An April 15 2021 Genetic Engineering and Biotechnology News reported that high dietary intake of animal products, processed foods, alcohol and sugar could lead to inflammation in our gut, according to a study by the University of Groningen and University Medical Centre Groningen. This diet showed to support the abundance of inflammatory Firmicutes and Ruminococcus sp in our gut.
A diet rich in plant-based foods was found to promote the opposite affect. For example, nuts, oily fish, fruit, vegetables was linked to a higher abundance of healthy bacteria such as Faecalibacterium sp.
University of Groningen's Laura A. Bolte, PhD, and colleagues, studied 1425 individuals many of whom suffered from some type of gut related disease and compared their diets to a control group of 871 gut healthy individuals.
