Immunity Boost

|

Feed your immune system well, and watch your vitality soar.

Why are we healthy when we’re healthy? This is one of those questions that only occurs to us when, suddenly, we’re not. We have our immune systems to thank, of course; they are just so reliably consistent that we tend to pay attention to them only when something goes awry. In reality, our bodies are under continuous assault, constantly fighting off rogue forces in an effort to keep us healthy.

On a good day, it’s just run-of-the-mill germs, the sun’s damaging rays and various other outside factors that take aim at us. If our immune systems are functioning well, those little insults are easily overcome, and we feel great. On a bad day, the worst assaults, like dreadful infectious diseases — or cancer — make us suddenly aware of how vulnerable our immune systems really are, and leave us wondering what we can do to maximize their effectiveness.

But wouldn’t it work better if we thought of our immune systems before we got sick? Rebecca Katz, MS, thinks so. Katz is one of the country’s leading authorities on how to eat for health during cancer and the author of the new cookbook and nutrition resource The Cancer-Fighting Kitchen: Nourishing, Big-Flavor Recipes for Cancer Treatment and Recovery (Celestial Arts, 2009).

“It’s not just people with cancer who need healthy immune systems,” explains Katz. “That’s one of the big changes from the time my first book came out,” she says, recalling her 2004 book, One Bite at a Time (Celestial Arts). “It’s only been a few years, but in that time there has been so much more scientific understanding of the role of real food in creating a healthy environment inside the body.”

Her mission as chef at the Commonweal Cancer Help Program in Marin County, Calif., is to manage that ecosystem in two ways: by creating an environment in which the immune system can function well; and by creating an environment that’s inhospitable to cancer.

But can you really improve your immune system simply by adjusting your diet? “A thousand times, yes!” Katz exclaims. “So many studies have been published that show we can influence the quality of our immune system,” she says. “You want to fuel your body with foods that are high in antioxidants and micronutrients. But your body needs food,” she emphasizes, “not just supplements!

“The body often doesn’t know what to do with supplements,” she adds. “Somebody once called me and said, ‘I heard about this antioxidant — resveratrol. Where can I get that so I can cure my friend’s cancer?’ I had to tell her it doesn’t work that way. You can’t just take a lot of supplements or vitamins and cure cancer. In fact, if you megadose on a lot of pills, it can sometimes make your cancer worse.

“Keep in mind that all the good stuff in real food is bioavailable — that is, your body knows how to get it, and it’s presented alongside other stuff that makes it work,” she explains. “And food isn’t just antioxidants and vitamins: It’s fiber and good fats and we don’t even know what else. But it’s coming from the earth and the sun, and it’s what we need to survive.

“I always explain to people that great taste and great nutrition can sit together at the table,” says Katz. “But if you want to nourish yourself, your food has to taste really wonderful. So many people believe that healthy food is hippie gruel that doesn’t taste good. But that’s not true! Real, whole foods, in all their edible parts, are delicious, and those are the things that will connect you back to life and health.”

And if you’re already — knock on wood — healthy? Well, those real foods (like the delicious Chickpea Burgers pictured above) might be just what you need to keep your immune system chugging along on all cylinders, giving you the healthy glow that is your great gift and privilege to enjoy.

Emerald Greens With Orange

Serves four
  • 2 tbs. extra virgin olive oil
  • 1 tsp. minced garlic
  • Pinch of red pepper flakes
  • 2 tbs. dried cranberries
  • 1/4 cup freshly squeezed orange juice
  • 6 cups stemmed and chopped Swiss chard, in bite-size pieces
  • 1/4 tsp. sea salt
  • 1/2 tsp. orange zest
  • 1/4 tsp. maple syrup

Heat the olive oil in a large sauté pan over medium heat, then add the garlic, red pepper flakes, cranberries and orange juice, and sauté for 30 seconds, just until aromatic. Add the chard, salt and zest, and sauté until the color of the chard begins to darken and intensify. Use a slotted spoon to transfer the greens to a bowl, then bring the liquid in the pan to a boil. When the liquid shrinks in from the sides of the pan and thickens a bit, stir the greens back in, then stir in the maple syrup. Taste, and add another pinch of salt if necessary. Serve immediately. Variation: To make this a real jewel of a dish, omit the cranberries and sprinkle 2 tablespoons of gorgeous ruby red pomegranate seeds over the greens just before serving.
