Transvetzuren in voeding



logo.jpg (8782 bytes)


Waarom deze site ?

Via deze site willen wij het Nederlandse publiek waarschuwen voor de grote gevaren van transvetzuren in onze voeding. In Amerika, Canada en Denemarken zijn de overheden streng opgetreden tegen deze gevaarlijke vetzuren in de voeding waardoor veel fabrikanten gedwongen worden om hun produkten aan te passen gezien de grote risico's voor de consument.

De voedingsindustrie in Amerika en Canada is genoodzaakt te stoppen met het gebruiken van (gedeeltelijke) geharde plantaardig vet in haar produkten, alleen de fastfood industrie heeft nog weinig aanpassingen gedaan tot nu toe.

De Nederlandse consument is nog niet op de hoogte van de zaken die spelen in Amerika, Canada, Denemarken en nu ook in Nederland en dat wordt hoog tijd. Transvetzuren zijn een regelrechte ramp voor onze gezondheid en te lang doodgezwegen. Tijd voor aktie dus.


Wat willen wij bereiken ?

  • Bekendheid van dit probleem bij de Nederlandse consumenten
  • Verbod op transvetzuren in voeding en fastfood
  • Suggesties bieden voor alternatieven
  • Aandacht geven aan produkten die vrij zijn van transvetzuren

Gevaarlijker dan verzadige vetten

In Nederland is altijd de boosdoener verzadigd vet geweest en werden roomboter, kokosvet, palmvet in de ban gedaan en vervangen door verharde oliën en margarines. Maar nu blijkt dat juist de transvetzuren die ontstaan bij verharding van onverzadigde oliën een veel groter gevaar voor de gezondheid zijn.



Wat zijn transvetzuren ?

Transvetzuren ontstaan bij hydrogenering van plantaardige vloeibare olie (zonnebloemolie, sojaolie etc) naar vaste vetten, deze vetten blijven langer houdbaar en worden oa gebruikt voor het bakken van fastfood, chips, bakkerijprodukten, patat etc. Terwijl men in Nederland bang is gemaakt voor verzadigde dierlijke vetten vergeet men de echte gevaarlijke vetten in de industriefood en fastfood produkten.

Op de labels van produkten staan echter alleen de waardes van verzadigd vet maar niet de waardes van de veel gevaarlijker transvetzuren die volop aanwezig zijn in de fastfood/industrie voeding.

 

Wat doen transvetzuren ?

  • Zorgen voor een verhoogde kans op aderverkalking
  • Hebben negatieve effecten op groei van de foetus
  • Zorgen voor een verhoogde kans op diabetes
  • Zorgen voor 10 keer grotere kans op hart en vaatziektes
  • Zorgen voor verhoogde kans op allergie bij kinderen
  • Amerikaanse onderzoekers noemen ook een verhoogde kans op galstenen bij mensen die een hogere inname van transvetzuren hebben.

 

Meer doden door transvetten dan in het verkeer !

En wat doet de overheid? Helemaal niets, in dit geval wordt de vervuiler beloond en kijkt de overheid toe. Dit noemen ze in Den Haag preventie.

 

Waar zitten ze in ?

Op deze pagina zijn we bezig een lijst samen te stellen van voeding die geharde vetten bevat aangezien de supermarkten en de overheid nog altijd geen eisen stellen op dit gebied willen we de transvetzuren zichtbaarder maken voor de consument

De actuele lijst: http://www.fonteine.com/transvetlijst.html

 

 

Video - De Gevaren van Transvet, (gedeeltelijk) gehard vet, geharde olie

Transvetten (transvetzuren) zijn kunstmatig gefabriceerde vetten die zeer slecht zijn voor uw gezondheid. De gezondheids risico's van transvetten: obesitas, kanker, dichtslibben van de aderen, geboorte afwijkingen, diabetes, hoge cholesterol, hart en vaatziektes, allergie bij kinderen, etc.

Voedingsproducten bevatten transvet als er één van de volgende ingredienten bevat: (gedeeltelijk) gehard vet, (gedeeltelijk) geharde olie, gehydrogeneerde vet/olie.

Doe uw gezondheid een plezier en verwijder deze chemische substantie uit uw voeding!

Transvetzuren zorgen voor dikkere babies

Opnieuw een hoofdrol voor transvetzuren, de zogenaamde geharde plantaardige vetten, die met name voorkomen in industrievoeding, fabrieksbrood (supermarkten zoals Aldi, Plus etc etc ) en het beruchte koffiemelkpoeder (1/3 gehard vet!!) dat sommige mensen iedere dag in hun koffie doen (met name koffiemachines op het werk). Ditmaal een relatie tussen inname van transvetzuren door zwangere moeders en het effect op het vet van de baby. Bij ratten zorgde dit voor 40% vettoename en verhoogde insuline produktie (dus meer kans op diabetes 2).

Vermijdt dus alles dat geharde plantaardige vetten bevat, de supermarkten liggen er vol mee, fabrikanten blijven deze ziekmakers dag in dag uit gebruiker omdat ze goedkoop zijn, ten kosten van uw gezondheid !

Pregnant mothers' diet linked to baby's obesity
Pregnant and lactating rats fed on a diet of hydrogenated fat during pregnancy and lactation had babies who were fatter than rats fed a normal diet, according to research published in Lipids in Health and Disease. The unhealthy diet has deleterious consequences even after the fats were removed from the diet and has links to insulin production.

“We know that foetal growth is influenced by the mother’s nutritional status,” explained Brazilian nutritionist Luciana Pisani. ”The nutritional conditions during pregnancy has a major role in the metabolic and hormonal interactions between the mother’s body, placenta and foetus. To date only a few studies have looked at the effects on trans fatty acids during pregnancy and lactation on the metabolism of offspring in adulthood. We found that the fatty content of the babies’ bodies increased when the mothers were fed the hydrogenated fat rich diet and this could be traced to the gene expression of adipokines.”

In an investigation to examine whether feeding pregnant and lactating rats hydrogenised fats rich in trans fatty acids, increased the fat content in carcass, the researchers found that their metabolic rate dropped dramatically. Interestingly young rats that were fed a normal diet after they were born ate less and weighed less even though their mothers had been eating the trans fatty acids while pregnant. The gene expression of adipokines was also examined in relation to insulin production.

The offspring were weighed weekly and exposure to the trans-fatty acid enriched diet after weaning led to a 40% increase in body fat content for the young rats. Rats whose mothers were fed the trans fatty acids and continued to eat the fats into adulthood had the highest metabolic efficiency. The same rats increased their insulin production.

Pisani continued, “Fats play a fundamental role in foetal development and changes in dietary fatty acids has important implications for foetal and postnatal development. Heavy ingestion of very hydrogenated fats rich in trans fatty acids increases risk of cardiovascular diseases and reduces insulin sensitivity and so leads to type 2 diabetes. We need to investigate this further as this has important implications for people’s own diets, especially pregnant women.”

Transvetzuren (gehard plantaardig vet) slecht voor  neurlogische ontwikkeling kinderen

Recentelijk is er onderzoek gedaan naar de relatie tussen de neonatale transvetzuur status en de neurologische ontwikkeling van gezonde op tijd geboren kinderen. Er kwam uit naar voren dat hoe meer transvetzuren er in de navelstreng van het kind zaten des te slechter de neurologische conditie van het kind op 18 maanden. Dit is de eerste keer dat de relatie tussen transvetzuren en neurologische ontwikkeling in een grote groep bekeken is.

Wat doet de Amerikaanse overheid ?

In Amerika is sinds 1-1-2006 verplicht dat op voeding de hoeveelheid transvetzuren vermeldt moeten staan op de labels. Dit heeft voor grotere verschuivingen gezorgd in de samenstelling van voedingswaar. Grote chips fabrikanten moesten snel op zoek naar gezondere ingrediënten als alternatief voor geharde vetten. Dit betekent dat produkten in Europa vaak nog de oude ongezonde stoffen bevatten. De fastfood industrie blijkt nog geen drastische stappen te hebben genomen en levert gewoon nog steeds produkten die veel transvetzuren bevatten. Met name het appelgebak, franse frietjes en de ontbijt menu's. De FDA adviseert een inname van hooguit 1-2 gram transvetzuren per dag terwijl een zakje Franse frietjes al gauw 5-8 gram bevat. Al bij 1 gram per dag heeft dit nadelige gevolgen
voor je gezondheid.

Wat doet de Deense overheid ?

De Deense overheid heeft al in 2003 drastisch stappen genomen om haar bevolking te beschermen tegen deze gevaarlijke vetzuren. Het is te hopen dat in 2006 ook het muntje valt bij de heren in Den Haag.....


Nederland in Europa nr 2 qua inname

In 1996 stond Nederland samen met Ijsland bovenaan de Europese lijst qua inname per persoon van transvetzuren (4.3 gram per dag). Laagste land was Griekenland met gemiddeld 1.4 gram per persoon per dag.

Wat gebeurt er in Engeland ?

In Engeland komt er ook steeds meer verzet tegen produkten met transvetzuren. Men wil dat Europa Denenmarken gaat volgen en het publiek informeert over de hoeveelheden transvetzuren in produkten zodat de consument weet wat hij koopt. Een mogelijk alternatief voor harde plantaardige vetten zou palmvet/kokosvet kunnen zijn. Een groot bekend warenhuis (Mark en Spencer) heeft transvetten per 1/6/2006 in de ban gedaan, men wil dit soort produkten niet meer verkopen.

Artikelen en achtergrond informatie


De echte waarheid over goede en slechte vetten

vetten die doden Wil je alles weten over gezonde vetten ?. Dan is dit het beste boek dat je kunt lezen waarin de waarheid over vet wordt verteld. Het is geschreven door Dr Enig en is het belangrijkste naslagwerk op het gebied van vetten, oliën en cholesterol. Zij zegt bijvoorbeeld over vet: “Het idee dat verzadigd vet hartziekten veroorzaakt is volkomen verkeerd! Maar deze vetgedachte is door de vele campagnes zo diep in de hersenen van de mensen gestampt dat het moeilijk is hen te overtuigen van het tegendeel, tenzij ze er iets over willen lezen op diverse websites.”

Andere wetenschappelijke vetexperts bevestigen de bovengenoemde uitspraken. Enkele daarvan zijn Michael Gurr (prof en biochemicus in Oxford), George Mann (prof en biochemicus Vanderbilt universiteit), Michael Oliver (prof Wynn instituut voor metabolisch onderzoek Londen), Raymond Reiser (prof en biochemicus universiteit Texas), Paul Rosch (prof, medisch college New York).

Deense overheid neemt risico's wel serieus

A debate on the phasing-out of industrially produced trans fatty acids in food products has been initiated over the last few years in the EU, and particularly in the USA. In Denmark, this debate started in 1994 following the publication of the Danish Nutrition Council’s first report, which actually dealt with trans fatty acids and contributed to a significant fall in the consumption of these fatty acids by Danes.

On March 11, 2003 the Danish government decided to phase out the use of industrially produced trans fatty acids in food before the end of 2003. We hope that this report can provide a useful tool in work on eliminating these fatty acids, which are harmful to health, from food products, also in countries outside Denmark.

The report ‘The influence of trans fatty acids on health’ published
in 1994 by the Danish Nutrition Council concluded that trans
fatty acids in the diet promote arteriosclerosis at least as much as
equivalent amounts of saturated fats and probably more, and that
there are justified suspicions that a high trans fatty acid intake may
have adverse effects on foetal growth. It was therefore recommended
that a declaration of trans fatty acid levels in foodstuffs be dealt
with by the EU. An agreement was also concluded with the Danish
margarine industry to reduce the trans fatty acid content of margarines
produced in Denmark.

Since 1994, the influence of a high intake of industrially produced
trans fatty acids in promoting the development of heart disease has
been further documented by, among other things, the presentation of
four major prospective population studies. The studies indicate that,
gram for gram, the intake of trans fatty acids as compared with saturated
fatty acids is associated with an approximately 10-fold higher risk
increment for the development of heart disease. The suspicion of an
adverse effect of trans fatty acids early in life has been further confirmed.
The possible effect of trans fatty acids on the development of cancer is
still unclarified. Data from both epidemiological and mechanism
studies gives rise to the justified suspicion that trans fatty acids increase
the risk of type 2 diabetes. Studies have also been presented justifying
further studies concerning the possible effect of trans fatty acids in
promoting allergic diseases in children and concerning the possible
influence of trans fatty acids on body fat distribution and insulin
sensitivity.

Why fast foods are bad, even in moderation

Monkeys fed a diet rich in trans-fats – commonly found in fast foods – grew bigger bellies than those fed a diet rich in unsaturated fats, but containing the same overall number of calories. They also developed signs of insulin resistance, which is an early indicator of diabetes.

Food Industry Mulls Dropping Obesity-Linked Trans Fats

Trans fats have been fingered as a major culprit in America's bourgeoning obesity problem, in increasing the risk of heart disease - and they are possibly also a factor behind childhood allergies, asthma, and other conditions.

The Danger of Hydrogenated or Partially Hydrogenated Fats

Increases blood insulin levels in humans in response to glucose load, increasing risk for diabetes;
Raises the LDL cholesterol in a dose response manner;
Lowers the "good" HDL cholesterol in a dose response manner (the higher the trans level in the diet, the lower the HDL cholesterol in the serum);

Fight against trans fats by Pat Martin

A gram of trans fat is four- to ten times more dangerous to heart health than a gram of saturated fat, and the World Health Organization has recommended countries move – as Denmark did last year – to eliminate transfats. At about 10 grams a day, Canada has one of the world’s highest consumption rates of transfats. The New England Journal of Medicine says consuming one gram a day increases the risk of heart disease by 20 per cent.

"Families want protection from dangerous trans fats and the NDP’s calling on all parties to provide it," said Layton. "Canada should move as quickly as we can to get dangerous transfats out of the food our families eat. Let’s show Ottawa can listen to people and respond to their concerns – and improve public health in the process.

"Transfats are found everywhere and are a clear danger to Canadians’ hearts," said Layton. "And with transfats being most prevalent in highly processed foods, low-income and older Canadians are particularly at risk. It’s time to act against transfats, and pass sensible legislation that requires the food industry to get it out of families’ food faster."

Trans fatty acids on labels per 1 jan 2006

The Food and Drug Administration (FDA) now requires food manufacturers to list trans fat (i.e., trans fatty acids) on Nutrition Facts and some Supplement Facts panels. Scientific evidence shows that consumption of saturated fat, trans fat, and dietary cholesterol raises low-density lipoprotein (LDL or "bad") cholesterol levels that increase the risk of coronary heart disease (CHD). According to the National Heart, Lung, and Blood Institute of the National Institutes of Health, over 12.5 million Americans suffer from CHD, and more than 500,000 die each year. This makes CHD one of the leading causes of death in the United States today.

FDA has required that saturated fat and dietary cholesterol be listed on the food label since 1993. By adding trans fat on the Nutrition Facts panel (required by January 1, 2006), consumers now know for the first time how much of all three -- saturated fat, trans fat, and cholesterol -- are in the foods they choose. Identifying saturated fat, trans fat, and cholesterol on the food label gives consumers information to make heart-healthy food choices that help them reduce their risk of CHD.

This revised label, which includes information on trans fat as well as saturated fat and cholesterol, will be of particular interest to people concerned about high blood cholesterol and heart disease. However, all Americans should be aware of the risk posed by consuming too much saturated fat, trans fat, and cholesterol. But what is trans fat, and how can you limit the amount of this fat in your diet?

Trans fat information is coming to a food label near you!

This really is big news. For years you've probably been avoiding saturated fats in foods while trans fats have escaped unnoticed. These "stealth fats" will no longer be able to hide in food and do their damage to your health without your knowledge. The Food and Drug Administration established a rule in 2003 requiring food manufacturers and makers of some dietary supplements to include trans fat information on the nutrition label of their products. All food labels must include this information by 2006, although some manufacturers are beginning to make the change already.

While reviewing guidelines on daily requirements for protein, fat, and carbohydrates, the Institute of Medicine drafted a letter to the Food and Drug Administration on trans fats. Here's the institute's bottom line: There's no safe daily level for trans fat intake, and we should eat as little of them as possible.

That might be easier to do if you could tell if trans fats are in a food and, if they are, how much it contains. Take one of Entenmann's Rich Frosted Donuts. According to the Center for Science in the Public Interest, the five grams of saturated fat listed on its label are bad enough. But when you add in the unlisted five grams of trans fat, the total is half a day's allotment of unhealthy fat.

McDonald's finds More Trans Fat in its Fries

New tests find that McDonald's French fries contain higher levels of trans fats than previously disclosed. The new tests found 8 grams of trans fats in a large servinig of fries -- one-third more than McDonald's claimed. Trans fats contribute to harmful cholesterol buildup and heart disease. Official U.S. government dietary guidelines recommend next to zero consumption of trans fats.

Trans fats raise gallstone risk

Our results suggest that a higher intake of trans-fatty acids modestly increases risk of gallstone disease. This adds to the concern that partial hydrogenation of vegetable oils to form shortening and margarine can lead to adverse health effects,” conclude the researchers in the May 9 issue of the Archives of Internal Medicine.

The killer in your cupboard

The European Food Safety Authority has said that they may cause more damage than saturated fats. Some think that as little as 1g a day will significantly increase your risk of heart disease." Trans fats raise the levels of "bad" (LDL) cholesterol in the blood, and lower the levels of "good" (HDL) cholesterol, so increasing your risk of coronary heart disease. They have also been linked to type-2 diabetes.

Marks & Spencer bans hydrogenated fats

Marks & Spencer’s commitment to remove all hydrogenated fats from its entire food range by mid 2006 suggests that awareness of trans fats has now fully hit Europe.

The firm is the first major retailer in the UK to place a blanket ban on hydrogenated fats, and could set in place a trend that snowballs, with consumer choice increasingly informed by health and nutritional knowledge.

Studies mbt de gevaren van transvetzuren


Trans fatty acids and diabetes mellitus

Salmerón J, Dr., Unidad de Investigación Epidemiológica y en Servicios de Salud,Instituto Mexicano del Seguro Social, Cuernavaca Morelos, México.

Conclusions: These data suggest that total fat and saturated and monounsatu-rated fatty acid intakes are not associated with risk of type 2 diabetes in women,but that trans fatty acids increase and polyunsaturated fatty acids reduce risk. Substituting nonhydrogenated polyunsaturated fatty acids for trans fatty acids would likely reduce the risk of type 2 diabetes substantially.
