Make Every Meal Healthier

Use these simple strategies to boost the health benefits of your produce

While we've been dutifully eating our fruits and vegetables all these years, a strange thing has been happening to our produce. It's losing its nutrients. That's right: Today's conventionally grown produce isn't as healthful as it was 30 years ago—and it's only getting worse.

In 2004, Donald Davis, PhD, a former researcher with the Biochemical Institute at the University of Texas, Austin, led a team that analyzed 43 fruits and vegetables from 1950 to 1999 and reported reductions in vitamins,  minerals, and protein. Using USDA data, he found that broccoli, for example, had 130 mg of calcium in 1950. Today, that number is only 48 mg.

What's going on? Davis believes it's due to the farming industry's desire to grow bigger vegetables faster.  The very things that speed growth—selective breeding and synthetic fertilizers—decrease produce's ability to synthesize nutrients or absorb them from the soil.

A different story is playing out with organic produce. "By avoiding synthetic fertilizers, organic farmers put more stress on plants, and when plants experience stress, they protect themselves by producing phytochemicals," explains Alyson Mitchell, PhD, a professor of  nutritionscience at the University of California, Davis. Her 10-year study in the Journal of Agricultural and Food Chemistry showed that organic tomatoes can have as much as 30% more phytochemicals than conventional ones.

But even if organic is not in your budget, you can buck the trend. Here,  9 expert tips to put the nutrient punch back in your produce.

1. Sleuth Out Strong Colors

"Look for bold or brightly hued produce," says SherryTanumihardjo, PhD, an associate professor of nutritional sciences at the University of Wisconsin-Madison. A richly colored skin (think red leaf versus iceberg lettuce) indicates a higher count of healthy phytochemicals. Tanumihardjo recently published a study showing that darker orange carrots contain more beta-carotene.

2. Pair Your  Produce

"When eaten together, some produce contains compounds that can affect how we absorb their nutrients," explains Steve Schwartz, PhD, a professor of food science at Ohio State University. His 2004 study of tomato-based salsa and avocado found this food pairing significantly upped the body's absorption of the tomato's cancer-fighting lycopene.

3. Buy  Smaller  Items

Bigger isn't better, so skip the huge tomatoes and giantpeppers. "Plants have a finite amount of nutrients they can pass on to their fruit, so if the produce is smaller, then its level of nutrients will be more concentrated," Davis says.

4. Cook Smarter

Certain vegetables release more nutrients when cooked. Broccoli and carrots, for example, are more nutritious when steamed than when raw or boiled—the gentle heat softens cell walls, making nutrients more accessible. Tomatoes release more lycopene when lightly sauteed or roasted, says Johnny Bowden, PhD, nutritionist and author of The Healthiest Meals on Earth.

5. Eat Within a Week

"The nutrients in most fruits and vegetables start to diminish as soon as they're picked, so for optimal nutrition, eat all produce within 1 week of buying," says Preston Andrews, PhD, a plant researcher and associate professor of horticulture at Washington State University. "If you can, plan your meals in advance and buy only fresh ingredients you can use that week."

6. Skip Time-Savers

Precut produce and bagged salads are time-savers. But peeling and chopping carrots, for example, can sap nutrients. Plus, tossing peels deprives you of good-for-you compounds. If possible, prep produce just before eating, says Bowden: "When sliced and peeled or shredded, then shipped to stores, their nutrients are significantly reduced."

7. Mix Them Up

If you're used to munching on red tomatoes, try orange or yellow, or serve purple cauliflower along with your usual white. "Many of us buy the same kinds of fruits and vegetables each week," Andrews says. "But there are hundreds of varieties besides your usual mainstays—and their nutrient levels can differ dramatically. In general, the more varied your diet is, the more vitamins and minerals you'll get."

8. Opt for Old-Timers

Seek out heirloom varieties like Brandywine tomatoes, Early Jersey Wakefield cabbage, Golden Bantam corn, or Jenny Lind melon. Plants that were bred prior to World War II are naturally hardier because they were established—and thrived—before the development of modern fertilizers and pesticides.

9. Find a Farmers' Market

Unlike prematurely picked supermarket produce, which typically travels hundreds of miles before landing onstore shelves, a farmers' market or pick-your-own venue offers local, freshly harvested, in-season fare that's had a chance to ripen naturally—a process that amplifies its amount of phytonutrients, says Andrews: "As a crop gets closer to full ripeness, it converts its phytonutrients to the most readily absorbable forms, so you'll get a higher concentration of healthful compounds."
