Here's how to shop for healthy foods...

Look out for products with the Heart Mark. These foods will be lower in saturated fat, cholesterol, added sugars and sodium and will also be higher in fibre, where applicable.

Don’t go shopping on an empty stomach! You are more likely to buy too much and to opt for the high fat foods when hungry.

Make a list before you go to the shops and stick to the list as far as possible.

Stock up on fresh fruit and vegetables. Don’t ignore the frozen vegetables though as they make a convenient alternative for fresh ones.

Start to read labels. Look at the fat content. For a healthy low fat product, the fat content should be 3-5g/100g. When choosing oils and margarine, this does not apply.

Choose a soft or tub margarine rather than a hard brick one. Choose an unsaturated oil or a spray oil.

Where possible, buy unprocessed meat, chicken and fish products, unless they have the Heart Mark or are low in fat and salt.

Choose high-fibre breakfast cereals and put some beans and lentils into your trolley for a change.

Look for low fat or fat-free milk and yoghurt when choosing milk products.

Buy tinned fish in water or tomato rather than brine or oil.

When stocking up on snacks, choose low fat yoghurts, vegetable sticks, raw nuts, dried fruit or whole-wheat biscuits.
