New research has found that eating regular balanced meals is more effective (有效的) in managing a healthy weight dieting.
Carried out by researchers at the University of Helsinki, the study looked at 2,452 women and 2,227 men, who (ask) to answer surveys which looked at factors (因素) influencing weight changes at age 24, and ten years later at age 34.
The researchers found among both men women, irregular eating and dieting in order to lose weight were two of the main factors that led to weight increasing. A woman's risk of putting on weight was also increased by giving birth to two or more (child), regularly drinking sugary drinks and feeling (disappoint) with life. For men, smoking was another important factor for putting on weight.
(usual), people try to prevent overweight by dieting. In the long term, it seems to make people (get) fatter, rather than prevent it.
Besides eating regularly and avoiding diets, physical activity was a main factor in (help) to protect women from putting on weight, while for men a higher level of (educate) and having a greater weight at the beginning of the study appeared to have a protective effect.
The researchers suggested that those want to keep a healthy weight long-term should now consider eating regular meals.
What's your opinion on spicy food? Some people cannot handle even the smallest amount of the chili (辣椒) in their dinner while others can't get enough of it.
Scientists have long been puzzled by why some people love chilies while others loathe them. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chilies is related to childhood experiences, and cultural influences affect our taste buds, too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.
"We have always assumed that liking drives intake——we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits (特点) with the intake of chili peppers," said Professor John Hayes from Pennsylvania State University, who led the study.
But before you look at the study, you should first know that "spicy" is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrills, something they usually get from watching action movies or riding a roller coaster.
In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personalities, for example, whether they like new experiences or tend to avoid risks. They were then given cups of water with capsaicin, the plant chemical that makes chilies burn, mixed into them.
By comparing the answers to the questionnaires and what participants said they felt about the spicy water, researchers found that those who were most tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.
Interestingly, we used to believe that the reason why some people can withstand spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise. "It's not that it doesn't burn as badly, but it's that you actually learn to like the burn," explained Hayes.
There is a disease sweeping (迅速传播) the world today is killing far more people than any other, including AIDS and SARS. That disease is obesity. The World Health Organization (WHO) stated that of the 56. 5 million (death) per year around the world, over 50 percent (cause) by diseases connected unhealthy diets and lack of exercise, and that many of these could have been prevented (full). In the face of these (shock) statistics, the WHO announced plan to fight obesity. It invited governments around the world (join) in the campaign to encourage its citizens to adopt a sensible diet and to take up some forms of physical activities. As part of (it) plan, the WHO asked governments to consider the bad effect of food advertisements on (encourage) people to eat unhealthy food.
Five Tips for Safe Running
We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.
Running is good exercise, but it can be hard on the body.
Take it easy. Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too bad. The body needs time to get used to increases in distance or speed.
Listen to your body. Most running injuries do not come unexpectedly. They may include body aches, sore muscles(肌肉酸痛) and pain that does not go away.
There is no single best shoe for every runner. You should find the shoes that offer the best fit and support for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.
Take good notes. Take time after each run to write down what you did and how you felt. Look for patterns, things that happen over and over again. These notes will help you find the best exercise for you.
Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say swimming, yoga, and riding a bicycle are good exercises to combine with running.
A. Get good running shoes.
B. Usually, there are warning signs.
C. Running may also help you live longer.
D. These exercises are easier on the body.
E. Muscles and joints (关节) need time to recover.
