New study: Several fish meals per week and monounsaturated fatty acids such as those found in olive oil or nuts had an effect in older women.
EA Mediterranean diet high in fresh fish and monounsaturated fats, such as those found in olive oil, may potentially reduce the risk of depression. At least that is the result of a study carried out in… British Journal of Nutrition has been published. However, the effect was only seen in women.
If they consumed three or more portions of fresh fish weekly, their risk of depression was reduced by 62 percent. There was no effect on canned tuna. But monounsaturated fatty acids, which are found in olive oil, avocados and many nuts, also had a positive effect on the risk of depression.
A possible explanation is that the omega-3 fatty acids in fish and also the monounsaturated fatty acids have anti-inflammatory properties. Their influence on neurotransmitters in the brain might reduce the risk of depression.
differences
325 men and 473 women between the ages of 65 and 97 took part in the Italian “NutBrain Study”. 28 percent of women and 8 percent of men reported symptoms of depression. This difference might also explain why an effect was only seen in women. Since this was an observational study using a questionnaire, it cannot be ruled out that factors other than diet might also have played a role.
