According to a study from the Pennington Biomedical Research Center, people with a small variety in their diet were more likely to develop type 2 diabetes and obesity. Poor diet diversity is defined as relying on foods that lack a large assortment of nutrients, such as white rice, pastries, pasta, and bread.
It is thought that having a limited diet could potentially weaken the microbiome of the gut. This could then increase the risk of developing metabolic diseases, including type 2 diabetes, inflammatory bowel disease, and obesity. These findings suggest that eating a diverse and balanced diet could reduce your risk of developing one of these conditions.
These findings were published in Molecular Metabolism on March 5, 2016.
