Tehran, May 15: Iranian households use cooking oil. Lots of it, as of 2004, a government survey found that more than 12 per cent of calories consumed were from partially hydrogenated vegetable oils, the main source of trans fats.
Trans fats included more than a third of the fatty acids in those oils, or nearly 5 per cent of daily calorie consumption—double the trans fat intake in the United States of America in 2007, according to a study published that year in the European Journal of Clinical Nutrition, a WHO report on Tuesday said.
“Most of the food consumed in the Middle East/North Africa region is high in fat, trans fat and total saturated fat,” says Dr. Ayoub Al-Jawaldeh, regional nutrition adviser for the WHO Eastern Mediterranean Region. “Food produced in our region is different from what is produced in Europe and North America. It has higher trans fat and uses palm oil.”
Over the past few decades, Iran has seen a steady increase in cardiovascular disease (CVD) and related risk factors. In 2010, Iran had the second-highest rate of CVD death and was third in trans fat intake out of 20 Middle Eastern and North African countries.
As cooking oil is used in such large quantities in Iran, it was among the first foods targeted for trans fat reduction. Between 2006 and 2013, trans fats were reduced in Iran from nearly 20 per cent in most edible oils and fats, to under 2 per cent.
According to the Ministry of Health and Medical Education in Iran, fractionation of vegetable oil—a technology that does not change the chemical nature of the fatty acids through controlled separation of oil and fat fractions—has been a common practice in Iran to replace partial hydrogenation.
As in other countries, the changes were phased in and required government agencies, civil society and industry to work together. The health and agriculture ministries, Iran Food and Drug Administration (FDA), oil manufacturers, nongovernmental organisations and oil importers all collaborated to reduce trans fats.
In 2005, the National Standards Organisation of Iran, the government arbiter, mandated a 10 per cent cap on trans fats in corn oil, palm oil, frying oil and mixed liquid oils—a reduction from the previous 20per cent. Government organisations were mandated to use oils with less than 10 per cent trans fat content.
The trans fat standards were reduced to less than 5 per cent in fats and oils in 2011, and to less than 2 per cent in 2013, with a 2016 compliance deadline. The ultimate goal is to limit trans fats to less than 1 per cent by 2019. According to the Iranian FDA, that target had already been reached by 2018.
Iran’s FDA Post Marketing Surveillance results showed that average trans fat of almost all of frying and liquid oils was below 1 per cent and within the acceptable limit, according a report on Iran’s efforts by the International Fund for Agricultural Development (IFAD) and National Nutrition and Food Technology Research Institute (NNFTRI).
While these measures reduced trans fat in cooking oil, regulations have not fully addressed trans fat in bakery products. The trans fat limit for margarine and shortening used in bakery products is 5 per cent, rather than 2 per cent. 
While there is still work to do to reduce trans fat in the food supply in Iran, the achievements so far have been impressive, particularly considering Iran had the highest recorded intake of trans fat in the world. 
“Iran has achieved a relatively safe position with trans fat levels in edible oils by regulating trans fats, using appropriate alternatives and by collaborating with food industries,” said Dr Ayoub Al-Jawaldeh. “As a pioneer in the region, Iran is now aiming to comply with WHO’s goal of to reduce premature mortality from non-communicable diseases by 25% by 2025. We need to reach 0 trans fat to achieve this goal.” UNI




          BUDGAM, MAY 2: Deputy Commissioner Budgam, Mohammad Harun Malik today inaugurated a daylong awareness cum screening camp about National Programme for Prevention and Control of Cancer, Diabetes, CVDs and Strokes here at DC office Budgam.
 Additional Deputy Commissioner Budgam, Mohammad Farooq Dar, Chief Medical Officer Dr GM Dar Medical Superintendent District Hospital Budgam Dr Deeba also attended the programme.
On the occasion, District NCD Cell Budgam held a free medical camp, where doctors checked scores of patients and provided free medicines to them.
 CMO Budgam, Dr GM Dar said that the programme has been recently started in the district. He said there are two cells, one working at district hospital Budgam and another at Sub-District hospital Chadoora with requisite staff under this programme.
           CMO said that the aim of the today’s awareness camp is to spread awareness and screening of people regarding non-communicable and old age diseases, so that people can change their lifestyle and the elements of BP, diabetes and CVDs and are diagnosed and rechecked to be treated earliest to decrease the death due to these diseases.
 He said that such programmes would be organized in every part of the district to take the campaign and related health services to people at their doorsteps.


New Delhi, Jan 8: India is the biggest consumer of Diamonds in the World. However, due to time consuming and intricate process for mining Diamonds from Earth there is an associated high cost. Thus there is need for the option, like many developed countries, to develop diamonds in the Lab. India is also working on this sophisticated Lab diamond technology which scientist believe will be the new luxury.
Diamond Synthesis or preparing diamond in Lab is not new to the world. Many scientists have tried to synthesize diamond using approaches somewhat similar to high pressure, high temperature (HPHT) method during the later parts of 18th and early 19th Century. 
Presently, USA, European Union, Russia, China, Japan, South Korea and Singapore have already developed various technologies and are producing lab diamonds. India,the biggest consumer of natural diamond, is still dependent on import and the concept of lab diamond is still unknown. Lab diamond is 15 to 20 per cent less expensive to the real natural diamond. Since the technology is intricate and demands rocket science level of attention for processing, it is still not in the reach of average consumer.
Several Labs in India are working on the preparation of diamond through Chemical Vapour Deposition (CVD) of carbon bearing molecules in plasma state. Currently CVD process is the preferred method due to lower cost of equipment, ease of operation, better quality of crystals and overall lower running costs of the process. All this is on research and development phase.
Acting Director,Dr. S.K. Mishra at CSIR Institute of Minerals and Materials Technology, Bhubaneswar, told UNI that CVD diamond is being pursued in several places such as in IMMT Bhubaneswar, CGCRI Kolkata, IIT-Madras Chennai, IIT Mumbai, BIT-Mesra Ranchi, and Technos Instruments Jaipur. 
Currently only colored gemstone and gem identification work is ongoing in Western India. However, there is no gemstone processing work going as yet in India, he added.There are two different ways to make synthetic or Lab diamond. Thus diamonds can be made in laboratory either by HPHT or by CVD method. 
Dr Mishra said, “At IMMT, we are able to make diamond coating (which consist of microscopic diamond crystals) in a microwave plasma CVD reactor. Although the process is quite complex.” He added that Gem grade diamond can be grown by the plasma CVD method using small seed crystals of diamond grown by HPHT method. The growth rate of diamond is quite slow so it takes about couple of weeks to get a millimetre size crystal! Diamond crystals with striking colour can be made by suitably doping boron, nitrogen and other elements or by introducing controlled amount of defects.
In 1954 GE (USA) scientists reported the formation of synthetic diamond by HPHT route by applying very high pressure (around 50,000 times atmospheric pressure and high temperature). However, growing large diamond crystals of interest for use as gems still require a complicated, very time and energy consuming process. For this reason, this process is very much prohibitive in cost and not practical.
Synthetic diamond seems to be the best future option but this will not displace the real diamond any time soon as there is not a larger cost difference. UNI
