29 May 2018 --- A study published in the Journal of American College of Cardiology has found that commonly consumed vitamin and mineral supplements may offer no consistent health benefits. Researchers from the St Michael's Hospital and the University of Toronto in Canada conducted a systematic review of existing data and single randomized control trials and concluded that no supplements demonstrated advantages in the prevention of cardiovascular disease, heart attack, stroke or premature death. Overall, they recommend a healthy diet for the adequate intake of nutrients.
