Researchers in Germany have found that individuals who with a high daily intake of vegetables and fruits have higher cognitive performance.
Subjects with a high daily intake (about 400 g) of vegetables and fruits had higher antioxidant levels, lower indicators of free radical-induced damage against lipids as well as better cognitive performance compared to healthy subjects of any age consuming low amounts (< 100 g/day).
These findings are independent of age, gender, body mass index, level of education, lipid profile and albumin levels, all factors able to influence cognitive and antioxidant status. The relevance of the findings is also strengthened by the large sample that included 193 healthy subjects.
Further studies are planned that will include larger subject cohorts, patients with Alzheimer's disease at different stages and patients with mild cognitive impairment without dementia.
