Celery and celery extracts are rich in flavonoids, vitamins, minerals, fiber, antioxidants (e.g., polyphenols and phenolic acids), and even essential oils! Further, processing celery to juices or smoothies allows consumption of other antioxidants like chlorophyll and additional fermentation benefits (Zhao et al., 2021; Mezeyová et al., 2018). These beneficial compounds enable celery and celery juices to have various anti-diabetic, anti-obesity, anti-cardiovascular, and anti-inflammatory properties and can reduce blood glucose and serum lipids (Zhao et al., 2021). Studies suggest probiotic fermentation of celery juice can enhance the total polyphenols, flavonoids, vitamin C, etc. that have potent anti-inflammatory properties as well as numerous other health benefits. Fermented celery juice can also produce alterations in the composition of gut microbiota, increasing the ratio of Firmicutes/Bacteroidetes and the relative abundance of beneficial bacteria (Lactobacillus, Ruminococcaceae_UCG-014, Faecalibaculum and Blautia), and decreasing the relative abundance of harmful bacteria (Alloprevotella and Helicobacter), which can contribute to its benefits on reducing obesity and improving metabolic disorders (Zhao et al., 2021). https://pubs.rsc.org/en/content/articlelanding/2021/fo/d1fo00560j/unauth https://www.researchgate.net/profile/Miroslav-Slosar/publication/323870554_Evaluation_of_quantitative_and_qualitative_characteristics_of_selected_celery_Apium_graveolens_var_Dulce_varieties_in_the_context_of_juices_production/links/5b0f9b370f7e9b1ed7037d6b/Evaluation-of-quantitative-and-qualitative-characteristics-of-selected-celery-Apium-graveolens-var-Dulce-varieties-in-the-context-of-juices-production.pdf
