A
The idea that eating fruits and vegetables will cut one’s appetite did not work out in a new study; in fact, adding fruit juice before meals boosted (增强) hunger and weight gain for some participants.
Eating apples and grapes before lunch helped people feel fuller and eat slightly less than when they drank an amount of fruit juice as an appetizer in the experiment. However, putting volunteers on a fruit- and vegetable-heavy diet for months made no long-term difference in their asssments of their own hunger and fullness, rearchers found.
Some doctors have hoped that encouraging people to eat greater volumes of fruits and veggies might help them feel full for longer and prevent overeating and weight gain. But the new study suggests loading up with more carrots and oranges every day won’t stop hunger
over the long run. The findings follow results from the same trial showing 34 participants, some overweight, some a healthy weight, gained between 3.5 and 5 pounds when they were given eight weeks of fruit juice to be added to their diet.
“If you tell people to add anything to their diet, you’re going to potentially have no weight loss, even with fruits and vegetables,” said Barbara Rolls, chair of nutritional sciences at the Pennsylvania State University in University Park.
That’s especially true for drinks, she said, since the body regulates hunger and thirst differently — and people will not eat less to make up for juice or other calorie-filled drinks.
Richard Mattes from Purdue University in West Lafayette, Indiana, and his colleagues found that when they fed volunteers a regular lunch, they ate an average of 785 or 821 calories of it, depending on the day. When the same participants started a meal with fresh and dried fruit, and then went on to the main cour, they ended up eating 678 calories of lunch, the fruit cour included. When they started with fruit juice instead, the volunteers took in a total of 891 calories.

There was a time in my life when beauty meant something special to me. I guess that would have been when I was about six or ven years old. I would get up every morning at the orphanage (孤儿院), make my bed and go to breakfast with the other twenty or thirty boys who also lived in the same dormitory.

After breakfast one Saturday morning I returned to the dormitory and saw the hou parent (宿舍管理员) chasing the beautiful butterflies who lived by the hundred in the bushes around the orphanage. I carefully watched as he caught the beautiful creatures, one after another, took them out from the net and then stuck straight pins (别针) through their head and wings, pinning them on a heavy cardboard sheet. How cruel it was to kill something of great beauty. I had walked many times out into the bushes, all by mylf, just so the butterflies could land on my head, face and hands so I could look at them up clo.
When the telephone rang the hou parent laid the large cardboard paper down on the back step and went inside to answer the phone. I walked up to the cardboard and looked
at the butterfly he had just pinned to the large paper. It was still moving about so I reached down and touched it on the wing causing one of the pins to fall out. It started flying around and trying to get away but it was still pinned by the other wing with a straight pin. Finally its wing broke off and the butterfly fell to the ground and just trembled. I picked up the torn wing and the butterfly. I tried to make it stick back on so it could fly away before the hou parent came back. But it would not stay on the butterfly.中国武术散打

He picked up the cardboard paper and started hitting me on the head. There were all kinds of butterfly pieces going everywhere. He threw the cardboard down on the ground and told me to pick it up and put it into the garbage can. Then he left. I tried to fit all the butterfly pieces back together so I could bury them whole, but it was too hard. So I put them into an old shoe box and buried them in the bottom of the bushes.
