Iron deficiency anemia is the most widespread micronutrient deficiency, according to the World Health Organisation. Eliminating iron deficiency anemia is a world-wide priority, and a three-pronged approach is suggested including increasing intakes of iron, controlling infectious disease with better hygiene and immunization, and improving overall nutrient intakes. Measures to increase iron intakes need to focus not only on increasing the iron content of the diet but also the absorption of iron. How can plant breeding techniques help in reducing iron deficiency anemia.

Whole grains, legumes and nuts provide plenty of minerals. However, they also contain high levels of phytate which binds with iron (Fe), calcium and zinc. Phytate-bound minerals cannot be absorbed. Iron bioavailability from vegetarian diets are lower (5-12%) compared to mixed diets (14-18%) and heme iron present in meat (25%). Phytates are a major reason that vegetarians and others who do not regularly eat red meat can become iron-deficient.
Iron-deficiency anemia (IDA) is the most common nutritional disorder globally.
Many of you will have heard low vitamin D levels are associated with an increased risk of Alzheimer’s disease. The risk was 2.25 higher for individuals who were severely deficient (serum 25(OH)D3 < 25 nmol/L) and 1.5 times higher for deficient (≥25 to <50 nmol/L). To be clear, this is a correlative study describing a relationship.
In a new report, Ford conclude baseline vitamin D concentrations do not predict mortality
The Philippine Rice Research Institute plans to conduct field tests for rice varieties which provide half of the vitamin A needed daily in a cup of beta-carotene enriched rice. The Executive Director, Ronilo Beronio, said this initiative will "help reduce incidences of vitamin A deficiency". According to the Food and Nutrition Research Institute, 40% of children (6mo - 5y) suffer from vitamin A deficiency, as do 1 of 5 pregnant and lactating Filipino women. Rice is also an excellent vehicle for vitamin A fortification. The 'Manila Declaration on Food Fortification' signed Dec 3-5, 1996 at the International Life Sciences Institute Regional Conference on Food Fortification urged
A new study published in the American Journal of Clinical Nutrition confirms the importance of beta-carotene as a source of vitamin A. The authors compared 1) beta-carotene-biofortified maize porridge, 2) white maize porridge fortified with beta-carotene, and 3) white maize fortified with vitamin A as retinyl palmitate. Both beta-carotene 'enriched' porridges contributed vitamin A. On a weight basis, the fortified beta-carotene maize was approximately 2.5 times more effective as a pro-vitamin A source than the 'modified' corn.
