By now, most people know they should be eating more vegetables. But are there ways to get more from the vegetables you already eat? A research shows that when it comes to vegetables, it's not only how much we eat, but also how we prepare them, that decides the vitamins and other nutrients that enter our body.

Many studies show that people who eat lots of vegetables have less heart disease, and eye problems and even cancer. But raw vegetables are not always best. The researchers found that 198 Germans who eat raw food were short of lycopene, the matter found in tomatoes and other red vegetables. "There is an idea that raw foods are always going to be better," says Steven K. Clinton, a professor at Ohio State University. "For fruits and vegetables, sometimes a little bit of cooking can be helpful."

A number of factors decide how the vegetables do good to people's health before they reach the table, including where and how they were grown and stored before being bought. No single cooking way is best. Some nutrients are easily lost in cooking if they are cooked in different ways.

Vitamins C and B are often lost. In January, another report said that boiling was better for carrots than frying or serving them raw. Frying was the worst way to cook.

What cooked with the vegetables can also be important? When the vegetables were cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them. Putting on some other things that make it taste better—a little salt—can make the food taste better.

 How to Improve your Memory

Most of us can lose our train of thought midway through a sentence but when you're a stand-up comic (单口相声演员) , it can cause disaster— as comedian Billy Connolly knows. The 70-year-old Scot admitted the fact last week, and he now suffers from worrying about memory loss on stage..His wife Pamela owes it to years of drinking in his early career.

But absent-mindedness is not just about "senior moments", says neurop sychologist Dr Iddon. "In a recent study of healthy adults, the average number of memory slips, like putting the coffee jar in the fridge, was around six per week, regardless of age, sex and intelligence," says Dr Iddon. "" Remembering is an active process and making the most of your memory involves paying better attention, planning and organising.

⒈Exercise more.

Several studies have shown that exercise is particularly good at improving memory. Exercise is also thought to encourage the growth of new brain cells in the hippocampus — an area of the brain important in memory and learning.

So if a joke is learned in the presence of a particular smell, that same smell may arouse the memory for that joke." More simply, when in an exam, I advise my students to imagine the place in which they were revising as a reminder," says Andrew Johnson, memory specialist and lecturer in psychology.

⒊Drink more milk.

Scientists asked 972 people to fill in detailed surveys on their diets and to complete eight difficult tests to check their concentration, memory and learning abilities

A. Learn more jokes.

B. Connect the memory with the environment.

C. To make matters worse, sometimes he cannot remember his lines.

D. In fact, it was the younger, busier people that were the most absent-minded.

E. Luckily, there are some strategies to help you avoid those embarrassing moments.

F. The best way to strengthen a memory is to go through the information before sleep.

G. Adults who often consumed dairy products did far better in memory tests compared with those who rarely did.
