JUNK FOODS LEADS TO OBESITY.

                            A study has found that eating too much fatty junk food destroys the brain cells that control weight, leading to a vicious circle of obesity. Researchers fed rats what they described as a “typical high-fat American diet” and found they had doubled their calorie intake three days later. It also showed they had an inflammation in the hypothalamus, the part of the brain containing neurons that control body weight, and though the inflammation stopped a few days later, it recurred after four weeks.

NEW DEVICES TO DETECT MEAT ADULTERATION.

                    
                     Food safety Inspectors in the United Arab Emirates have started using new devices to detect meat adulteration.The devices, being used during inspections of butcheries and meat shops, check for impurities and ensure that the meat on sale is free from adulteration.(Thanks: Gulf News).
                 One such device, using laser technology, measures the meat's internal heat and is helping inspectors prevent frozen meat from being sold as fresh.That too,this need not be brought in direct contact with the meat, thus avoiding any resultant contamination. Similarly, there are devices that accurately measure the moisture and acidity levels in the meat.Another device measures the fat content in meat, picking out discarded meat parts from good chopped or cut meat.

                     Some meat-sellers mix discarded meat parts with good chopped or cut meat to increase profits. In such cases, detecting the levels of fat in meat, fish or poultry products will reveal manipulations easily.An average of eight readings shown on the device provides clinching evidence against manipulations.
