Eating peanuts or peanut butter on a regular basis can also improve memory and reduce stress in healthy young adults, a study suggests.
The study also found that this effect of peanuts may be related to peanut polyphenol intake and increased levels of short-chain fatty acids and very long-chain saturated fatty acids in feces.The results showed that compared to the control group, subjects in the roasted peanut group had significantly lower anxiety scores. Compared with baseline, subjects in both the roasted peanut and peanut butter groups had significantly improved immediate memory and lower anxiety and depression scores.
Further analysis showed that memory and stress responses in the roasted peanut and peanut butter groups were significantly associated with peanut polyphenol intake as well as fecal short-chain fatty acids, plasma and fecal very long-chain saturated fatty acids.
