B stands for beets, which benefit Blood pressure and now, believe it or not, Brain health. These important health benefits make a compelling case for trying to develop a taste for beet juice because -- let’s be truthful here -- it’s not something many people are in the habit of drinking regularly.
BEETS ARE EVEN BETTER THAN WE KNEW
The new findings on brain health come from Wake Forest University and were reported in the January 2011 issue of Nitric Oxide: Biology and Chemistry. We already knew that beets have a high concentration of the compound nitrate, which gets converted to nitrite (a vasodilator, which means it expands blood vessels) when it comes into contact with the healthy bacteria that live in the mouth.
In this small study, seven adults (all age 70 or older) each consumed 16 ounces of beet juice with breakfast for two days and then ate a normal, healthful lunch and dinner (that also included some healthful nitrates), after which they had MRI scans to measure blood flow through their brains. At the same time, for the sake of comparison, another group of seven adults of the same age ate a diet that emphasized low-nitrate foods for two days, also followed by MRI scans. The two groups then switched diets for another two days, and had additional MRI scans. Research finding: Drinking beet juice brought increased blood flow to the white matter of the frontal lobes of the brain, the area most strongly associated with degeneration that leads to dementia.
Beet juice has an earthy, slightly sweet flavor but leaves a sour aftertaste -- therefore some people like to add a small amount of apple juice as a sweetener. Many markets now carry beet juice, and some also sell beet juice-extract capsules, for those who really don’t think they can develop a taste for the stuff!
The study tested only beet juice, not whole beets, though lead author Daniel Kim-Shapiro, PhD, director of Wake Forest University’s Translational Science Center, told me that he believes that these would be similarly healthful. Other good sources: Dr. Kim-Shapiro noted that kale, spinach, celery and cabbage are also good sources of nitrate -- he suggests that you might make a "brain cocktail" by juicing some of these foods together in whatever proportion tastes best to you.
IS IT SAFE?
Nitrate-rich beet juice and extract is not advisable for certain groups of people, including those who have or have had nitrate-containing kidney stones and anyone taking nitroglycerin or Viagra. Since beets are high in sugar, people with diabetes should not drink beet juice either and indeed, if you have any chronic medical condition, you would be well-advised to check first with your doctor. But if you like beet juice and your doctor gives you the thumbs up, it’s safe to say you can’t beat beets for brain health!
