The nutritional value of tomatoes has been affirmed by people. In the United States, tomato juice has become the second largest juice drink in the United States with its unique nutritional value and medical efficacy. Health-conscious Americans wake up in the morning to drink two things, the same milk, and the tomato juice. Before I go to bed, I also drink two things. I also make milk and the other is tomato juice. It can be seen from the popularity of tomato juice.
Why tomato is so attractive? The original tomato contains the same special nutrients - lycopene.
Lycopene is one of more than six hundred kinds of carotenoids in nature. It is an acyclic carotenoid. However, lycopene has the ability to remove singlet oxygen, but it is beta carotene. Times, 100 times stronger than vitamin E. Because it is impossible to make lycopene in the human body, it must be obtained from the diet.
In fact, many fruits are rich in lycopene, especially red meat fruits, such as pink grapefruit, almonds, cinnamon, papaya, red meat watermelon, etc. have a considerable content of lycopene, but tomatoes are still the best source . According to the survey, the lycopene content per 100 grams of fresh tomatoes is about 0.88 to 4.2 milligrams, and the more reddish the more mature tomatoes, the higher the pink grapefruit is also 3.36 milligrams and the pomegranate is five. Point four milligrams, red meat watermelon is 4.9 milligrams.
Lycopene can resist oxygen and prevent cancer. After a recent new era of healthy drinks, red whirlwind swept through the store. In March 1997, the "American Health Foundation" held an international seminar in New York to discuss "the efficacy of tomato and tomato products in preventing cancer." Famous experts and scholars from all over the world have enthusiastically discussed the main carotenoids in tomato and tomato products, namely the contribution of lycopene to human health.
The research team led by many experts and scholars, through epidemiological surveys and in vitro experiments, has confirmed that lycopene can help prevent the occurrence of multiple types of cancer, including prostate, breast and colon cancer, rectal cancer, and gastric cancer. And so on, and can reduce the risk of cardiovascular disease. Women who regularly drink tomato juice have a 1/3 chance of suffering from cervical cancer. Drinking lycopene in tomato juice at the same time is also a nemesis of male prostate disease.
Indian researchers have also recently discovered that lycopene helps improve male infertility. Lycopene in tomatoes can increase the number of sperm in infertile men. The National Medical Association of India conducted research on 30 infertile men aged 23 to 45 years. Researchers say that these infertile men have low levels of lycopene, so they are given oral 2 mg lycopene twice a day for three months.
Three months later, the number and motility of sperm in these men were significantly increased, and 6 more couples were successfully conceived, confirming that there is a direct link between the Lycopene index and infertility. Researchers said that oral lycopene therapy does appear to have a good effect on unexplained infertility.
While improving human immunity, preventing cancer, and activating cells, lycopene can also delay aging, skin care, and weight loss. Its highly effective anti-oxidant action can eliminate free radicals that cause aging in the human body, help prevent UV rays, reduce skin pigmentation, and help skin balance moisture and oil secretion.
Tips for eating tomatoes
There are tips for eating tomatoes.
In the United States, Dr. Kerr Dow HJ made a study on the absorption of lycopene in the human body. He concluded that the intake of lycopene-rich foods such as unprocessed tomatoes does not change the concentration of lycopene in plasma. After ingestion of heat-treated products, the content of lycopene in plasma increased by a factor of three. This is because the lycopene of raw tomato may be trapped in the matrix, and the cell wall ruptures after heating, which weakens the binding force between lycopene and the tissue matrix and thus dissolves lycopene.
Therefore, it is better to eat tomatoes as they are eaten raw. It is better to eat tomato juice when cooked.

The chair side CAD / CAM repair system has obvious advantages in aesthetic effect, operation time, patient participation and operation convenience. Discussion: traditional repair method: after the model is transferred, it will be sent to the technician's room for processing and making the final prosthesis. About one week, the final prosthesis will be tried on, grinded and bonded. The prosthesis was made in the technician's room. The patients need to accept the aesthetic effect of the prosthesis passively without any sense of participation. The implant repair method of chair side CAD / CAM system: obtain computer three-dimensional model by blue light scanning method, design and make personalized abutment and all ceramic restoration on computer, dye, glaze and bond after trial wearing, the whole restoration is made by chair side, patients can directly participate in the restoration design, and feel more involved. Conclusion: in the implant area of the anterior teeth, compared with the traditional implant repair method, the chair side repair system can get more satisfactory results, which is worthy of clinical application and promotion.
