The Healthy Food Basket Survey carried out by the Cancer Council NSW has found that low-income families in the North West now have to spend an average of 56% of their household budget to maintain a healthy diet, compared to 22% for a family on an average income.
It appears that remote areas of NSW are the hardest hit when it comes to affordability, quality and varieties available of fruit and vegetables.
Nutritionist Kathy Chapman says though it has been proven that a healthy diet and maintaining a healthy weight is one of the most important lifestyle choices in preventing cancer, if you have a low income and also live in a remote part of the state it is much harder to follow such a lifestyle.
The study revealed that the cost of a healthy food basket for a family of six over a two week period varied from $337.29 in Blaxland, Blue Mountains to $519.71 in Murrurundi, in the Hunter region - a difference of 54% between the cheapest and most expensive healthy basket of food.
The study also found the cost of a healthy food basket varied within metropolitan and regional areas and even in Sydney there was a $150 difference between the cheapest and most expensive healthy food basket.
The Cancer Council says price differences within the same region indicates something other than transport costs are influencing prices and they are calling on the government to regularly monitor food prices to ensure all families are able to afford a healthy food basket.
The study also found for as little as $2.58 per day that an individual can meet their daily dietary recommendations of two serves of fruit and five serves of vegetables and they advise consumers to look for cost effective fruits and vegetables such as bananas, oranges, beans, carrots, sweet potato, broccoli and cauliflower.
They also recommend shoppers choose fruit and vegetables that are in season in order to get the best value for money.

Zhang and his colleagues tested the ability of the concentrate to prevent bladder tumors in five groups of rats. The first group acted as a control, while the second group was given only the broccoli extract to test for safety. The remaining three groups were given a chemical, N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) in drinking water, which induces bladder cancer. Two of these groups were given the broccoli extract in diet, beginning two weeks before the carcinogenic chemical was delivered.
In the control group and the group given only the extract, no tumors developed, and there was no toxicity from the extract in the rats.
About 96 percent of animals given only BBN developed an average of almost two tumors each of varying sizes. By comparison, about 74 percent of animals given a low dose of the extract developed cancer, and the number of tumors per rat was 1.39. The group given the high dose of extract had even fewer tumors. About 38 percent of this high-dose group developed cancer, and the average number of tumors per animal was only .46 and, unlike the other animals, the majority were very small in size.
The study was funded by the Vital Vegetables Research Program of Australia and New Zealand, the National Cancer Institute and the Roswell Park Alliance Foundation.
