Probiotics Linked to Slower Cognitive Decline in Old Age
A new study suggests that probiotics, already known to help with gut problems, may also slow cognitive decline in old age. Jessica Eastwood, a nutritional psychology researcher at the University of Reading in England, believes that probiotics may have the potential to stall cognitive decline and dementia as people age. The “gut-brain axis” is thought to be the key link between gut health and brain health, and improving gut health could lead to improved brain health.
Probiotics, considered “good bacteria” in the digestive system, can be found in foods such as yogurt, cottage cheese, and kimchi, as well as in over-the-counter supplements. These good bacteria have been shown to alleviate digestive distress, boost immune health, and regulate weight and appetite.
Research has shown that older adults who took probiotics had better cognitive function than those who took a placebo, according to a study presented at the American Society for Nutrition meeting. Ms. Eastwood and her team have published a review suggesting that a daily probiotic might reduce cognitive decline in healthy older adults and those with mild cognitive impairment or Alzheimer’s disease.
While it is clear that there is a link between probiotics and cognitive function, more in-depth trials are needed to determine the exact association. Additionally, researchers are still working to identify which strains of probiotics might be most effective for improving cognitive function.
It is important to note that probiotics may not have the same effect on cognitive functioning in younger people, unless they are stressed. Stress can impact cognitive performance, but taking probiotics may help mitigate this decline.
Although more research is needed, the potential link between probiotics and cognitive decline offers hope for combating age-related memory loss and dementia. For now, those interested in protecting their brain function as they age may want to consider incorporating probiotic-rich foods into their diet, as well as discussing the potential benefits of probiotic supplements with their healthcare provider.
