An extensive study compared school lunches planned to meet a specific nutrient standard (NSM) with those planned according to the Type A pattern. Average daily participation, food and labor costs, accuracy of the menus, and differences in the four-week menus between the two methods are reported. Twenty-nine menu planners representing a variety of living environments quickly learned the NSM method and enthusiastically planned and served the Type A and NSM test menus to fifth and tenth grade students. Type A data were collected in the fall and NSM data in the spring of the 1972-73 academic year. Changing from Type A to NSM menu planning resulted in no significant change in lunch participation or food and labor costs. Work functions also did not vary significantly when the menu planning method was changed. Menu planners of varying education and experience successfully planned accurate NSM menus and endorsed the method as an exciting and viable alternative to the Type A pattern. Sixty per cent preferred NSM due to its nutrient assurance, flexibility, and potential for nutrition education.

Trace elements are often omitted from chemically defined growth media. From established properties of trace elements, we deduce that this omission makes experiments unnecessarily sensitive to unavoidable contamination with trace elements. We confirm this experimentally by growing 11 bacterial strains in high replicate with and without supplementing trace elements, keeping all other conditions as fixed as possible to isolate the effect of trace elements.

For instance, due to existing regulatory gaps, certain pharmaceutical entities commit violations of regulatory requirements, such as failing to register medicinal products and selling them under the guise of dietary and/or food supplements. Conversely, physicians may recommend ordinary dietary and food supplements to patients as if they were medicinal products.

The aim of the study was to determine the nutrient composition of human milk (HM) of Indian mothers and investigate its association with maternal and infant anthropometric measures. Human milk is an ideal source of nutrition for optimum growth and development of infant. Among Indian mothers, HM composition data is scanty, especially during prolonged lactation.

We previously identified the bacterial species, , which uses nutrient-induced filamentation as a novel mechanism for cell-to-cell spreading in the intestinal epithelial cells of a nematode host. To further investigate the conservation of nutrient-induced filamentation in Bordetellae, we utilized the turkey-infecting species which filaments in vitro when switched from a standard growth media to an enriched media.
