According to Lauren Manaker, RDN based in Charleston, South Carolina, “A plant-based diet emphasizes foods like fruits, vegetables, and beans, and limits foods like meats, dairy, and eggs. It may completely eliminate foods from animals or just limit intake, depending on the individual’s interpretation.” This does not mean that meat and seafood have to be stopped completely but have to reduce the number of intakes in a week. Lauren further said it is a broad diet category, with other more specific diets under its umbrella.

Researchers from the UK examined the data from 11 clinical trials that examined the effect of a plant-based diet over other diets. According to their findings, a plant-based diet had physical and psychological benefits for those living with type 2 diabetes. For example, for people who ate less or no animal diet, fasting glucose fell sharply, but their symptoms of depression improved significantly. If one has an increased blood glucose level, a plant-based diet can positively impact gut health.
