National food policies in the Islamic Republic of Iran aimed at control and prevention of noncommunicable diseases

Background Diet plays an important role in the risk of noncommunicable diseases. In the Islamic Republic of Iran, national activities were started after release of the World Health Organization's (WHO) action plan on prevention and control of noncommunicable diseases. Aims This study describes national food policies implemented by the government in order to reduce noncommunicable diseases in the country in line with WHO action plan. Methods Newly adopted food standards and regulations linked to noncommunicable diseases from 2013 to 2018 were reviewed and the maximum permitted levels of salt and trans and saturated fats were compared in the old and new standards. Nutritional traffic light labelling to raise public awareness of healthy diets was evaluated. Results Fifteen food standards associated with eight food items that make up a large share of the daily Iranian food basket and three that make up a small share were evaluated. Policies on salt included reduction in maximum permitted percentage in bread, cheese and doogh (a fermented drink) to 1%, 3% and 0.8%, respectively. For trans and saturated fats, maximum permitted percentages were set as 2-5% and 30-65% of edible oils and fats, respectively. Nutritional traffic light labelling, which indicates the content of salt, sugar, fat and trans fat in foods, has been mandatory for all foods since 2016. Conclusions In view of the polices implemented to reduce the salt and fat/oil content of foods, significant decreases in noncommunicable diseases are expected in coming years in the country. However, further studies are needed to show the effectiveness of the interventions.
