Sugar and salt are damaging the health of Americans by raising blood pressure and cholesterol -- and regulation may be the only way to help, researchers agree.
Two reports published on Tuesday take aim at the much-loved ingredients and add to a growing body of scientific opinion that Americans won't be able to eat more healthily without help from the food industry.
Americans have been eating more and more sugar and salt in recent decades and most of it is not sprinkled on food. It is in the burgers, sodas and processed foods that are hastily gobbled by adults and children alike, the reports show.
Education efforts to help Americans cut down on salt have not worked and the U.S. Food and Drug Administration should start regulating the industry to help remove it from food, a panel at the Institute of Medicine said.
Regulators and the food industry agree that Americans cannot give up salt cold-turkey and will have to be gradually weaned off it. Sodium adds flavor and texture to food to make it palatable and can extend its shelf life.
In another study Dr. Miriam Vos of Emory School of Medicine in Georgia and colleagues found that the more sugar people ate, the worse their cholesterol levels.
"Just like eating a high-fat diet can increase your levels of triglycerides and high cholesterol, eating sugar can also affect those same lipids," Vos said in a statement.
Studies have shown Americans are eating and drinking far more sugar than in years past. The use of processed sugar products like high fructose corn syrup can be linked directly to diabetes rates.
The food and restaurant industry has been lobbying for self-regulation, arguing that Americans need to control their own eating habits. But the science shows it is difficult to eat a typical American diet without consuming too much salt and sugar.
MANDATORY POLICY
The trend points in one direction: more regulation of food.
While a move to limit sugar is not imminent, Iowa Senator Tom Harkin and Representative Rosa DeLauro of Connecticut said they would push the FDA to crack down on salt, which clearly contributes to an epidemic of high blood pressure.
"What we're all hoping is this is going to be federal policy so it becomes mandatory. I think slow and steady is the right way to go," Dr. Alice Lichtenstein of the American Heart Association said in a telephone interview.
"If across the board reductions in sodium in our food supply become law, then I think a gradual, stepwise approach is probably best in the long run to ensure that it actually happens and there is acceptance from the people."
New York City, which has banned smoking and artificial trans-fats in restaurants, has pledged to coordinate a nationwide effort to reduce salt in restaurant and packaged foods by 25 percent over five years.
As for sugar, California state Senator Dean Florez introduced legislation in February to tax sodas and other sugar-sweetened drinks and use the proceeds to bankroll programs to fight childhood obesity.
California has also imposed menu-labeling rules and banned trans-fats in restaurants and on soda sales in public schools.
The American Beverage Association, whose members include Coca-Cola (KO.N) and Kraft Foods (KFT.N) have strongly, and successfully, opposed efforts to tax soda.
However the food industry has been more amenable to offering lower-salt foods and the FDA suggests it will work with manufacturers to make the transition painless.
The Obama Administration and Congress have shown strong appetites for regulating the food and restaurant industry. Newhealthcare reform legislation requires large chain restaurants to give calorie counts on menus.

Obesity Takes Years Off Your Life
It's similar to smoking when it comes to effect on longevity, researchers note
TUESDAY, March 17 (HealthDay News) -- Being obese can shorten your life, a new study shows.
"Moderate obesity typically shortens life span by about three years," said researcher Gary Whitlock, from the Clinical Trial Service Unit at the University of Oxford in the United Kingdom. "By moderate obesity, I mean weighing about a third more than is ideal, which for most people would mean being about 50 or 60 pounds overweight."
More than one in three middle-aged Americans are now in this category, Whitlock said. "By contrast, weighing twice your ideal weight -- say, an extra 150 pounds -- shortens life span by about 10 years," he added.
This obesity level is still not common, but it equals the known 10-year reduction in life span caused by smoking. "So, smoking is about as dangerous as being severely obese, and about three times as dangerous as being moderately obese," he said.
The report is published in the March 18 online edition of The Lancet.
For the study, Whitlock and other members of the Prospective Studies Collaboration collected data on 894,576 men and women who participated in 57 studies. The people in these studies came primarily from western Europe and North America. Their average body-mass index (BMI) was 25.
BMI is a calculation that expresses a relationship between height and weight. People are considered underweight if their BMI is less than 18.5, normal weight when the BMI is between 18.5 and 24.9, overweight when BMI is between 25 and 29.9, and obese when BMI is 30 or more, according to the U.S. National Heart, Lung, and Blood Institute.
The researchers found that men and women whose BMI was between 22.5 and 25 lived the longest. For a person 5 feet 7 inches tall, his or her optimum weight would be about 154 pounds, they noted.
For those with a BMI over 25, every 10 to 12 pound increase translated to about a 30 percent increased risk of dying. In addition, there was a 40 percent increase in the risk for heart disease, stroke and other vascular disease, a 60 percent to 120 percent increased risk of diabetes, liver disease or kidney disease, a 10 percent increased risk of cancer, and a 20 percent increased risk for lung disease, the researchers reported.
"Obesity causes kidney disease, liver disease and several types of cancer, but the most common way it kills is by causing stroke and, most importantly, heart disease. Obesity causes heart disease by pushing up blood pressure, by interfering with blood cholesterol levels, and by bringing on diabetes," Whitlock said.
People who are moderately obese with a BMI in the 30 to 35 range reduced their life span by two and four years. For those who are severely obese with BMIs between 40 and 45, their life span was reduced by eight to 10 years. That's comparable to the effects of smoking, Whitlock said.
In fact, people whose weight was below normal also died earlier, due mainly to smoking-related diseases, the researchers noted.
"If you are obese and smoke, then, above all else, quit smoking," Whitlock said. "If you are obese and don't smoke, then don't start, and do what you can to avoid further weight gain. By avoiding further weight gain, you may well live a few years longer than you otherwise would do. By quitting smoking, a smoker can expect to gain several extra years of life -- about as many as a severely obese person might gain by shedding half of his or her body weight."
Dr. David L. Katz, director of the Prevention Research Center at Yale University School of Medicine, said this study confirms that the obesity epidemic is "the clear and present danger many of us knew it to be."
The association between BMI and mortality has been challenged in the scientific community, due in part to uncertainty about weight estimates and debate about measurement methods. "Here we have an emphatic reaffirmation of the fundamental issue: Overweight and obesity take years from life," Katz said.
"We know that, in many ways, BMI is a crude measure of the health risks associated with obesity, since not all excess body fat is created equal," he said. "Weight gained around the middle tends to be most dangerous, so for those subject to this pattern, risks may indeed be higher than this study suggests. For those with lower body weight gain, risks may be lower."
A study published in the Nov. 13 issue of the New England Journal of Medicine also found that where weight is centered is a risk factor. Men with the largest waist circumference had more than double the risk of death, and women with the largest waist circumference increased their risk of death by 78 percent.

There's buzz about blueberries, for instance, for their memory-boosting potential. But berries of all hues are antioxidant-rich, reports Navindra P. Seeram, Ph.D., assistant professor at the University of Rhode Island College of Pharmacy in Kingston. That means they combat free radicals, molecules that can cause widespread cell damage and are linked to chronic inflammation. Unlike the inflammation that occurs when you sprain an ankle or strain a muscle, the type that contributes to aging is persistent, and thought to be at the root of most chronic diseases, from cancer, heart disease, and diabetes to Alzheimer's, arthritis, and osteoporosis. Berries' beauty bonus: They're chock-full of vitamin C, another potent antioxidant that may help keep your complexion looking smooth by fighting those pesky (skin-damaging) free radicals.
To keep your vision sharp, set your sights on spinach and other dark leafy greens. These veggies are prime sources of lutein and zeaxanthin, plant pigments that protect your eyes from the harmful effects of ultraviolet light. Leafy greens are also rich in vitamin K, a nutrient that plays a role in reducing bone loss and preventing fractures.
How to Pick the Perfect Produce
2. Protein (Try these One-Dish Dinners)
This key dietary component becomes even more critical starting in the 40s, when muscle mass begins to decline by up to 1 percent a year. That drop slows metabolism, which makes the pounds pile on more easily. The double whammy consequence: Added weight puts your health at risk, and down the road, diminished muscle mass can throw off your balance (upping chances of a fall), sap your strength, and even threaten your ability to recover from an illness or accident.
To hang on to your metabolism-boosting muscle — and keep you feeling full after meals (another protein plus) — experts recommend eating plenty of skinless chicken and turkey breast, lean beef and pork, eggs, beans, and seafood. And don't forget protein-rich dairy: Minerals (primarily calcium, phosphorus, and potassium) in fat-free milk and yogurt as well as low-fat cheeses help to keep blood pressure healthy, pudge in check, and bones strong. News flash: Calcium can't build bone if you're not getting enough protein, and current recommendations — about five ounces a day for a 145-pound woman — are too low, says Robert P. Heaney, M.D., professor of medicine at Creighton University in Omaha. Our Anti-Aging Meal Plan provides about 11 ounces of protein daily.
Another reason to spoon up some yogurt: Eating at least 1/4 cup every day led to a 60 percent lower risk of gum disease and a 50 percent lower risk of tooth loss in a Japanese study published in the Journal of Periodontology. The effect is thought to be linked to the probiotics in yogurt, but not in most other dairy.

3. Omega-3-Rich Fish
Fatty acids in seafood help quench the flames of chronic inflammation. In addition, "there's very good new data suggesting that omega-3 fats from fish act on an area of the brain that leads to improved mood and attitude among healthy people," says Artemis P. Simopoulos, M.D., author of The Omega Diet. These improvements in outlook lead to feeling healthier and more vigorous, she explains. The omega-3s in fatty fish like salmon and tuna have the most potent anti-inflammatory effects. But it's smart to consume omega-3s from plant sources, like walnuts and flaxseed, too — especially if you're not fond of fish.
4. Whole Grains
A 2008 review of these diet-friendly foods — which include whole wheat, oats, and brown rice, and the bread, cereal, and other edibles made from them — concluded that a meal plan loaded with whole grains helps you stay slim, thanks, in part, to fiber's role in appetite control. Their low rankings on the glycemic index (a system that rates the effect of different carbohydrates on blood sugar levels) may also play a role.
A raft of research has also shown that whole grains offer protection against diabetes, heart disease, stroke, colon cancer, high blood pressure, and gum disease. These benefits are tied to the array of vitamins, minerals, plant chemicals, and again, fiber that work together to promote health. (That's why refined grains, which filter out these nutrients during manufacturing, and add some back later in the process, don't offer the same advantages.)
5. Exercise
It's an anti-aging bonanza: Being active maintains muscle mass, boosts metabolism, and keeps your heart and lungs primed, among other benefits. Now, a recent study has found that running, in particular, promotes a long, independent life. Researchers at Stanford University School of Medicine followed a group of runners and non-runners for 21 years and found that elderly runners put off age-related disabilities for16 years beyond their non-running counterparts. Runners also lived longer: 19 years into the study, only 15 percent of them had died compared with 34 percent of the non-runners. And the active ones were less likely to die from heart disease, stroke, cancer, and neurological conditions. While this study examined running, 30 minutes of more moderate aerobic activity, five days a week, will keep you healthy, according to recently released guidelines from the American Heart Association and American College of Sports Medicine. What should also be on your fitness agenda: strength training twice a week to maintain muscle and keep your metabolism humming.

6. Red Wine and Other Drinks
What other diet recommends red wine? Ours does because the ruby beverage's resveratrol is a potent antioxidant, inflammation damper, and artery protector. Plus, animal research suggests that high amounts of resveratrol may counteract cell death in the heart and brain, which could mean this compound has even greater potential to prolong your life. Limit yourself to one five-ounce glass a day; more could be harmful.
If you're not a wine drinker, no worries: Put on the coffeemaker or the kettle instead. Coffee appears to lower the risk of type 2 diabetes and Parkinson's disease, and evidence suggests that java drinkers have a lower chance of dying from heart disease. Some of the benefit may come from caffeine, but coffee also contains chlorogenic acids, antioxidants that might also play a protective role. Drinking tea may lower your risk of heart attacks, strengthen your immune system, protect tooth enamel, and help fight memory loss associated with aging. Choose green, black, white, or oolong — their leaves all come from the camellia sinensis, or tea plant. And their polyphenols (antioxidants), fluoride, and caffeine — which are thought to contribute to these health benefits — are largely missing from herbal brews.
Two Secret Age-Defying Treats
They seem like diet no-no's because of their calorie load, but dark chocolate and a handful (not a canful) of nuts have longevity and weight-loss benefits.
This just in: Nuts give you a surprising diet edge. A recent study found that despite being a high-fat, high-cal food, they don't promote weight gain. The reason: People find nuts filling and after eating them, offset some of the calories by eating less later on. Best of all, up to 20 percent of the calories in nuts don't get absorbed.
Craving something sweet? Dip into dark chocolate. The latest evidence suggests that cocoa flavanols (more predominant in dark chocolate than milky versions) may lower inflammation, keep blood pressure in check, prevent platelets from clotting (which could, in turn, prevent strokes and heart attacks), and boost brain power.
