"Plant Proteins Promote Better Sleep, Animal Proteins May Disrupt, Study Shows"

A new study suggests that the source of protein in one's diet may impact sleep quality, with plant proteins potentially improving sleep and animal proteins potentially impairing it. While total protein intake showed no significant effect on sleep quality, the study found that higher consumption of plant protein was associated with better sleep quality in women, but not in men. The study also found that processed red meat and poultry were linked to poorer sleep quality, while unprocessed red meat adversely affected sleep in women. However, the study could not establish a causative effect of diet on sleep and further research is needed to verify these findings.
