I am really keen to change my diet but this is a task I feel is made difficult by the expense of eating healthily. I was looking around the supermarket the other day and was really surprised at the overall prices of the fresh fruits and vegetables, fish and nuts/seeds. If I were to start buying more of these foods it would increase and already tight budget for food. I also tend to find with the fresh fruits and vegetables that the shelf-life if quite short on them. This makes it difficult to buy in bulk (which can be cheaper) as a lot of the fruits and vegetables go off by the time I come to use them. I know I could buy frozen vegetables, but are they nutritionally valuable or have they lost their health benefits?
So my question is: have any of you got tips for eating healthily on a budget?
