2 . Pick up any packaged processed food, and there’s a decent chance that one of its listed ingredients will be “natural flavour”. The ingredient sounds good, particularly in contrast to “artificial flavours” since there is a common belief that ingredients from nature are necessarily safer than something artificially made. But it’s not true. Then what exactly does the natural flavour mean? It refers to extracts (提取物) got from natural sources like plants, meat or seafood. When consumers see the “natural flavour” on a label, they are unlikely to assume that someone is squeezing the juice from oranges into their bottles. They know even though natural flavour must come from natural sources, it needn’t all come from the plant or meat. For example, orange flavours might contain not only orange extracts, but also extracts from bark and grass.
So if flavours like orange are needed, why not just use oranges? The answer comes down to “availability, cost, and sustainability”, according to flavour chemist Gary Reineccius of the University of Minnesota. “If you’re going to use all your grapes on grape soda,” Reineccius says, “you don’t have any grapes for wine making; the products are going to be exorbitant; besides, what do you do with the by-products you create after you’ve squeezed all the juice out of the grapes?”
Actually, while chemists make natural flavours by extracting chemicals from natural ingredients, artificial flavours are made by creating the same chemicals artificially. The reason why companies bother to use natural flavours rather than artificial flavours is simple: marketing. “Many of these products have health titles,” says Platkin, professor from Hunter College. “Consumers may be talked to believe products with natural flavours are healthier, though they are nutritionally no different from those with artificial flavours. Natural flavours may involve more forest clear-cutting and carbon emissions from transport than flavours created in the lab.”
Platkin suggests getting more transparent (易懂的) labeling on packaging that describes exactly what the natural or artificial flavours are, so consumers are-not misled into buying one product over another because of “natural flavours”. Reineccius also offers simple guidance: “Don’t buy anything because it says ‘natural flavours’. Buy it because you like it.”

3 . New research suggests tea might help those who drink it live longer than those who do not. Past studies in China and Japan, where green tea is popular, have suggested several health benefits. Now, scientists say black tea may show similar benefits.
Scientists from the United States National Cancer Institute carried out the study. They examined years of data gathered about the tea drinking behavior of almost 500,000 adults in Britain for as many as 14 years. Black tea is the most common kind of tea in Britain.
The study found that high tea intake — two or more cups a day — was linked to a moderate benefit: a 9 to 13 percent lower risk of death from any cause than non-tea drinkers.
The research was published in Annals of Internal Medicine. The scientists say the lowered risk of death held true for study subjects with heart disease. However, researchers said there was no clear finding in connection with deaths from cancer. Researchers were not sure why. “It is possible that there were too few confirmed cancer deaths to measure,” said Maki Inoue-Choi, who led the study.
Tea contains various elements, including polyphenols, which are thought to be responsible for the health benefits that have traditionally been linked to tea, especially green tea. Green tea is reported to improve mental ability, ease digestive problems and head pain, and help people with weight loss. Green tea has also been studied for possible protective effects against heart disease and cancer.
The study of British tea drinkers was based on observing people’s behaviors and health.
This kind of methodology cannot prove cause and effect.
“Observational studies like this always raise the question: Is there something else about tea drinkers that makes them healthier?” said Marion Nestle. She is a professor of food studies at New York University.
“The study does not offer enough evidence to advise people to change their tea behaviors,” said Inoue-Choi.

Sichuan Cuisine and Hunan Cuisine are both known for their hot flavors, which might appear similar at first sight. That’s why Americans are pretty confused about how they are different.
This confusion has its roots in how Hunan food
