American consumer, the law makers and the Science-A big cauldron waiting to boil over!

Though genetically modified foods are predominantly produced and marketed in the United States, most consumers are either unaware of it or are helpless to do any thing to stem this trend of overwhelming GMO containing foods. The safety or otherwise of GMO foods is still a matter that divides humanity into opposing camps, one section finding no fault with them while the others vehemently loathing them. The gravity of the problem can be realized from the fact that even among scientists there is no consensus on this issue and how can one blame the consumer to take a stand on this burning issue. Whatever it is, in the US of to day consumers have no choice but to accept foods made from GMO raw materials and ingredients unless one has the wherewithal to spend a fortune to switch over to 100% organic foods. The fight that is going on to day in that country centers around the so called constitutional right of the citizen to know what he is eating and for that what they are asking is to just declare on the label of products whether GMO ingredients are there or not in the food packet. A well reasoned demand though the industry, politicians and bureaucrats do not think so, obviously because of pecuniary considerations.

Look at the stand taken by the safety watch dogs in that country viz Food and Drug Administration and US Dept of Agriculture both of which considers genetically altered foods "practically" same as their natural counterparts and therefore felt there is no need to specifically mention about their presence in any food on the label. One is left with the impression that the US wants to be a unique country in swimming against international views on almost all issues, probably because of the arrogance of power, being the only super power left in the global landscape after the demise of erstwhile Soviet Union. Other wise it is difficult to explain why it is cocking a snook at 64 other countries which have made label declaration about GMO foods mandatory! Why is this happening in a country which is supposed to be the beacon for all democracies in the world? Obvious answer is the nexus among politicians, bureaucrats and industry lobbyists to deny the consumer his right and make unholy money for their own welfare!

A peep into the American situation will reveal this paradox. According to recent reports a fierce food fight is going on in the Congress over the labeling of genetically engineered foods.with a substantial section of the law makers trying to block any move to enforce mandatory labeling of GMO foods in any part of the country. Is it not a paradox that in a federal system of governance, where states enjoy high degree of freedom to legislate, their right is being usurped by the federal government through an insidious bill that will block the power of states to enact any law that will mandate compulsory labeling of GMO foods! Who are these law makers trying to help? Of course the GMO industry giants who have a stranglehold on the American economy through their close nexus with politicians. This attempt comes in the wake of three states already putting on the statute book law that requires labeling of foods marketed in their area. Attempts in the past by some big states like California to legislate on similar lines were frustrated by saturated misleading campaign by the GMO lobby pumping millions of dollars to brain wash the voters. 
.
The attempt to pass a law called "Safe and Accurate Food Labeling Act" if passed asks for setting up a voluntary nationwide labeling system overseen by the federal government. This bill, popularly renamed by the consumer activist groups as "DARK Act", acronym for Deny All the Right to Know" Act! Protagonists of GMO foods invariably argue that about 90 percent of the corn, soybeans and cotton grown in the U.S. are genetically engineered, meaning that the crops have been artificially altered to use less water or resist pests and no calamity has befallen in the country. Also other supporters cite the clearance given by The American Association for the Advancement of Science, the American Medical Association and the World Health Organization all of them who have deemed all GMOs on the market as safe. 
However a major chunk of the consumer community is not convinced fully about the safety of such foods because of the common perception that industry does not have the well being of the citizens in their mind, relentlessly pursuing efforts to increase their profits and the scandals surrounding presence of unsafe chemicals hormones, steroids, transfats,etc further reinforce their distrust about the products churned out by the manufacturers. 

At present there are no government-approved labels to let consumers in the U.S. know which foods are derived from GMOs.It is funny that the US Government wants to leave to individual manufacturers to make any label declaration to indicate that their products are free from GMO ingredients without taking any responsibility to verify such claims! That has prompted many companies to advertise their food as "Non-GMO" by taking the services of existing Non-GMO Project which is a private nonprofit outfit floated by retailers. The group is claimed to be testing food products and do product segregation practices to verify that products with its butterfly seal contain less than 1 percent GMO ingredients. Can it be a long term solution when millions of consumers expect their government to come to their rescue by overseeing such label claims to infuse confidence in such products? If mandatory labeling is anathema to the political class which runs the country, least they can do is to set up a dedicated authority to verify claims of manufacturers that their products are free from GMO substances.Will this happen?  Depends on the intensity of struggle by the consumers on the government to sensitize them on this critical issue.

THE ANTIOXIDANT DATA BASE-A NEW CHILEAN INITIATIVE

Antioxidants are to day more or less recognized as the saviors of mankind from many non-infectious diseases like cancer. Such a situation has come about after it was found by many scientific studies about the ability of antioxidants to scavenge free radicals from the body. Oxy radicals generated in the human body due to various metabolic reactions, if not removed promptly, are believed to cause damage to DNA which can cause various types of cancers affecting different organs and other vital functions. It is believed that fruits provide high levels of antioxidants, mainly in the form of poly phenols and a generous consumption of these protective foods can keep many diseases away. The latest dietary recommendations suggest that almost half the plate of foods consumed every day should be contributed by fruits and vegetables.

It is believed that human body makes its own anti oxidants to neutralize the day to day generation of oxy radicals there by protecting it from many serious diseases but modern day life contributes a much larger levels of oxy radicals which need more anti oxidants to make them innocuous. Optimum health to day means ensuring taking adequate amounts of anti oxidants through daily diet. This naturally raises the question regarding the relative efficiency of various food sources in providing high levels of antioxidants to the body. Poly phenols which are natural constituents of many foods consumed daily are considered to be of efficient antioxidant credentials though there is always the question of their absorption across the GI tract under normal conditions. For these antioxidants to be effective they are required to be delivered to the cells in their active form and it is here where some confusion still exists. If a product claims it is rich in antioxidants, it may not be telling a lie but if the claim refers to health advantages by consuming them, same may not be tenable because of uncertainties regarding the actual absorption and delivery to the cells for making them work.

ORAC Value proposed by the National Institute on Aging under National Institution of Health, Bethesda, USA is widely used to assess the efficacy of foods as a source of antioxidants. ORAC value simply predicts the Oxygen Radical Absorbance Capacity of a substance through laboratory analyzes and is widely used in estimating the antioxidant value of different foods. It was the USDA which first brought out a compendium of foods with different ORAC values to help the consumers to select antioxidant rich foods in their daily diet. Recently the Institute of Nutrition and Food Technology in Chile has brought out the ORAC values of 140 different fruits grown all over the world, besides providing useful information about other nutrients present in them. Unfortunately the world has not reached a stage where ORAC values can be used as a reliable indicator for making legally health claims by different food resources. But it till serves the purpose of helping the consumers to select the ones with highest ORAC value for his continued well being. 

Many people may be unaware that Sorghum, considered a poor man's staple in many countries is a rich source of antioxidants boasting of a high ORAC value of 45,400! Compare this with the ORAC value of 290,285 for a spice like Cloves or 131, 420 for Cinnamon or 127,068 for Turmeric. The much ridiculed Curry Powder of India can boast of an ORAC value of 48, 504. Some times it is intriguing to see many published scientific papers touting about high ORAC values for fruits like Blackberries, Blueberries and other berries like Calafate, Macqui, Murtilla etc because these are not produced in substantial quantities to be available year around, if the demand rises rapidly. Besides they are not consumed in big quantities to deliver high levels of antioxidants. On the other hand take the case of foods like Sorghum which is taken to meet bulk of the energy needs in some parts of the world and the impact can be quite high. Of course a good balanced diet containing different sources of antioxidants like Berries and other colored fruits and vegetables, grains like Sorghum, Spices like Turmeric, Cumin, Black Pepper etc will always be a sure bet against accumulation of Oxy radicals in the body as they can effectively scavenge them regularly. 

The Compilations by the USDA and the Chile Institute are considered a great service to humanity because of the educational value they have on the food consumption behavior of the population at large. With such readily available data, industry must be encouraged to use ORAC value of every food marketed by it and such a step can hope to tide over the increasing wave of Cancer and other diseases in the coming years.
