Article: Girls who get enough dairy products in their diets may weigh less than other teens with the same age. Girls who consumed more dairy products were found to have slimmer middles than girls of the same age and race who ate the same number of calories and got the same amount of exercise. Girls who drank more soda, but also ate the same total calories, tended to be heavier. The newly reported study included 323 white and Asian girls between the ages of 9 and 14. A number of studies, mostly in adults, have shown that calcium may be key in maintaining normal body weight and fat stores. One reason may be the nutrient's effects on hormones that help store calories as fat. In the new study, reported in the Journal of Nutrition, calcium from dairy sources, but not non-dairy foods, was related to lower weight and less abdominal fat--the link was particularly strong among girls of Asian decent , who made up 47 percent of the study group. This suggests that "the dairy ingredient of the calcium intake is the key factor," write the study authors, led by Dr. Rachel Novotny of the University of Hawaii in prefix = st1 /Honolulu. It's possible, they explain, that other nutrients in milk play an important role in weight balance. For reasons that are unclear, the effect on body fat was stronger for Asian girls than for white girls, according to Novotny and her colleagues. They _ that ethnic differences in which dairy products are usually consumed, or in eating habits-having small amounts of dairy throughout the day, for instance, rather than a single large serving--may help explain the finding. According to the researchers, soda may increase pounds by adding calories to kid's diets, or by replacing milk. Milk, they note, has a range of nutrients, including protein and fat, which means it is metabolized ly slowly. Soda contains only sugar, which is quickly metabolized, easily causing hunger.
Answer: Dairy Products Build Slimmer Bodies in Girls

Article: It's not uncommon in America for a person to belong to some kind of volunteer group. Donating one's time and services is very much a part of the American way of life. Most charitable activities are organized by churches and groups around the nation and even encouraged by the government. The helping hand is extended to the poor, the homeless and the disabled. Some people work to teach youngsters how to read. Others open up soup kitchens to feed the homeless. Volunteers also take care of the disabled by making reading tapes for the blind and working in orphanages to help children without parents. High school students are often encouraged to become volunteers and many school club activities center around volunteer services. Students may work with disabled children during a summer program, or participate in a club activity which helps to bring meal to senior citizens who are shut-ins. With their sense of idealism students are often eager to donate their spare time. They see such activities as a way of becoming involved in the community and the adult-world. Social action for them becomes as important as their academic studies. In a like manner, throughout the year,fund raising drives are also conducted by schools and community groups to raise money for a worthy cause. They may respond to a recent earthquake in a foreign country, a flood somewhere within their own, or another natural disaster which has left people destitute and homeless. They may organize drives to collect food, clothing and medicines to serve an immediate need. Today even the Halloween custom of 'trick or treat'has become an occasion to collect money for a charitable cause. The motive to help those less fortunate comes from the poor origins of the American nation. Those immigrants who were poor and downtrodden became dependent on the kindness of their neighbors to make a new life for themselves. American volunteers work throughout the world in less developed countries. They volunteer by serving as a champion of goodwill both at home and abroad, which no doubt enriches both his life and those whom he serves.
