Have you checked your brand of margarine lately? Do you know its percentage of trans fats and whether your favourite spread is actually good for you?
The Department of Health, Food Safety Division, has recently published its intention to ban all food products in South Africa with more than 2% trans fats. High levels of trans fats have been linked to breast and prostate cancers in international literature and, according to a Wikipedia statement some margarines can contain up to 15% trans fats.
The Cancer Association of South Africa (Cansa) took on the challenge to analyse the trans fat levels of 40 different magarines available in South Africa.
As far as the ideal composition of margarines is concerned, in terms of fatty acids, Cansa supports the following formula where all percentages are grams per 100 grams margarine:
- Trans fats below 2%
- Saturated fats below 10%
- Omega-3 fatty acid - higher than 4%
- Omega-6 to omega-3 ratio of 2.0 or less
A total of 40 margarines available in South Africa were purchased by Cansa from commercial outlets and submitted to the CSIR for fatty acid analyses. And, it was found that all of the margarines were below 2% trans fats (2 grams trans fats per 100 grams margarine).
Hard margarine = High saturated fat
“This is really good news,” says Dr Carl Albrecht, Cansa’s Head of Research. “It means that margarines in general do not pose a trans fat health threat as is often the case in other countries where hydrogenated oil, especially soya oil, is used.”
Margarines differ considerably in terms of saturated fat contents - the harder the margarine, the higher the concentration of saturated fat. Saturated fat is not essential to the body and should be taken in moderation. It is known to promote systemic inflammation with is associated with many diseases.
Margarines also vary considerably in terms of essential fats such as omega-3 and omega-6. Most margarines have a high omega-6 and little omega-3 content. South Africans in general are omega-3 deficient because they eat little food containing omega-3. An exception is Canola oil which contains 10-12% omega-3.
'Breeding ground' of cancer cells
According to Dr Albrecht, too much omega-6 fatty acid increases systemic inflammation that is the “breeding ground” of cancer cells.
“It is generally accepted that omega-6 needs to be balanced against omega-3 fatty acids in order to counteract inflammation optimally.” He adds that 28 out of the 40 margarines investigated contained less than one gram of omega-3 fatty acid per 100 grams of margarine.
The two top margarine stars in the study turned out to be Blossom Canola and Blossom Canola Light, manufactured by Epic Foods. “They have the highest concentration of Canola oil in South Africa,” says Albrecht, “which is the main reason why these brands have achieved Cansa’s revered ‘Smart Choice’ accolade.”
