Trans fatty sids-Trans Fats | American Heart Association

Your body needs dietary fats in order to function. And the new thinking is that trying to cut out all fats from your diet may actually be contributing to obesity. One key to heart health is the type of fat you eat. All fats contain the same number of calories—9 calories per gram. But the three main types have different effects in the body.

Trans fatty acids TFA are produced either by hydrogenation of unsaturated oils or by biohydrogenation in the stomach of ruminant animals. Vanaspati ghee and margarine have high contents of TFA.

There is high prevalence of CVD in Pakistan. High consumption of vanaspati ghee which contains Public awareness about the adverse effects of TFA on human health would be extremely important. Media can play a very effective role in educating the masses and advocating the policy for the sale of only low TFA food items. Trans fatty acids: Trans fatty acids TFA by definition are geometric isomers of monounsaturated and polyunsaturated fatty acids having at least one carbon-carbon double bond with hydrogens on opposite sides of the double bond trans configuration.

They arise either by partial hydrogenation of unsaturated oils usually in the presence of nickel or by biohydrogenation in the rumens of cows and sheep. Trans fatty acids in food items: Margarine, vanaspati ghee, bakery and frying fats and vegetable shortenings are obtained through industrial hydrogenation and contain significant amounts of TFA.

Since their contents vary from one food item to another, it is difficult to estimate their consumption in various countries. However, in USA it is estimated to be energy percent, while in some of the countries in Middle East and South Asia, it could be as high as 7 energy percent. Hard-type margarine samples in Pakistan contained TFA in the range of 1.

Trans fatty acids and cardiovascular disease: As the adverse effects of dietary saturated fatty acids became known, TFA were considered to be a safe replacement of butter fat.

Ruminant TFA: Ruminant TFA which are produced by biohydrogenation in stomach of ruminant animals include vaccenic acid and rumenic acid which is a conjugated linoleic acid isomer. Reformulation of food products is an effective way of reducing TFA. For example, in USA, trans fat contents were reduced to less than 0. Fat interesterification : Interesterified fat is a type of oil where the fatty acids have been moved from one triglyceride molecule to another.

Interesterification of vegetable oils can replace an unsaturated fatty acid such as oleic acid or linoleic acid at the middle position sn-2 of glycerol by a saturated fatty acid stearic acid with the help of catalysts or lipase enzyme.

However, more research is required in this field with focus on the effect of interesterified fat on inflammatory markers. Genetically modified fatty acids: Using genetic engineering, fatty acids with desired characteristics can be obtained and then through reformulation the TFA contents of food products can be reduced. There is an epidemic of CVD in Pakistan. TFA adverse effects on CVD are well established, therefore, their consumption should be brought to a minimum level by the following methods:.

Substitution of natural plant oils containing lower percent of polyunsaturated fatty acids for vanaspati. Frying has been found to result into the formation of TFA. Adoption of gentle-frying or steam-frying of food is going to reduce TFA formation in these food items. This would be an effective process of preparing healthy food in our homes.

In the Cardiovascular Health Study, it has been shown that increased consumption of fried fish sandwiches was associated with increased risk of CVD.

Repeated use of cooking oil is a common practice in Pakistan. TFA contents are already high in hydrogenated vegetable oils and these would increase further after repeated frying.

Recent research has indicated that high intake of dairy saturated fat is associated with decreased risk of CVD, while higher intake of meat saturated fat has been found to be associated with greater CVD risk. Media can play a major role in public advocacy. Laws should be promulgated by the Government to introduce mandatory labeling for information of TFA and saturated fat content on packs of vanaspati oil, edible oil and other oil products.

In summary, a multipronged approach involving both public and private sectors would be needed to reduce the burden of CVD in South Asia through the adoption of healthy foods. National Center for Biotechnology Information , U.

Fats and Your Food: Striking a Heart-Smart Balance | Johns Hopkins Medicine

There is new evidence about what might be behind the leading cause of death among infants in the United States — Sudden Infant Death Syndrome. News and World Report explains :.

Partly that is because there are so many interpretations of what constitutes a SIDS death. The CDC says :. SIDS cases have declined nationwide in recent years. The National Conference of State Legislatures says :. It is fairly detailed. Almost all 50 states have some SIDS legislation on the books.

Most of the laws deal with reporting deaths and training emergency and child-care workers. Here is a list of state laws for you. While SIDS cases nationwide have dropped, the death rate in child-care settings has been fairly steady. It also lists some risk factors for SIDS:. Overheating Infants who overheat because they are overdressed, have too many blankets on, or are in a room that is too hot are at a higher risk of SIDS. Also infants exposed to smoke at home or at daycare are more likely to die from SIDS.

Preterm and low-birth-weight infants Infants born premature or low birth weight are more likely to die from SIDS. In the last week, a change has begun that may shape social networking and file sharing sites in significant ways.

Will it spell the downfall of YouTube and MySpace? It seems to me that the sharing of copyrighted material is one of the reasons people use these sites. The Washington Post says:. Six of the top 20 most-watched videos on YouTube. Posting copyrighted clips violates the Digital Millennium Copyright Act. Rival site Guba , which has about 2 million monthly users, has its own filtering technology that blocks copyrighted goods from being posted more than once.

The Associated Press says:. An average American eats 4. I have been seeing stories, like this one , that report school systems are removing trans fats from lunches. Denmark declared war on trans fats a couple of years ago, and threatened offenders with hefty fines. ABC News reports:. The Danish health ministry reports that cardiovascular disease has fallen by 20 percent in the last five years. However, other countries have reported similar drops in heart disease where smoking has been restricted and where industry has made efforts to improve some foods.

In countries that are making no effort to regulate the amount of trans fat in food, such as Hungary and Bulgaria, heart disease rates have continued to climb. Denmark is the only country to have so sharply limited trans fats, passing a law in that came into effect in , making it illegal for any food to contain more than 2 percent of trans fat.

Sometimes customers fight back when manufacturers change to healthier recipes. One potato-chip manufacturer was flooded with complaints and switched back to the trans-fat recipe.

October 31, Al Tompkins. Al's Morning Meeting MediaWire. Category: Uncategorized. Now, doctors say, they have unearthed the strongest evidence yet that a region in the brain that controls breathing is abnormal in infants who die of SIDS. They focused on the medulla, an area in the brain stem that controls involuntary actions like breathing, blood pressure, and heart rate that has been the focus of much SIDS research.

The abnormalities were more extensive than those found in earlier studies. No one knows what causes the abnormalities in SIDS-prone babies. Other researchers disagree, and are looking for birth stresses or environmental factors in early life that could account for the problem.

A child without the brain abnormalities would have no problem sleeping face down, but a SIDS-prone child might. Each year in the United States, more than 4, infants die suddenly of no obvious cause.

This finding suggests that changes in reporting of cause of death may account for part of the recent decrease in SIDS rates. By definition, SIDS can only be diagnosed after a thorough examination of the death scene, a review of the clinical history, and performance of an autopsy fail to find an explanation for the death. And yet we know that some SUID are not investigated and, when they are, cause-of-death data are not collected and reported consistently.

This is concerning because inaccurate classification of cause and manner of death ultimately impedes prevention efforts because researchers cannot adequately monitor national trends or evaluate prevention programs. One important factor credited by experts is the campaign to encourage parents to place infants on their backs to sleep. The American Academy of Pediatrics has been instrumental in the campaign. The Maternal and Child Health Bureau also launched a new effort to educate childcare workers about the importance of placing babies on their backs to sleep.

Tummy prone or side-sleeping Infants who are put to sleep on their tummy or side are more likely to die from SIDS than infants who sleep on their backs.

Sleeping on a waterbed, couch, sofa or pillows, or sleeping with stuffed toys has been associated with an increased risk for SIDS. Featured Jobs.
