Mathematical approaches to food nutrient content estimation with a focus on phenylalanine
<p>Managing the intake of a certain nutrient can be an effective treatment for some inherited metabolic disorders. An example of such dietary treatments is for phenylketonuria (PKU), for which patients must follow a low-phenylalanine diet for life. Some food databases provide the phenylalanine …

Nutrient content of school lunches and packed lunches as consumed by elementary school students
This study compared nutrient content and intake of student school and home-packed lunches. Food intake was estimated by weighing the food and leftovers of 114 elementary school children. Eighty-one percent (n = 92) consumed school lunches and nineteen percent (n = 22) consumed packed lunches. A …

Changes in Leaf Area and Nutrient Content of Celtis spp. Across a Precipitation Gradient in Texas
Nitrogen is a key nutrient for cell and protein function in both plants and animals, and the ratio of carbon to nitrogen in leaves is a good indicator of nutrient quality within an ecosystem. Studies have shown that an increase in precipitation increases leaf size and the C/N ratio, but can …

Investigating the Relationships Between Age and Depth of Stockpiled Topsoil with Its Nutrient Content: An Analysis of Responsible Factors and Potential Consequences
… Alberta. The samples were analyzed for pH, macronutrients, micronutrients, total organic carbon and organic matter. Descriptive statistics and correlation analysis were used to determine if there were significant chemistry changes between age and depth of stockpiled soils. The results indicated a …
