Berry Bonanza

Spring is wonderful for many reasons, not the least of which is the return of fresh ripe berries. Every week, I hustle to my farmers markets to see what is waiting for me. Right now, it’s strawberries: picked at their peak, they are tender, sweet, juicy and red throughout – but they have a very short season, so get them while you can!

There are very few foods that match the beautiful color and intense flavor of berries. And, fortunately, these fruits are nutrition superstars.

For many years, most berries were regarded as nutritionally inferior because of their lack of traditional essential nutrients such as vitamins A and C. But that was before scientists recently discovered the presence of large amounts of beneficial phytochemicals (“phyto” is Greek for plant).

Apparently, each berry contains at least 100 nutrients and phytochemicals, the plant compounds with potent powers of healing. Some of the most important phytochemicals in berries are antioxidants, powerful substances believed to reduce inflammation, improve immune function and help prevent heart disease and cancers.

Antioxidants are compounds that absorb oxygen free radicals — molecules that cause oxidation in the body’s cells. Scientists believe that these molecules cause most of the diseases of aging, such as immune system decline, arthritis, heart disease, cancer and neurological impairments affecting cognition and balance. Think of oxidation as being similar to rusting. Or imagine an apple slice turning brown. By simply adding lemon juice, an antioxidant, the apple’s flesh stays fresh and prevents the browning or oxidation.

A similar thing happens in your body. Oxidation is constantly occurring in your cells because of environmental pollutants, smoking, exposure to the sun, heat generated through basic metabolic functioning, unhealthy diets and other factors. It takes a large supply of antioxidants to counter this. Berries have been found to have one of the highest antioxidant scores of all fruits and vegetables.

But there are other good reasons to eat berries. The berry family contains 300 to 400 beneficial, disease-fighting chemicals. The phytochemicals in berries, depending on the type, also stimulate the immune system, reduce inflammation, enhance cancer-fighting enzymes, positively influence hormone metabolism, have antibacterial and antiviral effects and may even reverse some aspects of brain aging.

The most potent berries are the more deeply colored varieties, especially blackberries, blueberries and cranberries, followed by raspberries, strawberries and cherries (not technically a berry, but similar nutritionally) but all more potent than most other fruits. Their color is provided by one of the most powerful phytochemicals, called anthocyanins, which berries synthesize to protect themselves from the elements.

“Anthocyanins play a role in . . . protecting against cancers of the gastrointestinal tract,” says Ronald Prior, nutritionist at the Arkansas Children’s Nutrition Center in Little Rock. “Blackberries have been shown in animals to protect against colon and esophageal cancer.” A preliminary human study found blueberries inhibited blood clotting, a risk factor in cardiovascular disease.

The anthocyanins in berries also may be responsible for improving some aspects of aging, such as memory, motor coordination, balance, vision and even symptoms of Alzheimer’s disease, according to many years of animal studies.

“Blueberries have interesting, surprising qualities,” said Prior. “We’re hoping foods such as blueberries can help prevent Alzheimer’s disease in humans as they do in rats.”

The scientists found similar effects in cranberries, which have additional phytochemicals called tannins. They may be responsible for helping to prevent urinary tract infections, stomach ulcers, gum disease and even ear infections in children. Cranberries are also effective against antibiotic-resistant bacteria — and 20 percent of urinary tract infections are resistant to antibiotics. The tannins work by blocking the disease-causing bacteria and preventing it from adhering to human cell walls.

Resveratrol

New research has found that raspberries, blueberries, cranberries and huckleberries contain a phytochemical called resveratrol, also present in wine, which is thought to help prevent cancer, cardiovascular disease, and is implicated as an important compound in the health benefits of the “French Paradox.”

Strawberries contain large amounts of phytochemicals called ellagitannins, which are also in raspberries and blackberries. Studies at the UCLA Center for Human Nutrition found those berries are capable of inhibiting a number of key steps in the development of cardiovascular disease and may have immense potential for the prevention and treatment of heart disease and stroke. Strawberries are also high in antioxidant Vitamin C and folic acid, important in preventing birth defects.

Most of what scientists know about berries has been determined in animal studies and in labs using cell cultures. But the few human clinical studies are showing promising results. Human studies on berries are limited because they’re very expensive, and as one scientist explained, “You can’t patent a berry!” This means that big pharmaceutical companies are unwilling to foot the research bill. Groups such as blueberry or strawberry growers fund some, but it’s up to Uncle Sam to find out if we can save millions on medications and hospitalizations by simply eating more berries.

Berries are an ideal food. Besides being absolutely delicious and colorful on a plate, they’re loaded with nutrients, vitamins, minerals, fiber, and they’re low in calories. They have maximum flavor and nutrient content when picked at ripeness. Freezing them when ripe or buying ripe frozen berries is a great alternative. But, simply ripening a berry on your kitchen counter will increase its phytochemical content, too.

Berries can be eaten morning, noon or night – whatever your preference. I eat berries every morning on my oatmeal. In the summer, I’ll use any fresh local berry but in the winter, I stick with frozen blueberries.

“Berries are extremely versatile; they fit perfectly with any meal or snack,” says Janie Hibler, author of “The Berry Bible” (William Morrow, 2004). In “The Berry Bible,” Hibler provides a berry encyclopedia and berry recipes ranging from smoothies, drinks, and breads to soups, salads, salsas, main courses, and desserts.

So, what are some ways we can eat berries every day?

“A no-brainer,” she says, “is a berry smoothie for breakfast.” For lunch, she says, throw a handful into your salad. For snacks, carry dried berries and nuts. At dinner, berries go beautifully with meats, grains and main courses.

You will eat more berries if you simply keep them on hand and ready to grab. Get them now when they’re fresh and freeze them yourself. Frozen blueberries are fun snacks for kids to pop in their mouths, like hard candy. You can also make berry popcicles, syrups for pancakes and spritzers.

Berry Coulis

Hibler recommends always having berry purees, or “coulis” on hand. “A sauce rivaled by none,” she says. But they also are great added to drinks, smoothies, yogurts, cereal, you name it. To make a coulis, rinse and drain the berries, process in a food processor. Add a little sugar or even liqueur, if desired. It will keep in your refrigerator for three to four days or be frozen for a month.

Super Fruits & Vegetables

Every Sunday morning I rush to my Farmer’s Market (www.FreshFarmMarkets.org) to taste the latest local delicacy. It’s the highlight of my week. Lately I’ve been buying several quarts of strawberries weekly, but starting soon, I’ll have cherries, blueberries, raspberries, blackberries, plums, peaches, and more to choose from!

This is the perfect time of year to enjoy the most ripe, fresh, flavorful fruits and vegetables – as you can get just about everything you need locally. Whenever my clients make a large purchase at their Farmer’s Market, they see a nice reduction on their scale. This is because fruits and vegetables are the lowest calorie foods you can eat. But they also give you plenty of volume from their naturally high water content – and this helps you feel nice and full.

Fruits and vegetables not only help you lose weight, but improve your health dramatically.

More than 200 studies of various research designs have revealed a strong association between diets high in vegetables and fruits ( five cups daily) and a lower risk for cancer. This is why the National Cancer Institute recommends a minimum of five servings of fruits and vegetables daily.

The American Heart Association is also getting into the act. Its latest guidelines place more emphasis on eating fruits, vegetables, and whole grains, rather than on restricting fat because of fruits’ and vegetables’ influence on the prevention of heart disease and high blood pressure.

Many other health organizations, as well as the United States Department of Agriculture, are getting on the bandwagon and recommending a plant-based diet as protective against chronic diseases.

The research is clear and compelling. We‘ve known the positive statistics for decades. (Of course, our grandmothers knew them before the scientists did… and Thomas Jefferson, before that!) But scientists are just beginning to understand why fruits and vegetables prevent disease so effectively.

Apparently, each fruit and vegetable is a little factory of nutrients and chemicals — called phytochemicals — with potent powers of healing. An apple alone contains more than 150 beneficial, disease-fighting chemicals. And these are substances you can’t get from a pill. They act synergistically in the foods so the whole is greater than the sum of its parts. While an apple has only 6 mg of Vitamin C, it has 1,500 mg of Vitamin C anti-oxidant activity because of the interaction of the Vitamin C and the other nutrients in the apple.

Research has found that when some substances are added together, they boost each other and produce more than a double effect. This may explain why studies on supplements have failed to show the same health-enhancing and cancer-preventive effects as a diet high in vegetables and fruits — the whole foods..

The phytochemicals in fruits and vegetables, when eaten whole, have antioxidant effects, stimulate the immune system, enhance cancer-fighting enzymes, influence hormone metabolism positively, and even have antibacterial and antiviral effect. Phytochemicals are the compounds found in plants. (“Phyton” means “plant” in Greek.) By definition, all plants contain them. The term technically includes vitamins, minerals and fiber. But in the common usage, it has come to refer to all the other compounds in plants that our bodies have evolved uses for. Many of these compounds are potent antioxidants. Others are anti-inflammatories, and still others stimulate the body’s detoxification enzymes.  You get them in sufficient quantities by eating the 5 cups of fruits and vegetables that the USDA recommends. All fruits and vegetables contain them–but the greatest concentration of beneficial phytochemicals is generally found in the most intensely colorful fruits and vegetables. (Notable exceptions would be onions, garlic and cauliflower.)

More than 900 different phytochemicals have been found in plant foods and more will be discovered. These protective plant compounds are an emerging area of nutrition and health, with new research reported every day.

Powerful Fruits and Vegetables That Hold Promise for Human Health

While eating a variety of fruits and vegetables is recommended for maximum health, there are some which we call the “superstars,” which you should try to eat daily.

1. Broccoli Family

People who regularly consume brussels sprouts, cabbage and broccoli have reduced incidence of certain cancers, especially cancer of the colon. They actually provide potent anti cancer enzymes in the body.

2. Tomatoes

Men who consumed 10 or more servings of tomato products a week had a 35% decrease in risk of prostate cancer relative to those who consumed 1.5 servings or fewer per week. This is largely attributed to “lycopene” in the tomatoes, which is also in other red fruits such as watermelon, pink grapefruit and guava. Men with lycopene levels in the top 20% had a 46% decrease in risk of heart attack compared to those in the bottom 20%. Lycopene is a potent scavenger of gene-damaging free radicals.

3. Dark Green Leafy Veggies (kale, spinach, collard greens and turnip greens)

People who consumed spinach or collard greens 2 to 4 times per week had 46% decrease in risk of age-related macular degeneration (the leading cause of preventable blindness) compared to those who consume these vegetables less than once per month. This is attributed to the phytochemical “lutein” in the carotenoid family. Absorption of carotenoids in your body is increased by cooking and by the presence of fat (so cook in a little healthy olive or canola oil!)

4. Garlic

The Iowa Women’s Study found the risk of getting colon cancer was decreased by 32% in realistic periodic consumption of garlic. This is largely attributed the the “alliinase” found in garlic. Allinase is preserved in foods if garlic is crushed and allowed to stand for 10 minutes before it is cooked. This result should also be found in other “Allium” family foods: onions, leeks, chives, scallions.

5. Berries and Red/Purple Grapes

Red/Purple fruits and vegetables such as red and blue grapes, blueberries, blackberries, cherries, strawberries, beets, eggplant (skin), red cabbage, red peppers, plums and red apples are loaded with powerful antioxidant called “anthocyanins.” They delay cellular aging and prevent formation of blood clots. Full of potent antioxidants and anti-inflammatory compounds. In animal studies.

“In tests at Tufts University, blue foods quenched more free radicals than any other foods. Blueberries and blackberries were clear winners among fresh fruits.”
