health benefits of celery 1. May support heart healthAlthough celery has a high water content, it contains numerous vitamins and minerals, including potassium and calcium, which are important for heart health. It also contains folate and vitamin K, both of which are required for the formation of red blood cells and effective blood clotting. Celery is also a good source of protective plant compounds called flavonoids, which have anti-inflammatory and protective effects on the cardiovascular system. Diets high in fibrous foods like celery are associated with a lower risk of heart disease.2. May support digestive functionCelery is a good source of both soluble and insoluble fibre, which is important for digestive function. A 2010 animal study using celery extract also suggested that its phytonutrient content may be beneficial for protecting digestive mucosa, and as a result may guard against gastric ulcers.3. May be anti-inflammatoryRich in plant compounds with anti-inflammatory properties, celery may be a useful inclusion for those with chronic inflammatory conditions like arthritis.4. May improve memoryA 2017 animal study found that celery extract appeared to improve cognitive function associated with ageing and depression. Similarly, a study looking at the neuroprotective benefits of celery extract saw positive results in participants with dementia and Alzheimer’s.5. May improve blood sugar managementWith a low glycaemic index (GI) and a high fibre content, celery is useful for those who need to monitor their blood sugar levels. Studies also suggest it may be effective at reducing blood glucose levels.
