Walnuts & Other Nuts Improve Markers of Chronic Disease

Walnuts, almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, and pistachios are types of tree nuts, for which a number of previous studies have suggested a variety of health benefits. Carol O’Neil, from Louisiana State University Agricultural Center (Louisiana, USA), and colleagues reviewed data collected on 13,292 men and women, ages 19 years and up, participating in the National Health and Nutrition Examination Surveys (NHANES) 1999 – 2004.  The team surveyed subjects for on dietary intake – including tree nuts, and correlated the data against factors involved in chronic diseases.   Tree nut consumers had lower body weight, as well as lower body mass index (BMI) and waist circumference compared to nonconsumers.  The mean weight, BMI, and waist circumference were 4.19 pounds, 0.9kg/m2 and 0.83 inches lower in consumers, as compared to non-consumers.  Further, tree nut consumption was associated with a 5% lower prevalence of metabolic syndrome, as well as a lower prevalence of four risk factors for metabolic syndrome: abdominal obesity, high blood pressure, high fasting glucose (blood sugar) levels and low high-density lipoprotein-cholesterol levels.

Omega-3 fatty acids may improve cognitive functioning, presumably by increasing cerebral blood flow.
Testosterone supplementation improves walking, oxygen consumption, fasting glucose, and insulin, in patients with heart failure.
People with a history of mental illness are more likely to also have a chronic health condition, such as heart disease or diabetes.
People who sleep six hours or less are at increased risk having a greater body mass index (BMI).
Foods high in fiber provide good protection against cardiovascular disease, with the effect particularly pronounced among women.
Among men, one to two alcoholic drinks a day associates with lower risk of all-cause mortality, as well as cardiovascular death risk.
Eating tree nuts helps to lower body weight and body mass index, while improving cholesterol levels and markers of inflammation.
Shrinking of the hippocampal region of the brain occurs with age and may be caused by the cumulative effect of genetic factors.
Increased amount of phthalates circulating in blood may double a person's diabetes risk.
People who consume a greater quantity and variety of fruits and vegetables may cut their risk of diabetes by up to 21%.

263. Coffee Clutch
Don’t underestimate the humble cup of coffee. A European team reports that a daily cup of coffee helps to minimize the oxidative damage to DNA. Enrolling 38 men and women for a controlled intervention trial where each subject consumed 800 ml of paper-filtered coffee or water daily over 5 days. The researchers found that coffee reduced the oxidative damage to DNA, as measured by a decreased formation of oxidized purines, by 12.3%.

Among the most frequently consumed beverages worldwide, coffee is rich in antioxidants, with one cup providing 350 mg of phenolic compounds...
