Bitter Foods May Be Key To Better Immunity, Says This Functional Medicine Expert

What does health taste like? There's certainly no single answer to that question, but we all know that "sweet" can sometimes be dangerous territory for nutrition and health.

Bitter foods and beverages can trigger an entirely different physiological response than sweet ones, especially when it comes to your immunity. Sweet tends to activate cravings and immune vigilance, while bitter activates satiety, detoxification, and immune rejuvenation.

We've all gotten a lot smarter about immunity over the past year, so I won't belabor the point. Suffice it to say, vigilance and boosting can be the last thing we need when so many of our immune systems are stuck on high alert and compromised by chronic inflammation.

So how do you get more bitterness into your diet? You're likely already doing it. Think about coffee, or grapefruit, or the hops in beer. These are all bitter foods with an array of established health benefits.

I've been working closely with Himalayan Tartary buckwheat through my new company, Big Bold Health. This particular species of buckwheat is a powerhouse for nutrition—in particular, it contains key immuno-rejuvenating compounds rutin and quercetin—but it can register as bitter on the palate, so I set out to learn why. I discovered, during the processes of cooking and chewing, rutin breaks down into quercetin, a bitter phytonutrient that's getting a lot of attention these days for its ability to improve immune function.

But there's more to this story. This plant has survived the harsh growing conditions of its Himalayan mountain valleys. It did so by producing a portfolio of unique compounds that became the stress-fighting immune system of the plant itself.

There are lots of ways to get more bitter in your diet without suffering through meals that make your mouth pucker. With dietary supplements, you can enjoy the benefits of bitter compounds without tasting them at all. You can also choose powders and beverages that use healthier sweeteners like monk fruit to downplay the bitter for a better overall taste.

Or, like me, you can do the real work of adjusting your palate. Before you know it, you just might find yourself hungry for more bitter and less sweet.
