University of Nevada-Las Vegas researchers found 55 percent of more than 300 canned tuna samples from the top three U.S. brands exceeded the EPA's 0.5 ppm mercury standard, and 5 percent topped the FDA's 1.0 ppm limit. One of the three brands was consistently high.

This Common Food Ingredient Can Really Mess Up Your Metabolism (II)
The Corn Refiners Association is campaigning to present high fructose corn syrup as equal to table sugar, this installment argues, while the industry's newer crystalline fructose is 99.5% pure fructose and may carry arsenic, lead, chloride and heavy metals.
Chemical
This Common Food Ingredient Can Really Mess Up Your Metabolism (1)
Mercola argues that sugar, and fructose in particular, drives insulin resistance and weight gain along with raised blood pressure, triglycerides and LDL, gout, heart disease and liver damage, and notes Americans now eat far more calories than they did 25 years ago.

Bisphenol A in Food Containers Unsafe for Infants, Young Children - FDA
The FDA said in January 2010 that it now shares the National Toxicology Program's concern about BPA's possible effects on the brain, behavior and prostate gland in fetuses, infants and young children, after years of dismissing higher exposure estimates.
Chemical
Why Haven't Fruit & Vegetable Eaters Been Told About This Toxic Waste Overload?
The U.S. government is encouraging farmers to spread coal plant scrubber waste, a synthetic gypsum that also contains mercury, arsenic and lead, on their fields. The EPA says the toxic metals occur in only tiny amounts; some environmentalists say the effects on crops and health are poorly known.
Chemical
Artificial Sweeteners Don't Fool Your Brain
Eight cyclists rinsed their mouths without swallowing during hour-long rides: glucose beat saccharin slightly, and saccharin plus maltodextrin beat saccharin alone. fMRI scans showed the caloric combination activated the striatum and anterior cingulate, which saccharin alone did not touch.
Chemical
Fungi May Hold Key to Reducing Grapefruit Juice Interactions with Medications
Agricultural Research Service scientists found the fungus Aspergillus niger either bound or enzymatically broke down the furanocoumarins in grapefruit juice that interfere with drug metabolism. Dried, pulverized morel, oyster and button mushrooms also removed them.
Chemical
Sugar May Be Bad, But This Sweetener Is Far More Deadly
Mercola cites a trial in which 16 volunteers on a controlled high-fructose diet for 10 weeks grew new fat cells around the heart, liver and other digestive organs and showed food-processing abnormalities linked to diabetes and heart disease. A glucose group did not.
Chemical
Acrylamide may boost certain breast cancers
Among 62,573 Dutch women followed 13 years, acrylamide intake showed no link to overall or receptor-negative breast cancer. Among never-smokers, the highest intakes tracked with 31% to 47% higher risk of ER-positive, PR-positive and joint receptor-positive tumours. The authors call for confirmation.
Chemical
Fructose may be unhealthy
G.A. Bray concludes in Current Opinion in Lipidology that fructose is hazardous to cardiometabolic health. His analysis found people in the top quantile of soft drink consumption were 24% more likely to have cardiometabolic disease than those in the bottom.
Chemical
Trans fat raises death risk from sudden cardiac arrest
Following 87,000 nurses for 26 years, Harvard researchers found no overall link between trans fat and sudden cardiac death. Among women who already had coronary heart disease, though, those getting 2.5 percent of calories from trans fat were three times more likely to die suddenly.
Chemical
Trans fat and MSG impair learning and memory
Mice fed a diet combining trans fat and MSG gained central fat, developed worse cholesterol profiles and did poorly at locating a hidden platform in a spatial memory test, according to a study in Physiology & Behavior.
Chemical
Titanium dioxide may raise cancer risk
UCLA researchers gave mice drinking water containing titanium dioxide nanoparticles and saw single- and double-strand DNA breaks, chromosome damage and inflammation by day five. The particles build up in organs, and Robert Schiestl advises limiting intake.

BPA damages male reproductive system
A five-year study of 634 Chinese factory workers found those in BPA facilities had four times the risk of erectile dysfunction and seven times the risk of ejaculation difficulty. Exposures were about 50 times those of American men, so lower-dose effects remain unknown.

Coffee break: Compound brewing new research in colon, breast cancer (Press Release)
Texas AgriLife researchers found trigonelline, a compound in coffee, behaves like estrogen in their studies, which may make it a factor in estrogen-dependent breast cancer but beneficial against colon cancer. Clinton Allred says he sees no reason for concern about drinking coffee.
Chemical
High Intake of High Fructose Corn Syrup Linked to High Blood Pressure
Diana Jalal's team studied 4,528 adults without diagnosed hypertension and found those consuming more than 74 grams of fructose a day, roughly 2.5 sugary soft drinks, faced higher blood pressure independent of other factors.
Chemical
Fructose Tied to Higher Blood Pressure
Two studies offered the first evidence that a diet high in fructose raises blood pressure in men, and one suggested people eating junk food and sweetened drinks at night may gain weight faster. Mercola disputes the claim that fructose is no worse than other sugars.
Chemical
Artificial Sweeteners -- More Dangerous than You Ever Imagined
Mercola argues that aspartame-sweetened products are neither safe nor a healthier alternative to sugar, and blames marketing by food companies, regulators and politicians for the sense of security consumers feel about artificial sweeteners.
