Low-Carb Diets and Heart Disease

Saturday, August 21st, 2010

by Jeannine Stein

The fascination with low-carb versus low-fat diet continues; the latest news comes from a study in the Annals of Internal Medicine released Monday that found that people on both diets lost about the same amount of weight over two years. However, the low-carb group had an edge in raising HDL (good) cholesterol and lowering diastolic blood pressure

The study looked at 153 people who were randomly assigned to a low-carb diet, and 154 to a low-fat diet. The low-carb group limited carbohydrate intake to 20 grams per day for the first 12 weeks, then gradually increased fruits, vegetables, whole grains and dairy foods until they reached a desired weight. The low-fat group kept daily calories to 1,200 to 1,500, and fat to 30% of their diet.  (more…)

The heart disease trifecta

Sunday, May 2nd, 2010

Nearly half of all adult Americans have high cholesterol, high blood pressure or diabetes, all of which boost the risk of cardiovascular disease, the CDC says. One in eight has two or more.

April 26, 2010|By Thomas H. Maugh II, Los Angeles Times

Nearly half of all adult Americans have high cholesterol, high blood pressure or diabetes, all conditions that increase the risk of cardiovascular disease, researchers from the national Centers for Disease Control and Prevention said Monday.

One in eight Americans has at least two of the conditions and one in 33 has all three, sharply increasing their risk. Of those with at least one condition, 15% have not been diagnosed, according to the report released online.

“The number that really surprises me is the penetration of these conditions into the U.S. population,” said Dr. Clyde Yancy of Baylor University Medical Center, president of the American Heart Assn. “When that number is nearly 50%, that’s a huge wake-up call.” It means there are a large number of people “who think they are healthy…but are working under a terrible misconception.” (more…)

Too much sugar increases heart disease risk

High cholesterol a dangerous side effect to extra sweeteners, study says

updated 7:34 p.m. ET, Tues., April 20, 2010

CHICAGO – Eating a lot of sugar not only makes you fat. It may also increase a person’s risk for heart disease, U.S. researchers said.

They said people who ate more added sugar were more likely to have higher risk factors for heart disease, such as higher triglycerides and lower levels of protective high-density lipoprotein or HDL cholesterol.

“Just like eating a high-fat diet can increase your levels of triglycerides and high cholesterol, eating sugar can also affect those same lipids,” Dr. Miriam Vos of Emory School of Medicine, who worked on the study published in the Journal of the American Medical Association, said in a statement.

The study adds to mounting pressure on U.S. food companies to make their foods healthier as newly passed U.S. health reform legislation shifts the nation’s focus on ways to prevent, rather than simply treat disease.

A report by the influential Institute of Medicine released on Tuesday recommended that the U.S. Food and Drug Administration start to regulate sodium intake in foods. (more…)

Happiness wards off heart disease, study suggests

Happiness wards off heart disease, study suggests

Happy couple

Happiness has been linked to improve health before

Being happy and staying positive may help ward off heart disease, a study suggests.

US researchers monitored the health of 1,700 people over 10 years, finding the most anxious and depressed were at the highest risk of the disease.

They could not categorically prove happiness was protective, but said people should try to enjoy themselves.

But experts suggested the findings may be of limited use as an individual’s approach to life was often ingrained.

At the start of the study, which was published in the European Heart Journal, participants were assessed for emotions ranging from hostility and anxiousness to joy, enthusiasm and contentment.

They were given a rating on a five-point scale to score their level of positive emotions.

By the end of the analysis, some 145 had developed heart disease – fewer than one in 10.

But for each rise in the happiness scale there was a 22% lower risk of developing heart disease.

Essentially spending a few minutes each day truly relaxed and enjoying yourself is certainly good for your mental health and may improve your physical health as well
Dr Karina Davidson

The team believes happier people may have better sleeping patterns, be less liable to suffer stress and be more able to move on from upsetting experiences – all of which can put physical strain on the body.

Lead researcher Dr Karina Davidson admitted more research was needed into the link, but said she would still recommend that people try to develop a more positive outlook.

She said all too often people just waited for their “two weeks of vacation to have fun” when instead they should seek enjoyment each day.

“If you enjoy reading novels, but never get around to it, commit to getting 15 minutes or so of reading in.

“If walking or listening to music improves you mood, get those activities in your schedule.

“Essentially spending a few minutes each day truly relaxed and enjoying yourself is certainly good for your mental health and may improve your physical health as well.”

It is not the first study to suggest there is a link between happiness and health.

But Ellen Mason, of the British Heart Foundation, suggested such an association may be of limited value anyway.

“We know that improving your mood isn’t always easy – so we don’t know if it’s possible to change our natural levels of positivity.”

Cardiologist Iain Simpson, of the British Cardiovascular Society, added: “Things like reducing cholesterol and diabetes are more important when it comes to reducing heart disease.

“But at the end of the day it heart disease is still the biggest killer in the UK so anything you can do to help should not be ignored.”

Study Supports Connection Between BPA and Heart Disease

By Rachel Ehrenberg, Science

A previously reported link between exposure to the plastics chemical bisphenol A and heart disease stands, reports a new study published online January 12 in PLoS ONE.

 

Added to previous work, the finding provides a third prong of evidence implicating the chemical in cardiovascular and metabolic problems, notes Richard Stahlhut of the Center for Reproductive Epidemiology at the University of Rochester in New York. “It’s becoming a coherent picture that really does fit together,” says Stahlhut, who was not involved in the research. “If these all connect, we really do have a problem.”

Researchers analyzed data from the 2005–2006 National Health and Nutrition Examination Survey, or NHANES, conducted by the U.S. Centers for Disease Control and Prevention. NHANES uses physical examinations, clinical and lab tests, and personal interviews to get a snapshot of the health and nutritional status of the U.S. population. The new analysis of 2005–2006 data reveals an association between concentrations of bisphenol A in urine and risk of cardiovascular disease, a link also detected in the 2003–2004 NHANES data.

According to researchers, previous studies have shown that paediatric cancer survivors are up to 10 times more likely to have heart disease, compared to those not affected by this type of cancer.

As part of this study, the researchers set out to determine whether risk factors for heart disease, such as obesity and diabetes, were present at higher rates in cancer survivors.

“If the risk factors could be recognised and treated early it is hoped some of the long-term cardiac side effects could be averted,” said lead author, Dr Lillian Meacham of Emory University in Atlanta.

She analysed data relating to 8,599 cancer survivors and 2,936 of their siblings and found that cancer survivors were nearly twice as likely to take medication for high blood pressure as their siblings. They were also 60 percent more likely to take cholesterol medication and 70 percent more likely to have diabetes.

Dr Meacham suggested that radiation treatment for cancer may play a role in the development of risk factors for heart disease.

She found that those who had undergone total body irradiation were at a 5.5-fold increased risk of having a number of cardiovascular risk factors. Those who underwent chest and abdomen radiation were at a 2.2-fold increased risk.

“We are not yet sure why this is, but the association is definitely there,” she said.

Meacham also noted that these cardiovascular risk factors were manifesting at around the age of 32, which is much younger than a non-cancer survivor would show signs of such risk factors.

“Some have suggested that when you are a cancer survivor there are parts of you that wear out early, so we need to be vigilant about our follow-up of these patients in order to find these late effects early and intervene,” she said.

The study has been published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Overweight Kids Show Early Signs of Heart Disease

Thursday, September 24th, 2009

Friday, April 17, 2009NEW YORK – Children who are overweight but otherwise “healthy” may have stiff arteries, putting them at increased risk for heart disease, a study shows.

As people age, the arteries normally lose some of their elasticity, making them less responsive to changes in blood flow. Stiff arteries put increased strain on the heart, often leading to high blood pressure. (more…)

NEW YORK – Children who are overweight but otherwise “healthy” may have stiff arteries, putting them at increased risk for heart disease, a study shows.

As people age, the arteries normally lose some of their elasticity, making them less responsive to changes in blood flow. Stiff arteries put increased strain on the heart, often leading to high blood pressure.

The rising prevalence of childhood obesity is associated with the premature development of cardiovascular risk factors such as high cholesterol and high blood pressure, the study team notes. In addition, there is emerging evidence that such obesity-related conditions predict the development of heart disease in adulthood. (more…)

Questions and Answers About Chelation Therapy

Saturday, July 26th, 2008

For more than30 years, people with fatty buildups of plaque in their arteries (atherosclerosis) may have heard about a “miracle cure” called chelation (pronounced “ke-LA’shun”) therapy. But you may not know that the American Heart Association and other medical and scientific groups have spoken out against this treatment.

This answers the most frequently asked questions about chelation therapy. It also gives the American Heart Association’s position on this procedure, as well as those of other highly regarded scientific organizations. (more…)
