British researchers have found that adding cooked tomatoes to your diet may help increase your skin's ability to resist harmful ultraviolet rays and ageing in sunlight.
BBC recently reported that researchers from the University of Manchester and Newcastle University studied 20 volunteers. Ten volunteers consumed about 55 grams of standard tomato sauce (mainly cooked tomatoes) and 10 grams of olive oil each day, while the other 10 consumed only olive oil. Three months later, volunteers who consumed both olive oil and tomato sauce improved their skin protection capabilities by 33% compared to volunteers who consumed only olive oil.
Although a variety of fruits and vegetables contain an antioxidant called lycopene, the top priority of cooked tomatoes is the sunscreen effect.
The study also found that the content of collagen in the skin of volunteers who consumed tomato sauce significantly increased. The researchers pointed out that collagen can tighten the skin, and its content increases may delay or even reverse the skin aging process to a certain extent.
In this study, volunteers consumed 5 tablespoons of tomato sauce each day. The researchers said that it is not difficult for people to eat the equivalent tomato in daily life. However, they also pointed out that tomato skin care capabilities are relatively low and can only be used as a "useful supplement", rather than replacing sunscreen and other functions.
The study, the researchers said, was small and not long-lasting and they were planning a new study on the benefits of lycopene on the skin.
