每天两餐西红柿 永葆肌肤年轻

At this rate, scientists will have to come up with a better description for the tomato than mere 1 'superfood'.
While it has long been credited with cutting cholesterol 2 and preventing some cancers, the fruit now appears to have two more healthgiving benefits.
Protection against sunburn and helping 3 keep the skin looking youthful are the latest pluses, a study has found.
Professor Mark Birch-Machin said tomatoes could provide a cheap and easy way of improving health.
"I went into the study as a sceptic," he added. "But I was quite surprised with the significance of the findings."
Researchers at Manchester and Newcastle universities recommend two tomato-based meals a day for optimum 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 using ultra-violet lamps showed the tomato-eaters were a third better protected against sunburn at the end of the study than at the start, the British Society for Investigative Dermatology's annual conference heard.
Other tests suggested the tomato-based diet had boosted production of collagen, the protein that keeps skin supple 4.
If that were not enough, the fruit also protects our mitochondria - the elements of cells which turn the food we eat into energy.
Professor Birch-Machin, of Newcastle University, said: "Being kind to our mitochondria 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 suncream. Professor Lesley Rhodes, a Manchester University dermatologist 5, said: "People should not think tomatoes in any way can replace suncreams but they may be a good additive 6.
The fruit's benefits are credited to lycopene, the pigment 7 behind its distinctive 8 red skin.
Lycopene, a powerful antioxidant capable of mopping up free radicals 9 - the harmful molecules 10 linked to cancer - is made easier for the body to absorb when tomatoes are cooked or processed.
