But a compound in them may be good for Alzheimers:
Salk scientists have found further evidence that a natural compound in strawberries reduces cognitive deficits and inflammation associated with aging in mice. The work, which appeared in the Journals of Gerontology Series A in June 2017, builds on the team's previous research into the antioxidant fisetin, finding it could help treat age-related mental decline and conditions like Alzheimer's or stroke.Speaking of Alzheimers, last night's Four Corners was a sad case study of a few examples of people living with it in Australia. It is a terrible disease, especially with the early onset variety.
The Salk team fed the 3-month-old prematurely aging mice a daily dose of fisetin with their food for 7 months. Another group of the prematurely aging mice was fed the same food without fisetin. During the study period, mice took various activity and memory tests. The team also examined levels of specific proteins in the mice related to brain function, responses to stress and inflammation.
"At 10 months, the differences between these two groups were striking," says Maher. Mice not treated with fisetin had difficulties with all the cognitive tests as well as elevated markers of stress and inflammation. Brain cells called astrocytes and microglia, which are normally anti-inflammatory, were now driving rampant inflammation. Mice treated with fisetin, on the other hand, were not noticeably different in behavior, cognitive ability or inflammatory markers at 10 months than a group of untreated 3-month-old mice with the same condition. Additionally, the team found no evidence of acute toxicity in the fisetin-treated mice, even at high doses of the compound.
