According to a new study from researchers at Chalmers University of Technology, Sweden, and the Danish Cancer Society Research Centre, wholegrains can help prevent type 2 diabetes.
The study showed that it made no difference which type of wholegrain product or cereal the participants ate – ryebread, oatmeal, and muesli, for example, seem to offer the same protection against type 2 diabetes.
Wholegrains are defined as consisting of all three main components of the grain kernel: endosperm, germ, and bran. Those who avoid all cereals, in an attempt to follow a low carb diet, therefore lose out on the positive health effects of wholegrain, which come principally from the bran and the germ.
The participants were divided into 4 different groups, based on how much wholegrain they reported eating. Those with the highest consumption ate at least 50 grams of wholegrain each day. This corresponds to a portion of oatmeal porridge, and one slice of rye bread, for example.
The proportion who developed type 2 diabetes was lowest in the group which reported the highest wholegrain consumption, and increased for each group which had eaten less wholegrain. In the group with the highest wholegrain intake, the diabetes risk was 34 percent lower for men, and 22 percent lower for women, than in the group with the lowest wholegrain intake.
