Is iodine intake adequate in Norway?
Summary
Iodine intake remains low in Norway, particularly affecting vulnerable groups like women of childbearing age. Public health initiatives are needed to address this widespread nutritional deficiency.
Area of Science:
- Nutrition Science
- Public Health
Background:
- Norwegian National Nutrition Council identified widespread inadequate iodine intake in 2016.
- Urgent measures were recommended to address iodine deficiency.
- This review focuses on iodine intake in Norway since January 2016.
Purpose of the Study:
- To summarize recent literature on iodine intake in Norway.
- To identify populations at risk for inadequate iodine intake.
Main Methods:
- Literature search conducted in PubMed and Embase.
- Included 13 articles reporting dietary iodine intake or urinary iodine concentration.
Main Results:
- Inadequate iodine intake is prevalent among women of fertile age, pregnant and breastfeeding women, exclusively breastfed infants, the elderly, vegans, and immigrants.
- Limited dietary sources of iodine, particularly low intake of milk and white fish, increase vulnerability.
Conclusions:
- Inadequate iodine intake is a significant concern, especially for women of fertile age.
- Healthcare providers should consider recommending iodine-rich foods or supplements to at-risk groups.

Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

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...

01:13Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene
7.5K
Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid. Astatine is a highly unstable radioactive element, so currently, most of its properties are unknown due to its short half-life. Tennessine is a synthetic element also predicted to be in this group.
