Grains and Nutrition

Grains and grain foods are staples in the diets of cultures around the world, and have made an important contribution to daily nutrient requirements since cultivation began around 10,000BC. Their consumption is encouraged in dietary guidelines both in Australia and around the world for the significant contribution these foods make to nutrient intakes.

Cereal grains are high in carbohydrate, low in fat, good sources of protein and provide varying amounts of fibre, vitamins and minerals. The nutritional composition of grains may vary depending on the variety and environmental growing conditions. The protein content of wheat is higher, on average, than that of other cereals.

Grain foods both whole grain and refined make an important contribution to the nutrient intakes of Australians. Grain foods are the leading contributors of seven key nutrients in the Australian diet – fibre, iron, magnesium, iodine, carbohydrates and B-group vitamins including folate and thiamin.

The Australian Dietary Guidelines list distinguishing and significant nutrients for grain foods including carbohydrate, protein, iron, dietary fibre, iodine, magnesium, zinc, the B-group vitamins thiamin, folate, riboflavin and niacin as well as vitamin E. Pseudo-cereals contain similar amounts of these nutrients as grains so are commonly considered as whole grains.

In comparison, oilseeds such as chia seeds are nutritionally different to grains and are not considered grains or whole grains. They have a higher oil content and lower carbohydrate content than grains. Also, seeds including chia contain very little of the B-group vitamins and minerals that are listed as significant nutrients in grains.
