| People who want to maintain a healthy weight over time shouldn't worry about their fat intake (摄入), new research shows. The percentage of calories (卡路里) that a person got from fat had nothing to do with how much weight he/she gained, the research team found. The kinds of fat they ate didn't matter either, Dr. Nita Forouhi of the Institute of Metabolic Science, Addenbrooke's Hospital, Cambridge, UK and her colleagues found. The findings show that it is more important to aim for a healthy lifestyle including a balanced healthy diet and regular physical activity than to focus on fat intake alone as a factor (因素) in weight gain. Forouhi and her team note the role of dietary fat content in obesity (肥胖) and weight gain is still controversial To investigate, they looked at data on nearly 90,000 men and women from six different countries. They were followed for up to 10 years. Average fat intake ranged from 31.5 percent to 36.5 percent of total calories. On average, people gained about a quarter of a pound every year. But analyses found no relationship between how much weight people gained and how much fat they ate. The findings shouldn't be seen as showing that people can eat as much fat as they want. Forouhi said, "That would be absurd, considering so much evidence that already exists on the potential harms of diets high in fat for heart health for instance." In the US, she added, dietary recommendations state that people should maintain a fat intake that is 20 percent to 35 percent of total calories, and eat "healthy" fats from fish, nuts, and vegetable oils instead of "unhealthy" fats. 1.
