Nowadays High blood pressure or hypertension is one of the common health problem. It can lead to serious health problems, including heart failure, stroke, kidney disease, vision loss, etc. There may be no single cause for high BP in most cases, perhaps, no one really knows exactly what causes this condition. Eating a diet high in fats and salt can lead to hypertension. But certain foods have been found to have blood pressure-lowering effects and one such being onions.
While all vegetables are good for health, there are certain foods that have unique medicinal properties. Onions are low in calories but packed full of nutrients, vitamins, minerals, and fibre. The humble vegetable is rich in antioxidants, particularly vitamin C that offer many benefits such as protection against immune system deficiencies, cardiovascular disease, etc. The antioxidants and compounds in onions can help fight inflammation, lower triglycerides and reduce cholesterol levels - all of which may be beneficial for your cardiovascular health.
According to a study a dose of 162mg per day of quercetin-rich onion extract significantly reduced systolic blood pressure by 3-6mmHg compared to a placebo. Additionally, onions are a healthy choice for people with type 2 diabetes as the vegetable can help control high blood sugar. Eating foods, such as garlic and onions, has also been linked to a reduced risk of certain cancers - such as stomach and colorectal cancer.
