Type 2 diabetes heredity and nutrient intake. A dietary history assessment in non-obese normoglycaemic men.

: The impact of type 2 diabetes heredity on nutrient intake was studied, by means of dietary histories, in 51 normoglycaemic, non-obese men, aged 54-59 years; 29 with familial aggregation of type 2 diabetes, and 22 with no such family history. The average daily intake of energy, macronutrients and minerals was almost identical in the two groups. Mean energy intake was approximately 2400 kcal/d, about 15 per cent of the energy deriving from protein, 35 per cent from fat, 45 per cent from carbohydrate and 5 per cent from alcohol. The average daily intake or dietary fibre was approximately 17 g, or 7 g/1000 kcal. Mean daily sodium and potassium intake, estimated from food sources, was about 3000 and 4000 mg, respectively. The findings provide no support for the existence of any relationship between type 2 diabetes heredity and dietary habits or nutrient intake.
