Billions With Nutrition Deficiency!?
Almost no one gets enough selenium. Officially, at least a billion — with a B — people have a selenium deficiency.1 But I suspect the numbers are much higher than that. You can’t get enough selenium from food alone anymore. That’s true even if you eat a healthy, varied diet. And you can thank Big Agra for that. With their harsh pesticides, synthetic fertilizers, and single-crop strategy, these massive farms have stripped the nutrients out of the soil. No nutrients in the soil mean no nutrients in the food. All of this makes it difficult — if not impossible — to get even some of the daily selenium you need to ...

The role of glutathione peroxidase-1 in health and disease
Free Radic Biol Med. 2022 Jun 9:S0891-5849(22)00224-6. doi: 10.1016/j.freeradbiomed.2022.06.004. Online ahead of print.ABSTRACTGlutathione peroxidase 1 (GPx1) is an important cellular antioxidant enzyme that is found in the cytoplasm and mitochondria of mammalian cells. Like most selenoenzymes, it has a single redox-sensitive selenocysteine amino acid that is important for the enzymatic reduction of hydrogen peroxide and soluble lipid hydroperoxides. Glutathione provides the source of reducing equivalents for its function. As an antioxidant enzyme, GPx1 modulates the balance between necessary and harmful levels of reactive...

What the Science Says About the Health Benefits of Vitamins and Supplements
From multivitamins and melatonin to fiber and fish oil, Americans who are trying to boost their health and immunity have a plethora of supplements to choose from. An estimated 58% of U.S. adults ages 20 and over take dietary supplements, according to the U.S. Centers for Disease Control and Prevention, and the supplement industry is valued at more than $30 billion a year. Supplement use has been growing rapidly over the past few decades along with the wellness industry. “The popular belief is that a supplement is going to be helpful for promoting health,” says Fang Fang Zhang, a professor at Tufts University&rs...

Selenium Drives a Transcriptional Adaptive Program to Block Ferroptosis and Treat Stroke
Publication date: Available online 2 May 2019Source: CellAuthor(s): Ishraq Alim, Joseph T. Caulfield, Yingxin Chen, Vivek Swarup, Daniel H. Geschwind, Elena Ivanova, Javier Seravalli, Youxi Ai, Lauren H. Sansing, Emma J. Ste.Marie, Robert J. Hondal, Sushmita Mukherjee, John W. Cave, Botir T. Sagdullaev, Saravanan S. Karuppagounder, Rajiv R. RatanSummaryFerroptosis, a non-apoptotic form of programmed cell death, is triggered by oxidative stress in cancer, heat stress in plants, and hemorrhagic stroke. A homeostatic transcriptional response to ferroptotic stimuli is unknown. We show that neurons respond to ferroptotic stimul...

Osteoporosis and Sarcopenia Increase Frailty Syndrome in the Elderly
Conclusions World population is aging and the increase in life expectancy is often unhealthy. In particular, musculoskeletal aging, which leads to sarcopenia and osteoporosis, has several causes such as changes in body composition, inflammation, and hormonal imbalance. Sarcopenia, osteoporosis, and more frequently, sarcopenic obesity are commonly associated with aging and frequently closely linked each other, often leading to the development of a frailty syndrome. Frailty syndrome favors an increased risk of loss function in daily activities, for cardiovascular diseases, cancers, falls, and mortality. As the number of eld...

A Nested Case–Control Study on Plasma Vitamin E and Risk of Cancer: Evidence of Effect Modification by Selenium
ConclusionsThis study suggests that higher levels of plasma vitamin E are associated with reduced risk of gastrointestinal cancer. High vitamin E decreased the risk of total cancer among patients with high selenium levels, but increased the risk of total cancer among those with low selenium levels.

Plasma Metal Concentrations and Incident Coronary Heart Disease in Chinese Adults: The Dongfeng-Tongji Cohort
Conclusions: Our study suggested that incident CHD was positively associated with plasma levels of titanium and arsenic, and inversely associated with selenium. Additional research is needed to confirm these findings in other populations. https://doi.org/10.1289/EHP1521 Received: 22 December 2016 Revised: 17 September 2017 Accepted: 19 September 2017 Published: 19 October 2017 Address correspondence to T.
