Eating Better May Stop Metabolic Syndrome

Wednesday, August 18th, 2010

Obesity, high blood pressure, and high cholesterol are all risk factors for cardiovascular disease; this combination of disorders is referred to as metabolic syndrome. And lack of exercise and poor diet increases your likelihood of developing any of these conditions.

But writing in the journal Diabetes Care, researchers say healthy eating can reverse metabolic syndrome.

For the study, scientists followed 339 people with metabolic syndrome for five years, finding participants who followed the nutritional guidelines of the Alternative Healthy Eating Index (AHEI), were nearly twice as likely to have reversed their metabolic syndrome.

Developed by the Harvard School of Public Health in 2002, the AHEI diet recommends eating whole grains over refined grains, white meat instead of red meat, and a lot of fruits, vegetables, nuts, and soy.

Data also showed individuals with the largest waist circumferences – more than 40 inches for men and more than 35 inches for women – who adhered to the healthiest diet were three times more likely to recover from metabolic syndrome.

So the researchers encourage people to improve the quality of their diets by adding more fruits, vegetables, and whole grains.

According to the World Health Organization, over 1 billion adults are overweight worldwide, with at least 300 million of them are obese.

Eating Less Red Meat Helps Your Heart

Tuesday, August 17th, 2010

Red meat doesn’t have a good reputation when it comes to heart health. Foods like beef and steak are high in cholesterol, a known risk factor for cardiovascular disease.

So a new study found reducing your red meat intake even a little bit helps lower your risk of high cholesterol and heart disease.

Writing in the journal Circulation, researchers say if you eat red meat more than once a day you’ll help your heart by swapping out one serving of meat with a less fattening food, like nuts or fish.

In the study, women who eat two servings of red meat each day have a 30% higher risk of cardiovascular disease compared to women who eat roughly three to four servings per week.

The researchers call it a “pretty dramatic increase,” highlighting the benefit of moderation and not overeating red meat.

Other findings show women eating one serving of beef each day raised their risk of heart disease by 8%, compared to who women rarely or never eat red meat. Other foods heightened risk more severely. Eating hotdogs once or twice a month raised risk 35%, bacon 41%, and hotdogs 42%.

Red meat has also been linked to a variety of cancers, such as prostate cancer, bladder cancer, colon cancer, stomach cancer, and breast cancer.

Heart Troubles Less Likely in Fish Eaters

Tuesday, July 27th, 2010

Fish is a staple in many parts of the world, especially countries near the ocean, like Japan, the Philippines, and Mediterranean nations, such as Italy and Greece.

Nutritionally fish is an excellent source of omega-3 fatty acids; a “good fat” linked to reduced risk of cardiovascular disease.

And now, published in the Journal of the American Dietetic Association, a new study involving 3,500 Korean adults, ages 40 to 69, found that men who consumed one serving of fish each day had a 57% lower risk of developing metabolic syndrome over the next three years.

Metabolic syndrome is a collection of conditions contributing to heart disease; including diabetes, high blood pressure, and high cholesterol.

In the study, men consuming the most fish had the lowest risk of metabolic syndrome, compared to men eating less fish. Researchers point to omega-3 intake as being responsible for the reduction of risk, but they aren’t certain what the daily recommendation for omega-3 fatty acids should be.

But a major concern about fish and seafood is mercury contamination. Smaller fish consume pollutants that work their way up the food chain as they’re eaten by larger predatory fish like swordfish and red snapper; which people often consume at restaurants.

So by the time humans consume these varieties of fish they’ve already accumulated high levels of mercury, even canned tuna is one of the most contaminated fish available.

Eggs Don’t Raise Diabetes Risk

Monday, June 21st, 2010

Eggs are a pariah. They’re very high in cholesterol, and we all know that high cholesterol is a risk factor for cardiovascular disease.

But eggs are a good source protein, omega-3 fatty acids, calcium, and vitamin D; but they’re cholesterol content usually keeps them off people’s menus, especially individuals who have already suffered a heart attack.

And for many years it was believed consuming eggs also raised the risk of type-2 diabetes, but now a new study challenges that claim.

Writing in the American Journal of Clinical Nutrition, researchers determined eating eggs everyday was not associated with the development of type-2 diabetes.

For the study, scientists followed 3,898 men and women, at least 65 years old, already participating in a heart-related study, and at the end of 11 years only 313 people had type-2 diabetes.

So the researchers say consuming eggs occasionally or even daily did not contribute to the development of type-2 diabetes. Type-2 diabetes is largely a lifestyle disease; major risk factors are poor diet and lack of exercise.

Humans consume many different kinds of eggs, not just chicken eggs. In China, people eat salted duck eggs. The eggs are salted by soaking them in brine.

And in dive bars across the United States you can find a jar of pickled eggs, next to the pig knuckles and pretezels.

Chocolate May Lower Cholesterol

Wednesday, June 2nd, 2010

Just say the word chocolate and most people start salivating like a grizzly Rottweiler staring down a mailman.

And not only is chocolate a god among confectionaries, but it’s also been linked to a variety of health benefits; such as protecting against heart disease.

Chocolate has earned that reputation because of its high concentration of antioxidants, which have been shown to reduce oxidation; a risk factor for cardiovascular disease.

And now, published in the American Journal of Clinical Nutrition, researchers say consuming small amounts of chocolate – sorry, only 6 grams – may lower cholesterol levels in some people.

Individuals who already had heart disease showed a reduction in LDL, or “bad,” cholesterol when eating modest amounts of chocolate – so you shouldn’t devour an entire bag of Hershey’s Assorted Miniatures.

And chocolate’s effect on reducing cholesterol was attributed to polyphenols – surprise-surprise, an antioxidant. A 1.25 ounce bar of chocolate contains roughly 300 milligrams of polyphenols.

But if you don’t like chocolate, or are more of a vanilla person – or shudder the thought, a strawberry person – polyphenols can also be found in vegetables and wine.

Nuts Shown to Lower Cholesterol

Monday, May 17th, 2010

Arguably, a bowl of nuts goes best with a pint of beer in a dimly lit bar. But nuts – despite their “nuts are fattening” stigma – are incredibly healthy foods.

Nuts contain fiber, antioxidants, healthy fats, and many vitamins and minerals, like vitamin E, copper, and potassium.

So it’s no surprise that eating nuts has been found to lower LDL, or “bad,” cholesterol.

Writing in the Archives of Internal Medicine, researchers discovered individuals with high cholesterol, healthy bodyweights, or people already eating a good diet experienced lower cholesterol when consuming nuts.

Unlike meat – which everyone knows is full of bad fats – nuts are a source of HDL cholesterol, i.e. “good” cholesterol.

For the study, scientists examined the effects of eating nuts on men and women, finding that consuming an average of 2.4 ounces of nuts each day lowered participants’ cholesterol levels by 5%, reduced LDL cholesterol 7%, and improved the ratio between LDL and HDL.

Researchers note study participants with high cholesterol received the most benefit from eating more nuts each day and nuts yielded a “dose response” – meaning the more nuts the people ate, the greater the benefit.

Oh, and a fun fact! Even though we call them peanuts, they’re not really a nut at all. Peanuts are a legume – i.e. a bean – so you’ve been eating bean butter the whole time. Doesn’t sound nearly as appetizing, does it?

One-Fifth of American Teens Have Unhealthy Cholesterol

Thursday, January 28th, 2010

TEENNot exactly a good start for the future of a country.

The Centers for Disease Control and Prevention reports one in five American teenagers have high cholesterol levels.

High cholesterol is a known risk factor for heart disease.

Studying data from a national health survey, the CDC found 20.3% of young people, ages 12 to 19, had unhealthy cholesterol levels.

Heavier teens were more likely to have high cholesterol and boys were found to be at higher risk than girls.

Researchers say unhealthy cholesterol often begins in childhood and adolescence, so it’s important that doctors identify it early and recommend lifestyle interventions.

Too Much TV Can Raise Death Risk

Wednesday, January 13th, 2010

TVIt’s hard to resist back-to-back episodes of Sanford and Son, but too many marathons of TV watching may shorten your life, especially if you endlessly channel surf every day.

Published in the journal Circulation, scientists found each hour spent sitting in front of the television raised a person’s risk of dying prematurely from heart disease.

For the study, experts tracked the lifestyle habits of 8,800 adults; such as smoking, diet, exercise, waist measurement, and high blood pressure and high cholesterol.

Data showed every hour spent in front of the television was associated with an 11% higher risk of dying from all causes; 9% higher risk of cancer death; and an 18% increased risk of death due to cardiovascular disease.

And people watching more than four hours of TV each day had a 46% higher risk of death from all causes and an 80% higher risk of heart disease related death.

So if you take in a little too much boob-tube every day, you’ll be doing the Fred Sanford chest grab for real.

High Cholesterol Adds to Heart Failure Risk

Thursday, November 26th, 2009

HRTIt sounds obvious. Eating fatty foods, raises cholesterol, clogs arteries, and then WHAM you have a heart attack.

Shouldn’t be a surprise when it happens, but for millions of people it’s a real shocker.

So, a new study aims to clarify the risk, in case you didn’t know.

Published in the journal Circulation, a new study found people with high non-HDL cholesterol, which includes LDL, or bad, cholesterol had 13% higher risk of heart attack.

But on the other hand, individuals with high HDL, or good, cholesterol had a 25% lower risk of heart attack.

So researchers suggest cholesterol altering therapies for both HDL and LDL cholesterol should be considered for heart patients.

Foods that lower bad cholesterol, because they don’t have any, are fruits and vegetables, and healthy fats, like omega 3’s, contained in things like walnuts, have been shown to be cardio-protective.
