Is bread nutritious?

Bread contains a range of nutrients – it’s a good source of carbohydrate, protein and fibre. The amount of vitamins and minerals present in bread depends on the type of flour used and whether vitamins and minerals have been added during processing.

Here's what to look for when choosing a loaf.

Fibre

Fibre helps keep bowel movements regular. It may also help prevent colorectal cancer, and may provide some protection against heart disease.

Adults should eat 25g to 30g of fibre per day.

Toddlers and pre-schoolers don’t need as much fibre as adults: fibre can make a small stomach feel full before the child’s eaten enough food to get the energy and other nutrients it needs.

The Ministry of Health suggests fibre intake should increase as a child gets older. For example, a daily intake of 18g of fibre is adequate for children between 4 and 8 years old. When they’re older (between 9 and 13 years) it should increase to 24g for boys and 20g for girls.

Look for fibre content of 6g or more per 100g. Salba Traditional Soya and Linseed with Ancient Grains has 11.9g of fibre per 100g – the highest in our survey. As a general rule, wheatmeal, wholemeal and wholegrain breads have more fibre than white bread.

Whole grains

There’s compelling evidence whole grains help protect against heart disease and some cancers. They also help control weight because whole grains are denser and so you feel full even though you’ve eaten less. Whole grains tend to be higher in fibre (and vitamins and minerals) than more refined grains.

Look for “whole” grains in the ingredients list – especially whole wheat. Oats, rye and millet are also good sources of whole grains.

Sodium

The Ministry of Health recommends a range of daily sodium intakes. Its recommended maximum daily limit for adults – which is what you can consume without an increased risk of high blood pressure – is 2300mg per day. That’s about 6g of salt (or just over a teaspoon).

Look for a sodium content of 400mg per 100g or less. There are lower-sodium options in all types of bread, including white and wheatmeal.

Fat

Without spreads or fillings, most breads are low fat. Nuts and seeds in a bread boost its fat content – but this is mainly “good” monounsaturated fat. And nuts and seeds are also a source of fibre and other nutrients.

Folate

The benefit of folate (folic acid) is the only "health claim" allowed by the Food Standards Code. Women of childbearing age need adequate levels of folate – both before and during pregnancy – to reduce the risk of having a baby with neural tube defects (NTDs) such as spina bifida. So added folate can be helpful for those who don't get enough folate from their diet.
