Tomato paste helps fight sunburn and wrinkles

Medical Science News

Scientists in Britain are suggesting that a tomato product may help fight sunburn and wrinkles.

A study by researchers at Manchester and Newcastle Universities has found that adding five tablespoons of tomato paste to the daily diet of 10 volunteers, their skin's ability to protect against harmful UV rays improved.

Damage from UV rays can lead to premature ageing and even skin cancer and the scientists say it is the antioxidant lycopene found in tomatoes which provided the benefit.

The lycopene in tomatoes is at its highest concentration when the vegetable has been cooked - a link has already been established between lycopene and a reduction in the risk of prostate cancer.

The researchers gave 10 volunteers around 55g of standard tomato paste which contains high levels of cooked tomatoes and 10g of olive oil daily while another 10 participants received just the olive oil.

Tests after three months using UV lamps showed the tomato-eaters were a third better protected against sunburn at the end of the study than at the start, and other tests suggested the tomato-based diet had boosted the production of collagen the protein that keeps skin supple.

The skin samples from the tomato group showed they had 33% more protection against sunburn, the equivalent of a very low factor sun cream and much higher levels of pro-collagen, a molecule which gives the skin its structure and keeps its firm.

Professor Lesley Rhodes, a dermatologist at the University of Manchester says the tomato diet boosted the level of pro-collagen in the skin significantly which suggests a potential for the reversal of the skin ageing process.

The team warn however that tomatoes should be viewed as a "helpful addition" rather than an alternative to suncream and are now conducting research into the benefits of lycopene for the skin.

Other research has shown lycopene may protect against prostate cancer, as well as the lung, bladder, cervical and pancreatic forms of the disease; it may also boost heart health by combating artery-clogging cholesterol.

The study was presented at the British Society for Investigative Dermatology.英国科学家们提出西红柿产品有助于对抗晒斑与皱纹。

曼彻斯特和纽卡斯尔大学的研究人员在一个研究中发现，10个志愿者每天在的饮食里增加5汤匙的番茄酱，其皮肤防有害紫外线的能力得到提高。

紫外线的伤害能够导致皮肤过早老化，甚至导致皮肤癌，科学家表示在番茄里发现的抗氧化剂——番茄红素正好能提供防止上述的功效。

当蔬菜被煮熟，番茄中的番茄红素便得到它的最大浓缩——这条链已被建立在番茄红素能减少得前列腺癌的风险中。

研究人员每日给予10名志愿者55g左右的标准番茄酱和10g橄榄油，其中番茄酱包含高度煮熟的番茄，而给予另外参与者仅仅是橄榄油。

试验历经的三个月后，在紫外灯照射中显示番茄食用者的防晒斑能力相比研究开始时得到三倍的提高，同时其他试验也提出以番茄为基食已推进了胶原产品出现，一种保持皮肤柔软的蛋白质。

从食用番茄的小组中抽取的皮肤样本显示：他们中33%的防晒斑能力更强了，相当于使用一种非常低效的太阳油和获得非常高量的原骨胶原，一种令皮肤自构和保持坚固的分子。

曼彻斯特大学的皮肤科医生Lesley Rhodes教授意味深长地表示食用番茄可以使皮肤中骨原胶原水平得到增进，这就暗示可以逆转皮肤老化的进程。

这个研究小组发出警告，不管怎样，番茄应该被视为一种增效物，并非胜于太阳油的可选择品，而且正引导人民探究番茄红素对皮肤的功效。

另外，有调查已经表示番茄红素也许能防前列腺癌，也可以防止肺、膀胱、子官颈和胰腺形式的疾病；其同样可能通过抗击胆固醇动脉堵塞增进心脏健康。
