Seaweed and fishery products are groups of food with a potential source of probiotics and prebiotics. Research on the gut microbiome has been published widely and reported to be strongly connected to human health by improving host immunity. BFPT held a guest lecture on “Gut Microbiome and Human Health” delivered by Prof. Cindy H. Nakatsu from Purdue University, USA on 10 March 2017. She shared her expertise and research activities on the effect of agricultural-based products on the gut microbiome in children with a controlled diet. Prof Cindy H. Nakatsu is a professor on microbial ecology. Her current research is related to the impact of anthropogenic factors on microbial community structure. She has published many scientific papers and also assigned as a reviewer in reputable journals. This lecture offered a good opportunity to the students to get new insight about microbial community, its role in humans and the environment, and methods for analyzing microbial community structure.
