Multigrain, wholegrain, wholemeal: what's the difference and which bread is best?
With so many choices of bread available, it's hard to know which is best for us
Choices include wholemeal, wholegrain, multigrain, sourdough, rye and low GI

Bread has always been a dietary staple in most households – it's a good source of carbohydrate and it's
low in fat.
We all know that wholemeal is better for us than white bread. But how does wholemeal, wholegrain
and multigrain compare? And what about sourdough, rye, high fibre white, low GI, low FODMAP and
gluten-free?
With so many choices of bread available, it's hard to know which is best for our health.
Writing for The Conversation, Leah Dowling, lecturer in dietetics at Swinburne University of Technology,
gives her take on each type.

White bread vs wholemeal
Due to the grains being ground down during processing, white and wholemeal breads have a higher
glycaemic index (GI) than wholegrain bread. This results in glucose being released into the bloodstream
more quickly.
Foods with a high GI index can can cause blood sugar spikes and have been liked to a raised risk of
developing type 2 diabetes.
Regular consumption of lower GI foods helps to regulate blood glucose levels, keeping us fuller for
longer, and helping us eat fewer calories to keep our weight in check.
Wholemeal bread has a lower glycaemic index (GI) which is healthier as it's better for our sugar levels.
Wholemeal bread has a lower glycaemic index (GI) which is healthier as it's better for our sugar levels.
Furthermore, white bread is made from wheat that has had the germ and bran removed, thereby
reducing the fibre, B group vitamins, vitamin E and minerals such as iron, zinc, magnesium and
phosphorus.

Wholemeal bread is made from wholegrains that have been milled to a fine texture, giving a plain brown
appearance.
Wholemeal flour contains more fibre than white flour. Wholemeal bread also contains more vitamins
and minerals than many white breads, but has a higher GI than wholegrain breads.
What about white bread labelled 'high fibre'?
High fibre white breads are white breads that have fibre added to them. This makes them a better
choice than regular white bread especially for children (or fussy adults) who won't eat wholegrain bread.
Wholegrains
Wholegrain bread has a dense wholemeal flour base and well as lots of grain and seeds.
They contains the entire grain: the bran (outer layer), endosperm (starchy middle layer) and germ
(nutrient rich inner part).
It's a rich source of carbohydrates, protein, unsaturated (good) fats, vitamins and minerals and healthy
fats as well as three types of fibre: soluble, insoluble and resistant starch.
Diets high in wholegrains are linked to a reduced risk of health conditions such as excess weight and
obesity, heart disease, type 2 diabetes and some cancers.
The high dietary fibre helps keep us feeling full. It is also beneficial for bowel health by preventing
constipation and feeding the 'good' gut bacteria which is likely to result in a number of health benefits.
A recent study found a diet high in wholegrains was associated with a lower risk of bowel cancer.
Soy and linseed bread has the added benefit of healthy omega 3 fats. Wholegrain bread is low GI as are
wholemeal breads with added grains.
Multigrain bread
Often multigrain bread is made from white flour with some added grains.
Despite this, multigrain breads tend to have more fibre and a lower GI than white bread, resulting in
longer lasting energy.
Rye bread
Wholegrain rye with added grains has more fibre and vitamins than light rye
Wholegrain rye with added grains has more fibre and vitamins than light rye. Rye bread has a heavier
texture due to a lower gluten content (but it's not gluten free).

Wholegrain rye with added grains has a higher fibre and vitamin content than light rye and has a lower
GI, as does rye sourdough.
Wholegrain rye is a good choice for health and even light rye is better than white.
Sourdough
Sourdough bread has a lower GI due to the higher acidity level. Fibre, vitamin and mineral levels vary
with the flour used, with wholegrain sourdough being the preferred choice.
Be sure to choose an authentic sourdough, as some are faux sourdough and contain yeast rather than
the traditional starter.
Sourdough bread has a lower GI due to the higher acidity level.
Sourdough bread has a lower GI due to the higher acidity level.
Authentic sourdough takes a long time to produce and results in an acidic and chewy bread, two
features that lower the GI.
Look for a chewy texture and the absence of yeast in the ingredients, preferably with wholewheat flour
or rye wholemeal, grains and seeds.
Gluten free
Gluten free breads are made from an alternative grain to wheat, so as to avoid the wheat protein
gluten.
Traditionally, gluten free breads have had a lower fibre content and higher GI than their wheatcontaining counterparts, although, there are now some with added seeds.
These breads are useful for people with a gluten intolerance such as coeliac disease, but offer no
additional health benefits beyond regular breads for the rest of us.

GLUTEN FREE FOODS CONTAIN MORE FAT AND LOWER PROTEIN AND FIBRE THAN EQUIVALENTS
Gluten free foods contain more fat, salt and sugar than their gluten-containing equivalents, and are
generally more than twice has expensive, a study published yesterday found.
Researchers at the University of Hertfordshire said it was clear that gluten free (GF) products offer no
nutritional advantage to regular foods and are not a healthier alternative, which may surprise many
consumers.
They also found that gluten free foods were 159% more expensive than their regular counterparts.
A study found that gluten free products are not healthier alternatives to regular food – and they're
considerably more expensive too.

More than 1,700 food products from Tesco, Asda, Sainsbury’s, Morrisons and Ocado, were compared by
researchers.
They found that, with the exception of crackers, gluten free foods contained more fat, salt and sugar
and also had lower fibre and protein content than their equivalents.
A GF diet is the only treatment option for those who suffer from coeliac disease but many more people
in the UK and around the world avoid gluten foods as it is perceived to contribute towards a healthy
lifestyle.
This has lead to a huge increase in sales of GF foods in recent years.
A gluten free diet – of which Victoria Beckham Gwyneth Paltrow and Miley Cyrus are said to be fans –
avoids the proteins found in wheat, rye and barley.
Advocates believe our modern diets have become increasingly high in refined wheat products and
believe over consumption may lead to digestive symptoms such as bloating, pain and stomach cramps in
those who are sensitive to gluten.
It is believed that around 13 per cent of the UK population are gluten-free. And the figure is even higher
in the US, with a quarter saying they had consumed such foods in 2015 – a 67 per cent increase in two
years.
The findings come after gastroenterologist Dr Suzanne Mahady, a senior lecturer, Monash University,
earlier this week said only those diagnosed with coeliac disease – caused by a reaction of the immune
system to gluten, which is different to gluten sensitivity – should keep to the strict diet.
