Potatoes can add plenty to waistline
#1
   

Public Enemy No. 1 in America's battle of the bulge isn't cupcakes, soda or double bacon cheeseburgers. It's the simple potato, according to Harvard University researchers.

Daily consumption of an extra serving of spuds — French fries, crispy chips, mashed with butter and garlic, or simply boiled or baked — was found to cause more weight gain than downing an additional 12-ounce can of a sugary drink or taking an extra helping of red or processed meats.

Altogether, after tracking the good and bad diet and lifestyle choices of more than 120,000 health professionals from around the country for at least 12 years, the research team calculated that participants gained an average of 0.8 of a pound a year, close to the U.S. average, according to a report published in Thursday's edition of the New England Journal of Medicine.

It may not sound like much, but as the years go by "it becomes like compounded interest," adding up to 16 pounds over 20 years, said Dr. Jeffrey Schwimmer, director of the weight and wellness program at Rady Children's Hospital in San Diego, who wasn't involved in the study.

Potatoes have a long pedigree in the human diet. They were once hailed as history's most important vegetable, and the Incas — whose ancestors are credited with domesticating spuds in South America — worshiped a potato god.

They are still certified as a "heart healthy" food by the American Heart Assn. And the United Nations declared 2008 the International Year of the Potato, praising the tuber for being a good source of vitamin C, several B vitamins, and minerals including iron, potassium, phosphorus and magnesium.

But when the team from Harvard Medical School and the Harvard School of Public Health in Boston examined the potato's role in the modern diet, they found that people who ate an extra serving of French fries every day gained an average of 3.4 pounds over a four-year period. On top of that, those who munched on an extra serving of potato chips daily gained an average of 1.7 pounds every four years. Overall, an extra serving of potatoes prepared in any non-chip form was found to contribute an average of 1.3 pounds to total weight over four years.

The typical American consumes 117 pounds of potatoes each year, including 41 pounds in the form of previously frozen French fries, according to data from the U.S. Department of Agriculture. "Fresh" spuds account for only 28% of the total, the USDA said.

The problem, said study coauthor Dr. Walter Willett, chairman of the nutrition department at the Harvard School of Public Health, is that "we don't eat potatoes raw, so it's easier [for the body] to transform the starch to glucose."

Since spuds prompt a quick increase in blood sugar levels, they cause the pancreas to go into overdrive trying to bring levels back down to normal. As blood sugar spirals down, people usually experience hunger, which leads to snacking. Over many years, this cycle can result in drastic weight gain and a fatigued pancreas, possibly contributing to the development of Type 2 diabetes.

Making matters worse, potatoes pack a lot of calories into a relatively small package, said Dr. Dariush Mozaffarian, the study's lead author. A large baked potato — without any fixings — will set you back about 278 calories, and a serving of French fries contains between 500 and 600 calories. That makes the 140 calories in a 12-ounce can of Coca-Cola or the 150 calories in a Pepsi look puny.

But Willett said sugary beverages were hazardous to the waistline because so many people drink so many of them.

Frank Muir, president of the Idaho Potato Commission, said that if the researchers wanted to figure out what was behind the obesity crisis, they should have examined "onion rings, deep-fried pickles or any other food that is fried." Potatoes "stand up very well in terms of nutritional value per dollar input into the soil," he said, and they are "one of the most nutritional foods you can eat."

The researchers did find other culprits. For each additional sugary soft drink consumed per day, participants in the study gained an average of 1 pound over four years. Extra servings of red meats and processed meats did only slightly less damage.

Consuming an extra alcoholic drink translated into close to half a pound more on the scale every four years. Even 100% fruit juice took some blame — drinking an additional glass each day was tied with nearly a third of a pound in weight gain over the same period.

Some foods were linked to weight loss. For instance, eating an additional daily serving of fruit was associated with half a pound of weight loss over four years, and an extra daily serving of nuts was slightly better. An extra helping of vegetables each day added up to nearly one-quarter of a pound of weight loss every four years.

People who ate these foods regularly may have been less likely to consume higher calorie goodies, thus decreasing their total caloric intake, the researchers said.

Behavior mattered too. Every extra hour spent watching television each day correlated with half a pound of weight gain over four years. Conversely, increasing one's level of daily physical activity was linked with almost 2 pounds of weight loss over four years, though there was no link between absolute exercise levels and weight.

Sleeping too little or too much was also associated with weight gain. And compared with people who never smoked, onetime smokers who quit gained about a pound each year. In contrast, those who continued smoking were less likely to gain weight, which could be related to nicotine's suppressive effects on appetite.

The only finding the study authors said was surprising was that people tended to lose nearly a pound every four years if they ate an extra daily serving of yogurt. Though they are unclear about why this occurs, they posit that changes in gut bacteria may be responsible.

I was diagnosed as a severe diabetic about three years ago out of the blue. At 6'3" I am a relatively big guy but not obese and I have never been big on sweets. My dad is diabetic but at 90 has controlled his diabetes with diet and pills. Thankfully, my doctor sent me to diabetic school.

What an education! I was taught medically how dangerous diabetes really is and nutritionally they taught me how to eat as a diabetic. Everything has a carbohydrate value and you must eat accordingly. What has this all got to do with the potatoe? BIG CARBOHYDRATE value! For example: My allotment at my size is 4 to 5 portions of carbohydrates per meal. A small order of fries - 3 portions of carbohydrates! What that equates to if you are not diabetic is weight gain.

Good stuff Joe. It relates. Today I live with diabetes but through diet and only the introductory dosage in a pill form my diabetes is controlled. Watch out for the potatoe though.

I'm a potato lover too, but have to watch my carbohydrate intake. If I eat a big helping of steak fries and check my glucose it does jump up quite a few points.
