Eggs, yoghurt and cheese might all help to cut the risk of developing diabetes, according to Scandinavian researchers.
One study in Finland found that men who ate four eggs a week cut their risk of developing type 2 diabetes by 37% compared with those eating one a week.
The research involved some 2,332 men, studied at the University of Eastern Finland.
Researchers said eggs might contain some helpful nutrients as well as simply helping to cut the appetite for carbohydrates.
The research was reported in the American Journal of Clinical Nutrition.
A second study in Sweden, in the same journal, linked high fat yoghurt and cheese to a 20% reduced risk of type 2 diabetes.
Eating meat increased the risk, researchers found.
The findings come from a study of more than 27,000 people conducted over a 20 year period.
Researcher Ulrika Ericson said: "We have taken into account many dietary and lifestyle factors in our analysis, such as fermentation, calcium, vitamin D and physical activity. However, there may be other factors that we have not been able to measure that are shared by those who eat large quantities of high-fat dairy products.
"Moreover, different food components can interact with each other. For example, in one study, saturated fat in cheese appeared to have less of a cholesterol-raising effect than saturated fat in butter."
