First trimester diet is most important because in first few weeks the fetus relies on simple diffusion of oxygen & nutrients from the mother’s blood. From about 12 weeks the placenta controls all. Essential nutrients (Wendy Martinez et al., 2006) - thiamine, riboflavin, folate/folic acid, vit. A,C&D, calcium, phosphorus, magnesium, zinc, copper, selenium, iodine, omega 3 fatty acids etc. But important is folate/ folic acid & vit.D. Supplementary folic acid is needed prior to conception & up until 12 weeks gestation to lower the risk of neural tube defects. Therefore due to nutritional deficiency congenital fetus anomalies are found and for early detection of all these anomalies for healthy population it is most important so now a day’s first trimester anomalies scan are started. So for prevention of anomalies as well as healthy population to study conceptual Masanumasik aaahar according to Bruhtrayi. Which fulfill all nutritional requirements and help to avoid such a nutritional related congenital anomalies. Prevalence (Andres et al., 2006) - Overall prevalence of congenital anomalies in study population was 2.6%. Out of these 64.4% were detected by first trimester anomaly scan. Detailed first trimester anomaly scan and first trimester fetal echocardiography should be performed to detect the fetal anomalies early.
