Effect of Different Diets on Human Gut Microbiome Health

Abstract

In the past 20 years, research on the human gut microbiome and human health has exploded. Diet and gut microbiota are considered important parts of human health. Therefore, it is important and urgent to dig deeper into the impacts of different diets on the human gut and human health. This paper mainly compared the impacts of plant-based diets and animal-based high-fat low-fiber western diets on gut health and human diseases. Through introducing vegan, vegetarian, and mediterranean diets and related research, plant-based diets are much healthier than high-fat low-fiber western diets when it comes to fighting cancer and maintaining a healthy weight. The paper also focuses on the components and their effects in plant-based food and animal-based foods such as plant protein, animal protein, prebiotics, probiotics, and dietary iron such as heme as well as mentioning the effect of shifting diets. In the future, research can look for more evidence of people who change diets, such as changing from omnivorous to vegetarian, because nowadays more people change diets based due to recognition of the bad effect of western diets. However, those who switch diets may suffer from eating disorders so future research could look into this effect. Overall, this paper gives basic knowledge about the effect of different diets on human gut health and human health.
