What criteria should I use to decide which bread to buy at the supermarket?

It can be confusing with the large selection of bread available. Here are some points to assist with your decision making:
Most breads are low-fat and low-sugar. Exceptions to this rule are breads with a high seed content as seeds are around 50% fat, although this fat is considered healthy. Also fruit bread is higher in sugars due to the added fruit.
A wholegrain or wholemeal bread is recommended for everyday eating by adults. Including whole grain breads in the diet helps protect against developing heart disease, type 2 diabetes as well as better weight control. Read the ingredients list on bread packaging to identify the grains present. Terms to look for include: whole grain, whole wheat, stone ground (grain), rye, kibbled (grain), brown rice, barley, oats, millet.
