Microbiome

The varied community of microorganisms that live in different parts of the body, particularly the gut, is referred to as the human microbiome. These microorganisms are mostly bacteria, but they can also be viruses, fungi, and archaea. These microbial communities are vital for immune regulation, nutrition synthesis, digestion, and pathogen defense. Metagenomics research has shown that homeostasis depends on a healthy, diverse microbiome, whereas dysbiosis, or imbalances in the microbiome, is linked to a variety of illnesses, such as obesity, inflammatory bowel disease, allergies, and neuropsychiatric disorders. The field of microbiome research is growing quickly, providing new information on diet-microbe interactions, probiotic treatments, and personalized medicine.

Do gut microbes cause autism? New research says diet plays the bigger role

In a family-based study, researchers found that children with autism spectrum disorder (ASD) shared similar gut microbiomes with their relatives but showed distinctly different eating habits. Their preference for sweets and limited vegetable intake suggests behavior-driven dietary choices may influence, rather than result from, microbiome differences.
