Some previous researches have found viatmin C, E and beta carotene linked to reduced risk of cardiovascular disease, but a new study published in the journal Archives of Internal Medicine casts doubt on these findings.
The latest study involved 8000 women who have a history of cardiovascular disease, randomly assigned to 2 groups : one taking vitamin alone or in combination and one a placebo over 9 years. The results showed that the antioxidants, either alone or in combination had no effect on reducing the risk of heart disease or death in high-risk women.
Some experts suggested that the form of vitamin in over-the-counter dietry supplements may be different from the vitamins found in fruits and vegetables and recommended that lifestyle change with healthy diet and regular exercises is the key to prevent heart disease.
