Health benefits of strawberries

Not only can strawberries reduce memory decline, but they can also reduce the risk of developing Alzheimer’s’ disease, which currently affects 1 in 14 people over the age of 65 (Alzheimer’s Society, 2014). A study by Currais et al (2014) assessed the effect of fisetin-infused water on the development of Alzheimer’s in mice that both had and did not have an Alzheimer’s gene.
Fisetin is a flavanol which is prolific in strawberries, and has been shown to protect neurons from degeneration due to ageing. The researchers found that within nine months, mice without the water began to lose their cognitive abilities, including getting lost in a water maze they were previously proficient at.
On the other hand, those who had consumed fisetin-infused water kept a similar cognitive profile to those of the mice without the gene for Alzheimers.
Although this study is clearly using animal models instead of humans, the results may very well be transferable. Very often in science, animal models are used first to assess the possibility that the same effect will occur in humans. This prevents unnecessary harm to humans.
Following successful animal trials, human trials can then take place. Mice models for Alzheimer’s disease prove to be particularly effective for representing disease progression in humans, and often provide transferable results.
