In the late 1990s, diet remains the cornerstone of diabetes therapy. Dietar
y and nutritional recommendations should seek to reduce the hyperglycaemic
state which is the main risk factor for microangiopathy. Furthermore, the p
revention of macrovascular complications should lead to dietary prescriptio
ns that combine such properties as antiatherosclerotic, antithrombotic, and
antihypertensive measures and such advantages as reducing oxidative stress
. The means for achieving such objectives are, first, weight-loss intervent
ions in obese patients and,secondly, the choice of a judicious balance betw
een carbohydrates and monounsaturated fats in ail individuals. Dietary meas
ures must achieve a compromise between their acceptability by the patient a
nd medical requirements. For that reason, caloric restriction should he mod
erate, leading to progressive weight loss (- 3 kg monthly), with reasonable
weight targets at the end of the weight-reduction period. Compliance with
dietary advice usually results in significant savings in medical costs. How
ever, long-term maintenance of dietary measures is difficult to achieve in
most individuals, except those enroled in well-structured training programm
es.
