Summary
Nutrient profiling systems (NPSs) show varied accuracy in assessing food healthiness. Nutri-Score demonstrated substantial evidence for criterion validity, linking healthier food choices to reduced disease risk and mortality.
Area of Science:
- Nutritional science
- Public health
- Food science
Background:
- Nutrient profiling systems (NPSs) employ algorithms to assess the nutritional quality of foods and beverages.
- Criterion validation is crucial for NPS accuracy, evaluating the link between NPS-rated healthier foods and objective health outcomes.
Conclusions:
- A limited number of criterion validation studies exist relative to the number of NPSs available.
- Increased focus on conducting and reporting criterion validation studies in diverse settings is recommended to enhance confidence in NPS accuracy.

18.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.
