Loosening the Grip of Aging on Your Brain - The Magic of Nitric Oxide
Got your attention? Well, here's something mind-blowing - Nitric oxide (NO) could be the key to keeping your brain ticking like a bloody Swiss watch, even as you age!
NO, a gas produced by your body, was such a game-changer when discovered that the scientists who identified it won a Nobel Prize. It's found in the endothelial cells lining your artery walls, acting as a potent vasodilator that tells blood vessels to relax, expand, and open up.
What's the big deal? You might ask. Well, this little gas helps maintain your blood pressure levels, aids in various cardiovascular functions, improves glucose tolerance, lowers fasting insulin and leptin levels, and even protects cognitive function.
But how, you may be wondering? Let's dive a bit deeper.
Beets - The Brain's Hidden Ally
Have you heard of the connection between beets and brain health? Research suggests that beetroot juice, rich in dietary nitrates, is converted into NO in your body, boosting blood flow to the brain, delivering more oxygen to brain cells, and keeping them functioning optimally.
One study even found that combining beetroot juice and exercise improves brain connectivity, making your brain behave as if it were years younger!
But that's not all. Another study hinted at a different aspect of brain health affected by NO. In this study, a high-salt diet led to dementia in mice. Initially, researchers believed that the salt was responsible for lowering NO levels, but they found that the blood flow wasn't sufficiently restricted to explain the dementia. Instead, they discovered that lower NO levels caused the instability of tau in the brain, leading to dementia.
The Brain's mechanisms behind Age-Related Cognitive Decline
A new study has zeroed in on the mechanism behind age-related cognitive decline. It turns out that declining NO levels are linked to the misregulation of a crucial brain protein called CaMKII, essential for memory and learning.
In mouse models, the researchers found that altering CaMKII had similar cognitive effects as those occurring during normal aging. When both mice and humans age, the amount of NO in the body decreases, leading to decreased S-nitrosylation, a process that modifies specific brain proteins, including CaMKII.
This new research could pave the way for developing drugs and therapeutic interventions that work to normalize the nitrosylation of CaMKII, potentially treating or delaying normal cognitive decline for some time. However, this wouldn't apply to the cognitive decline associated with Alzheimer's disease and dementia.
Boosting NO Levels - Beet Yourself!
Wondering how to get more NO in your life? Start with a balanced diet rich in leafy greens, citrus fruits, and dark chocolate. But if you really want to crank up your NO production, make room in your heart for beets - they're high in dietary nitrates and the ultimate brain boosters!
If you're not a fan of chomping on whole beets, try juicing them and adding the juice to your daily smoothie. Or for a simpler approach, grab a tin of beetroot powder or supplement and take it daily for a brain BOOST!
Remember, moderation is key, so skip the salt, and your NO levels - and heart health - will thank you!
