D
The high-protein, low-carbohydrate(碳水化合物) diets many people turn to for weight loss might have potentially harmful long-term effects on the colon, a small study indicates.
In the study, UK researchers found that a protein-heavy, low-carb diet created certain changes in the colon that could contribute to colon cancer risk. The study itself does not show whether high-protein diets really raise the risk of any colon diseases, but the findings raise that possibility.
Diets relatively high in protein and lower in carbs have been shown to help heavy people lose weight. “People should not be discouraged from losing weight,” Dr Flint said. However, he added, they should make sure that any weight loss plan includes adequate amounts of fiber and a high protein intake over months to years might have ill effects on the colon.
The findings are based on 17 overweight men who followed three short-term diets: a one-week menu plan to keep their weight; a four-week high-protein diet with reasonable amounts of carbohydrates; and a four-week high-protein diet low in carbs.
On average, the study found when the men were on the high-protein diets, they had higher levels of substances known as N-nitroso compounds(亞硝基化合物) and other metabolites(代謝物) that have been linked to cancer. And when they were on the high-protein, low-carb diet, they had lowered amounts of fiber-originated compounds thought to be protective against cancer.
Exactly what those changes might mean for a person’s health is not clear, But Flint said that the findings suggest that people should be cautious about consuming too much protein and too little fiber over a long period. In general, experts recommend that adults get about 28 grams of fiber per day—though it’s not known whether that’s enough for someone on a high-protein weight-loss diet.

A
When Josephine Cooper was growing up, she learned the importance of charity from her parents. Although they made a modest living for their family of 10, they insisted on sharing with those less fortunate.
Half a century later, Mrs Cooper became a beloved volunteer at the San Diego Food Bank, where she devoted herself to helping others. She organized and ran a distribution center from a church, helping it become the organization’s largest emergeney fooddistribution center in San Diego. She was one of 25 outstanding senior volunteers in the nation selected and invited Washington D.C. to receive the award.
“She was the main person who helped us make that program grow,” said Mike Doody, former director of the Food Bank. “She had a way of getting people to work together and to work hard. She was determined and stubborn, but in a good way. She had a good heart.” People knew her as “Grandma” because of her selflessness and her devotion to helping hungry children and families. “She reminded people of their Grandma.” Doody said.
As a widow with a young child in 1979, Mrs. Cooper was helped through a difficult financial time when the Food Bank provided her with groceries. “She dedicated her life to giving back,” said her daughter, Monica Cooper. It wasn’t unusual for a local church to call Mrs Cooper to ask her to aid a needy family. “She would give people food out of her cupboard. Sometimes we would cook a meal for a frailly living out of their car,” Cooper said.
Although Mrs Cooper was honored to receive the national award for her volunteer work, she said being able to help others was her reward. She died of liver disease and kidney failure, aged 93.
