Abstract
Background: Excessive consumption of cola beverages is accompanied by numerous public health risks. But besides these well-known adverse effects, recently, several medical articles have been published that show some indications for cola beverages in clinical practice like resolution of gastrointestinal or feeding tube obstructions, increasing bioavailability and palatability of other medications, rehydration and other uses in healthcare settings. These approaches are not without shortcomings and complications.Methods:In this systematic review we tried to explore these new uses for practitioners and also reemphasize on the most evidence-based complications of cola consumption like bone loss and metabolic and cardiovascular adverse effects in cases of misuse and overuse from both clinical and nutritional points of view via searching the PubMed database.Results:We chose 145 journal articles from the most relevant ones plus 30 extra references and categorized their topics in two classes of medical uses and adverse effects.Conclusion:It could be stated that cola beverages have demonstrated interesting uses and benefits in medicine but their use should be regulated as strict as possible.

Abstract
A key distinguishing feature of Latin America is that 75% of the population is urban, and this proportion is projected to rise to 82% by 2025. Because markets for processed foods are more developed in urban than in rural areas, fortification has a comparative advantage in Latin America relative to other regions. In fact, fortification has been highly successful in Latin America. Salt iodination programmes are the most widespread, followed by fortification of sugar with vitamin A; fortification of wheat with thiamine, riboflavin, niacin, and folic acid; and fortification of margarine. At least 13 Latin American countries now have vitamin A supplementation programmes, which are relatively new to Latin America. A mix of types of fortification, supplementation, and food-based interventions will be needed in the future. Efforts should continue in the implementation of activities such as home gardens, small-animal production, and promotion of edible, native plants. Genetic manipulation through plant-breeding can alter in a positive way desirable functional properties of foods as well as the concentration and properties of macro- and micronutrients. The benefits of functional characteristics bred into plants have been clearly demonstrated (e.g., fatty acid profiles, delayed ripening), but not the benefits for human nutrition, except in laboratory situations. The plant-breeding approach needs additional, interdisciplinary research at various points in the food chain to establish the benefit for human nutrition.

Abstract
Common beans are a staple food and the major source of iron for populations in Eastern Africa and Latin America. Bean iron concentration is high and can be further increased by biofortification. A major constraint to bean iron biofortification is low iron absorption, attributed to inhibitory compounds such as phytic acid (PA) and polyphenol(s) (PP). We have evaluated the usefulness of the common bean as a vehicle for iron biofortification. High iron concentrations and wide genetic variability have enabled plant breeders to develop high iron bean varieties (up to 10 mg/100 g). PA concentrations in beans are high and tend to increase with iron biofortification. Short-term human isotope studies indicate that iron absorption from beans is low, PA is the major inhibitor, and bean PP play a minor role. Multiple composite meal studies indicate that decreasing the PA level in the biofortified varieties substantially increases iron absorption. Fractional iron absorption from composite meals was 4%–7% in iron deficient women; thus the consumption of 100 g biofortified beans/day would provide about 30%–50% of their daily iron requirement. Beans are a good vehicle for iron biofortification, and regular high consumption would be expected to help combat iron deficiency (ID).

Abstract
BACKGROUND The common bean is a staple crop in many African and Latin American countries and is the focus of biofortification initiatives. Bean iron concentration has been doubled by selective plant breeding, but the additional iron is reported to be of low bioavailability, most likely due to high phytic acid (PA) concentrations. OBJECTIVE The present study evaluated the impact of PA on iron bioavailability from iron-biofortified beans. METHODS Iron absorption, based on erythrocyte incorporation of stable iron isotopes, was measured in 22 Rwandese women who consumed multiple, composite bean meals with potatoes or rice in a crossover design. Iron absorption from meals containing biofortified beans (8.8 mg Fe, 1320 mg PA/100 g) and control beans (5.4 mg Fe, 980 mg PA/100 g) was measured with beans containing either their native PA concentration or with beans that were ∼50% dephytinized or >95% dephytinized. RESULTS The iron concentration of the cooked composite meals with biofortified beans was 54% higher than in the same meals with control beans. With native PA concentrations, fractional iron absorption from the control bean meals was 9.2%, 30% higher than that from the biofortified bean meals (P < 0.001). The quantity of iron absorbed from the biofortified bean meals (406 μg) was 19% higher (P < 0.05) than that from the control bean meals. With ∼50% and >95% dephytinization, the quantity of iron absorbed from the biofortified bean meals increased to 599 and 746 μg, respectively, which was 37% (P < 0.005) and 51% (P < 0.0001) higher than from the control bean meals. CONCLUSIONS PA strongly decreases iron bioavailability from iron-biofortified beans, and a high PA concentration is an important impediment to the optimal effectiveness of bean iron biofortification. Plant breeders should focus on lowering the PA concentration of high-iron beans. This trial was registered at clinicaltrials.gov as NCT01521273.

Effect of sodium iron ethylenediaminetetra-acetate (NaFeEDTA) on haemoglobin and serum ferritin in iron-deficient populations: a systematic review and meta-analysis of randomised and quasi-randomised controlled trials. Br J Nutr 2008; 100:1169-78.

Abstract
We aimed to synthesise evidence to assess the effect and safety of NaFeEDTA on Hb and serum ferritin in Fe-deficient populations. We performed a systematic review, identifying potential studies by searching the electronic databases of Medline, Cochrane Library, Embase, WHO Library and China National Knowledge Infrastructure. We also hand-searched relevant conference proceedings and reference lists. Finally, we contacted experts in the field. The selection criteria included randomised or quasi-randomised controlled trials of NaFeEDTA compared with placebo. Hb, serum ferritin and adverse effects were outcomes of interest. Inclusion decisions, quality assessment and data extraction were performed by two reviewers independently. Seven studies met the inclusion criteria. All included studies assessed the effect of NaFeEDTA on Hb concentration, four studies assessed the effect on serum ferritin concentration, and one study on serum Zn concentration. After the intervention, Hb concentration and serum ferritin concentration were both higher in the NaFeEDTA group compared with the control group. For Hb, data from six studies could be pooled and the pooled estimate (weighted mean difference) was 8·56 (95 % CI 2·21, 14·90) g/l (P = 0·008). For serum ferritin, data from four studies could be pooled and the pooled difference was 1·58 (95 % CI 1·20, 2·09) μg/l (P < 0·001). Subgroup analysis indicated that a lower baseline Hb level was associated with a greater increase in Hb concentration. No significant difference in serum Zn concentration was found. We concluded that NaFeEDTA increased both Hb concentration and serum ferritin concentration substantially in Fe-deficient populations, and could be an effective Fe preparation to combat Fe deficiency.

Abstract
Iron deficiency can be caused not only by diets deficient in iron but by poor absorption of available dietary iron. Extrinsically tagging foods with radioiron allows the exact measurement of iron absorbed from heme and nonheme iron foods. It has furthered the study of the effect of enhancers and inhibitors of iron absorption. As a result, we have a greater understanding of why iron deficiency and iron deficiency anemia are prevalent in populations of low socioeconomic status and of which food vehicles and iron compounds are most suitable for iron fortification.

Abstract
The effect of food processing on the biological availability of iron in iron-fortified foods is critically reviewed. Studies on changes in the chemistry of the iron in processed foods are examined. Various iron sources currently used in food fortification in the U.S. are defined with emphasis on their biological availabilities under various conditions. The availability of iron in foods depends upon numerous factors, most of which are not fully understood. A factor which is often overlooked is the interaction of the iron with the food during events such as cooking or processing. Chemical changes in the iron compounds occur which may correlate with changes in the biological availability.
