Molecular Healing: More Evidence that Eating Vegetables Can Help Reduce High Blood Pressure
Posted Aug 24 2008 9:52pm
Many of us struggle with getting enough fruits and vegetables in our diets, especially with our busy schedules. We often have to hunt for nutritious foods in our "fast-food" oriented society.
The benefits of consuming fruits and vegetables continues to grow and is supported by numerous studies. Most recently a study conducted at the William Harvey Research Institute at Barts and The London School of Medicine showed that drinking simple beetroot juice can lower blood pressure.
The key appears to be the dietary nitrates contained in beets and green leafy vegetables. This finding is a bit unusual in that many of the healing properties of fruits and vegetables have been attributed to antioxidant properties. As the nitrates pass through the digestive system they become converted into nitrites or nitric oxide in the bloodstream. Nitric oxide works as a vasodilator which helps to open the blood vessels. Nitric oxide is also affected by the popular erectile dysfunction drugs like Viagra. Perhaps beetroot juice can help more than high blood pressure!
The researchers found that the blood pressure lowering effects began about 1 hour after ingestion, peaked about 3-4 hours later and lasted for up to 24 hours.
Fruits and vegetables are powerful molecular information sources for healing. I am always happy to see support for the use of such substances in the literature.
