Soda a day may see 20% rise in heart attack risk

Soft Drinks
MUMBAI: Tempting as it may be due to rising mercury levels but people having fizzy drinks daily are at 20% higher risk of getting heart disease than those who don't, a new study suggests. Also, people who drink diet sodas every day have a 61% higher risk of bursting a blood vessel. What is alarming is that even children, who consume 40-70 ml of soft drinks a day, may put on 3-5 kilos every year.

"Youngsters don't drink water but readily gulp down colas. They have to be told that what you do when you are a 10-year-old shows on your heart when you are 40 years old," says heart surgeon Dr Ramakanta Panda of Asian Heart Institute in Bandra Kurla Complex. And that for Mumbai's doctors is a worrying factor, as children in Indian cities are getting increasingly hooked on to soft drinks.

"The intake could have gone up to 100 ml a day now," says Dr Anoop Mishra, an endocrinologist with Fortis Hospital in Delhi, who conducted the study for Delhi-based Diabetes Foundation three years ago.

But what makes soft drinks such a health hazard is that taking a cola a day is equivalent to having seven to eight spoons of sugar at a time, says Dr Shashank Joshi, an endocrinologist with Lilavati Hospital in Bandra. The carbohydrates or sugars only provide empty calories without any nutrition, merely adding to one's weight. "It's a well-documented fact that sugary soft drinks lead to high cholesterol, high blood pressure and diabetes," he says.

The latest study from Harvard School of Public Health in Boston shows sugary drinks hit men's heart hard. The diet and health habits of 43,000 men were followed from 1986 to 2008, showing that 3,683 men who had sugary beverage every day had coronary heart disease in comparison to those who didn't.

Another study from the University of Sydney found that children who drank one or more soft drinks each day had narrower arteries in the back portion of their eye- a factor linked to higher risk of heart disease and high blood pressure.

Doctors believe it's time society adopted a hard stance against soft drinks. Dr Panda is tying with an NGO to create health awareness in school. Dr Joshi believes it's time to ban soft drinks from homes and schools, while Dr Mishra says soft drinks' consumption should be restricted to once or twice a week.

Dr Jagmeet Madan, who heads SNDT University's Nutrition College, says that children are discerning enough to understand when told that empty calories found in colas is bad. "We can tell them that there are 'sometime foods' and 'everytime foods'. It is only when 'sometime foods' like colas become 'everytime foods' that the problem arises," she adds.

A paper published in this week's American Journal of Nutrition provides a heartening observation. The article by researchers of University of North Carolina at Chapel Hill hints that a person's overall diet may decide just how harmful is the soft drink-a-day routine. It found that people who had a prudent diet (freshly cooked meals) had lowest risk of heart diseases in comparison to people who eat processed food (including meat) along with soft drinks every day. "One should physically work the effects of a sugary drink off," adds Dr Mishra.

8 of the World’s Healthiest Spices & Herbs You Should Be Eating

As a registered dietitian and associate nutrition editor at EatingWell Magazine, I know that herbs and spices do more than simply add flavor to food. They let you cut down on some less-healthy ingredients, such as salt, added sugars and saturated fat, and some have inherent health benefits, many of which Joyce Hendley reported on for EatingWell Magazine.

Modern science is beginning to uncover the ultimate power of spices and herbs, as weapons against illnesses from cancer to Alzheimer's disease. "We're now starting to see a scientific basis for why people have been using spices medicinally for thousands of years," says Bharat Aggarwal, Ph.D., professor at the University of Texas M.D. Anderson Cancer Center in Houston and author of Healing Spices (Sterling, 2011).

Aggarwal notes that in his native India, where spices tend to be used by the handful, incidence of diet-related diseases like heart disease and cancer have long been low. But when Indians move away and adopt more Westernized eating patterns, their rates of those diseases rise. While researchers usually blame the meatier, fattier nature of Western diets, Aggarwal and other experts believe that herbs and spices-or more precisely, the lack of them-are also an important piece of the dietary puzzle. "When Indians eat more Westernized foods, they're getting much fewer spices than their traditional diet contains," he explains. "They lose the protection those spices are conveying."

While science has yet to show that any spice cures disease, there's compelling evidence that several may help manage some chronic conditions (though it's always smart to talk with your doctor). What's not to love? Here we've gathered eight of the healthiest spices and herbs enjoyed around the world.

Chile Peppers
May help: Boost metabolism.
Chile peppers add a much-appreciated heat to chilly-weather dishes, and they can also give a boost to your metabolism. Thank capsaicin, the compound that gives fresh chiles, and spices including cayenne and chipotle, their kick. Studies show that capsaicin can increase the body's metabolic rate (causing one to burn more calories) and may stimulate brain chemicals that help us feel less hungry. In fact, one study found that people ate 16 percent fewer calories at a meal if they'd sipped a hot-pepper-spiked tomato juice (vs. plain tomato juice) half an hour earlier. Recent research found that capsinoids, similar but gentler chemicals found in milder chile hybrids, have the same effects-so even tamer sweet paprika packs a healthy punch. Capsaicin may also lower risk of ulcers by boosting the ability of stomach cells to resist infection by ulcer-causing bacteria and help the heart by keeping "bad" LDL cholesterol from turning into a more lethal, artery-clogging form.

Ginger
May help: Soothe an upset stomach, fight arthritis pain.
Ginger has a well-deserved reputation for relieving an unsettled stomach. Studies show ginger extracts can help reduce nausea caused by morning sickness or following surgery or chemotherapy, though it's less effective for motion sickness. But ginger is also packed with inflammation-fighting compounds, such as gingerols, which some experts believe may hold promise in fighting some cancers and may reduce the aches of osteoarthritis and soothe sore muscles. In a recent study, people who took ginger capsules daily for 11 days reported 25 percent less muscle pain when they performed exercises designed to strain their muscles (compared with a similar group taking placebo capsules). Another study found that ginger-extract injections helped relieve osteoarthritis pain of the knee.

Cinnamon
May help: Stabilize blood sugar.
A few studies suggest that adding cinnamon to food-up to a teaspoon a day, usually given in capsule form-might help people with type 2 diabetes better control their blood sugar, by lowering post-meal blood-sugar spikes. Other studies suggest the effects are limited at best.

Turmeric
May help: Quell inflammation, inhibit tumors.
Turmeric, the goldenrod-colored spice, is used in India to help wounds heal (it's applied as a paste); it's also made into a tea to relieve colds and respiratory problems. Modern medicine confirms some solid-gold health benefits as well; most are associated with curcumin, a compound in turmeric that has potent antioxidant and anti-inflammatory properties. Curcumin has been shown to help relieve pain of arthritis, injuries and dental procedures; it's also being studied for its potential in managing heart disease, diabetes and Alzheimer's disease. Researcher Bharat Aggarwal is bullish on curcumin's potential as a cancer treatment, particularly in colon, prostate and breast cancers; preliminary studies have found that curcumin can inhibit tumor cell growth and suppress enzymes that activate carcinogens.

Saffron
May help: Lift your mood.
Saffron has long been used in traditional Persian medicine as a mood lifter, usually steeped into a medicinal tea or used to prepare rice. Research from Iran's Roozbeh Psychiatric Hospital at Tehran University of Medical Sciences has found that saffron may help to relieve symptoms of premenstrual syndrome (PMS) and depression. In one study, 75% of women with PMS who were given saffron capsules daily reported that their PMS symptoms (such as mood swings and depression) declined by at least half, compared with only 8 percent of women who didn't take saffron.

Parsley
May help: Inhibit breast cancer-cell growth.
University of Missouri scientists found that this herb can actually inhibit breast cancer-cell growth, reported Holly Pevzner in the September/October 2011 issue of EatingWell Magazine. In the study, animals that were given apigenin, a compound abundant in parsley (and in celery), boosted their resistance to developing cancerous tumors. Experts recommend adding a couple pinches of minced fresh parsley to your dishes daily.

Sage
May help: Preserve memory, soothe sore throats.
Herbalists recommend sipping sage tea for upset stomachs and sore throats, a remedy supported by one study that found spraying sore throats with a sage solution gave effective pain relief. And preliminary research suggests the herb may improve some symptoms of early Alzheimer's disease by preventing a key enzyme from destroying acetylcholine, a brain chemical involved in memory and learning. In another study, college students who took sage extracts in capsule form performed significantly better on memory tests, and their moods improved.

Rosemary
May help: Enhance mental focus, fight foodborne bacteria.
One recent study found that people performed better on memory and alertness tests when mists of aromatic rosemary oil were piped into their study cubicles. Rosemary is often used in marinades for meats and poultry, and there's scientific wisdom behind that tradition: rosmarinic acid and other antioxidant compounds in the herb fight bacteria and prevent meat from spoiling, and may even make cooked meats healthier. In March 2010, Kansas State University researchers reported that adding rosemary extracts to ground beef helped prevent the formation of heterocyclic amines (HCAs)-cancer-causing compounds produced when meats are grilled, broiled or fried.

Soaring BPA Levels Found in People Who Eat Canned Foods

Eating canned food every day may raise the levels of the compound bisphenol A (BPA) in a person's urine more than previously suspected, a new study suggests.

People who ate a serving of canned soup every day for five days had BPA levels of 20.8 micrograms per liter of urine, whereas people who instead ate fresh soup had levels of 1.1 micrograms per liter, according to the study. BPA is found in many canned foods — it is a byproduct of the chemicals used to prevent corrosion.

When the researchers looked at the rise in BPA levels seen in the average participant who ate canned soup compared with those who ate fresh soup, they found a 1,221 percent jump.

"To see an increase in this magnitude was quite surprising," said study leader Karin Michels, an associate professor of epidemiology at the Harvard School of Public Health.

The levels of BPA seen in the study participants "are among the most extreme reported in a nonoccupational setting," the researchers wrote in their study. In the general population, levels have been found to be around 1 to 2 micrograms per liter, Michels said.

The study noted that levels higher than 13 micrograms per liter were found in only the top 5 percent of participants in the National Health and Examination Survey, which is an ongoing study conducted by the Centers for Disease Control and Prevention.

"We are concerned about the influence of [hormone-disrupting] chemicals on health in general, and BPA is one of them," Michels told MyHealthNewsDaily.

The study is published online today (Nov. 22) in the Journal of the American Medical Association.

Soup for lunch

The study included 75 people, whose average age was 27. One group of participants ate 12 ounces of fresh soup every day at lunchtime, while the other ate the same amount of canned soup each day. Urine samples were collected from the participants on the fourth and fifth days of the study.

BPA was detected in 77 percent of people who ate the fresh soup, and all of the people who ate the canned soup, according to the study.

Only a few studies had previously looked at BPA levels from eating canned foods, and those relied on asking people how much of the food they usually eat comes from cans, Michels said. The new study was the first in which researchers randomized participants to eat a small serving of canned food or fresh food, and measured the resulting difference in their urine BPA levels, she said.

"We've known for a while that drinking beverages that have been stored in certain hard plastics can increase the amount of BPA in your body. This study suggests that canned foods may be an even greater concern, especially given their wide use," said study researcher Jenny Carwile, a doctoral student at Harvard.

BPA and health

A 2008 study of 1,455 people showed that higher urinary BPA levels were linked with higher risks of developing cardiovascular disease and diabetes, and abnormal concentrations of certain liver enzymes, even after factors such as age, body mass index and smoking were taken into account.

And other studies have linked BPA levels in a woman's urine during her pregnancy to health problems in her child.

It is not known how long the levels of BPA might remain high, according to the study. However, it is also not known whether such a spike, even if it isn't sustained for very long, may affect health, the researchers wrote.

The study was limited in that all of the participants were students or staff at one school, and a single soup brand (Progresso) was tested, but the researchers wrote that they expected the results to apply to canned foods with a similar BPA content.

"Reducing canned food consumption may be a good idea, especially for people consuming foods from cans regularly," Michels said. "Maybe manufacturers can take the step of taking BPA out of the lining of cans — some have already done this, but only a few."

The study was funded by the Allen Foundation, which advocates nutrition research.
