I also agree with Caulfieldkid's comment a great extent. However, it is also the collective will – of the government – and I mean the political will, who has to change things through regulations.
Markets were created for a certain reason and as in case of food – additives were added for shelf life for 5 months (just a number) but if additives are added for increasing its shelf life of canned potatoes, beans or carrots for 5 years (another number),it changes the chemical composition of the vegetable/sea food and we are eating something that looks like vegetables/sea food – That’s where the problem lies and more.
Of course it is for the profits of the business man, because if the farmer does not have a good yield of potatoes this year (because of weather) and he has already sold it to the business man at a set price, as written in the contract it is profitable to the farmer. In another case a highly unexpected yield is profitable for the business man who now has more vegetables to be canned – he puts more additives and increases its shelf life.
But the fact is government and markets create a symbiotic relationship in order to reign! - Think Monsanto - the food terrorist.
Governments are elected representatives of the people, which means official power legally and have the opportunity to put laws and regulations to ensure maximum benefit to majority. And so yes, governments are responsible. But again governments also behave like markets. The government also want to remain in business as long as they can and they do not want to make their businessman who has supplied many campaign dollars unhappy.
Bix, when I started writing the answer to your question I thought I had an Indian perspective,but while writing I realized that – the common factors that make up the market and the government are similar in every country. Except the weather, the cultural, notions of freedom, political(india mostly have a socialistic regime and democracy is a stalemate) and social milieu differs.
