The Link Between Plant-Based Alternatives and Depression in Vegetarians

Researchers from vHive and the University of Surrey have found that vegetarians who consumed Plant-Based Meat Alternatives (PBMAs) had a 42% increased risk of depression compared to those who did not. 

The study, led by PhD student Hana Navratilova, analysed UK Biobank data from individuals who follow vegetarian diets. They found that those consuming PBMAs had higher blood pressure and C-reactive protein levels (an inflammatory marker). However, PBMA consumption was also linked to a 40% reduction in the risk of developing Irritable Bowel Syndrome, suggesting the key may be to incorporate PBMAs only as a part of an overall balanced diet.

Ultra-processed PBMAs can be a useful way for people to transition to a vegetarian diet effectively, and that helps with sustainable agricultural practices. Further research, including longitudinal studies and trials with more diverse populations, is necessary to confirm these findings, and the relationship between vegetarian foods and mood.
