Healthy Living in the Real World (cont.)

Those are the guidelines. But don't fall into the trap of an all-or-nothing approach. You may have more success if you add one healthy habit at a time. Read on for specific suggestions in each category.

To get the most out of your diet, American Dietetic Association spokesman Dave Grotto, RD, says the key is to focus on the "creme de la creme" of each food group. "I advise a United Nations approach to eating vegetables," Grotto tells WebMD. "You want the greatest variety and intensity of color." For example, sweet potatoes, squash, and deep ruby-red tomatoes. The same goes for fruits. Look for berries, cherries, and pomegranates. Buy them dried or frozen when they're out of season.

As for grains, Grotto says the most nutritious are those "that have the word 'whole' in the first ingredient." See the chart below for more examples of foods that give you the biggest bang for your bite.

  Examples of Optimum Foods in Each Group
Grains Whole grains with 3+ grams of fiber per serving
Vegetables The more intense the color, the better (tomatoes, spinach, sweet potatoes, squash)
Fruits The more intense the color, the better (berries, cherries, pomegranates)
Meats/Proteins Foods rich in omega-3 fats (fish, wild game)
Lean meats
Plant-based proteins (tofu, beans, legumes)
Fats Nuts, seeds, olive oil

Oral Hygiene

Cleaning your teeth by brushing alone is like trying to "vacuum the whole house without attachments," says American Dental Association spokesman Richard Price, DDS. "You need something to get between the crevices."

That means flossing. "What you're doing with the floss is physically removing the plaque that the toothbrush can't reach," Price tells WebMD. "If you find it difficult, try a Teflon type that slips between the teeth easily. If it breaks and shreds, there's something rough between the teeth," a sign that it's time to see your dentist.

If you only have time to do one thing for your skin, what should it be? "Sunscreen, sunscreen, sunscreen," answers dermatologist Robin Ashinoff, MD. "Year-round sunscreen. It is the one thing that will protect your skin. I recommend a minimum of SPF 30."

If you have time for more than sunscreen, try a topical retinoid to reduce acne and the appearance of fine lines, wrinkles, and age spots. Ashinoff, who is the director of Dermatologic Mohs and Laser Surgery at Hackensack University Medical Center, tells WebMD, "Retinoids increase collagen, promote skin turnover, even out skin tone and have anticancer effects." She recommends prescription-strength retinoids but says over-the-counter formulas can also be effective.
