Genetically modified tomatoes may be a new source of vitamin D.

Genetically modified tomatoes may be a new source of vitamin D.

Vegetables, including tomatoes, are low in vitamin D. The leaves of the tomato plant, on the other hand, contain an important vitamin precursor in the form of a substance called provitamin D3 (dihydrocholesterol). In general, provitamin D3 is converted to cholesterol by a special enzyme.

Using Crisper gene scissors, researchers at the British Botanical Research Center have tapped into the gene that controls the John Innes enzyme. Conclusion, it is provided Natural plants, Both leaves and fruits are high in provitamin D3. This is usually done without affecting the plant. When the tomato plant was illuminated by ultraviolet light, the substance was converted to vitamin D.

Formed by sunlight

The same chemical process that takes place in the skin when we stay in the sun produces vitamin D. Vitamin D is also available in our diet. Fatty fish, meat and eggs are the main sources. In Sweden, vitamin D is fortified in milk and some other products to prevent deficiencies, especially in winter.

According to researchers, genetically modified tomatoes contain as much vitamin D as two eggs. Genetically modified tomatoes may become the new main source of vitamin D. According to researchers, the leaves can also be used to make natural vitamin D supplements.

UK relaxes GMO rules

So far, the tomatoes have been grown in the laboratory, but field trials are scheduled to begin this summer. However, the road to the vegetable counter is far from straight. In Europe, all genetically modified crops fall within the strict range GMO law This makes it very difficult to get permission for testing and commercial cultivation.
