Older people who take a daily prebiotic fiber supplement may perform better than others on cognitive tests of memory and processing speed. Placebo-controlled trials have assumed researcher biases.

The King’s College London is home to the UK’s largest adult twin registry, with twin studies proving very useful for distinguishing the effects of genetics and environment on human health.

After three months, the twins who took – without knowing it – one of the two prebiotics generally performed better than their co-twins on cognitive tests of memory and reactivity. Daily fiber supplementation has also been linked to small changes in gut microbiota, BacteriaBacteria Beneficial (eg Bifidobacteriam). ” Unlock the Secrets of the Intestinal Axis-the brainthe brain May provide new approaches to living longer in good health Mary Nee Lochlen, Geriatric Medicine Researcher King’s College From London.
The researchers note that although these prebiotics are important factors in maintaining the musculoskeletal system, muscle strength did not improve in the participants. Additionally, the majority of twins were female, which may have included some selection bias groupgroup.
