Food fortification is increasingly recognized as an effective approach to improve a population's micronutrient status. The present report provides a critical review of the scientific evidence currently available on the impact of zinc fortification on zinc nutrition. The available studies clearly show that zinc fortification can increase dietary zinc intake and total daily zinc absorption. Most absorption studies also indicate that adding zinc to food does not adversely affect the absorption of… Expand
Zinc Fortification of Cereal Flours: Current Recommendations and Research Needs
TLDR
Zinc fortification of cereal flour is a safe and appropriate strategy for enhancing the zinc status of population subgroups who consume adequate amounts of fortified cereal flour, although additional information is needed to confirm the efficacy and effectiveness of large-scale zinc fortification programs to control zinc deficiency. Expand
Effects of Foods Fortified with Zinc, Alone or Cofortified with Multiple Micronutrients, on Health and Functional Outcomes: A Systematic Review and Meta-Analysis
TLDR
It is found that zinc fortification with or without MMN reduced the prevalence of zinc deficiency and may provide health and functional benefits, including a reduced incidence of diarrhea. Expand
Systematic Review of Zinc Fortification Trials
TLDR
Although the findings highlight that zinc fortification is associated with an increased serum concentration of the micronutrient, overall evidence of the effectiveness of this approach is limited and large-scale fortification programs with robust impact assessment should be initiated to cover larger populations in all age groups. Expand
Food fortification with zinc seems to be an attractive public health strategy and a number of programs
Zinc is one of the essential trace elements required by the human body as it is present in more than a hundred specific enzymes and serves as an important structural ion in transcription factors.Expand

TLDR
Recent findings that Zn bioavailability from high-phytate, whole-day diets is lower than previous estimates suggest that revision of Zn estimated average requirement for LIC may be warranted. Expand
Plasma zinc concentration responds to short-term zinc supplementation, but not zinc fortification, in young children in Senegal1,2.
TLDR
Plasma zinc concentration increased in children who received daily zinc supplementation for 15 d but not in those who received a zinc-fortified complementary food containing a similar amount of zinc. Expand
Micronutrient fortification of food and its impact on woman and child health: a systematic review
TLDR
The results for fortification in women showed that calcium and vitamin D fortification had significant impacts in the post-menopausal age group, and iron fortification led to a significant increase in serum ferritin and hemoglobin levels in women of reproductive age and pregnant women. Expand
Recent Advances in Knowledge of Zinc Nutrition and Human Health
TLDR
New guidelines on the assessment of population zinc status, as recommended by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the International Atomic Energy Agency (IAEA), and IZiNCG are summarized to provide an overview on several new advances in zinc metabolism. Expand
The Potential for Zinc Stable Isotope Techniques and Modelling to Determine Optimal Zinc Supplementation
TLDR
The application of zinc stable isotope tracer techniques to assess zinc physiology, metabolism and homeostasis and how these can address knowledge gaps in zinc supplementation pharmacokinetics are discussed to resolve optimal dose, frequency, length of administration, timing of delivery to food intake and choice of zinc compound. Expand
Role of zinc in human health with reference to African elderly: a review.
This review of the literature was conducted to assess dietary zinc intake among the African elderly, discuss the potential impact of current levels of zinc intake on their health, and to recommendExpand

Zinc fortification is considered a potentially useful strategy for the control of zinc deficiency, but the success of such intervention programs depends on the population's access to and consumptionExpand
Effect of a micronutrient fortificant mixture and 2 amounts of calcium on iron and zinc absorption from a processed food supplement.
TLDR
A mixture of fortificants containing NaFeEDTA, zinc sulfate or zinc methionine, ascorbic acid, and citric acid, but without calcium, can improve iron and zinc absorption from food products. Expand
Comparison of the effects of zinc delivered in a fortified food or a liquid supplement on the growth, morbidity, and plasma zinc concentrations of young Peruvian children.
BACKGROUND Zinc supplementation decreases morbidity from infections and increases growth of stunted children, but there is little information on functional responses to zinc delivered in fortifiedExpand
The effect of zinc-supplemented bread consumption on school children with asymptomatic zinc deficiency.
TLDR
The use of zinc-fortified bread was found to be an economical and readily accessible method to eliminate zinc deficiency and to prevent further occurrence. Expand
Use of Serum Zinc Concentration as an Indicator of Population Zinc Status
TLDR
Serum zinc concentration can be considered a useful biomarker of a population's risk of zinc deficiency and response to zinc interventions, although it may not be a reliable indicator of individual zinc status. Expand
Cofortification of iron-fortified flour with zinc sulfate, but not zinc oxide, decreases iron absorption in Indonesian children.
TLDR
Iron and zinc appear to be highly bioavailable from foods made from fortified flour, but zinc sulfate cofortification may have a detrimental effect on iron absorption. Expand
Longitudinal measurements of zinc absorption in Peruvian children consuming wheat products fortified with iron only or iron and 1 of 2 amounts of zinc.
TLDR
Although consumption of zinc-fortified foods may reduce FAZ, zinc fortification at the levels studied positively affects total daily zinc absorption, even after nearly 2 mo of exposure to zinc- Fortified diets. Expand
Absorption of zinc from wheat products fortified with iron and either zinc sulfate or zinc oxide.
TLDR
Either zinc oxide or zinc sulfate can be used to fortify wheat products consumed by presumably healthy persons, and isotopic tracers used to assess the absorption of mineral fortificants should have the same chemical form as the fortificant. Expand
Effects of iron and zinc supplementation in Indonesian infants on micronutrient status and growth.
TLDR
Iron supplementation combined with zinc was less effective than iron supplementation alone in reducing the prevalence of anemia, iron deficiency anemia and zinc deficiency, and in increasing hemoglobin and plasma ferritin concentrations. Expand
