Onion supplementation improves body fat, blood pressure and cholesterol
In the first of its kind, a comprehensive review of literature on onion supplementation has found significant cardio-metabolic benefits.
Natural bioactive compounds in onions can help reduce obesity
Onions are rich in bioactive compounds and have been found to help prevent various chronic diseases, including obesity. A systematic review and meta-analysis of five clinical trials (using onions and onion peels) found body weight, body mass index (BMI), waist circumference and triglyceride levels were all significantly reduced in those who consumed onions compared with the placebo group who did not. The authors concluded onion intake had an anti-obesity effect which reduced body weight and body fat, and this effect was particularly pronounced with onion peel.
Neuroprotective effects of onion in Alzheimer’s disease
The protective role of onion against neurodegeneration and Alzheimer’s disease can be attributed to active ingredients such as flavonoids, and quercetin in particular. Quercetin is a phytochemical that possesses antioxidant properties and has a protective effect against ageing – it has anti-oxidative, anti-inflammatory, anti-proliferative, anti-carcinogenic, anti-diabetic and anti-viral properties.
