Iodine, a global deficiency

Iodine, Over a third of the global population is exposed to iodine deficiency, especially in the mountains.

Serious iodine deficiency during pregnancy can result in stillbirth, spontaneous abortion and congenital abnormalities such as cretinism Role of Iodine in Metabolism https://pubmed.ncbi.nlm.nih.gov/28103... Urinary Iodine Concentration https://www.kcl.ac.uk/open-global/bio... In healthy, iodine-replete adults more than 90% of dietary iodine is absorbed from the small intestine and more than 90% is excreted within 24-48 hours Functions Control of metabolic rate, energy levels, weight management, brain function, cardiovascular health, foetal and child development, reduced still births, infection protection in children, breast, ovary, uterus protection, prostate. Many organs can also actively accumulate iodine: salivary glands, stomach, lactating mammary gland, ovary, prostate, pancreas.

Changes in Dietary Iodine Explains Increasing Incidence of Breast Cancer with Distant Involvement in Young Women https://pmc.ncbi.nlm.nih.gov/articles... Fibrocystic breast disease Iodine deficiency is associated with fibrocystic breast disease Fibrocystic breast disease can be effectively treated with iodine Fibrocystic breast disease affects at least 50% of women of child-bearing age, and is associated with an increased risk of developing breast cancer. Breast cancer Increasing breast cancer in younger women since mid-1970s Often presenting late Iodine deficiency has been proposed to play a causative role in the development of breast cancer Dietary iodine has also been previously proposed to play a protective role in breast cancer Japanese women, have exceptionally low incidence of breast cancer Emigration of Japanese women, adopting a western diet, associated with higher breast cancer rates. Iodine is taken up by the sodium/iodide symporter in the breast This is important in promoting the development of normal versus neoplastic breast tissue development Reduce breast cancer Vit D and K2, phytonutrients, cruciferous veg, cauliflower, cabbage, kale, garden cress, bok choy, broccoli, Brussels sprouts, omega 3 Mechanism of action of iodine's anticancer effect Antioxidant, iodide has been found to be highly efficient in scavenging reactive oxygen species Iodine also has well-known anti-inflammatory and immunomodulatory effects Iodine promotes differential apoptosis Iodine promotes of P53 tumour suppressor gene activity Iodine plays a role in the development and maintenance of healthy breast tissue Women with goitre have three times more breast cancer Iodine deficiency results in “hyperresponsiveness” to oestrogen, resulting in increased cell proliferation, abnormal changes within nuclei, Iodine is necessary for breast remodelling during lactation, and pregnancy Young women and pregnant women, have lower urinary iodine levels than men of similar age. Women of childbearing age exhibited the lowest urinary iodine levels of any age group. Atypia is seen more in iodine deficiency in human and animal models Temporal Changes in Body Iodine There has been a drop in urinary iodine in young women as well as in the general population, since the 1970s Nutrition Examination Surveys, A significant decrease in urinary iodine levels in the overall population during the period 1988-1994 as compared to the period 1971-1974 (P less than 0.0001). Percentage of people with iodine deficiency, (below 50 μg/L) (WHO recommend 100- 199 - 249 μg/liter urinary iodine, less than 100 μg/L indicates that the population's iodine intake is insufficient.) 1971-1974 2.6% during the period 1988-1994 14.5% of the population iodine deficient by WHO criteria, representing a 5.6-fold increase since early 1970s Females showed a higher frequency of iodine deficiency than males (15.1% versus 8.1%). Lower Urinary iodine levels in black relative to white women may also explain the greater increase in frequency of distant breast cancer in black women 2005-2008 Pregnant women had median urinary iodine levels of 125 μg/liter, and 56.9% had levels less than the WHO recommended 150-249 μg/liter Lancet, 2013 https://pubmed.ncbi.nlm.nih.gov/23706...
