Is organic food healthier?
This is a question every health conscious individual might raise,however,it's not just a simple yes or no question to answer.
To begin,we must first look into what constitute "organic foods".The definition given by Wiki says "Organic foods are foods that are produced using methods that do not involve modern artificial inputs such as pesticides and chemical fertilizers,do not contain genetically modified organisms,and are not processed using irradiation,industrial solvents,or chemical food additives.If livestock are involved,the livestock must be reared with regular access to pasture and without the routine use of antibiotics or growth hormones.
So much for that.Now how do ordinary people know the groceries they purchase from the market is truly organic or not?Currently,the European Union,the United States,Canada,Japan and many other countries require producers to obtain special certification in order to market food as "organic" .In order to get certified,the producers can expect frequent on-site testing conducted by government inspectors.So the true question becomes,do we trust our bereaucrats enough to rely on their test results and the certification process?
If your answer to this is Yes,then for sure the so-called "organic food" is not only safer,but also much more nutritious for us to consume and therefore,a lot healthier.
Another issue is the way the foods are prepared.You may now have all the healthy ingredients to prepare a meal,but the condiments you use and the cooking method can easily spoil the nutritional content of those costly raw material.It's something that everyone should think about,as well.
