Organic foods are not only better for you, but they are better for the environment too! They are grown naturally and they avoid the use of pesticides which are harmful to the environment. Organic foods are also very healthy as they contain 50% more of nutrients, vitamins and minerals than produce that has been intensively farmed.
Yes, it may be more costly, however, take into consideration that you will be doing yourself more good than harm if you purchase organic foods, such as fruits and vegetables more often. The food tastes fresh and much better as there are no chemicals or hormones used to produce them, which tend to destroy the taste!
In Dubai, we have a great organic supermarket called "Organic Foods and Café" (http://www.organicfoodsandcafe.com/index.php) that not only sells organic and biodynamic food, but products like cosmetics, baby items and household cleaning products that are organic, too! There are a number of outlets that can be found around Dubai, and "the Organic Foods and Café is the only certified organic outlet in the Middle East and largest supplier of organic products in the world."
So, find out if you have an organic supermarket in your city or country and try to start investing more in purchasing more organic produce. The result will be a healthier you and a healthier environment!
