Omega Pills Do Not Work

Wednesday, September 2nd, 2015

A new study published in the Journal of the American Medical Association concludes Omega-3 pills have no effect on the health of your brain; however, eating whole seafood increases your risk mercury poisoning. The Food and Drug Administration recommends eating more low-mercury seafood.

“The hypothesis was that [the supplements] would have an effect,” study author Emily Chew tells The Salt. But “we found there was absolutely no effect on the cognitive decline in this group over time,” says Chew, who is the deputy clinical director at the National Eye Institute, part of the National Institutes of Health.

“Omega-3s [found in fish] are important, we think, because they reduce inflammation and help neurons function well,” says researcher Joseph Hibbeln of the National Institutes of Health.

Heavy Metals In Your Diet

Thursday, January 23rd, 2014

Heavy metals can either be an essential part of your diet or toxic and deadly. For instance, iron is needed for blood; however, men can build up toxic levels of iron as they grow older.

Living organisms require varying amounts of “heavy metals”. Iron, cobalt, copper, manganese, molybdenum, and zinc are required by humans. Excessive levels can be damaging to the organism. Other heavy metals such as mercury, plutonium, and lead are toxic metals and their accumulation over time in the bodies of animals can cause serious illness. Certain elements that are normally toxic are, for certain organisms or under certain conditions, beneficial. Examples include vanadium, tungsten, and even cadmium.

Heavy metal toxicity can result in damaged or reduced mental and central nervous function, lower energy levels, and damage to blood composition, lungs, kidneys, liver, and other vital organs. Long-term exposure may result in slowly progressing physical, muscular, and neurological degenerative processes that mimic Alzheimer’s disease, Parkinson’s disease, muscular dystrophy, and multiple sclerosis. Allergies are not uncommon, and repeated long-term contact with some metals (or their compounds) may cause cancer.

Do not eat:

  • Shark
  • Swordfish
  • King Mackerel
  • Tilefish

Nearly all fish and shellfish contain traces of mercury… some fish and shellfish contain higher levels of mercury that may harm an unborn baby or young child’s developing nervous system. The risks from mercury in fish and shellfish depend on the amount of fish and shellfish eaten and the levels of mercury in the fish and shellfish.
