But not necessarily from the trace amounts of arsenic that people are arguing about.

Despite the government's consideration of new limits on arsenic, nutrition experts say apple juice's real danger is to waistlines and children's teeth. Apple juice has few natural nutrients, lots of calories and, in some cases, more sugar than soda has. It trains a child to like very sweet things, displaces better beverages and foods, and adds to the obesity problem, its critics say.

"It's like sugar water," said Judith Stern, a nutrition professor at the University of California, Davis, who has consulted for candy makers as well as for Weight Watchers. "I won't let my 3-year-old grandson drink apple juice."

Many juices are fortified with vitamins, so they're not just empty calories. But that doesn't appease some nutritionists.

"If it wasn't healthy in the first place, adding vitamins doesn't make it into a health food," and if it causes weight gain, it's not a healthy choice, said Karen Ansel, a registered dietitian in New York and spokeswoman for the American Dietetic Association.

The American Academy of Pediatrics says juice can be part of a healthy diet, but its policy is blunt: "Fruit juice offers no nutritional benefit for infants younger than 6 months" and no benefits over whole fruit for older kids.

Kids under 12 consume 28 percent of all juice and juice drinks, according to the academy. Nationwide, apple juice is second only to orange juice in popularity. Americans slurp 267 ounces of apple juice on average each year, according to the Food Institute's Almanac of Juice Products and the Juice Products Association, a trade group. Lots more is consumed as an ingredient in juice drinks and various foods.

Only 17 percent of the apple juice sold in the U.S. is produced here. The rest comes from other countries, mostly China, Argentina, Chile and Brazil, the association says.

Television's Dr. Mehmet Oz made that a key point a few months ago when he raised an alarm — some say a false alarm — over arsenic in apple juice, based on tests his show commissioned by a private lab. The Food and Drug Administration said that its own tests disagreed and that apple juice is safe.

However, on Wednesday, after Consumer Reports did its own tests on several juice brands and called along with other consumer groups for stricter standards, the FDA said it will examine whether its restrictions on the amount of arsenic allowed in apple juice are stringent enough.

Some forms of arsenic, such as the type found in pesticides, can be toxic and may pose a cancer risk if consumed at high levels or over a long period.

All juice sold in the United States must be safe and meet U.S. standards, said Pat Faison, technical director for the juice association. As for making good nutrition choices, "a lot of the information that people need about fruit juices is on the label," she said.

So what's on those labels?

Carbohydrates, mostly sugars, in a much higher concentration than in milk. Juice has a small amount of protein and minerals and lacks the fiber in whole fruit, the pediatrics academy notes.

Drinking juice delivers a lot of calories quickly so you don't realize how much you've consumed, whereas you would have to eat a lot of apples to get the same amount, and "you would feel much, much more full from the apples," Ansel said.

"Whole fruits are much better for you," said Dr. Frank Greer, a University of Wisconsin, Madison, professor and former head of the pediatrics academy's nutrition committee.

He noted that the WIC program — the U.S. Department of Agriculture's nutrition program for Women, Infants and Children — revised its rules in 2005 to replace juice with baby food fruits and vegetables for children over 6 months. More than half of all infants born in the U.S. are eligible for WIC, and the government "really cut back severely on the ability of mothers to get fruit juices" through the program, Greer said.

If you or your family drinks juice, here is some advice from nutrition experts:

—Choose a juice fortified with calcium and vitamin D-3.

—Give children only pasteurized juice — that's the only type safe from germs that can cause serious disease.

—Don't give juice before 6 months of age, and never put it in bottles or covered cups that allow babies and children to consume it throughout the day, which can cause tooth decay. For the same reason, don't give infants juice at bedtime.

—Limit juice to 4 to 6 ounces per day for children ages 1 to 6, and 8 to 12 ounces for those ages 7 to 18.

—Encourage kids to eat fruit.

—Don't be swayed by healthy-sounding label claims. "No sugar added" doesn't mean it isn't full of naturally occurring sugar. And "cholesterol-free" is silly — only animal products contain cholesterol.

FDA examines level of arsenic in apple juice

AppId is over the quota
AppId is over the quota
WASHINGTON (AP) — The Food and Drug Administration is considering tightening restrictions for the levels of arsenic allowed in apple juice after consumer groups pushed the agency to crack down on the contaminant.

Studies show that apple juice has generally low levels of arsenic, and the government says it is safe to drink. But consumer advocates say the FDA is allowing too much of the chemical — which is sometimes natural, sometimes man made — into apple juices favored by thirsty kids.

There is little consensus on whether these low levels could eventually be harmful, especially to children. Michael Taylor, FDA's deputy commissioner for foods, said Wednesday the agency has already stepped up testing and research on arsenic in apple and other juices and is seriously considering lowering the FDA's so-called "level of concern" for the contaminant.

"We continue to think that apple juice is generally safe based on the fact that the vast majority of samples are very low," Taylor said. "But we want to minimize these exposures as much as we possibly can."

Arsenic is naturally present in water, air, food and soil in the two forms — organic and inorganic. According to the FDA, organic arsenic passes through the body quickly and is essentially harmless. Inorganic arsenic — the type found in pesticides — can be toxic and may pose a cancer risk if consumed at high levels or over a long period.

The FDA uses 23 parts per billion as a guide to judge whether apple juice is contaminated. The agency has the authority to seize apple juice that exceeds those levels, though it has never done so.

Consumer groups say the FDA's level is too high and isn't enforced with enough urgency. Consumers Union, publisher of Consumer Reports, released a study on Wednesday calling for the levels to be as low as 3 parts per billion. The Environmental Protection Agency has set levels for drinking water — it's consumed at much greater quantities than apple juice — at 10 parts per billion.

The Consumer Reports study showed that nine of 88 samples of apple juice taken from grocery stores had more arsenic than the EPA's standard for drinking water. But none of the samples exceeded the FDA's standards for inorganic, or man-made, arsenic.

Urvashi Rangan of the Consumers Union says the group has been in talks with the FDA on the issue and is encouraged by the discussion. Another advocacy group, Food and Water Watch, has lobbied the agency on the issue, and Dr. Mehmet Oz has highlighted the issue on his nationally syndicated daytime show.

"We look at apple and grape juice as a poster child for arsenic in the food supply in general," Rangan said. "Chronic low-level exposure of carcinogen is something we should be concerned about."

Molly Kile, a professor at Oregon State University who has studied arsenic for a decade, says more research is needed to determine whether arsenic levels in juice are a problem.

"It is unclear at this point whether or not the arsenic found in apple juice is safe or unsafe," she said. "And really the question is what do these low levels exposure of arsenic mean in terms of health and children's health?"

So what is the parent of a juice-drinking toddler to do?

All of the experts — including the government and the consumer advocates — agree that drinking small amounts of apple juice isn't harmful. The concern is over the effects of drinking large amounts of juice over long periods of time. Parents with a real concern about arsenic should try to diversify the brands of juice they buy in case one brand tends to have more chemical exposure, Consumers Union says.

Another point of agreement is that children under 6 shouldn't be drinking much juice anyway because it's high in calories. Health experts say children under 6 shouldn't drink any more than 6 ounces of juice a day — about the size of a juice box. Infants under 6 months shouldn't drink any juice at all.

Gail Charnley of the Juice Products Association says the industry regularly tests arsenic levels and will follow the FDA's lead.

"Of course parents have concerns but they should know that the juice producers are committed to safety," she said. "Producers have children who drink juice too."

Oz has said he would still serve juice to his own children, though he strongly believes the government isn't doing enough.

"The absolute safest level for arsenic in your food is zero," he said Wednesday while acknowledging "that is impossible to achieve."

Study: An Apple a Day May Keep Stroke at Bay

AppId is over the quota
AppId is over the quota

Eating white-fleshed fruits like apples and pears was associated with a significant dip in stroke risk, finds a large new study by Dutch researchers.

Although recent studies have touted vibrantly colored fruits and vegetables as being the most healthful — orange sweet potatoes, green kale and bright blueberries, for instance — it was humbly pale-fleshed apples and pears that came out as big winners in the new study.

The researchers analyzed data on more than 20,000 men and women aged 20 to 65, who were healthy and free of cardiovascular disease at the start of the 10-year study. Based on questionnaires filled out by the participants, researchers tracked their intake of fruits and vegetables by color: green (broccoli, kale, spinach and other leafy greens), orange/yellow (citrus fruits, carrots, peaches), red/purple (tomatoes, beets, cherries) and white (apples, including applesauce, pears, bananas, cauliflower, cucumber, chicory).

LIST: 5 Healthier Alternatives to the Potato Chip

Overall, the white category was mostly widely consumed of the color groups, accounting for 36% of all produce eaten. The most common foods in that group were apples, pears and applesauce.

The investigators followed the participants for a decade, logging the number of strokes people suffered. There were 233. When the rate of stroke was compared to the participants' diet, researchers found no association with the amount of brightly colored fruits and veggies they ate, a bit of a surprise considering that the phytochemicals that lend these foods their hue have been linked with good heart health and a lower risk of cancer.

Participants who consumed 171 grams of white-fleshed produce daily, however — the equivalent of one medium to large apple — were 52% less likely to have suffered a stroke than people who ate less than 78 grams of white produce. Overall, for every 25 grams of white fruit consumed each day, participants saw a 9% reduction in stroke risk.

It's not known why white fruits may be associated with such a dramatic effect on stroke, and the authors cautioned that the findings need to be replicated before making any recommendations specifically about white fruits. But it's well known that diets rich in fiber — found in apples and pears — contribute to overall cardiovascular health. And as the Well Blog's Tara Parker-Pope notes: "Both fruits also contain a number of nutrients and phytochemicals, including the flavonol quercetin, which may have anti-inflammatory properties."

Like other research that relies on self-reported questionnaires, the current study is limited by people's potentially faulty recollections about what they ate. Still, the study was large and population based, and tends to support some widely accepted nutritional advice: eating fruits and vegetables is good for your health.

The study was published Thursday in Stroke: Journal of the American Heart Association and was funded by combined grants from Dutch and European public health agencies as well as the Dutch Product Board for Horticulture.

Tempest In A Lunch Box: Arsenic Traces In Apple Juice

Fears over arsenic in apple juice are overblown, experts say.

Fears over arsenic in apple juice are overblown, experts say. iStockphoto.com Fears over arsenic in apple juice are overblown, experts say.

A lot of parents might be worried about what's in their kids' sippy cups if they caught a recent report by TV talk show host Dr. Mehmet Oz about high levels of arsenic in popular brands of apple juice.

But the Food and Drug Administration and medical experts are attacking Oz's report, saying it's inaccurate and needlessly panics parents.

In fact, Dr. Richard Besser, former acting head of the Centers for Disease Control and Prevention, tackled Oz head-on this morning on Good Morning America. Besser, a med school classmate of Oz's, called the report "extremely irresponsible" and compared it to yelling fire in a crowded theater. (Hear their testy exchange here.)

 

Oz found arsenic levels as high as 36 parts per billion (ppb) in some Gerber brand apple juice, and some lower levels in other brands.

But the problem is that Oz's testing only looked at the total arsenic in the apple juice products. The assays didn't distinguish between organic arsenic, which is found in nature and passes through the body quickly, and inorganic arsenic, which can be toxic in large doses and over long periods of time.

"How can you tell people this is harmful without even doing those [separate] tests? No good scientist would ever do that kind of work," Besser fumed at Oz.

Meanwhile, the FDA conducted its own tests, and found significantly lower levels of total arsenic in the same juice. "Moreover, the vast majority of apple juice samples tested by the FDA over that past 20 years show that apple juice typically contains less than 10 ppb total arsenic," the FDA says in a letter to the show. (10 ppbs is the amount the Environmental Protection Agency says is OK in tap water.)

Oz said on GMA that he stands by the test results, and denied he was scaring parents. "I would not take apple juice out of my kids containers right now," Oz, the father of four, said. But it's "misleading to claim that all of the organic arsenic is safe," he said, and he hopes his report will "start a conversation."

So is there reason to worry about arsenic in apple juice?

While Dr. Oz is not the only one whose testing has turned up high levels of arsenic in apple juice, the FDA maintains that it's monitoring apple juice levels and that the drink is safe to consume.

The U.S. banned inorganic arsenic in pesticides in the late 1980s, although some remains in the soil, scientists say. But since most apple juice concentrate now comes from China, where pesticide standards are decidedly less stringent, people are worried about arsenic and other chemicals.

So why isn't there a "safe" level of arsenic in apple juice to protect consumers from long-term exposure?

The FDA says harmful inorganic arsenic is the form regulated in drinking water, whereas organic arsenic is the form mostly found in food, including apple juice.

That's not to say that the FDA takes arsenic lightly. It recently ordered a chicken drug containing arsenic off the market.

Consumer Reports has warned consumers about about high levels of arsenic and other heavy metals found in protein drinks.

HEALTH MANAGEMENT. The FDA takes Dr. Oz Over Apple juice

"This considerable fear, it reminds me yelling fire in a movie theatre."
-Dr. RICHARD BESSER, Health of ABC News and editor in Chief Medical Officer, Dr. Mehmet Oz, television host and contributor of time, the criticism over claims that he made his show Wednesday on the dangers of traces of arsenic in Apple juice. A laboratory hired by the Dr. Oz Show found higher levels of total arsenic in Apple juice that the FDA permits in bottled water - a threat to public health, said of Oz. But in a letter to the show, the FDA called Oz "irresponsible and misleading" claims because the performance of the test does not distinguish between organic and inorganic arsenic, a point key, the Agency said, since only inorganic arsenic are toxic. Bottled water contains more than inorganic arsenic, organic shape is found in foods, including the juice. The FDA, Apple Juice is safe to drink. [via ABC News]
