The piece gathers evidence that aerobic fitness protects the aging brain: a 2004 National Academy of Sciences study found greater prefrontal and parietal activity in fit participants, and a six-month Beckman Institute study of 124 adults found better executive-control performance.

Calorie restriction induces weight loss, boosts insulin sensitivity
In a trial of 63 sedentary adults with metabolic syndrome, 12 weeks of calorie restriction produced a 7.6 percent weight loss and a 49 percent improvement in insulin sensitivity; adding aerobic exercise gave 9.1 percent weight loss and a 45 percent insulin improvement.

Healthy lifestyle prevents dementia like Alzheimer's
Among 3,468 Japanese-American men followed from midlife in Hawaii, those who avoided smoking, kept BMI low, stayed active and ate well were 63 percent less likely to develop dementia overall. For Alzheimer's alone, none of the four habits reached significance.

Dietary weight loss protects the heart in obese women
In a small trial, 35 overweight or obese non-diabetic women lost as much as 6.0 kg over six months of calorie restriction and showed 26% less myocardial triglyceride, which the authors treat as a marker of impaired cardiac function. Fat-restricted and carbohydrate-restricted diets performed alike.

Healthy lifestyle helps prevent dementia - study
In the Honolulu-Asia Aging Study of 3,468 Japanese-American men, those who avoided smoking, stayed lean, exercised and ate well in midlife were 63 percent less likely to develop dementia overall. Body mass index showed the strongest link; none of the four factors tracked Alzheimer's alone.

Corrected: Mutation determines how tobacco smoking affects colorectal cancer risk
Among 1,233 Iowa women with colorectal cancer, smoking measures such as starting age, cigarettes per day and pack-years were linked to KRAS mutation-negative tumors but not mutation-positive ones. Women smoking 40 or more a day had 2.38 times the risk.

Tobacco smoking raises gastric cancer death risk
Among 699 patients who had curative surgery for gastric cancer, current and former tobacco users were 43 percent more likely to die of the cancer and 48 percent more likely to die of any cause than never-smokers. The study was not a trial, so it cannot establish cause.

Tobacco use and lung cancer deaths
A Journal of the National Cancer Institute study estimates US tobacco control averted 795,851 lung cancer deaths from 1975 through 2000, including 70,218 in 2000 alone. That is only 32 percent of what eliminating tobacco use entirely could have prevented over the period.

Male circumcision can lead to loss of sexual pleasure - study report
In a survey of 5,552 men and their spouses, circumcised men reported frequent orgasm difficulties more often than uncircumcised men, 11 percent against 4 percent. Women with circumcised spouses also more often reported unmet sexual needs, orgasm difficulty and pain.

Weight loss helps in vitro fertilisation
An Adelaide trial randomized overweight women to a lifestyle program or standard care before in vitro fertilisation. The lifestyle group lost more weight while the standard group's weight did not change; both cut waist circumference, and 53 percent of the women overall became pregnant.

Aborted pregnancy boosts breast cancer risk - study
A case-control study of 668 breast cancer patients and 682 controls in Jiangsu, China linked induced abortion to higher breast cancer risk: after adjustment, 55 percent higher in premenopausal women with three or more, and 82 percent higher in postmenopausal women who had one.

Cigarette smoking raises overt albuminuria risk in female type 1 diabetes patients
Among 259 Japanese patients treated for type 1 diabetes, women who currently smoked were about four times as likely as non-smokers to have overt albuminuria. The authors say this cross-sectional result suggests smoking might be a risk factor in female patients.

Tobacco a major killer
Researchers in Tbilisi estimate smoking caused about 10% of all deaths in Georgia in 2008, including 30% of cancer deaths and 10% of cardiovascular deaths. CDC puts the U.S. toll at 443,000 deaths a year, or 20% of all deaths.

New Insights into Links Between Immune Function and Sleep
Mercola reports on a study in Sleep in which 15 people stayed awake 29 hours and their white blood cell counts rose, the same response the body mounts to illness or physical stress. Related work in Nature examined how neutrophils power inflammation.

Consumption of Cigarettes and Combustible Tobacco — United States, 2000–2011
CDC estimates drawn from federal excise tax data show total combustible tobacco consumption fell 27.5% from 2000 to 2011, while loose tobacco and cigar use rose 123.1%, lifting their share of the total from 3.4% to 10.4%.

Obesity Surpasses Smoking in Terms of Ill Health Effects
Data from more than 60,000 Canadians indicate obesity drives more doctor visits than smoking, with the study estimating visits would fall 10 percent without it. Researchers suggest the finding could prompt insurance penalties, complicated by obesity's concentration among low earners.

Tobacco Users More Likely to Die from Gastric Cancer
Among 699 patients who had curative surgery for gastric cancer at Memorial Sloan-Kettering, those who had ever smoked more than 100 cigarettes were about 1.45 times as likely as non-users to die of the disease. Both heavy and light use tracked with worse survival.

Breastfeeding cuts risk of epithelial ovarian cancer
Comparing 881 women who breastfed with 1,345 who did not, Jordan's team found ever breastfeeding matched a 22 percent lower risk of epithelial ovarian cancer, rising to 44 percent among women who breastfed for 18 months. The reduction was greatest for endometrioid and clear cell subtypes.
