要旨

Objective:

To investigate the impact of a college-level nutrition course on factors related to food agency.

Design:

Pre-post study.

Setting:

Four-year, large, public, land-grant university.

Participants:

Students enrolled in Nutrition 10, an introductory nutrition course (n = 1,873), and a comparison group of students not taking the course (n = 1,125) who completed both the pre- and post-surveys over an academic quarter (3 quarters total).

Variables Measured:

The 92-item questionnaire included the Money Expenditure Scale, Coping Strategy Scale, nutrition knowledge, and the 10-item US Department of Agriculture's Adult Food Security Survey Module.

Analysis:

Wilcoxon ranksum tests, ttests, and regression models examined associations between nutrition knowledge and key variables. Structural equation modeling assessed bidirectional relationships.

Results:

Students who took the class improved nutrition knowledge (+2.23 ± 5.14 points) compared with a decline in the comparison group (-0.42 points ± 3.55; P < 0.001). Structural equation modeling indicated increased nutrition knowledge was associated with lower Money Expenditure Scale (β = -0.03, P = 0.04) and Coping Strategy Scale (β = -0.17, P < 0.001) scores.

Conclusion And Implications:

Existing nutrition courses could help improve nutrition knowledge and factors related to food agency. Future research is needed to identify how improvements in nutrition knowledge translate into sustained behavioral changes that enhance food security in higher education.

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Microbial Nutrition

Microbial Nutrition

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels

Renal clearance of a drug is influenced by various factors, including its physicochemical properties and plasma levels. These factors play a significant role in determining how efficiently the kidneys eliminate a drug.
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...

Leveling Effect

Leveling Effect

In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
