According to a new study published in American Journal of Clinical Nutrition, fish oil supplements and vitamins B does not protect from depression to patients who had suffered a heart attack or stroke (CVA). Indeed, it seems that the randomized group had taken fish oil showed an increased risk of developing depressive symptoms. The study was based on the monitoring of 2,501 people of 45-80 years who had a heart attack, stroke or severe chest pain by blockage of heart arteries.
The researchers distributed the sample into four groups: one took a mixture of folate and vitamins B6 and B12 daily, swallowed another fish oil capsules, the third consumed fish oil and vitamins B, and the fourth received placebo capsules (control group). During the three to five years, nearly a third of the participants developed any symptoms of depression, and 7%, moderate to severe depression. The group treated with fish oil was 28% more likely to develop depressive symptoms.
The study concludes that there seems no reason for people with heart disease or who have suffered a stroke consume fish oil supplements, B vitamins or omega-3 fatty acids.
