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.

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.
Biological
Understand e coli
The CDC estimates 73,000 infections and 61 deaths a year in the U.S. from E. coli O157:H7. Cattle are the main source, and the Shiga toxin these strains produce can damage the lining of the intestines and kidneys, often causing bloody diarrhea and sometimes kidney failure in young children.
Biological
New Vaccines May Help Thwart E. coli O157:H7
ARS microbiologists Vijay Sharma and Thomas Casey developed two vaccine forms built on E. coli O157:H7 strains missing the hha gene, or hha plus sepB, which produce immunogenic proteins intended to stop the bacteria from colonizing cattle intestines.
Biological
Foodborne Staph Toxin Pinpointed by New Assay
ARS chemist Reuven Rasooly and technician Paula M. Do built a test for staphylococcal enterotoxin A that detects the toxin at levels a billion times lower than the current gold-standard assay. It measures splenocyte proliferation and separates active from inactive toxin in chicken, beef and milk.
Biological
Salmonella spp
An FDA Bad Bug Book entry on Salmonella: a Gram-negative, rod-shaped bacterium widespread in poultry and swine, causing nausea, cramps, diarrhea and fever 6 to 48 hours after exposure, from a dose as low as 15 to 20 cells, with arthritic symptoms possible later.
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.
Biological
Two-Thirds of Broiler Chickens Contaminated: Group
Consumers Union tested 382 chickens from more than 100 retailers in 22 states and found campylobacter in 62 percent, salmonella in 14 percent and both in 9 percent, though results have improved since 2005. Cooking and separate cutting boards for poultry reduce the risk.
Biological
Water from Tualatin Valley Water District is free of E coli
Tualatin Valley Water District says its roughly 200,000 customers are not covered by Portland's boil-water notice, issued after E. coli was detected in Reservoir 3 at Washington Park.
Biological
Portland Water Bureau warns of E coli contamination in tap water - update
Portland Water Bureau told customers west of the Willamette to boil tap water after E. coli turned up in Reservoir 3 samples taken November 25. An update says water at all taps has since tested safe; the bureau reported no infections and did not identify the strain.
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.
GMO
Monsanto Pulls GM Corn Amid Serious Food Safety Concerns
Monsanto withdrew its applications for GM maize LY038 and the stacked LY038 x MON810 rather than supply the extra safety data European regulators requested, and asked for all dossier material back, putting it beyond independent review. Some scientists suspect safety, not commerce, drove the move.
Biological
Raw oysters tainted with some bacteria may pose risk
The FDA advises people with cancer, diabetes, liver disease or other immune-weakening conditions to eat oysters only thoroughly cooked, because Vibrio vulnificus thrives in warm coastal waters. The fatality rate reaches 50 percent among high-risk individuals.
Biological
Foodborne disease can cause kidney failure, paralysis
A Center for Foodborne Illness Research and Prevention report warns that a small share of food poisoning cases lead to kidney failure, paralysis, seizures or hearing and vision damage, with children, the elderly and immune-suppressed people most at risk. E. coli O157:H7 can cause HUS.
Chemical
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.
Chemical
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.
