CNIO researchers cut young mice's calorie intake by 40 percent and followed them for life, reporting slower telomere shortening, longer telomeres in adulthood, fewer chromosome anomalies and a lower incidence of cancer and other age-related illness.

Binge drinking can dramatically amplify damage to the liver (PR)
A review in Alcoholism: Clinical & Experimental Research finds binge drinking alters several cellular components and dramatically amplifies liver injury in livers already exposed to chronic alcohol. Shivendra Shukla notes liver damage can have a domino effect on other organs.

Gluten free diet helps fight type 1 diabetes mellitus
A case report describes a boy of five diagnosed with type 1 diabetes who went on a gluten-free diet and stayed off insulin for 20 months, with HbA1c settling at 5.8 to 6.0 percent. His diabetes-associated antibodies did not change; the authors call it a prolonged remission.

Diet plays a role in irritable bowel syndrome
Among 193 Romanians, those who more often ate canned food were nearly 24 times as likely to have irritable bowel syndrome, with processed meat, pulses, whole cereals, confectionery, fruit compotes and herb teas also tied to raised odds. Older age and past digestive disease also featured.

Low-Fat Diet Better for Type 1 Diabetes Control
Joslin Diabetes Center researchers found that people with type 1 diabetes run higher blood sugar after high-fat meals and need more insulin, which suggests watching fat as well as counting carbohydrates. The PCRM note says cutting fat may lower insulin needs.

Vegan Diets Have Lower Cancer Risk
Researchers tracked the diets of 69,120 Adventist Health Study-2 participants for more than four years and found vegans had a 16 percent lower risk of all cancers. Vegan women had a 34 percent lower risk of breast, ovarian and uterine cancers than nonvegetarians.

Heart disease news: Prudent diet prevents heart disease, stroke
Among 40,011 Dutch adults followed 13 years, the top quartile for a prudent diet of fish, high-fibre foods, raw vegetables and wine had 13 percent less coronary heart disease and 22 percent less stroke than the lowest quartile. A Western diet pattern showed no link to either.

Yes, Cutting Fatty Foods Really Does Help You Lose Weight
A BMJ review of 43 studies covering more than 180,000 people in developed countries found that the lower the fat intake, the lower the body mass index, waist size and total cholesterol, and the greater the weight loss.

Low fat diet cuts breast cancer risk
Mice bred to develop mammary tumors and fed a fatty-acid-free diet developed breast cancer less often, later and in smaller numbers than mice on a standard diet, though tumor growth rate was unchanged. The work was done in mice, not people.
Diet
Drinking alcohol boosts breast cancer death risk
Among 1,052 Danish women with early breast cancer, those drinking more than two units a day at baseline were 65% more likely to relapse over six years than those drinking under one unit. Drinking for more than 40 years doubled recurrence risk.
Diet
A simple way to prevent cancer, heart disease, diabetes
A Public Health Nutrition review by Queen's University Belfast researchers found vegetarian diets and diets with only small amounts of red meat correlate with lower rates of coronary heart disease and type 2 diabetes, with some evidence pointing to cancer prevention as well.

Hypertension linked to insomnia, some nutrients help sleep quality
In 5,747 Japanese workers averaging 43.8 years old, those with hypertension more often had insomnia, and those with insomnia more often had hypertension. Many never raised it with a doctor, relying on nightcaps or over-the-counter drugs instead of treatment.

Poor diet linked to ADHD symptoms
Researchers analyzing data on 11,676 German children and teens found poor dietary quality associated with parent-rated hyperactivity and inattention scores, most strongly in girls. They concluded poor nutrition, high energy intake and television time appear independently linked to ADHD symptoms.
Diet
Dietary pattern identified to prevent Alzheimer's disease
Following 2,148 dementia-free New Yorkers aged 65 and over for 3.8 years, Columbia researchers found those adhering most closely to a pattern high in salad dressing, nuts, fish, tomatoes, poultry, cruciferous vegetables, fruit and leafy greens were 38% less likely to develop Alzheimer's.

High fat diet may hurt type 2 diabetics
Using PET imaging, researchers found overweight and obese people with impaired glucose tolerance took dietary fatty acids into heart muscle at a higher rate in the six hours after a meal, alongside reduced stroke volume and ejection fraction and impaired diastolic function, a Diabetes study reports.
Diet
Vegetarians Live Longer
Early findings from the Adventist Health Study-2, which follows more than 96,000 people, put vegetarian men's average lifespan at 83.3 years against 73.8 for nonvegetarian men, and vegetarian women's at 85.7 years, 6.1 years longer than nonvegetarian women.
Diet
Not all Mediterranean diets prevent breast cancer
A French case-control study found no overall link between Mediterranean eating and breast cancer. A fish-heavy version tracked with 23 percent lower risk, while a raw-vegetables-and-olive-oil pattern tracked with 22 percent higher risk and a meat/alcohol pattern with far higher risk.

Healthy diet makes better sperm
Among 188 men aged 18 to 22, those eating most of a "Prudent" pattern of fish, fruit, vegetables, chicken, legumes and whole grains had 11.3 percent more progressively motile sperm than those eating least. No link appeared with sperm count or shape, or with a Western pattern.
