Re: Fwd: High Carb Diets Don't Help Hearts from Discovery Health

[Guest guest]

Help! I'm confused. Or something. I'd really like to find the study you

mention in the text of your post, RC. The one published in the American

Journal of Cardiology. All I can see in the two links you provided is a

news article about the study. It is not referenced anywhere in these

pages. Nor is a low-carb diet recommended.

Can you help by pointing more directly to the Cardiology Journal report?

;-o Please?

(Meanwhile, I'll see what a search can turn up.)

I copied this info from a e newsletter I get from Discovery Health. The

newsletter didn't give a site for the study. You might try the Discover

Health site (www.discoveryhealth.com).

Study Finds High-Carb Diet Did Not Lower Heart Disease Risk

Jan. 31, 2000

Allan Sison

Medical PressCorps News Service

Maybe people shouldn't be eating high-carbohydrate, low-fat diets after all.

According to a new study, replacing saturated fats with carbohydrates did not

have the beneficial effects that experts thought it would.

Researchers led by Dr. Gerald Reaven, professor emeritus in the department of

endocrinology, gerontology and metabolism at the Stanford University School

of Medicine in Stanford, Calif., found that a high-carbohydrate, low-fat diet

resulted in higher levels in the blood of certain triglycerides a type of fat

and lower levels of high-density lipoproteins (HDL), the so-called good

cholesterol.

The diet, however, did not change the concentrations of low-density

lipoproteins (LDL), the so-called bad cholesterol. High levels of LDL are

associated with an increased risk of heart disease.

The researchers studied the effects of a high-carbohydrate, low-fat diet on

eight healthy volunteers. The subjects were randomly assigned to either a

high-carbohydrate diet, where 60 percent of the total calories came from

carbohydrates, or a low-carbohydrate diet, where 40 percent of the calories

came from carbohydrates. Each diet contained the same amount of total

calories.

The volunteers stayed on their respective diets for two weeks, ate normally

for two weeks and then were again randomly assigned to a diet.

Those who were on the 60 percent carbohydrate diet had higher levels of

triglycerides and another type of cholesterol called remnant lipoprotein

cholesterol (RLP), compared with those on the 40 percent carbohydrate diet.

These levels remained elevated over an eight-hour period, during which

breakfast and lunch were given.

The study is published in the January issue of the American Journal of

Cardiology.

" It confirms what has been previously reported, " said Alice Lichtenstein,

professor of nutrition at the Mayer USDA Human Nutrition Research Center

on Aging at Tufts University in Boston, and spokesperson for the American

Heart Association (www.americanheart.org).

Past studies have shown that high-carbohydrate, low-fat diets decrease levels

of HDL in the blood. Increases in triglyceride and RLP levels as a result of

the diet are new findings. RLP consists of concentrated remnants of fat that

remain in the blood after cells take the components of fat that they need.

These increases in triglyceride and RLP levels, along with lower HDL levels,

have been found to be associated with blockages in the blood vessels.

Lichtenstein noted that the two diets used in the study were opposite

extremes in terms of carbohydrate intake. " The critical points are that they

kept the calories the same and they kept the saturated fat the same, " she

said. Saturated fat is a major determinant of blood cholesterol levels.

Scientists have, for the most part, agreed that the intake of saturated fat

should be reduced. However, a suitable substitute for saturated fat has been

the source of debate.

" The bottom line is that when you drop the saturated fat in the diet, what do

you replace it with? " Lichtenstein remarked. " A very high carbohydrate diet

was detrimental in respect to lipoprotein profiles. The evidence suggests

that it should be replaced with unsaturated fat. "

" It is reasonable to suggest that the clinical use of current dietary

guidelines aimed at decreasing risk of coronary heart disease be

re-examined, " the researchers concluded.

I sure as heck can't find this exact item on Discovery Health. Don't know

what I'm doing wrong. Or why the links at the bottom don't work. But

they don't seem to! I did find a reference to the Journal of Cardiology

issue and page. Maybe it's because I am not signed up there??? I dunno.

It's frustrating.
