So, Can Cranberries Improve Memory?

I tend to be hesitant to report on studies of single foods doing amazing things (because many do), but this piece of research still caught my eye.

So, what did this group of researchers from the University of East Anglia find?

Well, they wanted to study the effects of cranberries specifically because they are known to have plenty of flavonoids – healthy compounds which have been shown to have multiple positive effects. This was also studied in an older population of 50- to 80-year olds. Right up my street then. The goal was also to see if it could help with any effects of dementia which is becoming severe in many societies with ageing populations.

They therefore tracked 60 cognitively healthy participants over a 12-week period. Half of the participants consumed powdered cranberries equivalent to 100 grams of fresh cranberries (about a cupful) and the other half consumed a placebo.

What were the results?

Well, the results were pretty impressive. They showed that the cranberry group significantly improved memory function of everyday events (known as episodic memory) but also that the brain exhibited higher levels of oxygenation and enhanced neural functioning. On top of this the cranberry group also exhibited a significant circulating LDL (“bad” cholesterol) decrease.

So, all in that’s top news for cranberries. Whether that is just cranberries is open to interpretation – it is likely the combination of flavonoids that are found in cranberries – but cranberries are particularly rich in them and so it could do you a whole bunch of good. But do remember to keep a healthy diet in general because that will likely have the largest benefits. But if in doubt a cupful of cranberries will do no harm and likely do an awful lot of good!
