Why Giving Feels Good - Your Charitable Brain

Tuesday, June 19th, 2007

nico_11caudate.jpgThat good feeling you get by writing a check to your favorite charity could be your brain patting itself on the back, writes Robert Mitchum of the Chicago Tribune while reporting on a recent study published in the journal Science.

"Economic models would suggest "only Bill Gates or Warren Buffett should be making contributions, and everyone else should just free-ride," said one of the authors, economics professor William Harbaugh. "But that doesn't happen; there's high participation, where even low-income people are giving away a portion of their income."

In the study, female college students were given $100, then told either that a mandatory transfer would go from their account to a local food bank or that they could make a voluntary donation to the same charity. At the end of the study, the women were allowed to keep the remainder of the money.

Using MRI, the investigators found that both mandatory and voluntary transfers increased activity in brain areas called the nucleus accumbens and the caudate nucleus. These areas have previously been associated with the brain's response to rewarding stimuli, such as taking street drugs or viewing pictures of loved ones. The reward reaction was more intense with the voluntary giving.

In the Oregon study, not all brains showed an equal tendency toward generous behavior. Test subjects whose reward centers reacted more strongly to receiving money were less willing to make donations. "The brain is directly telling us, 'I like the food bank more than I like me,' or the other way around and can tell you who's going to give," said Colin Camerer, economics professor at the California Institute of Technology. "That's pretty cool."

Paul Zak of the Center for Neuroeconomics Studies at Claremont Graduate University, commented, "Economists have always been shocked [by unselfish altruism], and now we have a reason for it: It feels good to do this." But Zak wisely warned against drawing broad conclusions based upon this limited sample. "They picked female college students in Eugene, Ore., a very politically liberal place in which students have money, and are giving to a food bank -- who cannot like that? If I go to Tennessee and say the donation is going to an abortion clinic, it's a whole different ballgame."

Tasting the Blend: Jasmine Green Tea

Sunday, June 10th, 2007

There are a large variety of green teas that are available for you, all which have been crafted together in the quest to find alternate flavors with the same health benefits. When one is looking into the different types of teas, it can easily be seen that the combinations that have been made are to create a blend that provide you with the perfect taste. One of the blends that have become popular with this concept is Jasmine Green Tea.

The Jasmine Green Tea that is used comes from a blend of natural sources that are used to create an alternate flavor. This begins with the green tea of Pouching, which is an ancient Chinese blend. This is then combined with Jasmine flowers, which are known for their sweet flavor, as well as their fragrance that adds to the overall effects of the tea.

Typically, the green tea will be blended and made before the Jasmine is added into it. The Jasmine petals that are used will be picked off the flower and stored overnight in a cool place. This helps to bring out the flavor and the fragrance of the flowers. While the flowers are cooling, they are able to bloom, which helps to bring out the scent of the flower, providing for a better mixture of the tea. The quality of the Jasmine Green Tea will then be mixed together. Its quality is based on the fragrance and the sweetened taste that it produces from this mix.

Not only does the Jasmine Green Tea gain its mixture from the cooling and processing that is used, but can also be divided into grades because of the procedure that is used. Because the quality of the grade is based on the fragrance and the taste of the green tea, several will divide the categories by sampling the scent and taste. It is known that the higher grade Jasmine Green Teas will take the process of cooling and mixing a step further. For any higher grade Jasmine Tea, the petals that are used will be absorbed and cooled up to seven times in order to produce the flavor that is desired.

Not only will the Jasmine Green Tea be re-blended for a higher fragrance and flavor, but different types of Jasmine can be added in to create an alternate flavor. There are over 200 species of Jasmine flowers that are known, all coming in the form of shrubs or vines. The different types of Jasmine are divided by the region in which they grow, as well as the colors of the petals. However, it has been noted that each of the types of leaves will produce an alternate flavor, dependent on the species.

Like with other Green Teas, Jasmine tea is one of the ways in which those who process the teas work towards finding the perfect blend. Through the process that is used, as well as the variations that are provided, Jasmine Green Tea is able to produce a fragrance and flavor that gives one a drink of sweetness.
