"Selenium deficiency is rare among people in this country, the researchers said, where the nutrient is readily available in grains and vegetables."
That's not entirely correct. Brazil nuts is what you want:
NSF nutrient database, ranked list of the highest selenium containing foods.
1 Nuts, brazilnuts, dried, unblanched Selenium: 1917mcg
2 Sea lion, stellar, liver (Alaska Native) Selenium: 693mcg
3 Nuts, mixed nuts, without peanuts, oil roasted, with salt added Selenium: 421mcg
4 Pork, fresh, variety meats and by-products, kidneys, cooked, braised Selenium: 312mcg
5 Sea lion, stellar, kidney (Alaska Native) Selenium: 274mcg
6 Lamb, variety meats and by-products, kidneys, cooked, braised Selenium: 219mcg
7 Smelt, dried (Alaska Native) Selenium: 194mcg

"“Scott’s telomeres (endcaps of chromosomes that shorten as one ages) actually became significantly longer in space,” NASA explains. “While this finding was presented in 2017, the team verified this unexpected change with multiple assays and genomics testing. Additionally, a new finding is that the majority of those telomeres shortened within two days of Scott’s return to Earth.”

Most of Scott’s genes did indeed return to normal after a brief time back here on Earth, but not all of them. According to researchers, around 7% of Scott Kelly’s genes have shown long-lasting changes when compared to his brother’s. Those changes have remained for the two years since he returned to solid ground, which surprised even him."

Earth is toxic We stop aging in space? What?

"Glyphosate lowers the heparan sulfate, via the destruction of several pathways. Both Autistic and Alzheimers brains autopsies are radically low in sulfate. Without the daily (sleep) delivery of sulfates via melatonin, astrocytes cannot remove cellular debris with their lysozomes. Once repair is impossible, the "potholes" in cell life take over."

The gluten connection: the association between schizophrenia and celiac disease.

Schizophrenia affects roughly 1% of the population and is considered one of the top 10 causes of disability worldwide. Given the immense cost to society, successful treatment options are imperative. Based on initial findings, gluten withdrawal may serve as a safe and economical alternative for the reduction of symptoms in a subset of patients.
A review of the literature relevant to the association between schizophrenia and celiac disease (gluten intolerance) was conducted.
A drastic reduction, if not full remission, of schizophrenic symptoms after initiation of gluten withdrawal has been noted in a variety of studies. However, this occurs only in a subset of schizophrenic patients.
Large-scale epidemiological studies and clinical trials are needed to confirm the association between gluten and schizophrenia, and address the underlying mechanisms by which this association occurs.

"Canadian research suggests the disease risk from air pollution may have more to do with the genetic changes conferred by those aerial nasties than with the genes your mum and dad gave you. Sulphur dioxide, which smells like a just-struck match and comes mostly from coal-fired power plants, was linked to changes affecting 170 genes that made asthma and cardiovascular disease worse. back renewables!"

"This is fantastic news, do not let the system squelch it! Please note one correction: beta carotene (the orange in carrots) for many people is a very good source of antioxidant and it is converted into Vitamin A - retinol. This has many benefits besides growing new alveoli to reverse emphasema and COPD.

BUT: many folks cannot convert carotene into retinol, so a more universal source is fish oils which will contain both the retinol AND the Vitamin D3 which protects your liver from too much retinol. "

"Mental disorders may share molecular origins. Patterns of gene expression in the brains of people with five major mental disorders suggest some overlapping mechanisms. The findings help provide a framework for understanding the processes that affect the risk for developing mental disorders." From NIH Research Matters:

The Effects of High Concentrations of Vitamin C on Cancer Cells

The effect of high doses of vitamin C for the treatment of cancer has been controversial. Our previous studies, and studies by others, have reported that vitamin C at concentrations of 0.25–1.0 mM induced a dose- and time-dependent inhibition of proliferation in acute myeloid leukemia (AML) cell lines and in leukemic cells from peripheral blood specimens obtained from patients with AML. Treatment of cells with high doses of vitamin C resulted in an immediate increase in intracellular total glutathione content and glutathione-S transferase activity that was accompanied by the uptake of cysteine. These results suggest a new role for high concentrations of vitamin C in modulation of intracellular sulfur containing compounds, such as glutathione and cysteine. This review, discussing biochemical pharmacologic studies, including pharmacogenomic and pharmacoproteomic studies, presents the different pharmacological effects of vitamin C currently under investigation.
