You're Running Out of Time to Get Ahead of Vascular Aging

Most people think of aging as a linear process. Little by little, your health diminishes, you become more predisposed to diseases, and overall you just can't do the things you used to physically.

A study in Cell, however, reveals that this may not be the case. Researchers studied thousands of proteins across 13 body tissues in individuals age 20-70. What they discovered is that the body remains relatively stable in your 30s and 40s, but age 50 is the tipping point.

On average, age 50 is where the decline starts to happen in a noticeable way. This is particularly evident in cardiovascular health. Blood vessels showed aging signals earliest, before the brain, liver, or other organs.

Scientists identified a protein called GAS6 as a main driver of this vascular aging. GAS6 is a protein dependent on vitamin K that plays a role in cellular aging. It's unclear the role vitamin K plays in this process, however. All we know is that GAS6 plays a roll, it's just not clear what it is yet. Whether it's too much, too little, or overall dysfunction remains to be seen.

With that said, eating foods rich in vitamin K2 like egg yolks is a good way to support the vascular system through multiple pathways. While it may not have a direct effect on GAS6 and aging, it's still sound general health advice.

It's important for individuals to be mindful of their cardiovascular health before age 50. Most people take a reactive approach, rather than a proactive approach, to their health. They wait for a problem before making changes. Maintaining your cardiovascular fitness as you age is a good way to circumvent many of these problems.

Don't wait until something is wrong to make a change. Get regular bloodwork, stay in shape, and be mindful of your biology.
