Qingqing Chen's team exposed rat liver cells to silica nanoparticles and saw many lose viability within 24 hours, with apoptosis and oxidative stress rising by dose. The authors suggest consumers may be better off avoiding supplements and processed foods containing silica.

Roundup harms beneficial gut bacteria
Leipzig University scientists testing poultry gut bacteria in vitro found highly pathogenic species resisted Roundup while beneficial bacteria were moderately to highly susceptible, which the piece offers as a basis for farmer reports of gut disease in animals fed GM soy.

Nanoparticles are toxic - study confirms
Brine shrimp larvae exposed to zinc or zinc oxide nanoparticles showed no acute effects at 24 hours but died at high rates by 96 hours, with the particles accumulating in their guts. Smaller particles proved more toxic, and zinc more toxic than zinc oxide.

How Safe Are Eggs to Eat?
A British Medical Journal article finds an egg a day is not associated with higher risk of coronary heart disease or stroke, but the piece lines up contrary findings: Circulation tied an egg a day to heart failure risk in doctors, and other journals link eggs to diabetes and ovarian cancer.

If fluoridation was as good as they say it is
Cairns and the Doomadgee Aboriginal Shire Council both voted to end water fluoridation, with Cairns calling it involuntary medication of residents. The bulletin also notes that Paul Connett's challenge to debate former CDC oral health director William Maas has gone unanswered for 25 days.

Cleaning jobs linked to asthma risk (PR)
Imperial College London researchers tracking 9,488 Britons born in 1958 found nine percent developed asthma by age 42, with workplace exposures behind one in six adult-onset cases. Of 18 occupations clearly linked to asthma, four were cleaning jobs; farmers had about four times the risk.

BPA free? Alternative can be as bad as BPA
Manufacturers replacing bisphenol A with bisphenol S may not have solved the problem. A study in Environmental Health Perspectives reports that BPS disrupts hormone activity as BPA does, and the two share a similar structure and toxicity.

It Can Impair Your IQ, Yet Nearly Everyone Drinks It Daily
Mercola argues fluoridation's dental benefit is marginal and still debatable while its risks are not, calling fluoride an industrial waste product that can carry lead and arsenic, reach toxic exposure from water and toothpaste, and damage bones, brain and endocrine system.
Chemical
Paul Connett explains why he continues to fight fluoridation
Paul Connett's bulletin reports that San Jose's water district will add fluoride, blames California's 1995 mandatory fluoridation law for that loss and earlier ones in San Diego and the Metropolitan district, and urges readers to block similar mandates in other states.

Understand ingredients in M&M'S Chocolate Candy
An ingredient-by-ingredient commentary on M&M'S, noting milk chocolate lacks the heart-protective compounds of dark chocolate, that the sugar may come from genetically modified beet, and that milk fat carries naturally occurring trans fat.

Outlawed in the EU, Unleashes Deadly Bacteria... Did You Eat It Today?
Livestock account for 80 percent of the roughly 30 million pounds of antibiotics sold in the US yearly, mostly fed at low doses to speed growth rather than treat infection. Mercola argues this breeds resistant bacteria such as MRSA, tied to 94,000 infections and 18,000 deaths a year.

More Independent Voices Speak Up on Fluoridation
Kirkland Lake, Ontario council voted unanimously to stop fluoridating the town's water. Fluoridation had already halted when the tanks needed replacing at a cost of up to $375,000, but council members went on to argue from ethics, doubtful benefit, and babies taking in adult doses.

Artificial Sweeteners Cause Greater Weight Gain than Sugar, Yet Another Study Reveals
A Brazilian team fed rats yogurt sweetened with aspartame, saccharin or sugar alongside their chow for 12 weeks and reports in Appetite that both artificial sweeteners produced more weight gain than sucrose, even though total calorie intake was similar across the groups.

Fluoride induces oxidative stress, melatonin helps reduce the toxicity
Indian researchers gave male rats 5 or 10 mg of sodium fluoride per kg daily for 60 days and saw lower body and organ weights, raised lipid peroxidation and depleted antioxidants in the testis. Melatonin at 10 mg/kg significantly protected gonadal function.

Nanoparticles used in food, dietary supplements and cosmetics can induce mutation
A Pharmazie study found 70-nm amorphous silica nanoparticles triggered more reactive oxygen species in Langerhans-like cells than micron-sized silica did. The article notes such particles are widely used in food, supplements and cosmetics without adequate toxicity testing.
