In our practice we are great proponents of juicing and its many health benefits. One veggie that is in many of the recipes that we recommend for specific eye conditions such as diabetic retinopathy and eye floaters is the humble seeming beet. We have known for a long time the beet helps to improve circulation and also purifies and builds up the blood.
New research finds that the nitrates found in beet juice both widen blood vessels and increase blood flow to the brain.
In a study of 14 people over age 70 published in Nitric Oxide: Biology and Chemistry, the participants who ate a high-nitrate diet featuring beet juice showed increased blood flow to the white matter of the frontal lobes of their brains. Dementia and other related conditions are most commonly associated with the degradation of that part of the brain.
