Green tea may help fight against obesity - Pakistan Observer
Mice that were fed Epigallocatechin-3-gallate — EGCG — a compound found in most green teas, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG.
"Our results suggest that if you supplement with EGCG or green tea you gain weight more slowly," said Joshua Lambert, assistant professor of food science in agricultural sciences.
In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 percent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption, according to Lambert.
"There seems to be two prongs to this, first, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat," he said.
The findings were reported in the current online version of Obesity.
A "super broccoli" believed to help ward off heart disease and cancer has gone on sale in the UK. Developed by British scientists using conventional breeding techniques rather than genetic engineering, the vegetable looks the same as normal broccoli but contains boosted levels of a health-giving nutrient.
Research suggests the plant chemical, glucoraphanin, may protect the body against heart disease and some types of cancer.
The new broccoli, called Beneforte, contains two to three times more glucoraphanin than standard broccoli.
The nutrient is converted in the gut into the bioactive compound sulphoraphane, which circulates in the bloodstream.
Evidence indicates that sulphoraphane has beneficial effects such as reducing chronic inflammation, stopping uncontrolled cell division associated with early-stage cancer, and boosting the body's antioxidants.
Compared with normal broccoli, eating Beneforte broccoli raises sulphoraphane levels two to four times.
"Our research has given new insights into the role of broccoli and other similar vegetables in promoting health, and has shown how this understanding can lead to the development of potentially more nutritious varieties of our familiar vegetables," a newspaper quoted Professor Richard Mithen, from the IFR, as saying.
"Now there will also be something brand new for consumers to eat as a result of the discoveries we have made," he added. Female mosquitoes target humans by cueing in on the carbon dioxide (CO2) and body odour they release, causing malaria, dengue and yellow fever.
Experiments conducted by two entomologists from the University of California, Riverside have shown how female Aedes aegypti — that transmit yellow fever and dengue — respond to plumes of CO2 and human odour.
They reported that puffs of exhaled CO2 first attract these mosquitoes, which then proceed to follow a broad skin odour plume, eventually landing on a human host, the Journal of Experimental Biology reports.
