Researchers in Norwich, England, have developed genetically edited tomatoes that naturally produce vitamin D, the “sunshine vitamin.” By turning off a specific gene that usually prevents the accumulation of provitamin D, scientists have enabled tomatoes to convert sunlight into this essential nutrient. Four of these tomatoes can provide an adult’s daily requirement of vitamin D. The experiment is part of a clinical trial involving 76 participants, who consume the modified tomatoes in soups while wearing UV-measuring necklaces to ensure the vitamin comes from the food rather than sunlight.This innovation could help people who lack vitamin D, especially during winter when sunlight is weak. Traditionally, vitamin D is found in foods such as oily fish and eggs, which some people dislike. However, not everyone welcomes genetically edited foods. Critics argue that the removal of labeling rules means consumers won’t know what they are buying, and organic farmers could struggle to avoid contamination. Supporters, including the UK government, believe gene editing can improve food security, reduce disease, and create more nutritious crops. Scientists hope to introduce these tomatoes—and possibly other edited fruits and vegetables—to the market as early as next year.
