What's the secret of eternal youth? Please try a tomato! At this rate, scientists will have to come up with a better description for the tomato than mere "super food".While it has long been credited with preventing some cancers, the fruit now appears to have two more healthy-giving benefits. A study has found that tomatoes have got protection against sunburn and help keeping the skin looking youthful. Tomatoes could provide a cheap and easy way of improving health. Researchers recommend two tomato-based meals a day for health. Possible menus include a glass of tomato juice with breakfast and a salad later or tomato soup for lunch and pasta with a tomato sauce for dinner. To test the fruit's ability to protect the skin, ten volunteers were asked to eat five tablespoons of tomato paste mixed with olive oil every day for three months. Another ten had a daily dose of olive oil—minus the tomato paste. Tests showed the tomato-eaters were a third better protected against sunburn. Other tests suggested the tomato-based diet had increased production of collagen, the protein that keeps skin supple. If that were not enough, the fruit also protects our elements of cells which turn the food we eat into energy. The fruit is likely to contribute to improved skin health, which in turn may have an anti-ageing effect.The researchers stressed, however, that their findings were not an excuse to throw away the sun cream. People should not think tomatoes in any way can replace sun creams.1.What is the main idea of this passage?A) How tomatoes are different from other fruits.B) The positive and negative functions of tomatoes.C) The various uses of tomatoes.D) How tomatoes can make people healthy and young.2.According to the researcher, how many tomatoes a day will be healthy?A) Two tomato-based meals a day.B) One for each meal.C) Two for each meal.D) One tomato-based meal a day.3.Which is NOT the effect of tomatoes?A) They can protect skin against sunburn.B) They can be turned into energy.C) They can improve skin health.D) They can have an anti-ageing effect.
