Broccoli Sprouts: In a groundbreaking study recently published in the American Society for Microbiology’s journal MSystems, researchers from the United States delved into the potential of broccoli sprouts and bio-actives to alleviate Crohn’s disease symptoms using a murine model. This study examined the complex relationships between the host and gut flora and how bio-actives relieve Crohn’s disease symptoms.
Crohn’s disease, a form of inflammatory bowel disease often manifesting during childhood and adolescence, presents challenges due to its severe and chronic enterocolitis and dysregulations of the immune system and gut microbiota. The multifactorial origins and diverse symptomatology impact patients’ quality of life, making effective management elusive.

Current treatment options involving immunosuppressants often yield poor responses. Recognizing the potential impact of diet on autoinflammatory metabolites, the study focused on the use of broccoli sprouts containing sulfur-containing glucosinolates, known for their anti-inflammatory properties in the gastrointestinal tract.
The researchers utilized an interleukin ten knockout mouse model, crucial for studying inflammation and immune factors, to examine the interactions between the host, gut microbiome, and broccoli sprouts and bioactives. The murine model, exhibiting interleukin 10 deficiency, plays a significant role in inhibiting the production of inflammatory cytokines.
Raw broccoli contains glucoraphanin, a glucosinolate precursor, and sulforaphane, an anti-inflammatory isothiocyanate. The study aimed to assess how these compounds, present in broccoli sprouts, impact disease severity induced in the mice.
The mice were fed a raw diet containing broccoli sprouts, and disease severity was evaluated based on parameters such as blood in feces, stool consistency, and inflammatory markers in plasma samples. The results revealed that the mice on the raw broccoli sprout diet exhibited higher levels of sulforaphane in their plasma, coupled with improvements in weight stagnation, diarrhea, and blood in the feces.
Additionally, the gut microbiome’s microbial richness increased, and pathobiont bacteria causing inflammation decreased in abundance after the raw broccoli sprout diet. The study highlighted the potential benefits of introducing such dietary interventions early, especially in younger mice with more malleable gut microbiomes.
These findings open avenues for further research on the intricate interplay between host, microbiome, and diet in the context of inflammatory bowel diseases, offering hope for novel and natural approaches to alleviate Crohn’s disease symptoms.
