Mercola calls sulfur the body's third most abundant mineral, needed for protein and enzyme structure, glutathione synthesis, detoxification, joint health and insulin function. He names fish, grass-fed beef and free-range poultry as the main dietary sources and MSM as a supplement form.

High potasium intake linked with lower risk of stroke
A meta-analysis covering 268,276 people and 8,695 strokes found each extra 1,000 mg of potassium a day tracked with 11 percent lower stroke risk, driven by ischemic stroke. Intracerebral hemorrhage risk fell 5 percent, while subarachnoid hemorrhage risk rose 8 percent.

Zinc lozenges shorten common cold duration
Pooling trials in The Open Respiratory Medicine Journal, Hemila found daily doses above 75 mg of zinc in lozenges shortened colds by 20 to 42%, while trials using less than 75 mg showed no benefit. High doses taste bad but no long-term side effects have been reported.
Minerals
High salt, low potassium means high death risk?
Americans eating a lot of sodium and little potassium were 50 percent more likely to die of any cause and twice as likely to die of a heart attack, in a CDC, Emory and Harvard analysis of NHANES data. Intake figures came from participants' recall of what they had eaten.

Advisory: In a Heat Wave, Your Body Needs More Salt (PR)
The Salt Institute advises anyone in extreme heat, particularly outdoor athletes, infants and the elderly, to replace sodium and potassium as well as water, warning that drinking water alone can bring on hyponatremia, whose symptoms resemble heat stroke.
Minerals
Food preservative sodium nitrate may protect against drug-induced heart failure
Mice given drinking water with sodium nitrate before and during doxorubicin treatment were less likely to suffer the heart damage the chemotherapy causes, VCU researchers found. The dose was four times the WHO acceptable daily intake, and nitrates carry their own cancer concerns.
Minerals
Potassium, magnesium reduces stroke risk in hypertensive women
Among 34,670 Swedish women followed 10.4 years, those with hypertension who ate the most potassium had 36 percent fewer strokes overall, and the most magnesium 37 percent fewer cerebral infarctions. Hypertensive women eating the most calcium were twice as likely to suffer intracerebral hemorrhage.
Minerals
Low salt may lower blood pressure, but not CVD death risk
Belgian researchers followed 3,681 people for about eight years and found cardiovascular deaths clustered in the group excreting the least sodium: 4.1 percent, against 0.8 percent among the highest excreters. Sodium excretion did not predict total deaths or non-fatal cardiovascular events.
Minerals
Americans still may not be getting enough calcium (PR)
Using NHANES data on 9,475 adults from 2003 to 2006, University of Connecticut and Yale researchers found self-reported calcium density highest in older age groups. Researchers quoted urge more supplementation and more nutrient-dense foods as energy intake falls with age.
Minerals
Calcium Intake Associated with Cardiovascular Disease
A reanalysis of 16,718 postmenopausal women in the Women's Health Initiative found calcium supplements, with or without vitamin D, raised heart attack and stroke risk by 13 to 22 percent, the BMJ reports. Earlier studies tied calcium intake to prostate cancer risk.

Dietary Supplement Fact Sheet: Zinc
Zinc helps the immune system fight bacteria and viruses, builds proteins and DNA, heals wounds and supports taste and smell. Daily amounts run from 2 mg in early infancy to 11 mg for adult men and 8 mg for women. Oysters are the best source; red meat, poultry and seafood follow.

NEW Studies Reveal Alarming Hidden Cause of Breast Cancer
Russell Blaylock reviews studies finding higher free iron and ferritin in the breast ductal fluid of cancer patients, with ferritin five times higher and aluminum about twice as high. He argues iron released from its binding proteins matters more than iron intake.
Minerals
Not all forms of selenium may prevent cancer
An Adelaide-led study treated lung cancer cells with two forms of selenium and found Se-methylselenocysteine killed more of them than selenomethionine, and that cells handled the two differently, which the researchers say may explain why selenium trials disagree.
Minerals
Zinc battles the common cold
A Cochrane review adding 15 trials with 1,360 subjects found people who took zinc within a day of cold symptoms were likelier to have recovered by day seven, and children taking zinc syrup or lozenges for five months or longer caught fewer colds. The best dose and formulation remain unknown.
Minerals
Magnesium Can Reduce Your Risk of Sudden Death
Following more than 88,000 women for 26 years, researchers reported in the American Journal of Clinical Nutrition that those with the highest blood magnesium had a 41 percent lower risk of sudden cardiac death. The authors say the association may or may not be causal.
Minerals
Calcium rich foods
A USDA appendix ranking non-dairy calcium sources by milligrams per standard serving, from fortified cereals and calcium-fortified soy beverage through sardines, tofu, canned salmon, collards and blackstrap molasses. The table notes that bioavailability varies between foods.
Minerals
Too much iron linked to high risk of Alzheimer's disease
Researchers in Argentina reported in the International Journal of Alzheimer's Disease that accumulation of copper, zinc and iron is linked to several neurodegenerative diseases, with high iron consistently found in the brains of Alzheimer's and Parkinson's patients.
Minerals
Kidney disease patients should avoid foods with high phosphorus
Eight chronic kidney disease patients had lower blood and urine phosphorus after a week of vegetarian eating than after a meat-based diet matched for protein and phosphorus. Researchers suspect plant phosphorus is less bioavailable, but say longer studies are needed.
