A study that appeared in the Journal Nature has revealed some bitter facts about sugar. As per a group of American researchers, sugar is so harmful for the human body that it should be treated in the category of alcohol and tobacco-related products.

Lead author Dr. Robert Lustig, a childhood obesity expert from the University of California, told that sugar is one of the major culprits behind the world's major killers like heart attacks, other heart-related problems, cancer, diabetes and infections.

Lustig told that a lot of difference has come with the passage of time. Earlier, people used to have sugar in the form of fruits, and that too for just few months during the harvesting time.

Otherwise, they used to have sugar as honey which was also natural. Now, every food product contains artificial sweetener which is causing harm to the human body. Lustig told that obesity due to sugar is the latest concern among researchers. This is the reason that the study researchers have called for a ban on the sugary products, and they have said that the ban should be strictly followed in developing countries.

Lustig told, "If international bodies are truly concerned about public health, they must consider limiting fructose - and its main delivery vehicles, the added sugars HFCS and sucrose - which pose dangers to individuals and to society as a whole".

The Government should also ban cafeteria in the schools, and should also not also vendors to stand outside schools to sell their sugar processed food items. Lustig told that the Government should also double the tax amount on such products so that children are not able to buy them.

There are some countries which have been coming forward and have started to levy taxes on such food items. Canada is one of the countries which have increased tax rates on some sweetened food items.
