Summary
Accurate iodine content data for foods and supplements are now available. This information helps estimate intake and guide public health, especially for at-risk groups like pregnant women and children.
Area of Science:
- Nutritional Science
- Food Chemistry
- Public Health
Background:
- Accurate iodine intake data is crucial for public health.
- Estimating iodine intake requires comprehensive food and supplement data.
- Identifying major iodine contributors aids in dietary guidance development.
Purpose of the Study:
- To compile and release comprehensive data on the iodine content of foods and dietary supplements.
- To support the development of general population intake estimates.
- To identify key sources of dietary iodine.
Main Methods:
- Samples of diverse foods (seafood, dairy, eggs, etc.) and dietary supplements were collected.
- Iodine content was determined using inductively coupled plasma mass spectrometry.
- Rigorous quality control measures were implemented throughout the analysis.
Main Results:
- The USDA, FDA, and ODS-NIH released a database for the Iodine Content of Common Foods.
- Iodine data for dietary supplements are available in separate ODS databases.
- These databases provide essential iodine content information for various food matrices and supplements.
Conclusions:
- The compiled iodine databases are vital for monitoring iodine status in the U.S. population.
- Data facilitates the development of targeted dietary guidance, particularly for vulnerable subgroups.
- This information is critical for addressing iodine deficiency, especially in women of reproductive age and young children.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:25Drug Regulation
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
01:23Redox Titration: Iodimetry and Iodometry
Iodometry and iodimetry are analytical methods used to determine the concentration of oxidizing or reducing agents using iodine. In iodometric titrations, the oxidizing analyte solution is usually acidified and treated with an excess of iodide ions, which generates an equivalent amount of iodine in equilibrium with triiodide. The released iodine is subsequently titrated directly against a standardized reducing agent. As the dilute iodine color becomes pale yellow, a few drops of freshly...
01:28Proteins: Dietary Sources and Requirements
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
01:30Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
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 colonic...

01:29Clinically Relevant Drug Product Specifications: Methods of Establishment
Product specifications define the acceptable quality of a pharmaceutical product by ensuring identity, purity, potency, and strength. These specifications serve as benchmarks during development, manufacturing, and post-approval quality control. Clinically relevant specifications are particularly important because they directly relate to a drug's safety and efficacy in clinical use.Dissolution studies are critical biopharmaceutic tools that link in vitro behavior to in vivo performance. They...
