A new study finds that drinking orange juice, soda and other beverages high in the sugar fructose could increase the small risk that middle-age and elderly women have of developing gout. Gout is a painful form of arthritis caused by too much uric acid in the blood. For women in the study who drank two or more servings of these beverages per day, the risk of gout was more than double that for women who drank sugary sodas and juices less than once per month. Because gout is relatively rare among women, the drinks probably contribute only moderately to a woman's chances of developing it. Still, this is the first study linking sodas and sweetened fruit juices to women's gout risk. Previous research found such a link for men.
The study will be published in the Nov. 24 issue of the Journal of the American Medical Association, and is being presented today (Nov. 10) at the American College of Rheumatology annual scientific meeting.
Gout occurs when levels of uric acid in the blood become too high, and uric acid crystallizes around the joints, leading to inflammation, swelling and pain. Foods than can increase the levels of uric acid in the blood include organ meats (such as kidneys and livers), asparagus and mushrooms, according to the Mayo Clinic. Fructose is also known to increase blood uric acid levels, the researchers said. While gout is not common in the United States, the rate of incidences has more than doubled over a 20-year period, from 16 cases per 100,000 Americans in 1977 to 42 per 100,000 in 1996. Over this period, the researchers noted, the population also consumed increasing amounts of soda and other drinks sweetened with fructose.
The new study followed 78,906 women for 22 years, from 1984 to 2006, as part of the Nurses' Health Study. At the beginning of the study, none of the women had gout. By the end, 778 had developed it. Women who drank one serving of soda per day were 1.74 times more likely to develop gout than those who drank less than one serving per month. Those who drank two or more servings per day were 2.4 times more likely to develop gout. Drinking two or more servings of soda per day caused an additional 68 cases of gout per 100,000 women per year, compared with drinking less than one serving of soda per month, the researchers said. Drinking orange juice also increased the risk. Women who drank one serving of orange juice per day were 1.41 times more likely to develop gout, and those who drank two or more servings were 2.4 times more likely to report gout.
Lifestyle and diet
The rise in gout cases is most likely due to changes in lifestyle and diet and an increase in conditions associated with gout, such as metabolic syndrome, said study researcher Dr. Hyon K. Choi of the Boston University School of Medicine. The results held even after the researchers took into account factors that could have influenced the findings, such as age, body mass index and whether the women had gone through menopause, Choi said.
The findings suggest diets to prevent gout should reduce fructose intake, the researchers said.
The study was funded by the National Institutes of Health.
Eating red meat and processed meats like bacon sharply increased heart disease risk in women, U.S. researchers say.Researchers at Harvard School of Public Health in Boston suggest eating healthier protein-rich foods — such as fish, poultry, low-fat dairy and nuts — instead of red and processed meats, may reduce heart disease risk.
“There are good protein-rich sources that do not involve red meat,” first author Dr. Adam Bernstein says in a statement. “You don't need to have hot dogs, hamburgers, bologna or pastrami, which are all fresh or processed meats.”
The study, published in the journal Circulation: Journal of the American Heart Association, finds women having two servings per day of red meat had a 30 percent higher risk of developing coronary heart disease than those who had half a serving per day.
The risk of heart disease was lowered 30 percent when a daily serving of red meat was replaced by nuts. Another red-meat replacement — fish — lowered cardiac risk 24 percent and poultry reduced heart risk by 19 percent.
Bernstein and colleagues examined medical history and lifestyle — including diet — for 84,136 women, ages 30-55, enrolled the Nurses' Health Study from 1980 to 2006. During the 26-year period, the researchers documented 2,210 non-fatal heart attacks and 952 deaths from coronary heart disease.
Let’s look at some examples:
You eat 2 waffles for breakfast
- One serving from the Food Guide Pyramid is equal to 1 waffle.
- So that means if you ate 2 waffles, you also ate 2 servings from the grains group.
Here are some other common portions and their respective Food Guide Pyramid serving sizes:
|Common portions that people eat
||Food Guide Pyramid Serving Size
||Total servings per Food Guide Pyramid
||= 2 servings
|1 English Muffin
||½ English muffin
||= 2 servings
|1 Hamburger bun
||= 2 servings
|1 cup cooked rice
||½ cup cooked rice

Try these ideas to help control portions at home:
- When your child is hungry and looking for a snack take the amount of food that is equal to one serving (refer to the Nutrition Facts label) and have your child eat it off a plate instead of eating it out of the box or bag.
- Don’t be tempted to finish off leftover dinner the next day. Freeze leftovers as single servings so that you can pull it out of the freezer when you need a quick, healthy meal for your family.
- Be prepared and have emergency snacks on hand if your family is running late and needs a quick snack. Make your own snack bags for traveling by reading the Nutrition Facts label and placing a single serving size into plastic bags.
- Have your child measure out a single serving of food before sitting in front of the television or doing other activities that can distract him/her from realizing how much food is being consumed. This way your child will know exactly how much he or she is eating!
Serving sizes on food labels are sometimes different from the Food Guide Pyramid servings. For example, the serving size for beverages is measured in cups or fluid ounces. Whether it is milk, juice, or soda the nutrition facts labeling guidelines is 1 cup or 8 fluid ounces, which equals 1 serving size. However, the Food Guide Pyramid serving size for milk is 1 cup, but for juice it is ¾ cup.
So, even though the amount of 1 serving on nutrition facts labels and the Food Guide Pyramid may be slightly different it is still a great tool to help you and your child decide if you are getting enough or too much food each day. Encourage your child to get familiar with the serving sizes because smart eating is an essential part of growing and staying healthy!

The lead author of the latest research, Joan Sabaté, says the study “confirms that nuts, indeed, lower cholesterol.” A professor and the chairman of the department of nutrition at Loma Linda University, in Loma Linda, Calif., Dr. Sabaté was among the group of researchers that first linked nut consumption to a lower risk of heart attack several years ago.
That finding and others led the Food and Drug Administration in 2003 to allow processors to state on labels that “eating 1.5 ounces per day of most nuts … as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.”
Dr. Sabaté said the research indicated that for the average person, a slightly higher amount of nuts—about 2.4 ounces, or two servings—does a better job than one serving of lowering cholesterol and triglycerides, another type of fat in the blood.
Still, he said, “we do not need many to get the benefit.” One serving of almonds is about eight nuts; a serving of smaller nuts such as peanuts is about 15 to 20 nuts.
Dr. Sabaté's analysis involved nearly 600 people with high or normal blood cholesterol levels. None of the study participants were taking cholesterol-lowering medications.
The analysis compared a control group with two groups assigned to consume two different quantities of nuts.
People in one of the nut groups consumed an average of 67 grams of nuts, or about 2.4 ounces, per day.
These people had an average reduction in total blood cholesterol concentration of 5.1%, and a reduction in low-density lipoprotein, or so-called LDL or “bad” cholesterol, of 7.4%.
For the people who consumed about 1.5 ounces of nuts, total cholesterol fell by 3.2%, while “bad” cholesterol fell by 4.9%—suggesting a dose-related response.
Those who consumed about one ounce daily of nuts, total cholesterol fell by 2.8% while LDL cholesterol fell by 4.2%.
Significantly, however, the drops in cholesterol weren't seen in people considered obese—a new finding.
More studies are needed to understand why nuts are less effective at lowering blood cholesterol concentration among obese people, the researchers said.
Dr. Sabaté said the biggest improvement in blood lipid levels were seen among people who started out with higher cholesterol levels, as well as among those who consumed a “Western” diet of high-fat meats, dairy products and refined grains, compared with people consuming a “Mediterranean” diet emphasizing whole grains, lots of fruits and vegetables, fish and relatively little red meat.
“For the general population consuming a Western diet, the incorporation of nuts into their daily diet will result in greater improvement of blood lipid levels than for individuals already following a healthy Mediterranean or low-fat diet,” researchers wrote.
Of the 25 studies, about two-thirds of them involved almonds or walnuts. The other one-third of studies looked at either macadamia, pistachio, hazelnuts or peanuts. The studies didn't include pine nuts or Brazil nuts.
The study was funded by Loma Linda University in California and by the International Tree Nut Council Nutrition Research and Education Foundation, an international group that represents the tree nut industry.
Can eating less be as simple as leaving serving dishes on the stove and off the table? According to a team of researchers from Cornell University, it can.
At this week's Experimental Biology conference in Anaheim, Calif., researchers led by Brian Wansink, director of the Cornell Food and Brand Lab, shared findings of their “Serve Here; Eat There” study of 78 adults.
“We looked at whether serving foods from the kitchen counter, instead of at the table, would reduce the number of times a person refilled his or her plate,” Wansink said.
“Quite simply, it is a case of 'out of sight, out of mind,'” he continued. “When we kept the serving dishes off the table, people ate 20% fewer calories. Men ate close to 29% less.”
The same strategy can be used to help increase the consumption of healthier foods, Wansink explained.
“If fruits and vegetables are kept in plain sight, we'll be much more likely to choose them, rather than a piece of cake hidden in the refrigerator.”
Dining environment, plate and portion size, and other hidden cues that determine what, when and how much we eat are familiar topics in Wansink's work. He is the author of Mindless Eating: Why We Eat More Than We Think.
