Scientists in the UK grew special tomatoes with extra vitamin D, which is important for people’s health. Vitamin D deficiency affects about one billion people worldwide. ① Tomatoes naturally contain a substance that gets converted into vitamin D. ② The team altered the genes of the tomato plants, breeding them to have more of this substance than usual. ③ Each tomato came to have about as much vitamin D as two medium-sized eggs. ④ Moreover, tomatoes are commonly eaten raw in salads and served as a cooked vegetable. The scientists think the technique could be used with other foods, too.
