"text = 'Folic acid will be added to non-wholemeal flour from the end of 2026 to prevent birth defects, the Government has announced. Ministers said the UK-wide legislation would prevent around 200 cases of neural tube defects every year and improve health of pregnant women. It has been estimated that the move to include folic acid in flour will reduce neural tube defects by 20% in the saving the NHS £20 million over 10 years and boosting the economy by more than £90 million. NHS recommendations that women who are trying for a baby take folic acid supplements for around three months before getting pregnant and for at least 12 weeks after will remain in place. But with around half of all pregnancies in the UK are unplanned, it is hoped the new regulations will help provide women with a higher baseline intake of folic acid. '"
