Trans Fats and acrylamide in food increases atherosclerosis

From study: "Our in vivo studies in the group of healthy volunteers have shown that the consumption of potato chips rich in acrylamide cause the significant increase in plasma C-reactive protein and homocysteine concentrations. Enhanced CRP and HCY levels are accepted markers of enhanced atherosclerosis risk.

Acrylamide is a by product from the hydrogenation process.

In this study:

Lipids Medical Journal - 2004 Jan;39(1):11-8.

On Pub Med -

Trans, saturated, and unsaturated fat in foods in the United States prior to mandatory trans-fat labeling.

Quote from study: ( foods contain as much as 35.3% hydrogenated trans-fats)

The results showed that trans fat (g/100 g fat) ranged from 0.0 to 48.8 in bread, cake, and related products; from 14.9 to 27.7 in margarines; from 7.7 to 35.3 in cookies and crackers; from 24.7 to 38.2 in frozen potatoes; from 0.0 to 17.1 in salty snacks; from 0.0 to 13.2 in vegetable oils and shortenings; from 0.0 to 2.2 in salad dressings and mayonnaises; and from 0.0 to 2.0 in dry breakfast cereals. Serving sizes for the foods included in this survey ranged from 12 to 161 g, and trans-fat levels ranged from 0.0 to 7.2 g/serving. The significant differences in trans-fat content in products within each food category are due to differences in the type of fats and oils used in the manufacturing processes.

UPDATE - April - 2004 STUDY

J Nutr. 2004 Apr;134(4):874-9.
On Pub Med -

Trans fatty acids in adipose tissue and the food supply are associated with myocardial infarction. Quote from study:
"We conclude that TFAs in adipose tissue are associated with an increased risk of coronary artery disease and rapidly disappear from adipose tissue when not included in margarines."

Am J Clin Nutr. 2004 Apr;79(4):606-12.
On Pub Med -

Dietary intake of trans fatty acids and systemic inflammation in women.

Quote from study:
CONCLUSION: TFA intake is positively associated with markers of systemic inflammation in women.
UPDATE 11-20-2003

New study, October 2002, from Malaysia shows without question that trans fatty acids significantly raises LDL cholesterol and significantly lowers the good HDL cholesterol, thereby increasing risk of coronary heart diease. - Read this important new study HERE. This is just one of hundreds of new studies since I first wrote this column in 1998. On the new study page listed above, click on the related research articles at the top and it will take to to PubMED where is will list hundreds of new studies showing the dangerous health effects of these deadly hydrogenated oils.
UPDATE 8-20-2000 - Health Alert !

Mono-Diglycerides are nothing more than hydrogenated oils. Just a new name the food industry is using to fool the consumer that has become aware of the ill health effects of hydrogenated oils. Read this research report.

Dr. Uffe Ravnskov, M.D. PH.D, independent researcher from
Lund Sweden. This is a real eye shocker! Dr. Rasnosky blows
the myth apart about cholesterol and how cholesterol controlling
drugs produce cancer in rodents. The less fat you eat, the more your liver will produce cholesterol!
This is a must read, he provides links to the research data that supports his claims!
11:) Top Ten Deaths or
Top ten causes of death, U.S., 1998. When you compare this to 1985 and 1995 you see increases in all deaths. Heart disease shows a decrease...HOWEVER...this is attributable to the increase in medical technology that is keeping people living longer and does not show accurately the total number of peple being diagnosed with coronary heart disease. Many people that die from coronary heart disease usually die from other complications first, therefore their death is not reported due to heart disease, but some other cause.
