Fresh fish oil given to overweight pregnant rats prevented their offspring from developing a major diabetes risk factor, Auckland researchers have found.
The pregnant rats were fed either a high-fat diet to make them overweight, or a standard diet, and half from each group were also given fresh fish oil. In the offspring of the high-fat group, the fish oil treatment improved the way insulin works, which is protective against diabetes.
"This is exciting because it raises the question: if overweight women take fresh fish oil in pregnancy, will it lower the risk of their children later developing diabetes?" says Dr Ben Albert, who led the research with Professor Wayne Cutfield, both at the University of Auckland-based Liggins Institute.
But he cautions against pregnant women taking fish oil on the basis of this finding - yet.
"The same benefit has not yet been shown in humans, and our earlier study shows New Zealanders cannot be sure that the fish oil they buy is fresh."
The current findings, published in high-ranking journal Scientific Reports, are part of a series of studies by the same team into the potential of omega 3 in fish oil to reduce the risk of diabetes and other obesity-related illnesses.
"Studies by other researchers using adult rats have shown that omega 3 fatty acids in fresh fish oil improve the way insulin works, which protects against diabetes and related diseases," says Dr Albert. "We wondered if it could also be protective during pregnancy, p
