Power Up Your Diet

Health.com: Top 10 Superfoods for Spring

There's a food movement afoot: Eating well to look, feel, and perform our very best is hot. And as Jamie Oliver and Michelle Obama alike are showing us, this isn't a matter of choking down foods because they're good for you. It's about filling your plate with delicious fare.

"Food, if it's chosen well, can reshape our medical destinies for the better," says David Katz, MD, director of the Yale Prevention Research Center. It can also improve our mood, focus, energy, skin, and metabolism. Here's how to graze your way to a supercharged you.

Walnuts

Good for: Mood

Walnuts are packed with tryptophan, an amino acid your body needs to create the feel-great chemical serotonin. (In fact, Spanish researchers found that walnut eaters have higher levels of this natural mood-regulator.) Another perk: "They're digested slowly," Dr. Katz says. "This contributes to mood stability and can help you tolerate stress."

Asparagus

Good for: Mood

These spears are one of the best veggie sources of folate, a B vitamin that could help keep you out of a slump. "Folate is important for the synthesis of the neurotransmitters dopamine, serotonin, and norepinephrine," says David Mischoulon, MD, a psychiatrist at Harvard Medical School. All of these are crucial for mood.

A cup of cooked asparagus has 268 micrograms (mcg)—two-thirds of the 400 mcg RDA for women. Add a cup of enriched pasta—which is fortified with folic acid, the synthetic form of folate—and you'll have a feel-good meal indeed.

Spring Garlic

Good for: Weight Loss

The slim-you benefit of this seasonal treat lies in a compound called allicin, which gives garlic its pungent smell. "Allicin may keep you from overeating by stimulating satiety in the brain," says Tara Gidus, RD, a dietitian in Orlando, Florida.

Spring garlic has a milder, sweeter taste than the dried white bulbs you buy later in the season. Enjoy it diced on salad for a fat-fighting side or lunch.

Legumes

Good for: Weight Loss

Beans are one of your best bets if you're trying to drop pounds, says Joseph Colella, MD, a bariatric surgeon at Magee-Womens Hospital in Pittsburgh. "Your body has to work to break down the bean to get through the fiber," he explains, "so you're actually expending energy to digest it."

Even better, Dr. Colella says, the protein in legumes activates an "I'm satisfied" message in the hunger center of your brain.

Spinach

Good for: Energy

These tasty leaves are a great source of iron (especially if you don't eat meat), which is a key component in red blood cells that fuel our muscles with oxygen for energy.

Researchers in Sweden recently identified another way in which these greens might keep you charged: Compounds found in spinach actually increase the efficiency of our mitochondria, the energy-producing factories inside our cells. That means eating a cup of cooked spinach a day may give you more lasting power on the elliptical machine (or in your daily sprint to catch the bus).

Artichokes

Good for: Energy

If you've been huffing and puffing up the stairs, try these spiky-leafed vegetables. They're loaded with magnesium, a mineral vital for more than 300 biochemical reactions in the body—including generating energy, says Forrest Nielsen, PhD, a U.S. Department of Agriculture research nutritionist. "If you're not getting enough magnesium, your muscles have to work harder to react and you tire more quickly."

About 68% of us aren't getting enough of this mineral. For women, the goal is 320 milligrams (mg) per day. One medium artichoke provides 77 mg of magnesium (and just 60 calories!). Other top sources include nuts, legumes, and whole grains.

Salmon

Good for: Skin

There's wrinkle prevention on your plate: "Salmon is rich in a fatty acid called eicosapentaenoic acid (EPA), a type of omega-3 that naturally helps block the release of UV-induced enzymes that diminish collagen, causing lines and sagging skin," says Ariel Ostad, MD, a dermatologist in New York City.

Bonus: Omega-3s also regulate oil production in the skin and boost hydration, which helps keep your complexion dewy and acne-free.

Strawberries

Good for: Skin

They may not have the smoothest complexion themselves, but strawberries can get you one. They're loaded with antioxidants that help your skin repair damage caused by environmental factors like pollution and UV rays. Plus, they're packed with vitamin C (less than a cup gets you your entire 75 mg RDA)—the vitamin associated with fewer wrinkles and less dryness, per research in the "American Journal of Clinical Nutrition."

Try them in a homemade facial, too. "Direct application of the antioxidants in strawberries—as well as the natural exfoliant they contain, alpha-hydroxy acid—will give you great results," Dr. Ostad says.

Eggs

Good for: Memory

Have your over-easies before you hit the Easter egg hunt. The yolks are chock-full of choline, a key nutrient for recall. "Your body needs choline to make a brain chemical called acetylcholine, crucial for storing memories," says Steven Zeisel, MD, director of the Nutrition Research Institute at the University of North Carolina at Chapel Hill.

The recommended dietary allowance (RDA) for choline is 425 mg. There are 147 mg in a large egg; other good options are nuts and red meat.

Blueberries

Good for: Memory

Eat them regularly and you may reap big brain benefits. In a recent study, people with age-related memory decline who drank roughly two and a half cups of blueberry juice per day for 12 weeks (the equivalent of eating a cup of blueberries) made significant improvements on memory and learning tests compared with those who drank a placebo juice.

The secret component? A type of antioxidant called anthocyanins, says study co-author Robert Krikorian, PhD, a psychologist at the University of Cincinnati: "Anthocyanins have been shown in animal studies to increase signals among brain cells and improve their resilience, enhancing learning and memory."
