A new study published in the latest issue of the British Journal of Nutrition shows that eating ketchup often plays an important role in protecting the heart. Scientists at the University of Oslo in Finland have found through experiments that tomato sauce, the British hobby, is of great help in curbing "bad" cholesterol (low-density lipoprotein cholesterol). In the study, volunteers added 30 grams of tomato sauce to breakfast, lunch and afternoon tea, or 400 ml of tomato juice a day. The researchers found that in just three weeks, the total cholesterol level of the participants decreased by 6%; while the low-density lipoprotein cholesterol level decreased by nearly 13%. Researchers have called for high-cholesterol patients who want to reduce the risk of heart disease and stroke, so eat more tomato sauce or tomato juice.
