No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easy-to-swallow pill that you were told might prevent strokes(中风) and heart attacks you would probably be putting in an order tomorrow.
Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene (番茄红素) which makes tomatoes red and is known to break down fat in the vessels(血管). A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre-existing heart conditions. It also increased the flexibility(灵活性) of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease-responsible for 180,000 deaths a year, and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis(关节炎), diabetes(糖尿病) and even slow the progress of cancer.
Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean-style diet rich in tomatoes fish, vegetables, nuts and olive oil can significantly reduce cholesterol(胆固醇) and help prevent cardiovascular disease.
Preliminary (预先的) results from a two-month trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide(氧化氮), the gas which causes the enlargement of the vessels in response to exercise.
Ian Wilkinson, head of Cambridge University’s clinical trials unit, said “These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes.”
Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterol-lowing drugs.
Mike Knapton, head of the British Heart Foundation, said, “Although this showed lycopene improved blood flow in people with heart disease, that’s a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables.”
