− | <br>One of the most important governmental programs for vitamin supplementation is the Integrated Child Development Services (ICDS) program, which has existed in India since 1975. This program monitors the growth and development of children, and provides supplementary nutrition as well as education and primary health care for children under six and pregnant and lactating mothers. The program is implemented through a network of community-level anganwadi centers (AWC), which provides daily supplements both in the center as well as through take-home rations. Those supplements include doses of vitamin A and tablets of iron and folic acid, in order to prevent xerophtalmia - which can lead to blindness - and anaemia. | + | <br>One of the most important governmental programs for vitamin supplementation is the Integrated Child Development Services (ICDS) program, which has existed in India since 1975.

<br>However, the National Family Health Survey (NFHS-3) held in 2005-2006 in India reports that only 28% of children received those supplements and health care even though 4/5 of children under six lived in a region covered by an <i>anganwadi</i> center. In the 6 months preceding the survey, only 1/4 of the children between 12-35 months were given vitamin A supplements - and in 9 Indian states, this number falls to less than 20%. The access to ICDS has been improved in recent years, however, although access is still far from being universal (2). According to a national survey held in 2013-14, 46% of children aged 6-59 months had received doses vitamin A. | <br>However, the National Family Health Survey (NFHS-3) held in 2005-2006 in India reports that only 28% of children received those supplements and health care even though 4/5 of children under six lived in a region covered by an <i>anganwadi</i> center.

It is a very popular breakfast food across India, mostly in the south, and is often eaten with chutney. |

It is a very popular staple in the Indian diet, along with the crepe-like <i>dosa</i>, which is made of a similar but less coarse batter. Its two ingredients (rice and <i>dal</i>) are very cheap and widely available resources, and <i>idli</i> is commonly eaten by people who lack other types of food and who suffer from vitamin deficiencies. There is even a program that distributes free rice to the poorest populations in the country, the Public Distribution System (PDS); and in the city of Chennai and its suburbs, canteens called <i>Amma Unavagam</i> sell <i>idli</i> and other foods for very low prices (Rs1 for 1 <i>idli</i>). |

− | + | Besides its popularity and easy accessibility, the most interesting property of <i>idli</i> is that it is fermented. To cook <i>idli</i>, people soak rice and <i>dal</i> separately, then grind and mix them together, then let the batter ferment overnight. In the hot Indian climate, the batter ferments quickly and its volume can triple overnight. | |

Though the strains found in <i>idli</i> can be highly variable from one study to another, probably because the microbiome varies from different regions, we found that <i>Lactococcus lactis</i> and <i>Lactobacillus plantarum</i> are among the most common fermentative bacteria found in <i>idli</i> batter, while in the yeast population, <i>Saccharomyces cerevisiae</i> was always present. <font color="red">ADD SOURCES</font> Since we wanted our product to disrupt as little as possible the <i>idli</i>'s taste, we chose these organisms for production of the different vitamins and to improve iron availability, instead of adding new micro-organisms that weren’t already present in the <i>idli</i> batter that may have influenced the microbiome in an unpredictable manner. Many people who reviewed our project said that taste was of high importance, and would prefer that we modified microbes already present in the idli rather than add new ones. |
