Steven Blair of the Cooper Institute is cited saying overweight but fit people have half the death rate of normal-weight people who are unfit. The piece lists the conditions attached — no smoking, 30 minutes of daily activity, no major risk factors — and says sedentary and fit cannot mix.

Obesity
Obesity linked to advanced prostate cancer
A Cancer Epidemiology, Biomarkers and Prevention study of 84,000 men by Brenda Hernandez found those overweight or obese in young adulthood faced higher risk of advanced prostate cancer. Because it is not a trial, it cannot show that obesity causes the added risk.
Obesity
Obesity may cause "severe brain degeneration" study says
A Human Brain Mapping study of 94 people in their 70s found obese participants had 8 percent less brain tissue than those of normal weight, with losses in the frontal and temporal lobes. Senior author Paul Thompson says obese brains looked 16 years older than lean ones.

NUTRITION NOTES: Changing the Picture for Senior Cancer Survivors
Karen Collins of the American Institute for Cancer Research writes that senior cancer survivors face both second cancers and functional decline, and that weight control, moderate activity and healthy eating may cut risk and improve quality of life. Mailed and phone programs show early promise.

Einstein scientists link elevated insulin to increased breast cancer risk (press release)
Albert Einstein College of Medicine researchers report in the International Journal of Cancer that elevated blood insulin appears to raise breast cancer risk in postmenopausal women. Unlike earlier conflicting studies, theirs used repeated insulin measurements taken over several years.
Obesity
Childhood obesity: Your children are what YOU eat
A study in the International Journal of Obesity found obese mothers were 10 times more likely to have obese daughters and fathers six times more likely to have obese sons. Researcher Terry Wilkin says the gender pattern points toward learned behavior rather than genes.
Heart & Blood
Study: Virus may trigger high blood pressure
Harvard's Clyde Crumpacker found that the herpes virus cytomegalovirus causes lasting inflammation in blood vessels that over time may trigger high blood pressure, and that 30 percent of CMV-exposed mice on a high-fat diet showed atherosclerosis. He suggests antivirals may one day treat it.
Other Diseases
Allergy Awareness Week
Food allergies affect 12 million Americans, three million of them children, and the CDC reports peanut allergy among children doubled over a recent five-year period. During Allergy Awareness Week, May 10-16, allergy groups pushed for more research funding.
Obesity
Obesity climb tied directly to excessive calorie Intake
Professor Boyd Swinburn told the European Congress on Obesity that rising U.S. obesity since the 1970s traces directly to eating more calories rather than exercising less. In his analysis of 1,399 adults and 963 children, exercise still blunted the gain by about two kilos.
Heart & Blood
Fructose vs. glucose debate ignited by study
In a 10-week test of 32 obese people, those drinking fructose-sweetened beverages for a quarter of their daily calories gained the same weight as the glucose group but added more belly fat, became somewhat insulin resistant and had higher blood lipids.
Other Diseases
Sports drinks found to be corrosive of teeth
NYU dentistry researchers soaked calf teeth in Powerade, Gatorade, Life Water, Vitamin Water and Propel Fit for 75 to 90 minutes and found dozens of visible holes, while teeth soaked in water were undamaged. The beverage industry disputes that soaking reflects drinking.
Obesity
Once the weight is lost, low fat diet more appropriate
A University of Maryland study put 26 adults on Atkins, Ornish or South Beach and tracked cholesterol and blood vessel changes; LDL rose on Atkins and fell on the others. Dr. Michael Miller says that once weight is lost, a low-saturated-fat diet serves the heart best.
Obesity
Chewing gum reduces cravings for sweets
Researchers from the Pennington Biomedical Research Center and LSU reported that chewing Wrigley's Extra sugar-free gum cut afternoon snack intake by 40 calories and sweet snacks by 60, and suppressed hunger and cravings between lunch and the snack.
Other Diseases
Trans fat, saturated fat may induce cognitive decline in diabetics
Among 1,486 diabetic women aged 70 and over in the Nurses' Health Study, higher intakes of saturated and trans fat since midlife were associated with worse cognitive decline. The gap between highest and lowest trans fat intake matched about seven years of aging.
Cancer
Folic acid may boost colorectal cancer risk
Since Chile mandated folic acid fortification of flour, colorectal cancer rates rose 162 percent among people aged 49 to 64 and 190 percent among those 65 to 79, a University of Chile team reports. Critics point to obesity, smoking and heavy drinking as alternative explanations.
Obesity
Replacing soft drinks with water may equal weight loss
A Dutch study found teens who swapped sugary drinks for water did not compensate by eating more snacks. In a USC study of 54 overweight Latino adolescents, those who cut back on sweet drinks had healthier blood sugar, and many also ate more fiber and lost visceral fat.
Cancer
Drinking Hot Tea May Cause Throat Cancer
People in northern Iran who drank tea hotter than 70 degrees Celsius were eight times more likely to have throat cancer than those drinking it below 65, in a study of 300 esophageal cancer patients and 571 others. The authors suspect repeated injury to the esophagus.

Breast cancer: What you need to know
After Christina Applegate's breast cancer was found on a routine MRI, the piece reviews prevention research foodconsumer.org has covered, including a study in which female rats fed 250 mg of kelp daily lengthened their cycle 37 percent and cut estradiol 25 percent.
