Superfoods for Brainpower

Your brain is the center of your universe. It controls every intentional motion you make, every thought you think, every nightmare that wakes you, and every pleasant dream that visits you in sleep. Without a moment's hesitation, it simultaneously and efficiently regulates a host of unconsidered actions like breathing, heartbeat, muscle contraction, and blinking. Whether you are adding a column of numbers or deciding in a split second how to swerve the car to avoid danger, you don't have to give a your brain a second thought: It is always on call for high-speed service.

No wonder, then, that many people worry about brain-related problems like slowed reaction time and memory loss as they get older. And if someone in your family has had a stroke, it's likely that you will begin to worry about that, too.

Keeping your brain in apple-pie working order and protecting it from stroke are high priorities for the young-at-heart and young-in-the-head who want to stay that way. But how can food help you do that?

More than any other organ in the body, the brain depends on a continuous, oxygen-rich blood supply. That explains why a person becomes confused or loses consciousness during oxygen deprivation—and that's exactly what happens when blood flow to the brain is blocked during a stroke. While nourishment alone can't ensure that your brain will get all the oxygen it needs to keep you thinking young, the right foods can certainly help prevent a mind-altering stroke. According to the American Heart Association, atherosclerosis (clogged arteries) and high blood pressure are two of the leading causes of stroke. To discover why, just touch both of the arteries on either side of your Adam's apple—the carotid arteries—and imagine what happens when those pipelines carrying oxygen-rich blood to the brain are blocked. And even if they are only partially blocked by atherosclerosis, your stroke risk rises dramatically. So any foods you eat to help prevent atherosclerosis will also help to protect the awesome computer at the top of those pipelines.

Strive for Five

Five a Day for Better Health is the national nutrition program started in 1991 by the National Cancer Institute, located in Bethesda, Maryland, and the Produce for Better Health Foundation, a nonprofit industry partner. Look around, and you will see their slogan appearing everywhere—from colorful logos on plastic produce bags to handouts for public school educational programs. Their hope is to get all Americans to eat at least five servings of fruits and vegetables every day by the year 2000.

The goal is a noble one—no less than the health of the entire nation. The basis of the effort comes from surveys showing that people who get the most vegetables and fruits in their diets have the lowest risk for many illnesses, including cancer and heart disease.

The good news is that most American adults now average about 41/2 servings of fresh produce per day—only a half-serving away from the recommended 5. But children are still lagging behind at only about 3 servings daily. "We don't quite understand why children's consumption of fresh vegetables and fruits hasn't increased in the same way as the adults'," says Linda Nebeling, R.D., Ph.D., nutritionist with the Five a Day for Better Health program. "We are putting a lot of focus now on getting kids to eat just as many fruits and vegetables as their parents do."

Here are some expert tips for fitting in five a day.

Get some decent exposure. Just being around fruits and veggies may make you eat more of them, says Dr. Nebeling. "Put them at eye level in the fridge so that it's the first thing you see when you look in there," she says. And that way your kids will be more likely to crunch a carrot rather than a Clark bar.

Try dried. Dry fruit is an option that many people overlook. Just a quarter-cup raisins or a quarter-cup dried apricots counts as a whole serving of fruit. Keep dried fruit in your desk or send it to lunch in your child's backpack. "It won't go bad on you, and it's a much better choice than those sugary fruit leathers," says Dr. Nebeling.

Make a presentation of it. Stark string beans staring from your plate aren't very exciting. But a cozy bowl of homemade vegetable soup, some steamed Broccoli draped with melted low-fat Cheddar, or a cool blueberry smoothie for breakfast are anything but boring. The challenge is to add fruits and vegetables to your diet in ways that make you want to eat more of them. "We're not just talking about salad here," says Dr. Nebeling.

Do a serving size-up. One serving of vegetables or fruit is a lot smaller than most people think, says Dr. Nebeling. A medium-size banana or apple, a half-cup cut-up fruit, or just a quarter-cup dried fruit all count as a full fruit serving. And a half-cup cooked beans or vegetables, or one cup raw salad greens make the grade as a complete vegetable serving. So, don't think you have to eat truckloads to hit that five-a-day mark, says Dr. Nebeling. And remember, five is a minimum—more servings are even better.

High blood pressure—hypertension—is an even greater risk factor than atherosclerosis, according to the American Heart Association. And controlling blood pressure is the most important way to lower your risk for stroke, says neurologist James L. Napier Jr., M.D., associate clinical professor of medicine at Case Western Reserve University School of Medicine in Cleveland.

Fortunately, blood pressure can often be controlled by eating healthier, the American Heart Association reports, and you don't need to eat boring, tasteless, unsalted food either. But you do need to favor an ideal combination of food.

In a ground-breaking, nationwide diet and hypertension study called the Dietary Approaches to Stop Hypertension (DASH) study, researchers divided nearly 500 adults with and without high blood pressure into three groups and fed each group a different diet. One group ate a typical American diet that was low in fruits and vegetables but accompanied by high-fat dairy products, so the total diet was high in fat content. The second group ate a diet high in fruits and vegetables but skipped the dairy foods. The third group was given a combination diet that was high in fruits, vegetables, and low-fat dairy foods—overall, a low-fat diet with ample dairy in it. Sodium intake averaged about three grams daily in all groups, and all participants maintained their usual weight during the study.

"The combination diet produced striking reductions in blood pressure," says researcher Lawrence J. Appel, M.D., associate professor of medicine, epidemiology, and international health at Johns Hopkins University in Baltimore. All types of people benefited—not just men or women or people of only one race—and within just two weeks of starting the diet. "If all Americans ate this way, the returns could be huge," he concludes.


Top 10 Superfoods to Protect Your Brainpower

To help lower your blood pressure—that all-important factor in warding off stroke—you will want to favor the fruits, vegetables, and low-fat dairy foods that make up an ideal combination diet. Many of these are high in the 6, B12, C, and E—as well as Folate and beta-carotene . An extra advantage to this list is that all of these foods are naturally low in sodium and fat, two important factors to consider in keeping blood pressure low.

So what was it about the DASH way of eating that pushed down the mercury on the blood pressure dial? "We can't be sure, but what we can say is that the diet is very healthy and should be helpful in preventing other medical problems, such as cancer and osteoporosis as well as high blood pressure," says Dr. Appel.

Other research has shown that Potassium Magnesium and Calcium could also play roles in keeping blood pressure down. Potassium may help the body get rid of excess sodium, which can raise blood pressure in salt-sensitive individuals. It may also reduce the urinary loss of Calcium and Magnesium, both of which may also have protective effects on the body. Magnesium may help relax blood vessel walls, which decreases pressure when the heart beats. Calcium contributes to maintaining normal blood pressure by helping to transmit messages from the outside to the inside of cells.

The only catch is actually a bonus: You have to eat real food to get these benefits. "Supplements just don't seem to have the same effect on blood pressure," says Dr. Appel. He believes the difference is explained by the way the minerals and many other health-promoting substances in food work together. It may not be just the minerals; it's possible other substances in food, such as fiber Folate and phytochemicals, may be working together to drive down blood pressure, according to Dr. Appel. To help avoid stroke, he urges people to eat four to five servings of vegetables, four to five servings of fruits, and three servings of nonfat dairy every day. ("And if you are on medication for blood pressure, be sure to take it," Dr. Appel adds. "While diet can control many people's blood pressure, millions of Americans still need to be on drug therapy.")

But of course it's not just stroke that can interfere with clear thinking. As we age, the ability to remember often seems to dwindle. When we're not only losing our keys but also forgetting when we last saw them, we may start to wonder what's up—and how to stop it. And we know intuitively that elderly people who seem youngest in years seem to maintain their memories and brainpower.

Is there any way that the right, nutritious foods can help you keep this fabulous gift of quick, clear thinking as you age? Maybe there is, say researchers at the Jean Mayer U.S. Department of Agriculture Human Nutrition Research Center on Aging at Tufts University in Boston.

Led by former Tufts psychologist Karen M. Riggs, Ph.D., Tufts researchers studied how 70 healthy men age 54 and older performed on tests of mental functioning. Dr. Riggs's team also measured the amount of certain B vitamins that the men had in their bloodstreams and correlated the two bits of information, turning up interesting results. Those men with the lowest levels of Vitamin B12, folic acid , and vitamin B6 did not perform as well on certain mental acuity tests. "While more research is warranted, there is no doubt that everyone should get the current recommended dietary allowance for these three B vitamins ," says Dr. Riggs.

Even more findings implicate food in mind maintenance. Swiss researchers have turned up evidence that people with the highest blood levels of Vitamin C and beta-carotene may also protect their mental functioning and memory. They found that healthy 60-year-olds with the highest blood levels of these important Elsewhere in the world, Dutch researchers uncovered similar findings about beta-carotene and how it protects mental processes involving memory, judgment, perception, and reasoning. Yet another study—this time of Japanese-American men living in Hawaii—points to a role for the antioxidant nutrients Vitamin E and Vitamin C in forestalling losses in mental function.

While research teams are still thinking through why antioxidant foods keep them thinking clearly, they hypothesize that antioxidant nutrients or something else in antioxidant-containing foods may protect fragile brain cells from oxidative damage. This type of damage can break down neurons, which can keep them from properly transferring signals that translate into thinking. Of course, antioxidant nutrients might also keep blood vessels clear so that oxygen-rich blood can flow at full force to the brain cells—also necessary to keep them working their best.


Top 20 Foods for Total Protection

One thing's for sure: If you tried to eat all the foods on the top 10 lists, you would be in for a healthy feast of gargantuan proportions that could help fend off age-related diseases. But many of those foods may be dark leafy greens; high fiber high-nutrient fruits and vegetables; and some whole-grain foods that you rarely shop for. So maybe you'd like a head start on your next shopping list.

That's exactly what you'll find here. This top 20 list is literally the best of the best—the 20 foods that have unquestionable star-quality when it comes to body and mind protection. But, of course, these remarkable 20 won't serve you unless you serve them—not necessarily at every meal but certainly as often as possible. So, along with this highly recommended list, we have also included some suggestions for preparing and serving provided by Kristine Napier, R.D., author of Eat to Heal: The Phytochemical Diet and Nutrition Plan.

The Top 20

1.Spinach. If it's fresh, wash it thoroughly and steam it gently. Or just open a box of frozen spinach and microwave or steam. For extra zest, give each serving a squeeze of fresh lemon. Go for a cup at a time.

2.Nonfat (skim) milk. Get at least two cups daily. If you are used to whole milk or low-fat (1% or 2%) milk, be patient. It might take a while to get used to the taste of skim, but for all the fat calories you save by drinking the nonfat variety, it's worth getting used to.

3. Wheat germ . Sprinkle it on cereal, mix it into quick breads, stir it into Calcium -fortified orange juice.

4. Canned pink salmon with bones. Eat it from the can, add it to salad, or warm it up as salmon loaf.

5.Kidney beans.Open a can, rinse, drain well, and throw those red gems on top of your salad or into chili. If you have the time, cook the beans from scratch.

6.Papaya. Wash, slice, and enjoy.

7.Black-eyed peas. Open a can, rinse, and drain well. Add the peas to soups and stews. Don't hesitate to cook from scratch if you have the inclination.

8.Canned tuna. Always buy the water-packed variety. After you have drained the tuna, add to a salad, or stir into a casserole. If you're making a tuna sandwich, substitute low-fat for high-fat mayonnaise, be sure to use whole-wheat bread, and add a thick slice of tomato.

9. Broccoli. Open a bag of frozen 649">Broccoli and microwave it a very short time. Or buy it fresh and steam it. Enjoy as is, or puree into soup with nonfat milk.

10.Acorn squash. Bake, peel, and mash with nonfat milk and nonfat cream cheese.

11.Tofu. Buy the extra-firm, light variety for stir-fries, and then experiment. tofu picks up the flavor of whatever you put it with. garlic ginger , and tamari are all great complements. Stuff the firm, light variety into lasagna after mixing it with some reduced-fat mozzarella and lots of oregano, basil, and garlic .

12.Bulgur wheat. Don't avoid this incredibly easy-to-prepare food. Just add boiling water, black pepper, and lemon juice. Then cover and let it steam to its golden tenderness in just 30 minutes. Add lots of chopped tomatoes, chopped onions, and just a touch of extra-virgin olive oil for a filling lunch.

13.Whole-wheat bread. Make this the bread staple in your home and use it exclusively. Find a great bread bakery that uses excellent whole-wheat products.
