(१)North Africa dust increase
rains in India
The amount of monsoons in India depends on the dust in North Africa, says a new study from the Indian Institute of Technology Bhubaneswar.
The dust in the air absorbs sunlight west of India, warming the air and strengthening the winds carrying moisture eastward. This results in more monsoon rainfall about a week later in India,'' said the study which appeared in Nature Geoscience on Sunday.
They weighed the mice daily and checked their glucose blood levels weekly.
Most mice that drank agavins ate less, lost weight and their blood glucose levels decreased when compared to other sweeteners such glucose, fructose, sucrose, agave syrup and aspartame.
"We have found that since agavins reduce glucose levels and increase GLP-1, they also increase the amount of insulin," said researcher Mercedes G Lopez.
GLP-1 (glucagon-like peptide-1) is a hormone that slows the stomach from emptying, thereby stimulating production of insulin.
She added "Agavins are not expensive and they have no known side effects, except for those few people who cannot tolerate them".
In addition, agavins, like other fructans, which are made of the sugar fructose, are the best sugars to help support growth of healthful microbes in the mouth and intestines, she said.
Lopez, who is a biochemist in Mexico also noted that agavins can help people feel fuller, which could help them eat less.
Lopez pointed out that, indeed, high-fructose corn syrup is loaded with fructose sugars and, therefore, can raise blood sugar levels.
But agavins are fructans, which are fructoses linked together in long, branched chains. The human body can't use them in that configuration, so they don't affect blood sugar.
Agavins also sometimes get confused with agave nectar or agave syrup, which appears on many health-food store shelves. These products contain fructans that have been broken down into individual fructoses, so they are much more similar to high-fructose corn syrup.
Also, she and her team said agavins are better than artificial sweeteners, which are absorbed by the body and can cause side effects, like headaches.
"One slight downside, however, is that agavins are not quite as sweet as their artificial counterparts," she said.
Of course, the agave's claim to fame is as the plant from which tequila is made. Lopez explained that agavins are the only carbohydrates used to produce the drink. All ethanol in tequila comes from the fermentation of glucose and fructose generated after agave pines are cooked. But because the agavins are converted to ethanol, agavins are not found in the finished product.
(5)Could a CHOCOLATE pill prevent heart attacks and strokes? Tablet containing
'healthy nutrients' goes on trial
- Scientists will study the health benefits of consuming cocoa flavanols
- They are thought to improve blood pressure and cholesterol
- They could also improve the body's use of insulin and artery health
- The researchers will trial pills containing high doses of the flavanols
- They contain more flavanols than could be gleaned from eating chocolate
The study of 18,000 people will be sponsored by the National Heart, Lung and Blood Institute and Mars.
