CSIRO's non GM barley grain variety

BARLEYmax a nutritious wholegrain

  • A wholegrain has all three components of the grain: the germ, endosperm and bran layers as shown in the graphic above. See an indepth coverage of wholegrains at the Linus Pauling Institute at the Oregon State University: Whole Grains
  • Highly processed grains can remove the bran and the germ leaving a nutrient poor, carbohydrate rich endosperm component.
  • You only need 4 serves of wholegrain based foods for health and this is only about 48 grams per day.
  • BARLEYmax is a rich source of resistant starch which is a fibre that resists digestion in the small intestine where most fibres are broken down. The resistant starch thus passes through to the large intestine where it is fermented by the large bowel bacteria which use the resistance starch as fuel to form short chain fatty acids and in particular butyrate to help protect the bowel. Butyrate is a favoured fuel source of the cells lining the bowel and it has been shown to help reverse cancerous changes in the bowel cells.
  • You need around 20 grams of resistant starch in the diet and this level of intake suggested by the CSIRO is four times greater than average intakes in the western world.

Glycemic Index and Glycemic Load of BARLEYmax

  • BARLEYmax has a GI of 50 [normal barley has a GI of 77]
  • Glycemic Load [GL] was 10 for a standard breakfast cereal quantity whereas the GL of a standard barley breakfast had a GL of 25.
  • To understand a little more about GI/GL please view the following tutorial: GI GL Made Easy
  • Having a low GI/GL means that this new grain has the potential to decrease insulin demand. The CSIRO research team investigating the effects BARLEYmax on insulin made the following statement
    "...may be of value in foods designed to assist in the prevention and management of diabetes."

Health benefits of wholegrains [BARLEYmax Health Nutrition Report from CSIRO]

  • 20 - 40% decrease risk for heart disease
  • Can assist in weight control due to the increased fibre and satiety [fullness]
  • 20 - 30% decreased risk of diabetes
  • Improved bowel health and regularity
  • May help to lower blood pressure
  • Soluble fibre found in barley can help lower cholesterol and LDL [the bad cholesterol]
  • May decrease the risk of colon cancer by 30 - 40%
