the many benefits of exclusive breastfeeding for infancy, there is still limited evidence to support food allergy prevention with breastfeeding. Introducing solid foods at 4-6 months of age may reduce the risk of developing allergies in children; therefore, it is not suggested to delay the introduction of food. Also, introducing peanuts and boiled eggs earlier than 12 months of age can reduce the risk of some allergies. There is little evidence to support using a hydrolyzed formula and vitamin D supplement to prevent food allergies. Nutritional interventions to prevent food allergies still have many ambiguous questions; however, it can be said that avoidance of allergenic foods is not suggested, and exposure to foods can induce tolerance.

Acid-base status, which can be affected by dietary acid load, has been related to risk factors for metabolic syndrome (MetS). In the current study, we investigated the association between dietary acid load and metabolic syndrome among children and adolescents. This cross-sectional study was conducted on 500 participants, aged 8-18 years old. The dietary intake of participants was assessed using a validated semi-quantitative food frequency questionnaire, and the potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores were calculated. Multiple logistic regression models were used to estimate the risk of metabolic syndrome according to the PRAL and NEAP quartile categories. The mean age of the participants was 12.9±2.5 years old. Mean PRAL and NEAP scores were -4.23 and -19.70 mEq/day, respectively. In this study, the potential confounders including age, sex, BMI, and total energy, were adjusted in the multivariable-adjusted model. By using logistic regression, no significant association was observed between PEAL and NEAP with metabolic syndrome (OR= 0.98, 95% CI: 0.55-1.55, p-value=0.775 and OR=0.88, 95% CI: 0.49-1.39, p-value=0.418, respectively), after adjustment for potential confounders. Longitudinal studies should be conducted to evaluate the association between PRAL and NEAP with metabolic syndrome in children.

Children in elementary school ages due to entering the new era of their life are more high risk of facing with wrong food habits that have been associated with noncommunicable diseases. This study was conducted to assess obesity/overweight status and lifestyle behavior (diet, physical activity and screen time) in 7-12 years children in Buin-Zahra health network. The data of 120 children from “SIB system” was collected in January 2018 as a cross-sectional study. It consisted of weight, height, amount of fruits, vegetables, dairy products, and junk foods intake, physical activity and screen time. Z-score for height for age (HAZ), body mass index for age (BAZ) and weight for age (WAZ) were calculated using World Health Organization reference data. Anthropometric assessments revealed obesity (BAZ>2) in 6.6%, thinness (BAZ<-2) in 13.3% and stunting (HAZ<-2) in 4.1% of children. Stunting and thinness were significantly more common in males. Fruit, vegetable and dairy products intake and screen time were more in females. A strong positive correlation between screen time and age was significant at the 0.01 level. There are substantial rates of stunting, thinness, and obesity in 7-12 years children. The results suggest the need for evaluating health caregivers’ educational methods to improve nutritional status in children.
