Nutritionally Speaking

Fruits, Vegetables Are the Focus of Five-a-Day Plan

April 06, 1989|TONI TIPTON

To improve the public's eating habits, health agencies continue to provide nutritional messages that they hope will be understandable and easy to remember. This time the message pertains to eating one's vegetables.

Last summer, the state's Department of Health Services announced a new Nutrition and Cancer Prevention Program designed to reduce chronic diseases related to dietary excess and imbalance. Designated the "Five a Day--For Better Health" program, it encouraged Californians to eat at least five servings of fruits and vegetables per day. Although this is one more than the amount recommended in the government's Four Food Group Plan, a standard measurement of dietary adequacy, it was expected to make eating vegetables a tangible goal.

More recently, the same advice was offered by the National Research Council, a branch of the National Academy of Sciences, which made a similar statement in a report issued last month. In a summary of the report, the NRC encouraged Americans to "eat five or more one-half cup servings a day of a combination of vegetables and fruits, especially green and yellow vegetables and citrus fruits."

While fresh varieties of fruits and vegetables such as apples, pears, cantaloupes, berries, citrus, carrots, broccoli, cabbage, green beans, squash, peas, spinach, kale and other greens, yams and turnips are typically preferred, frozen can be acceptable alternatives for fresh, which lose nutrients when left unattended for days in the refrigerator before being consumed, according to a spokesperson from the "Five a Day" campaign.

Dried Produce Acceptable

"Dried, frozen and canned vegetables, provided they have no added fat or sugar source and contain fewer than 140 milligrams sodium, are acceptable," said Brian Krieg, the campaign's director of marketing, adding that choosing the frozen variety is a "great way" to meet the recommendation. "The frozen is almost identical (to fresh) in nutrients. . . . There's no nutrient loss--it's microscopic."

Rita Storey, registered dietitian and spokesperson for the American Dietetic Assn., agreed. She said that vegetables frozen near the harvesting site have a loss of nutrients that is "very minimal." In some cases, she said, frozen can be more nutritious, depending upon how long it takes for the fresh vegetables to get to the dinner table.

"Fresh food, obviously, is always preferred," said Storey, adding that vegetables should be kept frozen from the supermarket to home and frozen immediately.

They are often more nutritious than items that are purchased fresh, then left in the refrigerator a few days. Produce destined for freezing is blanched and frozen within four to six hours after it is picked. This locks in its freshness and flavor, while fresh produce is often harvested early, then allowed to ripen off the vine as it travels to market. This contributes to nutrient and flavor loss, according to the Frozen Food Council.

Things to Keep in Mind

Here are some tips, from the council, to keep in mind when opting for frozen vegetables to meet the desired goal of three to five vegetable servings per day:

--Feel the package. If the vegetables are clumped together, they have been thawed and refrozen, resulting in a loss of quality.

--If the packaging is clear, there should be no crystallization--another sign of thawing and refreezing.

--At the check-out counter, make sure all frozen items are packed together to keep them cold, and head straight home.

--At home, put the frozen items into the freezer immediately. They stay fresh longer at zero degrees--up to six months. Use vegetables stored at 15 degrees within four weeks.

--Pack frozen vegetables loosely in the freezer and store opened packages airtight to prevent freezer burn.

--Use the microwave oven for preparation. Microwaving uses less water than conventional methods, which preserves nutrients that would otherwise be leeched out into the cooking liquid. It also requires no fat to prevent sticking.
