3 Foods To Power Up Your Performance & Immunity

Want to boost your workout performance and increase your body’s natural defenses? But of course! Turns out three foods can do the trick.

Before you learn the first one, here’s a bit about how it helps.

Nitrate Power

Nitrates are nutrients found within certain foods. They bring oxygen to muscles to fuel work and improve performance.

From: How Not to Die

Nitrates, concentrated in green, leafy vegetables and beets, not only help deliver oxygenated blood to your muscles by helping dilate your arteries but also enable your body to extract more energy from that oxygen – something never before thought possible.

Did you notice green leafy vegetables and beets?

These foods have nitrate power, especially beets.

Run with the Beet

Want to run better?  Eat some beets. It worked for 5K runners.

From: How Not to Die

In another study, men and women eating one and a half cups of baked beets seventy-five minutes before running a 5K race improved their running performance while maintaining the same heart rate and even reported less exertion.

Faster times with less effort. Beet me up!

Next, don’t be shy to liquefy…

You Juicin’?

Beet juice works too. Just ask cyclists. They were happy to ride with this finding.

After sipping beat juice, cyclists were able to perform at the same level of intensity while consuming 19 percent less oxygen than the placebo group. The beet-juice drinking group exhibited greater endurance while using less oxygen. In short, the beet juice made the biker’s bodies’ energy production significantly more efficient. No drug, steroid, supplement or intervention had ever before been shown to do what beet juice could do.” 

What’s the ideal amount of beets for better performance?

From: How Not to Die

To maximize athletic performance, the ideal dose and timing appears to be a half cup of beet juice (or three three-inch beets) two to three hours before a competition.”

We know beets rock. Next let’s look at foods to boost your immune system.

Green Light

It’s a go for leafy greens. And who knew they were on the cutting edge of immune science?

According to research from the Babraham Institute, eating green vegetables give us more than just vitamins and minerals.

“Green vegetables of all types are also a key source of specialized chemical signals that our immune systems use to self-communicate.”

This is a huge deal. Why?

Good communication boosts immunity.


Other researchers found that proteins in leafy green cruciferous vegetables interact with surface cell receptors that switch on T-bet to initiate the innate immune response in the digestive tract. That’s where 80% of our immune system resides.

But wait! There’s more…

Researchers also found that a special type of immune cell known as an innate lymphoid cell (ILC) is found throughout the digestive tract. It can protect the body from invading pathogens (big word for bad stuff that causes disease).

“Further, the team determined that ILC’s produce a hormone (interleukin-22) that protects the body from invading bacteria and help maintain a healthy environment in the intestine by balancing bacteria levels, and may also help to resolve cancerous digestive lesions.”

Go Green! Not a fan of the green team? Maybe you’ll like blue…

Berry Nice for Immunity

When it comes to berries, 3 choices come to mind: rasp-, straw-, and blue-.

Which is best?

When it comes to immune boosting power, think blue.

From: How Not to Die

In one study, researchers asked athletes to eat about a cup and a half of blueberries every day for six weeks to see if the berries could reduce the oxidative stress caused by long-distance running. The blueberries succeeded, unsurprisingly, but a more important finding was their effect on natural killer cells. Normally, these cells decrease in number after a bout of prolonged endurance exercise, dropping by half to about one billion. But the athletes consuming blueberries actually doubled their killer cell counts, to more than four billion.

More natural killer cells (term used by immune experts) means better immunity. Blue berries are good, even for low carb dieters. Of the recommended fruits, low carb researchers found blueberries (5-10 carb grams per day) to be a top choice.
