Weight-Loss Surgery Now Most Effective Against Type 2 Diabetes

Obesity, a worldwide problem that is growing, is the central topic at a world-wide conference of bariatric surgeons this Labor Day weekend. The use weight-loss surgery to treat Type 2 diabetes will dominate the data presented.

The secret to fish oil’s anti-inflammatory properties

Fish oil is touted for its anti-inflammatory and anti-diabetic benefits, but scientist weren’t sure how the omega-3 fatty acids in fish oil work. Now, according to a report in the September 3rd issue of the journal Cell, scientists have nailed how omega-3 fatty acids both shut down inflammation and reverse diabetes in obese mice.

New evidence that fat cells are not just dormant storage depots for calories

Scientists are reporting new evidence that the fat tissue in those spare tires and lower belly pooches — far from being a dormant storage depot for surplus calories — is an active organ that sends chemical signals to other parts of the body, perhaps increasing the risk of heart attacks, cancer, and other diseases.

Vitamin C: Stress Buster

A study finds in addition to benefits related to the common cold and cancer, vitamin C helps reduce both the physical and psychological effects of stress on people.

Your enlarged aorta – The Heart Scan Blog

Factors that weaken the aortic wall–Processes like inflammation, glycation, lipoprotein deposition, and nutritional deficiencies will serve to weaken the supportive tissue of the aorta. For that reason, correction of lipoprotein abnormalities (e.g., small LDL and lipoprotein(a)), reductions in carbohydrate intake and thereby blood glucose/glycation, and "normalization" of vitamin D, vitamin C supplementation (for collagen crosslinking), and omega-3 fatty acids all play a role.

Caffeinated chewing gum increases repeated sprint performance and augments increases in testosterone in competitive cyclists.

Following caffeine treatment, testosterone increased by a further 12 +/- 14% (ES 0.50; +/- 0.56) relative to the placebo condition. In contrast, cortisol concentrations were not elevated until after the third exercise set; following the caffeine treatment cortisol was reduced by 21 +/- 31% (ES -0.30; +/- 0.34) relative to placebo. The acute ingestion of caffeine via chewing gum attenuated fatigue during repeated, high-intensity sprint exercise in competitive cyclists. Furthermore, the delayed fatigue was associated with substantially elevated testosterone concentrations and decreased cortisol in the caffeine trials.
