Corrections
The article "The Diets of American's Children" found on page 6 of the September/October 1997 issue of the Digest contains a misprint. The second bulleted item should read:

• Female adolescents' diets were high in total fat, saturated fat, and sodium. In addition, only a small fraction of female adolescents met the recommended intakes for calcium, dietary fiber, and iron. Low calcium intakes may have serious long-term consequences. The National Academy of Sciences recommends a relatively high allowance of calcium for teenage girls 1,200 milligrams per day—because bone mass develops primarily during the teenage and young adult period.

The article "Gleanings From Diet and Cancer Research" found on page 5 of the September/October 1997 contains an error. The fourth bulleted item, second sentence should read: High coffee intake appears to increase colon cancer risk and high tea intake seems to protect against rectal cancer.

You Asked It—Rapid Response Center Q/A
Q. What is hawthorn?
A. Hawthorn is a tree that produces small, hard fruits that are very hard to cut open. They are about one-inch in diameter and leave a golden stain on the fingers. The fruit is often called a haw.

Q. What is a muffuletta?
A. A specialty of New Orleans, this hero-style sandwich consists of a round loaf of crusty Italian bread, split and filled with layers of sliced provolone, Genoa salami and ham topped with "olive salad," a chopped mixture of green, unstuffed olives, pimientos, celery, garlic, cocktail onions, capers, oregano, parsley, olive oil, redwine vinegar, salt and pepper.

Q. Should I buy one of these "vegetable wash" products to wash my fruits and vegetables?
A. No. At this time, there is no research to indicate that these products are more effective that water for washing fruits and vegetables. Our current recommendation stands: Use cold water and a brush for obviously soiled areas to wash produce.

Q. How do you substitute dill seed for dill head?
A. 3 heads of dill can substitute for 1 tablespoon of dill seed.

Q. If an egg has salmonella in it, is it contained only in the yolk?
A. No, salmonella can live in the yolk and the white of an egg.

Q. Can I use a cucumber variety called "sweet success" for pickles?
A. According to the Horticulture Response Center, "sweet success" is not a pickling variety.

Q. Is the additive used to make decaf coffee more harmful than caffeine?
A. Caffeine used to be extracted out of the coffee using a solvent called methelyne chloride, but its use was called into question because rats given extremely large doses developed cancer. Although still allowed by the FDA, methylene chloride is rarely used.

Q. What do grape leaves do for pickles?
A. Grape leaves contain a substance that inhibits the enzymes that make pickles soft. However, if you remove the blossom end (the source of undesirable enzymes) you don't need to add grape leaves. (RB)

Best Fruits For Antioxidants
Some of the hottest nutrition findings are about the antioxidants in fruits. Newly published research indicates that of twelve fresh fruits, strawberries have the most antioxidant activity. The rest of the fruits in order of potency are plum, orange, red grapes, kiwi fruit, pink grapefruit, white grapes, banana, apple, tomato, pear and melon. Melon has only one fifteenth of the total antioxidant activity of strawberries. Of five fruit juices, the most antioxidant power is in grape juice followed by grapefruit, tomato, orange and apple juices. Grape juice has three times the antioxidant capacity of the next in line, grapefruit juice. Surprisingly, vitamin C only accounts for a very small fraction of the antioxidant potential in these five juices.

One of the earliest reports of the protective effect of fresh fruits and vegetables regarding coronary heart attack was published in 1975. It is now known that free radicals are produced naturally in our bodies as a result of metabolism. These radicals can damage molecules and cells by oxidizing them. Examples of substances that can be oxidized are lipids like cholesterol and fatty acids, proteins in enzymes, nerve cells, and muscles, and nucleic acids that make up the DNA and RNA found in genes. Free radical damage can lead to major chronic diseases including all common cancers, coronary heart attacks from atherosclerosis, and strokes from cerebrovascular disease. Thus, antioxidants from food that neutralize these free radicals are important in preventing these diseases.

Vitamins C, E and beta-carotene are well known for their antioxidant activity, but using separate or single vitamin supplements has not been as effective in preventing or treating heart disease, cancer and stroke as researchers had hoped. In fact, vitamin C and beta-carotene supplements have been associated in some cases with more severe disease and higher death rates.

It wasn't until the 1990s that it became clear that there are many antioxidants beside nutrients in fruits and vegetables that are protective. These antioxidants include a number of flavonoids including flavones, isoflavones, flavanones, anthocyanins, catechin and isocatechin. Besides promoting health, these substances add color, and other qualities to fruits and vegetables. But flavonoids are more than antioxidants. They have also been shown to be antiinflammatory, antiallergic, anticancer and antihemorrhagic.

Researchers have been trying to measure the total antioxidant activity in various fruits and vegetables but it wasn't until two years ago that they developed the test, the ORAC assay, for total antioxidant activity. This was accomplished by researchers from the Jean Mayer Human Nutrition Research Center on Aging at Tufts University, Agricultural Research Service, U.S. Department of Agriculture in Boston, and the Nutritional Science Department, University of Connecticut at Storrs.

No supplements presently available contain all of the antioxidants available in fruits and vegetables. Nor are they in balance with each other for in certain situations supplements could actually do more harm than good. If such a balanced supplement is manufactured some day, it would be sold at a far higher price than what it costs to buy the antioxidants naturally in fruits and vegetables. So to keep healthy, follow the Food Guide Pyramid advice and get at least two servings of fruit and juice every day! (MC)

The Diets of America's Children, Part 2
In the last issue of the Digest, data were presented from the USDA's 1989-1991 Continuing Survey of Food Intakes by Individuals and the Diet and Health Knowledge Survey that outlined several shortfalls in the diets of American children. (See Foods and Nutrition Digest, September/October, and correction on page 1 of this issue.) But that is only the beginning of the story. A closer look by researchers at Pennsylvania State University at the diets of the 3,307 US youths, aged two to 19 who were included in the survey, reveals some more disturbing trends.

A low percentage of the children were meeting the Food Guide Pyramid recommendations for any of the food groups:

• 31.6% follow the guideline of eating 6-11 serving of grain per day
• 26% consume 2-4 servings of fruit
• 28% eat 5-7 ounces of meat
• 36.4% consume 3-5 servings of vegetables
• 33% consume 2-3 servings of dairy products

Patterns of consumption varied according to gender and age. Children of both sexes were more likely to eat the recommended amounts of meats and vegetables as they grew older and less likely to eat the recommended amounts of fruit. Adolescent males (ages 12-19) had higher average intakes of grains, vegetables, dairy and meats compared to all other age and gender groups and they were least likely to fall into the pattern of not meeting any of the recommendations. But younger children and adolescent females exceeded the adolescent male in consumption of fruit. Unfortunately for the adolescent females, they seemed to be eating more fruit because they were dieting. Their energy intakes were very low.

There were also differences in consumption among racial groups. White children were more likely to meet the recommendations for grains and dairy than were either black or Hispanic children. White children were less likely than black children to meet the recommendations for vegetables.

And income was another factor associated with the quality of children's diets. Children from lower income families had lower intakes and more often did not meet the recommendations for fruit or dairy. (PP)
