Sugar Sweetened Beverages Increase Risk Of Heart Disease

Sugar-Sweetened Beverages Linked to Increased Risk of Heart Disease in Men
Cola Drinks
Men who drank a sugar-sweetened beverage (12-ounces) a day had a 20 percent higher risk of heart disease compared to men who didn’t
drink any sugar-sweetened drinks, according to research published in Circulation, an American Heart Association journal.

“This study adds to the growing evidence that sugary beverages are detrimental to cardiovascular health,” said researchers from the department of nutrition and epidemiology in the Harvard School of Public Health in Boston, Mass. “Certainly, it provides strong justification for reducing sugary beverage consumption among patients, and more importantly, in the general population.”

Heart disease is the leading cause of death in the United States. The most crucial risk factors include obesity, smoking, physical inactivity, diabetes and poor diet.
Researchers, who studied 42,883 men in the Health Professionals Follow-Up Study, found that the increase persisted even after controlling for other risk factors, including smoking, physical inactivity, alcohol use and family history of heart disease. Less frequent consumption of the sweetened beverages such as twice weekly and twice monthly  did not increase risk.
Researchers also measured different lipids and proteins in the blood, which are indicators (biomarkers) for heart disease. These included the inflammation marker C-reactive protein (CRP), harmful lipids called triglycerides and good lipids called high-density lipoproteins (HDL). Compared to non-drinkers, those who consumed sugary beverages daily had higher triglyceride and CRP and lower HDL levels.
Artificially sweetened beverages were not linked to increased risk or biomarkers for heart disease in this particular study.
Beginning in January 1986 and every two years until December 2008, participants responded to questionnaires about diet and other health habits. They also provided a blood sample halfway through the survey. Follow-up was 22 years.
Participants were primarily Caucasian men 40-75 years old. All were employed in a health-related profession.
Health habits of the men in the study may differ from those of the general public, but findings in women from the 2009 Nurses’ Health Study were comparable.
The American Heart Association recommends no more than half of discretionary calories come from added sugars . For most American men, that’s no more than 150 calories per day and 100 for most American women. Discretionary calories are those left in your “energy allowance” after consuming the recommended types and amounts of foods to meet all daily nutrient requirements.
The Canadian Institutes of Health Research funded the analysis and the National Institutes of Health funded the Health Professionals Follow-Up Study.

Maintainin​g Normal Weight and Other Key Health Factors Affect Brain Function

Nutritious dietary intake and maintaining

healthy weight is good for your brain…

Eating a healthy diet and maintaining a normal weight helps protect your brain, according to a 10-year study of 6,401 British civil servants.

Participants in the study (initially ages 39-63) were less likely to have impaired cognitive function if they were not overweight or obese.

Those with multiple markers of “metabolic abnormality” were more likely to suffer impaired cognitive function; these markers included high cholesterol or triglycerides, high blood pressure, low HDL (good) cholesterol, high glucose levels or diabetes.

In followup mental testing at the 5 and 10-year points, those who were both obese and “metabolically abnormal” were significantly more likely to show a faster rate of cognitive decline.

Researchers speculated that vascular problems associated with unhealthy weight might affect brain function, along with specific fat-related secretions that impact the aging brain.

Good Cholestero​l Benefits From Soy: New Study

Study Supports Soy Cholesterol Benefits…

Despite past evidence suggesting that eating soy might only lower cholesterol in those whose bodies are able to convert it to an estrogen-like compound called equol, a new study shows soy might benefit a wider range of people.

Canadian researchers discovered that a diet high in soy isoflavones lowered  “bad” cholesterol ( LDL ) about equally in people who were considered equol producers and in those who were not. The equol producers, however, maintained their previous levels of “good” HDL cholesterol, while the non-producers’ HDL levels also dropped.

Nutrition researchers at the University of Toronto in Canada used three previous studies to test whether the ability to produce equol from soy products was linked to changes in cholesterol.

The researchers analyzed data on 85 people who participated in one of the three studies. In each of the studies the participants ate between 30 grams and 52 grams of soy foods including: tofu burgers or tofu hot dogs every day over four weeks.

Before they started eating the soy, both equol and non-equol producers had LDL cholesterol in the range that would be considered high according to the American Heart Association (AHA). Their HDL cholesterol was also considered low.

For LDL cholesterol, the AHA says a reading between 160 milligrams per deciliter (mg/dL) and 189 mg/dL is high, while HDL cholesterol below 60 mg/dL is considered low and not protective against heart disease.

After the study, the 33 equol producers’ HDL stayed about the same, while the non-equol producers’ dropped from about 48 mg/dL to about 46 mg/dL.

As for their LDL cholesterol, the equol producers’ fell from about 169 mg/dL to about 152 mg/dL. The non-equol producers’ fell from about 174 mg/dL to about 153 mg/dL.

The LDL reductions are large, the researchers reported in the American Journal of Clinical Nutrition, although that was likely because one of the three studies looked at weight reduction, and that would influence the results.

A 2006 review by the AHA nutrition committee of 22 randomized trials looking at soy and the levels of cholesterol said the LDL reduction they observed was relatively small in given the amount of soy a person would have to eat every day to achieve it.

Eating soy helps displace foods that can contribute to heart disease…

For example…”If you’re having a soy burger you may be displacing a hamburger,” they explained; “Overall, soy should only be one part of a cholesterol-lowering diet.” they concluded.
