Production of food and its preservation for long time may involve addition of chemicals. Hence, chemical substances can play an important role in food production and preservation. For.e.g. the additives in the food prolong the shelf life of foods; colours, make food more attractive. Flavouring agents like aldehydes make food tastier. Unlike any other industry, agriculture is also a part of industry. The agriculture industry relies heavily on large number of chemicals which may be toxic in nature. Some of these chemicals may get absorbed by our body. Accordingly the use of chemicals involved in production, harvesting (collection), processing, packing, transport, marketing and consumption creates deleterious effect on both human and ecology. Majority of the additives in the food may lead to headache, nausea, weakness and difficulty in breathing. The research on nerve cells has shown these chemicals to cause toxic effect on nerve cells. Although the toxicants cannot be avoided, but the level can be reduced by adopting or making use of organic, sustainable and less toxic options.

Honey is a natural sweet substance produced by honey bees. Honey has a very complex chemical composition that varies depending on the botanical source. It has been used both as food and medicine since ancient times. Honey has long been used for treatment of various diseases in folk medicine around the world. The present study was planned to explore the effect of Natural Honey (NH) on the intestinal transit of rats. The rats were fed chow, fresh palm oil diet (FPOD), Thermoxidized Palm Oil Diet (TPOD) and NH; and further the transit point was calculated as a percentage of the total length of the intestine. The NH treated rats significantly decreased the intestinal transit of rats compared to other groups. The findings exhibited that natural honey used for the treatment of diarrhoea.
