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.

Depression and Cholesterol Link Varies Between Gender

Monday, August 2nd, 2010

Cholesterol is an important component of mammalian cell membranes, but high levels of LDL, or “bad,” cholesterol have long been associated with increased risk of heart disease and high blood pressure.

Food sources of LDL cholesterol are eggs, steak, bacon, butter, and other animal foods. Plant foods do not contain LDL cholesterol.

Depression is another condition linked to cholesterol levels. Some experts contend low cholesterol may be associated with an elevated risk of depression.

And now a new study, published in the journal Biological Psychiatry, found depression in women was linked to low levels of HDL, or “good,” cholesterol, which also raises people’s risk of cardiovascular disease.

Foods that increase HDL cholesterol include water soluble fibers found in fruits and vegetables, like beans, apples, grapes, and citrus fruits, and whole grains, such as oats, oat brain, and brown rice. Omega-3 fatty acids contained in avocados, flaxseed oil, and fish, like salmon and mackerel also raise HDL cholesterol.

The research, which involved elderly people, ages 65 and older, also discovered men were more likely to suffer depression if they had low levels of LDL cholesterol.

So the scientists recommend cholesterol levels be closely monitored among the elderly in order to prevent depression.

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.

“Good” Cholesterol Helps Lower Cancer Risk

Wednesday, June 16th, 2010

There are  two kinds of cholesterol: HDL, or “good” cholesterol, and LDL, or “bad,” cholesterol.

It’s the classic story of good versus evil; HDL protects your body, while LDL increases your risk of cardiovascular disease, especially heart attack, stroke, and high blood pressure.

You can raise HDL – short for High-density lipoprotein – by eating foods like oats, fruit, beans, lentils, brown, and omega- 3 fatty acids found in fish and olive oil.

And in addition to lowering risk of heart disease, a new study claims HDL cholesterol may also reduce your risk of developing of cancer; such as pancreatic cancer.

Published in the Journal of the American College of Cardiology, researchers analyzed data from 24 clinical trials on 150,000 generally healthy people, revealing with a ten point increase in participants’ HDL cholesterol cancer risk dropped to a 36% decrease.

In general the scientists say people should keep their HDL cholesterol levels above 60mg/dl, and recommend maintaining a healthy lifestyle, with of plenty exercise and eating a good diet, to help achieve good HDL levels.

And to keep your LDL cholesterol – short for Low-density lipoprotein – low, avoid consuming a lot of animal foods, specifically red meat and bacon.

Mediterranean Diet Helps People with Heart Disease

Wednesday, June 9th, 2010

The Mediterranean diet has long been associated with better health, especially reducing the risk of cardiovascular disease.

But now, a new study suggests following the Mediterranean diet – which is rich in fruits, vegetables, wine, whole grains, beans, nuts, fish, and olive oil, and low in meat and dairy – may help your heart even if you already have heart disease.

Writing in the American Journal of Clinical Nutrition, experts found people who suffered a heart attack were 31% less likely to have another heart attack – or even chest pains – if they consumed a “Mediterranean-style” diet.

Results of the study had a dose effect. The more closely participants followed a Mediterranean diet the more the risk of another cardiac even decreased.

And specific foods had a very positive effect on heart attack risk. People eating nuts and vegetables daily or weekly had a 20% lower risk of having a heart attack two years after their initial hospitalization.

Nuts, despite their infamous high fat content, are known heart protectors. Consuming nuts, like walnuts and almonds, helps reduce LDL, or “bad,” cholesterol concentrations.

So the researchers recommend people incorporate elements of the Mediterranean diet into their eating habits to improve heart health.

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?

Sugar Lowers “Good” Cholesterol

Tuesday, April 27th, 2010

Put the Kool-Aid down! Eating sugar wreaks havoc on your body, especially your ticker.

Sugar rots your teeth and makes you fat, but experts say sugar also lowers HDL or “good” cholesterol and raises triglycerides; both risk factors for heart disease.

So this isn’t good news – at all!

Printed in the Journal of the American Medical Association, researchers found upwards of 16% of some people’s daily calories come from sugar.

For the study, 6,000 people were asked about their sugar consumption. Some of the participants ate as much as 46 teaspoons of added sugar each day.

How much of that added sugar is tied up in coffee I wonder? Another super food – sigh.

Green Tea May Reduce Depression After Breast Cancer

Wednesday, January 27th, 2010

GTGreen tea sounds like a lot of hocus pocus; having originated in China, it is subject to “ancient Chinese secret” clichés.

But drinking green tea has been linked to positive health effects, like lowering cholesterol and blood pressure.

And now, a new study published in the Journal of Clinical Oncology claims green tea may help ease depression, specifically in breast cancer survivors.

In addition to exercise, findings showed among the 1,216 participants—women treated for breast cancer—the 183 women who drank green tea had a 36% lower risk of depression.

Scientists point out that exercise and tea drinking were the only factors in the study that seemed to alter depression risk; not things like alcohol, smoking, and use of herbal supplements—which were also assessed.
